This study examined in detail the interrelationships among kinematic variables to discern the strategies for deglutitive hyoid motion during discrete (5 cc, 10 cc, 20 cc, 30 cc) & rapid sequential (120 cc) swallowing tasks. Submental ultrasound was conducted with head & transducer stabilization on 30 healthy subjects (15 males, 15 females) in three age groups (20-39, 40-59, 60-79 yrs). Frame-by-frame changes in hyoid position were tracked from digitized images of 236 discrete & 318 rapid sequential swallows. Repeated-measures analyses of variance were conducted on a number of kinematic variables with corrections for multiple tests & comparisons. The main effect of task was significant for all variables except forward peak velocity. Per post hoc contrasts, rapid sequential swallows had significantly reduced maximal amplitude (maximal displacement), total distance, backward peak velocity, at-max & total durations, & time to backward peak velocity in comparison with discrete swallows of any volume. Amplitude "down-scaling" was the prominent kinematic strategy used to accomplish rapid sequential swallows in a shorter time while keeping forward peak velocity essentially unchanged. In contrast, amplitude "up-scaling" was the strategy for accommodating larger-volume discrete swallows. Our results confirm built-in flexibility in the functional range of deglutitive hyoid motion.

AN - 85272067; pmid-12111969 AB - An 8-channel receive-only detector array was developed for SENSE MRI of human brain. The coil geometry was based on a gapped element design and used ultra-high impedance preamplifiers for mutual decoupling of the elements. Computer simulations of the electric and magnetic fields showed that excellent signal-to-noise ratio (SNR) and SENSE performance could be achieved by placing the coil elements close to the head and maintaining a substantial gap between the elements. Measurements with a 1.5 T prototype coil showed a 2.7-fold improvement of the SNR averaged over the brain compared to a conventional quadrature birdcage receive coil and an average geometrical noise amplification factor (g-value) of 1.06 and 1.38 for rate-2 and rate-3 SENSE, respectively.

The model incorporates plasma kinetics, transcapillary transport, lymphatic clearance, interstitial diffusion in both the normal tissue and tumor, and binding reactions. We use results from the FE analysis to assess previous predictions that employed either a Dirichlet boundary condition (b.c.), or an approximate, composite (Dirichlet and Neumann) b.c. at the tumor surface. We find that the Dirichlet b.c. significantly overpredicted the mean total tumor mAb concentration. In contrast, the composite b.c. yielded good agreement with FE predictions, except at early times. We also used the FE model to investigate the influence of the approximately 30-fold difference in the values of mAb diffusion coefficient measured by Clauss and Jain (Cancer Res. 50:3487-3492, 1990) and Berk [et_al.] (Proc. Natl. Acad. Sci. U.S.A. 94:1785-1790, 1997). For low diffusivity, diffusional resistance slows both mAb uptake by and efflux from the tumor. For high diffusivity at the same mAb dose, more rapid uptake produces earlier and higher peak mAb levels in the tumor, while the efflux rate is limited by the dissociation of the mAb-tumor antigen complex.

Here we report that ectopic expression of human telomerase reverse transcriptase (hTERT) in BMSSCs extended their life-span and maintained their osteogenic potential. In xenogenic transplants, hTERT-expressing BMSSCs (BMSSC-Ts) generated more bone tissue, with a mineralized lamellar bone structure and associated marrow, than did control BMSSCs. The enhanced bone-forming ability of BMSSC-Ts was correlated with a higher and sustained expression of the early pre-osteogenic stem cell marker STRO-1, indicating that telomerase expression helped to maintain the osteogenic stem cell pool during ex vivo expansion. These results show that telomerase expression can overcome critical technical barriers to the ex vivo expansion of BMSSCs, and suggest that telomerase therapy may be a useful strategy for bone regeneration and repair.

AN - 72075141; 12222686 AB - We describe here our recent studies of the DNA binding properties of Msh2-Msh6 and Mlh1-Pms1, two protein complexes required to repair mismatches generated during DNA replication. Mismatched DNA binding by Msh2-Msh6 was probed by mutagenesis based on the crystal structure of the homologous bacterial MutS homodimer bound to DNA. The results suggest that several amino acid side chains inferred to interact with the DNA backbone near the mismatch are critical for repair activity. These contacts, which are different in Msh2 and Msh6, likely facilitate stacking and hydrogen bonding interactions between side chains in Msh6 and the mismatched base, thus stabilizing a kinked DNA conformation that permits subsequent repair steps coordinated by the Mlh1-Pms1 heterodimer. Mlh1-Pms1 also binds to DNA, but independently of a mismatch. Mlh1-Pms1 binds short DNA substrates with low affinity and with a slight preference for single-stranded DNA. It also binds longer duplex DNA molecules, but with a higher affinity indicative of cooperative binding. Indeed, imaging by atomic force microscopy reveals cooperative DNA binding and simultaneous interaction with two DNA duplexes. The novel DNA binding properties of Mlh1-Pms1 may be relevant to signal transduction during DNA mismatch repair and to recombination, meiosis and cellular responses to DNA damage.

AN - 72066659; 12215216 AB - By taking advantage of established CD45-deficient DT40 cells, the roles of CD45 in oxidative stress signaling were investigated. Using p-nitrophenyl phosphate as substrate, it was found that CD45 constituted nearly 40% of the total protein-tyrosine phosphatase activity. Almost 90% of the phosphatase activity was rapidly inactivated upon hydrogen peroxide treatment. Hydrogen peroxide-induced tyrosine phosphorylation of cellular proteins and c-Jun N-terminal kinase activation were markedly enhanced in CD45-deficient cells relative to that in its parental cells. In comparison, hydrogen peroxide-induced inositol 1,4,5-trisphosphate production and Ca(2+) mobilization were impaired in CD45-deficient DT40 cells. However, hydrogen peroxide-induced tyrosine phosphorylation of phospholipase Cgamma2 (PLCgamma2), phosphatidylinositol 3-kinase activity precipitated by anti-phosphotyrosine antibody, and activation of Bruton's tyrosine kinase appeared intact in CD45-deficient DT40 cells. This suggests that CD45 mediates the ability of hydrogen peroxide-activated PLCgamma2 to hydrolyze its substrate via a mechanism independent of both tyrosine phosphorylation of PLCgamma2 and phosphatidylinositol 3-kinase, as well as activation of Bruton's tyrosine kinase. Taken together, our observations demonstrated that, in addition to its negative regulatory or phosphatase activity, CD45 has a positive role in oxidative stress signaling.

AN - 71993181; 12170567 AB - Methadone is not a new analgesic drug [69]. Several studies have demonstrated that methadone is a valid alternative to morphine, hydromorphone, and fentanyl for the treatment of cancer-related pain, and extensive reviews on the subject have been published in recent years [10,23,25,64,70,71]. Most people involved in pain therapy, however, are not well informed about the properties of methadone. The authors believe that the low cost of methadone paradoxically contributes to the limited knowledge of its characteristics and to the restricted therapeutic use of this drug. The low cost of methadone means there is little financial incentive for pharmaceutical companies to invest in research or to disseminate scientific information. Unfortunately, the lack of scientific information from pharmaceutical companies frequently results in a lack of knowledge on the part of physicians. Unless the existing approach changes, both culturally and politically, ignorance about methadone will persist among medical experts. The low cost of methadone, rather than being an advantage, will result in the limited exploitation of an effective drug.

AN - 71989462; 12151130 AB - Kindling, in the classical sense, involves progressively increasing responsivity to the intermittent repetition of the same 1-s subthreshold electrical stimulation over time, with the amygdala being the area most frequently studied. Such repeated subthreshold stimulation is associated with: lowering of the after-discharge (AD) threshold; lengthening and spread of the AD; marked seizure stage progression culminating in full-blown tonic-clonic forelimb convulsions with rearing and falling; and evolution from triggered to spontaneous seizures. This evolving process concomitantly involves changes in the spatio-temporal expression of immediate early genes (IEGs), neurotrophic factors, and late effector genes (LEGs), and an associated changing pattern of effectiveness of different pharmacological interventions. Since seizures are the paradigmatic behavioral manifestation of kindling, some types of pharmacological seizures, such as those induced by the local anesthetics cocaine and lidocaine, and some epileptic syndromes, are most likely homologously modeled by kindling. However, since non-epileptiform syndromes, such as recurrent episodes of affective illness and some pain syndromes possess non-homogenous elements of kindling-like evolution, some of the principles involved in kindling progression may, nonetheless, be pertinent to the understanding and treatment of these syndromes. For example, one could attempt to distinguish between the genes involved in the primary pathological processes of syndrome evolution versus those that are secondary and adaptive; such a differentiation could have important implications for the development of therapeutic approaches targeted to suppressing or enhancing these alterations, respectively. In these instances, inferences drawn from the kindling model are necessarily indirect and circumscribed because different neuroanatomical and biochemical processes are likely involved in the evolution of each neuropsychiatric syndrome. Given these recognized limitations of non-homologous models, kindling may still provide insights into the longitudinal course, progression, and treatment of some neuropsychiatric syndromes that can then be directly tested in the clinic.

AN - 71987756; 12148789 AB - Cohen's ecological analysis of US lung cancer mortality rates and mean county radon concentration shows decreasing mortality rates with increasing radon concentration (Cohen 1995 Health Phys. 68 157-74). The results prompted his rejection of the linear-no-threshold (LNT) model for radon and lung cancer. Although several authors have demonstrated that risk patterns in ecological analyses provide no inferential value for assessment of risk to individuals, Cohen advances two arguments in a recent response to Darby and Doll (2000 J. Radiol. Prot. 20 221-2) who suggest Cohen's results are and will always be burdened by the ecological fallacy. Cohen asserts that the ecological fallacy does not apply when testing the LNT model, for which average exposure determines average risk, and that the influence of confounding factors is obviated by the use of large numbers of stratification variables. These assertions are erroneous. Average dose determines average risk only for models which are linear in all covariates, in which case ecological analyses are valid. However, lung cancer risk and radon exposure, while linear in the relative risk, are not linearly related to the scale of absolute risk, and thus Cohen's rejection of the LNT model is based on a false premise of linearity. In addition, it is demonstrated that the deleterious association for radon and lung cancer observed in residential and miner studies is consistent with negative trends from ecological studies, of the type described by Cohen.

AN - 71986901; 12164691 AB - Regional delivery of drugs can offer a pharmacokinetic advantage in the treatment of localized tumors. One method of regional delivery is by intra-arterial infusion into the basilar/vertebral artery network that provides local access to infratentorial tumors, which are frequent locations of childhood brain cancers. Proper delivery of drug by infused solutions requires adequate mixing of the infusate at the site of infusion within the artery lumen. Our mixing studies with an in vitro model of the vertebral artery network indicate that streaming of drug solution is likely to occur at low, steady infusion rates of 2 ml/min. Streaming leads to maldistribution of drug to distal perfused brain regions and may result in toxic levels in some regions while concurrently yielding subtherapeutic levels in adjacent regions. According to our model findings, distribution to both brain hemispheres is not likely following infusion into a single vertebral artery even if the infusate is well-mixed at the infusion site. This outcome results from the unique fluid flow properties of two converging channels, which are represented by the left and right vertebral branches converging into the basilar. Fluid in the model remains stratified on the side of the basilar artery served by the infused vertebral artery. Careful thought and planning of the methods of intravertebral drug infusions for treating posterior fossa tumors are required to assure proper distribution of the drug to the desired tissue regions. Improper delivery may be responsible for some noted toxicities or for failure of the treatments.

This global view has led to a deeper understanding of the mechanism of action, the elimination of non-specific and undesirable side effects and, ultimately, greater efficacy and reduced toxicity for nucleic acid medicines. Several antisense oligonucleotides are in clinical trials; these are well tolerated and have therapeutic potential.

AN - 71907445; 12119277 AB - Functions attributed to phospholipase (PL) D include the regulation of intracellular trafficking of Golgi-derived vesicles and secretion of granules from mast cells. We have reported that activation of PLD and secretion in a rat mast cell (RBL-2H3) line is substantially enhanced by cholera toxin, a known activator of protein kinase (PK) A. Here we review the evidence that (1) the synergistic interactions of cholera toxin and other pharmacological agents on mast cell secretion are attributable to the synergistic activation of PLD via PKA, CaM kinase II, and PKC and (2) both PLD1 and PLD2 participate in this process. For example, treatment with cholera toxin, thapsigargin, and phorbol 12-myristate 13-acetate (which activate PKA, CaM kinase II, and PKC, respectively) exhibit synergy in the stimulation of both PLD and secretion. These kinases and PLD are likely confined to membrane components, as similar synergistic interactions could be demonstrated in permeabilized cells. The regulation of PLD and secretion by these kinases is also apparent from studies of inhibitors of PKA and other kinases. Also, by overexpression of either PLD1 or PLD2 it is apparent that both isoforms respond to the same stimuli as endogenous PLD, although PLD1 is largely associated with secretory granules and PLD2 with plasma membrane. The studies reveal interesting differences in the regulation of the translocation of granules (regulated by PKA) and the fusion of these granules with the plasma membrane (regulated by Ca(2+) and PKC). The pathological/physiological implications of the regulation of PLD by PKA require further evaluation in other cell systems.

AN - 71896077; 12116270 AB - Pharmacological and electrophysiological evidence has shown that opioid receptors are involved in the mechanism of heroin dependence. Thus, opioid receptors are appropriate candidate genes for case-control association studies of heroin dependence. Previously, two single nucleotide polymorphisms (SNPs), OPRD1 921T > C and 80G > T, of the human delta opioid receptor gene were used in population-based studies of heroin dependence. One study in a German population found that OPRD1 921T > C was associated with heroin dependence. This finding, however, was not replicated in a different German sample. To test the hypothesis that OPRD1 or a closely linked gene is associated with heroin dependence, we used 5' nuclease assays to genotype both OPRD1 SNPs in 450 Chinese heroin dependent patients and 304 unaffected controls from the same population. In addition, five SNPs distributed in four other genes: ADH2, ALDH2, OPRM1, and DRD1, were used as genomic control loci to test the case and control populations for stratification bias. Genotype and allele frequencies at OPRD1 921T > C were not significantly different, and the OPRD1 80G was absent from both Chinese opioid dependence patients and controls. Based on the genotype and allele frequencies of the genomic control loci, there was no evidence for stratification bias capable of masking an association of OPRD1 to heroin dependence in this large and homogenous Chinese sample. Therefore, these data do not support an association between the OPRD1 gene and heroin dependence in the Chinese population. Published 2002 Wiley-Liss, Inc.

AN - 71893609; 12105088 AB - Methamphetamine (METH) abuse is a growing health problem, and no treatments for METH dependence have been identified. The powerful addictive properties of METH are mediated by release of dopamine (DA) from nerve terminals in mesolimbic reward pathways. METH stimulates DA release by acting as a substrate for DA transporter (DAT) proteins, thereby triggering efflux of DA from cells into the synapse. We have shown that blocking DAT activity with high-affinity DA uptake inhibitors, like GBR12909, can substantially reduce METH-evoked DA release in vitro, suggesting GBR12909 may have potential as a pharmacotherapy for METH dependence. The purpose of the present study was to examine the neurobiological effects of a long-acting oil-soluble preparation of GBR12909 (1-[2-[bis(4-fluorophenyl)methoxy]ethyl]-4-(3-hydroxy-3-phenylpropyl) piperazinyl decanoate, or GBR-decanoate). Male rats received GBR-decanoate (480 mg/kg, i.m.) or its oil vehicle, and were tested using a variety of methods one and two weeks later. Ex vivo autoradiography showed that GBR-decanoate decreases DAT binding in DA-rich brain regions. In vivo microdialysis in the nucleus accumbens revealed that GBR-decanoate elevates baseline levels of extracellular DA and antagonizes the ability of METH to evoke DA release. The dopaminergic effects of GBR-decanoate were sustained, lasting for at least two weeks. Rats pretreated with GBR-decanoate displayed enhanced locomotor responses to novelty at one week, but not two weeks, postinjection. Administration of the D(2)/D(3) receptor agonist quinpirole (10 and 100 microg/kg, s.c.) decreased locomotor activity and suppressed plasma prolactin levels; quinpirole-induced responses were not altered by GBR-decanoate. Thus, GBR-decanoate is able to elevate basal synaptic DA levels and block METH-evoked DA release in a persistent manner, without significant perturbation of DA receptor function. The findings suggest that GBR-decanoate, or similar long-acting agents, should be evaluated further as potential treatment adjuncts in the management of METH addiction in humans.

AN - 71890654; 12105089 AB - Several lines of evidence support a dual-deficit model of stimulant withdrawal in which decreases in synaptic dopamine (DA) and serotonin (5-HT) contribute to withdrawal symptoms, drug craving, and relapse. According to the dual-deficit model, DA dysfunction during withdrawal underlies anhedonia and psychomotor disturbances, whereas 5-HT dysfunction gives rise to depressed mood, obsessive thoughts, and lack of impulse control. The model suggests that medications capable of normalizing stimulant-induced DA and 5-HT deficits should be effective treatment adjuncts. Furthermore, the model may explain why medications targeting only one neurotransmitter system (i.e., DA) have failed to treat cocaine dependence. Amphetamine-type appetite suppressants are logical choices for neurochemical normalization therapy of stimulant dependence, yet few clinical studies have tested anorectics in this regard. The chief purpose of the present work is to profile the activity of various anorectic agents at DA, 5-HT, and NE transporters, in order to identify possible medications for stimulant dependence. Compounds were tested in vitro for their ability to stimulate release and inhibit uptake of [(3)H]DA, [(3)H]NE, and [(3)H]5-HT. Selected compounds were tested in vivo for their ability to elevate extracellular levels of DA and 5-HT in rat nucleus accumbens. The results show that clinically available appetite suppressants display a wide range of activities at monoamine transporters. However, no single medication possesses equal potency at DA and 5-HT transporters, suggesting that none of the anorectics is ideally suited for treatment of stimulant addictions.

AN - 71856432; 12082011 AB - Risk assessment involves the identification of potential human health hazards, the assessment of the level of exposure by humans to these hazards and the evaluation of the relationship between exposure and response in humans. Research is currently underway to improve the scientific basis of risk assessment through the incorporation of new technologies such as transgenic animals, molecular epidemiology, toxicogenomics, alternative models to animals and mechanism-based mathematical modeling into the estimation of risk in a quantitative manner. This paper briefly discusses these technologies and how each is being employed for more scientifically sound risk assessments.

AN - 71829339; 12069314 AB - This study was designed to investigate the composition and toxicity of solid residues from bauxite manufacturing plants. Soil and dust samples were collected in the proximity of two bauxite plants (Gardanne, France, and Portovesme, Italy). Samples were analyzed for their content of some selected inorganic contaminants by means of inductively coupled plasma optical emission spectroscopy (ICP-OES) either following acid digestion procedures or by seawater release of soluble components. Toxicity was tested by sea urchin bioassays to evaluate a set of toxicity endpoints including acute embryotoxicity, developmental defects, changes in sperm fertilization success, transmissible damage from sperm to the offspring, and cytogenetic abnormalities. Inorganic analysis showed two distinct sets of inorganic contaminants in Gardanne versus Portovesme, including Al, Cr, Cu, Fe, Mn, Pb, Ti, and Zn; sample composition (seawater-soluble contaminants) and toxicity showed a noteworthy association. The most severe toxicity to embryogenesis and to sperm fertilization success was exerted by some Portovesme samples (0.03-0.5% w/v), with a significant association between toxicity and dose-related seawater release of Zn, Pb, and Mn. Seawater extraction of a toxic dust sample (G20) from the Gardanne factory showed increasing seawater release of Al, Fe, and Mn; the G20 sample, at the level of 0.5%, affected both developing sea urchin embryos and sperm (offspring quality). Soil samples around the Gardanne factory showed the highest frequency of toxic soil sites eastward from the factory. The present data point to solid deposition from bauxite plants as a potential subject of environmental health concern. The results suggest that extraction methods for evaluating the toxicity of complex mixtures should be based on the environmental availability of mixture components. The differences in sample toxicity among the tested sites, however, suggest possible site-to-site variability in geochemical and/or technological parameters.

AN - 71828849; 12070308 AB - TGF-betas play diverse and complex roles in many biological processes. In tumorigenesis, they can function either as tumor suppressors or as pro-oncogenic factors, depending on the stage of the disease. We have developed transgenic mice expressing a TGF-beta antagonist of the soluble type II TGF-beta receptor:Fc fusion protein class, under the regulation of the mammary-selective MMTV-LTR promoter/enhancer. Biologically significant levels of antagonist were detectable in the serum and most tissues of this mouse line. The mice were resistant to the development of metastases at multiple organ sites when compared with wild-type controls, both in a tail vein metastasis assay using isogenic melanoma cells and in crosses with the MMTV-neu transgenic mouse model of metastatic breast cancer. Importantly, metastasis from endogenous mammary tumors was suppressed without any enhancement of primary tumorigenesis. Furthermore, aged transgenic mice did not exhibit the severe pathology characteristic of TGF-beta null mice, despite lifetime exposure to the antagonist. The data suggest that in vivo the antagonist may selectively neutralize the undesirable TGF-beta associated with metastasis, while sparing the regulatory roles of TGF-betas in normal tissues. Thus this soluble TGF-beta antagonist has potential for long-term clinical use in the prevention of metastasis.

AN - 71824748; 12068076 AB - The etiology of sporadic Parkinson's disease (PD) remains unknown. Increasing evidence has suggested a role for inflammation in the brain in the pathogenesis of PD. However, it has not been clearly demonstrated whether microglial activation, the most integral part of the brain inflammatory process, will result in a delayed and progressive degeneration of dopaminergic neurons in substantia nigra, a hallmark of PD. We report here that chronic infusion of an inflammagen lipopolysaccharide at 5 ng/h for 2 weeks into rat brain triggered a rapid activation of microglia that reached a plateau in 2 weeks, followed by a delayed and gradual loss of nigral dopaminergic neurons that began at between 4 and 6 weeks and reached 70% by 10 weeks. Further investigation of the underlying mechanism of action of microglia-mediated neurotoxicity using rat mesencephalic neuron-glia cultures demonstrated that low concentrations of lipopolysaccharide (0.1-10 ng/mL)-induced microglial activation and production of neurotoxic factors preceded the progressive and selective degeneration of dopaminergic neurons. Among the factors produced by activated microglia, the NADPH oxidase-mediated release of superoxide appeared to be a predominant effector of neurodegeneration, consistent with the notion that dopaminergic neurons are particularly vulnerable to oxidative insults. This is the first report that microglial activation induced by chronic exposure to inflammagen was capable of inducing a delayed and selective degeneration of nigral dopaminergic neurons and that microglia-originated free radicals play a pivotal role in dopaminergic neurotoxicity in this inflammation-mediated model of PD.

AN - 71819202; 12066962 AB - Matrix metalloproteinases (MMPs) are a family of enzymes involved in degradation of extracellular matrix. An imbalance between MMPs and naturally occurring MMP inhibitors may cause excess extracellular matrix destruction, allowing cancer cells to invade surrounding tissues and metastasize, and permitting angiogenesis to occur. Inhibition of certain key MMPs may prevent angiogenesis, tumor growth, invasion, and metastasis. Gelatinases MMP-2 and MMP-9 are expressed during carcinogenesis and angiogenesis. Synthetic MMP inhibitors were designed to target these enzymes and potentially prevent the tumor growth and metastases associated with cancer.

AN - 71810244; 12058065 AB - The aryl hydrocarbon receptor (AhR or dioxin receptor) is a ligand-activated transcription factor that heterodimerizes with the AhR nuclear translocator (ARNT/HIF-1beta) to form an AhR/ARNT transcription factor complex. This complex binds to specific DNA sites in the regulatory domains of numerous target genes and mediates the biological effects of exogenous ligands. Herein, we have investigated the subcellular distribution of the AhR/ARNT complex in response to ligand stimulation, by using live-cell confocal and high-resolution deconvolution microscopy. We found that unliganded AhR shows a predominantly cytoplasmic diffuse distribution in mouse hepatoma cells. On addition of ligand, AhR rapidly translocates to the nucleus and accumulates in multiple bright foci. Inhibition of transcription prevented the formation of AhR foci. Dual- and triple-immunolabeling experiments, combined with labeling of nascent RNA, showed that the foci are transcription sites, indicating that upon ligand stimulation, AhR is recruited to active transcription sites. The interaction of AhR with ARNT was both necessary and sufficient for the recruitment of AhR to transcription sites. These results indicate that AhR/ARNT complexes are recruited to specific subnuclear compartments in a ligand-dependent manner and that these foci represent the sites of AhR target genes.

AN - 71805648; 12060642 AB - This research investigated the biotransformation of thalidomide by cytochrome P-450 (CYP). We used liver microsomes from humans and/or animals and the recombinant specific CYP isozymes to investigate CYP-mediated metabolism of thalidomide. Thalidomide was biotransformed into 5-hydroxythalidomide (5-OH) and diastereomeric 5'-hydroxythalidomide (5'-OH) by liver microsomes. The human liver microsomes with higher CYP2C19 activity formed more metabolites than those with lower CYP2C19 activity and had less activity in metabolite formations than those from rats. Recombinant human CYP2C19 and rat CYP2C6 isozymes were primarily responsible for forming these metabolites, and the male rat-specific CYP2C11 formed only 5'-OH. 5-OH was subsequently hydroxylated to 5,6-dihydroxythalidomide by CYP2C19, CYP2C9, and CYP1A1 in humans and by CYP2C11, CYP1A1, CYP2C6, and CYP2C12 in rats. Incubations with S-mephenytoin and omeprazole, substrates of CYP2C19, inhibited metabolism by human liver microsomes, supporting the involvement of CYP2C19. alpha-Naphthoflavone, an inhibitor of CYP1A, simultaneously stimulated the 5-OH formation and inhibited cis-5'-OH formation catalyzed by human liver microsomes. The contribution of the CYP2C subfamily was supported by the immunoinhibition study using human liver microsomes. When we used the microsomes from treated rats, the metabolite formations did not increase by inducers for CYP1A, CYP2B, CYP2E, CYP3A, or CYP4A, suggesting that these could not be involved in the main metabolic pathway in rats. We discovered that the polymorphic enzyme CYP2C19 is responsible for 5- and 5'-hydroxylation of thalidomide in humans. In rats, thalidomide was hydroxylated extensively by CYP2C6 as well as the sex-specific enzyme CYP2C11.

AN - 71799803; 12052754 AB - There is no consensus about the role of preoperative radiotherapy (RT) and chemotherapy (CT) in patients with resectable cancer of the distal rectum. This study analyzed the local clinical and pathologic response in patients receiving preoperative RT/CT for rectal cancer. Thirty-two consecutive patients with a palpable adenocarcinoma of the rectum received preoperative RT (45 Gy in 25 fractions over 5 weeks) plus continuous chemotherapy with doxifluridine and leucovorin or 5-fluorouracil by continuous intravenous infusion during RT. Surgery was performed 8 weeks later. The Wilcoxon and chi(2) tests were used for data analysis. Twelve patients had mild gastrointestinal toxicity, only one of whom required interruption of therapy. The tumor shrank to 57.8% of its original size, and at the echoendoscopy (u) there was a 58.7% decrease of the maximum diameter (P <.001). Downstaging from uT3 and uT2 to 2 people [OR = 2.3, 95% CI: 1.3-4.2]), washing/bathing in a pond or ditch (OR = 1.5, 95% CI: 1.0-2.4), and medium (OR = 1.6, 95% CI: 1.3-2.0) and low (OR = 2.3, 95% CI: 1.9-2.9) compared to high village education level, and reduced for never being married or divorced (OR = 0.4, 95% CI: 0.2-1.0). There was also a suggestion that source of drinking water, especially water from a shallow village well might be related to H. pylori seropositivity. There was no evidence of an association between H. pylori prevalence and alcohol or tobacco use, raw fruit and vegetable intake, or individual social class measures. Conclusions The results of this study suggest that person-to-person transmission is the most plausible route of H. pylori infection in this rural Chinese population, but waterborne exposures deserve further investigation.

Gene expression data corresponding to liver samples from rats treated for 24 h with an enzyme inducer (phenobarbital) or a peroxisome proliferator (clofibrate, gemfibrozil or Wyeth 14,643) were subjected to a modified Z-score test to identify gene outliers and a binomial distribution to reduce the probability of detecting genes as differentially expressed by chance. Hierarchical clustering of 238 statistically valid differentially expressed genes partitioned class- specific gene expression signatures into groups that clustered samples exposed to the enzyme inducer or to peroxisome proliferators. Using analysis of variance (ANOVA) and linear discriminant analysis methods we identified single genes as well as coupled gene expression profiles that separated the phenobarbital from the peroxisome proliferator treated samples and discerned the fibrate (gemfibrozil and clofibrate) subclass of peroxisome proliferators. A comparison of genes ranked by ANOVA with genes assessed as significant by mixed linear models analysis [J. Comput. Biol. 8 (2001) 625] or ranked by information gain revealed good congruence with the top 10 genes from each statistical method in the contrast between phenobarbital and peroxisome proliferators expression profiles. We propose building upon a classification regimen comprised of analysis of replicate data, outlier diagnostics and gene selection procedures to utilize cDNA microarray data to categorize subclasses of samples exposed to pharmacologic agents.

Data from sixteen publications were reviewed and analyzed to estimate the transfer coefficient (f sub(hm)*, having units of d L super(-1)). The data on the radioiodine concentration in breast milk were analyzed by two methods: direct numerical integration and integration of a fitted exponential model. In general, the integrated fitted functions were greater. The fitted functions likely better describe the transfer into milk since few data sets sampled mothers' milk near the time of maximum excretion. The derived transfer coefficient values seem to represent two populations. The first group was those individuals who had very low excretions, including those where thyroid and mammary uptake was impaired by the administration of stable iodine or iodinated compounds. The second group included those with much higher excretions. The second group, termed the "normal-excretion" group, had transfers of iodine to milk that were more than ten-fold higher than in the "low-excretion" group. The derived milk transfer coefficient data for the low- and normal-excretion groups fitted to lognormal distributions gave geometric means, (geometric standard deviations), of 0.043 d L super(-1) (2.1, n = 14) and 0.37 d L super(-1) (1.5, n = 12), respectively. Estimates of the effective half-time (time from maximum concentration to half the value) were determined for the low- and normal-excretion groups separately. There was evidence that the effective half-time was longer for the normal- than for the low-excretion group; the geometric mean (and geometric standard deviation) were 12 (1.7) and 8.5 (2.6) h, respectively, though the difference was not statistically significant. The geometric mean times to maximum milk concentration in the low- and normal-excretion groups were nearly identical, 9.4 (3.1) and 9.0 (1.6) h, respectively. The data show that administration of large doses of stable iodine (commonly used to block uptake of iodine into the thyroid) is also an effective means to block radioiodine transfer into milk. Thus, protecting the mother's thyroid also protects the nursing infant. Despite inadequacies of available data describing the transfer of radioiodine to human milk within a healthy population of women, the values of f sub(hm)* provided here are believed to be the best available for use in radiological assessments. These values are particularly applicable to lactating women having normal diets and availability to stable iodine, as in the United States.

Information on past year total physical activity was collected annually through an interview-administered questionnaire from the 1905 men and women enrolled in a randomized dietary intervention study, the Polyp Prevention Trial. Multiple logistic regression analysis was used to examine the association between physical activity and polyp recurrence in up to three years of follow-up from baseline colonoscopy. There were no significant associations between moderate, vigorous, or total physical activity at the start of the trial and overall polyp recurrence in either men or women. Participants who reported consistent vigorous activity throughout the trial period had no significantly reduced risk of polyp recurrence compared to those who reported consistent sedentary activity (OR = 0.8, CI=0.5-1.1). Consistent vigorous activity was also not significantly associated with either advanced or multiple polyps, nor with polyp recurrence at any specific anatomical location in the large bowel. These prospective data suggest that recent physical activity is not associated with polyp recurrence in a three-year period.

We performed a cohort analysis of the 172 subjects who developed pancreatic cancer between 1985 and 1997 (median 10.2 years follow-up) among the 29,048 male smokers, 50-69 years old, who had complete baseline data and participated in the Alpha-Tocopherol, Beta-Carotene Cancer Prevention (ATBC) Study. Cox proportional hazards models were used to estimate multivariable adjusted hazard ratios (HR) and 95% confidence intervals (CI). We observed positive associations between pancreatic cancer risk and self-reported history of diabetes mellitus (HR=2.02, 95% CI 1.17-3.50) and bronchial asthma (HR=2.16, 95% CI 1.17-3.98). Men having combined occupational and leisure activity greater than at sedentary levels had reduced risk for the cancer; for example those with moderate/heavy activity in both settings showed a HR of 0.42 (95% CI 0.22-0.83). There were no significant associations with other self-reported illnesses, total or HDL (high-density lipoprotein) cholesterol, height, weight, or body mass index. Our data suggest that diabetes mellitus and bronchial asthma predict the subsequent risk of developing pancreatic cancer in male smokers, and that greater physical activity may reduce the risk.

We refer to such efforts as 'microevolutionary genomics'. We report the results of comparative analyses of complete intraspecific genome (and proteome) sequences from four bacterial species-Chlamydophila pneumoniae, Escherichia coli, Helicobacter pylori and Neisseria meningitidis. Comparisons of average synonymous (K sub(s)) and nonsynonymous (K sub(a)) substitution rates were used to assess the influence of various biological factors on the rate of protein evolution. For example, E. coli experiences the most intense purifying selection of the species analyzed, and this may be due to the relatively larger population size of this species. In addition, essential genes were shown to be more evolutionarily conserved than nonessential genes in E. coli and duplicated genes have higher rates of evolution than unique genes for all species studied except C. pneumoniae. Different functional categories of genes were shown to evolve at significantly different rates emphasizing the role of category-specific functional constraints in determining evolutionary rates. Finally, functionally characterized genes tend to be conserved between strains, while uncharacterized genes are over-represented among the unique, strain-specific genes. This suggests the possibility that nonessential genes are responsible for driving the evolutionary diversification between strains. [copy ] 2002 Elsevier Science (USA).

To effectively address this important teenage and adult health issue, critical research information and early interventions are needed, yet conducting tobacco research with teen smokers poses substantial challenges, including several ethical dilemmas. This paper reviews some of the ethical issues presented in etiologic and clinical treatment research addressing adolescent smoking. Common problems and possible solutions are presented. Issues of parent/guardian involvement, decision-making ability of teens, the need to maintain confidentiality are discussed, along with the specific problems of recruitment, compensation, and ethical challenges that arise in group treatment settings. Context-specific ethical adjustments and alternative perspectives are likely to be needed if we are to overcome procedural difficulties in conducting teen smoking studies.

Here, we identify directly activated promoters of the overlapping marA , soxS and rob regulon(s) of Escherichia coli by applying informatics, genomics and molecular genetics to microarray data obtained by others. Those studies found that overexpression of marA , or the treatment of cells with salicylate to derepress marA , or treatment with paraquat to induce soxS , resulted in elevated transcription of 153 genes. However, only 27 out of the promoters showed increased transcription under at least two of the aforementioned conditions and eight of those were previously known to be directly activated. A computer algorithm was used to identify potential activator binding sites located upstream of the remaining 19 promoters of this subset, and conventional genetic and biochemical approaches were applied to test whether these sites are critical for activation by the homologous MarA, SoxS and Rob transcriptional activators. Only seven out of the 19 promoters were found to be activated when fused to lacZ and tested as single lysogens. All seven contained an essential activator binding site. The remaining promoters were insensitive to stimulation by the inducers suggesting that the great majority of elevated microarray transcripts either were misidentified or resulted from indirect effects requiring sequences outside of the promoter region. We estimate that the total number of directly activated promoters in the regulon is less than 40.

Chemotherapy is effective in reducing tumor burden in a majority of patients, however, only approximately 20% of advanced disease patients will ultimately survive tumor free, and further treatment options are needed. Continuing advances in immunology make immunotherapy a promising area for future research. The design of immunotherapy strategies for ovarian cancer requires an understanding of the immune microenvironment of the peritoneal cavity, which is frequently involved with ovarian cancer metastases and is the site of its most devastating effects. Immunotherapy approaches for ovarian cancer include locoregional and systemic cytokine therapies, prophylactic and therapeutic vaccines, and adoptive immunotherapy strategies. This review will summarize previous clinical trials as well as future directions for research. Further progress in T-cell specific immune responses will require the identification of specific ovarian cancer antigens that are processed and presented on the surface of tumor cells in the context of specific HLA molecules. In addition, a more detailed understanding of functional relations between the peritoneal microenvironment and the metastatic process is required.

The chemotherapy-conditioning schedule that induced transient lymphopenia consisted of cyclophosphamide (30 or 60 mg/kg per day for 2 days) followed by fludarabine (25 mg/m super(2) per day for 5 days). Immunotherapy for all patients consisted of in vitro expanded, tumor-reactive, autologous T-cell clones selected for high avidity recognition of melanoma antigens. Cohorts of three to six patients each received either no interleukin (IL)-2, low-dose IL-2 (72,000 IU/kg intravenously three times a day to a maximum of 15 doses), or high-dose IL-2 (720,000 IU/kg intravenously three times a day for a maximum of 12 doses). The toxicities associated with this treatment were transient and included neutropenia and thrombocytopenia that resolved in all patients. High dose intravenous IL-2 was better tolerated by patients after chemotherapy than during previous immunotherapy cycles without chemotherapy. No patient exhibited an objective clinical response to treatment, although five patients demonstrated mixed responses or transient shrinkage of metastatic deposits. This study established a nonmyeloablative-conditioning regimen that could be safely administered in conjunction with adoptive T-cell transfer and IL-2 in patients with metastatic melanoma.

Furthermore, particular clinical relevance was attributed to gp100/pMel17 based on the impression that the adoptive transfer of gp100-recognizing TIL was associated with clinical responses in a small group of patients. However, the actual frequency of specific T cells for these melanoma differentiation antigens has never been directly enumerated in ex vivo or in vitro expanded TIL cultures. Here, we enumerated melanoma differentiation antigen-specific T-cell precursor frequency in TIL using tetrameric HLA/epitope complexes, functionally characterizing their responsiveness to cognate epitope by cytokine release assay. T-cell precursor frequencies were enumerated in 11 fresh-tumor preparations and 17 TIL adoptively transferred into patients bearing HLA-A*0201. MART-1 or gp100-specific T cells could be detected respectively in 5 and 2 of the 11 fresh preparations and in 5 and 2 of the 17 adoptively transferred TIL. With one exception, melanoma differentiation antigen-specific T-cell precursor frequency in fresh material and TIL ranged between 5,000 to 21,000/10 super(6) CD8 super(+) T cells. T-cell precursor frequency was not significantly higher in TIL whose administration was associated with clinical response. These data provide direct enumeration of MART-1/MelanA and gp100/pMel17 reactivity ex vivo and in vitro in the context of HLA-A*0201.

Subcutaneous Flt3L administration has been shown to effectively manage some murine cancers and in humans, to lead to an increase in peripheral blood monocyte and dendritic cell (DC) counts. In the current study, we determined the effects of Flt3L therapy on patients with melanoma and renal cancer, and in particular, if Flt3L could be used either by enhancing the immunization of patients with melanoma to tumor antigen peptides in vivo, or by mobilizing DC precursors to allow the production of larger numbers of cultured DC. Flt3 ligand administration resulted in a 19-fold increase in DC counts in the peripheral blood of patients. The DC generated in vivo appeared only partially activated, expressing increased levels of CD86, CD33, and major histocompatibility complex class II, but no or low levels of CD80 and CD83. This partial activation may account for the lack of enhanced immune responses to melanoma antigens and absence of clinical responses in the patients even in combination with antigen immunization. Flt3 ligand administration did result, however, in a 7-fold increased yield of monocytes per liter of blood from leukapheresed patients. Dendritic cells were as readily generated from monocytes collected before and after Flt3L therapy, and they stimulated allogeneic T-cell proliferation in a mixed leukocyte reaction to a similar magnitude. Thus, the use of Flt3L may be an important method to mobilize DC precursors to allow patient therapy with larger numbers of cultured DC.

Stomach cancer mortality rates are much higher in Japan than in the U.S., making the applicability of LSS findings to the U.S. population uncertain. A unique cohort of U.S. patients who were irradiated for peptic ulcer to control gastric secretion provides a different perspective on risk. Cancer mortality data were analyzed and relative risks estimated for 3719 subjects treated by radiotherapy (mean stomach dose 14.8 Gy) and/or by surgery and medication during the period 1936-1965 and followed through 1997 (average 25 years). Compared to the U.S. rates, stomach cancer mortality was significantly increased for irradiated and nonirradiated patients (observed/expected = 3.20 and 1.52, respectively). We observed strong evidence of exposure-related excess mortality from cancer of the stomach (RR 2.6, 95% CI 1.3, 5.1), pancreas (RR 2.7, 95% CI 1.5, 5.1), and lung (RR 1.5, 95% CI 1.1, 2.1), with commensurate radiation dose responses in analyses that included nonexposed patients. However, the dose responses for these cancers were not significant when restricted to exposed patients. Our excess relative risk per gray estimate of 0.20 at doses ,10 Gy (95% CI 0, 0.73) is consistent with the estimate of 0.24 (95% CI 0.10, 0.40) obtained from the LSS study with the linear model.

All animals received a daily saline injection for 6 days prior to methamphetamine treatment. We have found that, similar to c-fos activation, NGFI-B mRNA levels were significantly increased 2 h after methamphetamine treatment and returned to basal levels 6 h later. Induction of NGFI-B mRNA levels by methamphetamine was highest in central striatum as compared to the dorsomedial distribution pattern observed in control animals. After acute methamphetamine treatment, the distribution pattern of NGFI-B mRNA upregulation was very similar to that of methamphetamine induced c-Fos immunoreactivity. However, co-localization studies with c-Fos immunoreactivity showed that not all NGFI-B-positive cells contained c-Fos after methamphetamine treatment. Forty-five percent of all NGFI-B mRNA expressing neurons contained c-Fos immunoreactivity in the dorsomedial striatum as compared to 60% in central and 35% in ventrolateral striatum. This study provides a detailed description of the differential spatial and temporal modulation of NGFI-B and c-Fos expression in the striatum by acute methamphetamine treatment over time.

Two major domains of the 739-residue Rel sub(Seq) protein are defined by limited proteolytic digestion. In vitro assays of the purified N- terminal half-protein reveal synthesis of (p)ppGpp by an ATP-GTP 3'- pyrophosphotransferase as well as an ability to degrade (p)ppGpp by a Mn super(2+)- dependent 3'-pyrophosphohydrolase. Removal of the C-terminal half-protein has reciprocal regulatory effects on the activities of the N-terminal half-protein. Compared to the full-length protein, deletion activates (p)ppGpp synthesis specific activity about 12-fold and simultaneously inhibits (p)ppGpp degradation specific activity about 150-fold to shift the balance of the two activities in favor of synthesis. Cellular (p)ppGpp accumulation behavior is consistent with these changes. The bifunctional N-terminal half-protein can be further dissected into overlapping monofunctional subdomains, since purified peptides display either degradation activity (residues 1 to 224) or synthetic activity (residues 79 to 385) in vitro. These assignments can also apply to RelA and SpoT. The ability of Rel sub(Seq) to mediate (p)ppGpp accumulation during amino acid starvation in S. equisimilis is absent when the protein is expressed ectopically in Escherichia coli. Fusing the N-terminal half of Rel sub(Seq) with the C-terminal domain of RelA creates a chimeric protein that restores the stringent response in E. coli by inhibiting unregulated degradation and restoring regulated synthetic activity. Reciprocal intramolecular regulation of the dual activities may be a general intrinsic feature of Rel/Spo homolog proteins.

Mice were injected with plasmid expression vectors encoding HIV Env with modifications in regions that might affect this response. Elimination of conserved glycosylation sites did not substantially enhance humoral or cytotoxic-T-lymphocyte (CTL) immunity. In contrast, a modified gp140 with different COOH-terminal mutations intended to mimic a fusion intermediate and stabilize trimer formation enhanced humoral immunity without reducing the efficacy of the CTL response. This mutant, with deletions in the cleavage site, fusogenic domain, and spacing of heptad repeats 1 and 2, retained native antigenic conformational determinants as defined by binding to known monoclonal antibodies or CD4, oligomer formation, and virus neutralization in vitro. Importantly, this modified Env, gp140[Delta]CFI, stimulated the antibody response to native gp160 while it retained its ability to induce a CTL response, a desirable feature for an AIDS vaccine.

Because of its ability to enhance the solubility and promote the proper folding of its fusion partners, Escherichia coli maltose-binding protein (MBP) is a particularly useful affinity tag. However, not all MBP fusion proteins bind efficiently to amylose resin, and even when they do it is usually not possible to obtain a sample of adequate purity after a single affinity step. To address this problem, we endeavored to incorporate supplemental affinity tags within the framework of an MBP fusion protein. We show that both the nature of the supplemental tags and their location can influence the ability of MBP to promote the solubility of its fusion partners. The most promising configurations for high-throughput protein expression and purification appear to be a fusion protein with a biotin acceptor peptide (BAP) on the N-terminus of MBP and/or a hexahistidine tag (His-tag) on the C-terminus of the passenger protein.

AN - 71720208; 11912190 AB - Neurogranin (Ng) is a brain-specific, postsynaptically located protein kinase C (PKC) substrate, highly expressed in the cortex, hippocampus, striatum, and amygdala. This protein is a Ca(2+)-sensitive calmodulin (CaM)-binding protein whose CaM-binding affinity is modulated by phosphorylation and oxidation. To investigate the role of Ng in neural function, a strain of Ng knockout mouse (KO) was generated. Previously we reported (Pak, J. H., Huang, F. L., Li, J., Balschun, D., Reymann, K. G., Chiang, C., Westphal, H., and Huang, K.-P. (2000) Proc. Natl. Acad. Sci. U. S. A. 97, 11232-11237) that these KO mice displayed no obvious neuroanatomical abnormality, but exhibited deficits in learning and memory and activation of Ca(2+)/CaM-dependent protein kinase II. In this report, we analyzed several downstream phosphorylation targets in phorbol 12-myristate 13-acetate- and forskolin-treated hippocampal slices from wild type (WT) and KO mice. Phorbol 12-myristate 13-acetate caused phosphorylation of Ng in WT mice and promoted the translocation of PKC from the cytosolic to the particulate fractions of both the WT and KO mice, albeit to a lesser extent in the latter. Phosphorylation of downstream targets, including mitogen-activated protein kinases, 90-kDa ribosomal S6 kinase, and the cAMP response element binding protein (CREB) was significantly attenuated in KO mice. Stimulation of hippocampal slices with forskolin also caused greater stimulation of protein kinase A (PKA) in the WT as compared with those of the KO mice. Again, phosphorylation of the downstream targets of PKA was attenuated in the KO mice. These results suggest that Ng plays a pivotal role in regulating both PKC- and PKA-mediated signaling pathways, and that the deficits in learning and memory of spatial tasks detected in the KO mice may be the result of defects in the signaling pathways leading to the phosphorylation of CREB.

AN - 71719362; 11919199 AB - Sulfolobus solfataricus DNA polymerase IV (Dpo4) is a member of the Y family of DNA polymerases whose crystal structure has recently been solved. As a model for other evolutionarily conserved Y family members that perform translesion DNA synthesis and have low fidelity, we describe here the base substitution and frameshift fidelity of DNA synthesis by Dpo4. Dpo4 generates all 12 base-base mismatches at high rates, 11 of which are similar to those of its human homolog, DNA polymerase kappa. This result is consistent with the Dpo4 structure, implying lower geometric selection for correct base pairs. Surprisingly, Dpo4 generates C.dCMP mismatches at an unusually high average rate and preferentially at cytosine flanked by 5'-template guanine. Dpo4 also has very low frameshift fidelity and frequently generates deletions of even noniterated nucleotides, especially cytosine flanked by a 5'-template guanine. Both unusual features of error specificity suggest that Dpo4 can incorporate dNTP precursors when two template nucleotides are present in the active site binding pocket.

AN - 72799502; 12509239 AB - Our understanding of the molecular mechanisms of error-prone lesion bypass has changed dramatically in the past few years. The concept that the key participants in the mutagenic process were accessory proteins that somehow modified the ability of the cell's main replicase to facilitate bypass of normally blocking lesions has been replaced with one in which the replicase is displaced by a polymerase specialized in lesion bypass. The participants in this process remain the same, only their function has been reassigned. What was once known as the UmuC/DinB/Rev1/Rad30 superfamily of mutagenesis proteins, is now known as the Y-family of DNA polymerases. Quite remarkably, within the space of 3 years, the field has advanced from the initial discovery of intrinsic polymerase function, to the determination of the tertiary structures of several Y-family DNA polymerases.A key to determining the biochemical properties of each DNA polymerase is through structure-function studies that result in the site-specific substitution of particular amino acids at critical sites within each DNA polymerase. However, we should not forget the power of genetic selection that allows us to identify residues within each polymerase that are generated by "random mutagenesis" and which are important for both a gain or loss of function in vivo. In this review, we discuss the structural ramifications of several missense mutations previously identified in various Y-family DNA polymerase and speculate on how each amino acid substitution might modify the enzymatic activity of the respective polymerase or possibly perturb protein-protein interactions necessary for efficient translesion replication in vivo.

However, during the gene transfer, they may alter the principal function and local environment of transfected cells. Increasing evidence exists for a selective adrenotropism of adenovirus during infections and gene transfer. Therefore, using bovine adrenocortical cells in primary culture, we analyzed the influence of different adenoviral deletion mutants on cell morphology and physiology. Transfection of cells with an E1/E3-deleted adenoviral vector, engineered to express a modified form of the Aequorea victoria green fluorescent protein, was highly efficient, as documented by fluorescent microscopy. Ultrastructural analysis, however, demonstrated nuclear fragmentation and mitochondrial alterations in addition to intranuclear viral particles. Basal secretion of 17-OH-progesterone, 11-deoxycortisol cortisol was significantly increased by E1/E3-deleted vectors; yet, the corticotropin-stimulated release of these steroids was decreased. Interestingly, neither purified viral capsids nor E3/E4-deleted adenoviral mutants altered basal and stimulated steroidogenesis of adrenocortical cells. An intact adrenal response is crucial for adaptation to stress and survival. Therefore, the implications of our findings need to be considered in patients with adenoviral infections and those undergoing clinical studies using adenoviral gene transfer. At the same time, the high level of transfection in adrenocortical cells might make appropriately modified adenoviral vectors suitable for gene therapy of adrenocortical carcinomas with poor prognosis.

Unexpectedly, an isogenic sic-negative mutant adhered to human epithelial cells significantly better than the wild-type parental strain. Purified Sic inhibited the adherence of a sic negative serotype M1 mutant and of non-Sic-producing GAS strains to human epithelial cells. Sic was rapidly internalized by human epithelial cells, inducing cell flattening and loss of microvilli. Ezrin and moesin, human proteins that functionally link the cytoskeleton to the plasma membrane, were identified as Sic-binding proteins by affinity chromatography and matrix-assisted laser desorption/ionization time-of-flight mass spectrometry analysis. Sic colocalized with ezrin inside epithelial cells and bound to the F-actin-binding site region located in the carboxyl terminus of ezrin and moesin. Synthetic peptides corresponding to two regions of Sic had GAS adherence-inhibitory activity equivalent to mature Sic and inhibited binding of Sic to ezrin. In addition, the sic mutant was phagocytosed and killed by human polymorphonuclear leukocytes significantly better than the wild-type strain, and Sic colocalized with ezrin in discrete regions of polymorphonuclear leukocytes. The data suggest that binding of Sic to ezrin alters cellular processes critical for efficient GAS contact, internalization, and killing. Sic enhances bacterial survival by enabling the pathogen to avoid the intracellular environment. This process contributes to the abundance of M1 GAS in human infections and their ability to cause epidemics.

AN - 71704951; 11880385 AB - The Ca(2+) receptor, a member of the family 3 of G protein-coupled receptors (GPCR), responds not only to its primary physiological ligand Ca(2+) but also to other di- and trivalent metals (Mg(2+), Gd(3+)) and the organic polycations spermine and poly-l-Arginine. As has been found for other family 3 GPCRs, the large amino-terminal extracellular domain (ECD) of the Ca(2+) receptor is the primary Ca(2+) binding domain. To examine how the signal is propagated from the ECD to the seven-transmembrane core domain (7TM) we constructed a Ca(2+) receptor mutant (T903-Rhoc) lacking the entire ECD but containing the 7TM. We have found that this structure initiates signaling in human embryonic kidney (HEK) 293 cells stably expressing the construct. One or more cation recognition sites are also located within the 7TM. Not only Ca(2+), but also several other Ca(2+) receptor-specific agonists, Mg(2+), Gd(3+), spermine, and poly-l-Arginine, can activate T903-Rhoc truncated receptor-initiated phosphoinositide hydrolysis in HEK 293 cells. The phenylalkylamine compound, NPS 568, identified as a positive allosteric modulator of the Ca(2+) receptor can selectively potentiate the actions of Ca(2+) and other polycationic agonists on the T903-Rhoc receptor. Similarly, organic polycations synergistically activate T903-Rhoc with di- and trivalent metals. Alanine substitution of all the acidic residues in the second extracellular loop of the T903-Rhoc receptor significantly impairs activation by metal ions and organic polycations in the presence of NPS 568 but not the synergistic activation of Ca(2+) with poly-l-Arginine. These data indicate that although the ECD has been thought to be the main determinant for Ca(2+) recognition, the 7TM core of the Ca(2+) receptor contains activating site(s) recognizing Ca(2+) and Gd(3+) as well as the allosteric modulators NPS 568 and organic polycations that may play important roles in the regulation of receptor activation.

AN - 71696771; 11891221 AB - Ligand recognition has been extensively explored in G protein-coupled A(1), A(2A), and A(2B) adenosine receptors but not in the A(3) receptor, which is cerebroprotective and cardioprotective. We mutated several residues of the human A(3) adenosine receptor within transmembrane domains 3 and 6 and the second extracellular loop, which have been predicted by previous molecular modeling to be involved in the ligand recognition, including His(95), Trp(243), Leu(244), Ser(247), Asn(250), and Lys(152). The N250A mutant receptor lost the ability to bind both radiolabeled agonist and antagonist. The H95A mutation significantly reduced affinity of both agonists and antagonists. In contrast, the K152A (EL2), W243A (6.48), and W243F (6.48) mutations did not significantly affect the agonist binding but decreased antagonist affinity by approximately 3-38-fold, suggesting that these residues were critical for the high affinity of A(3) adenosine receptor antagonists. Activation of phospholipase C by wild type (WT) and mutant receptors was measured. The A(3) agonist 2-chloro-N(6)-(3-iodobenzyl)-5'-N-methylcarbamoyladenosine stimulated phosphoinositide turnover in the WT but failed to evoke a response in cells expressing W243A and W243F mutant receptors, in which agonist binding was less sensitive to guanosine 5'-gamma-thiotriphosphate than in WT. Thus, although not important for agonist binding, Trp(243) was critical for receptor activation. The results were interpreted using a rhodopsin-based model of ligand-A(3) receptor interactions.

Post-exposure protection of monkeys against rabies virus by DNA vaccination has not been attempted. Presumably, post-exposure experiments have not been undertaken because neutralizing antibody is usually slow to be induced after DNA vaccination. In this study, we initially attempted to accelerate the induction of neutralizing antibody by varying the route and site of DNA vaccination and booster frequency. Gene gun (GG) vaccinations above axillary and inguinal lymph nodes or in ear pinnae generated higher levels of neutralizing antibody than intradermal (ID) needle vaccinations in the pinnae. Concurrent GG booster vaccinations above axillary and inguinal lymph nodes and in ear pinnae, 3 days after primary vaccination, accelerated detectable neutralizing antibody. GG booster vaccinations also resulted in higher neutralizing antibody levels and increased the durability of this response. Post-exposure vaccination with DNA or the human diploid cell vaccine (HDCV), in combination with an one-time treatment with human rabies immune globulin (HRIG), protected 50 and 75% of the monkeys, respectively, as compared to 75% mortality of the controls. These data will be useful for the refinement, development, and implementation of future pre- and post-exposure rabies DNA vaccination studies.

We investigated a new route of intranasal-associated lymphoid tissue (intra-NALT) administration of antigens to circumvent the antigen transportation barrier. A comparative study was carried out on mice administered with killed whole cells of Moraxella catarrhalis strain 25238 plus cholera toxin (CT) by intra-NALT injection and nasal inoculation. Both routes induced significant elevations of several isotype antibodies against strain 25238 in saliva, lung lavage, and serum as measured by an enzyme-linked immunosorbent assay (ELISA). Most of these antibodies were paralleled by the numbers of their corresponding antibody forming cells in mucosal or systemic lymphoid tissues. However, intra-NALT injection elicited higher levels of immunoglobulin (Ig) A and IgG in saliva, IgA and IgG in lung lavage, and IgG and IgM in sera than nasal inoculation (P less than or equal to 0.05). In addition, both routes generated significant reductions of bacteria in lungs following an aerosol challenge with strain 25238 in a mouse model of pulmonary clearance. Once again, intra-NALT route showed better bacterial clearance in mouse lungs than nasal inoculation (P < 0.01). These results demonstrate that intra-NALT administration of antigens is a convenient and effective route for mucosal immunization that elicits improved mucosal and systemic immunity. This new route can be used as a model to study mucosal antigens or vaccine candidates for antigen activation and interaction with the NALT that is one of major inductive sites for common mucosal immune system.

AN - 71712795; 11992417 AB - The successful use of tissue- or tumor-selective promoters in targeted gene therapy for cancer depends on high and selective activity. Tg is a thyroid-specific protein that is expressed in the normal thyroid and a majority of thyroid tumors. In the present study, we show, using a luciferase reporter assay, that a construct containing the putative Tg promoter and enhancer is active in 4 thyroid carcinoma cell lines (including 2 anaplastic thyroid carcinoma cell lines) and not in 5 cancer cell lines arising from nonthyroid tissues. Furthermore, both the activity and the specificity of this construct were increased by pretreatment with 8-Br-cAMP and the histone deacetylase inhibitor depsipeptide (FR901228). Expression of thymidine kinase in thyroid cancer cells infected with a recombinant adenovirus (Ad) carrying a Tg enhancer/promoter-thymidine kinase expression cassette (AdTg enhancer/promoter-TK) correlated with the level of Tg enhancer/promoter activity in these cells. Under similar conditions, TK expression was not observed in cancer cell lines arising from nonthyroid tissues. Cells infected with AdTg enhancer/promoter-TK demonstrated preferential GCV sensitivity, with up to a 100,000-fold increase in GCV sensitivity in thyroid cancer cell lines compared to cancer cell lines of nonthyroid origin. The construct described herein can be used to selectively target thyroid cancer cells, and its expression can be modulated to further increase its specificity and selectivity, especially in anaplastic thyroid carcinoma cells, using 8-Br-cAMP and depsipeptide.

AN - 71705790; 12021305 AB - Transforming growth factor (TGF)-beta is the prototype in a family of secreted proteins that act in autocrine and paracrine pathways to regulate cell development and function. Normal cells typically coexpress TGF-beta receptors and one or more isoforms of TGF-beta, thus the synthesis and secretion of TGF-beta as an inactive latent complex is considered an essential step in regula-ting the activity of this pathway. To determine whether intracellular activation of TGF-beta results in TGF-beta ligand-receptor interactions within the cell, we studied pristane-induced plasma cell tumors (PCTs). We now demonstrate that active TGF-beta1 in the PCT binds to intracellular TGF-beta type II receptor (TbetaRII). Disruption of the expression of TGF-beta1 by antisense TGF-beta1 mRNA restores localization of TbetaRII at the PCT cell surface, indicating a ligand-induced impediment in receptor trafficking. We also show that retroviral expression of a truncated, dominant-negative TbetaRII (dnTbetaRII) effectively competes for intracellular binding of active ligand in the PCT and restores cell surface expression of the endogenous TbetaRII. Analysis of TGF-beta receptor-activated Smad2 suggests the intracellular ligand-receptor complex is not capable of signaling. These data are the first to demonstrate the formation of an intracellular TGF-beta-receptor complex, and define a novel mechanism for modulating the TGF-beta signaling pathway.

In mammals, including humans, inorganic arsenicals often undergo methylation, forming compounds such as dimethyarsinic acid (DMA). Recent evidence indicates DMA is a complete carcinogen in rodents while evidence for inorganic arsenicals as carcinogens in rodents remains equivocal. Thus, we studied the molecular mechanisms of in vitro cytolethality of DMA compared to that of the trivalent inorganic arsenical, sodium arsenite, using a rat liver epithelial cell line (TRL 1215). Arsenite was very cytotoxic in these cells (LC sub(50) = 35 mu M after 48 h of exposure). With arsenite exposure, most dead cells showed histological and biochemical evidence of necrosis. Arsenite cytotoxicity increased markedly when cellular GSH was depleted with the glutathione synthase inhibitor, L-buthionine-[S,R]-sulfoximine (BSO). In contrast, DMA was nearly 3 orders of magnitude less cytotoxic (LC sub(50) = 1.5 mM) although evidence showed the predominating form of death was apoptosis. Surprisingly, GSH depletion actually decreased DMA-induced apoptosis. A glutathione scavenger, diethyl maleate (DEM), and a glutathione reductase inhibitor, carmustine, also prevented DMA-induced apoptosis. These data indicate that DMA requires intracellular GSH to induce apoptosis. Ethacrynic acid (EA), an inhibitor of glutathione S-transferase (GST) that catalyzes GSH-substrate conjugation, acivicin, an inhibitor of gamma -glutamyltranspeptidase (GGT) which catalyzes the initial breakdown of GSH-substrate conjugates, and aminooxyacetic acid (AOAA), an inhibitor of beta -lyase which catalyzes the final breakdown of GSH-substrate conjugates, all were effective in suppressing DMA-induced apoptosis. These findings indicate that DMA likely is conjugated in some form with GSH, and that it is this conjugate that induces apoptosis during subsequent metabolic reactions.

Recommendations of the Panel on Clinical Practices for Treatment of HIV. AN - 71713138; 12027060 AB - The availability of an increasing number of antiretroviral agents and the rapid evolution of new information has introduced substantial complexity into treatment regimens for persons infected with human immunodeficiency virus (HIV). In 1996, the Department of Health and Human Services and the Henry J. Kaiser Family Foundation convened the Panel on Clinical Practices for the Treatment of HIV to develop guidelines for clinical management of HIV-infected adults and adolescents (CDC. Report of the NIH Panel To Define Principles of Therapy of HIV Infection and Guidelines for the use of antiretroviral agents in HIV-infected adults and adolescents. MMWR 1998;47[RR-5]:1-41). This report, which updates the 1998 guidelines, addresses 1) using testing for plasma HIV ribonucleic acid levels (i.e., viral load) and CD4+ T cell count; 2) using testing for antiretroviral drug resistance; 3) considerations for when to initiate therapy; 4) adherence to antiretroviral therapy; 5) considerations for therapy among patients with advanced disease; 6) therapy-related adverse events; 7) interruption of therapy; 8) considerations for changing therapy and available therapeutic options; 9) treatment for acute HIV infection; 10) considerations for antiretroviral therapy among adolescents; 11) considerations for antiretroviral therapy among pregnant women; and 12) concerns related to transmission of HIV to others. Antiretroviral regimens are complex, have serious side effects, pose difficulty with adherence, and carry serious potential consequences from the development of viral resistance because of nonadherence to the drug regimen or suboptimal levels of antiretroviral agents. Patient education and involvement in therapeutic decisions is critical. Treatment should usually be offered to all patients with symptoms ascribed to HIV infection. Recommendations for offering antiretroviral therapy among asymptomatic patients require analysis of real and potential risks and benefits. Treatment should be offered to persons who have 55,000 copies/mL (by b-deoxyribonucleic acid [bDNA] or reverse transcriptase-polymerase chain reaction [RT-PCR] assays). The recommendation to treat asymptomatic patients should be based on the willingness and readiness of the person to begin therapy; the degree of existing immunodeficiency as determined by the CD4+ T cell count; the risk for disease progression as determined by the CD4+ T cell count and level of plasma HIV RNA; the potential benefits and risks of initiating therapy in an asymptomatic person; and the likelihood, after counseling and education, of adherence to the prescribed treatment regimen. Treatment goals should be maximal and durable suppression of viral load, restoration and preservation of immunologic function, improvement of quality of life, and reduction of HIV-related morbidity and mortality. Results of therapy are evaluated through plasma HIV RNA levels, which are expected to indicate a 1.0 log10 decrease at 2-8 weeks and no detectable virus (<50 copies/mL) at 4-6 months after treatment initiation. Failure of therapy at 4-6 months might be ascribed to nonadherence, inadequate potency of drugs or suboptimal levels of antiretroviral agents, viral resistance, and other factors that are poorly understood. Patients whose therapy fails in spite of a high level of adherence to the regimen should have their regimen changed; this change should be guided by a thorough drug treatment history and the results of drug-resistance testing. Because of limitations in the available alternative antiretroviral regimens that have documented efficacy, optimal changes in therapy might be difficult to achieve for patients in whom the preferred regimen has failed. These decisions are further confounded by problems with adherence, toxicity, and resistance. For certain patients, participating in a clinical trial with or without access to new drugs or using a regimen that might not achieve complete suppression of viral replication might be preferable. Because concepts regarding HIV management are evolving rapidly, readers should check regularly for additional information and updates at the HIV/AIDS Treatment Information Service website (http://www.hivatis.org).

AN - 71681860; 11884400 AB - The peroxisome proliferation-activated receptor gamma (PPARgamma) is expressed in many cell types including mammary epithelium, ovary, macrophages, and B- and T-cells. PPARgamma has an anti-proliferative effect in pre-adipocytes and mammary epithelial cells, and treatment with its ligands reduced the progression of carcinogen-induced mammary tumors in mice. Because PPARgamma-null mice die in utero it has not been possible to study its role in development and tumorigenesis in vivo. To investigate whether PPARgamma is required for the establishment and physiology of different cell types, a cell-specific deletion of the gene was carried out in mice using the Cre-loxP recombination system. We deleted the PPARgamma gene in mammary epithelium using WAP-Cre transgenic mice and in epithelial cells, B- and T-cells, and ovary cells using MMTV-Cre mice. The presence of PPARgamma was not required for functional development of the mammary gland during pregnancy and for the establishment of B- and T-cells. In addition, no increase in mammary tumors was observed. However, loss of the PPARgamma gene in oocytes and granulosa cells resulted in impaired fertility. These mice have normal populations of follicles, they ovulate and develop corpora lutea. Although progesterone levels are decreased and implantation rates are reduced, the exact cause of the impaired fertility remains to be determined.

AN - 71680892; 11882652 AB - Amyloid beta-peptide (Abeta) is implicated as the toxic agent in Alzheimer's disease and is the major component of brain amyloid plaques. In vitro, Abeta causes cell death, but the molecular mechanisms are unclear. We analyzed the early signaling mechanisms involved in Abeta toxicity using the SH-SY5Y neuroblastoma cell line. Abeta caused cell death and induced a 2- to 3-fold activation of JNK. JNK activation and cell death were inhibited by overexpression of a dominant-negative SEK1 (SEK1-AL) construct. Butyrolactone I, a cdk5 inhibitor, had an additional protective effect against Abeta toxicity in these SEK1-AL-expressing cells suggesting that cdk5 and JNK activation independently contributed to this toxicity. Abeta also weakly activated ERK and Akt but had no effect on p38 kinase. Inhibitors of ERK and phosphoinositide 3-kinase (PI3K) pathways did not affect Abeta-induced cell death, suggesting that these pathways were not important in Abeta toxicity. Insulin-like growth factor I protected against Abeta toxicity by strongly activating ERK and Akt and blocking JNK activation in a PI3K-dependent manner. Pertussis toxin also blocked Abeta-induced cell death and JNK activation suggesting that G(i/o) proteins were upstream activators of JNK. The results suggest that activation of the JNK pathway and cdk5 may be initial signaling cascades in Abeta-induced cell death.

AN - 71680708; 11884392 AB - Estrogen sulfotransferase (EST) transfers the sulfate group from 3'-phosphoadenosine 5'-phosphosulfate (PAPS) to estrogenic steroids. Here we report the crystal structure of human EST (hEST) in the context of the V269E mutant-PAPS complex, which is the first structure containing the active sulfate donor for any sulfotransferase. Superimposing this structure with the crystal structure of hEST in complex with the donor product 3'-phosphoadenosine 5'-phosphate (PAP) and the acceptor substrate 17beta-estradiol, the ternary structure with the PAPS and estradiol molecule, is modeled. These structures have now provided a more complete view of the S(N)2-like in-line displacement reaction catalyzed by sulfotransferases. In the PAPS-bound structure, the side chain nitrogen of the catalytic Lys(47) interacts with the side chain hydroxyl of Ser(137) and not with the bridging oxygen between the 5'-phosphate and sulfate groups of the PAPS molecule as is seen in the PAP-bound structures. This conformational change of the side chain nitrogen indicates that the interaction of Lys(47) with Ser(137) may regulate PAPS hydrolysis in the absences of an acceptor substrate. Supporting the structural data, the mutations of Ser(137) to cysteine and alanine decrease gradually k(cat) for PAPS hydrolysis and transfer activity. Thus, Ser(137) appears to play an important role in regulating the side chain interaction of Lys(47) with the bridging oxygen between the 5'-phosphate and the sulfate of PAPS.

AN - 71798697; 12054463 AB - The nitroxyl (HNO) donor Angeli's salt (Na(2)N(2)O(3); AS) is cytotoxic in vitro, inducing double strand DNA breaks and base oxidation, yet may have pharmacological application in the treatment of cardiovascular disease. The chemical profiles of AS and synthetic peroxynitrite (ONOO(-)) in aerobic solution were recently compared, and AS was found to form a distinct reactive intermediate. However, similarities in the chemical behavior of the reactive nitrogen oxide species (RNOS) were apparent under certain conditions. Buffer composition was found to have a significant and unexpected impact on the observed chemistry of RNOS, and varied buffer conditions were utilized to further distinguish the chemical profiles elicited by the RNOS donors AS and synthetic ONOO(-). Addition of HEPES to the assay buffer significantly quenched oxidation of dihydrorhodamine (DHR), hydroxylation of benzoic acid (BA), and DNA damage by both AS and ONOO(-), and oxidation and nitration of hydroxyphenylacetic acid by ONOO(-). Additionally, H(2)O(2) was produced in a concentration-dependent manner from the interaction of HEPES with both the donor intermediates. Interestingly, clonogenic survival was not affected by HEPES, indicating that H(2)O(2) is not a contributing factor to in vitro cytotoxicity of AS. Variation in RNOS reactivity was dramatic with significantly higher relative affinity for the AS intermediate toward DHR, BA, DNA, and HEPES and increased production of H(2)O(2). Further, AS reacted to a significantly greater extent with the unprotonated amine form of HEPES while the interaction of ONOO(-) with HEPES was pH-independent. Addition of bicarbonate only altered ONOO(-) chemistry. This study emphasizes the importance of buffer composition on chemical outcome and thus on interpretation and provides further evidence that ONOO(-) is not an intermediate formed between the reaction of O(2) and HNO produced by AS.

AN - 71745651; 12023305 AB - The protein kinase GCN2 is activated in amino acid-starved cells on binding of uncharged tRNA to a histidyl-tRNA synthetase (HisRS)-related domain. We isolated two point mutations in the protein kinase (PK) domain, R794G and F842L, that permit strong kinase activity in the absence of tRNA binding. These mutations also bypass the requirement for ribosome binding, dimerization, and association with the GCN1/GCN20 regulatory complex, suggesting that all of these functions facilitate tRNA binding to wild-type GCN2. While the isolated wild-type PK domain was completely inert, the mutant PK was highly active in vivo and in vitro. These results identify an inhibitory structure intrinsic to the PK domain that must be overcome on tRNA binding by interactions with a regulatory region, most likely the N terminus of the HisRS segment. As Arg 794 and Phe 842 are predicted to lie close to one another and to the active site, they may participate directly in misaligning active site residues. Autophosphorylation of the activation loop was stimulated by R794G and F842L, and the autophosphorylation sites remained critical for GCN2 function in the presence of these mutations. Our results imply a two-step activation mechanism involving distinct conformational changes in the PK domain.

AN - 71641491; 11986222 AB - We studied the degree and the pattern of skewing of the variable region of beta-chain (VB) T-cell receptor (TCR) repertoire in aplastic anemia (AA) at initial presentation and after immunosuppression using a high-resolution analysis of the TCR VB complementarity-determining region 3 (CDR3). Age-matched healthy individuals and multitransfused patients with non-immune-mediated hematologic diseases were used as controls. In newly diagnosed AA, the average frequency of CDR3 size distribution deviation indicative of oligoclonal T-cell proliferation was increased (44% +/- 33% vs 9% +/- 9%; P =.0001); AA patients with human leukocyte antigen (HLA)-DR2 and those with expanded paroxysmal nocturnal hemoglobinuria clones showed more skewed VB repertoires. Nonrandom oligoclonal patterns were found for VB6, VB14-16, VB21, VB23, and VB24 subfamilies in more than 50%, and for VB15, VB21, and VB24 in more than 70% of AA patients with HLA-DR2. Patients received immunosuppression with antithymocyte globulin (ATG)/cyclosporine (CsA) or cyclophosphamide (CTX) with CsA in combination, and their VB repertoire was reanalyzed after treatment. Whereas no significant change in the degree of VB skewing in patients who had received ATG was seen, patients treated with CTX showed a much higher extent of oligoclonality within all VB families, consistent with a profound and long-lasting contraction of the T-cell repertoire. VB analysis did not correlate with the lymphocyte count prior to lymphocytotoxic therapy; however, after therapy the degree of VB skewing was highly reflective of the decrease in lymphocyte numbers, suggesting iatrogenic gaps in the VB repertoire rather than the emergence of clonal dominance.

Laboratories using an assay that detects only toxin A as their primary diagnostic test risk misdiagnosis of cases or outbreaks in the institutions they serve. Repeat testing can account for a significant portion of a laboratory's C. difficile testing workload. Published data are available to support laboratory rules for rejection of repeat stood specimens within 7 days of an initial specimen. There are also substantial published data to support laboratory rejection of formed stools sent to the laboratory for C. difficile testing.

Presented are important facts and mechanistic concepts on the capacity of selected transition metals, mainly Ni, but also Cu, Co, Cr, and briefly several others, to generate active oxygen species and other reactive intermediates under physiological conditions. These metals are known to be toxic and/or carcinogenic contaminants of the occupational and general environments. Their redox activity may underlay the mechanism of mediation of oxidative damage to cell constituents. The presentation is focused on selected issues relative to genetic and epigenetic toxicity and illustrated with examples of metal-mediated oxidative damage to the principal components of chromatin, i.e., DNA, histones, and protamines.

These gene neighborhoods are not typically present, in their entirety, in any single genome, but are held together by overlapping, partially conserved gene arrays. The procedure was applied to comparing the orders of orthologous genes, which were extracted from the database of Clusters of Orthologous Groups of proteins (COGs), in 31 prokaryotic genomes and resulted in the identification of 188 clusters of gene arrays, which included 1001 of 2890 COGs. These clusters were projected onto actual genomes to produce extended neighborhoods including additional genes, which are adjacent to the genes from the clusters and are transcribed in the same direction, which resulted in a total of 2387 COGs being included in the neighborhoods. Most of the neighborhoods consist predominantly of genes united by a coherent functional theme, but also include a minority of genes without an obvious functional connection to the main theme. We hypothesize that although some of the latter genes might have unsuspected roles, others are maintained within gene arrays because of the advantage of expression at a level that is typical of the given neighborhood. We designate this phenomenon `genomic hitchhiking'. The largest neighborhood includes 79 genes (COGs) and consists of overlapping, rearranged ribosomal protein superoperons; apparent genome hitchhiking is particularly typical of this neighborhood and other neighborhoods that consist of genes coding for translation machinery components. Several neighborhoods involve previously undetected connections between genes, allowing new functional predictions. Gene neighborhoods appear to evolve via complex rearrangement, with different combinations of genes from a neighborhood fixed in different lineages.

AN - 71686029; 12011455 AB - Molecular expression profiling of tumors initiated by transgenic overexpression of c-myc, c-neu, c-ha-ras, polyoma middle T antigen (PyMT) or simian virus 40 T/t antigen (T-ag) targeted to the mouse mammary gland have identified both common and oncogene-specific events associated with tumor formation and progression. The tumors shared great similarities in their gene-expression profiles as compared with the normal mammary gland with an induction of cell-cycle regulators, metabolic regulators, zinc finger proteins, and protein tyrosine phosphatases, along with the suppression of some protein tyrosine kinases. Selection and hierarchical clustering of the most variant genes, however, resulted in separating the mouse models into three groups with distinct oncogene-specific patterns of gene expression. Such an identification of targets specified by particular oncogenes may facilitate development of lesion-specific therapeutics and preclinical testing. Moreover, similarities in gene expression between human breast cancers and the mouse models have been identified, thus providing an important component for the validation of transgenic mammary cancer models.

A unique combination of environmental exposure and deficiency in these responses can lead to genomic instability; this "gene- environment interaction" paradigm is a theme for research on chronic disease etiology. In the present study, we used mouse embryonic fibroblasts with a gene deletion in the base excision repair (BER) enzymes DNA beta -polymerase ( beta -pol) and alkyladenine DNA glycosylase (AAG), along with exposure to methyl methanesulfonate (MMS) to study mutagenesis as a function of a particular gene-environment interaction. The beta -pol null cells, defective in BER, exhibit a modest increase in spontaneous mutagenesis compared with wild- type cells. MMS exposure increases mutant frequency in beta -pol null cells, but not in isogenic wild-type cells; UV light exposure or N-methyl-N'-nitro-N-nitrosoguanidine exposure increases mutant frequency similarly in both cell lines. The MMS-induced increase in mutant frequency in beta -pol null cells appears to be caused by DNA lesions that are AAG substrates, because overexpression of AAG in beta -pol null cells eliminates the effect. In contrast, beta -pol/AAG double null cells are slightly more mutable than the beta -pol null cells after MMS exposure. These results illustrate that BER plays a role in protecting mouse embryonic fibroblast cells against methylation-induced mutations and characterize the effect of a particular combination of BER gene defect and environmental exposure.

AN - 71722025; 12032773 AB - Hematopoiesis is the cumulative result of intricately regulated signal transduction cascades that are mediated by cytokines and their cognate receptors. Proper culmination of these diverse signaling pathways forms the basis for an orderly generation of different cell types and aberrations in these pathways is an underlying cause for diseases such as leukemias and other myeloproliferative and lymphoproliferative disorders. Over the past decade, downstream signal transduction events initiated upon cytokine/growth factor stimulation have been a major focus of basic and applied biomedical research. As a result, several key concepts have emerged allowing a better understanding of the complex signaling processes. A group of transcription factors, termed signal transducers and activators of transcription (STATs) appear to orchestrate the downstream events propagated by cytokine/growth factor interactions with their cognate receptors. Similarly, cytoplasmic Janus protein tyrosine kinases (JAKs) and Src family of kinases seem to play a critical role in diverse signal transduction pathways that govern cellular survival, proliferation, differentiation and apoptosis. Accumulating evidence suggests that STAT protein activation may be mediated by members of both JAK and Src family members following cytokine/growth factor stimulation. In addition, JAK kinases appear to be essential for the phosphorylation of the cytokine receptors which results in the creation of docking sites on the receptors for binding of SH2-containing proteins such as STATs, Src-kinases and other signaling intermediates. Cell and tissue-specificity of cytokine action appears to be determined by the nature of signal transduction pathways activated by cytokine/receptor interactions. The integration of these diverse signaling cues from active JAK kinases, members of the Src-family kinases and STAT proteins, leads to cell proliferation, cell survival and differentiation, the end-point of the cytokine/growth factor stimulus.

AN - 71655143; 11877441 AB - While cyclooxygenase (COX)-2 is a highly inducible gene, COX-1 is widely known as a noninducible gene and is constitutively expressed in a variety of cell lines and human tissues. Recently, several reports have indicated that COX-1 is also regulated at the transcriptional level by various stimuli. We present evidence that histone deacetylase (HDAC) inhibitors induce COX-1 transcription and translation in normal human astrocyte (NHA) cells and glioma cell lines. HDAC inhibitors increased acetylated histone H4 protein expression in NHA cells. The levels of COX-1 mRNA and protein were maximal at 24 and 48 h, respectively, after treatment with the specific HDAC inhibitor, trichostatin A (TSA). In addition, TSA-treated NHA cells produced prostaglandin E(2) as determined by enzyme-linked immunosorbent assay after incubation with 10 microm exogenous arachidonic acid, indicating that the induced COX-1 is functionally active. In addition to NHA cells, this up-regulation of COX-1 after treatment with HDAC inhibitors was observed in 5 different glioma cell lines. The nucleotide sequence of the inducible COX-1 cDNA was confirmed identical to human COX-1 that was previously reported. HDAC inhibitors stimulated COX-1 promoter activity as measured by luciferase reporter assays, suggesting that the induction of COX-1 is regulated at the transcriptional level. Furthermore, mutation analysis of the COX-1 promoter suggests that TSA-responsive element exists in the proximal Sp1-binding site at +25 to +31. In conclusion, COX-1 is an inducible gene in glial-derived cells including immortalized cells, and appears to be transcriptionally regulated by a unique mechanism associated with histone acetylation.

AN - 71490157; 11880179 AB - Non-clear cell rat kidney tumors, inducible by N-nitroso compounds but lacking mutations in the von Hippel--Lindau (VHL) coding sequence, were examined for other VHL alterations. Neither mutations nor DNA methylation was detected in a putative promoter region. By immunohistochemistry, however, VHL protein level was evidently reduced in six of the eight eosinophilic renal epithelial tumors and in all the ten nephroblastomas. Immunoblotting of normal kidney detected two VHL proteins of 20 and 22kDa in a 16-day-old fetal rat but only 20kDa protein in an adult rat. This is the first demonstration of VHL alteration at the protein level.

AN - 71489645; 11880187 AB - Previously, we demonstrated the significance of vascular endothelial growth factor (VEGF) in promoting the growth of tetracycline-regulated human VEGF165 retroviral vector transduced T47-D breast carcinoma cells, particularly at the early stages of tumor development (Cancer Res. 57 (1997) 3924). Here, we showed histologically that the VEGF overexpressing (VEGF (+)) T47-D cells formed a distinct tumor nodule at day 11, while control cells showed no evidence of replication. The VEGF (+) tumors contained large avascular cavities at days 11 and 21, which were replaced by basement membrane-lined channels at day 30. The number of proliferating tumor cells was not significantly different between the VEGF (+) and control tumors, but the number of apoptotic cells was significantly decreased in the VEGF (+) tumors. Increased nitric oxide synthase (NOS) activity was also observed in the VEGF (+) tumors. These findings indicate that VEGF contributes to tumor growth through inhibition of apoptosis and increased NOS activity, which may be critical during pre-vascular stages of tumor development.

AN - 72117754; 12269401 AB - Qingkailing (QKL) and Shuanghuanglian (SHHL) are two commonly used Chinese herbal preparations with reported antiinflammatory activity. The effects of these two preparations on the capacity of staphylococcal toxic shock syndrome toxin 1 (TSST-1) to stimulate the production of cytokines (IL-1beta, IL-6, TNF-alpha, IFN-gamma) and chemokines (MIP-1alpha, MIP-1beta and MCP-1) by peripheral blood mononuclear cell (PBMC) was tested. We also evaluated their effect on LPS-stimulated NF-kappaB transcriptional activity in a THP-1 cell line, and on human monocyte chemotactic response to chemoattractants. Non-cytotoxic concentrations of QKL (0.1 to approximately 2%) and SHHL (6 to approximately 120 microg) significantly inhibited production of cytokines and chemokines in a dose-dependent manner (P < 0.05). Both, QKL at 1:100 and SHHL at 60 microg/ml, markedly inhibited RANTES, MIP-1alpha, SDF-1alpha and fMLP induced human monocyte migration (P < 0.05 or 0.01). QKL (1%) did not inhibit monocyte chemotaxis induced by super-or sub-optimal concentrations of fMLP (10(-5), 10(-6) and 10(-10) M), but only inhibited chemotaxis induced by optimal concentrations of fMLP at 10(-7), 10(-8) and 10(-9) M. QKL (0.1% or 1%) and SHHL (6 or 60 microg/ml) markedly inhibited LPS-induced NF-kappaB activity in THP-1 cells. The results suggested that the pharmacological basis for the antiinflammatory effects of QKL and SHHL is the result of suppression of NF-kappaB regulated gene transcription, leading to suppressed production of proinflammatory cytokine and chemokine. Interference with leukocyte chemotaxis also contributes to the antiinflammatory and immunomodulating effects of these medicinals. Identification of the responsible components in these two herbal preparations may yield compounds suitable for structural modification into potent novel drugs.

AN - 71806440; 12054538 AB - We investigated the effect of thapsigargin, a well-known sarcoplasmic reticulum ATPase (SERCA) inhibitor, on the non-specific Ca2+ channel vanilloid receptor-1 (VR1) in CHO-VR1 cells. We found that thapsigargin inhibited the VR-1 mediated (45)Ca2+ uptake of CHO-VR1 cells (IC50=6.4+/-1.9 microM) and the [3H]RTX binding to VR1 (IC50=4.0+/-1.3 microM). Further analysis revealed that thapsigargin is a mixed-type inhibitor, suggesting both direct and indirect interactions between thapsigargin and the capsaicin binding site of VR1. Thapsigargin alone transiently elevated the [Ca2+]i in CHO-VR1 cells (EC50=44 nM). However, 45Ca2+ uptake was not detected after thapsigargin treatment, indicating that the emptying of the thapsigargin sensitive intracellular pools of Ca2+ was responsible for the elevated [Ca2+]i level rather than the activation of VR-1. We conclude that thapsigargin represents a new prototype of a VR1 inhibitor and that caution should be exercised in interpreting the effects of thapsigargin, especially when it is used in the micromolar range to inhibit SERCA activity.

The mouse epidermal JB6 cells constitute a model system that has significantly contributed to the understanding of these events. Clonal variants of JB6 cells are differentially responsive to transformation induced by tumor promoters such as phorbol esters (TPA), epidermal growth factor (EGF) and tumor necrosis factor alpha (TNF-a), as well as oxidative stress. TPA and EGF, acting through the MAP kinase pathway, activate AP-1 and subsequently NF-B proteins and downstream transcription processes that are involved in the transformation response in transformation-sensitive (P+) JB6 cells. The effect of TNF-a is primarily on the NF-B pathway. ROS and other free radicals can activate AP-1 and NF-B transcription coordinately. In JB6 cells, both ERK/Fra-1 and NF-B activity is essential for the transformation response. Inhibition of NF-B and AP-1 activity abrogates transformation in JB6 cells as well as in transgenic mice and human keratinocytes. A similar effect is seen with antioxidants, which inhibit NF-B and AP-1 activity as well as transformation in JB6 cells. The JB6 model is therefore valuable for monitoring early events in oxidative stress related signaling leading to carcinogenesis, and for identifying molecular targets for cancer chemoprevention.

AN - 85372753; pmid-12051440 AB - A recent report confirmed that stiffness of the stereocilia can be negative, as predicted by the Howard-Hudspeth model. According to this model, the mechanotransducer channel's gating not only reduces the stereociliary stiffness, but can alter its sign as well. The basic assumptions of this model do not include cooperativity in channel gating. Here we consider two possible explanations for the observed negative stiffness. If the stereocilia have a special structure so that microscopic displacement can be imposed on each channel by controlling the bending of the bundle, negative stiffness can occur without channel cooperativity. If such a microscopic condition cannot be imposed by a macroscopic manipulation, an additional physical process, such as cooperativity in channel gating, is required to explain negative stiffness.

AN - 85253370; pmid-12325392 AB - Functional magnetic resonance imaging was used to investigate preattentive and attentional processing of auditory stimuli in 18 right-handed normal volunteers. Responses to trains of 1000-Hz pure tones and infrequent (15%) deviant 1300-Hz tones were characterized while subjects ignored all tones; listened for deviants in the left ear; or listened for deviants in the right ear. Preattentive detection of deviants, associated with the mismatch negativity in electrophysiology, was associated with bilateral temporal lobe activation, with a rightward predominance. Processing of deviant stimuli while attending to either ear produced a more robust and widespread activation of these temporal regions, again with a rightward predominance. Thus, preattentive tone processing appears to be linked to asymmetric activation of a core set of temporal regions in which activity is significantly amplified by selective attention. Extratemporal regions activated by attending to targets in either ear included the anterior cingulate cortex, supramarginal gyrus, and dorsolateral prefrontal cortex.

AN - 85248411; pmid-12021826 AB - RATIONALE: Pre-clinical and clinical investigations have provided a great deal of evidence that the fear-potentiated startle paradigm represents a valid model for the objective assessment of emotional states of anxiety and fear. OBJECTIVE: The four studies presented in this report sought to further validate the "threat of shock" paradigm as a human analogue to fear-potentiated startle in rats, by examining the effect of benzodiazepine administration on both baseline and fear-potentiated startle. METHODS: Three studies, conducted at Utrecht University, evaluated the effects of oxazepam and of diazepam on baseline and fear-potentiated startle, whereas a fourth study, conducted at Yale University, evaluated the effect of diazepam on baseline, contextual and cue-specific fear-potentiated startle. The threat of shock paradigm consisted of verbal instruction about two visual cues (the threat cue predicted the possible administration of electric shock, the other predicted a safe period), followed by a series of presentations of these cues. During these conditions, acoustic startle stimuli were presented in order to elicit startle responses. The magnitude of the startle response was used to index the degree of fear or alarm experienced during the periods of threat and safety. The fourth study examined the effect of IV administration of diazepam in a similar threat of shock paradigm except that there were two additional context manipulations: electrode placement and darkness. RESULTS: None of the drug manipulations affected specific threat-cue potentiation of startle. However, reductions in baseline startle were observed. Further, startle potentiation by darkness was inhibited by diazepam. CONCLUSIONS: At least one type of fear-potentiated startle, i.e. potentiation by a cue-specific fear manipulation, is not susceptible to benzodiazepine treatment. In contrast, effects of manipulations more akin to anxiety (darkness, context) appear sensitive to benzodiazepines. Human experimental models differentiating between these cue specific and contextual responses are needed to shed more light on differences in the anatomy and pharmacology of anxiety disorders.

AN - 72800312; 12507173 AB - Inorganic arsenic exposure through drinking water causes cancer in adults; however, the carcinogenic potential in children remains unknown. A recent leukemia cluster in Churchill County, Nevada, where arsenic levels in water supplies are relatively high, has prompted concern. The authors investigated the incidence of childhood cancer between 1979 and 1999 in all 17 Nevada counties, grouped by low (i.e., < 10 microg/l), medium (10-25 microg/l), and high (35-90 microg/l) population-weighted arsenic levels in public drinking water supplies. The standardized incidence ratios (SIRs) for all childhood cancers combined were 1.00 (95% confidence interval [CI] = 0.94, 1.06), 0.72 (95% CI = 0.43, 1.12), and 1.25 (95% CI = 0.91, 1.69) for low-, medium-, and high-exposure counties, respectively. There was no relationship between arsenic levels in water and childhood leukemia (SIRs = 1.02, 0.61, and 0.86, respectively [95% CIIs = 0.90, 1.15; 0.12, 1.79; and 0.37, 1.70, respectively]). For all childhood cancers, excluding leukemias, the SIRs were 0.99 (95% CI = 0.92, 1.07), 0.82 (95% CI = 0.42, 1.22), and 1.37 (0.92, 1.83), respectively. The excess in 5- to 9-yr-old children and 10- to 14-yr-old children was in bone cancers, and the excess in 15- to 19-yr-old young adults was primarily in lymphomas. The findings in this study are reassuring in that leukemia risks were not increased at the concentrations of arsenic in water found in this study. Nonetheless, the results raise the possibility that there are increased risks for nonleukemic childhood cancers that require confirmation in other studies, particularly those in which higher exposures are addressed.

AN - 72698371; 12434305 AB - To examine the expression and promoter activation of the retinal pigment epithelium (RPE)-preferentially expressed Rpe65 gene in the commonly available RPE cell lines. Reverse transcription coupled to polymerase chain reaction (RT-PCR) was performed after total RNA extraction from different RPE (ARPE-19, monkey, hTERT-RP1 and D407) and non-RPE (COS-7, HeLa, HepG2 and HS27) cell lines. Promoter activity was assayed by transient transfection of luciferase reporter constructs containing nested deletions of the 5' flanking region of the mouse Rpe65 gene. The involvement of a putative TATA box in the basal promoter expression was studied by site-directed mutagenesis in D407 cells and binding of TATA box-related transcription factors to that region was demonstrated by Electrophoretic Mobility Shift Assays (EMSA). Expression of the human RPE65 cDNA was observed in all the RPE cell lines tested, and in COS-7 cells (monkey RPE65 cDNA). Transient transfections of the mouse Rpe65 promoter/luciferase transgene containing nested deletions of the Rpe65 5' flanking region showed that fragments containing bases -655 to +48 and -1240 to +48 generated specific promoter activity only in the D407 cell line. A promoter fragment from -49 to +48 directed basal promoter activity in all the cell lines tested. Part of this basal activity was due to a putative TATA box that specifically binds transcription factors contained in a D407 nuclear extract. Although transcription of the Rpe65 gene occurs in all the tested cell lines, we find that the D407 cell line is the only one capable of directing specific mouse Rpe65 promoter activity. This limits the study of the transcriptional regulation of the mouse Rpe65 gene in vitro to this particular cell line.

AN - 71989134; 12168820 AB - Adrenomedullin (AM) is a hypotensive polypeptide that has been shown to stimulate cyclic AMP and intracellular free Ca2+ agents that are known to induce expression of proto-oncogenes, in various cell types. Transforming growth factor-beta 1 (TGF-beta1) is a multifunctional polypeptide that regulates proliferation, differentiation and cell cycle progression in both normal and malignant epithelial cells. The diverse biological actions of AM and TGF-beta1 may be related to their capacities to initiate different genomic programs in target cells via the induction of expression of multiple genes including early response genes and proto-oncogenes. AM, TGF-beta1 and phorbol-12-myristate-13-acetate (PMA) exert both positive and negative effects on mitogenesis. The effects of AM, TGF-beta1 and PMA were examined in human non-small cell lung cancer (NSCLC) cells. AM caused an increase in its mRNA transcript that peaked by 6 hours and persisted to 24 hours. While expression of TGF-beta1 mRNA was not affected by AM in these cells, the mRNAs for TGF-beta1 and TGF-beta3 decreased by 3 hours. In contrast, TGF-beta1 had no effect on expression of AM mRNA. Interestingly, PMA caused an increase in AM and TGF-beta1 mRNAs in NSCLC cells. While both TGF-beta1 and PMA caused a transient increase in expression of the mRNAs for early response genes including c-fos, c-jun and egr-1 that peaked by 1 hour following treatment, the increase in expression of these mRNAs following treatment with AM peaked only after 3-6 hours. Western blotting analysis showed increases in the levels of c-jun protein following treatment with AM, TGF-beta1 and PMA. The increase in c-jun protein from treatment with AM occurred 10 hours after that from TGF-beta1 and PMA. Activator protein 1 (AP-1) DNA binding activity was also demonstrated to increase following treatment with AM, TGF-beta1 and PMA, with the increase in AP-1 DNA binding activity following AM treatment occurring 10 hours later than that from TGF-beta1 and PMA treatment. These data show that AM can regulate expression of its mRNA transcript in NSCLC cells.

AN - 71984577; 12162451 AB - Nitroxide free radicals have been shown to be potent antioxidants in a variety of experimental models using diverse means of insults. Among other insults, nitroxides have been shown effective in inhibiting cytotoxicity of quinone-based drugs such as streptonigrin and mitomycin C. These drugs and other chemotherapeutic agents have the potential to undergo bioreductive activation by the normal reducing enzymes within a cell. In the present work we studied the effect of the nitroxide Tempol on the cytotoxicity induced by EO9, a mitomycin C analogue, in HT29 cells under aerobic and hypoxic conditions. The study was aimed to better understand the mechanism of EO9 cytotoxicity and the molecular level of the nitroxide's mode of protection. The reactions of Tempol with activated EO9, and the reactive species formed during EO9 activation were studied in a cell-free solution, using spin-trapping, and electron paramagnetic resonance (EPR) spectrometry. Our results indicate that EO9 induced similar cytotoxicity in HT29 cells under aerobic and hypoxic conditions while Tempol provided similar and almost complete protection to both aerobic and hypoxic cells. The results indicate that EO9 cytotoxicity is due to both 1- and 2-electron reductive activation processes, with aerobic toxicity caused by back-oxidation of the hydroquinone to the semiquinone, EO9.-. Tempol serves both as a useful tool in the study of the mechanisms of quinone-mediated cytotoxicity and as a potent antioxidant against the damaging effects of redox cycling quinones and semiquinones by scavenging of EO9.- or detoxification of O2.- and H2O2.

AN - 71922529; 12128095 AB - Chromium(III) chloride is a common human exposure metal that is a preconceptional carcinogen in mice, although it enters cells poorly, and is non-toxic and non-carcinogenic in most biologic systems. An indirect effect on sperm is postulated, and this effect might be mediated through the testicular Sertoli cells that influence spermatogenesis. To test this possibility, we exposed mouse TM4 Sertoli-like cultured cells to 1mM CrCl(3) x 6H(2)O, a non-toxic dose, for 7 days and then extracted mRNA for microarray analysis. The chromium(III) chloride had modest effects on the expression of many genes, in the range of 1.5-2.3-fold. These effects provided an opportunity for development of statistical approaches for sifting microarray data in a situation where differences were small. Data were winnowed by screening for those ratios that fell outside the 99% confidence limits and/or represented a > or = 50% change in expression in the three comparison pairs. Fifty-two genes/clones were significant after the Bonferroni adjustment for multiple comparisons. The largest average increase was observed for the transcription factor Bach2, and this increase was confirmed by RT-PCR. The results show that Cr(III) has significant effects on gene expression in a Sertoli-like cell line. JF - Reproductive toxicology (Elmsford, N.Y.)

AN - 71892411; 12102580 AB - The detailed map of the human genome can potentially transform future cancer therapy by merging genomics with pharmacology, thereby identifying which patients will benefit from specific therapeutic agents. Single-nucleotide polymorphisms (SNPs) provide a valuable tool for this pharmacogenetic approach to cancer therapy. The discovery of SNPs as disease markers may facilitate identification of populations at increased risk for certain cancers. In addition, SNP genetic screening may facilitate administration of appropriate treatment modalities or reveal specific genetic profiles that have importance in drug efficacy and toxicity. In addition to SNP analysis, DNA and tissue microarray analyses have the potential to transform the future of cancer therapy. For example, DNA microarrays may improve tumor classification systems as well as provide a molecular level dissection of global gene expression changes that occur in carcinogenesis. Tissue microarrays would allow one to verify candidate genes, identified from DNA microarrays, against archival tumor specimens with known clinical outcome. In addition, both microarray technologies may be combined to rapidly validate gene targets. We will review and discuss these state-of-the-art technologies including data suggesting that the combined use of these high throughput technologies will facilitate our understanding of the genetic complexities inherent in cancer and will revolutionize cancer therapy.

AN - 71877415; 12099581 AB - Suramin, a polysulphonated napthylurea, has been extensively evaluated over the past 10 years as an anticancer agent, with the most interest in the treatment of prostate cancer. Early clinical results were promising with response rates of up to 70% being reported. However, a recent double-blind study showed only modest palliative effect in patients with androgen independent prostate cancer. In retrospect, it appears those initial reports failed to control for confounding variables such as antiandrogen withdrawal and hydrocortisone. Suramin causes numerous reversible toxicities (lethargy, rash, fatigue, anemia, hyperglycemia, hypocalcemia, coagulopathies, neutropenia, renal and hepatic complications). Neurotoxicity has been the most significant complication and appears to be related to the intensity of the dosing regimen. An optimal therapeutic dose has not been determined, but it is clear that adaptive controls add little benefit. Aside from moderate toxicities and the low therapeutic index in patients with prostate cancer, suramin's development has taught us some valuable lessons (i.e., anti-androgen withdrawal was noted during suramin's development, the use of PSA as an indicator of tumor burden was initiated during the evaluation of suramin). These lessons can be applied to all clinical trials in hormone refractory prostate cancer. Suramin has significantly enhanced the evolution of our knowledge in several areas of prostate cancer biology and treatment.

AN - 71857027; 12087420 AB - [structure: see text] o-Nitrotoluene is used to synthesize agricultural and rubber chemicals, azo and sulfur dyes, and dyes for cotton, wool, silk, leather, and paper. o-Nitrotoluene was nominated for study by NIOSH and the NTP based on its considerable human exposure as well as the absence of long-term studies of carcinogenicity in rodents. Male and female F344/N rats and B6C3F1 mice were exposed to o-nitrotoluene (greater than 99% pure) in feed for 2 years. Genetic toxicology studies were conducted in Salmonella typhimurium, cultured Chinese hamster ovary cells, rat and mouse bone marrow cells, and mouse peripheral blood erythrocytes. 2-YEAR STUDY IN RATS: In the core study, groups of 60 male and 60 female rats were fed diets containing 625, 1,250, or 2,000 ppm o-nitrotoluene (equivalent to average daily doses of approximately 25, 50, or 90 mg o-nitrotoluene/kg body weight to males and 30, 60, or 100 mg/kg to females) for 105 weeks. In a 3-month stop-exposure study, groups of 70 male rats were fed diets containing 2,000 or 5,000 ppm o-nitrotoluene (equivalent to average daily doses of approximately 125 or 315 mg/kg) for 13 weeks followed by undosed feed for the remainder of the study. A group of 70 male rats receiving undosed feed served as a control group for both male rat studies; 60 female rats receiving undosed feed were the control group for the female core study. Ten control males and 10 males from each stop-exposure group were sacrificed at 3 months. Survival, Body Weights, and Feed Consumption: All 2,000 ppm core study, all 5,000 ppm stop-exposure, and all but three core study 1,250 ppm male rats died before the end of the studies. Survival of 625 ppm core study and 2,000 ppm stop-exposure males and of 2,000 ppm females was significantly less than that of the controls. Mean body weights of all exposed groups of males except the 625 ppm group were generally less than those of the controls throughout the study. Mean body weights of 2,000 ppm females were less than those of the controls during year 2 of the study. Feed consumption by exposed groups of rats was similar to that by the controls. Biomarkers of Exposure: Three urinary metabolites were followed during the study as biomarkers of exposure. The ratios of o-nitrobenzoic acid to creatinine and of o-nitrobenzylmercapturic acid to creatinine determined at 2 weeks and at 3, 12, and 18 months were linearly related to exposure concentration in males and females. The ratio of o-aminobenzoic acid to creatinine was not related to exposure concentration. Pathology Findings: The incidences of malignant mesothelioma in male rats occurred with positive trends in both the core and stop-exposure studies and were significantly greater in exposed groups than in the controls. Incidences of subcutaneous skin neoplasms (fibroma, fibrosarcoma, and lipoma) were increased in exposed groups of males, while the incidences of fibroma or fibrosarcoma (combined) were increased in exposed females. In all exposed groups of males and females except 2,000 ppm core study males, the incidences of mammary gland fibroadenoma were significantly increased. The incidences of mammary gland hyperplasia were significantly increased in 625 and 1,250 ppm females. Increased incidences of mesothelioma, skin neoplasms, and mammary gland fibroadenoma in the stop-exposure males indicated that 3 months of dosing were sufficient to produce a carcinogenic effect. Liver weights of 5,000 ppm stop-exposure males were significantly greater than those of the controls at 3 months. The incidences of hepatocellular adenoma in 2,000 ppm core study males and females and of hepatocellular adenoma or carcinoma (combined) in 2,000 ppm core study and 5,000 ppm stop-exposure males were significantly increased. Cholangiocarcinoma occurred in three 5,000 ppm stop-exposure males, and a single hepatocholangiocarcinoma occurred in a 625 ppm male and in a 2,000 ppm core study male. Nonneoplastic lesions of the liver included eosinophilic, mixed cell, and clear cell foci in exposed groups of males and females and mixed cell infiltrate in exposed males and basophilic focus in exposed females. The incidences of alveolar/bronchiolar adenoma and alveolar/bronchiolar adenoma or carcinoma (combined) were significantly increased in 5,000 ppm stop-exposure males, as were alveolar/bronchiolar hyperplasia in most exposed groups of males and females. The incidences of hematopoietic cell proliferation of the spleen and of hyperplasia of the mandibular lymph node (females) and bone marrow were increased in exposed groups of males at 3 months and/or 2 years and in exposed groups of females at 2 years. The incidences of mononuclear cell leukemia were significantly decreased in all groups of males exposed to 1,250 ppm or greater and in all exposed groups of females; the incidence of testicular interstitial cell adenoma was significantly decreased in 5,000 ppm stop-exposure males. 2-YEAR STUDY IN MICE: Groups of 60 male and 60 female mice were fed diets containing 0, 1,250, 2,500, or 5,000 ppm o-nitrotoluene (equivalent to average daily doses of approximately 165, 360, or 700 mg/kg to males and 150, 320, or 710 mg/kg to females) for 105 weeks. Survival, Body Weights, and Feed Consumption: All 2,500 and 5,000 ppm males died before the end of the study. Survival of 1,250 ppm males and 5,000 ppm females was significantly less than that of the controls. Mean body weights of exposed males and 5,000 ppm females were generally less than those of the controls throughout the study, and those of 2,500 ppm females were less during the second year of the study. Feed consumption by 5,000 ppm males was less than that by the controls. Biomarkers of Exposure: Three urinary metabolites were followed during the study as biomarkers of exposure. The ratios of o-nitrobenzoic acid to creatinine determined at 2 weeks and at 3, 12, and 18 months were linearly related to exposure concentration in males and females. The concentrations of o-nitrobenzylmercapturic acid and o-aminobenzoic acid were below the limit of quantitation at most time points. Pathology Findings: The incidences of hemangiosarcoma in all exposed groups of males and in 5,000 ppm females were significantly greater than those in the controls. Large intestine (cecum) carcinomas were observed in all exposed groups except 5,000 ppm males. The incidences of hepatocellular neoplasms were significantly increased in 2,500 and 5,000 ppm females. Nonneoplastic liver lesions including eosinophilic and basophilic foci and minimal to mild necrosis were enhanced in exposed males and females. Also present were focal hepatocyte syncytial alteration in exposed males and hepatocyte necrosis and focal hepatocyte cytoplasmic vacuolization in 5,000 ppm females. Renal tubule pigmentation occurred more frequently in exposed groups of males and in 5,000 ppm females than in the controls. Olfactory epithelial degeneration occurred in every male and female mouse exposed to 2,500 or 5,000 ppm, and the severity of this lesion increased with increasing exposure concentration. o-Nitrotoluene was not mutagenic in any of several strains of S. typhimurium, with or without metabolic activation enzymes (S9). Sister chromatid exchanges were significantly increased in cultured Chinese hamster ovary cells following exposure to o-nitrotoluene in the presence of S9; an equivocal response was seen without S9. o-Nitrotoluene did not induce chromosomal aberrations in cultured Chinese hamster ovary cells, with or without S9. o-Nitrotoluene did not induce a significant increase in the frequency of micronuclei in bone marrow polychromatic erythrocytes of male rats or male mice when administered by intraperitoneal injection. Results of a peripheral blood micronucleus test were equivocal for male mice and negative for female mice administered o-nitrotoluene in feed for 13 weeks. Under the conditions of these studies, there was clear evidence of carcinogenic activity* of o-nitrotoluene in male rats based on increased incidences of malignant mesothelioma, subcutaneous skin neoplasms, mammary gland fibroadenoma, and liver neoplasms. The increased incidences of lung neoplasms in male rats were also considered to be exposure related. There was clear evidence of carcinogenic activity of o-nitrotoluene in female rats based on increased incidences of subcutaneous skin neoplasms and mammary gland fibroadenoma. The increased incidence of hepatocellular adenoma in female rats was also considered to be exposure related. There was clear evidence of carcinogenic activity of -o-nitrotoluene in male and female mice based on increased incidences of hemangiosarcoma, carcinoma of the large intestine (cecum), and hepatocellular neoplasms (females only). Exposure to o--nitrotoluene caused increased incidences of nonneoplastic lesions of the mammary gland (females only), liver, bone marrow, spleen, lung, and mandibular lymph node (females only) in male and female rats and of the liver, kidney, and nose in male and female mice. Decreased incidences of mononuclear cell leukemia occurred in exposed groups of rats; the incidence of testicular interstitial cell adenoma was decreased in exposed male rats.

AN - 71854944; 12084168 AB - Granulocyte donors are frequently given G-CSF with or without dexamethasone approximately 18 hours before apheresis to increase cell yields. The purpose of this study was to assess the kinetics of G-CSF plus dexamethasone neutrophil mobilization to determine whether the neutrophils can be mobilized and collected the same day. Sixteen subjects were given four separate mobilization regimens: IV G-CSF (5 microg/kg), subcutaneous G-CSF (5 microg/kg), IV G-CSF (5 microg/kg) plus oral dexamethasone (8 mg), and subcutaneous G-CSF (5 microg/kg) plus oral dexamethasone (8 mg). Blood cell counts were measured before and after G-CSF administration. Following all four mobilization regimens, neutrophil counts fell 0.5 hour after the mobilizing agents were given, rose above baseline levels at Hour 2, and increased further with each time interval to Hour 8. In the absence of dexamethasone at Hours 2 through 8, there was no difference in neutrophil counts by subcutaneous or IV G-CSF administration routes. The addition of dexamethasone enhanced mobilization of neutrophils from Hours 3 through 24. Through Hour 8, there was no difference in the degree of mobilization among the subcutaneous G-CSF plus dexamethasone and the IV G-CSF plus dexamethasone regimens. However, at Hour 24, neutrophil counts were sustained at higher levels with subcutaneous G-CSF plus dexamethasone than with IV G-CSF plus dexamethasone. Granulocyte mobilization response to subcutaneous G-CSF plus dexamethasone is sustained at peak levels for 8 to 24 hours after coadministration of the two drugs. There was no advantage to giving G-CSF intravenously.

AN - 71850465; 12084534 AB - The effects of thymosin alpha1 (Talpha1) on mammary carcinogenesis was investigated in Fisher rats. Mammary carcinomas were observed 3 months after N-nitrosomethylurea (NMU) injection (10mg, i.p.) into Fisher rats. Daily administration of Talpha1 (10 microg, s.c.) reduced mammary carcinoma incidence and prolonged survival time. Animals treated with exogenous Talpha1 had a significantly greater blood white cell density than control Fisher rats. These results suggest that Talpha1 prevents mammary carcinoma incidence as a result of stimulation of the immune system.

AN - 71847974; 12075704 AB - Metastases confined to the liver from tumors arising in the gastrointestinal tract or other sites represent a significant clinical problem. Although the majority of patients present with disease that is not amenable to resection based on the size, number, or anatomic distribution of tumors, for selected patients with limited extent of disease surgical resection can result in long-term survival. In patients with colorectal cancer, a number of adverse prognostic factors have been identified that are associated with shortened survival following hepatic resection. The role of adjuvant hepatic artery infusion and systemic chemotherapyfollowing resection in this patient population has been the topic of several prospective random assignment trials. For patients with unresectable metastases confined to liver, a number of regional therapies are in clinical development and share the advantages of intensifying therapy at the site of tumor while minimizing or eliminating unnecessary systemic exposure and toxicity. One such approach is vascular isolation and perfusion, also known as isolated hepatic perfusion or IHP, in which the liver is treated with high dose chemotherapy and/or biological agents under hyperthermic conditions. Although only a limited number of centers have reported substantial experience with this procedure, it appears to have significant efficacy even in patients with advanced tumor burden orthose with tumors refractory to other types of therapy. The status of IHP is presented. JF - Cancer journal (Sudbury, Mass.)

AN - 71847920; 12076985 AB - Immune stimulants, such as the bacterial endotoxin, lipopolysaccharide (LPS), the human immunodeficiency virus-1 coat protein gp120, or beta-amyloid peptides, lead to glial activation and production of various immune mediators, such as nitric oxide (NO) and proinflammatory cytokines in the brain. These mediators appear to contribute to neuronal cell death in neurodegenerative diseases. However, the signaling pathways, which mediate the neurotoxic effect by the endotoxin, are not understood. The purpose of this study was to determine the role of mitogen-activated protein kinase (MAPK) in LPS-induced neurodegeneration using mesencephalic dopaminergic neuron/glia cultures. We have found that the p38 MAPK is important in LPS-induced death of mesencephalic neurons in rat neuron-glia mixed cultures. Upon treatment with 10 ng/ml LPS, the number of dopaminergic neurons decreased by 80% within 48 h, preceded by a significant production of NO by glia. Neuroprotection by selective inhibition of p38 MAPK activity paralleled a decrease in LPS-induced inducible nitric oxide synthase (iNOS) expression. These events were significantly reduced by the selective p38 MAPK inhibitor, SB202190, but not by the inactive analogue SB202474. Inhibition of iNOS activity and NO production by treatment with GW274150 was also neuroprotective. Although the p38 MAPK inhibitor afforded significant neuroprotection from LPS toxicity in the neuron-glia mixed culture, it failed to protect dopaminergic neurons from 6-hydroxy-dopamine-induced toxicity, which acts directly on dopaminergic neurons by inducing hydroxyl radical formation from the mitochondria. The results suggest that p38 MAPK in glia plays a significant role in the LPS-induced death of mesencephalic neurons through induction of nitric oxide synthase and resulting NO production.

AN - 71844769; 12076986 AB - Glial activation is associated with inflammation-related neuron degeneration in the brain. A variety of protein kinases are assumed to contribute to the expression of inflammation-related products, such as nitric oxide (NO) and proinflammatory cytokines, however, the mechanisms of glial activation and glia-mediated neurotoxicity remain unclear. We found that the indolocarbazole, Gö6976, originally known as a selective protein kinase C (PKC) inhibitor, protects neurons from glia-mediated damage and suppresses lipopolysaccharide (LPS)-induced microglial production of inflammatory factors. The purpose of the study we report here was to determine the mechanism underlying the neuroprotective effect of Gö6976 in mesencephalic neuron/glia cultures. Gö6976 suppressed LPS-induced neurotoxicity in mesencephalic neuron/glia cultures and the protective effect of Gö6976 paralleled the suppression of p38 mitogen activated protein kinase (MAPK) activation and inhibition of NO production. Gö6976 did not directly inhibit the activity of p38 MAPK; rather, the inhibitor suppressed the phosphorylation of p38 MAPK, suggesting that the target of Gö6976 is a signaling event upstream of p38 MAPK. Although Gö6976 was originally known to be a selective PKC inhibitor, the neuroprotection was not mediated through its reputed effects on PKC activity. This paper demonstrates that the neuroprotective effect of Gö6976 against LPS-induced damage is mediated through the inhibition of proinflammatory factors, such as NO from microglia, by inhibiting the phosphorylation of p38 MAPK.

AN - 71835882; 12076984 AB - Increasing evidence has suggested that inflammation in the brain is closely associated with the pathogenesis of several degenerative neurologic disorders, including Parkinson's disease, Alzheimer's diseases, multiple sclerosis, amyotrophic lateral sclerosis, and AIDS dementia. The hallmark of brain inflammation is the activation of glial cells, especially that of microglia that produce a variety of proinflammatory and neurotoxic factors, including cytokines, fatty acid metabolites, free radicals--such as nitric oxide (NO) and superoxide. Excessive production of NO, as a consequence of nitric oxide synthase induction in activated glia, has been attributed to participate in neurodegeneration. Using primary mixed neuron-glia cultures and glia-enriched cultures prepared from embryonic rodent brain tissues, we have systemically studied the relationship between the production of NO and neurodegeneration in response to stimulation by the inflammagen lipopolysaccharide. This review summarizes our recent findings on the kinetics of NO generation, the relative contribution of microglia and astrocytes to NO accumulation, the relationship between NO production and neurodegeneration, and points of intervention along the pathways associated with NO generation to achieve neuroprotection. We also describe our results relating to the effect of several opioid-related agents on microglial activation and neuroprotection. Among these agents, the opioid receptor antagonist naloxone, especially its non-opioid enantiomer (+)-naloxone, promises to be of potential therapeutic value for the treatment of inflammation-related diseases.

After the visit, information on presenting complaint and physician's documentation of the patient's tobacco, alcohol and other drug use was abstracted from the medical record. The rates of alcohol and illicit drug use varied across assessment instruments; physician documentation, however, yielded the lowest prevalence estimates. Regular alcohol and drug users were more likely to present with chronic and acute medical problems than patients who were not regular users of these substances. The gynecology clinic offers an opportunity for early identification of women with substance problems, and alternative strategies are needed to encourage gynecologists to routinely screen for such problems at each medical visit.

AN - 71821455; 12069213 AB - We used Symptom Checklist 90-Revised (SCL90-R) to investigate psychiatric symptom severity in African-American drug-abusing individuals. Three hundred and seventeen African-American volunteers (52 control subjects; 265 drug users) were recruited, 19.2% of whom were HIV-positive. The impact of drug of choice or HIV status on mental distress was assessed. Symptomatic HIV-positive participants were excluded. The intake SCL90-R, Addiction Severity Index, and demographic data were subjected to regression analyses. Drug-abusing African Americans reported increased global distress, a finding that remained robust after we adjusted for HIV status, gender, age, and education. Drug of choice had no influence on the severity of global mental distress in our sample. Asymptomatic HIV-positive African Americans who abused drugs reported more distress than the HIV-negative drug users. Levels of global distress were similar in the HIV-negative and the HIV-positive controls. Subscales of the SCL90-R showed more symptom severity among drug-using, compared with nonusing, African Americans. Except for paranoia, anxiety, and obsessive-compulsive subscales, other symptom dimensions were significantly elevated in HIV-positive, compared with HIV-negative, drug abusers. When taken together, these findings suggest that drug abuse can exacerbate the severity of mental distress in HIV-positive patients. Treatment of these patients may be more successful if both sets of needs are addressed with matched interventions.

AN - 71799099; 12052147 AB - Pharmacogenomics is the application of genomic technologies to drug discovery and development, as well as for the elucidation of the mechanisms of drug action on cells and organisms. DNA microarrays measure genome-wide gene expression patterns and are an important tool for pharmacogenomic applications, such as the identification of molecular targets for drugs, toxicological studies and molecular diagnostics. Genome-wide investigations generate vast amounts of data and there is a need for computational methods to manage and analyze this information. Recently, several supervised methods, in which other information is utilized together with gene expression data, have been used to characterize genes and samples. The choice of analysis methods will influence the results and their interpretation, therefore it is important to be familiar with each method, its scope and limitations. Here, methods with special reference to applications for pharmacogenomics are reviewed.

AN - 71769262; 12041733 AB - Several major conceptual problems regarding specific in vivo functions of the TGF-beta family members remain the key focus of many researchers studying the biology of these secreted signaling molecules. More than 45 members of this family of growth factors have been identified and partially characterized for their molecular roles in numerous processes such as cell proliferation and differentiation, embryonic development, carcinogenesis, immune dysfunction, inflammation and wound healing. The high degree of similarity that exists at the structural level among the isoforms of these growth factors is accompanied by a significant overlap in function, as defined by many in vitro model systems and in vivo systems involving administration of exogenous ligand or of ligand-specific blocking antibodies. The ability to discern the critical functions of these molecules based on patterns of expression has also often been quite difficult. The evolution of more sophisticated functional genomics approaches has been recently instrumental in generating unique perspectives into the mechanisms governing the activity of the members of the TGF-beta family. The studies outlined in this review are significant in that they not only support working hypotheses regarding the activities of TGF-beta generated through extensive in vitro studies but also raise new questions regarding the role of each isoform in numerous processes. With the rapid advances in these approaches to probe activity in a more cell and time-dependent fashion, we will gain valuable insights for designing approaches for targeting the complex cellular pathways mediating their responses and will also help us develop novel therapies to treat disease processes.

AN - 71711257; 12015757 AB - Adrenocortical carcinoma (ACC) is rare, nearly always fatal, and to the authors' knowledge has few nonsurgical treatment options. Based on in vitro studies demonstrating the efficacy of mitotane as a P-glycoprotein (Pgp) antagonist, and expression of high levels of Pgp in ACC, the authors conducted a study of infusional doxorubicin, vincristine, and etoposide with oral mitotane +/- surgical resection in patients with metastatic ACC. Thirty-six patients with metastatic ACC received daily oral mitotane (mean, 4.6 g/day) and 96-hour infusional doxorubicin (10 mg/m(2)/day), etoposide (75 mg/m(2)/day), and vincristine (0.4 mg/m(2)/day). Four responding patients (11%) underwent surgery. Thirty-five patients were evaluable; all had metastatic disease. Eleven patients had not undergone resection of the primary tumor. Approximately 53% of patients had functional tumors. A total of 190 cycles were administered to 36 patients. Responses were observed in 8 patients (22%): 1 complete, 4 partial, and 3 minor responses. The mean duration of response was 12.4 months. Using a landmark method, the median survival of patients who did not respond to chemotherapy was 11.6 months from a point 4 months after the initiation of therapy, whereas that of 8 patients who demonstrated a response to chemotherapy was 34.3 months from that same landmark. High levels of Pgp expression were documented in nine of nine tumors. Mitotane levels > 10 microg/mL, previously shown to antagonize Pgp in vitro, were achieved in 25 of 36 patients (69%). However, rhodamine efflux from CD56-positive cells was not impaired, suggesting poor in vivo Pgp inhibition. The predominant Grade 3/4 toxicity (according to the Common Toxicity Criteria of the National Cancer Institute) was neutropenia in 66% of cycles; however, fever occurred in only 3% of cycles. Daily mitotane was associated with Grade 1/2 nausea, diarrhea, fatigue, and neuropsychiatric changes in 31 of 36 patients (86%). Using a combination regimen of daily mitotane with infusional doxorubicin, vincristine, and etoposide in patients with metastatic ACC, responses were observed in 22% of patients. The superiority of this combination over single-agent mitotane is uncertain. The side effects of mitotane made treatment difficult. More effective Pgp antagonists are needed.

AN - 71710365; 12015210 AB - Methamphetamine is a neurotoxic drug of abuse known to cause cell death both in vitro and in vivo. Nevertheless, the molecular and cellular mechanisms involved in this process remain to be clarified. Herein, we show that methamphetamine-induced apoptosis is associated with early (2 h) overexpression of bax, decreases of mitochondrial membrane potential and oxygen consumption as well as release of cytochrome c from mitochondria. In addition, activated caspase-9 was detected at 4 h post-METH exposure. Cell death was detectable by annexin V and propidium iodide staining after 8 h of methamphetamine exposure. At that time, the majority of the cells were stained by annexin V alone, with some cells being stained for both annexin V and propidium iodide. Moreover, cleavage of caspase-3, poly (ADP-ribose) polymerase and DNA fragmentation-related factor 45 was detected at 8 h post drug treatment. These results indicate that methamphetamine-induced apoptotic cell death results from early overexpression of bax, reduction of mitochondrial respiration and membrane potential and release of mitochondrial cytochrome c with subsequent activation of the caspase cascade.

There were statistically significant increases in safety belt use for 39 of 47 states and receipt of mammography in the past 2 years for women aged 40 years or older for 43 of 47 states. For persons aged 65 years or older, there were increases in receipt of influenza vaccination for 44 of 49 states and ever receiving pneumococcal vaccination for 48 of 49 states. State trends were mixed for binge alcohol use (increasing in 19 of 47 states and declining in 3), physical inactivity (increasing in 3 of 48 states and declining in 11), and cholesterol screening (increasing in 13 of 47 states and decreasing in 5). Obesity increased in all states and smoking increased in 14 of 47 states (declining only in Minnesota). Cervical cancer screening increased in 8 of 48 states and colorectal cancer screening increased in 13 of 49 states. New York experienced improvements for 8 of 11 measures, while 7 of 11 measures improved in Delaware, Kentucky, and Maryland; in contrast, Alaska experienced improvements for no measures and at least 4 of 11 measures worsened in Iowa, North Dakota, and South Dakota. Most states experienced increases in safety belt use, mammography, and adult vaccinations. Trends for smoking and binge alcohol use are disturbing, and obesity data support previous findings. Trend data are useful for targeting state preventive health efforts.

AN - 71695649; 12016155 AB - Heterozygous p53-deficient (p53(+/-)) mice, a potential model for human Li-Fraumeni Syndrome, have one functional allele of the p53 tumor suppressor gene. These mice are prone to spontaneous neoplasms, most commonly sarcoma and lymphoma; the median time to death of p53+/- mice is 18 months. We have shown previously that juvenile-onset calorie restriction (CR) to 60% of ad libitum (AL) intake delays tumor development in young p53-null (-/-) mice by a p53-independent and insulin-like growth factor 1 (IGF-1)-related mechanism. To determine whether CR is effective when started in adult p53-deficient mice, and to compare chronic CR with an intermittent fasting regimen, male p53+/- mice (7-10 months old, 31-32 mice/group) were randomly assigned to the following regimens: (i) AL (AIN-76A diet), (ii) CR to 60% of AL intake or (iii) 1 day/week fast. Food availability on non-fasting days was controlled to prevent compensatory over feeding. Relative to the AL group, CR significantly delayed (P = 0.001) the onset of tumors in adult mice, whereas the 1 day/week fast caused a moderate delay (P = 0.039). Substantial variation in longevity and maximum body weight within treatments was not correlated with variation in growth characteristics of individual mice. In a separate group of p53+/- mice treated for 4 weeks (n = five mice per treatment), plasma IGF-1 levels in CR versus AL mice were reduced by 20% (P < 0.01) and leptin levels were reduced by 71% (P < 0.01); fasted mice had intermediate levels of leptin and IGF-1. Our findings that CR or a 1 day/week fast suppressed carcinogenesis-even when started late in life in mice predestined to develop tumors due to decreased p53 gene dosage-support efforts to identify suitable interventions influencing energy balance in humans as a tool for cancer prevention.

AN - 71691197; 12016163 AB - 2-Amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP) is a food-borne mutagen and mammary gland carcinogen in female rats. A high-fat diet has been shown to increase the incidence of PhIP-induced mammary gland tumors. The current study used Big Blue rats harboring the lambda lacI mutational reporter transgene, to address whether the promotional effect of a high-fat diet is mediated via modulation in mammary gland mutagenesis. Big Blue rats were given 10 doses of PhIP (75 mg/kg, p.o.) and placed on defined low-fat (5% corn oil) or high-fat (23.5% corn oil) diet for 6 weeks prior to collecting mammary glands. The lacI mutant frequency (mean +/- standard error, n = 3 rats) was 231 +/- 15 (x10(-6)) and 193 +/- 12 (x10(-6)) in the low-and high-fat group, respectively. Values were increased 12-fold over control but were not significantly different between the two diets. In a parallel study, diet did not alter the mutant frequency induced by 7,12-dimethylbenz[a]anthracene (DMBA) (125 mg/kg, p.o.) in the mammary gland. The findings suggest that the promotion by the high-fat diet is not mediated via an increase in mutations. Consistent with the high potency of DMBA as a mammary carcinogen, the mutant frequency was 20-30% higher with DMBA than with PhIP. Sixty-nine and 56 PhIP-induced lacI mutants were sequenced from the low-and high-fat diet groups, respectively. While the percentage of various types of mutations was identical between the diet groups, some difference in the distribution of mutations along the lacI gene was observed. The mutation spectrum in the mammary gland from rats on both diets was consistent with the formation of PhIP-guanine adducts which were detected by a (32)P-post-labeling assay. Guanine base substitutions accounted for approximately 85% of all mutations irrespective of diet. Single base pair deletions at guanine occurred in 11-17% of mutants. G:C to T:A transversions were the predominant base substitution mutation accounting for 35-43% of all mutations. The majority of all guanine mutations (74%) occurred at guanine bases adjacent to another G:C pair. Five out of 125 (4%) mutations involved a guanine deletion in the 5'-GGGA-3' sequence, a PhIP signature mutation reported previously. Twelve out of 125 (10%) mutations involved the guanine base in the sequence 5'-CAG(Purine)-3' (Pu). The findings from these studies suggest that 5'-CAG(Pu)-3' is an additional characteristic target site for PhIP-guanine adduct-induced mutations in vivo in the mammary gland.

AN - 71684585; 12013352 AB - To characterize the pharmacokinetics of indinavir in the presence and absence of milk thistle and to determine the offset of any effect of milk thistle on indinavir disposition. Prospective open-label drug interaction study. Outpatient clinic. Ten healthy volunteers. Intervention. Blood samples were collected over 8 hours after the volunteers took four doses of indinavir 800 mg every 8 hours on an empty stomach for baseline pharmacokinetics. This dosing and sampling were repeated after the subjects took milk thistle 175 mg (confirmed to contain silymarin 153 mg, the active ingredient) 3 times/day for 3 weeks. After an 11-day washout, indinavir dosing and blood sampling were repeated to evaluate the offset of any potential interaction. Indinavir concentrations were measured by using a validated high-performance liquid chromatography method. The following pharmacokinetic parameters were determined: highest concentration (Cmax), hour-0 concentration, hour-8 concentration (C8), time to reach Cmax, and area under the plasma concentration-time curve over the 8-hour dosing interval (AUC8). Milk thistle did not alter significantly the overall exposure of indinavir, as evidenced by a 9% reduction in the indinavir AUC8 after 3 weeks of dosing with milk thistle, although the least squares mean trough level (C8) was significantly decreased by 25%. Milk thistle in commonly administered dosages should not interfere with indinavir therapy in patients infected with the human immunodeficiency virus.

AN - 71684285; 12009768 AB - Phenformin is a biguanide compound that can modulate glucose metabolism and promote weight loss and is therefore used to treat patients with type-2 diabetes. While phenformin may indirectly affect neurons by changing peripheral energy metabolism, the possibility that it directly affects neurons has not been examined. We now report that phenformin suppresses responses of hippocampal neurons to glutamate and decreases their vulnerability to excitotoxicity. Pretreatment of embryonic rat hippocampal cell cultures with phenformin protected neurons against glutamate-induced death, which was correlated with reduced calcium responses to glutamate. Immunoblot analyses showed that levels of the N-methyl-d-aspartate (NMDA) subunits NR1 and NR2A were significantly decreased in neurons exposed to phenformin, whereas levels of the AMPA receptor subunit GluR1 were unchanged. Whole-cell patch clamp analyses revealed that NMDA-induced currents were decreased, and AMPA-induced currents were unchanged in neurons pretreated with phenformin. Our data demonstrate that phenformin can protect neurons against excitotoxicity by differentially modulating levels of NMDA receptor subunits in a manner that decreases glutamate-induced calcium influx. These findings show that phenformin can modulate neuronal responses to glutamate, and suggest possible use of phenformin and related compounds in the prevention and/or treatment of neurodegenerative conditions.

AN - 71678056; 12003755 AB - Phthalates are ubiquitous in our modern environment because of their use in plastics and cosmetic products. Phthalate monoesters--primarily monoethylhexyl phthalate and monobutyl phthalate--are reproductive and developmental toxicants in animals. Accurate measures of phthalate exposure are needed to assess their human health effects. Phthalate monoesters have a biologic half-life of approximately 12 hr, and little is known about the temporal variability and daily reproducibility of urinary measures in humans. To explore these aspects, we measured seven phthalate monoesters and creatinine concentration in two consecutive first-morning urine specimens from 46 African-American women, ages 35-49 years, residing in the Washington, DC, area in 1996-1997. We measured phthalate monoesters using high-pressure liquid chromatography followed by tandem mass spectrometry on a triple quadrupole instrument using atmospheric pressure chemical ionization. We detected four phthalate monoesters in all subjects, with median levels of 31 ng/mL for monobenzyl phthalate (mBzP), 53 ng/mL for monobutyl phthalate (mBP), 211 ng/mL for monoethyl phthalate (mEP), and 7.3 ng/mL for monoethylhexyl phthalate (mEHP). These were similar to concentrations reported for other populations using spot urine specimens. Phthalate levels did not differ between the two sampling days. The Pearson correlation coefficient between the concentrations on the 2 days was 0.8 for mBP, 0.7 for mEHP, 0.6 for mEP, and 0.5 for mBzP. These results suggest that even with the short half-lives of phthalates, women's patterns of exposure may be sufficiently stable to assign an exposure level based on a single first morning void urine measurement.

Promising new studies of populations exposed in countries of the former Soviet Union are also discussed and include persons living near the Semipalatinsk Test Site in Kazakhstan, persons exposed as a result of the Chernobyl accident, and persons exposed as a result of operations of the Mayak Nuclear Plant in the Russian Federation. Very preliminary estimates of cancer risks from fallout doses received by the United States population are presented.

AN - 71670105; 12001058 AB - Thalidomide is used to treat human immunodeficiency virus (HIV)-associated conditions, including aphthous ulcers and wasting syndrome. The safety, tolerability, and pharmacokinetics of a formulation of thalidomide with improved bioavailability in HIV-infected persons was examined in a placebo-controlled, dose-escalating phase 1 study. Subjects with CD4 cell counts of 200-500 cells/mm(3) were enrolled and randomized 3:1 in groups of 12 to receive 50, 100, or 150 mg of thalidomide or matching placebo. Two subjects who received 150 mg of drug and 2 subjects assigned placebo experienced dose-limiting toxicity. Concentrations of thalidomide in the blood increased with escalating dose, but the time to maximum concentration and clearance did not differ across dose cohorts. Previous suggestions of autoinduction of drug metabolism were not confirmed by this study. At the doses studied, thalidomide was tolerated well and had linear pharmacokinetics.

AN - 71669753; 11978170 AB - To review preclinical and clinical information on flavopiridol, an inhibitor of cyclin-dependent kinases (CDKs), tested as an antitumor agent. Primary and review articles were identified by MEDLINE search (1990-June 2001). Abstracts from recent meetings were also used as source materials. Flavopiridol was reviewed with regard to its mechanisms, preclinical and clinical results, pharmacokinetics, and metabolism. Flavopiridol is an inhibitor of several CDKs and displays unique anticancer properties. In addition to direct CDK inhibition, flavopiridol also exhibited other features such as inducing apoptosis in many cancer cell lines, decreasing cyclin D1 concentration, and inhibiting angiogenesis. Preclinical xenograft models showed significant antitumor activity for flavopiridol. The regimen using 72-hour continuous infusion every 2 weeks has been most extensively applied in clinical trials, with a 1-hour infusion currently being explored to achieve higher peak concentrations. Several Phase I and II trials have been reported, with some evidence of antitumor activity noted. Further Phase I and II trials using flavopiridol as a single agent and in combination with standard chemotherapeutic regimens and various tumor types are ongoing. Flavopiridol is the first CDK inhibitor to enter clinical trials. Several Phase I and Phase II clinical trials with different regimens (72-h or 1-h infusion) have been completed. Initial clinical trials have been intriguing, but many questions remain: What is the best regimen (< or =72-h infusion)? Does optimal future development of this drug depend on the combination with other chemotherapy? What is the best combination of flavopiridol with other chemotherapy?

AN - 71650104; 11988840 AB - Activation of the insulin-like growth factor-1 receptor (IGF-1R) by IGF-1 is associated with the risk and progression of many types of cancer, although despite this it remains unclear how activated IGF-1R contributes to cancer progression. In this study, gene expression changes elicited by IGF-1 were profiled in breast epithelial cells. We noted that many genes are functionally linked to cancer progression and angiogenesis. To validate some of the changes observed, the RNA and/or protein was confirmed for c-fos, cytochrome P450 1A1, cytochrome P450 1B1, interleukin-1 beta, fas ligand, vascular endothelial growth factor, and urokinase plasminogen activator. Nuclear proteins were also temporally monitored to address how gene expression changes were regulated. We found that IGF-1 stimulated the nuclear translocation of phosphorylated AKT, hypoxic-inducible factor-1 alpha, and phosphorylated cAMP-responsive element-binding protein, which correlated with temporal changes in gene expression. Next, the promoter regions of IGF-1-regulated genes were searched in silico. The promoters of genes that clustered together had similar regulatory regions. In summary, IGF-1 inscribes a gene expression profile relevant to cancer progression, and this study provides insight into the mechanism(s) whereby some of these changes occur.

Last updated - 2017-01-18 ER - TY - JOUR T1 - Alcohol, breastfeeding, and development at 18 months. AN - 71645934; 11986478 AB - We aimed to replicate a previous study of 1-year-olds that reported a deficit in motor development associated with moderate alcohol use during lactation, using a different but comparable population. The mental development of 915 18-month-old toddlers from a random sample of a longitudinal population-based study in the United Kingdom was measured using the Griffiths Developmental Scales. Frequent self-administered questionnaires during and after pregnancy provided maternal data. The dose of alcohol available to the lactating infant was obtained by multiplying the alcohol intake of the mother by the proportion of breast milk in the infant's diet. We compared this dose with the Griffiths Scales of Mental Development, taking into account potentially confounding variables. Three of the Griffiths scales increased slightly but significantly with increasing infant alcohol exposure; there was no association in the remaining 2 or average of the scales. We were unable to replicate the earlier deficit in motor skills associated with lactation alcohol use. One reason may be that the dose of alcohol reaching the lactating infant is small, and tests of infants and toddlers have limited ability to pick up small effects. Studies of older children may resolve the question of the safety of drinking while nursing.

AN - 71640167; 11980865 AB - Monocyte chemoattractant protein (MCP)-1 (CCL-2) is a chemokine with chemoattractant properties for monocytes, memory T cells, natural killer cells, mast cells, and basophils. To delineate the role played by MCP-1 in acute anterior uveitis, a common ocular inflammation, MCP-1(-/-) mice and wild-type matched control mice were analyzed for the development of endotoxin-induced uveitis (EIU) in response to subcutaneous injection of a sublethal dose of lipopolysaccharide (LPS). EIU was induced in MCP-1(-/-) and wild-type control mice by a single subcutaneous injection of Salmonella typhimurium LPS endotoxin at day 0. Alternatively, MCP-1(-/-) mice were injected subcutaneously with LPS plus recombinant MCP-1 at day 0 and with recombinant MCP-1 6 hours later. Mice were killed at day 1 or 3 after injection. Serum levels of IL-1alpha, IL-1beta, IL-6, IFN-gamma, TNF-alpha, granulocyte-macrophage colony-stimulating factor (GM-CSF), macrophage inflammatory protein (MIP)-1alpha, MIP-2, regulated on activation normal T-cell expressed and secreted (RANTES), and MCP-1 were determined by ELISA. Eyes were collected and analyzed histologically and by RT-PCR for MCP-1, IFN-gamma, IL-6, TNF-alpha, beta-actin, MCP-5, RANTES, KC, inflammatory protein (IP)-10, and toll-like receptor (TLR)-4. EIU was strongly reduced in MCP-1(-/-) mice compared with wild-type control mice. The number of ocular inflammatory cells was significantly reduced. Moreover, intraocular IFN-gamma transcription was increased. EIU was induced in MCP-1(-/-) mice by co-administration of recombinant rat MCP-1 and LPS. Data indicate that MCP-1 plays a crucial role in the induction of EIU. MCP-1 may be a new therapeutic strategy for acute anterior uveitis.

AN - 71639683; 11981142 AB - There are few repeated dose-controlled trials of N-methyl-d-aspartate glutamate receptor antagonists in patients with neuropathic pain. The authors sought to evaluate two low-affinity N-methyl-d-aspartate antagonists using a novel two-stage design. The authors studied patients with painful diabetic neuropathy (DN) and postherpetic neuralgia (PHN) in two crossover trials: (1) efficacy trial (dextromethorphan vs. memantine vs. active placebo [lorazepam]) and (2) dose-response trial of the preferred active drug in responders from the first study (0% vs. 25% vs. 50% vs. 100% of each patient's maximally tolerated dose). Pain intensity was measured on a 20-point scale. Nineteen of 23 DN patients and 17 of 21 PHN patients completed the efficacy trial. Median doses for DN and PHN were 400 and 400 mg/day dextromethorphan, 55 and 35 mg/day memantine, and 1.8 and 1.2 mg/day lorazepam. In the efficacy trial, among patients with DN, dextromethorphan reduced pain intensity by a mean of 33% from baseline, memantine reduced pain intensity by a mean of 17%, and lorazepam reduced pain intensity by a mean of 16%; the proportions of subjects achieving greater than moderate pain relief were 68% with dextromethorphan, 47% with memantine, and 37% with lorazepam. Mean reductions in pain intensity in patients with PHN were 6% with dextromethorphan, 2% with memantine, and 0% with lorazepam. No comparison with placebo reached statistical significance in the efficacy trial. In the 10 DN subjects who responded to dextromethorphan, there was a significant dose-response effect on pain intensity (P = 0.035), with the highest dose significantly better than that of lorazepam (P = 0.03). Dextromethorphan is effective in a dose-related fashion in selected patients with DN. This was not true of PHN, suggesting a difference in pain mechanisms. Selective approaches to pain-relevant N-methyl-d-aspartate receptors are warranted.

AN - 71637001; 11984525 AB - Nonsteroidal anti-inflammatory drugs (NSAIDs) induce NSAID-activated gene 1 (NAG-1), which has proapoptotic and antitumorigenic activities. However, NAG-1 expression and its relationship with apoptosis in human and mouse intestinal tract have not been determined. NAG-1 expression in human and mouse tissue was determined by immunohistochemistry, and apoptosis was estimated by in situ apoptosis detection. Apoptosis in NAG-1 overexpressing HCT-116 cells was examined with flow cytometry after cell sorting by green fluorescence protein. NAG-1 regulation in mouse cells was examined by Northern blot analysis, comparing sulindac-treated and nontreated mice. Apoptosis was higher in NAG-1 overexpressing cells compared with controls. Human NAG-1 protein was localized to the colonic surface epithelium where cells undergo apoptosis, and higher expression was observed in the normal surface epithelium than in most of the tumors. This localization and lower expression in tumors was similar to that in the Min mouse, in which NSAIDs were also shown to regulate the expression of NAG-1 in mouse cells. Sulindac treatment of mice increased the NAG-1 expression in the colon and liver. Based on these results, we propose that NAG-1 acts as a mediator of apoptosis in intestinal cells and may contribute to cancer chemoprevention by NSAIDs.

AN - 71635558; 11981763 AB - Global gene expression profiles in cancer have impacted both classification of tumors and definition of molecular pathways in neoplasia. To explore the possibility of employing human tumor cell lines to obtain information on the functional genomics of the early stages of tumorigenesis, we have characterized variation in gene-expression patterns in a cytogenetically well-defined series of cell lines derived from human hepatocellular carcinoma (HCC). Microarrays containing 6,720 sequence-verified human cDNAs were used in this study. Nineteen well-characterized HCC cell lines were analyzed, and a nontumorigenic liver-derived epithelial cell line (Chang) was used as a reference. Each sample was examined at least twice by switching fluorescent dyes, Cy-5 and Cy-3, and average values of 2 experiments on each sample were used for further analysis. Analysis of the clustered data revealed 2 distinctive subtypes of gene-expression patterns among the 19 cell lines, suggesting a degree of heterogeneity among the gene-expression profiles of cell lines. Remarkably, expression of alpha-fetoprotein (AFP) was highly correlated with the molecular subtypes of HCC. Although the 3 most distinctive gene-expression modules represented the signatures of 2 different subgroups of HCC, most of the cell lines shared many coexpressed genes. However, sets of coexpressed genes that are specific for the subtypes of HCC were identified. Furthermore, our results indicate that the comparison between gene-expression patterns and structural alterations in chromosomes is potentially useful in identifying genes critical in early stages of tumorigenesis. In conclusion, these results not only identified unrecognized subtypes of HCC, but also provided potential molecular markers for each subtype that can be useful for diagnostic and/or therapeutic purposes.

AN - 71634338; 11978584 AB - This study reports on over 40 years of mortality follow-up of 40,581 Navy veterans of the Korean War with potential exposure to high-intensity radar. The cohort death rates were compared with mortality rates for White US men using standardized mortality ratios, and the death rates for men in occupations considered a priori to have high radar exposure were compared with the rates for men in low-exposure occupations using Poisson regression. Deaths from all diseases and all cancers were significantly below expectation overall and for the 20,021 sailors with high radar exposure potential. There was no evidence of increased brain cancer in the entire cohort (standardized mortality ratio (SMR) = 0.9, 95% confidence interval (CI): 0.7, 1.1) or in high-exposure occupations (SMR = 0.7, 95% CI: 0.5, 1.0). Testicular cancer deaths also occurred less frequently than expected in the entire cohort and high-exposure occupations. Death rates for several smoking-related diseases were significantly lower in the high-exposure occupations. Nonlymphocytic leukemia was significantly elevated among men in high-exposure occupations but in only one of the three high-exposure occupations, namely, electronics technicians in aviation squadrons (SMR = 2.2, 95% CI: 1.3, 3.7). Radar exposure had little effect on mortality in this cohort of US Navy veterans.

AN - 71632911; 11979356 AB - BK virus (BKV) was recovered by polymerase chain reaction (PCR) from brain, kidney, lung, urine, and cerebrospinal fluid (CSF) of a fatal case of BKV tubulointerstitial nephritis with dissemination to lung and brain. Viral regulatory regions in PCR-amplified urine and the lung samples were identical to the archetypal structure, WWT. In the brain and CSF, a rearranged sequence predominated, however. A 94-bp deletion preceded a 71-bp tandem duplication because the same 94-bp segment was deleted from both copies. PCR-amplified regulatory region products were cloned and sequenced to define further the extent of the rearranged structures. Two kidney clones were archetypal, whereas two others were rearranged differently from the brain and from each other. In contrast to the brain clones, the kidney rearrangements seemed to involve deletion after duplication. Three of four brain clones sequenced were identical to the rearrangement found to dominate in the PCR product. A fourth clone showed two short deletions without any duplication. The four CSF clones all showed rearrangements identical to that which was amplified by PCR from CSF and brain. This represents the first molecular analysis of a BKV strain obtained from a central nervous system infection, and it reveals regulatory region rearrangements reminiscent of those described in JC virus from brains with progressive multifocal leukoencephalopathy. We suggest that the presence in the CSF of BKV with a dominant rearranged regulatory region may be useful in the diagnosis of BKV meningoencephalitis secondary to BKV nephritis.

AN - 71632801; 11980658 AB - Human mitotic arrest deficiency protein 1, hsMAD1, is a component of the mitotic spindle assembly checkpoint (MSC) that monitors fidelity of chromosomal segregation and guards against emergence of cellular aneuploidy. Because aneuploidy is a pervasive characteristic of human cancers, understanding how MSC genes are regulated is important. Here, we have analyzed human genomic sequences upstream of the 5' most hsMAD1 coding exon and have identified a 1.5-kb fragment with promoter activity. The hsMad1 promoter, consistent with characteristics of housekeeping genes, is highly GC rich and is devoid of a TATA-box. Mutational analyses revealed a core region spanning -73 to -31 as being essential for hsMad1 transcription. Surprisingly, although MSC function, prototypically induced by microtubule inhibitors, is active selectively during mitosis, we found the hsMad1 promoter to be expressed predominantly in G1 and to respond not to microtubule inhibitor but to mitogenic stimulus. In primary, as well as transformed cells, intracellular levels of hsMAD1 correlated with the proliferative status of cells. The hsMad1 promoter was also activated preferentially by a gain-of-function p53 mutant. Taken together, our results suggest that hsMAD1 might link p53 function to the generation of cellular aneuuploidy and that heightened activation of hsMad1 by gain-of-function p53 mutants could contribute to the worse prognosis of certain cancers.

AN - 71630873; 11978855 AB - Stress affects seizure susceptibility in animals and humans, but the underlying mechanisms are obscure. Here, we provide evidence that GABA(A) receptor-modulating neurosteroids derived from deoxycorticosterone (DOC) play a role in stress-related changes in seizure control. DOC, an adrenal steroid whose synthesis is enhanced during stress, undergoes sequential metabolic reduction by 5alpha-reductase and 3alpha-hydroxysteroid oxidoreductase to form 5alpha-dihydrodeoxycorticosterone (DHDOC) and allotetrahydrodeoxycorticosterone (THDOC), a GABA(A) receptor-modulating neurosteroid with anticonvulsant properties. Acute swim stress in rats significantly elevated plasma THDOC concentrations and raised the pentylenetetrazol (PTZ) seizure threshold. Small systemic doses of DOC produced comparable increases in THDOC and PTZ seizure threshold. Pretreatment with finasteride, a 5alpha-reductase inhibitor that blocks the conversion of DOC to DHDOC, reversed the antiseizure effects of stress. DOC also elevated plasma THDOC levels and protected mice against PTZ, methyl-6,7-dimethoxy-4-ethyl-beta-carboline-3-carboxylate, picrotoxin, and amygdala-kindled seizures in mice (ED50 values, 84-97 mg/kg). Finasteride reversed the antiseizure activity of DOC (ED50, 7.2 mg/kg); partial antagonism was also obtained with indomethacin (100 mg/kg), an inhibitor of 3alpha-hydroxysteroid oxidoreductase. Finasteride had no effect on seizure protection by DHDOC and THDOC, whereas indomethacin partially reversed DHDOC but not THDOC. DHDOC, like THDOC, potentiated GABA-activated Cl- currents in cultured hippocampal neurons ( or =1 microm), compatible with a role for DHDOC in the antiseizure activity of DOC. DOC is a mediator of the physiological effects of acute stress that could contribute to stress-induced changes in seizure susceptibility through its conversion to neurosteroids with modulatory actions on GABA(A) receptors including THDOC and possibly also DHDOC.

AN - 71630107; 11923218 AB - It is often assumed that bone mineral accretion should be optimized throughout childhood to maximize peak bone mass. In contrast, we hypothesized that bone mineral acquisition early in life would have little or no effect on adult bone mass because many areas of the juvenile skeleton are replaced in toto through skeletal growth. To test this hypothesis, we induced osteoporosis by administering dexamethasone to 5-week-old rabbits for 5 weeks and then allowed them to recover for 16 weeks. Tibial bone mineral density (ash weight/volume) was decreased in the dexamethasone-treated animals at the end of treatment but recovered completely. Bone structure in the femur was assessed by histomorphometry. Trabecular and cortical bone in the distal metaphysis was made osteoporotic by dexamethasone, but was then replaced through endochondral bone formation and recovered. Periosteal bone formation rate in the diaphysis was decreased during dexamethasone treatment but afterwards rebounded above controls and normalized cortical width. Our data suggest that bone mineral acquisition early in life has little effect on adult bone density because the juvenile bone is largely replaced through growth. If this concept generalizes, then interventions to maximize peak bone mass should be directed at adolescents rather than young children.

AN - 71627572; 11971025 AB - Overexpression of the inducible cyclooxygenase (COX-2) and inducible NO synthase (iNOS) in activated brain macrophages (microglia) and astrocytes appears central to many neuroinflammatory conditions. 15-Deoxy-Delta(12,14)-PGJ(2) (15d-PGJ(2)) is a ligand for the peroxisome proliferator-activated receptor (PPAR)gamma. It has been proposed as an inhibitor of microglial activation, based on the study of iNOS down-regulation in rodent microglia. Because iNOS induction after cytokine activation remains controversial in human microglia, we examined the effect of 15d-PGJ(2) and other PPAR agonists on human microglia and astrocytes, using COX-2 induction as an index of activation. We found that PPAR alpha ligands (clofibrate and WY14643) enhanced IL-1 beta-induced COX-2 expression in human astrocytes and microglia, while inhibiting IL-1 beta plus IFN-gamma induction of iNOS in astrocytes. This is the first description of an inhibition of iNOS uncoupled from that of COX-2. 15d-PGJ(2) suppressed COX-2 induction in human astrocytes. It prevented NF-kappa B binding to the COX-2 promoter through a new pathway that is the repression of NF-kappa Bp50 induction by IL-1 beta. In contrast, 15d-PGJ(2) increased c-Jun and c-Fos DNA-binding activity in astrocytes, which may result in the activation of other inflammatory pathways. In human microglia, no effect of 15d-PGJ(2) on COX-2 and NF-kappa Bp65/p50 induction was observed. However, the entry of 15d-PGJ(2) occurred in microglia because STAT-1 and c-Jun expression was modulated. Our data suggest the existence of novel pathways mediated by 15d-PGJ(2) in human astrocytes. They also demonstrate that, unlike astrocytes and peripheral macrophages or rodent brain macrophages, human microglia are not subject to the anti-inflammatory effect of 15d-PGJ(2) in terms of COX-2 inhibition.

AN - 71623410; 11976296 AB - Although very little replication past a T-T cis-syn cyclobutane dimer normally takes place in Escherichia coli in the absence of DNA polymerase V (Pol V), we previously observed as much as half of the wild-type bypass frequency in Pol V-deficient (DeltaumuDC) strains if the 3' to 5' exonuclease proofreading activity of the Pol III epsilon subunit was also disabled by mutD5. This observation might be explained in at least two ways. In the absence of Pol V, wild-type Pol III might bind preferentially to the blocked primer terminus but be incapable of bypass, whereas the proofreading-deficient enzyme might dissociate more readily, providing access to bypass polymerases. Alternatively, even though wild-type Pol III is generally regarded as being incapable of lesion bypass, proofreading-impaired Pol III might itself perform this function. We have investigated this issue by examining dimer bypass frequencies in DeltaumuDC mutD5 strains that were also deficient for Pol I, Pol II, and Pol IV, both singly and in all combinations. Dimer bypass frequencies were not decreased in any of these strains and indeed in some were increased to levels approaching those found in strains containing Pol V. Efficient dimer bypass was, however, entirely dependent on the proofreading deficiency imparted by mutD5, indicating the surprising conclusion that bypass was probably performed by the mutD5 Pol III enzyme itself. This mutant polymerase does not replicate past the much more distorted T-T (6-4) photoadduct, however, suggesting that it may only replicate past lesions, like the T-T dimer, that form base pairs normally.

AN - 71613919; 11964933 AB - Previous interview-based studies have suggested that exposure to neurotoxicants including metals might be related to ALS. We evaluated the relation of lead exposure to ALS, using both biological measures and interviews, in a case-control study conducted in New England from 1993 to 1996. Cases (N = 109) were recruited at two hospitals in Boston, MA. Population controls (N = 256) identified by random-digit dialing were frequency-matched to cases by age, sex, and region of residence within New England. Risk of ALS was associated with self-reported occupational exposure to lead (odds ratio [OR] = 1.9; 95% confidence interval [CI] = 1.1-3.3), with a dose response for lifetime days of lead exposure. Blood and bone lead levels were measured in most cases (N = 107) and in a subset of controls (N = 41). Risk of ALS was associated with elevations in both blood and bone lead levels.

Two distinct families of NK receptors have been identified: the C-type lectin-like family (Ly49, NKG2D and CD94/NKG2) and the immunoglobulin-like family (KIRs and LIRs). Here, we describe the crystal structure of the C-type lectin-like NK receptor (Ly49A), bound to its MHC-I ligand (H-2D(d)). We also discuss results from recent mutagenesis studies of the Ly49A/H-2D(d) interaction in the context of the complex structure.

AN - 71599936; 11959680 AB - Aging alters many aspects of circadian rhythmicity, including responsivity to phase-shifting stimuli and the amplitude of the rhythm of melatonin secretion. As melatonin is both an output from and an input to the circadian clock, we hypothesized that the decreased melatonin levels exhibited by old hamsters may adversely impact the circadian system as a whole. We enhanced the diurnal rhythm of melatonin by feeding melatonin to young and old hamsters. Animals of both age groups on the melatonin diet showed larger phase shifts than control-fed animals in response to an injection with the benzodiazepine triazolam at a circadian time known to induce phase advances in the activity rhythm of young animals. Thus melatonin treatment can increase the sensitivity of the circadian timing system of young animals to a nonphotic stimulus, and the ability to increase this sensitivity persists into old age, indicating exogenous melatonin might be useful in reversing at least some age-related changes in circadian clock function.

AN - 71589356; 11940668 AB - The extracellular zona pellucida surrounding mammalian eggs is formed by interactions of the ZP1, ZP2, and ZP3 glycoproteins. Female mice lacking ZP2 or ZP3 do not form a stable zona matrix and are sterile. The three zona proteins are synthesized in growing oocytes and secreted prior to incorporation into the zona pellucida. A well-conserved furin site upstream of a transmembrane domain near the carboxyl terminus of each has been implicated in the release of the zona ectodomains from oocytes. However, mutation of the furin site (RNRR --> ANAA) does not affect the intracellular trafficking or secretion of an enhanced green fluorescent protein (EGFP)-ZP3 fusion protein in heterologous somatic cells. After transient expression in growing oocytes, normal EGFP-ZP3 and mutant EGFP-ZP3 associate with the inner aspect of the zona pellucida, which is distinct from the plasma membrane. These in vitro results are confirmed in transgenic mice expressing EGFP-ZP3 with or without the mutant furin site. In each case, EGFP-ZP3 is incorporated throughout the width of the zona pellucida and the transgenic mice are fertile. These results indicate that the zona matrix accrues from the inside out and, unexpectedly, suggest that cleavage at the furin site is not required for formation of the extracellular zona pellucida surrounding mouse eggs.

AN - 71577949; 11934688 AB - The anti-inflammatory cytokines alpha-melanocyte-stimulating hormone (MSH) and interleukin (IL)-10 inhibit acute renal failure (ARF) after ischemia or cisplatin administration; however, these agents have not been tested in a pure nephrotoxic model of ARF. Therefore, we examined the effects of alpha-MSH and IL-10 in HgCl(2)-induced ARF. Mice were injected subcutaneously with HgCl(2) and then given vehicle, alpha-MSH, or IL-10 by intravenous injection. Animals were killed to study serum creatinine, histology, and myeloperoxidase activity. Treatment with either alpha-MSH or IL-10 did not alter the increase in serum creatinine, tubular damage, or leukocyte accumulation at 48 h after HgCl(2) injection. Because alpha-MSH and IL-10 are active in other injury models that involve leukocytes, we studied the time course of tubular damage and leukocyte accumulation to investigate whether leukocytes caused the tubular damage or accumulated in response to the tubular damage. Tubular damage was present in the outer stripe 12 h after HgCl(2) injection. In contrast, the number of leukocytes and renal myleoperoxidase activity were normal at 12 h but were significantly increased at 24 and 48 h after injection. We conclude that neither alpha-MSH nor IL-10 altered the course of HgCl(2)-induced renal injury. Because the tubular damage preceded leukocyte infiltration, the delayed leukocyte accumulation may play a role in the removal of necrotic tissue and/or tissue repair in HgCl(2)-induced ARF.

AN - 71570162; 11934698 AB - We used confocal microscopy and quantitative image analysis to follow the movement of the fluorescent organic anion fluorescein (FL) from bath to cell and cell to blood vessel in intact rat lateral choroid plexus. FL accumulation in epithelial cells and underlying vessels was rapid, concentrative, and reduced by other organic anions. At steady state, cell fluorescence exceeded bath fluorescence by a factor of 3-5, and vessel fluorescence exceeded cell fluorescence by a factor of approximately 2. In cells, FL distributed between diffuse and punctate compartments. Cell and vessel accumulation of FL decreased when metabolism was inhibited by KCN, when bath Na(+) was reduced from 130 to 26 mM, and when the Na(+) gradient was collapsed with ouabain. Cell and vessel accumulation increased by >50% when 1-10 microM glutarate was added to the bath. Finally, transport of FL and carboxyfluorescein (generated intracellularly from carboxyfluorescein diacetate) from cell to blood vessel was greatly diminished when medium K(+) concentration ([K(+)]) was increased 10-fold. These results 1) validate a new approach to the study of choroid plexus function, and 2) indicate a two-step mechanism for transepithelial organic anion transport: indirect coupling of uptake to Na(+) at the apical membrane and electrical potential-driven efflux at the basolateral membrane.

These mutants can be rendered infectious by the addition of soluble receptor-binding domain (RBD) proteins in the culture medium. The RBD proteins that rescue the infectivity of these defective MLV vectors can be derived from the same MLV or from other MLVs that use distinct receptors to mediate entry. We have now constructed functional immunologically reactive gibbon ape leukemia virus (GALV) envelope proteins, tagged with a feline leukemia virus (FeLV)-derived epitope tag, which are efficiently incorporated into infectious particles. Tagged GALV envelope proteins bind specifically to cells expressing the phosphate transporter protein Pit1, demonstrating for the first time that Pit1 is the binding receptor for GALV and not a coreceptor or another type of GALV entry factor. We have also determined that GALV particles bearing SU proteins with an insertion C-terminal to the PHQ motif (GALV I(10)) bind Pit1 but fail to infect cells. Incubation with soluble GALV RBD renders GALV I(10) particles infectious, whereas incubation with soluble RBDs from MLV or FeLV-B does not. This finding is consistent with the results obtained by Lauring et al. using FeLV-T, a virus that employs Pit1 as a receptor but requires soluble FeLV RBD for entry. MLV and GALV RBDs are not able to render FeLV-T infectious (A. S. Lauring, M. M. Anderson, and J. Overbaugh, J. Virol. 75:8888-8898, 2001). Together, these results suggest that fusion-defective FeLV-T and GALV are restricted to homologous RBD rescue of infectivity.

Characterization of a novel cocaine binding site in brain membranes prepared from dopamine transporter knockout mice. AN - 71519246; 11891881 AB - Previous work suggested that the cocaine analog [(125)I]RTI-55 labels a novel binding site in rat brain membranes, which is not associated with the dopamine (DA), serotonin (5-HT), or norepinephrine (NE) transporters [Rothman et al. 1995 J Pharmacol Exp Ther 274:385-395]. Here, we tested whether this site is a product of the DA transporter (DAT) gene. We used a T-antigen knock-in at the DAT gene that results in an effective DAT knock-out (KO) confirmed by Southern blot, DAT immunohistochemistry, and [(125)I]RTI-55 ligand binding. Brain membranes were prepared from frozen whole brain minus caudate of wild-type (WT) B6/Sv129, +/+ and minus sign/minus sign (KO) mice. KO mice were used at approximately 23 days of age. Binding surface analysis of [(125)I]RTI-55 binding to membranes prepared from the brains of WT mice, with 100 nM citalopram to block binding to the 5-HT transporter (SERT), revealed two binding sites: the DAT and a second site, replicating previous studies conducted with rat brains. In the absence of the DAT (minus sign/minus sign mice), binding surface analysis demonstrated that [(125)I]RTI-55 labeled two sites: the NET and a second site called site "X." Structure-activity studies of site "X" demonstrated that high-affinity ligands for the DAT, NET, and SERT have low or negligible affinity for site "X." The relatively high density of site "X" in brain membranes and the fact that the K(i) values of cocaine and cocaethylene for site "X" are in the range achieved in the brain following cocaine administration suggests that site "X" could contribute to the pharmacological or toxicological effects of cocaine. Further progress in delineating the function of site "X" will depend on developing potent and selective agents for this site. JF - Synapse (New York, N.Y.)

There were three main findings: (a) Quality of maternal caregiving was the strongest predictor of cognitive competence, as well as caregivers' ratings of social competence; (b) quality of nonmaternal caregiving was associated with cognitive competence and caregivers' ratings of social competence; and (c) there was a mediated path from both caregiver training and child-staff ratio through quality of nonmaternal caregiving to cognitive competence, as well as to caregivers' ratings of social competence, that was not accounted for entirely by family variables. These findings provide empirical support for policies that improve state regulations for caregiver training and child-staff ratios.

The authors prospectively examined dietary factors hypothesized to be associated with exocrine pancreatic cancer in the Alpha-Tocopherol, Beta-Carotene Cancer Prevention Study cohort in Finland. Of the 27,111 male smokers aged 50-69 years with complete dietary information, as ascertained from a self-administered dietary history questionnaire given at baseline (1985-1988), 163 developed pancreatic cancer from 1985 through November 1997. Cox proportional hazards models were used to estimate smoking- and age-adjusted hazard ratios and 95% confidence intervals. Energy-adjusted butter consumption and saturated fat intake were positively associated with pancreatic cancer (highest quintile vs. lowest: hazard ratio (HR) = 1.40, 95% confidence interval (CI): 0.87, 2.25 (p trend = 0.04), and HR = 1.60, 95% CI: 0.96, 2.64 (p trend = 0.02), respectively). Energy intake and energy-adjusted carbohydrate intake were inversely associated with the disease (highest quintile vs. lowest: HR = 0.62, 95% CI: 0.36, 1.07 (p trend = 0.05), and HR = 0.62, 95% CI: 0.37, 1.03 (p trend = 0.02), respectively). These results support the hypothesis that a high intake of saturated fat may increase the risk of pancreatic cancer in smokers, while greater intakes of energy and carbohydrate may reduce the risk.

Most of the data on global fallout were extracted from the reports of the United Nations Scientific Committee on the Effects of Atomic Radiation, in which the radiation exposures from fallout have been extensively reviewed at regular intervals. United Nations Scientific Committee on the Effects of Atomic Radiation estimated the average effective doses received by the world's population before 2000 to be about 0.4 mSv from external irradiation and 0.6 mSv from internal irradiation, the main radionuclide contributing to the effective dose being super(137)Cs. Effective doses received beyond 2000 result mainly from the environmentally mobile, long-lived super(14)C and amount to about 2.5 mSv summed over present and future generations. Specific information about the doses from fallout received by the United States population is based on the preliminary results of a study requested by the U.S. Congress and conducted jointly by the Centers for Disease Control and Prevention and the National Cancer Institute. Separate calculations were made for the tests conducted at the Nevada Test Site and for the high-yield tests conducted mainly by the United States and the former Soviet Union at sites far away from the contiguous United States (global tests). The estimated average doses from external irradiation received by the United States population were about 0.5 mGy for Nevada Test Site fallout and about 0.7 mGy for global fallout. These values vary little from one organ or tissue of the body to another. In contrast, the average doses from internal irradiation vary markedly from one organ or tissue to another; estimated average thyroid doses to children born in 1951 were about 30 mGy from Nevada Test Site fallout and about 2 mGy from global fallout.

However, in alcoholic hepatitis, the role of polymorphonuclear neutrophils (PMNs) in liver injury still remains to be fully elucidated. Furthermore, the migration of PMNs and their presence in the liver during alcoholic hepatitis have not been fully investigated. Up-regulation of chemokine secretion and adhesion molecule expression on effector cells (i.e., PMNs) and target cells (i.e., hepatocytes) are important factors in neutrophilic infiltration of the liver. The CXC chemokines - that is, interleukin (IL)-8 (in human beings), cytokine-induced neutrophil chemoattractant (CINC) (in rats), and KC (in mice) - are proneutrophilic agents. They are up-regulated during chronic - that is, several years of - alcohol use in human beings and in up to 30 weeks in experimental models of ethanol intoxication in mice and rats. Up-regulation of these chemokines in the circulation and tissues is also associated with enhanced neutrophilic infiltration in the liver. In the rat, the up-regulation of CXC chemokine production is time dependent. For example, after 16 weeks of feeding, up-regulation of CXC chemokine is observed, whereas after 32 weeks, CC chemokines are enhanced. Concomitantly, selective migration of PMNs and mononuclear cells is observed. In another model, in which both CXC and CC chemokines were enhanced after chronic ethanol use for 12 weeks in mice, neutrophilic and mononuclear/lymphocytic infiltrations were also seen. This model correlates closely with alcoholic hepatitis in human beings, characterized by increased IL-8, RANTES (regulated upon activation, normal T cell expressed and secreted), and macrophage inflammatory protein-1 (MIP-1) and profound increases in neutrophils and lymphocytes in the liver.

Alcohol intake is a major cause of hepatitis that may lead to alcoholic cirrhosis - a major cause of death in the United States. In up to one third of heavy drinkers alcoholic hepatitis develops, which is characterized by liver cell death and infiltration of leukocytes in hepatic parenchyma. Although leukocytes have been implicated in the pathogenesis of alcoholic hepatitis, the underlying cellular and molecular mechanisms by which leukocytes migrate to hepatic parenchyma and initiate tissue injury are not clear. For this symposium, 10 speakers were invited to address the following aspects of the mechanisms of alcoholic hepatitis: role of Kupffer cells in initiating the process of alcoholic hepatitis; types of leukocytes involved in the pathogenesis of alcoholic hepatitis; chemokines that are responsible for the attraction of leukocytes; adhesion molecules that promote the attachment of leukocytes to the endothelial cells and hepatocytes; mechanisms of leukocyte transmigration to hepatic parenchyma; mechanisms by which leukocytes initiate tissue injury; and interactive effects of alcohol and hepatitis viral proteins on liver injury. This article provides an introduction to the problem and a summary of the 10 scientific presentations delivered at the symposium.

Several mechanisms have been implicated in exacerbation of liver injury in patients with alcohol drinking and viral hepatitis. These include impairment of host defense and liver regeneration by alcohol consumption. The findings obtained from my laboratory have demonstrated that alcohol potentiates cooperatively several signals activated by hepatitis B virus X protein (HBX) or hepatitis C virus core protein, and HBX sensitizes hepatocytes to tumor necrosis factor-alpha (TNF- alpha )- and ethanol-induced apoptosis by a caspase-3-dependent mechanism, which may also contribute to the synergistic effect of alcohol drinking and viral hepatitis on liver injury.

Salt Lake City (SLC), Utah, and the surrounding intermountain region experienced a resurgence of ARF in 1985 which has persisted. The largest numbers of cases were encountered in 1985-1986 and in 1997-1998. Organisms with a mucoid colony phenotype when grown on blood agar plates were temporally associated with the higher incidence of ARF. To develop an understanding of the molecular population genetic structure of GAS strains associated with ARF in the SLC region, 964 mucoid and nonmucoid pharyngeal isolates recovered in SLC from 1984 to 1999 were studied by sequencing the emm gene. Isolates with an emm18 allele were further characterized by sequencing the spa, covR, and covS genes. Peak periods of ARF were associated with GAS isolates possessing an emm18 allele encoding the protein found in serotype M18 isolates. Among the serotype M18 isolates, the difference in the number of C repeats produced three size variants. Variation was limited in spa, a gene that encodes a streptococcal protective antigen, and covR and covS, genes that encode a two-component regulatory system that, when inactivated, results in a mucoid phenotype and enhanced virulence in mouse infection models. Pulsed-field gel electrophoresis showed a single restriction profile for serotype M18 organisms isolated during both peak periods of ARF. In SLC, the incidence of ARF coresurged with the occurrence of GAS serotype M18 isolates that have very restricted genetic variation.

One property of wild-type AAV-2, that is highly desirable in a gene therapy vector, is its ability to preferentially integrate its DNA into a 4 kilobase region of human chromosome 19, designated AAVS1. One disadvantage of AAV-2 is its relatively small packaging capacity, approximately 4.7 kilobases. Because of this size limitation, the AAV-2 rep and cap genes were removed from first-generation AAV-2-based gene therapy vectors to make room for the therapeutic or marker gene. It was later discovered that the rep gene, or at least one of its products, the Rep68 or Rep78 protein, is required for preferential integration of AAV-2. Recent developments in AAV-2 gene therapy vector construction allow the inclusion of the rep gene into a second generation of AAV-2-based gene therapy systems. These new systems fall into four major categories: plasmid-based systems, co-transduction with multiple AAV-2 vectors, incorporation of the AAV-2 vector into a larger virus, and in vitro packaging. These systems not only allow the inclusion of the rep gene, they also allow the delivery of larger therapeutic genes.

The purpose of the survey was to assess children's potential household exposure to lead, allergens, and bacterial endotoxins. We surveyed a sample of 831 homes, representing 96 million permanently occupied, noninstitutional housing units that permit resident children. We administered questionnaires to household members, made home observations, and took environmental samples. This article provides general background information on the survey, an overview of the survey design, and a description of the data collection and laboratory methods pertaining to the allergen and endotoxin components. We collected dust samples from a bed, the bedroom floor, a sofa or chair, the living room floor, the kitchen floor, and a basement floor and analyzed them for cockroach allergen Bla g 1, the dust mite allergens Der f 1 and Der p 1, the cat allergen Fel d 1, the dog allergen Can f 1, the rodent allergens Rat n 1 and mouse urinary protein, allergens of the fungus Alternaria alternata, and endotoxin. This article provides the essential context for subsequent reports that will describe the prevalence of allergens and endotoxin in U.S. households, their distribution by various housing characteristics, and their associations with allergic diseases such as asthma and rhinitis.

The reproducibility of the process of coupling capture antibodies to microspheres was tested. The use of independently coupled microspheres did not increase the variation of assay results relative to using the same bead set in repeated assays. However, it is necessary to ensure quality control of the coupling process since slight variations in the coupling procedures can profoundly affect the density of capture reagents coupled to the microspheres and consequently adversely affect assay precision. Although the ELISA was more sensitive and did not have the problems with instrument performance encountered with the FlowMetrix assay, the latter was more reproducible, had a greater dynamic range of measurement, and took considerably less preparation time than the ELISA. Greater reproducibility is especially important for measurement of fecal Ig, which is typically highly variable. Thus, in addition to its multi-analyte capability, the FlowMetrix assay system has definite advantages over a conventional ELISA. Mechanical problems such as microspheres settling to the bottom of wells during analysis by an automated plate reader will likely be overcome, and sensitivity improved as this technology develops.

To examine the role of proinflammatory cytokines in the TMT-induced glia response, mixed cortical glia cultures were exposed to TMT and morphological and cytokine responses were examined. Morphological changes in the glia monolayer, enlarged, rounded cell bodies and retraction of the monolayer into distinct GFAP+ dense processes, displayed a dose (1, 5, and 10 mu M TMT) and temporal response (6-48 h), accompanied by clustering of OX-42+ microglia. Tumor necrosis factor- alpha (TNF), interleukin (IL)-1 alpha , and IL-6 mRNA levels were elevated by 3 and 6 h of TMT (10 mu M) and proteins by 24 h. Recombinant proteins for IL-1 alpha (100 pg/ml) and IL-6 (10 ng/ml) exacerbated the morphological response to TMT while those for TNF alpha (150 pg/ml) did not. Neutralizing antibodies (1:100) to IL-1 alpha and IL-6 showed a slight decrease in the severity of the morphological response to TMT while, at 24 h, TNF alpha antibodies (1:100) and an antibody cocktail offered a significant level of protection. At 6 h, the neutralizing antibodies to TNF alpha or IL-1 alpha did not elevate basal cytokine mRNA levels, however, IL-6 and the cocktail of antibodies significantly elevated IL-1 alpha , IL-1 beta , and IL-6 mRNA levels. The specific elevation in IL-1 alpha and IL-6 mRNA levels induced by TMT remained evident only in cells coexposed to anti-TNF alpha . Similar responses in cytokine mRNA levels were seen in cocultures of hippocampal neurons and glia exposed to TMT. These data suggest a relationship between microglia activation, proinflammatory cytokine release, and glia morphological responses, the significance of which remains to be determined, as well as, the impact on neuronal degeneration.

The parS site was inserted into the Escherichia coli chromosome between the promoter and the structural gene for s- galactosidase, lacZ. There was little interference with lacZ expression when ParA and ParB were supplied in trans. However, when a mutant ParA protein, ParAM314I, was supplied along with ParB, expression of lacZ was shut down. ParAM314I, ParB, and parS appear to form a nucleoprotein complex that blocks transcription. Mutations in parA and parB that relieved the parAM314I-dependent block were found. In addition, new mutations which impose the block were selected. Five of the latter mapped to parA and one to parB; all had a propagation-defective phenotype (Par super(PD)) similar to that of parAM314I. Thus, whereas a null par mutant P1 plasmid segregates its DNA randomly, these mutants prevent even random distribution of the plasmid. We propose that ParA protein normally interacts transiently with the ParB-parS complex for partition to proceed but that the mutations block ParA dissociation. This "permanent" ParA-ParB-parS complex acts as a transcription block. Consistent with this hypothesis, we found that three of the seven blocking mutations lie within regions of ParA and ParB that are known to interact with each other. When the transcription block is imposed, regional silencing of nearby genes occurs.

The nuclear tests were conducted by five nations (United States, Soviet Union, United Kingdom, France, and China) primarily at 16 sites. The 16 testing sites, located in nine different countries on five continents (plus Oceania) contributed nearly all of the radioactive materials released to the environment by atmospheric testing; only small amounts were released at a few other minor testing sites. The 16 sites discussed here are Nevada Test Site, USA (North American continent), Bikini and Enewetak, Marshall Islands (Oceania); Johnston Island, USA (Oceania), Christmas and Malden Island, Kiribati (Oceania); Emu Field, Maralinga, and Monte Bello Islands, Australia (Australian continent); Mururoa and Fangataufa, French Polynesia (Oceania), Reggane, Algeria (Africa), Novaya Zemlya and Kapustin Yar, Russia (Europe), Semipalatinsk, Kazakhstan (Asia), and Lop Nor, China (Asia). There were large differences in the numbers of tests conducted at each location and in the total explosive yields. Those factors, as well as differences in population density, lifestyle, environment, and climate at each site, led to large differences in the doses received by local populations. In general, the tests conducted earliest led to the highest individual and population exposures, although the amount of information available for a few of these sites is insufficient to provide any detailed evaluation of radiation exposures. The most comprehensive information for any site is for the Nevada Test Site. The disparities in available information and difficulty to determining the radiation exposures of local populations at each site. It is the goal of this paper to summarize the available information on external and internal doses received by the public living in the regions near each of the mentioned nuclear test sites as a consequence of local fallout deposition.

The potential regions of intermolecular RNA-RNA hybridization, or clinger fragments, in 16S rRNA, which are complementary to the sites frequently occurring in mRNAs and tRNAs, were found. Major clinger fragments on 16S rRNA are universal for genes that belong to different functional groups. Our results show there are adaptations of the structural organization of the 16S rRNA molecule to messenger and transport RNA sequences. RNA interaction with clinger fragments may contribute to upregulation of the translation process through increasing the local concentration of mRNAs and tRNAs in the vicinity of the ribosome and their proper positioning, as well as decrease the efficiency of translation through nonspecific mRNA-16SrRNA interactions.

AN - 72796848; 12509250 AB - We had shown previously that DNA polymerase beta (beta-pol) null mouse fibroblasts, deficient in base excision repair (BER), are hypersensitive to monofunctional methylating agents but not to hydrogen peroxide (H2O2). This is surprising because beta-pol is thought to be involved in BER of oxidative as well as methylated DNA damage. We confirm these findings here in early-passage cells. However, with time in culture, beta-pol null cells become hypersensitive to H2O2 and other reactive oxygen species-generating agents. Analysis of in vitro BER reveals a strong deficiency in single-nucleotide BER of 8-oxoguanine (8-oxoG) by both early- and late-passage beta-pol null cell extracts. Therefore, in early-passage wild-type and beta-pol null cells, the capacity for single-nucleotide BER of 8-oxoG does not correlate with cellular sensitivity to H2O2. Expression of beta-pol protein in the late-passage null cells almost completely reverses the H2O2-hypersensitivity phenotype. Methoxyamine (MX) treatment sensitizes late-passage wild-type cells to H2O2 as expected for beta-pol-mediated single-nucleotide BER; however in beta-pol null cells, MX has no effect. The data indicate a role(s) of beta-pol-dependent repair in protection against the cytotoxicity of oxidative DNA damage in wild-type cells.

AN - 71627069; 11825902 AB - We have cloned the complete cDNA from mouse paxillin, a 68-kDa adapter protein found in focal adhesions. We found that paxillin was degraded by caspases in Ba/F3 cell apoptosis induced by withdrawal of interleukin-3 (IL-3), a survival factor for this cell, and by ionizing radiation. Also, paxillin was degraded in vitro by incubation with recombinant caspase-3. Western blot analyses of degradation products of overexpressed green fluorescence protein-tagged paxillin and site-specific mutants demonstrated that Asp-102 and Asp-301 were early caspase cleavage sites, and Asp-5, Asp-146, Asp-165, and Asp-222 were late cleavage sites. Overexpression of paxillin delayed apoptosis of Ba/F3 after IL-3 withdrawal. Furthermore, this anti-apoptotic effect of paxillin was augmented by a triple mutation in aspartic acids at caspase cleavage sites. These results suggest that paxillin plays a critical role in cell survival signaling and that the cleavage of paxillin by caspases might be an important event for focal adhesion disassembly during cell apoptosis, contributing to detachment, rounding, and death.

We find that onconase enters living mammalian cells and selectively cleaves tRNA with no detectable degradation of rRNA. The RNA specificity of onconase in vitro using reticulocyte lysate and purified RNA substrates indicates that proteins associated with rRNA protect the rRNA from the onconase ribonucleolytic action contributing to the cellular tRNA selectivity of onconase. The onconase-mediated tRNA degradation in cells appears to be accompanied by increased levels of tRNA turnover and induction of tRNA synthesis perhaps in response to the selective toxin-induced loss of tRNA. Degradation products of tRNA sub(3) super(Lys), which acts as a primer for HIV-1 replication, were clearly detected in cells infected with HIV-1 and treated with sublethal concentrations of onconase. However, a new synthesis of tRNA sub(3) super(Lys) also seemed to occur in these cells resulting in plateauing of the steady-state levels of this tRNA. We conclude that the degradation of tRNAs may be a primary factor in the cytotoxic activity of onconase.

It has been suggested that the dissociation is not the immediate cause of termination but is preceded by catalytic inactivation of the elongation complex. In vitro reducing ionic strength can be used to stabilize very unstable and catalytically inactive complex at the point of termination; the previous biochemical characterization of this complex has led to important conclusions regarding termination mechanism. Here we analyze in detail the complexes formed between DNA template, nascent RNA, and Escherichia coli RNA polymerase during transcription through the tR2 terminator of bacteriophage lambda . At low ionic strength, the majority of elongation complexes fall apart upon reaching the terminator. Released RNA and DNA efficiently rebind RNA polymerase (RNAP) and form binary RNAP super(.)RNA and RNAP super(.)DNA complexes, which are indistinguishable from binary complexes obtained by direct mixing of the purified nucleic acids and the enzyme. A small fraction of elongation complexes that reach termination point escapes dissociation because RNA polymerase has backtracked from the terminator to an upstream DNA position. Thus, transcription elongation to a terminator site produces no termination intermediates that withstand dissociation in the time scale appropriate for biochemical studies.

Here, a plasmid-encoded phospholipase D (PLD), previously characterized as Yersinia murine toxin (Ymt), was shown to be required for survival of Y. pestis in the midgut of its principal vector, the rat flea Xenopsylla cheopis. Intracellular PLD activity appeared to protect Y. pestis from a cytotoxic digestion product of blood plasma in the flea gut. By enabling colonization of the flea midgut, acquisition of this PLD may have precipitated the transition of Y. pestis to obligate arthropod-borne transmission.

The subjects were monitored with respect to vesicle formation (an indicator of successful vaccination), the viral titer at the time of peak lesion formation, antiviral antibodies, and cellular immune responses. A vaccinia vesicle developed in 19 of the 20 subjects who received undiluted vaccine (95 percent), 14 of the 20 who received the 1:10 dilution (70 percent), and 3 of the 20 who received the 1:100 dilution (15 percent). One month after vaccination, 34 of 36 subjects with vesicles had antibody responses, as compared with only 1 of 24 subjects without clinical evidence of vaccinia virus replication. Vigorous cytotoxic T-cell and interferon-gamma responses occurred in 94 percent of subjects with vesicles, and a cytotoxic T-cell response occurred in only one subject without a vesicle. The vaccinia virus vaccine (which was produced in 1982 or earlier) still has substantial potency when administered by a bifurcated needle to previously unvaccinated adults. Diluting the vaccine reduces the rate of successful vaccination. The development of vesicular skin lesions after vaccination correlates with the induction of the antibody and T-cell responses that are considered essential for clearing vaccinia virus infections.

With no natural reservoir, variola virus, which causes smallpox, has existed only in laboratories; indeed, the last case of smallpox was due to infection acquired in a laboratory in the United Kingdom in 1978. During the global program of smallpox eradication, the World Health Organization (WHO) made concerted efforts to decrease the number of laboratories retaining variola virus. On the basis of contacts with all countries and a total of 823 microbiology institutions, 76 such laboratories had been identified by 1978. By 1984, only the Centers for Disease Control and Prevention (CDC), in Atlanta, and the Research Institute of Viral Preparations, in Moscow, retained variola virus isolates. In 1994, the Russian isolates were moved to the State Research Center of Virology and Biotechnology (the Vektor Institute), in Novosibirsk, Russia. There is concern that variola virus resides outside these laboratories and could be used as a weapon by terrorists. Possible sources are virus in countries that claim that they destroyed their stocks but did not and virus acquired from laboratories in the former Soviet Union. An accidental or deliberate release of smallpox could cause a major epidemic. Because vaccination against smallpox has not been performed routinely in the United States since 1972 and in the rest of the world since about 1982, there is now a large population of susceptible persons. Thus, if an outbreak occurred, prompt recognition and institution of control measures would be important.

AN - 71808806; 12062409 AB - A structural and thermodynamic characterization of 5F-Trp-substituted immunoglobulin binding domain B1 of streptococcal protein G (GB1) was carried out by nuclear magnetic resonance and circular dichroism spectroscopy. A single fluorine reporter atom was positioned at the center of the three-dimensional structure, uniquely poised to be exploited for studying interior properties of this protein. We demonstrate that the introduction of 5F-Trp does not affect the global and local architecture of GB1 and has no influence on the thermodynamic stability. The favorable properties of the fluorinated GB1 render this molecule a desirable model system for the development of spectroscopic methodology and theoretical calculations.

AN - 71728232; 12034501 AB - DLC-1 (deleted in liver cancer 1) is a candidate tumor suppressor gene for hepatocellular carcinoma and other cancers. It is the human homologue of rat p122, which has been shown to function as a GTPase activating protein for RhoA, and it may be involved in signal transduction pathways regulating cell proliferation and adhesion. To establish an animal model for studying the regulation and function of DLC-1, we have undertaken the characterization of the mouse DLC-1 gene. Northern blot analysis shows that the mouse DLC-1 mRNA is widely expressed, with the highest levels in heart, liver, and lung. Mouse genomic clones that contain the entire DLC-1 gene of 47 kb were isolated. The mouse gene consists of 14 exons, and the structural organization is highly similar to that of the human gene. The promoter region of the mouse gene was GC-rich and contained potential binding sites for transcription factors SP1, GCF, and AP-2. A polymorphic microsatellite marker in intron 8 was used for mapping the gene (Arhgap7) to 20 cM on mouse chromosome 8 and for allelotyping of mouse liver tumor DNAs.

AN - 71614883; 11960002 AB - Vlad tepes (vlt(m651)) is one of only five "bloodless" zebrafish mutants isolated through large-scale chemical mutagenesis screening. It is characterized by a severe reduction in blood cell progenitors and few or no blood cells at the onset of circulation. We now report characterization of the mutant phenotype and the identification of the gene mutated in vlt(m651). Embryos homozygous for the vlt(m651) mutation had normal expression of hematopoietic stem cell markers through 24 h postfertilization, as well as normal expression of myeloid and lymphoid markers. Analysis of erythroid development revealed variable expression of erythroid markers. Through positional and candidate gene cloning approaches we identified a nonsense mutation in the gata1 gene, 1015C --> T (Arg-339 --> Stop), in vlt(m651). The nonsense mutation was located C-terminal to the two zinc fingers and resulted in a truncated protein that was unable to bind DNA or mediate GATA-specific transactivation. A BAC clone containing the zebrafish gata1 gene was able to rescue the bloodless phenotype in vlt(m651). These results show that the vlt(m651) mutation is a previously uncharacterized gata1 allele in the zebrafish. The vlt(m651) mutation sheds new light on Gata1 structure and function in vivo, demonstrates that Gata1 plays an essential role in zebrafish hematopoiesis with significant conservation of function between mammals and zebrafish, and offers a powerful tool for future studies of the hematopoietic pathway.

AN - 71613200; 11917138 AB - An improved understanding of the evolution of gene function at the molecular level may provide significant insights into the origin of biological novelty and adaptation. With the approach of ancestral protein reconstruction, we here address the question of how a dramatically enhanced ribonucleolytic activity and the related antiviral activity evolved in a recently duplicated ribonuclease (eosinophil-derived neurotoxin) gene of higher primates. We show that the mother gene of the duplicated genes had already possessed a weak antiviral activity before duplication. After duplication, substitutions at two interacting sites (Arg-64-->Ser and Thr-132-->Arg) resulted in a 13-fold enhancement of the ribonucleolytic activity of eosinophil-derived neurotoxin. These substitutions are also necessary for the potent antiviral activity, with contributions from additional amino acid changes at interacting sites. Our observation that a change in eosinophil-derived neurotoxin function occurs only when both interacting sites are altered indicates the importance of complementary substitutions in protein evolution. Thus, neutral substitutions are not simply "noises" in protein evolution, as many have thought. They may play constructive roles by setting the intramolecular microenvironment for further complementary advantageous substitutions, which can lead to improved or altered function. Overall, our study illustrates the power of the "paleomolecular biochemistry" approach in delineating the complex interplays of amino acid substitutions in evolution and in identifying the molecular basis of biological innovation.

AN - 71588069; 11948661 AB - The bone morphogenetic proteins (BMPs) play an inductive role in the generation of cerebellar granule cells embryonically. Therefore, we chose to look at their effects on cerebellar granule cell survival and differentiation postnatally. The cells express mRNA for both BMP-6 and BMP-7, as well as for the receptors BMPRIA and BMPRII, demonstrating that the postnatal cells have the ability to form the heterodimer receptors needed to respond to BMPs. BMP-7 promotes cell survival, with a maximal effect at 10 ng/ml, whereas tenfold more BMP-6 is needed: Both were active over the course of 8 days in culture. In addition, both BMPs were able to protect the neurons against death from induced apoptosis (exposure to serum-free, low-potassium medium) or exposure to glutamate. However, only BMP-6 could stimulate neurite outgrowth, measured with a neurofilament ELISA, an effect that was seen over the first 6 days in culture. These results, taken together with others in the literature, suggest that the BMPs have strong neurotrophic effects that are both neuron specific and BMP specific. Published 2002 Wiley-Liss, Inc.

AN - 71577886; 11929754 AB - We hypothesized that incremental improvements in the cyclophosphamide-doxorubicin-vincristine-prednisone (CHOP) chemotherapy regimen through optimization of drug selection, schedule, and pharmacokinetics would improve outcome in patients with large B-cell lymphomas. A prospective multi-institutional study of administration of etoposide, vincristine, and doxorubicin for 96 hours with bolus doses of cyclophosphamide and oral prednisone (EPOCH therapy) was done in 50 patients with previously untreated large B-cell lymphomas. The doses of etoposide, doxorubicin, and cyclophosphamide were adjusted 20% each cycle to achieve a nadir absolute neutrophil count below 0.5 x 10(9)/L. The median age of the patients was 46 years (range, 20-88 years); 24% were older than 60 years; and 44% were at high-intermediate or high risk according to International Prognostic Index (IPI) criteria. There was a complete response in 92% of patients, and at the median follow-up time of 62 months, the progression-free survival (PFS) and overall survival (OS) rates were 70% and 73%, respectively. Neither IPI risk factors nor the index itself was associated with response, PFS, or OS. Doses were escalated in 58% of cycles, and toxicity levels were tolerable. Significant inverse correlations were observed between dose intensity and age for all adjusted agents, and drug clearance of doxorubicin and free etoposide was also inversely correlated with age (r = -0.54 and P(2) =.08 and r = -0.45 and P(2) =.034, respectively). Free-etoposide clearance increased significantly during successive cycles (P(2) =.015). Lymphomas with proliferation of at least 80% had somewhat lower progression and those expressing bcl-2 had significantly higher progression (P(2) =.04). Expression of bcl-2 may discriminate the recently described activated B-like from germinal-center B-like large-cell lymphomas and provide important pathobiologic and prognostic information. Dose-adjusted EPOCH may produce more cell kill than CHOP-based regimens. Dynamic dose adjustment may overcome inadequate drug concentrations, particularly in younger patients, and compensate for increased drug clearance over time.

AN - 71571321; 11931653 AB - Sulphonation is a fundamental process that is essential for normal growth and development as well as maintenance of the internal milieu. The universal sulphonate donor molecule essential for all sulphoconjugation reactions is adenosine 3'-phosphate 5'-phosphosulphate (PAPS), which is produced from ATP and inorganic sulphate by the action of bifunctional PAPS synthase. There are two isozymes encoded by genes located on chromosome 4 (PAPS synthase 1) and chromosome 10 (PAPS synthase 2). The promoter for PAPS synthase 2 contains neither a TATAAA nor a CCAAT box, although a consensus initiator motif is present. Three human cell lines were used to examine promoter activity after transfection with various lengths of the 5'-flanking region of the PAPS synthase 2 gene fused to a reporter gene. Proximal promoter activity was located between bp -84 and bp -124 upstream of the purported transcription start site. This region contains two GC/GT boxes that are essential for full promoter activity, as indicated by deletion analysis and supported further by mutagenesis. A nuclear extract of SW13 cells, which highly express PAPS synthase 2, contained proteins that bound to probes possessing promoter-specific GC/GT boxes. Furthermore, the presence of specificity protein (Sp) 1, Sp2 and Sp3 proteins in the nuclear extract was confirmed by supershift analysis. Co-transfection experiments using SL2 cells yielded additional support for the involvement of Sp1 in transcriptional regulation of the PAPS synthase 2 gene; the involvement of Sp2 and/or Sp3 remains to be clarified further.

AN - 71556966; 11921362 AB - Adrenomedullin (AM) is a pluripotent regulatory peptide initially isolated from a human pheochromocytoma (adrenal tumor) and subsequently shown to play a critical role in cancer cell division, tumor neovascularization, and circumvention of programmed cell death, thus it is an important tumor cell survival factor underlying human carcinogenesis. A variety of neural and epithelial cancers have been shown to produce abundant amounts of AM. Recent findings have implicated elevation of serum AM with the onset of malignant expression. In addition, patients with tumors producing high levels of this peptide have a poor prognostic clinical outcome. Given that most human epithelial cancers display a microenvironment of reduced oxygen tension, it is interesting to note that AM and several of its receptors are upregulated during hypoxic insult. The existence of such a regulatory pathway has been implicated as the basis for the overexpression of AM/AM-R in human malignancies, thereby generating a subsequent autocrine/paracrine growth advantage for the tumor cell. Furthermore, AM has been implicated as a potential immune suppressor substance, inhibiting macrophage function and acting as a newly identified negative regulator of the complement cascade, protective properties which may help cancer cells to circumvent immune surveillance. Hence, AM's traditional participation in normal physiology (cited elsewhere in this issue) can be extended to a primary player in human carcinogenesis and may have clinical relevance as a biological target for the intervention of tumor progression.

AN - 71550467; 11915002 AB - The objective of the present study was to characterize the genitourinary syndromes that accompany indinavir-associated pyuria. Of 23 indinavir-treated patients with persistent pyuria, 4 had isolated interstitial nephritis, 10 had both interstitial nephritis and urothelial inflammation, 7 had isolated urothelial inflammation, and 2 had pyuria with nonspecific urinary tract inflammation. A total of 21 patients had multinucleated histiocytes identified by cytologic testing of urine specimens. Urine abnormalities resolved in all 20 patients who stopped receiving indinavir therapy. Pyuria continued in the 3 patients who continued receiving indinavir. Six patients had elevated serum creatinine levels, which returned to baseline levels when indinavir was discontinued. In conclusion, indinavir-associated pyuria was frequently associated with evidence of interstitial nephritis and/or urothelial inflammation, multinucleated histiocytes were commonly present in urine specimens, and cessation of indinavir therapy was associated with prompt resolution of urine abnormalities.

AN - 71638950; 11944919 AB - Mutant proteins with altered properties can be useful probes for investigating structure, ligand binding sites, mechanisms of action, and physicochemical attributes of the corresponding wild-type proteins of interest. In this report, we illuminate properties of mutants of the potent HIV-inactivating protein, cyanovirin-N (CV-N), selected by construction of a mutant library by error-prone polymerase chain reaction and affinity-based screening using T7 phage display technology. After three rounds of biopanning, two phage-displayed, one-point mutants of CV-N, Ser52Pro and Ala77Thr, were isolated. After the elucidation of biological activities of the mutants displayed on phage as well as the Escherichia coli-expressed, purified mutant proteins, we subsequently subjected the mutants to analyses by native PAGE and size-exclusion chromatography. We found that the Ser52Pro mutant not only was active against HIV but also existed exclusively as a dimer in solution. This was in marked contrast to the wild-type CV-N, which exists in solution predominantly as the monomer. The Ser52Pro mutant provides a novel model for further investigations of the folding mechanism as well as structure-activity requirements for CV-N's antiviral properties.

AN - 71589014; 11939710 AB - Tissue-specific induction of cytochrome P-450s (CYP) followed by increased in situ bioactivation may contribute to chemical-induced site-specific toxicity. In rats, methacrylonitrile (MAN) is metabolized by cytochrome P-450 2E1 (CYP2E1) to acetone, which is eliminated along with parent MAN in breath. Gavage administration of MAN to rats causes olfactory epithelial damage and liver enlargement. It was hypothesized that treatment of rats with MAN may result in differential expression of CYP2E1 in tissues leading to tissue-specific toxicity via increased in situ formation of cytotoxic MAN metabolites. In this study, male F344 rats received 60 mg MAN/kg and were sacrificed 6, 12, or 24 h after a single dose, or 24 h after 7 consecutive daily doses. Liver, lung, and nasal tissues were collected. Reverse-transcription polymerase chain reaction (RT-PCR), Western blotting, and immunohistochemical staining were used to assess CYP2E1 expression and localization, and chlorzoxazone hydroxylation was used as a measure of CYP2E1 catalytic activity. Present results showed that CYP2E1 mRNA was increased in lung and nasal tissues with minimal effects in liver of MAN-treated rats. Induction of CYP2E1 protein expression was detected in lung. CYP2E1 activity was higher in liver and lung microsomes from MAN-treated rats when compared to control animals. To compare the effects of MAN and acetone, male F344 rats received a single acetone dose (5 ml/kg) by gavage. After 12 h, acetone treatment resulted in a significant increase in the levels of CYP2E1 mRNA and protein in lung and nasal tissues, with no obvious change noted in the liver. Overall, these data suggest that administration of MAN to rats causes increased expression of CYP2E1 in lung, liver, and nasal tissues. These results also show that acetone induces the expression of CYP2E1 at both the mRNA and protein levels in rat nasal and lung tissues. In conclusion, MAN increased the expression of CYP2E1, and this effect varied as a function of time, length of exposure, and tissue examined. While the damage in the olfactory mucosa due to MAN treatment may not be explained by the observed induction of CYP2E1, it is possible that other CYPs may play a role in the in situ bioactivation of MAN.

AN - 71581058; 11812797 AB - The EC(50) of agonists and the partial agonist activity of antagonists are crucial parameters for steroid hormone control of gene expression and endocrine therapies. These parameters have been shown to be modulated by a naturally occurring cis-acting element, called the glucocorticoid modulatory element (GME) that binds two proteins, GMEB-1 and -2. We now present evidence that the GMEBs contact Ubc9, which is the mammalian homolog of a yeast E2 ubiquitin-conjugating enzyme. Ubc9 also binds to glucocorticoid receptors (GRs). Ubc9 displays no intrinsic transactivation activity but modifies both the absolute amount of induced gene product and the fold induction by GR. With high concentrations of GR, added Ubc9 also reduces the EC(50) of agonists and increases the partial agonist activity of antagonists in a manner that is independent of the ability of Ubc9 to transfer SUMO-1 (small ubiquitin-like modifier-1) to proteins. This new activity of Ubc9 requires only the ligand binding domain of GR and part of the hinge region. Interestingly, Ubc9 modulation of full-length GR transcriptional properties can be seen in the absence of a GME. This, though, is consistent with the GME acting by increasing the local concentration of Ubc9, which then activates a previously unobserved target in the transcriptional machinery. With high concentrations of Ubc9 and GR, Ubc9 binding to GR appears to be sufficient to permit Ubc9 to act independently of the GME.

After an average of 10 years of follow-up, 1,442 lung cancer cases were diagnosed. Cox proportional hazards models were used to estimate the relative risk (RR) and 95% confidence intervals (CI) of lung cancer associated with self-reported occupational and leisure-time activity, adjusted for age, supplement group, body mass index, cigarettes smoked daily, years of smoking, education, energy intake and vegetable intake. There were no associations between occupational, leisure-time or combined categories of physical activity with lung cancer risk; however, age appeared to modify the effect of leisure-time activity (p = 0.02). Within increasing quartiles of age, the RRs (CI) for men active in leisure time compared to sedentary men were 0.77 (0.54-1.09), 0.74 (0.57-0.95), 1.09 (0.89-1.33) and 1.03 (0.88-1.21). These data suggest that among smokers, neither occupational nor leisure-time activity is associated with lung cancer risk. There may, however, be some modest risk reduction associated with leisure activity among younger smokers.

AN - 71530894; 11897129 AB - Recombinant iron-containing superoxide dismutase (Fe-SOD) from Plasmodium falciparum was produced in a SOD-deficient strain of Escherichia coli, purified and characterised. The enzyme is a dimer, which contains 1.7 Fe equivalents and is sensitive to hydrogen peroxide (H(2)O(2)). Electron paramagnetic resonance (EPR) analysis showed two different signals, reflecting the presence of two different types of high-spin Fe sites with different symmetries. The role of the W71 residue during inactivation by H(2)O(2) of the P. falciparum Fe-SOD was studied by site-directed mutagenesis. First, the W71V mutation led to a change in the relative proportion of the two Fe-based EPR signals. Second, the mutant protein was almost as active as the wild-type (WT) protein but more sensitive to heat inactivation. Third, resistance to H(2)O(2) was only slightly increased indicating that W71 was marginally responsible for the sensitivity of Fe-SOD to H(2)O(2). A molecular model of the subunit was designed to assist in interpretation of the results. The fact that the parasite SOD does not belong to classes of SOD present in humans may provide a novel approach for the design of antimalarial drugs.

AN - 71682891; 12013548 AB - The US Environmental Protection Agency (EPA) National Center for Environmental Assessment is engaged in the development of a methodology for Agency use to perform risk assessments for non-cancer effects due to acute inhalation exposures. The methodology will provide general guidance for deriving chemical-specific acute exposure benchmarks called acute reference exposures (AREs). Chemical-specific AREs are analogous to reference concentra tions (RfCs) for chronic non-cancer effects and will be incorporated in chemical-specific files in the US EPA's Integrated Risk Information System (IRIS) as they are developed and reviewed. AREs will have wide applicability in assessing the potential health risks of accidental and routine acute releases of chemicals to the environment. The proposed methodology for ARE development provides a framework for choosing an optimal derivation approach, depending on the type of data available, from the no-observed-adverse-effect level (NOAEL), benchmark concentration (BMC), or categorical regression approaches. Uncertainty factors are applied to the point of departure, determined by one of the recommended approaches, to derive the ARE. Due to the capability to use more exposure-response information than the NOAEL approach allows, exposure-response analyses such as BMC and categorical regression are favored as methods to develop the point of departure when the available database will support such analyses. The NOAEL approach is suitable when the data are insufficient to support exposure-response modeling. Applications of the proposed ARE methodology are illustrated by the derivation of example AREs for hydrogen sulfide and hexachlorocyclopentadiene, which showcase the categorical regression and NOAEL approaches, respectively. In addition, a recent review of the proposed ARE methodology by the US EPA Risk Assessment Forum is discussed.

AN - 71451147; 11849736 AB - Previous studies have shown that pentachlorophenol (PCP) has both potentiative and antagonistic effects on the genotoxicity of benzo[a]pyrene (B[a]P). It has been suggested that these effects are due to inhibition and/or induction of enzymes involved in the biotransformation of B[a]P [Carcinogenesis 16 (1995) 2643]. However, B[a]P [J. Biol. Chem. 274 (1999) 35240] and a metabolite of PCP, tetrachlorohydroquinone (TCHQ) [Chem. Biol. Interact. 105 (1997) 1], induce p53 protein synthesis in vitro. To investigate this effect further, C57BL/6Tac trp53+/+ (wild-type, WT) and C57BL/6Tac trp53-/- (knockout, KO) mice were exposed to 55 microg B[a]P/g BW alone or in combination with 25 microg/g PCP. Hepatic and lung DNA were analyzed for the major B[a]P DNA adduct, 7R,8S,9S-trihydroxy-10R-(N2-2'-deoxyguanosyl)-7,8,9,10-tetrahydro-B[a]P (BPDE-N2G) and other minor adducts using the 32P-postlabeling assay. BPDE-N2G adducts were detected in all animals exposed to B[a]P. Similar adduct levels were observed in WT mice exposed to 55 microg/g B[a]P compared with KO mice exposed to B[a]P alone or in combination with PCP. Interestingly, hepatic and lung BPDE-N2G adducts were decreased in WT mice exposed to B[a]P with PCP (P<0.05). Total DNA adducts in the liver (P<0.05) were also decreased in WT mice exposed to B[a]P and PCP. Total DNA adducts in either hepatic or lung DNA isolated from KO mice were not different in mice treated with PCP and B[a]P. These results suggest that the decrease in BPDE-N2G adducts observed in WT mice may be a result of p53 accumulation or induction of repair pathways in response to damage induced by PCP.

AN - 71572839; 11821420 AB - Human DNA polymerase eta was used to copy four stereoisomeric deoxyguanosine (dG) adducts derived from benzo[a]pyrene 7,8-diol 9,10-epoxide (diastereomer with the 7-hydroxyl group and epoxide oxygen trans (BaP DE-2)). The adducts, formed by either cis or trans epoxide ring opening of each enantiomer of BaP DE-2 by N(2) of dG, were placed at the fourth nucleotide from the 5'-end in two 16-mer sequence contexts, 5' approximately CG*A approximately and 5' approximately GG*T. poleta was remarkably error prone at all four diol epoxide adducts, preferring to misincorporate G and A at frequencies 3- to more than 50-fold greater than the frequencies for T or the correct C, although the highest rates were 60-fold below the rate of incorporation of C opposite a non-adducted G. Anti to syn rotation of the adducted base, consistent with previous NMR data for a BaP DE-2 dG adduct placed just beyond a primer terminus, provides a rationale for preferring purine misincorporation. Extension of purine misincorporations occurred preferentially, but extension beyond the adduct site was weak with V(max)/K(m) values generally 10-fold less than for misincorporation. Mostly A was incorporated opposite (+)-BaP DE-2 dG adducts, which correlates with published observations that G --> T is the most common type of mutation that (+)-BaP DE-2 induces in mammalian cells.

AN - 71560900; 11812791 AB - Protein kinase C delta (PKC delta) is tyrosine-phosphorylated and catalytically inactive in mouse keratinocytes transformed by a ras oncogene. In several other model systems, Src kinases are upstream regulators of PKC delta. To examine this relationship in epidermal carcinogenesis, v-ras transformed mouse keratinocytes were treated with a selective Src kinase inhibitor (PD 173958). PD 173958 decreased autophosphorylation of Src, Fyn, and Lyn kinases and prevented tyrosine phosphorylation of the Src kinase substrate p120. PD 173958 also prevented PKC delta tyrosine phosphorylation and activated PKC delta as detected by membrane translocation. Expression of keratinocyte differentiation markers increased in PD 173958-treated v-ras-keratinocytes, and fluid-filled domes emerged, indicative of tight junction formation. Antisense PKC delta or bryostatin 1 inhibited dome formation, while overexpression of PKC delta in the presence of PD 173958 enhanced the formation of domes. Plasmids encoding phenylalanine mutants of PKC delta tyrosine residues 64 and 565 induced domes in the absence of PD 173958, while phenylalanine mutants of tyrosine residues 52, 155, and 187 were inactive. Thus, Src kinase mediated post-translational modification of PKC delta on specific tyrosine residues in ras-transformed mouse keratinocytes inactivates PKC delta and contributes to alterations in the differentiated phenotype and tight junction formation associated with neoplasia.

Surface enhanced laser desorption/ionization time-of-flight mass spectrometry (SELDI-TOF MS) is a novel approach to biomarker discovery that combines two powerful techniques: chromatography and mass spectrometry. One of the key features of SELDI-TOF MS is its ability to provide a rapid protein expression profile from a variety of biological and clinical samples. It has been used for biomarker identification as well as the study of protein-protein, and protein-DNA interaction. The versatility of SELDI-TOF MS has allowed its use in projects ranging from the identification of potential diagnostic markers for prostate, bladder, breast, and ovarian cancers and Alzheimer's disease, to the study of biomolecular interactions and the characterization of posttranslational modifications. In this minireview we discuss the application of SELDI-TOF MS to protein biomarker discovery and profiling.

AN - 71561731; 11916396 AB - The anti-HIV cyanobacterial protein cyanovirin-N can undergo domain swapping to form an intertwined dimer. The dimeric form is stable at low pH and millimolar concentrations. By deleting an amino acid from the hinge linker about which domain swapping occurs, we have constructed an obligate domain-swapped dimer of cyanovirin-N that represents a new tetravalent carbohydrate binding protein that is stable over a large range of pH values. This obligate dimer displays enhanced anti-HIV activity relative to the wild-type cyanovirin-N monomer with an observed 3.5-fold decrease in IC(50) (9nM for the dimer vs 32 nM for the monomer) for inhibition of HIV-1 envelope-mediated cell fusion and, when expressed in Escherichia coli, can be rapidly obtained in >98% purity in a single chromatographic step.

The presence of NADH was not required to observe of these inter-ligand Overhauser effects. A model for the ternary complex was developed in which the methylbenzamide inhibitors bind to the hydrophobic pocket of the active site involved in benzyl alcohol binding, while the cyanoborohydride coordinates directly with Zn super(2+) at the active site. The observation of these effects supports the use of inter-ligand Overhauser effects for the identification of unanticipated ternary complexes that are of potential utility for the development of novel enzyme inhibitors.

The RyhB 90-nt RNA down-regulates a set of iron- storage and iron-using proteins when iron is limiting; it is itself negatively regulated by the ferric uptake repressor protein, Fur (Ferric uptake regulator). RyhB RNA levels are inversely correlated with mRNA levels for the sdhCDAB operon, encoding succinate dehydrogenase, as well as five other genes previously shown to be positively regulated by Fur by an unknown mechanism. These include two other genes encoding enzymes in the tricarboxylic acid cycle, acnA and fumA, two ferritin genes, ftnA and bfr, and a gene for superoxide dismutase, sodB. Fur positive regulation of all these genes is fully reversed in an ryhB mutant. Our results explain the previously observed inability of fur mutants to grow on succinate. RyhB requires the RNA-binding protein, Hfq, for activity. Sequences within RyhB are complementary to regions within each of the target genes, suggesting that RyhB acts as an antisense RNA. In sdhCDAB, the complementary region is at the end of the first gene of the sdhCDAB operon; full-length sdhCDAB message disappears and a truncated message, equivalent in size to the region upstream of the complementarity, is detected when RyhB is expressed. RyhB provides a mechanism for the cell to down-regulate iron-storage proteins and nonessential ironcontaining proteins when iron is limiting, thus modulating intracellular iron usage to supplement mechanisms for iron uptake directly regulated by Fur.

The molecular basis of ARF and the subsequent rheumatic heart disease are poorly understood. Serotype M18 GAS strains have been associated for decades with ARF outbreaks in the U.S. As a first step toward gaining new insight into ARF pathogenesis, we sequenced the genome of strain MGAS8232, a serotype M18 organism isolated from a patient with ARF. The genome is a circular chromosome of 1,895,017 bp, and it shares 1.7 Mb of closely related genetic material with strain SF370 (a sequenced serotype M1 strain). Strain MGAS8232 has 178 ORFs absent in SF370. Phages, phage-like elements, and insertion sequences are the major sources of variation between the genomes. The genomes of strain MGAS8232 and SF370 encode many of the same proven or putative virulence factors. Importantly, strain MGAS8232 has genes encoding many additional secreted proteins involved in human-GAS interactions, including streptococcal pyrogenic exotoxin A (scarlet fever toxin) and two uncharacterized pyrogenic exotoxin homologues, all phage-associated. DNA microarray analysis of 36 serotype M18 strains from diverse localities showed that most regions of variation were phages or phage-like elements. Two epidemics of ARF occurring 12 years apart in Salt Lake City, UT, were caused by serotype M18 strains that were genetically identical, or nearly so. Our analysis provides a critical foundation for accelerated research into ARF pathogenesis and a molecular framework to study the plasticity of GAS genomes.

AN - 85375589; pmid-12056690 AB - The prefrontal cortex is known to be involved in performing complex cognitive tasks requiring reasoning, planning and decision-making. Neuropsychological evidence also supports the idea that the prefrontal cortex is generally involved in encoding and retrieving complex events, such as action and narrative knowledge. Patients with frontal lobe damage are reported to have difficulty in processing different aspects of narrative representations, such as the figurative moral meaning, syntactic features, and inference generation. In the present study, we examined story processing in 17 patients with frontal lobe lesions and compared their performance to 7 amnesic patients and 17 normal controls. Two stories were presented by using two slightly different processing demands in order to assess the subject's ability to draw inferences on-line during the course of comprehension or later retrieval. Although all patients had impaired story memory, patients with frontal lobe lesions showed a pattern of deficit at an early stage of story comprehension that specifically involved the ability to reconstruct the sequential links among events and to extract inferential knowledge from the text during encoding. Amnesic patients were severely impaired in recalling story semantic units, including single events and larger narrative constituents, as well as in the event recognition task. Consequently, they were unable to establish inferential relations among the events and, thus, the global sequential structure of the stories during retrieval. In contrast, they had no difficulty in extracting inferential knowledge during story comprehension on the basis of readily available information. This study shows that damage to different cortical regions may induce impairments at various levels of story processing.

AN - 85366937; pmid-11934521 AB - The precise features of auditory perception in patients with auditory neuropathy have not been well described. In the present study, we examined auditory perception in a patient with auditory neuropathy. The patient was a right-handed 7-year-old boy. His chief complaint was delayed speech and suspected of verbal learning disability. He could talk, read and repeat rather fluently but could not understand fully what was asked. V-IQ, P-IQ and F-IQ of Wechsler Scale for Children III-R were 53, 118 and 81, respectively. Pure tone audiogram was completely normal. His speech discrimination ability was very poor. He could identify environmental sounds with visual matching. He could differentiate intensity difference but not time difference. This phenomenon was reported in patients with hemispheric symptoms. These clinical features are very similar to verbal auditory agnosia. ABR showed no response at 90dBnHL alternating clicks and tone bursts. Click evoked and distortion product otoacoustic emissions (OAE) were normal. Electrocochleogram was also normal. Motor and sensory nerve conduction velocity was completely normal. Pa of MLR and N1 of SVR were present. His diagnosis should be "pure type" of auditory neuropathy or auditory nerve disease. Importance of both ABR and OAE examination should be widely announced and auditory neuropathy must be campaigned stressed to be clinical entity among personnel who take care of children with speech delay.

In addition, the evolutionary forces behind the functional divergence of duplicated genes are often unknown, leading to disagreement on the relative importance of positive Darwinian selection versus relaxation of functional constraints in this process. The methodology of earlier studies relied largely on DNA sequence analysis but lacked functional assays of duplicated genes, frequently generating contentious results. Here we use both computational and experimental approaches to address these questions in a study of the pancreatic ribonuclease gene (RNASE1) and its duplicate gene (RNASE1B) in a leaf-eating colobine monkey, douc langur. We show that RNASE1B has evolved rapidly under positive selection for enhanced ribonucleolytic activity in an altered microenvironment, a response to increased demands for the enzyme for digesting bacterial RNA. At the same time, the ability to degrade double-stranded RNA, a non-digestive activity characteristic of primate RNASE1, has been lost in RNASE1B, indicating functional specialization and relaxation of purifying selection. Our findings demonstrate the contribution of gene duplication to organismal adaptation and show the power of combining sequence analysis and functional assays in delineating the molecular basis of adaptive evolution.

AN - 71988925; 12169201 AB - The step-wise accumulation of genetic and epigenetic alterations in cancer development includes chromosome rearrangements and viral integration-mediated genetic alterations that frequently involve proto-oncogenes. Proto-oncogenes deregulation lead to unlimited, self-sufficient cell growth and ultimately generates invasive and destructive tumors. C-MYC gene, the cellular homologue of the avian myelocitic leukemia virus, is implicated in a large number of human solid tumors, leukemias and lymphomas as well as in a variety of animal neoplasias. Deregulated MYC expression is a common denominator in cancer. Chromosomal rearrangements and integration of oncogenic viruses frequently target MYC locus, causing structural or functional alterations of the gene. In this article, we illustrate how genomic rearrangements and viruses integration affect MYC locus in certain human lymphomas and solid tumors.

AN - 71911207; 12118862 AB - A regimen combining sirolimus, tacrolimus, and daclizumab has recently been shown to provide adequate immunosuppression for allogeneic islet transplantation in humans, but remains unproven for primarily vascularized allografts. We evaluated this regimen for renal allograft transplantation in mismatched nonhuman primates. Dosages of sirolimus and tacrolimus were adjusted for trough levels of 10-15 ng/mL and 4-6 ng/mL, respectively. Treated monkeys (n = 5) had significantly prolonged allograft survival, with a mean survival of 36 days vs. 7 days in untreated controls (n = 6, p = 0.008). Four of five treated animals, but none of the controls, developed fibrinoid vascular necrosis of the small intestine. A review of gut histology from animals on other immunosuppressive protocols performed by our laboratory suggested that these lesions were a result of sirolimus exposure.

AN - 71890442; 12117070 AB - "Drug abuse" provides many unique challenges to the research community. Some of these involve fundamental epidemiologic issues, such as measuring the extent of the problem, identifying and assessing changes in patterns and trends, detecting emerging "drugs of abuse", characterizing vulnerable populations and determining health and social consequences. A number of research methods are employed to address these issues. This paper describes one of these--a model in which ongoing surveillance of "drug abuse" is maintained through a network of community-based researchers, local officials, academics, and other interested and qualified members of the community. Timely, accurate, and cost-effective data can be generated through systematic collection and analysis of indirect indicators of "drug abuse" that are often routinely produced by a variety of community sources. This information, in turn, can be used to make informed public health policy decisions. The community-based network model has been implemented at the city, state, national, regional, and international levels, and a case is made that this type of program could be useful, as well, in understanding the dynamics of "drug abuse" in rural areas of the country.

The single-dose plasma pharmacokinetics of O(2)-vinyl 1-(pyrrolidin-1-yl)diazen-1-ium-1,2-diolate (V-PYRRO/NO) following intravenous (i.v.) and intraperitoneal (i.p.) bolus administration to the male C57BL/6 mouse was studied in an effort to characterize the disposition of the agent and to serve as a basis for the design of in vivo efficacy studies. 2. Plasma V-PYRRO/NO concentrations declined rapidly in a bi-exponential manner after i.v. administration of 5 mg kg(-1) body weight to mouse. The terminal half-life was 9.4 min and the mean residence time was 3.4 min. 3. V-PYRRO/NO was absorbed rapidly following i.p. administration, with peak plasma concentrations being observed 3 min after injection. Levels then declined with a terminal half-life of 11.7 min. The bioavailable fraction from the i.p. compartment was 19%, indicating a high first-pass effect. 4. The results provide additional evidence for a liver-selective metabolism of this nitric oxide-donating prodrug.

AN - 71714273; 12024108 AB - Histidine-rich glycoprotein (HRG) binds heparin and neutralizes its anticoagulant effect. Because zinc greatly enhances this interaction, it is possible that the combination of HRG and zinc could be used as an antidote for heparin. We have determined the plasma concentrations of HRG and zinc necessary to neutralize clinically relevant concentrations of heparin. Using a thrombin-time assay, we found that HRG plus zinc can neutralize 0.2 to 4.5 units/mL heparin, although the maximal effect requires an HRG plasma concentration about six times normal and a zinc concentration about 10 times normal. In a system using purified proteins and a thrombin-specific chromogenic substrate, we found that both the concentration of HRG and the molar ratio of HRG to zinc are important in determining the potency of the anti-heparin activity. Whether HRG and zinc can be administered as an antidote for heparin will depend on whether the requisite doses can be achieved without toxicity.

National Institutes of Health. Recent, basic, clinical, and epidemiological studies. None. Effects of androgens on mammary epithelial proliferation and/or breast cancer incidence. Experimental data derived from rodents and cell lines provide conflicting results that appear be strain- and cell line-dependent. Epidemiologic studies have significant methodological limitations and provide inconclusive results. The study of molecular defects involving androgenic pathways in breast cancer is in its infancy. Clinical and nonhuman primate studies, however, suggest that androgens inhibit mammary epithelial proliferation and breast growth and that conventional estrogen treatment suppresses endogenous androgens. Abundant clinical evidence suggests that androgens normally inhibit mammary epithelial proliferation and breast growth. Suppression of androgens by conventional estrogen treatment may thus enhance estrogenic breast stimulation and possibly breast cancer risk. Clinical trials to evaluate the impact of combined estrogen and androgen hormone replacement regimens on mammary gland homeostasis are needed to address this issue.

AN - 71656449; 11993471 AB - Copper has been suggested to facilitate oxidative tissue injury through a free radical-mediated pathway analogous to the Fenton reaction. By applying the electron spin resonance (ESR) spin-trapping technique, evidence for hydroxyl radical formation in vivo was obtained in rats treated simultaneously with copper and ascorbic acid or paraquat. A secondary radical spin-trapping technique was used in which the hydroxyl radical formed the methyl radical upon reaction with dimethylsulfoxide. The methyl radical was then detected by ESR spectroscopy as its adduct with the spin trap phenyl-N-t-butyl- nitrone (PBN). In contrast, lipid derived radical was detected in vivo in copper-challenged, vitamin E and selenium-deficient rats. These findings support the proposal that dietary selenium and vitamin E can protect against lipid peroxidation and copper toxicity. Since copper excreted into the bile from treated animals is expected to be maintained in the Cu(I) state (by ascorbic acid or glutathione), a chelating agent that would redox-stablilize it in the Cu(I) state was used to prevent ex vivo redox chemistry. Bile samples were collected directly into solutions of bathocuproinedisulfonic acid, a Cu(I)-stabilizing agent, and 2,2'-dipyridyl, a Fe(II)-stabilizing agent. If these precautions were not taken, radical adducts generated ex vivo could be mistaken for radical adducts produced in vivo and excreted into the bile. JF - Spectrochimica acta.

AN - 71647467; 11986596 AB - Although paclitaxel is widely used as a systemic agent for the treatment of solid tumors, limited information is available concerning administration of this taxane by regional techniques. The present study was undertaken to evaluate the pharmacokinetics and acute toxicity of paclitaxel administered by hyperthermic retrograde isolated lung perfusion techniques to ascertain its potential for the regional therapy of unresectable pulmonary neoplasms. Adult sheep underwent 90 minutes of retrograde isolated lung perfusion with escalating doses of paclitaxel and moderate hyperthermia using a protein-free, oxygenated extracorporeal circuit and a steady perfusion pressure of 14 to 16 mm Hg. An additional animal received paclitaxel by means of 1-hour central venous infusion. Paclitaxel concentrations in lung tissues, perfusates, and systemic circulation were determined by high-performance liquid chromotography techniques. Cytotoxicity of paclitaxel in cancer cells and in normal human bronchial epithelial cells was evaluated in vitro using 4, 5-dimethylthiazo-2-yl-25-dipagnyl tetrazolium bromide assays. Lung tissues were examined by hematoxylin-and-eosin techniques. Paclitaxel concentrations (maximum concentration and area under the plasma concentration time curve) in perfused tissues increased with escalating perfusate doses. Uptake of drug into lung parenchyma appeared saturable at high paclitaxel exposure; a substantial pharmacokinetic advantage was observed. Paclitaxel concentrations in systemic circulation were undetectable or exceedingly low after perfusion. Histopathologic examination of lung tissues harvested 3 hours after completion of isolated lung perfusion revealed no immediate toxicity, even at a paclitaxel exposure 20-fold higher than that achievable after 1 hour of intravenous administration at the maximum tolerable dose in human subjects. Moderate hyperthermia enhanced paclitaxel-mediated cytotoxicity 5- to 100-fold in cultured cancer lines. No paclitaxel toxicity was observed in cultured normal human bronchial epithelial cells after exposure to paclitaxel under normothermic or hyperthermic conditions.

AN - 71640975; 11983166 AB - The mechanism involved in [Ca(2+)](i)-dependent feedback inhibition of store-operated Ca(2+) entry (SOCE) is not yet known. Expression of Ca(2+)-insensitive calmodulin (Mut-CaM) but not wild-type CaM increased SOCE and decreased its Ca(2+)-dependent inactivation. Expression of TrpC1 lacking C terminus aa 664-793 (TrpC1DeltaC) also attenuated Ca(2+)-dependent inactivation of SOCE. CaM interacted with endogenous and expressed TrpC1 and with GST-TrpC1 C terminus but not with TrpC1DeltaC. Two CaM binding domains, aa 715-749 and aa 758-793, were identified. Expression of TrpC1Delta758-793 but not TrpC1Delta715-749 mimicked the effects of TrpC1DeltaC and Mut-CaM on SOCE. These data demonstrate that CaM mediates Ca(2+)-dependent feedback inhibition of SOCE via binding to a domain in the C terminus of TrpC1. These findings reveal an integral role for TrpC1 in the regulation of SOCE.

AN - 71610156; 11964058 AB - Given our close phylogenetic relatedness, non-human primates, in principle, could serve as an ideal model for alcoholism. Indeed, many studies in both humans and rhesus macaques show relationships between excessive alcohol consumption, aggression and serotonergic function, as measured by concentrations of the principal metabolite of serotonin, 5-hydroxyindoleacetic acid (5-HIAA) in the cerebrospinal fluid (CSF). An important behavioral predictor of excessive alcohol consumption in both humans and rhesus monkeys is the propensity toward impulsivity. Integrating behavioral and neuroendocrine data from captive and semi-free-ranging rhesus macaques, we posit that benefits derived from impulsive and aggressive behaviors in some contexts might contribute indirectly to the maintenance of traits involved in alcoholism and excessive alcohol intake.

AN - 71602249; 11951211 AB - Progressive growth of unresectable metastatic or primary malignancies confined to the liver is a significant clinical problem. Approximately 25% of patients with colorectal cancer will develop metastatic disease exclusively or largely confined to liver, the vast majority of which are not amenable to surgical resection. Despite aggressive systemic or regional chemotherapy, survival is only 12 to 18 months. More than 80% of patients with ocular melanoma develop liver metastases as the first site of recurrent disease, and death from hepatic disease progression typically occurs 2 to 7 months after diagnosis. In addition, the liver is also the preferred site of metastatic disease for gastrointestinal or pancreatic neuroendocrine tumors. A number of physiological and anatomic features of the liver make it an ideal organ for regionally directed therapy to allow dose intensification to the cancer-burdened area while reducing or eliminating unnecessary systemic toxicity. To that end, complete vascular isolation and perfusion of the liver using a recirculating extracorporeal circuit, also called isolated hepatic perfusion (IHP), has been under clinical evaluation at our institution and others. In this article, we review the current results with IHP and its potential utility in the treatment of patients with unresectable hepatic malignancies.

AN - 71595394; 11940462 AB - At the request of the U.S. Environmental Protection Agency (U.S. EPA), the National Toxicology Program organized an independent and open peer review to evaluate the scientific evidence on low-dose effects and nonmonotonic dose-response relationships for endocrine-disrupting chemicals in mammalian species. For this peer review, "low-dose effects" referred to biologic changes that occur in the range of human exposures or at doses lower than those typically used in the standard testing paradigm of the U.S. EPA for evaluating reproductive and developmental toxicity. The demonstration that an effect is adverse was not required because in many cases the long-term health consequences of altered endocrine function during development have not been fully characterized. A unique aspect of this peer review was the willing submission of individual animal data by principal investigators of primary research groups active in this field and the independent statistical reanalyses of selected parameters prior to the peer review meeting by a subpanel of statisticians. The expert peer-review panel (the panel) also considered mechanistic data that might influence the plausibility of low-dose effects and identified study design issues or other biologic factors that might account for differences in reported outcomes among studies. The panel found that low-dose effects, as defined for this review, have been demonstrated in laboratory animals exposed to certain endocrine-active agents. In some cases where low-dose effects have been reported, the findings have not been replicated. The shape of the dose-response curves for reported effects varied with the end point and dosing regimen and were low-dose linear, threshold-appearing, or nonmonotonic. The findings of the panel indicate that the current testing paradigm used for assessments of reproductive and developmental toxicity should be revisited to see whether changes are needed regarding dose selection, animal-model selection, age when animals are evaluated, and the end points being measured following exposure to endocrine-active agents.

AN - 71590771; 11948105 AB - Recombinant immunotoxins are fusion proteins composed of the Fv domains of antibodies fused to bacterial or plant toxins that are being developed for the targeted therapy of cancer. RFB4 (Fv)-Pseudomonas exotoxin 38 (PE38) is an immunotoxin that targets CD22 expressed on B cells and B-cell malignancies. A disulfide-stabilized form of RFB4 (Fv)-PE38 is being evaluated in a Phase I clinical trial. The aim of the present study was to improve the activity of RFB4 (Fv)-PE38 to more effectively treat patients with leukemias and lymphomas. To increase the affinity of RFB4 (Fv), we used the techniques of phage display and hot spot mutagenesis. We identified mutational hot spot sequences in heavy chain complementary determining region 3 (V(H) CDR3) and randomized these in a phage display library. Mutant phages were panned on CD22-positive Daudi cells. A variety of mutant Fvs were obtained, and the corresponding immunotoxins were prepared. Several mutant immunotoxins with increased binding affinity and cytotoxic activity were obtained. The most active immunotoxin contained amino acid residues Thr-His-Trp (THW) in place of Ser-Ser-Tyr (SSY) at positions 100, 100A, and 100B of the Fv and had an affinity improved from 85 nM to 6 nM.

AN - 71589623; 11940448 AB - Lead is classified as a possible carcinogen in humans. We studied the relationship of blood lead level and all cancer mortality in the general population of the United States using data from the National Health and Nutrition Examination Survey II (NHANES II) Mortality Study, 1992, consisting of a total of 203 cancer deaths (117 men and 86 women) among 3,592 whites (1,702 men and 1,890 women) with average of 13.3 years of follow-up. We used Cox proportional hazard regression models to estimate the dose-response relationship between blood lead and all cancer mortality. Log-transformed blood lead was either categorized into quartiles or treated as a continuous variable in a cubic regression spline. Relative risks (RRs) were estimated for site-specific cancers by categorizing lead above and below the median. Among men and women combined, dose-response relationship between quartile of blood lead and all cancer mortality was not significant (ptrend = 0.16), with RRs of 1.24 [95% percent confidence interval (CI), 0.66-2.33], 1.33 (95% CI, 0.57-3.09), and 1.50 (95% CI, 0.75-3.01) for the second, third, and fourth quartiles, respectively, compared with the first quartile. Spline analyses found no dose response (p = 0.29), and none of the site-specific cancer RRs were significant. Among men, no significant dose-response relationships were found for quartile or spline analyses (p trend = 0.57 and p = 0.38, respectively). Among women, no dose-response relationship was found for quartile analysis (ptrend = 0.22). However, the spline dose-response results were significant (p = 0.001), showing a threshold effect at the 94th percentile of blood lead or a lead concentration of 24 microg/dL, with an RR of 2.4 (95% CI, 1.1-5.2) compared with the risk at 12.5 percentile. Because the dose-response relationship found in women was not found in men, occurred at only the highest levels of lead, and has no clear biologic explanation, further replication of this relationship is needed before it can be considered believable. In conclusion, individuals with blood lead levels in the range of NHANES II do not appear to have increased risk of cancer mortality.

AN - 71587449; 11953977 AB - Immunosuppressive agents have become the standard of therapy for proliferative lupus nephritis, but some patients may relapse after discontinuing treatment. We reviewed the cases of renal flares in a cohort of patients who participated in 2 randomized controlled clinical trials at the National Institutes of Health and explored the prevalence, outcome, and predictive factors of renal flares. Data were obtained on 145 patients treated with pulse cyclophosphamide, pulse methylprednisolone, or the combination of both. Patients had not received immunosuppressive therapy for at least 6 months and had experienced complete or partial response according to defined criteria. Renal flares were classified as either proteinuric or nephritic based on changes in urinary protein and sediment. Most patients who experienced a flare received additional immunosuppressive therapy. Seventy-three patients had a complete response, and 19 had partial response/stabilization. Forty-one of these patients (45%) experienced renal flares (nephritic in 33, proteinuric in 8) after a mean followup of 117 months; 31 of them received additional immunosuppressive therapy. The median time to renal flare was 36 months in the complete responders and 18 months in the partial responders. Eleven of the 41 patients (27%) progressed to end-stage renal disease (ESRD); 9 had nephritic flares (all severe except for 1) and 2 had proteinuric flares (1 in each responder group). Compared with patients who had a complete response, those with a partial response were more likely to experience a flare, to have a severe nephritic flare, or to progress to ESRD. Low C4 at the time of response and African American ethnicity were significant independent risk factors for renal flare, by multivariate Cox proportional hazards analysis. Nephritic flares are common in patients with proliferative lupus nephritis, even in those with a complete response to therapy, but they do not necessarily result in loss of renal function if treated with additional immunosuppressive agents. Renal flares are an important feature of the natural history of lupus nephritis and provide an opportunity for additional preventive strategies, as well as measures of efficacy in future therapeutic trials.

AN - 71581454; 11940459 AB - Population-based estimates of environmental exposures using biomarkers can be difficult to obtain for a variety of reasons, including problems with limits of detection, undersampling of key strata, time between exposure and sampling, variation across individuals, variation within individuals, and the ability to find and interpret a given biomarker. In this article, we apply statistical likelihoods, weighted sampling, and regression methods for censored data to the analysis of biomarker data. Urinary metabolites for seven phthalates, reported by Blount et al., are analyzed using these methods. In the case of the phthalates data, we assumed the underlying model to be a log-normal distribution with the mean of the distribution defined as a function of a number of demographic variables that might affect phthalate levels in individuals. Included as demographic variables were age, sex, ethnicity, residency, family income, and education level. We conducted two analyses: an unweighted analysis where phthalate distributions were estimated with changes in the means of these distributions as a function of demographic variables, and a weighted prediction for the general population in which weights were assigned for a subset of the population depending on the frequency of their demographic variables in the general U.S. population. We used statistical tests to determine whether any of the demographic variables affected mean phthalate levels. Individuals with only a high school education had higher levels of di-n-butyl phthalate than individuals with education beyond high school. Subjects who had family income less than $1,500 in the month before sampling and/or only high school education had higher levels of n-butyl benzyl phthalate levels than other groupings. Di(2-ethylhexyl) phthalate was higher in males and/or in urban populations and/or in people who had family income less than $1,500 per month. Our findings suggest that there may be significant demographic variations in exposure and/or metabolism of phthalates and that health-risk assessments for phthalate exposure in humans should consider different potential risk groups.

AN - 71579587; 11938511 AB - Wear of orthopaedic implants generates particles capable of inducing bone resorption and aseptic loosening of the implant. The present study shows the combined effect of particles and cell activation on macrophage (THP-1) and osteoclast (HD-11EM) release of reactive oxygen and nitrogen species, providing insight into mechanisms that can lead to osteolysis. In the absence of cell activation, exposure of either cell type to submicron zirconia or latex particles did not elicit an increase in reactive oxygen and nitrogen species production. Suboptimal stimulation with 4 beta-phorbol-12-myristate-13-acetate (PMA) plus particles resulted in a synergistic release of superoxide (O2-), however, and a low-level production of nitric oxide small middle dot by THP-1 macrophages. Similarly, particle stimulation of tumor necrosis factor-alpha-activated THP-1 cells increased O2- release. Our findings show the synergistic effect of cell activation and wear particles on O2- production by activated macrophages and osteoclasts, suggesting O2- involvement in mediating osteolysis.

AN - 71574425; 11923448 AB - Rats with neonatal excitotoxic damage of the ventral hippocampus display in adulthood a variety of abnormalities reminiscent of schizophrenia and are used as an animal model of this disorder. In the present study, we hypothesized that transient inactivation of ventral hippocampal activity during a critical developmental period may be sufficient to disrupt normal maturation of relevant brain systems and produce similar lasting behavioral changes. We infused tetrodotoxin (TTX) or artificial CSF into the ventral hippocampus on postnatal day 7 (P7) and assessed behavioral changes in response to stress, amphetamine, and (+)-5-methyl-10,11-dihydro-5H-dibenzo [a,d] cyclohepten-5,10-imine maleate in juvenile (P35) and young adult (P56) rats. In adulthood, rats infused neonatally with TTX displayed motor hyperactivity after pharmacological stimulation and after stress compared with sham controls. Analogous TTX infusions in adult animals did not alter these behaviors later in life. These data suggest that transient loss of ventral hippocampal function during a critical time in maturation of intracortical connections permanently changes the development of neural circuits mediating certain dopamine- and NMDA-related behaviors. These results represent a potential new model of aspects of schizophrenia without involving a gross anatomic lesion.

AN - 71571809; 11921335 AB - Development and differentiation of the mammary gland occurs by means of critical stromal-epithelial interactions. Although many studies have attempted to understand these complex interactions, it has been difficult to demonstrate the essential role of adipose tissue in the development and function of the mammary gland. By using the A-ZIP/F-1 transgenic mice lacking in white adipose tissue (WAT), we have studied the role of adipocytes in mammary gland development and differentiation. In the absence of WAT, rudimentary mammary anlagen form but are unable to grow and branch normally, resulting in a few, short, severely distended ducts. However, during pregnancy, a tremendous amount of epithelial cell division and alveolar cell formation occurs even in the absence of adipocytes, illustrating that adipose tissue is not required for mammary gland differentiation. Mammary gland transplantation revealed that epithelial cells from these transgenic mice possess the potential for normal growth and differentiation when placed into a normal stromal environment. These experiments clearly demonstrate that the absence of adipocytes in the mammary gland results in disruption of stromal-epithelial interactions that prevent normal mammary gland development. The rudimentary epithelial anlage, however, contain mammary stem cells, which are fully capable of alveolar differentiation. Published 2002 Wiley-Liss, Inc.

AN - 71571195; 11929728 AB - The recent growth and restructuring of the swine industry in the state of Mississippi has raised various environmental and socioeconomic concerns. We spatially examined the location and attributes of 67 industrial hog operations to determine if African American and low-income communities have a high prevalence of industrial hog operations located near their neighborhoods at the census block group level. We used spatial data and cross-classification analysis to compare the prevalence of industrial hog operations in neighborhoods that are primarily African American and low income with the prevalence in neighborhoods that are African American and affluent. We also used logistic regression to evaluate the relationship between the environmental justice variables and the location of the industrial hog operations. The block group characterization showed a high prevalence of hog operations in the four highest quintiles compared with the lowest quintile for percentage African American and percentage poverty. At increasing levels of percentage African Americans and percentage of persons in poverty, there are 2.4-3.6 times more operations compared with the referent group; additionally, scale adjustment to only the hog counties reduces this to 1.8-3.1 more operations compared with the referent group. The inequitable distribution of hog-confined agricultural feeding operations in these communities may have adverse environmental impacts associated with industrial hog production, such as increased health risks and quality of life degradation, as have occurred in other areas having similar facilities.

AN - 71561251; 11925476 AB - Garlic is appealing as an anti-carcinogenic agent due to its ability to induce apoptosis in vitro and inhibit the formation and growth of tumors in animals in vivo. Diallyl disulfide (DADS) is a constituent of garlic that suppresses neoplastic cell growth and induces apoptosis. We examined the effects of DADS on various cancer cell lines to better understand its effect on apoptosis and apoptosis-related genes. The nonsteroidal anti-inflammatory drug (NSAID)-activated gene (NAG-1) has proapoptotic and antitumorigenic activities and is upregulated by anticancer agents such as NSAIDs. In this study, human colorectal HCT-116 (wild-type p53), HCT-15 (p53 mutant) and human prostate PC-3 (p53 mutant) cells were exposed to DADS. DADS inhibited cell proliferation in all cell lines albeit to a lesser extent in HCT-15 and PC-3 cells at 11.5 and 23 micromol/L. In HCT-116 cells, DADS induced p53 and NAG-1 in a dose-dependent manner and the induction of p53 preceded that of NAG-1. In HCT-116 cells, NAG-1 protein expression was increased 2.4-fold +/- 0.6 at 4.6 micromol/L and 6.1-fold +/- 1.7 at 23 micromol/L DADS, whereas p53 was induced 1.5-fold +/- 0.1 and 2.3-fold +/- 0.4. DADS did not induce NAG-1 or p53 in p53 mutant cell lines; however, NAG-1 expression was induced by sulindac sulfide. HCT-116 cells treated with 4.6 and 23 micromol/L DADS resulted in a 1.9- and 2.9-fold increase in apoptosis, respectively. In contrast, 23 micromol/L DADS induced apoptosis only 1.8-fold in HCT-15 cells and not at all in PC-3 cells. Thus, DADS-induced apoptosis and NAG-1 protein expression appear to occur via p53.

AN - 71556109; 11917235 AB - Antiretroviral nucleoside analogue drugs are a major constituent of highly active antiretroviral therapy (HAART), the most advanced form of treatment for HIV-1 infection. Currently, HAART combinations that include zidovudine (ZDV) and lamivudine (3TC) are highly effective in preventing HIV-1 vertical transmission; most children are born with no evident adverse clinical effects. However, ZDV is a moderately strong transplacental carcinogen in mice, and potential long-term consequences of fetal exposure to most HAART combinations remain unknown. To model human transplacental ZDV and 3TC exposures, experiments were performed in Erythrocebus patas monkeys given human-equivalent drug exposure protocols. Pregnant monkeys were dosed with either no drug (n = 2), 40.0 mg ZDV/d (about 6 mg/kg body weight/d) for the last 50% (10 weeks) of gestation (n = 3), or with the same regimen of ZDV plus 24.0 mg 3TC/d (about 3.6 mg/kg body weight/d) for the last 20% (4 weeks) of gestation (n = 3). Multiple fetal organs were examined at term for DNA incorporation of ZDV and 3TC using two separate radioimmunoassays (RIAs). Values for ZDV-DNA incorporation were similar in fetuses exposed to ZDV alone and those exposed to ZDV plus 3TC. Values for 3TC-DNA in fetal organs were greater than or equal to values for ZDV-DNA, indicating that the total DNA damage sustained by fetuses exposed to both drugs was at least double that observed in fetuses exposed to ZDV alone. Telomere shortening, determined by Southern blot with a telomeric probe, was observed in most organs of the three animals exposed in utero to ZDV plus 3TC. No telomere shortening was evident in the unexposed fetuses, and occasional telomere shortening was found in fetuses exposed to ZDV alone. Overall, these studies demonstrate that monkey fetuses exposed in utero to the combination ZDV plus 3TC sustain a higher level of drug-DNA incorporation and show evidence of more telomere damage than monkey fetuses exposed to ZDV alone.

AN - 71551196; 11919229 AB - To evaluate the value of thymidylate synthase (TS), Ki-67, and p53 as prognostic markers in patients with Dukes' B2 and C colon carcinoma. We conducted a retrospective analysis to evaluate the prognostic value of TS, Ki-67, and p53 in 465 patients with Dukes' B2 (220 patients) or Dukes' C (245 patients) colon carcinoma. Patients represent a nonrandom subset obtained from five randomized phase III trials and were treated with either surgery alone (151 patients) or surgery plus fluorouracil-based chemotherapy (314 patients). All three markers were assayed using immunohistochemical techniques. With a minimum follow-up of 5 years, our retrospective analysis failed to demonstrate a consistent and significant association between TS, Ki-67, or p53 and either disease-free survival or overall survival. Exploratory analyses did not reveal a convincing explanation for these results that are in conflict with the published literature. Notable interactions were observed. In particular, high Ki-67 levels were associated with increased (decreased) survival in patients with low (high) TS intensity. Patients whose tumors stained positively for p53 seemed to benefit substantially from the use of adjuvant chemotherapy compared with those who were not treated (P =.05). This retrospective investigation failed to demonstrate a significant association between TS, Ki-67, or p53 staining and clinical outcome.

AN - 71550837; 11919233 AB - Oxaliplatin is a novel platinum compound with clinical activity in several malignancies. Neurotoxicity is dose-limiting and occurs in two distinct forms, an acute neurologic symptom complex that occurs within hours or days of therapy and a chronic, cumulative sensory neuropathy. Patients were treated in a phase I study designed to establish the maximum-tolerated dose of capecitabine given with oxaliplatin. Because of the unusual neurosensory toxicity of oxaliplatin, detailed neurologic examination, needle electromyography (EMG), and nerve conduction studies (NCS) were performed before and the day after oxaliplatin in a subset of 13 patients. Carbamazepine therapy was tried in 12 additional patients to determine whether the neurologic effects might be relieved. All patients experienced acute, reversible neurotoxicities with oxaliplatin. Symptoms included paresthesias, dysesthesias, cold hypersensitivity, jaw pain, eye pain, pain in the arm used for drug infusion, ptosis, leg cramps, and visual and voice changes. Serial EMG and NCS revealed striking signs of hyperexcitability in motor nerves after oxaliplatin. In patients who achieved therapeutic levels, carbamazepine did not alter the clinical or electromyographic abnormalities. The acute neurotoxicity seen with oxaliplatin is characterized by peripheral-nerve hyperexcitability, and the findings are similar to the clinical manifestations of neuromyotonia. Carbamezepine, which provides symptomatic relief in acquired neuromytonia, did not seem to be beneficial.

AN - 71544001; 11901228 AB - Cocaine's blockade of dopamine reuptake by brain dopamine transporters (DAT) is a central feature of current understanding of cocaine reward and addiction. Empirical screening of small-molecule chemical libraries has thus far failed to provide successful cocaine blockers that allow dopamine reuptake in the presence of cocaine and provide cocaine "antagonism". We have approached this problem by assessing expression, dopamine uptake, and cocaine analog affinities of 56 DAT mutants in residues located in or near transmembrane domains likely to play significant roles in cocaine recognition and dopamine uptake. A phenylalanine-to-alanine mutant in putative DAT transmembrane domain 3, F154A, retains normal dopamine uptake, lowers cocaine affinity 10-fold, and reduces cocaine stereospecificity. Such mutants provide windows into DAT structures that could serve as targets for selective cocaine blockers and document how combined strategies of mutagenesis and small molecule screening may improve our abilities to identify and design compounds with such selective properties.

AN - 71539576; 11895980 AB - A major obstacle to studying the functions of particular gene products in the mouse-tick infectious cycle of Borrelia burgdorferi has been an inability to knock out genes in pathogenic strains. Here, we investigated conditions for site-directed mutagenesis in B31 MI, the low-passage-number, infectious B. burgdorferi strain whose genome was sequenced. We inactivated several plasmid and chromosomal genes in B31 MI and determined that clones carrying these mutations were not infectious for mice. However, we found extensive heterogeneity among clones and mutants derived from B31 MI based on colony phenotype, growth rate, plasmid content, protein profile, and transformability. Significantly, several B31 MI clones that were not subjected to mutagenesis but that lacked particular plasmids also exhibited defects at various stages in the infectious cycle. Therefore, the high degree of clonal polymorphism within B31 MI complicates the assessment of the contributions of individual genes to the observed phenotypes of the mutants. Our results indicate that B31 MI is not an appropriate strain background for genetic studies in infectious B. burgdorferi, and a well-defined isogenic clone is a prerequisite for targeted mutagenesis. To this end, we derived several wild-type clones from B31 MI that were infectious for mice, and gene inactivation was successful in one of these clones. Due to the instability of the genome with in vitro propagation, careful monitoring of plasmid content of derived mutants and complementation of inactivated genes will be crucial components of genetic studies with this pathogen.

AN - 71538966; 11909700 AB - Mice that harbored the x-ray-induced low efficiency allele of the major X-linked isozyme of glucose-6-phospate dehydrogenase (G6PD), Gpdx(a-m2Neu), and, in addition, harbored the transgenic shuttle vector for the determination of mutagenesis in vivo, pUR288, were employed to further our understanding of the interdependence of general metabolism, oxidative stress control, and somatic mutagenesis. The Gpdx(a-m2Neu) mutation conferred moderate G6PD deficiency in hemizygous males (Gpdx(a-m2Neu/y)) displaying residual enzyme activities of 27% in red blood cells and 13% in brain (compared to wild-type controls, Gpdx(a/y) males). In spite of this mild phenotype, the brains of G6PD-deficient males exhibited a significant distortion of redox control ( approximately 3-fold decrease in the ratio of reduced glutathione to oxidized glutathione), a considerable accumulation of promutagenic etheno DNA adducts ( approximately 13-fold increase in ethenodeoxyadenosine and approximately 5-fold increase in ethenodeoxycytidine), and a substantial elevation of somatic mutation rates ( approximately 3-fold increase in mutant frequencies in lacZ, the target and reporter gene of mutagenesis in the shuttle vector, pUR288). The mutation pattern in the brain was dominated by illegitimate genetic recombinations, a presumed hallmark of oxidative mutagenesis. These findings suggested a critical function for G6PD in limiting oxidative mutagenesis in the mouse brain.

AN - 71538719; 11910270 AB - A role for serotonin in season affective disorder (SAD) has been explored with a variety of serotonergic pharmacologic agents. The authors initially hypothesized that metergoline, a nonspecific serotonin antagonist, would exacerbate depressive symptoms. In a small, open-label pilot study, the authors observed the opposite effect. They decided to follow up on this finding with this formal study. The study followed a double-blind, randomized cross-over design. Sixteen untreated, depressed patients with SAD received single oral doses of metergoline 8 mg and of placebo, spaced 1 week apart. Fourteen patients were restudied after 2 weeks of light treatment. Depression ratings using the Structured Interview Guide for the Hamilton Depression Rating Scale-Seasonal Affective Disorder Version were performed at baseline and at 3 and 6 days after each intervention. These data were analyzed by baseline-corrected repeated measures with analysis of variance. In the off-lights condition, severity of depression was diminished after metergoline compared with placebo administration (p = 0.001). Patient daily self-ratings suggested that the peak effect occurred 2 to 4 days after study drug administration. In contrast, after 2 weeks of treatment with bright artificial light, metergoline did not demonstrate a significant effect on mood. These data suggest that single doses of metergoline may have antidepressant effects that last several days. Possible mechanisms include 5-hydroxytryptamine(2) receptor downregulation and dopamine agonism.

AN - 71533434; 11907109 AB - Kidney cancer is a devastating disease; however, biological therapies have achieved some limited success. The murine renal cancer Renca has been used as a model for developing new preclinical approaches to the treatment of renal cell carcinoma. Successful cytokine-based approaches require CD8(+) T cells, but the exact mechanisms by which T cells mediate therapeutic benefit have not been completely identified. After successful biological therapy of Renca in BALB/c mice, we generated CTLs in vitro using mixed lymphocyte tumor cultures. These CTL mediated tumor-specific H-2K(d)-restricted lysis and production of IFN-gamma, TNF-alpha, and Fas ligand (FasL) in response to Renca. CTL used both granule- and FasL-mediated mechanisms to lyse Renca, although granule-mediated killing was the predominant lytic mechanism in vitro. The cytokines IFN-gamma and TNF-alpha increased the sensitivity of Renca cells to CTL lysis by both granule- and FasL-mediated death pathways. Adoptive transfer of these anti-Renca CTL into tumor-bearing mice cured most mice of established experimental pulmonary metastases, and successfully treated mice were immune to tumor rechallenge. Interestingly, we were able to establish Renca-specific CTL from mice gene targeted for perforin (pfp(-/-)) mice. Although these pfp(-/-) CTL showed reduced cytotoxic activity against Renca, their IFN-gamma production in the presence of Renca targets was equivalent to that of wild-type CTL, and adoptive transfer of pfp(-/-) CTL was as efficient as wild-type CTL in causing regression of established Renca pulmonary metastases. Therefore, although granule-mediated killing is of paramount importance for CTL-mediated lysis in vitro, some major in vivo effector mechanisms clearly are independent of perforin.

AN - 71528471; 11895933 AB - Neisserial Opa proteins function as a family of adhesins that bind heparan sulfate proteoglycan (HSPG) or carcinoembryonic antigen family (CEACAM) receptors on human host cells. In order to define the CEACAM binding domain on Opa proteins, we tested the binding properties of a series of gonococcal (strain MS11) recombinants producing mutant and chimeric Opa proteins with alterations in one or more of the four surface-exposed loops. Mutagenesis demonstrated that the semivariable domain, present in the first loop, was completely dispensable for CEACAM binding. In contrast, the two hypervariable (HV) regions present in the second and third loops were essential for binding; deletion of either domain resulted in loss of receptor recognition. Deletion of the fourth loop resulted in a severe decrease in Opa expression at the cell surface and could therefore not be tested for CEACAM binding. Chimeric Opa variants, containing combinations of HV regions derived from different CEACAM binding Opa proteins, lost most of their receptor binding activity. Some chimeric variants gained HSPG binding activity. Together, our results indicate that full recognition of CEACAM receptors by Opa proteins requires a highly coordinate interplay between both HV regions. Furthermore, shuffling of HV regions may result in novel HSPG receptor binding activity.

AN - 71527173; 11901223 AB - CYP2J2 is abundant in cardiovascular tissue and active in the metabolism of arachidonic acid to eicosanoids that possess potent anti-inflammatory, vasodilatory, and fibrinolytic properties. We cloned and sequenced the entire CYP2J2 gene (approximately 40.3 kb), which contains nine exons and eight introns. We then sequenced the CYP2J2 exons and intron-exon boundaries in 72 healthy persons representing African, Asian, and European/white populations as part of the National Institutes of Health/National Institute of Environmental Health Sciences Environmental Genome Single Nucleotide Polymorphism Program. A variety of polymorphisms were found, four of which resulted in coding changes (Arg158Cys, Ile192Asn, Asp342Asn, and Asn404Tyr). A fifth variant (Thr143Ala) was identified by screening a human heart cDNA library. All five variant cDNAs of CYP2J2 were generated by site-directed mutagenesis and expressed in Sf9 insect cells by using a baculovirus system. The recombinant wild-type and variant CYP2J2 proteins immunoreacted with peptide-based antibodies to CYP2J2 and displayed typical cytochrome P450 (P450) CO-difference spectra; however, the Asn404Tyr and Ile192Asn variants also had prominent spectral peaks at 420 nm. The ability of these variants to metabolize arachidonic acid and linoleic acid was compared with that of wild-type CYP2J2. Three variants (Asn404Tyr, Arg158Cys, and Thr143Ala) showed significantly reduced metabolism of both arachidonic acid and linoleic acid. The Ile192Asn variant showed significantly reduced activity toward arachidonic acid only. The Asp342Asn variant showed similar metabolism to wild-type CYP2J2 for both endogenous substrates. Based on these data, we conclude that allelic variants of the human CYP2J2 gene exist and that some of these variants result in a P450 protein that has reduced catalytic function. Insofar as CYP2J2 products have effects in the cardiovascular system, we speculate that these variants may be functionally relevant.

AN - 71522010; 11896293 AB - The disposition and toxicity of inhaled elemental mercury (Hg0) vapor for pregnant Long-Evans rats, and potential adverse effects on reproductive outcome were investigated. Rats were exposed to 0, 1, 2, 4, or 8 mg Hg0/m(3) for 2 h/day from gestation day (GD) 6 through GD 15. Maternal toxicity occurred primarily in rats exposed to 4 and 8 mg/m(3) and was manifested as a concentration-related decrease in body weight gain and mild nephrotoxicity. Control rats gained about 13% of their initial body weight during the 10-day exposure. Rats exposed to 4 mg/m(3) Hg0 gained about 7% less than controls, and rats exposed to 8 mg/m(3) Hg0 lost about 17% of their initial body weight during the 10-day exposure period. Maternal kidney weights were significantly increased in the 4 and 8 mg/m(3) concentration groups, and urinalysis revealed increased levels of protein and alkaline phosphatase activity in urine of all Hg0-exposed rats. Dams exposed to 8 mg/m(3) were euthanized in moribund condition on postnatal day (PND) 1. There was no histopathological evidence of toxicity in maternal lung, liver, or kidney of exposed rats at GD 6, GD 15, or PND 1. The incidence of resorptions was significantly increased, litter size and PND 1 neonatal body weights were significantly decreased only in the 8-mg/m(3) group. Total Hg concentrations in maternal tissues increased with increasing number of exposure days and concentration. In general, approximately 70% of Hg was eliminated from maternal tissues during the week following the last exposure (GD 15 to PND 1). Elimination of Hg from maternal brain and kidney was slower than in other tissues, possibly due to higher levels of metallothionein. Total Hg concentrations in fetal tissues increased with increasing number of exposure days and concentration, demonstrating that a significant amount of Hg crossed the placenta. One week after the last exposure, significant amounts of Hg were still present in brain, liver, and kidney of PND 1 neonates. Metallothionein levels in neonatal tissues were not significantly increased by exposure to 4 mg/m(3) Hg0. The total amount of Hg in neonatal brain (ng/brain) continued to increase after termination of inhalation exposure, suggesting a redistribution of Hg from the dam to neonatal brain. These data demonstrate that inhaled Hg0 vapor is distributed to all maternal and fetal tissues in a dose-dependent manner. Adverse effects of Hg on developmental outcome occurred only at a concentration that caused maternal toxicity.

AN - 71511706; 11893253 AB - Nuclear workers, oil well loggers, astronauts, air flight crews, and frequent fliers can be exposed to low doses of neutrons, but the long-term human health consequences of neutron exposure are unknown. While few of these exposed populations are suitable for studying the effects of neutron exposure, patients treated with neutron-beam therapy might be a source of information. To assess the feasibility of conducting a multi-center international study of the late effects of neutron therapy, we surveyed 23 cancer centers that had used neutron beam therapy. For the 17 responding institutions, only 25% of the patients treated with neutrons (2,855 of 11,191) were alive more than 2 years after treatment. In a two-center U.S. pilot study of 484 neutron-treated cancer patients, we assessed the feasibility of obtaining radiotherapy records, cancer incidence and other follow-up data, and of estimating patient organ doses. Patients were treated with 42 MeV neutrons between 1972 and 1989. Applying a clinical equivalence factor of 3.2 for neutrons, total average organ doses outside the treatment beam ranged from 0.14 to 0.29 Gy for thyroid, 0.40 to 2.50 Gy for breast, 0.63 to 2.35 Gy for kidney, and 1.12 to 1.76 Gy for active bone marrow depending upon the primary cancer treatment site. We successfully traced 97% of the patients, but we found that patient survival was poor and that chemotherapy was not confirmable in a quarter of the patients. Based on our findings from the international survey and the feasibility study, we conclude that a large investigation could detect a fivefold or higher leukemia risk, but would be inadequate to evaluate the risk of solid cancers with long latent periods and therefore would likely not be informative with respect to neutron-related cancer risk in humans.

Neurochemical, therapeutic and adverse effects. AN - 71505289; 11888573 AB - This review summarizes the neurochemical, therapeutic and adverse effects of serotonin (5-HT) releasing agents. The 5-HT releaser (plus minus)-fenfluramine is composed of two stereoisomers, (+)-fenfluramine and (minus sign)-fenfluramine, which are N-de-ethylated to yield the metabolites, (+)-norfenfluramine and (minus sign)-norfenfluramine. Fenfluramines and norfenfluramines are 5-HT transporter substrates and potent 5-HT releasers. Other 5-HT releasing agents include m-chlorophenylpiperazine (mCPP), a major metabolite of the antidepressant drug trazodone. Findings from in vitro and in vivo studies support the hypothesis that fenfluramines and mCPP release neuronal 5-HT via a non-exocytotic carrier-mediated exchange mechanism involving 5-HT transporters. (+)-Norfenfluramine is a potent 5-HT(2B) and 5-HT(2C) receptor agonist. The former activity may increase the risk of developing valvular heart disease (VHD), whereas the latter activity is implicated in the anorectic effect of systemic fenfluramine. Anorectic agents that increase the risk of developing primary pulmonary hypertension (PPH) share the common property of being 5-HT transporter substrates. However, these drugs vary considerably in their propensity to increase the risk of PPH. In this regard, neither trazodone nor mCPP is associated with PPH. Similarly, although some 5-HT substrates can deplete brain 5-HT (fenfluramine), others do not (mCPP). In addition to the established indication of obesity, 5-HT releasers may be helpful in treating psychiatric problems such as drug and alcohol dependence, depression and premenstrual syndrome. Viewed collectively, it seems possible to develop new medications that selectively release 5-HT without the adverse effects of PPH, VHD or neurotoxicity. Such agents may have utility in treating a variety of psychiatric disorders.

Self-perceived survival ability & reproductive fitness (SPFit) is proposed as a human psychobiological construct that prioritizes & organizes (ie, motivates) behavior, but is highly vulnerable to temporary, artificial activation by drugs of abuse. Autoshaping/sign-tracking/feature positive phenomena are proposed to underlie the development of craving & expectations about drugs as the individual learns that abused drugs will easily & reliably inflate SPFit. The cortico-mesolimbic dopamine system & its modulating interconnections are viewed as the biological substrate of SPFit; it is proposed to be a survival & reproductive motivation system rather than a reward center or reward pathway. Finally, the concept of modularity of mind is applied to the SPFit construct. Although considerable empirical data are consistent with the theory, new research is needed to test specific hypotheses derived from SPFit theory. 3 Tables, 2 Figures, 93 References.

Previous studies showed that the virucidal protein cyanovirin-N (CV-N) bound to both gpl20 and gp4l, and that this binding was associated with its antiviral activity. We constructed an HTS assay based on the interaction of europium-labeled CV-N with recombinant glycosylated gp4l ectodomain to support identification of small-molecule mimetics of CV-N that might be developed as antiviral drug leads. Primary screening of over 107,000 natural product extracts in the assay yielded 347 confirmed hits. Secondary assays eliminated extracts that bound directly to labeled CV-N or for which the simple sugars mannose and N-acetylglucosamine blocked the interaction with gp4l (lectin activity). Extracts were further prioritized based on anti-HIV activity and other biological, biochemical, and chemical criteria. The distribution of source organism taxonomy of active extracts was analyzed, as was the cross-correlation of activity between the CV-N-gp4l binding competition assay and the previously reported CV-N-gpl20 binding competition assay. A limited set of extracts was selected for bioassay-guided fractionation.

AN - 1859367704; 11927050 AB - Although highly active antiretroviral therapy suppresses HIV replication resulting in extraordinary clinical benefits, toxicity, adherence difficulties, and the monetary cost of medications limit the long-term effectiveness and availability of therapy for many HIV-infected individuals. Strategies to interrupt therapy have been proposed as a means to enhance the sustainability of antiretroviral treatment. Widely different approaches with varied patient populations, theoretical concepts, and clinical designs are frequently lumped together as "structured treatment interruptions." This review summarizes the approaches and risks of treatment interruptions in HIV infection. Currently, none of these strategies can be recommended in standard clinical practice.

Nevertheless, immune effector cells induced peripherally can be recruited into the central nervous system. Active immunotherapy of intracranial malignancies is thus potentially feasible. In this study we describe a vaccine regimen, based on bone marrow-derived dendritic cells pulsed with the RNA derived from GL261 glioma cells that induces a specific T cell response and protection against intracerebrally implanted GL261 tumors. Immunohistochemical analysis of brain tumors from vaccinated mice was characterized by pronounced intratumoral infiltrates predominantly of CD4 super(+) as well as CD8 super(+) T cells. The efficacy of the vaccine was improved further by administration of recombinant interleukin-12 into the vaccine regimen.

These observations, based on immunoreactivity of total Rb rather than hypophosphorylated protein, do not address the relationship between functional Rb and indicators of an aggressive transformed cellular phenotype. We hypothesized that the distribution of functional Rb and the kinetics of Rb phosphorylation would differ between cell lines representing immortalized mammary epithelium (MCF10A), differentiated nonmetastatic mammary adenocarcinoma (MCF-7), and poorly differentiated, highly metastatic mammary adenocarcinoma (MDA-MB-231) and that these differences would be informative of the cellular phenotype. Direct immunofluorescence microscopy was used to compare qualitatively the subcellular localization of total and hypophosphorylated Rb protein in synchronized and asynchronous cells. This technique was also used to quantitatively assess the amounts of hypophosphorylated Rb throughout the cell cycle in these representative cell lines. Total Rb stained more prominently than hypophosphorylated Rb in the nucleus of all asynchronous cells. Rb phosphorylation was more rapid in MCF-7 cells than in MCF10A cells, whereas Rb dephosphorylation appeared deregulated in MDA-MB-231 cells. We conclude that assessment of hypophosphorylated Rb may be more useful than assessment of total Rb for the evaluation of transformed breast adenocarcinoma phenotypes.

A death certificate based case-control study of mortality was conducted into five cancers: female breast, ovarian, colon, prostate, and non-melanoma skin cancer (as a positive control) to examine associations with residential and occupational exposure to sunlight. Cases were all deaths from these cancers between 1984 and 1995 in 24 states of the United States. Controls, which were age frequency matched to a series of cases, excluded deaths from cancer and certain neurological diseases. Multiple logistic regression was used in a model that included age, sex, race, residential exposure to sunlight (based on region), and socioeconomic status, occupational exposure to sunlight, and physical activity (the last three based on usual occupation). Residential exposure to sunlight was negatively and significantly associated with mortality from female breast, ovarian, prostate, and colon cancer. Only female breast and colon cancer, however, also showed significant negative associations with jobs with the highest occupational exposure to sunlight (odds ratio (OR) 0.82 (95% confidence interval (95% CI) 0.70 to 0.97) for female breast cancer; OR 0.90 (95% CI 0.86 to 0.94) for colon cancer). For both cancers, the negative association with occupational sunlight was greatest in the geographical region of highest exposure to sunlight and was independent of physical activity on the job. Non-melanoma skin cancer, as expected, was positively associated with both residential and occupational sunlight. In this exploratory study, unlike mortality from non-melanoma skin cancer, mortality from female breast cancer and colon cancer were negatively associated with both residential and occupational sunlight.

Fourteen juvenile DM patients with inactive to moderately active, stable disease (age range 7-17 years) and 14 age- and sex-matched controls performed a maximal exercise test using a cycle ergometer. Oxygen uptake and power were measured at peak exercise (VO sub(2peak) and W sub(peak), respectively) and at anaerobic threshold (AT and W sub(AT)). Juvenile DM disease activity and damage were also assessed. Patients with juvenile DM had significantly reduced VO sub(2peak) (19.6 ml O sub(2)/kg/minute in juvenile DM versus 31.1 ml O sub(2)/kg/minute in controls), peak heart rate (166 versus 184 beats per minute), W sub(peak) (1.6 versus 2.7 watts/kg), AT (11.1 versus 18.0 ml O sub(2)/kg/minute) and W sub(AT) (0.6 versus 1.4 watts/kg), compared to controls (P less than or equal to 0.05 for each). Aerobic exercise parameters correlated with physician global disease activity and damage, T1-weighted magnetic resonance imaging, and Childhood Myositis Assessment Scale scores (r sub(s) = 0.58-0.82, P less than or equal to 0.05). Patients with juvenile DM with a range of disease activity have a decreased aerobic and work capacity compared to healthy children. Aerobic exercise limitation in juvenile DM correlates best with measures of disease damage (global damage assessment, T1-weighted magnetic resonance imaging, and disease duration). Aerobic exercise testing may be valuable in the assessment of physical endurance, and aerobic training may be indicated as part of the therapeutic regimen in myositis patients with inactive to moderately active, stable disease.

To take advantage of the abundant data set for the acute inhalation toxicity of phosgene, methods for exposure-response analysis that use more data than the traditional no-observed-adverse-effect level approach were used to perform an exposure-response assessment for phosgene. Categorical regression is particularly useful for acute exposures due to the ability to combine studies of various exposure durations, and thus provide estimates of effect severity for a range of both exposure concentrations and durations. Results from the categorical regression approach were compared to those from parametric curve fitting models (i.e., benchmark concentration models) that make use of information from an entire dose-response, but only for one exposure duration. While categorical regression analysis provided results that were comparable to benchmark concentration results, categorical regression provides an improvement over that technique by accounting for the effects of both exposure concentration and duration on response. The other major advantage afforded by categorical regression is the ability to combine studies, allowing the quantitative use of a larger data set, which increases confidence in the final result.

Conjugates with carbohydrate-to-carrier molar ratios of 15.5: 1, 9.2: 1, and 4.6: 1 were tested for immunogenicity and efficacy in mice. The role of preimmunity to BSA and the use of adjuvant in the generation of the serologic response to the O-specific polysaccharide and protection against virulent V. cholerae was examined. Preimmunity to BSA did not affect the anti-Ogawa titers but seemed to enhance the protective capacity of antiserum. All 3 conjugates were immunogenic, but adjuvant was effective at inducing higher and earlier antibody responses. In tertiary serum samples, a correlation was found between vibriocidal activity and protection. The protective capacity of antiserum was evident in serum from mice immunized with all conjugates, but it was highest in the groups that received the conjugate with the lowest level of substitution. Further studies are required to increase understanding of the reason for differential protection.

It is a secreted nontoxic protein with a molecular weight of 83 kDa and is the major component of the currently licensed human vaccine for anthrax. Due to limitations found in the existing vaccine formulation, it has been proposed that genetically modified PA may be more effective as a vaccine. The expression and the stability of two recombinant PA (rPA) variants, PA-SNKE- Delta FF-E308D and PA-N657A, were studied. These proteins were expressed in the nonsporogenic avirulent strain BH445. Initial results indicated that PA-SNKE- Delta FF-E308D, which lacks two proteolysis-sensitive sites, is more stable than PA-N657A. Process development was conducted to establish an efficient production and purification process for PA-SNKE- Delta FF-E308D. pH, media composition, growth strategy and protease inhibitors composition were analyzed. The production process chosen was based on batch growth of B. anthracis using tryptone and yeast extract as the only source of carbon, pH control at 7.5, and antifoam 289. Optimal harvest time was 14-18 h after inoculation, and EDTA (5 mM) was added upon harvest for proteolysis control. Recovery of the rPA was performed by expanded-bed adsorption (EBA) on a hydrophobic interaction chromatography (HIC) resin, eliminating the need for centrifugation, microfiltration and diafiltration. The EBA step was followed by ion exchange and gel filtration. rPA yields before and after purification were 130 and 90 mg/l, respectively. The purified rPA, without further treatment, treated with small amounts of formalin or adsorbed on alum, induced, high levels of IgG anti-PA with neutralization activities.

Unexpectedly, a large number of genes (nearly 30% of all genes) displayed significant changes in their expression level. Analysis and classification of expression profiles of the corresponding genes allowed us to assign this large number of genes into one or two dozen small clusters of genes with similar expression profiles. This assignment allowed us to describe systematically the changes in the level of gene expression in response to DNA damage. Among the damage-induced genes, more than 100 are novel. From those genes involved in DNA metabolism that have not previously been shown to be induced by DNA damage, the mutS gene involved in mismatch repair is especially noteworthy. In addition to the SOS response, we observed the induction of other stress response pathways, such as those of oxidative stress and osmotic protection. Among the genes that are downregulated in response to DNA damage are numerous protein biosynthesis genes. Analysis of the gene expression data highlighted the essential involvement of sigma super(s) -regulated genes and the general stress response network in the response to DNA damage.

The profile of fatty acids synthesized during exposure to benzoic, nicotinic, or pyrazinoic acids, as well as that observed during intracellular hydrolysis of the corresponding amides, was not a direct consequence of modulation of fatty acid synthesis by these compounds but reflected the response to inorganic acid stress. Analysis of fatty acid synthesis in crude mycobacterial cell extracts demonstrated that pyrazinoic acid failed to directly modulate the fatty acid synthase activity catalyzed by fatty acid synthase I (FAS-I). However, fatty acid synthesis was irreversibly inhibited by 5-chloro-pyrazinamide in a time- dependent fashion. Moreover, we demonstrate that pyrazinoic acid does not inhibit purified mycobacterial FAS-I, suggesting that this enzyme is not the immediate target of pyrazinamide.

We report on a lung cancer case-control study in a rural area of China, where many residents live in underground dwellings and burn coal and unprocessed biomass (crop residues, wood, sticks, and twigs) for heating and cooking. We interviewed 846 patients with lung cancer (626 men, 220 women; aged 30 to 75 years) diagnosed between 1994 and 1998, and 1740 population-based controls. The odds ratio for lung cancer associated with coal use compared with that for biomass in the house of longest residence was 1.29 (95% confidence interval, 1.03 to 1.61), adjusted for smoking and socioeconomic status. The risk for lung cancer increased relative to the percentage of time that coal was used over the past 30 years (P = 0.02). Our findings suggest that coal may contribute to the risk of lung cancer in this rural area of China.

In this reaction sequence, hypoxanthine is hydroxylated to xanthine by PH and then xanthine is hydroxylated to uric acid by XDH. PH and XDH, which contain a labile selenium cofactor in addition to a molybdenum cofactor, flavin adenine dinucleotide, and FeS centers, were purified and partially characterized as reported previously. In the present study, the activities of these two enzymes were measured in cells grown in media containing various concentrations of selenite, molybdate, and various purine substrates. The levels of PH protein in extracts were determined by immunoblot assay. The amount of PH protein, as well as the specific activities of PH and XDH, increased when either selenite or molybdate was added to the culture medium. PH levels were highest in the cells cultured in the presence of either adenine or purine. XDH activity increased dramatically in cells grown with either xanthine or uric acid. The apparent increases in protein levels and activities of PH and XDH in response to selenium, molybdenum, and purine substrates demonstrate that these enzymes are tightly regulated in response to these nutrients.

It was recently demonstrated that selenium delivered from selenocysteine by an E. coli NifS- like protein could replace free selenide in the in vitro SPS assay for selenophosphate formation (G. M. Lacourciere, H. Mihara, T. Kurihara, N. Esaki, and T. C. Stadtman, J. Biol. Chem. 275:23769-23773, 2000). During growth of E. coli in the presence of 0.1 mu M super(75)SeO sub(3) super(2-) and increasing amounts of L-selenocysteine, a concomitant decrease in super(75)Se incorporation into formate dehydrogenase H and nucleosides of bulk tRNA was observed. This is consistent with the mobilization of selenium from L-selenocysteine in vivo and its use in selenophosphate formation. The ability of E. coli to utilize selenocysteine as a selenium source for selenophosphate biosynthesis in vivo supports the participation of the NifS-like proteins in selenium metabolism.

AN - 71578828; 11937093 AB - A continuing challenge for studies in the neurobiology of drug abuse is to identify and characterize long-lived neuroadaptations that can trigger craving and relapse. We previously reported that rats that had actively self-administered methamphetamine for 5 weeks and were then withdrawn from methamphetamine for 24 h showed marked decreases in somatodendritic dopamine D(2) autoreceptor levels in the ventral tegmental area and median and dorsal part of the substantia nigra zona compacta with a corresponding down-regulation of dopamine D(1) receptors in the shell of the nucleus accumbens. The purpose of the present study was to determine whether neuroadaptive changes in dopamine receptors or transporters in the brains of rats withdrawn for 24 h from chronic methamphetamine self-administration are persistent changes that can be demonstrated long after withdrawal. A "yoked" procedure was used in which rats were tested simultaneously in groups of three, with only one rat actively self-administering methamphetamine while the other two received yoked injections of either methamphetamine or saline. In vitro quantitative autoradiography was used to determine densities of dopamine uptake sites and dopamine D(1) and D(2) receptors in different brain regions following 7- and 30-day periods of withdrawal from chronic methamphetamine self-administration. No changes in dopamine transporter and dopamine receptor numbers were detected in any brain region examined in rats self-administering methamphetamine compared with littermates receiving yoked infusions of either methamphetamine or saline. Thus, neuroadaptive changes in densities of dopamine receptors or transporters in certain brain areas may contribute to the reinforcing effects of methamphetamine during the acquisition and maintenance phases of self-administration, but do not appear to contribute to the long-lasting neuroadaptive effects of chronic methamphetamine self-administration, which may trigger craving and relapse.

AN - 71542966; 11805109 AB - Drug toxicities associated with HAART lend urgency to the development of new anti-HIV therapies. Inhibition of viral replication at the entry stage of the viral life cycle is an attractive strategy because it prevents de novo infection. Soluble CD4 (sCD4), the first drug in this class, failed to suppress viral replication in vivo. At least three factors contributed to this failure: sCD4 demonstrated poor neutralizing activity against most primary isolates of HIV in vitro; it demonstrated an intrinsic capacity to enhance viral replication at low concentrations; and it exhibited a relatively short half-life in vivo. Many anti-gp120 monoclonal antibodies, including neutralizing monoclonal antibodies also enhance viral replication at suboptimal concentrations. Advances in our understanding of the events leading up to viral entry suggest strategies by which this activity can be diminished. We hypothesized that by constructing a sCD4-based molecule that is large, binds multiple gp120s simultaneously, and is highly avid toward gp120, we could remove its capacity to enhance viral entry. Here we describe the construction of a polymeric CD4-IgG1 fusion protein. The hydrodynamic radius of this molecule is approximately 12 nm. It can bind at least 10 gp120 subunits with binding kinetics that suggest a highly avid interaction toward virion-associated envelope. This protein does not enhance viral replication at suboptimal concentrations. These observations may aid in the design of new therapeutics and vaccines.

AN - 71599327; 11948401 AB - Retinoic acid (RA) inhibits tumor promotion in many models in vivo and in vitro, among them mouse epidermal JB6 cells. RA treatment suppresses 12-O-tetradecanoylphorbol-13-acetate (TPA) induced AP-1 activity, an activity that is required for transformation of JB6 P+ cells. The molecular mechanism of AP-1 transrepression by retinoids is unclear, especially as related to inhibition of transformation. Overexpression of AP-1 components did not rescue TPA induced AP-1 activation nor did a GST pull down experiment implicate direct binding, thus rendering unlikely both a Jun/Fos-RA-RAR direct interaction and a Jun/Fos sequestration mechanism. Overexpression of p300, SRC-1 or pCAF did not abrogate AP-1 suppression by RA, thus arguing against coactivator competition. Overexpression of the corepressor silencing mediator for retinoic acid and thyroid hormone receptors (SMRT) suppressed AP-1 activity. However, SMRT but not RA inhibited cJun transactivation, suggesting SMRT does not mediate RA transrepression. RA treatment also did not block TPA induced ERK phosphorylation, Jun/Fos family protein expression except for cFos, or DNA binding of the AP-1 complex. The transcriptional activities of full-length JunB and full-length Fra-1, but not the transactivation domain fusions, were increased by TPA treatment and suppressed by RA. Since these full-length fusions have bzip domains, the results suggest that JunB and/or Fra-1-containing dimers may constitute one target of RA for transrepression of AP-1.

AN - 71595210; 11948403 AB - Hepatocyte growth factor (HGF) regulates various physiological and developmental processes in concert with other growth factors, cytokines and hormones. We examined interactions between cell signaling events elicited by HGF and the cytokine interleukin (IL)-4, in the IL-3-dependent murine myeloid cell line 32D transfected with the human HGF receptor, c-Met. HGF was a potent mitogen in these cells, and prevented apoptosis in response to IL-3 withdrawal. IL-4 showed modest anti-apoptotic activity, but no significant mitogenic activity. IL-4 synergistically enhanced HGF-stimulated DNA synthesis, whereas only additive prevention of apoptosis was observed. IL-4 did not enhance HGF-dependent tyrosine phosphorylation of c-Met or Shc. In contrast, HGF-stimulated activation of MAP kinases was enhanced by IL-4, suggesting that the IL-4 and HGF signaling pathways converge upstream of these events. Although phosphatidylinositol 3-kinase (PI3K) inhibitors diminished HGF-induced mitogenesis, anti-apoptosis, and MAP kinase activation, IL-4 enhanced HGF signaling persisted even in the presence of these inhibitors. IL-4 enhancement of HGF signaling was partially blocked in 32D/c-Met cells treated with inhibitors of MEK1 or c-Src kinases, completely blocked by expression of a catalytically inactive mutant of Janus kinase 3 (Jak3), and increased in 32D/c-Met cells overexpressing STAT6. Our results suggest that the IL-4 and HGF pathways converge at multiple levels, and that IL-4-dependent Jak3 and STAT6 activities modulate signaling events independent of PI3K to enhance HGF-dependent mitogenesis in myeloid cells, and possibly other common cellular targets.

AN - 71505346; 11888707 AB - In order to examine whether biomarkers of cytogenetic damage and susceptibility, such as spontaneous and mitomycin C-induced sister chromatid exchange (SCE) can predict cancer development, a nested case-control study was performed in a blackfoot endemic area with known high cancer risk. A cohort of 686 residents was recruited from three villages in the arseniasis area. Personal characteristics were collected and venous blood was drawn for lymphocyte culture and stored in a refrigerator. The vital status and cancer development was followed using the National Death Registry, Cancer Registry, and Blackfoot Disease Registry. The follow up period was from August 1991 to July 1997. During this 6-year-period, 55 residents developed various types of cancer. Blood culture samples from 23 of these subjects were unsuitable for spontaneous SCE experiments and 45 of these subjects were unsuitable for mitomycin C-induced SCE experiments due to improper storage. Finally, a total of 32 cancer cases had cytogenetic samples that could be analyzed. About 32 control subjects were selected from those who did not develop cancer in the study period and these subjects were matched to cases by sex, age, smoking habits, and residential area. The results showed that there was no significant difference in the frequencies of spontaneous and mitomycin C-induced SCE between the case and control groups. There was also no significant difference in the net difference of spontaneous and mitomycin C-induced SCE between the case and control groups. These results suggest that SCEs, either spontaneous or mitomycin C-induced, might not be good markers to predict cancer risk.

AN - 71532496; 11751890 AB - Using models of serum deprivation and 1-methyl-4-phenylpyridinium (MPP(+)), we investigated the mechanism by which thioredoxin (Trx) exerts its antiapoptotic protection in human neuroblastoma cells (SH-SY5Y) and preconditioning-induced neuroprotection. We showed that SH-SY5Y cells are highly sensitive to oxidative stress and responsive to both extracellularly administered and preconditioning-induced Trx. Serum deprivation and MPP(+) produced an elevation in the hydroxyl radicals, malondialdehyde and 4-hydroxy-2,3-nonenal (HNE), causing the cells to undergo mitochondria-mediated apoptosis. Trx in the submicromolar range blocked the observed apoptosis via a multiphasic protection mechanism that includes the suppression of cytochrome c release (most likely via the induction of Bcl-2), the inhibition of procaspase-9 and procaspase-3 activation, and the elevated level of Mn-SOD. The reduced form of Trx suppresses the serum-free-induced hydroxyl radicals, lipid peroxidation, and apoptosis, indicating that H(2)O(2) is removed by Trx peroxidase. The participation of Trx in preconditioning-induced neuroprotection is supported by the observation that inhibition of Trx synthesis with antisense oligonucleotides or of Trx reductase drastically reduced the hormesis effect. This effect of Trx-mediated hormesis against oxidative stress-induced apoptosis is striking. It induced a 30-fold shift in LD(50) in the MPP(+)-induced neurotoxicity.

However, fetal sensitivity and dose-response characteristics with regard to transplacental mutagenesis by X-rays have never been quantified. In the current experiment, pregnant Syrian hamsters at day 12 of gestation were irradiated with 300-kV X-rays. Twenty-four hours later, the fetuses were removed and their cells were allowed a 5 day expression time in culture. They were then seeded for colony formation and also for mutation selection by 6-thioguanine (6-TG). Mutation frequency was linear over the entire dose range, 10-600 R. The average induced 6-TG mutant frequency was 4.7 x 10 super(-7) per R. These results suggest that fetal cells are highly sensitive to induction of mutations by X-rays, and that a no-effect threshold is not likely. The 10 R dose caused a 25-fold increase in mutation frequency over the historical control, 45 x 10 super(-7) versus 1.8 x 10 super(-7) , an increase per R of 2.5-fold. Increased risk of childhood cancer related to obstetrical transabdominal X-ray has also been estimated at 2.5-fold per R. Thus, our results are consistent with mutation contributing to this effect.

AN - 71549660; 11867754 AB - It has been argued that genetic instability is required to generate the myriad mutations that fuel tumor initiation and progression and, in fact, patients with heritable cancer susceptibility syndromes harbor defects in specific genes that normally maintain DNA integrity. However, the vast majority of human cancers arise sporadically, in the absence of deficiencies in known "mutator" genes. We used a cII-based mutation detection assay to show that the mean frequency of forward mutations in primary mammary adenocarcinomas arising in mouse mammary tumor virus-c-erbB2 transgenic mice harboring multiple copies of the lambda bacteriophage genome was significantly higher than in aged-matched, wild-type mammary tissue. Analysis of the cII mutational spectrum within the mammary tumor genomic DNA demonstrated a >6-fold elevation in transversion mutation frequency, resulting in a highly unusual inversion of the transition/transversion ratio characteristic of normal epithelium; frameshift mutation frequencies were unaltered. Arising oncogenic point mutations within the c-erbB2 transgene of such tumors were predominantly transversions as well.

AN - 71538950; 11904413 AB - 3-Nitrotyrosyl adducts in proteins have been detected in a wide range of diseases. The mechanisms by which reactive nitrogen oxide species may impede protein function through nitration were examined by using a unique model system, which exploits a critical tyrosyl residue in the fluorophoric pocket of recombinant green fluorescent protein (GFP). Exposure of purified GFP suspended in phosphate buffer to synthetic peroxynitrite in either 0.5 or 5 microM steps resulted in progressively increased 3-nitrotyrosyl immunoreactivity concomitant with disappearance of intrinsic fluorescence (IC(50) approximately 20 microM). Fluorescence from an equivalent amount of GFP expressed within intact MCF-7 tumor cells was largely resistant to this bolus treatment (IC(50) > 250 microM). The more physiologically relevant conditions of either peroxynitrite infusion (1 microM/min) or de novo formation by simultaneous, equimolar generation of nitric oxide (NO) and superoxide (e.g., 3-morpholinosydnonimine; NONOates plus xanthine oxidase/hypoxanthine, menadione, or mitomycin C) were examined. Despite robust oxidation of dihydrorhodamine under each of these conditions, fluorescence decrease of both purified and intracellular GFP was not evident regardless of carbon dioxide presence, suggesting that oxidation and nitration are not necessarily coupled. Alternatively, both extra- and intracellular GFP fluorescence was exquisitely sensitive to nitration produced by heme-peroxidase/hydrogen peroxide-catalyzed oxidation of nitrite. Formation of nitrogen dioxide (NO(2)) during the reaction between NO and the nitroxide 2-phenyl-4,4,5,5-tetramethylimidazole-1-oxyl 3-oxide indicated that NO(2) can enter cells and alter peptide function through tyrosyl nitration. Taken together, these findings exemplified that heme-peroxidase-catalyzed formation of NO(2) may play a pivotal role in inflammatory and chronic disease settings while calling into question the significance of nitration by peroxynitrite.

AN - 71531600; 11891320 AB - The recent development of HIV-1 lentiviral vectors is especially useful for gene transfer because they achieve efficient integration into nondividing cell genomes and successful long-term expression of the transgene. These attributes make the vector useful for gene delivery, mutagenesis, and other applications in mammalian systems. Here we describe two HIV-1-based lentiviral vector derivatives, pZR-1 and pZR-2, that can be used in gene-trap experiments in mammalian cells in vitro and in vivo. Each lentiviral gene-trap vector contains a reporter gene, either beta-lactamase or enhanced green fluorescent protein (EGFP), that is inserted into the U3 region of the 3' long terminal repeat. Both of the trap vectors readily integrate into the host genome by using a convenient infection technique. Appropriate insertion of the vector into genes causes EGFP or beta-lactamase expression. This technique should facilitate the rapid enrichment and cloning of the trapped cells and provides an opportunity to select subpopulations of trapped cells based on the subcellular localization of reporter genes. Our findings suggest that the reporter gene is driven by an upstream, cell-specific promoter during cell culture and cell differentiation, which further supports the usefulness of lentivirus-based gene-trap vectors. Lentiviral gene-trap vectors appear to offer a wealth of possibilities for the study of cell differentiation and lineage commitment, as well as for the discovery of new genes.

AN - 71618761; 11958479 AB - The neurotransmitter norepinephrine is metabolized by monoamine oxidase into an aldehyde intermediate that is further metabolized to the stable glycol derivative, 3,4-dihydroxyphenylglycol (DHPG). In this study, the possible role of aldose reductase in reducing this aldehyde intermediate in human sympathetic neurons has been examined. DHPG is formed when norepinephrine is incubated with aldose reductase in the presence of monoamine oxidase. DHPG metabolism is inhibited by the monoamine oxidase inhibitor, pargyline which prevents the deamination of norepinephrine, and by the aldose reductase inhibitor AL 1576, which inhibits DHPG formation without affecting the deamination of norepinephrine. Although similar formation of DHPG was observed with human liver aldehyde reductase, the production of DHPG was more effective with aldose reductase than aldehyde reductase. Two peaks of reductase activity corresponding to aldose reductase and aldehyde reductase were observed when sympathetic ganglia were chromatofocused. Molecular modeling studies indicate that the energy-minimized structure of 3,4-dihydroxymandelaldehyde bound to aldose reductase is similar to that of glyceraldehyde where the 2'-hydroxyl group forms hydrogen bonds with Trp111 and NADPH. These results suggest that aldose reductase may be important in metabolizing the potentially toxic aldehyde intermediate formed from norepinephrine in human sympathetic ganglia.

The Fhit protein is believed to inhibit tumor growth by inducing apoptosis through interaction with diadenosine triphosphate (Ap sub(3)A). The latter is first sequestered and eventually hydrolyzed by Fhit to ADP and AMP. Thus, the balance between the cellular Ap sub(3)A level and Fhit enzymatic activity may affect cell death or survival. Increasing the Ap sub(3)A level, e.g., by inhibition of the enzyme, should prevent apoptosis and thus sustain tumorigenesis. To test if certain carcinogenic transition metals could inhibit the enzymatic activity of Fhit, purified human Fhit protein [30 nM in 1.25 mM poly(vinylpyrrolidone)], expressed in and isolated from E. coli, was incubated at pH 6.8 (50 mM HEPES buffer in 150 mM NaCl) with 120 mu M Ap sub(3)A in the presence of 5 mM Mg(II) (activating cation) and 0-100 mu M Ni(II), Cu(II), Zn(II), Cd(II), Co(II), Cr(III), As(III), or As(V). The reaction mixtures were analyzed by HPLC. The results revealed a strong inhibitory potential of Cu(II) [0.4], followed by Ni(II) [3.5] greater than or equal to Zn(II) [7.0] >> Cr(III) [73] > Cd(II) [98] >> Co(II) [432] [the numbers in brackets are IC sub(50) values, mu M]. As(III) and As(V) had no effect. As revealed by spectrophotometry, mass spectrometry, and gel electrophoresis, the exceptionally strong inhibition by Cu(II) was associated with Fhit dimerization through formation of a disulfide bond. The other metals and also H sub(2)O sub(2) and NO did not cause the dimerization. Thus, the effect of Cu(II) must be due to its reaction with Cys-39 bearing the only thiol group in Fhit monomer. Since Cys-39 is not readily accessible in the Fhit molecule, the reaction is most likely facilitated by conformational changes which follow the coordination of Cu(II) by the surface histidines 35, 94, and/or 96. The observed inhibition of Fhit may be mechanistically involved in metal-mediated toxicity and carcinogenesis.

AN - 71615712; 11958953 AB - This study examined the effect of acute cadmium on stress-related gene expression and free radical production in wild-type and metallothionein-I/II-null (MT-null) mice. Atlas Toxicology arrays showed that acute cadmium (40 micromol/kg as CdCl(2), ip for 3 h) markedly increased the expression of genes encoding heat-shock proteins, heme oxygenase-1, and genes in response to DNA damage/repair. The expression of genes encoding cytochrome P450 enzymes, UDP-glucuronosyltransferases, Mn-superoxide dismutase, and catalase was suppressed by cadmium. MT-null mice were more sensitive than wild-type mice to cadmium-induced, stress-related gene expression, in accord with greater activation of transcription factor AP-1 and phosphorylated JNK and ERK. To evaluate free radical production, mice were simultaneously given the spin trap agent, N-tert-butyl-alpha-phenylnitrone (PBN, 250 mg in DMSO/kg, ip) with cadmium, and livers were removed 30 min later for PBN-trapped radical extraction with chloroform:methanol (2:1), and detected with electron spin resonance (ESR). Cadmium treatment caused detectable ESR signals for PBN adducts as well as lipid peroxidation in the liver similarly in both wild-type and MT-null mice. Thus, the mechanism of acute cadmium toxicity involves multiple facets including oxidative damage and aberrant gene expression, and absence of MT exacerbates Cd-induced aberrant gene expression.

AN - 71550635; 11920298 AB - Treatment of onchocerciasis with diethylcarbamazine (DEC) or ivermectin is associated with a posttreatment reaction characterized by fever, tachycardia, hypotension, lymphadenopathy, and pruritus. To investigate the role of the Wolbachia bacterial endosymbiont of Onchocerca volvulus in these reactions, serum samples collected before and after treatment with either anthelmintic were assessed for evidence of Wolbachia DNA. By use of real-time quantitative polymerase chain reaction, Wolbachia DNA was detected in both groups-with significantly higher levels in those who received DEC (P <.0001). In the ivermectin group, there was a significant correlation between levels of bacterial DNA and serum tumor necrosis factor-alpha (P =.013). Peak DNA levels correlated with reaction scores (P =.048). Significant correlations were also seen between Wolbachia DNA and the antibacterial peptides calprotectin (P =.021) and calgranulin B (P <.0001). These findings support a role for Wolbachia products in mediating the inflammatory responses seen following treatment of onchocerciasis and suggest new targets for modulating these reactions.

AN - 71538849; 11916383 AB - The crystal structure of a post-translationally modified form of eosinophil-derived neurotoxin (EDN) with four extra residues on its N terminus ((-4)EDN) has been solved and refined at atomic resolution (1 A). Two of the extra residues can be placed unambiguously, while the density corresponding to two others is poor. The modified N terminus appears to influence the position of the catalytically important His129, possibly explaining the diminished catalytic activity of this variant. However, (-4)EDN has been shown to be cytotoxic to a Kaposi's sarcoma tumor cell line and other endothelial cell lines. Analysis of the structure and function suggests that the reason for cytotoxicity is most likely due to cellular recognition by the N-terminal extension, since the intrinsic activity of the enzyme is not sufficient for cytotoxicity and the N-terminal extension does not affect the conformation of EDN.

AN - 71514547; 11891694 AB - Congenital disorders of glycosylation (CDG) are a group of metabolic disorders with multisystemic involvement characterized by abnormalities in the synthesis of N-linked oligosaccharides. The most common form, CDG-Ia, resulting from mutations in the gene encoding the enzyme phosphomannomutase (PMM2), manifests with severe abnormalities in psychomotor development, dysmorphic features and visceral involvement. While this disorder is panethnic, we present the first cases of CDG-Ia identified in an African American family with two affected sisters. The proband had failure to thrive in infancy, hypotonia, ataxia, cerebellar hypoplasia and developmental delay. On examination, she also exhibited strabismus, inverted nipples and an atypical perineal fat distribution, all features characteristic of CDG-Ia. Direct sequencing demonstrated that the patient had a unique genotype, T237M/c.565-571 delAGAGAT insGTGGATTTCC. The novel deletion-insertion mutation, which was confirmed by subcloning and sequencing of each allele, introduces a stop codon 11 amino acids downstream from the site of the deletion. The presence of this deletion-insertion mutation at cDNA position 565 suggests that this site in the PMM2 gene may be a hotspot for chromosomal breakage.

Paper No. 21 N1 - Last updated - 2010-05-03 ER - TY - JOUR T1 - Dynamics of a protein polymer: the assembly and disassembly pathways of the MuB transposition target complex AN - 18298856; 5348373 AB - MuB assembles into a polymer on DNA in the presence of ATP and is directly involved in the selection of an appropriate site on the Escherichia coli chromosome for the insertion of the bacteriophage Mu genome. We have developed an assay using fluorescently tagged proteins to monitor the polymeric state of MuB via fluorescence resonance energy transfer. We show that polymer assembly is initiated by the formation of an ATP-MuB complex. MuB then self-associates into a protomer before binding to DNA. Upon binding to DNA, a dramatic increase in energy transfer is observed, suggesting a conformational change within MuB. Polymer disassembly is much slower than assembly and is greatly stimulated by the MuA transposase. Additionally, MuB is readily exchanged between polymers, and ATP hydrolysis is directly coupled to polymer disassembly. Our data support a model in which a combination of rapid polymer assembly, MuA-mediated disassembly, followed by rapid reassembly of the polymer allows MuB to sample multiple DNA targets until an appropriate site is located for the insertion of the bacteriophage genome.

AN - 71502118; 11882001 AB - In our search for long-acting agents for the treatment of cocaine abuse, a series of optically pure hydroxylated derivatives of 1-[2-[bis(4-fluorophenyl)methoxy]ethyl]-4-(3-phenylpropyl)piperazine (1) and 1-[2-(diphenylmethoxy)ethyl]-4-(3-phenylpropyl)piperazine (2) (GBR 12909 and GBR 12935, respectively) were synthesized and evaluated in vitro and in vivo. The enantiomers of the 2-hydroxylated analogues displayed substantial enantioselectivity. The S enantiomers displayed higher dopamine transporter (DAT) affinity and the R enantiomers were found to interact at the serotonin transporter (SERT) with higher affinity. The two-carbon spacer between the hydroxyl group and the piperazine ring was essential for enantioselectivity, and the length of the alkyl chain between the phenyl group and the piperazine ring influenced binding affinity and selectivity for the DAT and SERT. Phenylethyl analogues had a higher binding affinity for the SERT and a weaker affinity and selectivity for the DAT than the corresponding phenylpropyl analogues. Thus, (S)-(+)-1-[4-[2-[bis(4-fluorophenyl)methoxy]ethyl]piperazinyl]-3-phenylpropan-2-ol (6) displayed the highest affinity to the DAT, and (S)-(+)-1-[4-[2-(diphenylmethoxy)ethyl]piperazinyl]-3-phenylpropan-2-ol (8) had the highest selectivity. The latter (8) is one of the most DAT selective ligands known. In accord with the in vitro data, 6 showed greater potency than 7 in elevating extracellular dopamine levels in a microdialysis assay and in inhibiting cocaine-maintained responding in rhesus monkeys.

AN - 71518758; 11889247 AB - Although botulinum toxin is an effective treatment for focal dystonia, the importance of electromyography (EMG) in identifying muscles and guiding injections is unclear. The authors examined the accuracy of muscle localization in 38 muscles in patients with focal hand dystonia without EMG guidance. Only 37% of needle placement attempts reached the target muscles or muscle fascicles. This study demonstrates that EMG guidance is needed for correct localization of desired muscles.

AN - 71468605; 11857402 AB - The p53 tumor suppressor can induce growth arrest, apoptosis and cell senescence. Not surprisingly, p53 is an appealing target for therapeutic intervention. Although current anticancer agents do not directly interact with p53, these agents (including DNA damaging drugs, antimetabolites, microtubule-active drugs and inhibitors of the proteasome) cause accumulation of wt p53. Depending on the p53 status of cancer cells, diverse therapeutic strategies are under development. These include pharmacological rescue of mutant p53 function and reactivation of wt p53 in E6-expressing cells. For protection of normal cells, strategies range from abrogation of wt p53 induction, thereby decreasing the toxicity of DNA damaging agents, to activation of wt p53-dependent checkpoints, thereby protecting cells against cell cycle-dependent therapeutics.

AN - 71532867; 11756435 AB - Structures of DNA polymerases bound with DNA reveal that the 5'-trajectory of the template strand is dramatically altered as it exits the polymerase active site. This distortion provides the polymerase access to the nascent base pair to interrogate proper Watson-Crick geometry. Upon binding a correct deoxynucleoside triphosphate, alpha-helix N of DNA polymerase beta is observed to form one face of the binding pocket for the new base pair. Asp-276 and Lys-280 stack with the bases of the incoming nucleotide and template, respectively. To determine the role of Lys-280, site-directed mutants were constructed at this position, and the proteins were expressed and purified, and their catalytic efficiency and fidelity were assessed. The catalytic efficiency for single-nucleotide gap filling with the glycine mutant (K280G) was strongly diminished relative to wild type for templating purines (>15-fold) due to a decreased binding affinity for the incoming nucleotide. In contrast, catalytic efficiency was hardly affected by glycine substitution for templating pyrimidines (<4-fold). The fidelity of the glycine mutant was identical to the wild type enzyme for misinsertion opposite a template thymidine, whereas the fidelity of misinsertion opposite a template guanine was modestly altered. The nature of the Lys-280 side-chain substitution for thymidine triphosphate insertion (templating adenine) indicates that Lys-280 "stabilizes" templating purines through van der Waals interactions.

AN - 71505086; 11751931 AB - In the uterus insulin-like growth factor-1 (IGF-1) signaling can be initiated by estradiol acting through its nuclear receptor (estrogen receptor (ER)) to stimulate the local synthesis of IGF-1. Conversely, in vitro studies have demonstrated that estradiol-independent ER transcriptional activity can be induced by IGF-1 signaling, providing evidence for a cross-talk mechanism between IGF-1 and ER. To investigate whether ER alpha is required for uterine responses to IGF-1 in vivo, both wild-type (WT) and ER alpha knockout (alpha ERKO) mice were administered IGF-1, and various uterine responses to IGF-1 were compared. In both WT and alpha ERKO mice, IGF-1 treatment resulted in phosphorylation of uterine IGF-1 receptor (IGF-1R) and formation of an IGF-1R/insulin receptor substrate-1/ phosphatidylinositol 3-kinase signaling complex. In addition, IGF-1 stimulated phosphorylation of uterine Akt and MAPK in both WT and alpha ERKO mice. However, IGF-1 treatment stimulated BrdUrd incorporation and proliferating cell nuclear antigen expression in WT uteri only. To determine whether ER alpha can be activated in vivo by IGF-1 signaling, transgenic mice carrying a luciferase gene driven by two estrogen response elements (ERE-luciferase mice) were utilized. Treatment of ovariectomized ERE-luciferase mice with IGF-1 resulted in an increase in uterine luciferase activity that was attenuated in the presence of the ER antagonist ICI 182,780. Together these data demonstrate that 1) functional signaling proximal to IGF-1R is maintained in the alpha ERKO mouse uterus, 2) ER alpha is necessary for IGF-1 induction of uterine nuclear proliferative responses, and 3) cross-talk between IGF-1R and ER signaling pathways exists in vivo.

AN - 71484781; 11873000 AB - Lipid lowering therapy is used increasingly in persons with HIV infection in the absence of safety data or information on drug interactions with antiretroviral agents. The primary objectives of this study were to examine the effects of ritonavir (RTV) plus saquinavir soft-gel (SQVsgc) capsules on the pharmacokinetics of pravastatin, simvastatin, and atorvastatin, and the effect of pravastatin on the pharmacokinetics of nelfinavir (NFV) in order to determine clinically important drug-drug interactions. Randomized, open-label study in healthy, HIV seronegative adults at AIDS Clinical Trials Units across the USA. Three groups of subjects (arms 1, 2, and 3) received pravastatin, simvastatin or atorvastatin (40 mg daily each) from days 1-4 and 15-18. In these groups, RTV 400 mg and SQVsgc 400 mg twice daily were given from days 4-18. A fourth group (arm 4) received NFV 1250 mg twice daily from days 1-14 with pravastatin 40 mg daily added from days 15-18. Statin and NFV levels were measured by liquid chromatography/tandem mass spectrometry. Fifty-six subjects completed both pharmacokinetic study days. In arms 1-3, the median estimated area under the curves (AUC)(0-24) for the statins were: pravastatin (arm 1, n = 13), 151 and 75 ng.h/ml on days 4 and 18 (decline of 50% in presence of RTV/SQVsgc), respectively (P = 0.005); simvastatin (arm 2, n = 14), 17 and 548 ng.h/ml on days 4 and 18 (increase of 3059% in the presence of RTV/SQVsgc), respectively (P < 0.001); and total active atorvastatin (arm 3, n = 14), 167 and 289 ng.h/ml on days 4 and 18 (increase of 79% in the presence of RTV/SQVsgc), respectively (P < 0.001). In arm 4, the median estimated AUC(0-8) for NFV (24 319 versus 26 760 ng.h/ml; P = 0.58) and its active M8 metabolite (15 565 versus 14 571 ng.h/m; P = 0.63) were not statistically different from day 14 to day 18 (without or with pravastatin). Simvastatin should be avoided and atorvastatin may be used with caution in persons taking RTV and SQVsgc. Dose adjustment of pravastatin may be necessary with concomitant use of RTV and SQVsgc. Pravastatin does not alter the NFV pharmacokinetics, and thus appears to be safe for concomitant use.

All of them belong to a recently identified family of cyclic nucleotide phosphodiesterases. Experiments elucidating folding stability, protein fluorescence, oligomerization behavior, and the effects of substrates were conducted, revealing differences between the plant and the yeast protein. According to CD spectroscopy, the latter protein exhibits an ( alpha + beta ) fold rather than an ( alpha / beta ) fold as found with CPDase (A. thaliana). The redox-dependent structural reorganization recently found for the plant protein by X-ray crystallography could not be detected by CD spectroscopy due to its only marginal effect on the total percentage of helical content. However, in the present study a redox-dependent effect was also observed for the yeast CPDase. The enzymatic activity of wild type CPDase (A. thaliana) as well as of four mutants were characterized by isothermal titration calorimetry and the results prove the requirement of all four residues of the previously identified tandem signature motif for the catalytic function. Within the comparison of the three proteins in this study, the PDase Homolog /RNA ligase (E. coli) shares more similarities with the plant than with the yeast protein.

AN - 71599914; 11943468 AB - Nuclear and mitochondrial DNA are constantly being exposed to damaging agents, from endogenous and exogenous sources. In particular, reactive oxygen species (ROS) are formed at high levels as by-products of the normal metabolism. Upon oxidative attack of DNA many DNA lesions are formed and oxidized bases are generated with high frequency. Mitochondrial DNA has been shown to accumulate high levels of 8-hydroxy-2'-deoxyguanosine, the product of hydroxylation of guanine at carbon 8, which is a mutagenic lesion. Most of these small base modifications are repaired by the base excision repair (BER) pathway. Despite the initial concept that mitochondria lack DNA repair, experimental evidences now show that mitochondria are very proficient in BER of oxidative DNA damage, and proteins necessary for this pathway have been isolated from mammalian mitochondria. Here, we examine the BER pathway with an emphasis on mtDNA repair. The molecular mechanisms involved in the formation and removal of oxidative damage from mitochondria are discussed. The pivotal role of the OGG1 glycosylase in removal of oxidized guanines from mtDNA will also be examined. Lastly, changes in mtDNA repair during the aging process and possible biological implications are discussed.

AN - 71503039; 11877366 AB - Digitalis-like sodium pump ligands (SPLs) effect natriuresis via inhibition of renal tubular Na(+),K(+)-ATPase but may induce vasoconstriction. The present study investigated the potential roles of 2 putative endogenous SPLs, an ouabain-like compound (OLC) and an alpha(1) Na(+),K(+)-ATPase inhibitor, marinobufagenin (MBG), in regulating natriuresis and blood pressure (BP) responses to sustained and acute NaCl loading in Dahl salt-sensitive rats (DS). During 4 weeks of an 8% NaCl diet, DS exhibited a progressive increase in MBG renal excretion (66 +/-13 pmol/24 hours at week 4 versus 11 +/- 1 pmol/24 hours at baseline, n=48), which paralleled an increase in systolic BP (174 +/- 10 mm Hg at week 4 versus 110 +/- 2 mm Hg at baseline). By contrast, OLC excretion peaked at week 1 and returned to baseline levels. Administration of an anti-MBG, but not anti-ouabain antibody, to DS after 3 weeks of a high NaCl diet lowered BP (139 +/- 7 versus 175 +/- 5 mm Hg, P<0.001, n=5). Acute NaCl loading (2 hours) of DS (n=5) increased MBG and OLC excretion and natriuresis. Pretreatment of acutely NaCl-loaded DS with an anti-MBG antibody (n=5) reduced the excretion of sodium and MBG but not that of OLC. An anti-ouabain antibody (n=5) reduced sodium excretion and both OLC and MBG. An initial transient stimulation of OLC induced by NaCl loading of DS precedes an MBG response.

We have investigated in a canine large-animal model whether expression of transduced genes can be recovered in vivo. Mixed-breed dogs had undergone autologous bone marrow transplantation (BMT) with stem cell factor and granulocyte-colony-stimulating factor-mobilized retrovirally marked hematopoietic cells. The bicistronic retroviral vector construct allowed for coexpression of MDR1 and human IL-2 receptor common gamma -chain cDNAs. The latter gene is deficient in X-linked severe combined immunodeficiency. After initial high-level expression, P-glycoprotein and the gamma -chain were undetectable in blood and bone marrow 17 months post-BMT. Six months later, one dog was treated i.v. with 125 mg/m super(2) paclitaxel. Three administrations restored expression of the two linked genes to high levels in blood and bone marrow. Two dogs treated with higher paclitaxel doses died from myelosuppression after the first administration. As determined by flow cytometry, both genes were expressed in granulocytes, monocytes, and lymphocytes of the surviving animal. PCR analysis of DNA from peripheral blood confirmed that the retroviral cDNA was increased after paclitaxel treatment, suggesting enrichment of transduced cells. P-glycoprotein was detectable for more than 1 year after cessation of paclitaxel. Repeated analyses of blood and bone marrow aspirates gave no indication of hematopoietic disturbance after BMT with transduced cells and paclitaxel treatment. In summary, we have shown that with the use of a drug-selectable marker gene, chemotherapy can select for cells that express an otherwise nonselected therapeutic gene in blood and bone marrow.

The initial cell concentration was 4.0 g/L, and there was only significant growth in the fermentation with the highest oxygen availability. In this condition, OUR increased proportionally to cell growth, reaching maximum values from 2.1 to 2.5 g of O sub(2)/(L.h) in the stationary phase when the initial substrate concentration was raised from 50 to 200 g/L, respectively. SOUR showed different behavior, growing to a maximum value coinciding with the beginning of the exponential growth phase, after which point it decreased. The maximum SOUR values varied from 265 to 370 mg of O sub(2)/(g of cell.h), indicating the interdependence of this parameter and the substrate concentration. Although the volumetric productivity dropped slightly from 1.55 to 1.18 g of xylitol/(L.h), the strain producing capacity (g sub(P/X)) rose from 9 to 20.6 g/g when the initial substrate concentration was increased from 50 to 200 g/L. As for the xylitol yield over xylose consumed (g sub(P/S)), there was no significant variation, resulting in a mean value of 0.76 g/g. The results are of interest in establishing a strategy for controlling the dynamic oxygen supply to maximize volumetric productivity.

Here we report a locus for dominant deafness, DFNA36, which maps to human chromosome 9q13-21 in a region overlapping the DFNB7/B11 locus for recessive deafness. We identified eight mutations in a new gene, transmembrane cochlear-expressed gene 1 (TMC1), in a DFNA36 family and eleven DFNB7/B11 families. We detected a 1.6-kb genomic deletion encompassing exon 14 of Tmc1 in the recessive deafness (dn) mouse mutant, which lacks auditory responses and has hair-cell degeneration. TMC1 and TMC2 on chromosome 20p13 are members of a gene family predicted to encode transmembrane proteins. Tmc1 mRNA is expressed in hair cells of the postnatal mouse cochlea and vestibular end organs and is required for normal function of cochlear hair cells.

AN - 85250961; pmid-11867442 AB - It has been shown that the membrane motor in the outer hair cell is driven by the membrane potential. Here we examine whether the motility satisfies the reciprocal relationship, the characteristic of piezoelectricity, by measuring charge displacement induced by stretching the cell with known force. The efficiency of inducing charge displacement was membrane potential dependent. The maximum efficiency of inducing charge displacement by force was approximately 20 fC/nN for 50-microm-long lateral membrane. The efficiency per cell stretching was 0.1 pC/microm. We found that these values are consistent with the reciprocal relationship based on the voltage sensitivity of approximately 20 nm/mV for 50-microm-long cell and force production of 0.1 nN/mV by the cell. We can thus conclude that the membrane motor in the outer hair cell satisfies a necessary condition for piezoelectricity and that the hair cell's piezoelectric coefficient of 20 fC/nN is four orders of magnitude greater than the best man-made material.

AN - 85238073; pmid-11922314 AB - Multiplexing and time averaging of signal are effective noise reduction protocols applied in many analytical measurement systems. The efficacy of these protocols may be reduced by random occurrences of high-magnitude noise that do not conform to the statistical distribution of noise for all other measurements in the data set. This high-magnitude noise, which may have an insignificant probability of occurrence for a single measurement, almost certainly affects data collected in a multichannel, multiplexed modality, such as Fourier transform infrared (FT-IR) spectroscopic imaging employing focal plane array detectors. To recover time-averaging advantages in these cases, we present a general coaddition method that uses two statistical measures, the mean and median of the ensemble of measurements of a signal, to obtain a better estimate of the true signal than that estimated by time averaging alone. This method, termed median filtered time averaging, is shown to be an effective noise removal procedure for FT-IR imaging data. The effects of noise removal on time averaging and multiplexing are examined theoretically and are demonstrated for hyperspectral infrared microspectroscopic imaging data obtained from human skin biopsies by using a rapid data acquisition procedure.

AN - 72057318; 12212660 AB - Perpetrators of domestic violence describe symptoms that are compatible with exaggerated autonomic arousal at the time of the domestic violence. This inappropriate arousal may be reflected in altered heart rate regulation. If heart rate is systematically regulated by vagal mechanisms, then increases in heart rate should correlate with decreases in cardiac vagal activity, as indexed by respiratory sinus arrhythmia (RSA). We hypothesized that perpetrators of domestic violence have an alteration in heart rate regulation. To test this hypothesis we compared the results of a postural shift performed on perpetrators, healthy volunteers, and nonviolent alcoholics. Results showed there were no significant differences in heart rate, RSA, or catecholamines. However, the significant inverse relationship between posture-elicited changes in RSA and heart rate present in the healthy volunteers was not found in perpetrators. These differences in the covariation between heart rate and RSA may represent differences in the neural regulation of heart rate and may be related to difficulties in controlling autonomic state.

TT - Studio di coorte di mortalità degli addetti alla concia del cuoio e delle pelli nel territorio dell'azienda USL 11--Zona Valdarno Inferiore. AN - 71864812; 12087805 AB - Epidemiological studies of tanners have shown increased risk for a number of cancer sites, namely: lung, bladder, kidney and urinary organs as well as stomach, intestine, pancreas, nose and nasal cavities, together with leukemias and soft tissue sarcomas. To study cause specific mortality of leather tanners in Tuscany (Valdarno Inferiore area). The cohort included 4874 workers (4150 males and 724 females) employed in 92 tanneries operating in 1996 (Valdarno Inferiore Tanneries Census) which were also operating on 31-12-1970. Ascertainment of vital status was completed for all individuals on 31-12-1998 (end of follow-up), and the cause of death was known for all deceased subjects. Demographic and work history data were obtained from factory payrolls. Regional mortality rates were used for comparison to calculate SMR (Standardised Mortality Ratio) and 90% Confidence Intervals (CI). In addition to the overall cohort analysis, for men only separate analyses were completed for finishers, chrome tanners and vegetable tanners. The study showed an increased mortality from lung cancer among finishers, Standardised Mortality Ratio (SMR) 145, 19 observed (obs) (90% Confidence Intervals, 90% CI 95-212), from bladder cancer in the overall cohort (SMR 134, 9 obs, 90% CI 70-233) and among finishers (SMR 125, 2 obs, 90% CI 22-393) and from pancreatic cancer among finishers (SMR 120, 2 obs, 90% CI 21-379). Mortality from lymphoemopoietic cancer is above expected, and the increase is mainly due to myeloid leukaemia, both in males (SMR 208, 5 obs, 90% CI 82-437) and females (SMR 599, 2 obs, 90% CI 106-1887). No deaths from soft tissue sarcoma were observed. A new finding of the study was the increased mortality from cancer of the endocrine glands (SMR 566, 4 obs, 90% CI 194-1297), psychiatric disorders (SMR 195, 6 obs, 90% CI 85-385) and blood diseases (SMR 329, 4 obs, IC 90% 112-752). The observations of increased lung cancer mortality among finishers, of bladder cancer in the overall cohort and among finishers, as well as an increase in pancreatic cancer among the latter, confirm previous epidemiological findings among tanners. The increase in myeloid leukemia mortality for both males and females, and the absence of deaths from cancer of the connective tissue, which includes soft tissue sarcomas, are worthy of note. The results should be valued with caution, given the small number of cases and the novelty of some observations.

AN - 71842788; 12071535 AB - Naphthal-NU, 2-[2-[3-(2-chloroethyl)-3-nitrosoureido]ethyl]-1H-benz[de]isoquinoline-1,3-dione (Compound 1) has been synthesized as a rationally designed new mixed-function anticancer agent from 1,8-naphthalic anhydride. Its chemical alkylating activity compared with CCNU as standard compound indicated that it possesses greater alkylating activity than the latter. Its antitumour efficacy was assessed in vivo in two murine ascites tumours namely Sarcoma-180 (S-180) and Ehrlich ascites carcinoma (EAC) by measuring the increase in median survival times (MST) of drug treated (T) over untreated control (C) mice. Three clinical drugs namely CCNU (lomustine), endoxan (cyclophosphamide) and 5-fluorouracil (5-FU) were used as positive controls for comparison. Compound 1 has displayed excellent and reproducible antitumoural activity having curative effects in these tumours comparable with CCNU and 5-FU. It has also significantly increased the life span of mice bearing highly advanced tumour for 10 days before the drug challenge. Its toxicity was also assessed in vivo in normal and in S-180 bearing mice by measuring drug-induced changes in hematological parameters, femoral bone marrow and splenic cellularity sequentially on days 9, 15 and 21 following drug treatment at the optimum dose of 50 mg/kg from day 1 to 7. The results indicated that the compound did not adversely affect hematopoiesis. Drug-induced hepatotoxicity and nephrotoxicity were also evaluated at its optimum dose on those days but no such toxicities were detected. It was further screened in vitro in 6 different human tumour cell lines but no significant activity was observed in those lines.

N1 - Last updated - 2017-01-18 ER - TY - JOUR T1 - A quantitative approach for estimating exposure to pesticides in the Agricultural Health Study. AN - 71839728; 12074034 AB - We developed a quantitative method to estimate long-term chemical-specific pesticide exposures in a large prospective cohort study of more than 58000 pesticide applicators in North Carolina and Iowa. An enrollment questionnaire was administered to applicators to collect basic time- and intensity-related information on pesticide exposure such as mixing condition, duration and frequency of application, application methods and personal protective equipment used. In addition, a detailed take-home questionnaire was administered to collect further intensity-related exposure information such as maintenance or repair of mixing and application equipment, work practices and personal hygiene. More than 40% of the enrolled applicators responded to this detailed take-home questionnaire. Two algorithms were developed to identify applicators' exposure scenarios using information from the enrollment and take-home questionnaires separately in the calculation of subject-specific intensity of exposure score to individual pesticides. The 'general algorithm' used four basic variables (i.e. mixing status, application method, equipment repair status and personal protective equipment use) from the enrollment questionnaire and measurement data from the published pesticide exposure literature to calculate estimated intensity of exposure to individual pesticides for each applicator. The 'detailed' algorithm was based on variables in the general algorithm plus additional exposure information from the take-home questionnaire, including types of mixing system used (i.e. enclosed or open), having a tractor with enclosed cab and/or charcoal filter, frequency of washing equipment after application, frequency of replacing old gloves, personal hygiene and changing clothes after a spill. Weighting factors applied in both algorithms were estimated using measurement data from the published pesticide exposure literature and professional judgment. For each study subject, chemical-specific lifetime cumulative pesticide exposure levels were derived by combining intensity of pesticide exposure as calculated by the two algorithms independently and duration/frequency of pesticide use from the questionnaire. Distributions of duration, intensity and cumulative exposure levels of 2,4-D and chlorpyrifos are presented by state, gender, age group and applicator type (i.e. farmer or commercial applicator) for the entire enrollment cohort and for the sub-cohort of applicators who responded to the take-home questionnaire. The distribution patterns of all basic exposure indices (i.e. intensity, duration and cumulative exposure to 2,4-D and chlorpyrifos) by state, gender, age and applicator type were almost identical in two study populations, indicating that the take-home questionnaire sub-cohort of applicators is representative of the entire cohort in terms of exposure.

The Superfund Basic Research Program, administered by the National Institute of Environmental Health Sciences, an institute of the National Institutes of Health, is committed to providing the nation's decision makers with better tools to identify the routes and effects of exposure and develop innovative technologies to reduce exposures. In this article, we demonstrate how the program contributes to understanding the exposure disease link, highlight the cutting-edge and practical nature of this very fundamental research program and discuss its approach to addressing these problems. We also identify several broad themes that are likely to direct the program's future research endeavors.

AN - 71677153; 12005089 AB - To describe the safety and efficacy of voriconazole in children treated within the compassionate release program. Children received voriconazole on a compassionate basis for treatment of an invasive fungal infection if they were refractory to or intolerant of conventional antifungal therapy. Voriconazole was administered as a loading dose of 6 mg/kg every 12 h i.v. on Day 1 followed by 4 mg/kg every 12 h i.v. thereafter. When feasible the route of administration of voriconazole was changed from i.v. to oral (100 or 200 mg twice a day for patients weighing or = 40 kg, respectively). Outcome was assessed by investigators at the end of therapy or at the last visit as success (complete or partial response), stable infection, or failure, based on protocol-defined criteria. Sixty-nine children (ages 9 months to 15 years; median, 7 years) received voriconazole; 58 had a proven or probable fungal infection. Among these 58 patients 27 had hematologic malignancies and 13 had chronic granulomatous disease as the most frequent underlying conditions. Forty-two patients had aspergillosis, 8 had scedosporiosis, 4 had invasive candidiasis and 4 had other invasive fungal infections. The median duration of voriconazole therapy was 93 days. At the end of therapy 26 patients (45%) had a complete or partial response. Four patients (7%) had a stable response, 25 (43%) failed therapy and 4 (7%) were discontinued from voriconazole because of intolerance. Success rates were highest in patients with chronic granulomatous disease (62%) and lowest in patients with hematologic malignancies (33%). Two patients experienced treatment-related serious adverse events (ulcerated lips with rash, elevated hepatic transaminases or bilirubin). A total of 23 patients had voriconazole-related adverse events, 3 (13%) of which caused discontinuation of voriconazole therapy. The most commonly reported adverse events included elevation in hepatic transaminases or bilirubin (n = 8), skin rash (n = 8), abnormal vision (n = 3) and a photosensitivity reaction (n = 3). These data support the use of voriconazole for treatment of invasive fungal infections in pediatric patients who are intolerant of or refractory to conventional antifungal therapy.

AN - 71671169; 12004803 AB - Thousands of patients die annually from unresectable metastatic or primary hepatic cancers confined to liver. Isolated hepatic perfusion (IHP) is a regional treatment strategy in which the vascular supply to the liver is isolated and perfused with a therapeutic regimen using an extracorporeal circuit consisting of a reservoir, heat exchanger, and oxygenator. Drug doses that would cause severe toxicities if delivered systemically can be confined to the liver by isolated hepatic perfusion, resulting in the ability to intensify treatment to the cancer-burdened region of the body. Agents and mechanisms commonly used in IHP include melphaIan, hyperthermia, and tumor necrosis factor. IHP appears to be efficacious for patients with advanced disease, as reflected by large tumor size, high number of lesions, or significant overall tumor burden in the liver. In addition, responses are observed for patients whose cancer is refractory to systemic and hepatic arterial infusion chemotherapy. Recent clinical trials have demonstrated that IHP has anti-tumor efficacy against primary hepatic neoplasms and metastases from various primary tumors, such as colorectal carcinoma, ocular melanoma, and neuroendocrine tumors. Current studies demonstrate that combining hepatic arterial infusion with floxuridine after IHP for patients with colorectal cancer metastases is associated with significant and durable response rates. Continued clinical evaluation is warranted for the use of IHP in the treatment of unresectable liver metastases. JF - Cancer journal (Sudbury, Mass.)

AN - 71668669; 11984070 AB - Concurrent and pre-exposure of A431 human epidermoid cancer cells to UCN-01, an investigational anticancer drug, with 5-fluoro--2'-deoxyuridine (FdUrd), which targets thymidylate synthase, produced more than additive cytotoxicty. A 24-h exposure to 10 nM FdUrd led to inhibition of TS, a 2.5-fold increase in total thymidylate synthase protein content, profound dTTP depletion and a 6.3-fold increase in the ratio of dATP to dTTP, but did not cause single-strand breaks in DNA. However, FdUrd enhanced UCN-01-associated DNA strand breaks. Concurrent thymidine exposure led to repletion of dTTP pools, and cytoprotection against FdUrd alone and with UCN-01. UCN-01 arrested cells in G1, decreased the percentage of FdUrd-treated cells in S phase and reduced FdUrd-DNA incorporation, suggesting the latter was not important for cytotoxicity. Delayed induction of high molecular mass DNA fragmentation and poly(ADP-ribose) polymerase cleavage was observed with the combination of UCN-01 and FdUrd. These findings suggest that while FdUrd-mediated deoxynucleotide imbalance alone was insufficient to induce apoptosis in this p53-mutant cell line, it magnified UCN-01's effects, most likely by interfering with DNA repair. The clinical evaluation of UCN-01 combined with 5-fluoropyrimidines may be of interest.

AN - 71612099; 11959813 AB - Transforming growth factor-beta (TGF-beta) regulates proliferation, morphogenesis, and functional differentiation in the mammary gland and plays complex roles in mammary tumorigenesis. Here we show that the signaling mediators Smad1-Smad5 are expressed at all stages of mammary gland development. To begin to investigate which Smads mediate which TGF-beta responses, we have analyzed mammary gland development in Smad3 null mice. Smad3 null virgin females showed delayed mammary gland development. However, this phenotype was secondary to ovarian insufficiency because Smad3 null mammary epithelium developed normally in hormonally supplemented Smad3 null mice or when transplanted into wild-type hosts. Absence of Smad3 had no effect on the ability of TGF-beta to inhibit the growth of mammary epithelial cells in culture, and no compensatory changes in expression or activation of Smad2 were seen in the Smad3 null epithelium. A small but significant decrease in apoptotic cells was seen in involuting glands from Smad3 null transplants. The results suggest that epithelial Smad3 is dispensable for TGF-beta effects on proliferation and differentiation in the mammary gland, but that it contributes in a nonredundant manner to the induction of apoptosis.

AN - 71603167; 11950170 AB - Systemic hypoxemia, occurring in space-occupying lung pathologies such as inflammation and neoplasms. reduces the gas exchange area and stimulates catecholamine secretion from the adrenal medulla where chronic endocrine hyperactivity may lead to hyperplasia and neoplasia. We investigated the possible correlation between nonneoplastic chronic pulmonary lesions and adrenal pheochromocytoma in 9 recent, NTP, 2-year particulate inhalation studies in male F344 rats. Re-evaluation for chronic active inflammation, interstitial fibrosis, alveolar epithelial hyperplasia, squamous metaplasia, proteinosis, and histiocytosis revealed significant associations of pheochromocytoma only with the severity of inflammation and fibrosis. Nickel oxide, cobalt sulfate, indium phosphide, talc, and nickel subsulfide studies showed chemical-related incidences of adrenal pheochromocytoma and significant (p < 0.01) associations with inflammation and fibrosis. Gallium arsenide, vanadium pentoxide, molybdenum trioxide, and nickel sulfate hexahydrate studies revealed an increased incidence and/or severity of nonneoplastic lung lesions, but no increased incidence of pheochromocytoma. Although gallium arsenide and molybdenum trioxide showed no dose-related increase in pheochromocvtoma, a significant (p < 0.01) correlation of the latter with the severity of fibrosis and inflammation occurred. In the vanadium pentoxide and nickel sulfate hexahydrate studies, no relationship between nonneoplastic lung lesions and pheochromocytoma was manifested. Our investigation assessed the strength of these various associations and supports the possible roles of 2 chronic pulmonary lesions-fibrosis and inflammation-and hypoxemia in the induction of pheochromocytoma in the F344 male rat.

AN - 71597485; 11950161 AB - Elmiron, a highly sulfated, semisynthetic pentose polysaccharide with properties similar to heparin, is used for the treatment of interstitial cystitis. Thirteen-week gavage studies were conducted by administering the drug in deionized water to F344/N rats and B6C3F1 mice once daily, 5 days per week for up to 13 consecutive weeks, at doses of 0, 63, 125, 250, 500, and 1,000 mg/kg body weight. No significant drug-related effects were observed in body weight, survival, clinical, and necropsy results. Significant organ weight increases were seen in the liver, lungs, and spleen of both species and the kidneys of rats, mainly in groups treated with 250 mg/kg/day and above. Hematological analysis indicated increases for both species in the white blood cell and lymphocyte counts. Sites of toxicity identified histopathologically were the rectum, liver, mesenteric and mandibular lymph nodes (both sexes), spleen (mice only), and lungs and kidneys (rats only). Lesions consisted mainly of infiltration into multiple tissues of vacuolated histiocytes, which, by histochemical investigation, indicated the presence of neutral and acidic mucins and lipidic material within the vacuoles. Transmission electron microscopy identified these vacuoles as lysosomal structures that exhibited a variety of contents. On the basis of our findings, we propose that Elmiron was absorbed through the focally disrupted rectal mucosa, was deposited in the lamina propria, accumulated within macrophages, and then was distributed by these cells or as a free chemical via the lymphatics and blood, to the various organ sites manifesting histiocytic infiltration. The cytoplasmic membrane-bound structures within macrophages were lysosomes containing membranous material of cellular origin and, perhaps, remnants of the deposited test material, Elmiron.

AN - 71590703; 11950166 AB - Because sampling of the paired lobes (ventral, dorsal, lateral, and anterior) of the mouse prostate has often been inconsistent, comparisons among different investigations have lacked validity. The absence of site identification for prostatic lesions has made reported incidences relatively nonspecific. We present here the lobe-specific incidences and degree of severity of spontaneous lesions in prostate, coagulating gland (anterior prostatic lobe), seminal vesicles, and ampullary glands in 612 control B6C3F1 mice from 12 recent National Toxicology Program 2-year carcinogenicity and toxicity studies conducted in 1 of 4 different laboratories. Lymphocytic infiltration, inflammation, epithelial hyperplasia, mucinous cyst, and mucinous metaplasia were observed in the dorsolateral lobes. Lymphocytic infiltration, inflammation, epithelial hyperplasia, and edema were present in the ventral lobes. Lymphocytic infiltration, acinar dilatation, inflammation, epithelial hyperplasia, and atrophy occurred in the coagulating glands. No neoplastic lesions were observed in the prostate or coagulating gland. Lymphocytic infiltration, acinar dilatation, inflammation, atrophy, adenoma, adenocarcinoma, and a granular cell tumor were observed in the seminal vesicles. Lymphocytic infiltration was also present in the ampullary glands. The results of our survey indicate that the amounts of glandular tissues were not present consistently in slides from the different laboratories. Landmarks for uniform tissue trimming are needed. We therefore suggest an optimal trimming and embedding method for mouse prostate and seminal vesicles to ensure adequate, consistent sampling.

AN - 71577624; 11936822 AB - Non-Hodgkin's lymphoma (NHL) encompasses diverse subtypes, and analyzing NHL as a single outcome may mask associations. In a new approach we evaluated associations with subtypes defined by the t(14;18) translocation, reasoning that cases within these subtypes would have more common risk factors than all NHL combined. Archival biopsies from cases in a population-based NHL study were assayed for t(14;18) using polymerase chain reaction amplification. Exposures in 68 t(14;18)-positive and 114-negative cases were compared with 1245 controls. The expectation-maximization algorithm was used to fit polytomous regression models based on all available information, including data from 440 unclassified cases. Family history of hemolymphatic cancer was associated with t(14;18)-negative NHL (odds ratio (OR) 2.4, 95% confidence interval (CI) 1.4 3.9). but not t(14;18)-positive NHL. Cigarette smoking was weakly associated with t(14;18)-positive NHL (OR 1.7, CI 0.9-3.3), but ORs decreased as smoking increased. Chewing tobacco was associated with t(14;18)-positive NHL, particularly when used before age 18 (OR 2.5. CI 1.0-6.0, 13 exposed cases). Odds ratios for both case-subtypes were doubled among hair-dye users. Cigarette smoking was not clearly associated with t(14;18)-positive NHL. Family history may be a marker for factors that act specifically through t(14;18)-negative pathogenic mechanisms.

AN - 71568147; 11891201 AB - Susceptibility to lead toxicity in MT-null mice and cells, lacking the major forms of the metallothionein (MT) gene, was compared to wild-type (WT) mice or cells. Male MT-null and WT mice received lead in the drinking water (0 to 4000 ppm) for 10 to 20 weeks. Lead did not alter body weight in any group. Unlike WT mice, lead-treated MT-null mice showed dose-related nephromegaly. In addition, after lead exposure renal function was significantly diminished in MT-null mice in comparison to WT mice. MT-null mice accumulated less renal lead than WT mice and did not form lead inclusion bodies, which were present in the kidneys of WT mice. In gene array analysis, renal glutathione S-transferases were up-regulated after lead in MT-null mice only. In vitro studies on fibroblast cell lines derived from MT-null and WT mice showed that MT-null cells were much more sensitive to lead cytotoxicity. MT-null cells accumulated less lead and formed no inclusion bodies. The MT-null phenotype seems to preclude lead-induced inclusion body formation and increases lead toxicity at the organ and cellular level despite reducing lead accumulation. This study reveals important roles for MT in chronic lead toxicity, lead accumulation, and inclusion body formation.

AN - 71551649; 11911839 AB - A(3) adenosine receptor (A(3)AR) agonists have been reported to influence cell death and survival. The effects of an A(3)AR agonist, 1-[2-chloro-6-[[(3-iodophenyl)methyl]amino]-9H-purin-9-yl]-1-deoxy-N-methyl-beta-D-ribofuranonamide (Cl-IB-MECA), on apoptosis in two human leukemia cell lines, HL-60 and MOLT-4, were investigated. Cl-IB-MECA (> or =30 microM) increased the apoptotic fractions, as determined using fluorescence-activated cell sorting (FACS) analysis, and activated caspase 3 and poly-ADP-ribose-polymerase. Known messengers coupled to A(3)AR (phospholipase C and intracellular calcium) did not seem to play a role in the induction of apoptosis. Neither dantrolene nor BAPTA-AM affected the Cl-IB-MECA-induced apoptosis. Cl-IB-MECA failed to activate phospholipase C in HL-60 cells, while UTP activated it through endogenous P2Y(2) receptors. Induction of apoptosis during a 48hr exposure to Cl-IB-MECA was not prevented by the A(3)AR antagonists [5-propyl-2-ethyl-4-propyl-3-(ethylsulfanylcarbonyl)-6-phenylpyridine-5-carboxylate] (MRS 1220) or N-[9-chloro-2-(2-furanyl)[1,2,4]triazolo[1,5-c]quinazolin-5-yl]benzeneacetamide (MRS 1523). Furthermore, higher concentrations of MRS 1220, which would also antagonize A(1) and A(2A) receptors, were ineffective in preventing the apoptosis. Although Cl-IB-MECA has been shown in other systems to cause apoptosis through an A(3)AR-mediated mechanism, in these cells it appeared to be an adenosine receptor-independent effect, which required prolonged incubation. In both HL-60 and MOLT-4 cells, Cl-IB-MECA induced the expression of Fas, a death receptor. This induction of Fas was not dependent upon p53, because p53 is not expressed in an active form in either HL-60 or MOLT-4 cells. Cl-IB-MECA-induced apoptosis in HL-60 cells was augmented by an agonistic Fas antibody, CH-11, and this increase was suppressed by the antagonistic anti-Fas antibody ZB-4. Therefore, Cl-IB-MECA induced apoptosis via a novel, p53-independent up-regulation of Fas.

AN - 71549056; 11920964 AB - Health effects of pesticides have not been well studied in black farmers. We describe agricultural practices and pesticide-related symptoms in North Carolina black and white farmers participating in the Agricultural Health Study. Self-administered questionnaires were completed by 891 black and 11,909 white farmers licensed to apply restricted pesticides. Regression models were used to compare characteristics by race. Black farmers reported lower lifetime pesticide use, less use of each class of pesticides (e.g., herbicides, insecticides), less use of high exposure application methods, and fewer pesticide-related symptoms such as headaches or dizziness, skin irritation, chest discomfort and feeling nervous or depressed than did white farmers. Differences between black and white farmers may be explained by farm characteristics or economics. Despite lower use of pesticides, black farmers may have other work practices that affect exposure and risk.

AN - 71542278; 11911027 AB - Using data from the 1960 and 1970 Swedish censuses and the Swedish Cancer Register for 1971 to 1989, this study investigated variations in cancer risk by gender associated with employment in painting trades and paint manufacturing. Among men, standardized incidence ratios were significantly increased for lung cancer among painters and lacquerers; bladder cancer among artists; and pancreas cancer, lung cancer, and nonlymphocytic leukemia among paint and varnish plant workers. Risks for women were elevated for cancers of the esophagus, larynx, and oral cavity among lacquerers and for oral cancer among glaziers. These findings are consistent with the report of the International Agency for Research on Cancer that classified painting as an occupationally related cause of cancer and provide further evidence that the risk of certain cancers is increased by exposures in the paint manufacturing process.

AN - 71541655; 11880504 AB - Recent epidemiological and clinical data suggest that persons with low folic acid levels and elevated homocysteine levels are at increased risk of Alzheimer's disease (AD), but the underlying mechanism is unknown. We tested the hypothesis that impaired one-carbon metabolism resulting from folic acid deficiency and high homocysteine levels promotes accumulation of DNA damage and sensitizes neurons to amyloid beta-peptide (Abeta) toxicity. Incubation of hippocampal cultures in folic acid-deficient medium or in the presence of methotrexate (an inhibitor of folic acid metabolism) or homocysteine induced cell death and rendered neurons vulnerable to death induced by Abeta. Methyl donor deficiency caused uracil misincorporation and DNA damage and greatly potentiated Abeta toxicity as the result of reduced repair of Abeta-induced oxidative modification of DNA bases. When maintained on a folic acid-deficient diet, amyloid precursor protein (APP) mutant transgenic mice, but not wild-type mice, exhibited increased cellular DNA damage and hippocampal neurodegeneration. Levels of Abeta were unchanged in the brains of folate-deficient APP mutant mice. Our data suggest that folic acid deficiency and homocysteine impair DNA repair in neurons, which sensitizes them to oxidative damage induced by Abeta.

AN - 71537249; 11916555 AB - 5-Fluorouracil (5-FU) and 5'-deoxy-5-fluorouridine (5'-DFUR), a prodrug of 5-FU, are representative of the chemotherapeutic agents for colorectal adenocarcinomas. Pyrimidine nucleoside phosphorylase (PyNPase) catalyses the conversion of 5'-DFUR to 5-FU, the activated form. Murine adenocarcinoma CT26 cells were transfected with human PyNPase cDNA. The engineered transfectants producing PyNPase augmented the response to 5'-DFUR in vitro and in vivo. Animals were administered by means of intraperitoneal (i.p.) injection, and not orally, in order to obtain a better efficiency of absorption. The tumours of the transfected cells nearly all disappeared, even following treatment with quite a small amount of the anticancer agent. The animals injected with the tranfected cells were protected against subsequent challenge with the parental tumour cell line. These findings demonstrate that PyNPase gene transfection increases the sensitivity to 5'-DFUR, and thereby decreases the toxicity of the agent.

AN - 71534506; 11861804 AB - The insulinotropic hormone glucagon-like peptide-1 (7-36)-amide (GLP-1) has potent effects on glucose-dependent insulin secretion, insulin gene expression, and pancreatic islet cell formation and is presently in clinical trials as a therapy for type 2 diabetes mellitus. We report on the effects of GLP-1 and two of its long-acting analogs, exendin-4 and exendin-4 WOT, on neuronal proliferation and differentiation, and on the metabolism of two neuronal proteins in the rat pheochromocytoma (PC12) cell line, which has been shown to express the GLP-1 receptor. We observed that GLP-1 and exendin-4 induced neurite outgrowth in a manner similar to nerve growth factor (NGF), which was reversed by coincubation with the selective GLP-1 receptor antagonist exendin (9-39). Furthermore, exendin-4 could promote NGF-initiated differentiation and may rescue degenerating cells after NGF-mediated withdrawal. These effects were induced in the absence of cellular dysfunction and toxicity as quantitatively measured by 3-(4,5-cimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide and lactate dehydrogenase assays, respectively. Our findings suggest that such peptides may be used in reversing or halting the neurodegenerative process observed in neurodegenerative diseases, such as the peripheral neuropathy associated with type 2 diabetes mellitus and Alzheimer's and Parkinson's diseases. Due to its novel twin action, GLP-1 and exendin-4 have therapeutic potential for the treatment of diabetic peripheral neuropathy and these central nervous system disorders.

AN - 71523255; 11897984 AB - A clinical model is needed to compare inhaled corticosteroids (ICSs) with respect to efficacy. The purpose of this investigation was to compare the relative beneficial and systemic effects in a dose-response relationship for 2 ICSs. A 24-week, parallel, open-label, multicenter trial examined the benefit-risk ratio of 2 ICSs in persistent asthma. Benefit was assessed by improvements in FEV(1) and PC(20); risk was assessed by overnight plasma cortisol suppression. Thirty subjects were randomized to either beclomethasone dipropionate (BDP) 168, 672, and 1344 microg/day (n = 15) or fluticasone propionate (FP) 88, 352, and 704 microg/day (n = 15), both administered by means of a metered dose inhaler (MDI) with chlorofluorocarbon propellant via a spacer, in 3 consecutive 6-week intervals; this was followed by 3 weeks of FP dry powder inhaler (DPI) 2000 microg/day. Maximum FEV(1) response occurred with the low dose for FP-MDI and the medium dose for BDP-MDI and was not further increased by treatment with FP-DPI. Near-maximum methacholine PC(20) improvement occurred with the low dose for FP-MDI and the medium dose for BDP-MDI. Both BDP-MDI and FP-MDI caused dose-dependent cortisol suppression. Responsiveness to ICS treatment was found to vary markedly among subjects. Good (>15%) FEV(1) response, in contrast to poor (3 doubling dilutions) improvement in PC(20), in contrast to poor (<1 doubling dilution) improvement, was found to be associated with high sputum eosinophil levels (3.4% vs 0.1%) and older age at onset of asthma (age, 20-29 years vs <10 years). Near-maximal FEV(1) and PC(20) effects occurred with low-medium dose for both ICSs in the subjects studied. High-dose ICS therapy did not significantly increase the efficacy measures that were evaluated, but it did increase the systemic effect measure, overnight cortisol secretion. Significant intersubject variability in response occurred with both ICSs. It is possible that higher doses of ICSs are necessary to manage more severe patients or to achieve goals of therapy not evaluated in this study, such as prevention of asthma exacerbations.

AN - 71519574; 11890330 AB - Multivariate current status data, consist of indicators of whether each of several events occur by the time of a single examination. Our interest focuses on inferences about the joint distribution of the event times. Conventional methods for analysis of multiple event-time data cannot be used because all of the event times are censored and censoring may be informative. Within a given subject, we account for correlated event times through a subject-specific latent variable, conditional upon which the various events are assumed to occur independently. We also assume that each event contributes independently to the hazard of censoring. Nonparametric step functions are used to characterize the baseline distributions of the different event times and of the examination times. Covariate and subject-specific effects are incorporated through generalized linear models. A Markov chain Monte Carlo algorithm is described for estimation of the posterior distributions of the unknowns. The methods are illustrated through application to multiple tumor site data from an animal carcinogenicity study.

AN - 71518180; 11895857 AB - Dietary phenolic substances including resveratrol, a stillbene compound, are found in several fruits and vegetables, and these compounds have been reported to have anti-oxidant, anti-inflammatory and antitumorigenic activities. However, the molecular mechanisms underlying the antitumorigenic or chemopreventive activities of these compounds remain largely unknown. The expression of NAG-1 [non-steroidal anti-inflammatory (NSAID) drug-activated gene-1], a member of the transforming growth factor-beta (TGF-beta) superfamily, has been shown to be associated with pro-apoptotic and antitumorigenic activities. Here, we have demonstrated that resveratrol induces NAG-1 expression and apoptosis in a concentration-dependent manner. Resveratrol increases the expression of p53, tumor suppressor protein, prior to NAG-1 induction, indicating that NAG-1 expression by resveratrol is mediated by p53 expression. We also show that the p53 binding sites within the promoter region of NAG-1 play a pivotal role to control NAG-1 expression by resveratrol. Derivatives of resveratrol were examined for NAG-1 induction, and the data suggest that resveratrol-induced NAG-1 and p53 induction is not dependent on its anti-oxidant activity. The data may provide linkage between p53, NAG-1 and resveratrol, and in part, a new clue to the molecular mechanism of the antitumorigenic activity of natural polyphenolic compounds.

AN - 71516980; 11889200 AB - Exendin-4 is a potent and long-acting agonist of the glucagon-like peptide-1 (GLP-1) receptor. GLP-1 is an insulinotropic gut peptide and is being evaluated for the regulation of plasma glucose in type 2 diabetes. The purpose of the present study was to ascertain whether exendin-4 is insulinotropic and whether it has long-lived biological effects in nondiabetic and type 2 diabetic subjects. Because incretins are glucose dependent with respect to their insulin-releasing capacity, we used the hyperglycemic glucose clamp technique to begin to address these issues in two separate protocols. In one protocol, we infused exendin-4 (0.15 pmol x kg(-1) x min(-1)) in seven nondiabetic and seven type 2 diabetic subjects during the second hour of a 5-h hyperglycemic clamp in which fasting plasma glucose was raised by 5.4 mmol/liter. The second protocol was identical to the first except that plasma glucose was allowed to fall to the fasting levels during the fourth hour and again raised by 5.4 mmol/liter during the fifth hour in four nondiabetic and four diabetic subjects. With the initiation of exendin-4 infusion at 60 min, plasma insulin response was potentiated 4- to 5-fold in both groups. Despite termination of exendin-4 at the end of the second hour, the insulin levels remained elevated for several hours and hyperglycemia was maintained. All volunteers ate a meal 5.5 h after inducing hyperglycemia. Postprandial plasma glucose, insulin, and GLP-1 did not rise in any subject, possibly because of delayed gastric emptying by exendin-4 even though its infusion had been terminated 4 h previously. We concluded that exendin-4 is a potent and long-lasting insulinotropic agent in nondiabetic and diabetic subjects.

AN - 71516546; 11888916 AB - Bad, a proapoptotic member of the Bcl-2 family, is inactivated by phosphorylation, and this loss of activity may contribute to the malignancy of certain types of tumors such as glioblastoma and prostate cancer. To determine whether extracellular Bad can be delivered into cells via cell surface receptor binding and induce apoptosis, we genetically fused the mouse Bad gene to the gene for the translocation and receptor-binding domains of diphtheria toxin (DTTR). The purified Bad (wild-type)-DTTR protein showed cytotoxicity to human glioma cells in a dose-dependent manner. Bad phosphorylation sites at codons 112 and 136 were mutated from serine to alanine to prevent Bad inactivation by kinases and to increase the toxicity of Bad. The Bad (S112A S136A)-DTTR protein was at least 5 times more toxic than Bad (wild-type)-DTTR with an IC(50) of 5 x 10(-8) M. The Bad (S112A S136A)-DTTR protein altered the subcellular distribution of Bcl-X(L), indicating that it enters the cell cytoplasm and binds Bcl-X(L). Bad (S112D S136A)-DTTR, mutated to mimic phosphorylation of Bad, showed lower toxicity than either Bad (wild-type)-DTTR or Bad (S112A S136A)-DTTR, additionally indicating that Bad-DTTR must bind Bcl-X(L) to stimulate apoptosis. We conclude that extracellular Bad can be delivered into cells via the transport domain of a bacterial toxin and may be used to induce apoptosis.

AN - 71514485; 11891202 AB - Transforming growth factor-beta (TGF-beta) plays a central role in the pathogenesis of inflammatory and fibrotic diseases, including radiation-induced fibrosis. We previously reported that mice null for Smad3, a key downstream mediator of TGF-beta, show accelerated healing of cutaneous incisional wounds with reduced inflammation and accumulation of matrix. To determine if loss of Smad3 decreases radiation-induced injury, skin of Smad3+/+ [wild-type (WT)] and -/- [knockout (KO)] mice was exposed to a single dose of 30 to 50 Gy of gamma-irradiation. Six weeks later, skin from KO mice showed significantly less epidermal acanthosis and dermal influx of mast cells, macrophages, and neutrophils than skin from WT littermates. Skin from irradiated KO mice exhibited less immunoreactive TGF-beta and fewer myofibroblasts, suggesting that these mice will have a significantly reduced fibrotic response. Although irradiation induced no change in the immunohistochemical expression of the TGF-beta type I receptor, the epidermal expression of the type II receptor was lost after irradiation whereas its dermal expression remained high. Primary keratinocytes and dermal fibroblasts prepared from WT and KO mice showed similar survival when irradiated, as did mice exposed to whole-body irradiation. These results suggest that inhibition of Smad3 might decrease tissue damage and reduce fibrosis after exposure to ionizing irradiation.

Last updated - 2017-01-18 ER - TY - JOUR T1 - Hes-1, a known transcriptional repressor, acts as a transcriptional activator for the human acid alpha-glucosidase gene in human fibroblast cells. AN - 71513439; 11855828 AB - Hes-1, the mammalian homologue 1 of Drosophila hairy and Enhancer of split proteins, belongs to a family of basic helix-loop-helix proteins that are essential to neurogenesis, myogenesis, hematopoiesis, and sex determination. Hes-1 is a transcriptional repressor for a number of known genes including the human acid alpha-glucosidase (GAA) gene as we have previously shown in Hep G2 cells. The human GAA gene encodes the enzyme for glycogen breakdown in lysosomes, deficiency of which results in Glycogen Storage Disease type II (Pompe syndrome). Using constructs containing the DNA element that demonstrates repressive activity in Hep G2 cells and conditions in which the same transcription factors, Hes-1 and YY1, bind, we have shown that this element functions as an enhancer in human fibroblasts. Site-directed mutagenesis and overexpression of Hes-1 showed that Hes-1 functions as a transcriptional activator. The dual function of Hes-1 we have found is likely to contribute to the subtle tissue-specific control of this housekeeping gene. ©2002 Elsevier Science (USA).

AN - 71510621; 11890313 AB - We are interested in finding a dose that has a prespecified toxicity rate in the target population. In this article, we investigate five estimators of the target dose to be used with the up-and-down biased coin design (BCD) introduced by Durham and Flournoy (1994, Statistical Decision Theory and Related Topics). These estimators are derived using maximum likelihood, weighted least squares, sample averages, and isotonic regression. A linearly interpolated isotonic regression estimate is shown to be simple to derive and to perform as well as or better than the other target dose estimators in terms of mean square error and average number of subjects needed for convergence in most scenarios studied.

AN - 71507475; 11888904 AB - Breast cancer is one of the major causes of mortality among women in the United States. Although the causes of breast cancer remain unclear, it has been speculated that DNA base damage may lead to mutations that subsequently can be carcinogenic. Recently, defective oxidative DNA damage repair has been implicated in breast tumorigenesis. The major oxidative DNA lesion, 8-hydroxyguanine (8-oxoG), is increased in breast cancer, suggesting that this lesion may play a crucial role in the etiology of breast cancer. However, it is not known whether the repair of 8-oxoG or other oxidative base lesions is altered during breast carcinogenesis. We examined the ability of nuclear and mitochondrial extracts of two human breast cancer cell lines, MCF-7 and MDA-MB-468, to repair 8-oxoG lesion. We report that mitochondrial extracts from the two breast cancer cell lines are defective in the base excision repair of 8-oxoG relative to two noncancer cell lines. We also show that the incision activity of 8-oxoG was significantly lower in mitochondrial than in nuclear extracts in the breast cancer cell lines. The defective mitochondrial repair activity was not attributable to lower levels of human 8-hydroxyguanine DNA glycosylase, the base excision repair enzyme known to incise 8-oxoG in DNA. The repair of thymine glycol, another major oxidative DNA base lesion that blocks transcription and causes cell death, was similar in cancer and noncancer cells. Furthermore, nuclear extracts incised thymine glycol with a much higher efficiency than 8-oxoG. These data provide evidence for defective repair of 8-oxoG in mitochondria of MCF-7 and MDA-MB-468 breast cancer cell lines.

A phase II study of the EORTC Soft Tissue and Bone Sarcoma Group. AN - 71501509; 11872349 AB - Gemcitabine (2'-deoxy-2'-difluorocytidine monohydrochloride) at a dose of 1250 mg/m(2) was given as a 30-min intravenous (i.v.) infusion on days 1 and 8 in a 3-weekly schedule to 32 patients with advanced soft-tissue sarcoma (STS) failing first-line chemotherapy. One patient was ineligible due to a delay between the previous chemotherapy and the start of treatment. Of the eligible patients, median age was 53 years (range 23-73 years). The predominant histological subtype was leiomyosarcoma in 12 patients (38%). The median number of cycles was three (range 1-8 cycles) with a median total dose of gemcitabine of 6.25 g/m(2) (range 1.25-19.97 g/m(2)). The relative dose intensity of gemcitabine was 96% (range 50-103%). Treatment was tolerated very well with non-complicated haematological toxicity as the most frequently observed side-effect. Only one partial tumour response was documented, giving a response rate of 3.23% (95% Confidence Interval (CI): 0.08-16.2%). The median overall survival was 268 days (95% CI: 129-377) and the median time to progression was 45 days (95% CI: 41-79). These results indicate that gemcitabine given at this dose and schedule is not active as second-line therapy in advanced STS.

AN - 71500328; 11880480 AB - Striatal spiny projection neurons control basal ganglia outputs via action potential bursts conveyed to the globus pallidus and substantia nigra. Accordingly, burst activity in these neurons contributes importantly to basal ganglia function and dysfunction. These bursts are driven by multiple corticostriatal inputs that depolarize spiny projection neurons from their resting potential of approximately -85 mV, which is the down-state, to a subthreshold up-state of -55 mV. To understand dendritic processing of bursts during up-states, changes in intracellular calcium concentration ([Ca2+]i) were measured in striatal spiny projection neurons from cortex-striatum-substantia nigra organotypic cultures grown for 5-6 weeks using somatic whole-cell patch recording and Fura-2. During up-states, [Ca2+]i transients at soma and primary, secondary, and tertiary dendrites were highly correlated with burst strength (i.e., the number of spontaneous action potentials). During down-states, the action potentials evoked by somatic current pulses elicited [Ca2+]i transients in higher-order dendrites that were also correlated with burst strength. Evoked bursts during up-states increased dendritic [Ca2+]i transients supralinearly by >200% compared with the down-state. In the presence of tetrodotoxin, burst-like voltage commands failed to elicit [Ca2+]i transients at higher-order dendrites. Thus, dendritic [Ca2+]i transients in spiny projection neurons encode somatic bursts supralinearly during up-states through active propagation of action potentials along dendrites. We suggest that this conveys information about the contribution of a spiny projection neuron to a basal ganglia output specifically back to the corticostriatal synapses involved in generating these outputs.

AN - 71495957; 11875368 AB - High red meat intake has been linked with an increased risk of colorectal cancer and adenomas. During high temperature cooking of red meats, heterocyclic amines (HCAs) are generated; however, to be carcinogenic, they must be metabolized by enzymes including cytochrome P450 1A2 (CYP1A2) and N-acetyltransferase 1 (NAT1) and/or N-acetyltransferase 2 (NAT2). We have conducted a clinic-based case-control study of colorectal adenomas that focused on assessment of exposure to HCAs (estimated by use of a HCA database and meat cooking module) and modification of these exposures by genetic factors. We have previously reported that intake of MeIQx was associated with an increased risk of colorectal adenomas [overall association at 80th percentile, > 27.00 ng/day: odds ratio (OR) = 2.68, 95% confidence interval (CI) 1.58-4.55]. Here, we report our evaluation of whether variation in CYP1A2, NAT1 and/or NAT2 modify the association between HCAs and colorectal adenoma formation in 146 cases and 228 frequency-matched controls. The NAT1*10 allele was associated with a nonsignificant increased risk of colorectal adenomas (OR = 1.43; 95% CI 0.86-2.36). Further, when we analysed 2-amino-3,8-dimethylimidazo[4,5-f]quinoxaline (MeIQx) intake as a categorical variable, we observed a six-fold increase in adenoma risk among rapid NAT1 acetylators who consumed more than 27 ng a day (OR = 6.50; 95% CI 2.16-19.7), whereas among slow NAT1 acetylators, the increase in risk was two-fold (OR = 2.32; 95% CI 1.12-4.81). While suggestive, the results were not significantly different from each other on either an additive or multiplicative scale. In contrast, NAT2 genotype and CYP1A2 and NAT2 hepatic activity measured by caffeine urinary metabolites were not associated with adenoma risk, although an increase in risk with rapid CYP1A2 activity could not be ruled out (OR = 1.46; 95% CI 0.76-2.81). Moreover, there was no evidence that the effect of MeIQx was enhanced among subjects in any subgroup defined by variation in these measures. These results are compatible with the hypothesis that high HCA exposure is associated with an increased risk of colorectal adenomas, particularly in genetically susceptible subgroups. Further study of larger populations is needed to confirm and extend these observations.

AN - 71493337; 11880711 AB - Approximately one third of all patients with nonsmall cell lung cancer (NSCLC) are over the age of seventy. Elderly patients tolerate chemotherapy poorly because of impaired organ function and comorbidities. For this reason, these patients are often not considered eligible for aggressive cisplatin-based chemotherapy. A multidimensional geriatric evaluation is important to plan appropriate treatments. At present, there are no indications for adjuvant and neoadjuvant chemotherapy. Combined chemoradiotherapy in locally advanced disease increases toxicity and seems determine no survival advantage as compared with radiation therapy alone. In advanced disease, single-agent vinorelbine proves to be active and well-tolerated, and compared with best supportive care, improves survival and perhaps quality of life. Gemcitabine is active and also well tolerated. Taxanes are in advanced phase of evaluation. A phase III randomized trial showed that polychemotherapy with gemcitabine and vinorelbine does not improve any outcome as compared with single-agent chemotherapy with vinorelbine or gemcitabine. In clinical practice, single-agent chemotherapy should remain the standard treatment. The choice of the drug should be based on the toxicity profile of each drug and type of comorbid conditions. In the near future, new therapeutic strategies and biologic agents could improve present results.

AN - 71493016; 11867678 AB - Leukotriene B(4) (LTB(4)) is an easily diffusible proinflammatory chemotactic factor that has been posited to prime the initial inflammatory response for the action of other mediators, including C5a. 5-Lipoxygenase-deficient (5LX(-/-)) and C5-deficient mice only generated about 50% as much peritoneal leukocytosis as wild-type mice following intraperitoneal (IP) challenge with the sterile irritant, thioglycollate (P<0.005). Pretreatment of C5- mice with the specific 5-lipoxygenase inhibitor, zileuton, reduced peritoneal leukocytosis to almost unstimulated levels, suggesting that LTB(4) can act independently of C5a. Previously, LTB(4) and C5a have been shown in vitro to be inactivated by metabolites of superoxide. In the current study, we examined the fate of LTB(4) in the p47(phox-/-) mouse model of chronic granulomatous disease (CGD) in which the phagocyte NADPH oxidase is unable to produce superoxide. p47(phox-/-) mice generated more thioglycollate-elicited peritoneal leukocytosis than wild-type mice. Pretreatment with zileuton caused a 76% reduction in peritoneal leukocytosis in p47(phox-/-) mice (P<0.005) and a 54% reduction in wild-type mice (P<0.05), whereas pretreatment with dexamethasone or toradol (a cyclooxygenase inhibitor) had no effect. Following IP LTB(4) (1 microg/mouse), total recovered peritoneal LTB(4) was similar between p47(phox-/-) and wild-type mice at 10 and 30 min, but was approximately fivefold greater in p47(phox-/-) mice at 180 min. These data suggest that LTB(4) and C5a have separate but overlapping roles in thioglycollate-elicited peritonitis, and at least the leukotriene component is, in turn, regulated by reactive oxidants.

AN - 71491463; 11874984 AB - The chemokine and HIV receptor CXCR4 has been shown to play a role in chemotaxis and HIV-1 entry into T cells. Dibutyryl cAMP (DcAMP), an analog of cAMP, has been shown to increase CXCR4 cell surface expression and HIV-1 infectivity, but the molecular mechanism(s) responsible is unknown. Here we show that DcAMP treatment of purified human T lymphocytes increased transcription of CXCR4 mRNA as well as cell surface and intracellular CXCR4 protein expression. DcAMP-mediated stimulation of human PBL increased T-trophic HIV-1 (X4) fusion and viral replication as measured by syncytia formation and p24 levels, respectively. To determine the region(s) of the CXCR4 promoter required for cAMP responsiveness, truncations and point mutations of the CXCR4 promoter (nucleotides -1098 to +59) fused to luciferase were constructed and transiently transfected into human PBL. Deletional analysis demonstrated that the -1098 to -93 region of the CXCR4 promoter construct could be eliminated; the residual (-93 to +59) promoter retained cAMP responsiveness. Site-directed mutagenesis of a putative cAMP-responsive element (CRE) in the 5' UTR (+41 to +49) significantly and specifically attenuated the ability of DcAMP to drive the minimal CXCR4 promoter. Electrophoretic mobility shift assays demonstrated the formation of a complex between the CREB transcription factor and the putative CXCR4 CRE site. Our findings demonstrate a CRE element within the CXCR4 promoter that regulates CXCR4 transcription in response to changes in cAMP signaling.

AN - 71484148; 11861973 AB - A single dose of dioxin (2,3,7,8-tetrachlorodibenzo-p-dioxin or TCDD; 5 microg/kg, ip) inhibits 17beta-estradiol (E2)-induced uterine epithelial mitogenesis, apparently through disruption of stromal-epithelial interactions. To understand if TCDD alters early uterine (Ut) responses to E2, young adult C57BL/6J mice were ovariectomized and given (i.p.) either oil or 5 microg/kg TCDD. After 24 h, TCDD-treated mice received E2, and oil-treated mice were given E2 or oil. Body and Ut weights were collected 6 and 18 h later. Ut were flash-frozen at 6 h. E2 increased Ut weight (p < 0.0001) and Ut/body weight ratio (p < 0.0001), compared to mice given oil alone. Ut cyclin expression was assessed by an RNase protection assay. E2 increased mRNA expression for cyclin A2 and B1 (p < 0.05), in addition to D1, D2, and D3 (p < 0.001), while cyclin C was unchanged from oil controls and cyclins A1 and B2 were undetectable. In contrast, TCDD completely abolished E2-induced cyclin A2, which has been associated with S phase initiation, and reduced B1 and D2 (p < 0.05). Interestingly, TCDD did not alter E2-induced Ut weight increases at 6 h, but inhibited E2-induced Ut weight gain at 18 h. A 10-microg/kg TCDD dose was necessary for attenuation of the early E2-induced Ut weight increases (p < 0.01). Since TGF-beta regulates cyclins, Ut TGF-beta was also assessed in TCDD + E2-treated and control mice. TGF-beta mRNA levels were increased after TCDD compared to E2 alone (p < 0.01), suggesting a possible mechanism for TCDD inhibition of Ut cyclin A2. Thus, TCDD alters specific E2-regulated Ut G(1) phase activities and may inhibit E2-induced Ut epithelial mitogenesis by disrupting specific cell signaling mechanisms necessary for S phase initiation in vivo.

Essential involvement of the amino terminus of circumsporozoite protein. AN - 71483816; 11751898 AB - Plasmodium sporozoites display circumsporozoite (CS) protein on their surface, which is involved in the attachment of sporozoites to liver cells. CS protein is a member of the thrombospondin type I repeat (TSR) domain family and possess a single copy of TSR domain toward its carboxyl terminus. We show by a direct measurement the correlation between the binding activity of various segments of the CS protein and their ability to inhibit the invasion of liver cells by the sporozoites. We made eight truncated versions of Plasmodium falciparum CS protein to elucidate the role of various regions in the binding and invasion process. Deletion of the TSR domain actually enhanced binding activity by 2-3-fold without the loss of receptor specificity, indicating that TSR may not be the only domain in defining the specificity of binding. These same deletions blocked invasion of live sporozoites more efficiently than proteins that include the TSR domain. Deletion of as little as six amino acids from amino terminus of the protein, however, renders it incapable of binding to liver cells and as an inhibitor of sporozoite invasion. Hence, the binding of CS protein to liver cells and its ability to inhibit the invasion process are affected in a parallel manner, both positively and negatively, by sequence changes in the encoded CS gene. This indicates that both assays are measuring interrelated phenomenon and points to the essential involvement for the amino-terminal portion of the CS protein in these processes.

AN - 71479419; 11870259 AB - The objective of this article is to review data from studies that used a reinstatement model in rats to elucidate the neural mechanisms underlying relapse to heroin and cocaine seeking induced by exposure to the self-administered drug (drug priming), conditioned drug cues, and stressors. These factors were reported to contribute to relapse to drug use in humans following prolonged abstinence periods. In the reinstatement model, the ability of acute exposure to drug or nondrug stimuli to reinstate drug seeking is determined following training for drug self-administration and subsequent extinction of the drug-reinforced behavior. We will review studies in which pharmacological agents were injected systemically or intracranially to block (or mimic) reinstatement by drug priming, drug cues, and stressors. We also will review studies in which brain lesions, in vivo microdialysis and electrochemistry, and gene expression methods were used to map brain sites involved in relapse to drug seeking. Subsequently, we will discuss theoretical issues related to the processes underlying relapse to drugs and address methodological issues in studies on reinstatement of drug seeking. Finally, the implications of the findings from the studies reviewed for addiction theories and treatment will be discussed. The main conclusion of this review is that the neuronal mechanisms involved in relapse to heroin and cocaine seeking induced by drug priming, drug cues, and stressors are to a large degree dissociable. The data reviewed also suggest that the neuronal events mediating drug-induced reinstatement are to some degree dissociable from those mediating drug reinforcement.

AN - 71478332; 11751866 AB - Ba(2+) current through the L-type Ca(2+) channel inactivates essentially by voltage-dependent mechanisms with fast and slow kinetics. Here we found that slow inactivation is mediated by an annular determinant composed of hydrophobic amino acids located near the cytoplasmic ends of transmembrane segments S6 of each repeat of the alpha(1C) subunit. We have determined the molecular requirements that completely obstruct slow inactivation. Critical interventions include simultaneous substitution of A752T in IIS6, V1165T in IIIS6, and I1475T in IVS6, each preventing in additive manner a considerable fraction of Ba(2+) current from inactivation. In addition, it requires the S405I mutation in segment IS6. The fractional inhibition of slow inactivation in tested mutants caused an acceleration of fast inactivation, suggesting that fast and slow inactivation mechanisms are linked. The channel lacking slow inactivation showed approximately 45% of the sustained Ba(2+) or Ca(2+) current with no indication of decay. The remaining fraction of the current was inactivated with a single-exponential decay (pi(f) approximately 10 ms), completely recovered from inactivation within 100 ms and did not exhibit Ca(2+)-dependent inactivation properties. No voltage-dependent characteristics were significantly changed, consistent with the C-type inactivation model suggesting constriction of the pore as the main mechanism possibly targeted by Ca(2+) sensors of inactivation.

AN - 71477599; 11859107 AB - Despite the effects of glucocorticoids on immune function, relatively little is known about glucocorticoid-inducible genes and how their products may regulate lymphocyte function. Using DNA microarray technology to analyze gene expression in PBMC from healthy donors, we identified IL-7Ralpha as a glucocorticoid-inducible gene. This observation was confirmed at the mRNA and protein levels. Conversely, TCR signaling decreased IL-7Ralpha expression, and the relative strength of signaling between these two receptors determined the final IL-7Ralpha levels. The up-regulation of IL-7Ralpha by glucocorticoids was associated with enhanced IL-7-mediated signaling and function. Moreover, IL-7-mediated inhibition of apoptosis at increasing concentrations of glucocorticoids is consistent with enhanced cell sensitivity to IL-7 following glucocorticoid exposure. These observations provide a mechanism by which glucocorticoids may have a positive influence on T cell survival and function.

AN - 71476782; 11859130 AB - Dendritic cell (DC)-based vaccines are being developed for treatment of patients with cancer, in part because DC are potent inducers of CD8(+) CTL. DC MHC class I:antigenic peptide complexes that are required for CTL elicitation are most often generated by incubating DC with peptides or by transfecting (or transducing) DC with cDNAs (or viral vectors) that encode protein Ags. The former approach is feasible when MHC class I Ags and relevant peptides are known. The latter approach may be hampered by inefficient DC transfection (transduction) and/or difficulties associated with preparation and use of viral vectors. Herein we demonstrate that a bacterial recombinant model tumor-associated Ag (OVA) that contains the HIV TAT protein transduction domain (PTD) was readily engineered and purified, efficiently transduced murine lymphocytes and DC, and was processed by proteasomes for MHC class I-restricted presentation to CTL. In addition, PTD-containing rOVA was processed and presented by DC to CD4 T cells as efficiently as native OVA or rOVA lacking the PTD. PTD-OVA-transduced DC induced CTL in vivo in a Th cell-independent fashion and vaccinated against OVA-expressing tumors. In contrast, rOVA lacking the PTD did not enter the DC MHC class I presentation pathway and DC treated with this protein did not prime OVA-specific CTL in vivo. Treatment of mice harboring clinically apparent OVA-expressing tumors with PTD-OVA-transduced DC resulted in tumor regression in some animals.

AN - 71476099; 11860672 AB - In addition to T cell leukemias and lymphomas, human T cell leukemia virus type 1 (HTLV-1) infection has been associated with nonhematologic malignancies and described as the cause of one case of small-cell lung carcinoma. Infected primary epithelial cells have been isolated from sweat gland and oral mucosae of HTLV-1-infected human patients. In the present study, epithelial neoplasms developed in two rabbits experimentally infected with a molecular clone of HTLV-1 (strain K30p). Serologic detection of anti-HTLV-1 and isolation of virus from blood lymphocytes at multiple time points postinjection established a course of chronic asymptomatic infection in both. One rabbit, infected for 5.5 years after intramuscular injection of HTLV-1 DNA, developed a thymoma having features of medullary differentiation. HTLV-1 provirus was detected in both thymocytes and neoplastic epithelium isolated discretely from the thymoma by laser capture microdissection. These findings provide the first experimental evidence of HTLV-1 disease after infection by HTLV-1 DNA injection. Endometrial adenocarcinoma occurred in a second rabbit 2.5 years after its inoculation with cell-associated virus. In this second case, an epithelial cell line derived ex vivo from a metastatic lesion produced virus in culture. In tumors from each of the two rabbits, the neoplastic epithelium was infected and harbored monoclonally integrated HTLV-1 provirus. Although monoclonal provirus integration alone does not establish retroviral cause of carcinogenesis unequivocally, these and other accumulating data indicate that there may be a role for HTLV-1 in diseases associated with infection of epithelia, including some epithelial cancers.

The 28-kDa rSEB was partially purified from soluble, intracellular protein by tangential flow filtration and differential ammonium sulfate precipitation. The intermediate product was then further purified using low-pressure liquid chromatography including hydrophobic interaction, cation exchange, and size-exclusion matrices. The final vialed product was >95% pure as determined by Coomassie blue-stained sodium dodecyl sulfate-polyacrylamide gel electrophoresis, high-pressure size-exclusion chromatography, and capillary zonal electrophoresis. The endotoxin level was <0.6 EU/mg. Final estimated yield of purified rSEB was 147 mg/L of starting culture. Purified rSEB was stable, elicited an immune response in mice, and protected mice against a lethal challenge with the native toxin. Copyright 2002 Elsevier Science (USA).

Better data-collection facilities and cryogenic techniques, coupled with powerful programs for data processing, phasing, density modification and automatic model building, means that the SAD approach may gain wide popularity owing to its simplicity, less stringent wavelength requirements and faster data collection and phasing than the multi-wavelength (MAD) approach. It can be performed at any wavelength where anomalous scattering can be observed, in many cases using laboratory X-ray sources. JF - Acta crystallographica.

AN - 71455632; 11844774 AB - Recently, we observed that Staphylococcus aureus strains newly isolated from patients had twofold-higher aconitase activity than a strain passaged extensively in vitro, leading us to hypothesize that aconitase specific activity decreases over time during in vitro passage. To test this hypothesis, a strain recovered from a patient with toxic shock syndrome was serially passaged for 6 weeks, and the aconitase activity was measured. Aconitase specific activity decreased 38% (P < 0.001) by the sixth week in culture. During serial passage, S. aureus existed as a heterogeneous population with two colony types that had pronounced (wild type) or negligible zones of beta-hemolytic activity. The cell density-sensing accessory gene regulatory (agr) system regulates beta-hemolytic activity. Surprisingly, the percentage of colonies with a wild-type beta-hemolytic phenotype correlated strongly with aconitase specific activity (rho = 0.96), suggesting a common cause of the decreased aconitase specific activity and the variation in percentage of beta-hemolytic colonies. The loss of the beta-hemolytic phenotype also coincided with the occurrence of mutations in the agrC coding region or the intergenic region between agrC and agrA in the derivative strains. Our results demonstrate that in vitro growth is sufficient to result in mutations within the agr operon. Additionally, our results demonstrate that S. aureus undergoes significant phenotypic and genotypic changes during serial passage and suggest that vigilance should be used when extrapolating data obtained from the study of high-passage strains.

AN - 71453057; 11844601 AB - We report the surgical short- and long-term results in 42 patients treated in a phase II trial with 50-60 Gy cisplatin-enhanced radiotherapy (RT) and adjuvant resection, for initially non-resectable stage III non-small cell lung cancer. Six of the 42 patients had a complete response, 31 a partial response and five stable disease at the presurgical clinical restaging. A complete pathologic response was observed in 19 cases (R0a surgery); 15 complete resections were performed due to persistent disease (R0b). There were eight non-radical operations (R+). Operative deaths were seen after right pneumonectomy (five cases) and in case of a non-radical operation after no response following the chemo-radiotherapy schedule (two cases). Surgery should be contraindicated in these cases. Overall eight-year-survival was 26% (37% in R0a and 27% in R0b patients). No patient with R+ surgery survived at the eighth year. A local progression as initial failure occurred in four of the 34 R0 patients, and in five of the eighth with a R+ procedure. Resection seems to improve local control, but its role needs further definition. However, advanced stage III patients treated only with a local therapy were not precluded from a long-term survival.

AN - 71452222; 11850152 AB - We have extended our previous work investigating the neural correlates of cue-induced cocaine craving through the use of positron emission tomography with greater spatial resolution (<4.6 mm), an evocative script, and a pixel-by-pixel analysis. Craving and cerebral glucose metabolism were measured after presentation of cocaine-related or neutral cues to 11 cocaine abusers. Cocaine cues elicited a higher degree of craving than has been previously reported and resulted in left hemispheric activation of lateral amygdala, lateral orbitofrontal cortex, and rhinal cortex and right hemispheric activation of dorsolateral prefrontal cortex and cerebellum. The intensity of activation in these areas (except cerebellum), as well as left insula, was also correlated with craving. Deactivation occurred in left ventral pole and left medial prefrontal cortex. The results suggest that induction of drug craving involves a neural network that assigns incentive motivational value to environmental stimuli through the coactivation of brain regions that process information about memories and emotions.

AN - 71452174; 11850144 AB - Several lines of evidence suggest that changes in dopamine release and/or post-synaptic sensitivity may be involved in the pathogenesis of tardive dyskinesia (TD). Preclinically, increased D(2) receptor sensitivity and dopamine turnover are associated with D(2) receptor antagonism. Clinically, development of TD is associated with D(2) receptor antagonist administration. Eight patients with mild evidence of TD (AIMS ratings > or =14) and six without (AIMS = 10), underwent [(11)C]raclopride PET scans. Baseline and amphetamine-induced decrements in striatal specific binding were assessed. Baseline and amphetamine-induced decrements in specific binding did not differ between patients with and without evidence of mild TD (p =.53). AIMS ratings did not significantly correlate with baseline (p =.76) or decrements in specific binding (p =.45). This study provides evidence that TD is not associated with increased amphetamine-induced presynaptic dopamine release and/or D(2) receptor binding as measured by [(11)C]raclopride PET. More research is needed to unravel the neurobiology of this debilitating disorder.

AN - 71451846; 11835998 AB - Neuropeptide FF (NPFF) is an endogenous anti-opioid peptide. NPFF could potentiate the naloxone-precipitated morphine withdrawal syndromes in morphine-dependent rats, indicating the possible involvement of the endogenous NPFF system in opioid analgesia and dependence. The present study was performed to examine the effects of dansyl-PQRamide (dns-PQRa), a putative NPFF antagonist, on conditioned place preference (CPP), in addition, its interaction with the opioid system. Two CPP experiments were conducted. First, rats were treated with dns-PQRa (4-13 mg/kg, i.p.) and paired with the non-preferred compartment while the vehicle was paired with the preferred compartment. Second, similar to experiment 1 except naloxone (1 mg/kg, i.p.) was given 10 min prior to each dns-PQRa administration. The post-drug place preference was examined after 4 alternative pairings. Another group of animals after repetitive dns-PQRa treatments were analyzed for levels of neurotransmitters in discrete brain areas. Dns-PQRa (4-13 mg/kg, i.p.) induced a significant dose-dependent CPP. The dns-PQRa-induced CPP was completely blocked by pretreatment with 1 mg/kg i.p. naloxone, while naloxone alone did not induce any place aversion. The chronic dns-PQRa-treated (13 mg/kg, i.p., b.i.d.) rats caused a significant increase in 3,4-dihydroxyphenylacetic acid and 5-hydroxyindoleacetic acid in the olfactory tubercle compared to the vehicle-treated controls. There was also an increase in the turnover of serotonin in the olfactory tubercle, nucleus accumbens and medial prefrontal cortex. These results suggest that blockade of the NPFF system produces rewarding, possibly via an inhibition of the anti-opioid action of NPFF. These results also reveal a close relationship between NPFF, drug rewarding and the dopaminergic and serotoninergic neurons in the mesolimbic system.

AN - 71445023; 11836714 AB - Patients with recurrent Ewing sarcoma and alveolar rhabdomyosarcoma have poor prognoses and limited therapeutic options. We have investigated the use of peptide pulsed vaccination in an attempt to immunologically target the breakpoint region of tumor specific fusion proteins expressed in these tumors. Sixteen patients with recurrent, translocation positive, Ewing sarcoma, and alveolar rhabdomyosarcoma underwent apheresis for collection of peripheral blood mononuclear cells. Following countercurrent centrifugal elutriation, an apheresis product comprised predominantly of monocytes but containing small numbers of circulating immature dendritic cells was pulsed with peptides derived from the breakpoint region of the fusion proteins. Vaccines were administered intravenously concomitant with continuous intravenous rhIL-2 at 9 x 10(6) IU/m(2)/day. Toxicity was limited to IL-2 related effects and was generally mild. Following vaccination, all patients showed progressive disease, most in a rapid fashion following the first vaccine. One patient showed evidence of an immunologic response and another showed a mixed clinical response. Patients enrolled on this tumor vaccine trial showed significant immunosuppression and large bulky tumors. Peptide vaccination as administered in this trial did not alter the dismal clinical outcome for patients with recurrent pediatric sarcomas. Future trials of tumor vaccines in this population should target patient populations with improved immune competence and smaller tumor burdens. Furthermore, optimization of the antigen presenting cell populations may be important for inducing immune responses to peptide antigens. Published 2002 Wiley-Liss, Inc.

AN - 71439464; 11839804 AB - Transforming growth factor beta (TGF-beta) induces apoptosis in a variety of cells. We have previously shown that TGF-beta 1 rapidly induces apoptosis in the FaO rat hepatoma cell line. We have now studied the effect of TGF-beta 1 on the expression of different members of the Bcl-2 family in these cells. We observed no detectable changes in the steady-state levels of Bcl-2, Bcl-X(L), and Bax. However, TGF-beta 1 induced caspase-dependent cleavage of BAD at its N terminus to generate a 15-kDa truncated protein. Overexpression of the 15-kDa truncated BAD protein enhanced TGF-beta 1-induced apoptosis, whereas a mutant BAD resistant to caspase 3 cleavage blocked TGF-beta 1-induced apoptosis. Overexpression of Smad3 dramatically enhanced TGF-beta 1-induced cleavage of BAD and apoptosis, whereas antisense Smad3 blocked TGF-beta 1-induced apoptosis and BAD cleavage. These results suggest that TGF-beta 1 induces apoptosis through the cleavage of BAD in a Smad3-dependent mechanism.

AN - 71414830; 11793390 AB - Corticosteroid use in transplant recipients increases the incidence and severity of Kaposi's sarcoma (KS), a disease associated with KS-associated herpesvirus (KSHV) infection. Recently, the prototypic corticosteroid, hydrocortisone, was shown to directly induce lytic cycle reactivation of KSHV in latently-infected BCBL-1 cells. The purpose of this study was to examine this phenomenon in further detail. After incubation with dexamethasone ( 3 cm) or locally advanced (Stage III) breast carcinoma, including patients with inflammatory breast carcinoma. In this single-center, open-label, single-stage, Phase II trial, epirubicin (75 mg/m(2); intravenous bolus) followed by docetaxel (80 mg/m(2); 1-hour intravenous infusion) was administered on Day 1 of each cycle for four cycles. Nine of 30 patients (30%) had inflammatory breast carcinoma. Twenty-three patients (76.7%; 95% confidence interval, 57.7-90.1) had a clinical objective response that was complete in 6 patients (20%). Twenty-seven patients (90%) underwent surgery that was conservative in 5 patients (16.7%). Pathologic response evaluation revealed four complete responses (13.3%; 95% confidence interval, 3.8-30.7). Grade 4 neutropenia was recorded in 80.0% of patients, and febrile neutropenia was recorded in one-third of patients. Anemia and thrombocytopenia were never severe.

AN - 71507820; 11884234 AB - Recent evidence suggests that K-ras protooncogene protein p21 may have a tumor-suppressive role in the context of development of lung adenocarcinoma. Levels of K-ras p21, raf-1, mitogen-activated protein kinases Erk 1 and 2, the phosphorylated-activated forms of Erk 1 and 2 (Erk 1P and 2P), and proliferating cell nuclear antigen (PCNA) were measured by immunoblotting in mouse lung tumors (5 to 9 mm in size) caused by N-nitrosodimethylamine (NDMA) and in control lungs. In tumors compared with normal lung, cell membrane-associated K-ras p21 was significantly decreased and cytosolic K-ras p21 increased. Total, membrane, and cytosolic raf-1 and Erk 1P and 2P were increased in tumors compared with normal lung. A single dose of 5 nmol/kg 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) given after NDMA resulted in a significant 2.4-fold increase in tumor multiplicity. A significantly greater decrease in membrane-associated K-ras p21 and increase in total and membrane associated raf-1 occurred in the NDMA/TCDD tumors compared with the NDMA-only tumors. PCNA levels increased in tumors, a finding confirmed by immunohistochemistry, and correlated with tumor size after NDMA/TCDD treatment but not after NDMA only. The increase in raf-1 in the tumors was confirmed by immunohistochemistry, which also revealed an increase in raf-1-positive alveolar macrophages specifically associating with tumors from the earliest stages. These results suggest a possible tumor-suppressive function for K-ras p21 in lung and a positive role for raf-1 and Erk 1/2 in lung tumorigenesis. TCDD may promote tumors by contributing to downregulation of K-ras and stimulation of raf-1.

Proteasome inhibitors provide a rational approach to control constitutively activated NF-kappaB in human T-cell lymphotrophic virus I-infected T cells. We report that the proteasome inhibitor PS-341 decreased NF-kappaB DNA binding activity by preventing degradation of IkappaB(alpha). In our murine model of adult T-cell leukemia, PS-341 used alone did not yield prolongation of the survival of tumor-bearing mice. However, when combined with the current clinically approved drug humanized anti-Tac, therapy with PS-341 was associated with a complete remission in a proportion of treated animals, whereas only a partial response was observed in animals treated with humanized anti-Tac alone.

AN - 71453790; 11744689 AB - Transcriptional repression of the transforming growth factor-beta (TGF-beta) type II receptor (TbetaRII) gene is one of several mechanisms leading to TGF-beta resistance. Previously, we have shown that MS-275, a synthetic inhibitor of histone deacetylase (HDAC), specifically induces the expression of the TbetaRII gene and restores the TGF-beta signaling in human breast cancer cell lines. However, little is known about the mechanism by which inhibition of HDAC activates TbetaRII expression. MS-275 treatment of cells expressing a wild-type TbetaRII promoter/luciferase construct resulted in a 10-fold induction of the promoter activity. DNA transfection and an electrophoretic mobility shift assay showed that the induction of the TbetaRII promoter by MS-275 requires the inverted CCAAT box and its cognate binding protein, NF-Y. In addition, a DNA affinity pull-down assay indicated that the PCAF protein, a transcriptional coactivator with intrinsic histone acetyltransferase (HAT) activity, is specifically recruited to the NF-Y complex in the presence of either MS-275 or trichostatin A. Based on these results, we suggest that treatment with the HDAC inhibitor induces TbetaRII promoter activity by the recruitment of the PCAF protein to the NF-Y complex, interacting with the inverted CCAAT box in the TbetaRII promoter.

AN - 71448319; 11836195 AB - 1,1-Dichloro-2,2-bis(p-chlorophenyl)ethylene (p,p'-DDE) is a metabolite of the insecticide 2,2-bis(p-chlorophenyl)-1,1,1-trichloroethane (DDT) and is a ubiquitous environmental contaminant. Nearly everyone in the United States has a detectable serum level of DDE. DDE was recently found to inhibit binding of androgen to its receptor and to block androgen action in rodents. Normal development of male genitalia in mammals depends on androgen action. The authors used stored serum samples to examine the relation between maternal DDE levels during pregnancy and adjusted odds of cryptorchidism (n = 219), hypospadias (n = 199), and polythelia (extra nipples) (n = 167) among male offspring, using a nested case-control design with one control group (n = 552). Subjects were selected from the Collaborative Perinatal Project, a US birth cohort study begun in 1959-1966, when DDE levels were much higher than they are at present. Compared with boys whose mother's recovery-adjusted serum DDE level was less than 21.4 microg/liter, boys with maternal levels greater than or equal to 85.6 microg/liter had adjusted odds ratios of 1.3 (95% confidence interval (CI): 0.7, 2.4) for crypt-orchidism, 1.2 (95% CI: 0.6, 2.4) for hypospadias, and 1.9 (95% CI: 0.9, 4.0) for polythelia. For cryptorchidism and polythelia, the results were consistent with a modest-to-moderate association, but in no instance was the estimate very precise. The results were inconclusive.

AN - 71440697; 11823506 AB - Aberrant expression of IFN-gamma has been demonstrated to cause a wide variety of alterations in cell function and development. Previously we reported that constitutive expression of IFN-gamma in bone marrow (BM) and thymus results in a total absence of B cells and a substantial decrease in the number of hematopoietic progenitor cells. In this study, we demonstrate a severe deficiency of NK1.1(+)CD3(-) cells in this transgenic mouse model. Compared with normal control littermates, we found a pronounced reduction of NK cells in IFN-gamma transgenic mouse spleen and liver despite maintenance of normal function. In addition, we observed a reduced number of BM cells in the IFN-gamma transgenic mouse despite normal expression of hematopoietic growth factors in the BM. Interestingly, these cells were less responsive to stem cell factor (SCF) despite c-kit expression on hematopoietic stem cells (HSCs). We observed that addition of exogenous IFN-gamma inhibited proliferation of HSCs and differentiation of NK precursors from HSCs in normal mice in response to SCF, IL-7, fms-like tyrosine kinase 3 ligand, and IL-15. Furthermore, we found that HSCs express the IFN-gammaRalpha subunit and undergo apoptosis in response to exogenous IFN-gamma. Thus, we have demonstrated the occurrence of a severe deficiency of NK cells and lower numbers of BM cells in an IFN-gamma transgenic mouse model. Furthermore, because exogenous IFN-gamma affects the responsiveness to hematopoietic growth factors such as SCF in vitro, our results indicate that chronic expression of IFN-gamma in vivo leads to widespread immune system defects, including alterations in NK cell differentiation.

The simulations show that the unfolding generally involves an initial end-to-end collapse of the adenine binding domain into partially extended loops, followed by a gradual breakdown of the remaining beta -sheet core structure. The core, which consists of beta -strands 5-7, was observed to be the most resistant to thermal unfolding. This region, which is made up of part of the N-terminus domain and part of the large domain of the E. coli dihydrofolate reductase, may constitute the nucleation site for protein folding and may be important for the eventual formation of both domains. The unfolding of different domains at different stages of the unfolding process suggests that protein domains vary in stability and that the rate at which they unfold can affect the overall outcome of the unfolding pathway. This observation is compared with the recently proposed hierarchical folding model. Finally, the results of the simulation were found to be consistent with a previous experimental study (Frieden, Proc Natl Acad Sci USA 1990; 87:4413-4416) which showed that the folding process of E. coli dihydrofolate reductase involves sequential formation of the substrate-binding sites.

J., Iadarola, M. J., and O'Connell, B. C., Nat. Biotech. 18, 176-180, 2000). To determine the source of this expression we examined two epithelial cell lines. One, HSG, permits E1 super(-) recombinant adenoviral replication, while the other, A5, does not. An HSG clone, that expressed luciferase stably for >6 months, was obtained following infection at similar to 0.2 AdLTR-luc particles/cell. Southern and PCR analyses showed that luciferase cDNA present was integrated. A5 cells were infected with AdLTR-luc at similar to 1000 particles/cell, and colonies were obtained by limiting dilution. Eight clones showed stable luciferase activity for >9 months. High molecular weight DNA extracts from clones were positive for genomic integration by Southern, PCR, and quantitative PCR analyses. Similar analyses of low molecular weight DNA extracts indicated the absence of intact extrachromosomal vector. These data demonstrate that long-term luciferase expression after infection by AdLTR-luc is derived from the integrated cDNA.

AN - 71488453; 11870530 AB - Based on the assumption that an accelerated proliferation process prevails in tumour cell residues after surgery, the possibility that treatment acceleration would offer a therapeutic advantage in postoperative radiotherapy of locally advanced head and neck cancer was investigated. The value of T(pot) in predicting the treatment outcome and in selecting patients for accelerated fractionation was tested. Seventy patients with (T2/N1-N2) or (T3-4/any N) squamous cell carcinoma of the oral cavity, larynx and hypopharynx who underwent radical surgery, were randomized to either (a) accelerated hyperfractionation: 46.2 Gy per 12 days, 1.4 Gy per fraction, three fractions per day with 6 h interfraction interval, treating 6 days per week or (b) Conventional fractionation: 60 Gy per 6 weeks, 2 Gy per fraction, treating 5 days per week. The 3-year locoregional control rate was significantly better in the accelerated hyperfractionation (88 +/- 4%) than in the CF (57+/- 9%) group, P=0.01 (and this was confirmed by multivariate analysis), but the difference in survival (60 +/- 10% vs 46 +/- 9%) was not significant (P=0.29). The favourable influence of a short treatment time was further substantiated by demonstrating the importance of the gap between surgery and radiotherapy and the overall treatment time between surgery and end of radiotherapy. Early mucositis progressed more rapidly and was more severe in the accelerated hyperfractionation group; reflecting a faster rate of dose accumulation. Xerostomia was experienced by all patients with a tendency to be more severe after accelerated hyperfractionation. Fibrosis and oedema also tended to be more frequent after accelerated hyperfractionation and probably represent consequential reactions. T(pot) showed a correlation with disease-free survival in a univariate analysis but did not prove to be an independent factor. Moreover, the use of the minimum and corrected P-values did not identify a significant cut-off. Compared to conventional fractionation, accelerated hyperfractionation did not seem to offer a survival advantage in fast tumours though a better local control rate was noted. This limits the use of T(pot) as a guide for selecting patients for accelerated hyperfractionation. For slowly growing tumours, tumour control and survival probabilities were not significantly different in the conventional fractionation and accelerated hyperfractionation groups. A rapid tumour growth was associated with a higher risk of distant metastases (P=0.01). In conclusion, tumour cell repopulation seems to be an important determinant of postoperative radiotherapy of locally advanced head and neck cancer despite lack of a definite association between T(pot) and treatment outcome. In fast growing tumours accelerated hyperfractionation provided an improved local control but without a survival advantage. To gain a full benefit from treatment acceleration, the surgery-radiotherapy gap and the overall treatment time should not exceed 6 and 10 weeks respectively.

In these trials, the levels of gene transduction and expression in hematopoietic cells have been assessed by DNA- or RNA-based assays and measurement of ADA enzyme activity. Although informative, these methods are rarely applied to clonal analysis. The results of these assays therefore provide best estimates of transduction efficiency and gene expression in bulk populations based on the assumption that gene transfer and expression are uniformly distributed among transduced cells. As a useful additional tool for evaluation of ADA gene expression, we have developed a flow cytometry (fluorescence-activated cell sorting, FACS) assay capable of estimating the levels of intracellular ADA on a single-cell basis. We validated this technique with T cell lines and peripheral blood mononuclear cells (PBMCs) from ADA-deficient patients that showed severely reduced levels of ADA expression (ADA-dull) by FACS and Western blot analyses. After retrovirus-mediated ADA gene transfer, these cells showed clearly distinguishable populations exhibiting ADA expression (ADA-bright), thus allowing estimation of transduction efficiency. By mixing ADA-deficient and normal cells and using enzymatic amplification, we determined that our staining procedure could detect as little as 5% ADA-bright cells. This technique, therefore, will be useful to quickly assess the expression of ADA in hematopoietic cells of severe combined immunodeficient patients and represents an important tool for the follow-up of patients treated in clinical gene transfer protocols.

For example, New World spadefoot toads (Scaphiopus and Spea) have the shortest larval periods known among anurans, and the tadpoles of Old World spadefoot taxa (Pelobates) are among the largest known. To analyze the patterns of this diversity in an evolutionary context, we generated comparable larval growth and development data from 10 of the 11 taxa of spadefoot toads and from one taxon of parsley frog (Pelodytes), the nearest spadefoot toad relative. We found dramatic differences in growth and development among taxa, which indicated that taxon-specific physiology, rather than phenotypic plasticity, underlies larval period diversity. For all eight response variables (development rate, three growth rates, time to forelimb emergence, time to tail resorption, mass at tail resorption, and body length at tail resorption), taxa within genera were similar to each other and were different from taxa in other genera. Larvae of Scaphiopus were small with short larval periods, larvae of Spea were large with short larval periods, larvae of Pelobates were large with long larval periods, and larvae of Pelodytes were small with long larval periods. Even though taxa within the same genus live in different environments, larval growth and development correlated with phylogenetic groupings rather than breeding habitat. Mapping larval data onto a molecular phylogeny indicated that short larval periods, as well as rapid embryonic development and high temperature tolerance, originated within the spadefoot toad family.

AN - 71433385; 11830608 AB - Lung cancer is a frequent cause of death in patients cured of Hodgkin's disease, but the contributions of chemotherapy, radiotherapy, and smoking are not well described. We quantified the risk of treatment-associated lung cancer, taking into account tobacco use. Within a population-based cohort of 19 046 Hodgkin's disease patients (diagnosed from 1965 through 1994), a case-control study of lung cancer was conducted. The cumulative amount of cytotoxic drugs, the radiation dose to the specific location in the lung where cancer developed, and tobacco use were compared for 222 patients who developed lung cancer and for 444 matched control patients. All statistical tests were two-sided. Treatment with alkylating agents without radiotherapy was associated with increased lung cancer risk (relative risk [RR] = 4.2; 95% confidence interval [CI] = 2.1 to 8.8), as was radiation dose of 5 Gy or more without alkylating agents (RR = 5.9; 95% CI = 2.7 to 13.5). Risk increased with both increasing number of cycles of alkylating agents and increasing radiation dose (P for trend <.001). Among patients treated with mechlorethamine, vincristine, procarbazine, and prednisone (MOPP), risk increased with cumulative amounts of mechlorethamine and procarbazine (P<.001) when evaluated separately. Statistically significantly elevated risks of lung cancer were apparent within 1-4 years after treatment with alkylating agents, whereas excess risk after radiotherapy began 5 years after treatment and persisted for more than 20 years. Risk after treatment with alkylating agents and radiotherapy together was as expected if individual excess risks were summed. Tobacco use increased lung cancer risk more than 20-fold; risks from smoking appeared to multiply risks from treatment. Past treatments with alkylating agents and radiation therapy for Hodgkin's disease were associated with an increased risk of lung cancer in a dose-dependent and additive fashion. The precise risk estimates, however, should be interpreted cautiously, given the possible residual and enhancing effects of tobacco.

AN - 71447400; 11830658 AB - We previously identified five derivatives of Klenow fragment DNA polymerase that have lower fidelity because of amino acid substitutions in the polymerase active site. One of these has alanine substituted for the invariant Glu-710, whose side chain interacts with the deoxyribose of the incoming dNTP. Here we show that the E710A enzyme has reduced fidelity for five of the 12 possible mismatches. All but one of these involve misinsertion of pyrimidines, including two transition mismatches A-dCTP and G-dTTP. In contrast, E710A polymerase error rates for the reciprocal C-dATP and T-dGTP transition mismatches were similar to those of the wild-type enzyme. The kinetics of formation of correct base pairs and transition mismatches by the wild-type and E710A polymerases, combined with information on the structure of the DNA polymerase active site and the asymmetry of wobble base pairs, provides a plausible explanation for the differential effects of the E710A mutation on fidelity. The data suggest that the Glu-710 side chain plays a pivotal role in excluding wobble base pairs between template pyrimidines and purine triphosphates by steric clash. Moreover, this same side chain enhances the stability of incoming correct dNTPs, such that loss of this interaction on removal of the side chain leads to lower selectivity against mismatches involving incoming pyrimidines.

AN - 71439242; 11827493 AB - Although excessive alcohol consumption can promote cardiomyopathy, little is known about the association between alcohol consumption and risk for congestive heart failure in the community. To determine the relation between alcohol consumption and risk for congestive heart failure in the community. Community-based, prospective observational study. Framingham, Massachusetts. Participants in the Framingham Heart Study who were free of congestive heart failure and coronary heart disease. Self-reported alcohol consumption; sex-specific rates of congestive heart failure per 1000 person-years of follow-up by level of alcohol consumption. In men, 99 cases of congestive heart failure occurred during 26 035 person-years of follow-up. In women, 120 cases of congestive heart failure occurred during 35 563 person-years of follow-up. After adjustment for multiple confounders, risk for congestive heart failure was lower among men at all levels of alcohol consumption compared with men who consumed less than 1 drink/wk. The hazard ratio for congestive heart failure was lowest among men who consumed 8 to 14 drinks/wk (0.41 [95% CI, 0.21 to 0.81]) compared with those who consumed less than 1 drink/wk. In women, the age-adjusted hazard ratio for congestive heart failure was lowest among those who consumed 3 to 7 drinks/wk (0.49 [CI, 0.25 to 0.96]) compared with those who consumed less than 1 drink/wk. However, after adjustment for multiple predictors of congestive heart failure, this association was no longer statistically significant. In the community, alcohol consumption is not associated with increased risk for congestive heart failure, even among heavy drinkers (> or = 15 drinks/wk in men and > or = 8 drinks/wk in women). To the contrary, when consumed in moderation, alcohol appears to protect against congestive heart failure.

In this study, lingual histology is examined by identifying three types of connective tissues, including collagen, elastin, & adipose tissue, within defined muscle regions. Using stained tissue components, the percent concentration of each of these tissues was derived. Tissue samples (N = 10) were taken from the same section of multiple tongues for the anterior, medial, & posterior regions. The results of statistical analyses of tissue concentration percentage demonstrate that the anterior region contains a greater proportion of connective tissue & fat, whereas posterior regions contained the greatest amount of muscle content. The distribution & organization of lingual tissue in each of the three regions showed a high degree of variation. No statistical effects of age or sex-related differences were found in any of the constituent elements of the tongue. Implications of this research for lingual biomechanics & histopathology are discussed. 3 Tables, 70 References. L.

Auditory brainstem responses and otoacoustic emissions were analyzed in 2 subjects.Four subjects had prelingual, bilateral, profound sensorineural hearing loss, whereas the fifth subject had significant residual hearing that exhibited no progression on serial audiograms. All 5 subjects had a history of non-erosive keratosis obturans and cutaneous cysts in the external ear canals that prevented continuous use of ear molds.The sensorineural hearing loss in KID syndrome is generally prelingual and profound. This combination of auditory and cutaneous phenotypes is similar to those previously reported for KID syndrome. KID syndrome presents a difficult challenge for communication rehabilitation because keratitis may impair the perception of sign and spoken language, and the cutaneous manifestations routinely curtail use of external amplification devices.

AN - 85366086; pmid-11782611 AB - Although the gastrointestinal tract is the most common site of extranodal non-Hodgkin's lymphoma (NHL), primary small intestine lymphomas remain relatively rare, especially localized low-grade follicular B-cell lymphomas. When lymphomas do occur at this site, most are high grade and require aggressive therapy. We report three cases of small intestinal follicular lymphoma diagnosed on endoscopic biopsy and review the clinical history, pathologic features, and treatment outcome.A review of the medical records and pathology from three cases of small intestine follicular NHL was performed. The pathology specimens were formalin-fixed, paraffin-embedded tissues processed for routine microscopic examination, immunohistochemical staining, and molecular analysis.Histologic and immunophenotypical studies were diagnostic of grade 1 follicular lymphoma (Revised European-American Lymphoma classification/World Health Organization classification). All cases expressed bcl-2 protein, and polymerase chain reaction analysis supported the diagnosis in two cases with adequate DNA. With 23.3 months' median follow-up, one untreated and one treated patient were alive without symptoms; a third untreated patient died of a nonlymphoma cause.Isolated indolent lymphomas of the small intestine are rare. Accurate pathologic staging and histologic classification are paramount in delineating treatment options.

The anterior--posterior diameter of the hypopharynx was measured at the level of the superior edge of the epiglottis at baseline and during NS from recorded video endoscopic examinations.NS of the genioglossus muscle resulted in a significant increase in the diameter of the hypopharyngeal airway (P =.002) compared with baseline, ranging from a 33% to 284% increase in airway diameter. Three of the 14 patients demonstrated modest decreases in airway diameter, likely the result of faulty electrode placement in surrounding tongue retrusive muscles.NS of the genioglossus muscle was effective in increasing the hypopharyngeal airway and may provide a useful alternative to direct stimulation of the hypoglossal nerve with a nerve cuff electrode in the development of neuroprosthetic treatments for obstructive sleep apnea.

AN - 85248188; pmid-11818823 AB - The purpose of this project was to assess the feasibility of imaging the velopharynx of adult volunteers during repetitive speech, using gated magnetic resonance imaging (MRI). Although a number of investigators have used conventional MRI in the study of the human vocal tract, the mismatch between the lengthy time necessary to acquire sufficiently detailed images and the rapidity of movement of the vocal tract during speech has forced investigators to acquire images either while the subject is at rest or during sustained utterances. The technique used here acquired a portion of each image during repetitive utterances, building the full image over multiple utterance cycles. The velopharyngeal portal was imaged on a 1.5-Tesla GE Signa LX 8.2 platform with gated fast spoiled gradient echo protocol. An external 1-Hertz trigger was fed to the cardiac gate. Subjects synchronized utterance of consonant-vowel syllables to a flashing light synchronized with the external trigger. Each acquisition of 30 phases per second at a single-slice location took 22 to 29 seconds. Four consonant-vowel syllables (/pa/, /ma/, /sa/, and /ka/) were evaluated. Subjects vocalized throughout the acquisition, beginning 5 to 6 seconds beforehand to establish a regular rhythm. Imaging of the velopharyngeal portal was performed for sagittal, velopharyngeal axial (aligned perpendicular to the "knee" of the velum), axial, and coronal planes. Volumes were obtained by sequential acquisition of six to 10 slices (each with 30 phases) in the axial or sagittal planes during repetition of the /pa/ syllable. Spatiotemporal volumes of the single-slice data were sectioned to provide time-motion images (analogous to M-mode echocardiograms). Three-dimensional dynamic volume renderings of palate motion were displayed interactively (Vortex; CieMed, Singapore). A method suitable for the collection and visualization of four-dimensional information regarding monosyllabic speech using gated MRI was developed. These techniques were applied to a population of adult volunteer subjects with no history of speech problems and two patients with a history of cleft lip and palate. The techniques allowed good real-time visualization of velopharyngeal anatomy during its entire range of motion and was also able to image pathology-specific anatomic differences in the subjects with cleft lip and cleft palate.

AN - 71885715; 12102499 AB - ROS are diverse and abundant in biological systems. While excessive ROS production clearly damages DNA, low levels of ROS affect cell signaling particularly at the level of redox modulation. Moreover, the specific contributions of ROS to apoptosis and mitogenesis in maintenance of cell number homeostasis remains to be elucidated. ROS dose is a critical parameter in determining the ultimate cellular response; however the shape of the dose response curve is unpredictable. When cells are stimulated with ROS, cell-signaling cascades are activated. It appears that the cellular redox potential is an important determinant of cell function and interruption of redox balance may adversely affect cell function. As a result, compounds such as antioxidants may intercept critical ROS signaling molecules and both protect cells and foster pathogenesis. As a result, further study is needed to unravel the role of ROS in redox regulation and the potential outcome of antioxidant administration on cellular responses.

AN - 71883615; 12102500 AB - A number of xenobiotics require redox reactions to form the reactive intermediates involved in the ultimate toxic events (e.g., adduct formation). The same mechanisms lead to the formation of reactive oxygen species (ROS), which can themselves exert direct toxicity including, e.g., DNA oxidative damage or glutathione depletion. The occurence of both mechanistic features in xenobiotic activation and toxicity may raise some difficulties in ascertaining the respective roles of reactive intermediates versus ROS-related mechnisms. An example is provided by the toxicity mechanisms of mitomycin C (MMC) and diepoxybutane (DEB), which are commonly referred to as 'cross-linkers'. Their toxic actions, however, are well-known to be modulated via redox parameters, such as oxygen tension, antioxidants levels, or thioredoxin overexpression. The diagnostic assessment of Fanconi's anaemia (FA) relies on MMC and DEB sensitivity, which is usually referred to as 'cross-linker sensitivity'; thus the redox-dependent toxicities of MMC and DEB may have direct implications for the definition of FA phenotype. Another major aspect in ROS formation relies on the extensive evidence pointing to the requirement for oxidative, as well as nitrosative activities in triggering a number of key events in cell division and differentiation, and in early embryogenesis. In turn, antioxidants that may prevent ROS-associated cellular damage in adult cells may prove to exert adverse or fatal outcomes when administered in early life stages. The overall information available on xenobiotic redox biotransformation and on the physiopathological roles of ROS points to the need of addressing ad hoc studies that should take into account the multiplicity of mechanistic events involved.

AN - 71822809; 12064513 AB - Reserpine inhibited batrachotoxin-elicited sodium influx in guinea pig brain synaptoneurosomes with an IC50 of about 1 microM. In the presence of brevetoxin the IC50 increased to about 80 microM. Reserpine inhibited binding of batrachotoxinin-A [3H]benzoate ([3H]BTX-B) binding in a complex manner causing a partial inhibition from 0.001 to 0.08 microM, then a rebound stimulation from 0.1 to 0.8 microM, followed by complete inhibition by 80 microM. The stimulation was prevented by the presence of brevetoxin; reserpine then smoothly inhibited binding with an IC50 of about 1 microM. Reserpine at 1 microM slightly reduced the off-rate of [3H]BTX-B binding measured in the presence of veratridine, while at a concentration of 50 microM it enhanced the off-rate, presumably by an allosteric mechanism. Reserpine at 0.3-10 microM elicited a partial inhibition of the binding of [3H]brevetoxin-3. The local anesthetic dibucaine had effects similar to reserpine: It partially inhibited binding of [3H]brevetoxin. The presence of brevetoxin reduced the potency of dibucaine as an inhibitor of batrachotoxin-elicited sodium influx from an IC50 of about 2 microM to an IC50 of about 50 microM. The results suggest that reserpine binds at both a local anesthetic site to cause allosteric inhibition of batrachotoxin-binding and action, but that it also binds to another site causing, like brevetoxin, an enhancement of batrachotoxin-binding and action. Local anesthetics also may bind to the brevetoxin site.

AN - 71596843; 11950241 AB - Choroidal neovascularization (CNV) is the leading cause of severe vision loss associated with age-related macular degeneration. As the pathogenesis of CNV formation is better understood, mechanism-based therapies, including the use of antiangiogenesis inhibitors, have been investigated. 2-methoxyestradiol (2ME2), an endogenous metabolite of estradiol, has been shown in the chick allantoic membrane model and the corneal micropocket assay to have antiangiogenic properties. The authors sought to determine the safety and pharmacokinetics of sustained-release intravitreal 2ME2 implants in normal rabbit and their efficacy in a rat model of CNV. 2ME2 implants were constructed using two designs: implant A, a silicone-based reservoir implant for the rabnbit eye, and implant B, a microimplant matrix design for the rat eye. In vitro release rates of both implants were determined. New Zealand white (NZW) rabbits had implant A placed in the vitreous cavity of one eye and the ocular toxicity was evaluated by clinical examination, serial electroretinography (ERG), and histopathology over a 28 week period. The steady state clearance of 2ME2 in the rabbit eye was calculated from in vivo release rates divided by steady state vitreous concentrations. A CNV model in the Brown-Norway rat was performed by injecting an adenoviral vector encoding human vascular endothelial growth factor in the subretinal space. Following the injection, a 2ME2 or sham (no drug) microimplant was placed in the vitreous cavity. Animals were killed over a 3 week period and the eyes examined for CNV by histopathology. Results showed that following a short burst, the release rate of implant A followed zero-order kinetics, typical of reservoir devices, and the cumulative release of implant B was proportional to the square root of time, as expected for a matrix delivery device. The safety studies in normal rabbit showed no ocular toxicities by clinical examination, ERG, and histopathology. Pharmacokinetic evaluation in the rabbit showed mean 2ME2 vitreous levels within the therapeutic range for the inhibition of endothelial cell proliferation. The experimental rat model showed a significant reduction in CNV in eyes treated with the 2ME2 implant. In conclusion, sustained-release 2ME2 intravitreal implants, which can be designed to deliver potentially therapeutic vitreous levels of 2ME2 for an extended period of time, appeared to be safe in normal rabbit and effective in a rat model of CNV. Sustained-release 2ME2 intravitreal implants may hold promise in the treatment of recurrent CNV refractory to standard therapy. Copyright 2002 Elsevier Science Ltd.

AN - 71578228; 11942045 AB - The field of cancer prevention is advancing rapidly, largely owing to post-genomic technology that has revolutionized our ability to identify and characterize molecular profiles for cancer. Advances in colorectal cancer screening (e.g., endoscopy, fecal occult blood testing, and mutational analysis) have made the detection and eradication of preinvasive neoplastic lesions the standard of care. Basic and translational sciences are building on these advances, and continue to expose molecular hallmarks of carcinogenesis that can be exploited as targets for molecularly targeted preventive interventions (i.e., chemoprevention). These targets will help identify more effective and better tolerated preventive agents. Carcinogenesis is now recognized as a disease in itself and has become the target of an ever-expanding array of preventive interventions.

We discovered six single nucleotide polymorphisms (SNPs) in the CHRNB2 gene by surveying 15.4 kb of genomic sequence including a previously undescribed 3' untranslated region that extends 4.0 kb downstream of the coding region. One of the SNPs causes an amino acid substitution in exon 5, one occurs in the promoter region, one changes an intronic base, and three occur in the 3' untranslated region. The ethnically dependent allele frequencies and the marker-to-marker linkage disequilibrium patterns of five of these polymorphisms were determined. The SNPs were assayed in 743 individuals for whom information on smoking history and lifelong nicotine dependence was available. No significant associations of the individual markers or their haplotypes to smoking behavior or level of nicotine dependence were found.

AN - 71552062; 11915304 AB - To estimate the lifetime prevalence of solvent abuse among general junior high school students in Chiba prefecture and to understand their background lifestyle, in 1994 the author surveyed 6,795 students enrolled in 15 junior high schools. The lifetime prevalence of solvent abuse was 1.9% in males, 1.1% in females and 1.5% of the total. This implied that the lifetime prevalence of solvent abuse was decreasing year-on-year in males, had recovered to the 1990 level in total, but had stagnated between the 1990 level and the 1992 level in females. The regularity of daily life was more significantly disturbed in Lifetime Users than in Non-Users. School life and family life were significantly less relaxed for Lifetime Users than for Non-Users. Cigarette smoking and some types of alcohol drinking were strongly related to solvent abuse. More Lifetime Users than Non-Users were aware of harmful effects of solvent abuse.

AN - 71524444; 11895178 AB - Contextual stimuli associated with drug exposure can modulate various effects of drugs, but little is known about their role in relapse to drug seeking. Using a renewal procedure, the authors report that drug-associated contextual stimuli play a critical role in relapse to drug-seeking previously maintained by a heroin-cocaine mixture (speedball). Rats were trained to self-administer speedball, after which drug-reinforced behavior was extinguished over 20 days in the self-administration context or in a different context. On the test day, rats exposed to the drug-associated context, after extinction in a different context, reliably renewed drug seeking. The authors suggest that the renewal procedure can be used to study mechanisms underlying relapse to drug seeking elicited by drug-associated contextual stimuli.

AN - 71504393; 11878265 AB - Military personnel are at significant risk for potentially lethal myeloablative injury secondary to nuclear accident, nuclear attack, or chemical weapons attack. In an attempt to develop culture conditions in which hematopoietic stem cells might be rescued from the effects of radiation, we irradiated (1,000 cGy split dose) 6-week-old C57BL/6 (Ly 5.1) and syngeneic C57BL/6 (Ly 5.2) mice and tested whether bone marrow mononuclear cells (MNCs) harvested postirradiation could be rescued via coculture in porcine microvascular endothelial cell (PMVEC) monolayers. We found that a subpopulation of bone marrow MNCs exposed to 1,000 cGy could be maintained and expanded over 10 days in a PMVEC culture (3.8-fold expansion), whereas liquid suspension culture did not maintain a significant number of hematopoietic cells postirradiation. Colony-forming assays demonstrated that murine MNCs exposed to 1,000 cGy did not give rise to granulocyte/macrophage colony-forming units (CFU-GM), erythroid burst-forming units (BFU-e), or CFU-Mix in 14-day cultures, whereas irradiated MNCs that were subsequently cultured in PMVEC-generated CFU-GM, BFU-e, and CFU-Mix at cloning efficiencies of 1.3%, 0.2%, and 0.2%, respectively. In survival studies, we found that 78% of mice that were irradiated and then transplanted with irradiated/PMVEC-expanded MNCs were alive at day 50, compared with 18% of irradiated control mice (p < 0.05). We also observed that mice transplanted with irradiated/PMVEC-expanded MNCs showed complete hematologic recovery. At 8 weeks post-transplant, we found evidence of Ly 5.1 donor cells in both the bone marrow and the spleen of the transplanted animals, but the levels of engraftment were low (range, 0-5.1%; mean, 1.9%). These results demonstrate that a subpopulation of bone marrow stem cells are capable of surviving the effects of high-dose radiation if these cells are placed in coculture with endothelial cell monolayers.

AN - 71502438; 11885686 AB - Attempts to develop drugs, specific for cancer cells, are dealt here according to the intended cell-target. While many target specific drugs were developed, they reach only moderate successes in clinics for reasons, such as, delivery problem, lack of in vivo efficacy or toxicity. However, recent efforts focusing on the diversity of tyrosine kinases, participating in cell-signal transduction, brought fruit. The firs such drug, Givec, approved by the USFDA recently, is used in clinics with great success to threat CML. The drug inhibits tyrosin kinase of bcr-abl, c-abl and v-abl. Work is progressing on other tyrosin kinase inhibitors and on other type of specific cancer cell signal protein inhibitors. These efforts are hoped to yield better cures for cancer in the near future.

AN - 71500063; 11883597 AB - The sunscreen agent 2-phenylbenzimidazole-5-sulfonic acid (PBSA) and its parent 2-phenylbenzimidazole (PBI) cause DNA photodamage via both Type-I and Type-II mechanisms when UVB irradiated. We have studied the photophysical and photochemical properties of these compounds and their ability to photogenerate reactive oxygen species including free radicals. PBI and PBSA exhibit both oxidizing and reducing properties in their excited state. The absorption and fluorescence properties of PBSA depend strongly upon pH, and hence the photochemistry of PBSA was studied in both neutral and alkaline solutions. PBSA showed strong oxidizing properties when UV irradiated in neutral aqueous solution (pH 7.4) in the presence of cysteine, glutathione and azide, as evidenced by the detection of the corresponding S-cysteinyl, glutathiyl and azidyl radicals with the aid of the spin trap, 5,5-dimethyl-1-pyrroline N-oxide (DMPO). However, when an aqueous anaerobic solution (pH 10) of PBSA and either nitromethane (NM) or 4-nitrobenzoic acid (4-NBA) were irradiated, the corresponding nitro anion radicals were observed. This finding suggests that both NM and 4-NBA are reduced by direct electron transfer from the excited state PBSA. During UV irradiation of an aerobic solution of PBSA, O2*- and *OH radical were generated and trapped by DMPO. Further, PBI (in ethanol) and PBSA (in ethylene glycol : water 2: 1 mixture) showed low temperature (77 K) phosphorescence (lambdamax = 443, 476 and 509 nm) and also an electron paramagnetic resonance half-field transition (deltaMs = +/-2), which is evidence for a triplet state. This triplet produced singlet oxygen (1O2) with quantum yields 0.07 and 0.04 in MeCN for PBI and PBSA, respectively. These studies demonstrate that UV irradiation of PBSA and PBI generates a variety of free radicals and active oxygen species that may be involved in the photodamage of DNA.

AN - 71499529; 11873496 AB - Using a human myeloid tumor cell line (ML-1), we detected induction of mRNA expression of several stress-responsive genes by doses of gamma rays as low as 2 cGy. For instance, the dose response for induction of CIP1/WAF1 and GADD45 appears to be linear over the range of 2 to 50 cGy and shows no evidence of a threshold for induction. Although 2 and 5 cGy exposures did not result in any detectable reduction in cloning efficiency nor in increased apoptosis in ML-1 cells, these exposures did produce a brief cell-cycle delay. We also used fluorescent cDNA microarray hybridization to investigate transcriptional stress responses following low doses of gamma rays and to identify additional radiation-responsive genes for inclusion in a stress-specific microarray we are developing. These studies provide insight into the molecular responses to physiologically relevant doses, which cannot necessarily be extrapolated from high-dose studies. The use of high throughput arrays will allow the identification of multiple stress-responsive genes that are radiation inducible in a variety of cell types and tissues. The expectation is that transcriptional stress responses will provide a molecular approach to monitoring for radiation exposure and detecting interindividual differences.

AN - 71497399; 11873532 AB - The purpose of this study was to test a model of exposure to environmental tobacco smoke (ETS) in military women and their children. The convenience sample consisted of 238 women, 81 smokers and 157 nonsmokers, with a mean age of 37 years (SD = 9.9). Participants were either on active duty or were reservists and/or military dependents. Model constructs, some of which were adapted from the transtheoretical model of behavior change, measured personal and situational factors, pros and cons of ETS exposure, self-efficacy to resist ETS, mother's expectation for child's ETS exposure, and mother's self-efficacy to reduce child's ETS exposure. The mediating variable was the mother's daily ETS exposure, and the outcome variable was the child's daily ETS exposure. The trimmed model showed that 32% of the variance in mother's daily exposure (mediating variable) was accounted for by living with a smoker, having high ETS "pros" (as opposed to ETS "cons"), having less self-efficacy to resist ETS, and having greater self-efficacy to reduce the child's exposure. There was a significant, positive relationship (r = 0.51, p = 0.01) between the mother's and child's daily ETS exposure (outcome variable).

AN - 71495241; 11873514 AB - Selective protection of normal tissues from the damaging effects of ionizing radiation is an important objective in cancer treatment research. Likewise, radioprotective agents may be useful in protecting the human population in the event of radiation-related accidents or military conflicts. Over the past decade, we have identified stable nitroxide compounds as a unique class of antioxidants with demonstrated radioprotective properties. We have shown that nitroxides at nontoxic concentrations are effective as in vitro and in vivo antioxidants when oxidation is induced by superoxide, hydrogen peroxide, organic hydroperoxides, ionizing radiation, or specific DNA-damaging anticancer agents. Studies have shown that nitroxides protect against radiation-induced DNA damage, chromosome aberrations, mutation induction, cell killing, and lethality in mice that receive whole-body irradiation. Whether these agents provide radioprotection for low-level radiation doses remains to be determined.

AN - 71493465; 11833864 AB - This study was aimed to clarify phase angle between sleep propensity and the circadian pacemaker in patients with non-24-hour sleep-wake syndrome (Non-24). A case-control study was underaken. Sighted patient with Non-24 (4 males and 1 female, aged 16 to 39 y), and sex- and age-matched healthy controls (12 males and 3 females, aged 19 to 35 y) participated the study. MEASUREMENT AND INTERVENTION: Following an actigraphic assessment of the sleep-wake cycle in their homes, the participants entered an ultra-short sleep-wake schedule together with simultaneous measurement of dim light melatonin rhythm after 24-hour sleep deprivation. The period of the sleep-wake cycle observed at home was longer in the Non-24 patients (25.12 hours) than in the controls (24.02 hours, p<0.0001). The interval from sleep propensity (SP) onset to the melatonin midpoint (MLmid) was significantly shorter in the Non-24 patients than in the controls. The interval from the MLmid to the SP offset was significantly longer in the Non-24 patients than in the controls. It was postulated that Non-24 sufferers' delayed SP onset relative to the circadian pacemaker may accelerate the light-induced phase-delay, leading to sleep-wake cycle that is longer than 24 hours.

AN - 71487631; 11870753 AB - Tamoxifen (TAM), an antiestrogen, has been approved for use by women at risk for developing hormone-dependent breast cancer. Administration of TAM to pregnant CD-1 mice apparently results in reproductive tract toxicity in female offspring. However, there is little or no data describing potential TAM-induced fetal toxicity to women who may become pregnant while receiving prophylactic TAM treatment. In support of the National Toxicology Program's characterization of reproductive and developmental effects of TAM, the present work describes a capillary electrophoresis (CE)-based analytical technique used for detection of TAM and two major metabolites, N-desmethyltamoxifen (DMT), and 4-hydroxytamoxifen (4-HT) in CD-1 mouse fetal tissue. TAM-derived material was extracted from CD-1 mouse fetuses 2-12 h following TAM administration (100 mg/kg) to dams on gestation day 16. The presence of TAM, DMT, and 4-HT was confirmed in the solvent extracts by nonaqueous CE. The limit of detection of TAM by UV absorption was approximately 675 amol at a signal-to-noise ratio of 2:1. This work demonstrates both transplacental transport of TAM in CD-1 mice and a sensitive analytical technique for detecting low concentrations of TAM and similar compounds in biological tissues.

AN - 71487394; 11876753 AB - Treatment with the immunosuppressive drugs cyclosporin and tacrolimus, the mainstays of anti-graft rejection and autoimmune disease therapy, is limited by their hepato- and nephrotoxicity. The metabolic conversion of these compounds to more easily excretable products is catalysed mainly by hepatic cytochrome P4503A4 (CYP3A4) but also involves extrahepatic CYP3A5 and other P450 forms. We set out to study whether or not exposure to cyclosporin and FK506 in children undergoing organ transplantation leads to formation of autoantibodies against P450s. Immunoblotting analysis revealed anti-CYP reactivity in 16% of children on CyA for anti-graft rejection or treatment of nephrosis (n = 67), 31% of kidney transplant patients switched from CyA to FK506 (n = 16), and 21% of kidney and or liver transplant patients on FK506 (n = 14). In contrast, the frequency of reactive immunoblots was only 8.5% among the normal paediatric controls (n = 25) and 7% among adult kidney transplant patients on CyA or FK506 (n = 30). The CYP2C9+ sera were able to immunoprecipitate in vitro translated CYP2C9 and the immunoblot reactivity showed striking correlation to peaks in the age at onset of drug exposure. Sera were isoform selective as evidenced from Western blotting using human liver microsomes and heterologously expressed human P450s. These findings suggest that anti-cytochrome P450 autoantibodies, identified on the basis of their specific binding in immunoblots, are significantly increased among children on immunosuppressive drugs and in some cases are associated with drug toxicity and organ rejection.

AN - 71477974; 11858627 AB - Alcoholism is one of the most common psychiatric disorders with a prevalence of 8 to 14 percent. This heritable disease is frequently accompanied by other substance abuse disorders (particularly nicotine), anxiety and mood disorders, and antisocial personality disorder. Although associated with considerable morbidity and mortality, alcoholism often goes unrecognized in a clinical or primary health care setting. Several brief screening instruments are available to quickly identify problem drinking, often a pre-alcoholism condition. Problem drinking can be successfully treated with brief intervention by primary care physicians. Alcohol addiction is a lifelong disease with a relapsing, remitting course. Because of the potentially serious implications of the diagnosis, assessment for alcoholism should be detailed. Alcoholism is treated by a variety of psychosocial methods with or without newly developed pharmacotherapies that improve relapse rates. Screening for problem drinking and alcoholism needs to become an integral part of the routine health screening questionnaire for adolescents and all adults, particularly women of child-bearing age, because of the risk of fetal alcohol syndrome.

AN - 71472201; 11813213 AB - Numerous studies have been carried out to evaluate the association between lung cancer and occupational asbestos exposure. However, the effects of timing of exposure have not been analyzed thoroughly. Two German case-control studies with data on occupational asbestos exposure histories have been pooled. Duration of work in potentially asbestos exposed jobs and two derived weighted exposure measures are analyzed together with time since last exposure. A spline function is used to model the effect of time since exposure. The odds ratios (OR) and corresponding 95% confidence intervals were 1.8 (1.2, 2.7) and 2.4 (1.7, 3.4) for subjects having worked for 3 to 7 years and 8 or more years, respectively, in a job with potential asbestos exposure compared to never-exposed. Based on an evaluation of time since last exposure, the OR decreased significantly to about one-half after more than 20 years since exposure ceased. Using a spline function, applied to workers' complete exposure histories, the effect of an increment of exposure is greatest 10-15 years after that exposure was received. In contrast to previous indications, the risk of lung cancer increases soon after asbestos exposure, with its maximum effect from 10 to 15 years after the exposure was received.

AN - 71467352; 11853704 AB - Niuhuang is a commonly used Chinese traditional medicine with immunoregulatory and anti-inflammatory properties. Deoxycholic acid (DCA) is a major active constituent of Niuhuang. The reaction of human leukocytes to chemoattractants is an important part of the host immune response and also plays a crucial role in the development of inflammation. We, therefore, investigated the in vitro effects of DCA on human monocyte and neutrophil responses to classic chemoattractants [fMet-Leu-Phe (fMLP), complement fraction 5a (C5a)], CC chemokine [monocyte chemoattractant protein-1 (MCP-1/CCL2)], and/or CXC chemokines [stromal cell-derived factor-1 (SDF-1alpha/CXCL12), interleukin-8 (IL-8/CXCL8)]. The results showed that DCA significantly inhibited fMLP-induced monocyte and neutrophil chemotaxis and calcium mobilization, and also blocked the binding of [3H]fMLP and anti-formyl peptide receptor (FPR) monoclonal antibodies (mAb) to the cells. The inhibitory effects of DCA on calcium mobilization and anti-FPR-mAb binding to the receptor could be abrogated by washing DCA out of the cell suspension, suggesting that DCA blocked fMLP receptors via a steric hindrance mechanism, not via receptor internalization. DCA had no significant inhibitory effects on MCP-1-, SDF-1alpha-, or C5a-induced monocyte function, or C5a- or IL-8-induced neutrophil function. Taken together, our experimental results suggest that blockade of fMLP receptors may contribute to the anti-inflammatory effects of traditional medicine containing DCA.

AN - 71463937; 11847201 AB - Several vasoconstrictor agents can regulate the phosphorylation status of the Na(+)-K(+) ATPase (NKA). We have recently demonstrated that mammalian tissues contain an endogenous bufadienolide, digitalis-like alpha(1)-NKA-selective ligand, marinobufagenin (MBG). Protein kinase C induces phosphorylation of the alpha(1)-NKA isoform, the major isoform in vascular smooth muscle, kidney, and heart cells. We hypothesized that protein kinase C-induced phosphorylation of NKA can potentiate the effect of endogenous digitalis-like ligands, and that such potentiation can occur in an NKA isoform-specific fashion. A protein kinase C activator, phorbol 12,13-diacetate (PDA, 50 nmol/L), induced phosphorylation of the alpha1-NKA from human mesenteric artery (HMA) sarcolemma and rat kidney but not that of the alpha(3)-NKA from rat fetal brain. In HMA sarcolemma, which predominantly contains alpha(1)-NKA, PDA (50 nmol/L) potentiated the NKA-inhibitory effect of MBG at the level of high-affinity binding sites (0.05 +/- 0.03 nmol/L versus 4.0 +/- 1.7 nmol/L, P<0.05). In contrast, PDA did not affect the NKA inhibition by ouabain, an alpha(3)-NKA ligand. In isolated endothelium-denuded HMA artery rings, 50 nmol/L PDA potentiated the MBG-induced vasoconstriction (EC(50), 17 +/- 6 nmol/L versus 150 +/- 40 nmol/L; P<0.01). Our results suggest that alpha(1)-isoform-specific NKA inhibition by the endogenous digitalis-like ligand, MBG, is substantially enhanced via NKA phosphorylation by protein kinase C. Thus, an interaction of protein kinase C-dependent phosphorylation and MBG on NKA activity may underlie the synergistic vasoactive effects of MBG and other endogenous vasoconstrictors in hypertension.

AN - 71458607; 11841566 AB - The therapeutic mechanisms of lithium for treating bipolar mood disorder remain poorly understood. Recent studies demonstrate that lithium has neuroprotective actions against a variety of insults. Here, we studied neuroprotective effects of lithium against excitotoxicity in cultured cerebral cortical neurons. Glutamate-induced excitotoxicity in cortical neurons was exclusively mediated by NMDA receptors. Pre-treatment of cortical neurons with LiCl time-dependently suppressed excitotoxicity with maximal protection after 6 days of pre-treatment. Significant protection was observed at the therapeutic and subtherapeutic concentration of 0.2-1.6 mm LiCl with almost complete protection at 1 mM. Neuroprotection was also elicited by valproate, another major mood-stabilizer. The neuroprotective effects of lithium coincided with inhibition of NMDA receptor-mediated calcium influx. Lithium pre-treatment did not alter total protein levels of NR1, NR2A and NR2B subunits of NMDA receptors. However, it did markedly reduce the level of NR2B phosphorylation at Tyr1472 and this was temporally associated with its neuroprotective effect. Because NR2B tyrosine phosphorylation has been positively correlated with NMDA receptor-mediated synaptic activity and excitotoxicity, the suppression of NR2B phosphorylation by lithium is likely to result in the inactivation of NMDA receptors and contributes to neuroprotection against excitotoxicity. This action could also be relevant to its clinical efficacy for bipolar patients.

AN - 71452269; 11842388 AB - Accumulating evidence suggests that the ability to activate apoptotic pathways may be an important determinant of chemotherapy sensitivity and presents a potentially important new therapeutic strategy. Monoclonal antibodies against the CD20 antigen directly induce apoptosis and may serve to modulate the threshold for chemotherapy-induced apoptosis. Rituximab (Rituxan; Genentech, Inc, South San Francisco, CA, and IDEC Pharmaceuticals, San Diego, CA), a monoclonal antibody against CD20, was combined with dose-adjusted EPOCH (infusional etoposide/vincristine/doxorubicin/bolus cyclophosphamide/prednisone) chemotherapy and tested in 38 untreated or relapsed poor-prognosis aggressive lymphomas. Twenty-three patients were untreated. Of these patients, all had large B-cell histologies, a median age of 52 years, Eastern Cooperative Oncology Group performance status > or = 2 in 30%, and high-intermediate or high International Prognostic Index scores in 61%. Fifteen patients had relapsed or refractory lymphomas. These patients had received a median of two (range, one to four) prior regimens, 67% had aggressive histologies, and 60% had high-intermediate or high International Prognostic Index scores. Complete remissions were achieved in 85% and 64% of untreated and previously treated patients, respectively; additionally 42% of patients with disease refractory before therapy achieved complete remission. At a median follow-up of 12 months, progression-free and overall survival in the previously untreated group was 85% and 79%, respectively, and no patient in complete remission has relapsed. These results suggest that rituximab may modulate the sensitivity of B-cell lymphomas to chemotherapy.

Report of a workshop sponsored by the Radiation Research Program, National Cancer Institute, Bethesda, Maryland, September 6-8, 2000. AN - 71451974; 11835685 AB - Late effects that develop in normal tissues adjacent to the tumor site in the months to years after radiotherapy can reduce the quality of life of cancer survivors. They can be dose-limiting and debilitating or life-threatening. There is now evidence that some late effects may be preventable or partially reversible. A workshop, "Modifying Normal Tissue Damage Postirradiation", was sponsored by the Radiation Research Program of the National Cancer Institute to identify the current status of and research needs and opportunities in this area. Mechanistic, genetic and physiological studies of the development of late effects are needed and will provide a rational basis for development of treatments. Interdisciplinary teams will be needed to carry out this research, including pathologists, physiologists, geneticists, molecular biologists, experts in functional imaging, wound healing, burn injury, molecular biology, and medical oncology, in addition to radiation biologists, physicists and oncologists. The participants emphasized the need for developing and choosing appropriate models, and for radiation dose-response studies to determine whether interventions remain effective at the radiation doses used clinically. Both preclinical and clinical studies require long-term follow-up, and easier-to-use, more objective clinical scoring systems must be developed and standardized. New developments in biomedical imaging should provide useful tools in all these endeavors. The ultimate goals are to improve the quality of life and efficacy of treatment for cancer patients treated with radiotherapy.

AN - 71445702; 11799161 AB - An important, unresolved issue in mononegavirus biology is whether or not transcription is initiated by the same promoter as RNA replication. In this study, residues important for respiratory syncytial virus (RSV) transcription and RNA replication were identified by subjecting the first 26 nucleotides of genome RNA to saturation mutagenesis. This analysis was performed using a genome analog that allowed transcription and RNA replication to be dissociated from each other and monitored as independent events in an intracellular assay. This analysis showed that nucleotides 3C, 5C, 8U, 9U, 10U, and 11U were important for transcription and RNA replication. Additional nucleotides (1U, 2G, 6U, and 7U) were important for RNA replication, but not transcription. At position 4, G versus C or U augmented transcription and decreased replication, showing that the naturally occurring assignments in the genomic (4G) and antigenomic (4U) promoters are optimal for transcription and RNA replication, respectively. These data show that RSV transcription and RNA replication each involve a cis-acting signal at the very 3" end of the genome. This signal appears to contain a minimum, common element that functions in both transcription and RNA replication, defined by those substitutions that had similar effects on the two processes. Apart from these common nucleotides, other positions were involved in RNA replication but not transcription or had different effects on the two processes. This indicates that the promoters for transcription and replication involve overlapping sets of nucleotides at the very 3" end of the genome and provides evidence that the nucleotide preferences for the two processes are not identical.

AN - 71440116; 11813246 AB - The glutamate uptake inhibitor L-trans-2,4-pyrrolidine-dicarboxylate (PDC) induces glutamate accumulation and neuronal damage in cultured cells. We have used dissociated cortical cells in culture to study whether the toxicity induced by inhibiting glutamate uptake with PDC could be blocked by the simultaneous inhibition of gamma-aminobutyric acid (GABA) uptake, because both types of transporters are affected during an ischemic event. After 6 hr of exposure to 100 microM GABA or to four different GABA uptake inhibitors, the concentration of extracellular GABA was augmented from the basal 2 microM value to about 25 microM and 5 microM, respectively. These increases, however, did not result in protection against the neuronal damage induced by the accumulation of extracellular glutamate because of the simultaneous exposure to PDC. In contrast, when 100 microM GABA and an inhibitor of GABA uptake were added, after 6 hr the concentrations of GABA reached 50 microM, and neurons were protected from PDC-induced toxicity. The addition of the GABA(A) and GABA(B) receptor agonists muscimol and baclofen also partially protected against PDC-induced damage. The results suggest that the excitotoxic damage resulting from chronic gradual elevation of extracellular glutamate may be prevented by high concentrations of extracellular GABA, an effect mediated by activation of GABA(A) and GABA(B) receptors.

AN - 71437343; 11826108 AB - Increasing evidence has suggested an important role for environmental factors such as exposure to pesticides in the pathogenesis of Parkinson's disease. In experimental animals the exposure to a common herbicide, rotenone, induces features of parkinsonism; mechanistically, rotenone-induced destruction of dopaminergic neurons has been attributed to its inhibition of the activity of neuronal mitochondrial complex I. However, the role of microglia, the resident brain immune cells in rotenone-induced neurodegeneration, has not been reported. Using primary neuron-enriched and neuron/glia cultures from the rat mesencephalon, we discovered an extraordinary feature for rotenone-induced degeneration of cultured dopaminergic neurons. Although little neurotoxicity was detected in neuron-enriched cultures after treatment for 8 d with up to 20 nm rotenone, significant and selective dopaminergic neurodegeneration was observed in neuron/glia cultures 2 d after treatment with 20 nm rotenone or 8 d after treatment with 1 nm rotenone. The greatly enhanced neurodegenerative ability of rotenone was attributed to the presence of glia, especially microglia, because the addition of microglia to neuron-enriched cultures markedly increased their susceptibility to rotenone. Mechanistically, rotenone stimulated the release of superoxide from microglia that was attenuated by inhibitors of NADPH oxidase. Furthermore, inhibition of NADPH oxidase or scavenging of superoxide significantly reduced the rotenone-induced neurotoxicity. This is the first report demonstrating that microglia play a pivotal role in rotenone-induced degeneration of dopaminergic neurons. The results of this study should advance our understanding of the mechanism of action for pesticides in the pathogenesis of Parkinson's disease.

AN - 71436759; 11826419 AB - Interferon alfa (IFN-alpha) is currently the only well-established therapy for viral hepatitis. However, its effectiveness is much reduced (<10%) in alcoholic patients. The mechanism underlying this resistance is not fully understood. In this study, we examined the expression of IFN-alpha signaling components and its inhibitory factors in 9 alcoholic liver disease (ALD) and 8 healthy control liver tissues. In comparison with normal control livers, expression of IFN-beta, IFN-alpha receptor 1/2, Jak1, and Tyk2 remained unchanged in ALD livers, whereas expression of IFN-alpha, signal transducer and activator of transcription factor 1 (STAT1), and p48 were up-regulated and expression of STAT2 was down-regulated. Expression of antiviral MxA a karyophilic 75 kd protein induced by IFN in mouse cells carrying the influenza virus resistance allele Mx(+) and 2'-5' oligoadenylate synthetase (OAS) proteins was not regulated, whereas expression of double-stranded RNA-activated protein kinase (PKR) was decreased by 55% in ALD livers. Three families of inhibitory factors for the JAK-STAT signaling pathway were examined in ALD livers. Members of the suppressor of cytokine signaling (SOCS) family, including SOCS 1, 2, 3, and CIS, and the protein tyrosine phosphatases, including Shp-1, Shp-2, and CD45, were not up-regulated in ALD livers, whereas the phosphorylation of and protein levels of p42/44 mitogen-activated protein kinase (p42/44MAP kinase) were increased about 3.9- and 3.2-fold in ALD livers in comparison with normal control livers, respectively. In conclusion, these findings suggest that chronic alcohol consumption down-regulates STAT2 and PKR, but up-regulates p42/44 mitogen-activated protein kinase (p42/44MAP kinase), which may cause down-regulation of IFN-alpha signaling in the liver of ALD patients.

AN - 71432963; 11826121 AB - Neurons of adult brain are able to remodel their synaptic connections in response to various stimuli. Modifications of the peridendritic environment, including the extracellular matrix, are likely to play a role during synapse remodeling. Proteolytic disassembly of ECM is a complex process using the regulated actions of specific extracellular proteinases. One of best-characterized families of matrix-modifying enzymes is the matrix metalloproteinase (MMP) family. Here, we describe changes in the expression and function of two well known MMPs, MMP-9 and MMP-2, in adult rat brain before and after systemic administration of the glutamate receptor agonist kainate. Kainate application results in enhanced synaptic transmission and seizures followed by selective tissue remodeling, primarily in hippocampal dentate gyrus. MMP-9 but not MMP-2 was highly expressed by neurons in normal adult rat brain. MMP-9 protein was localized in neuronal cell bodies and dendrites. Kainate upregulated the level of MMP-9 mRNA and protein within hours after drug administration. This was followed several hours later by MMP-9 enzymatic activation. Within hippocampus, MMP-9 mRNA and activity were increased selectively in dentate gyrus, including its dendritic layer. In addition, MMP-9 mRNA levels decreased in areas undergoing neuronal cell loss. This unique spatiotemporal pattern of MMP-9 expression suggests its involvement in activity-dependent remodeling of dendritic architecture with possible effects on synaptic physiology.

AN - 71430674; 11826401 AB - Mechanistic study of idiosyncratic drug-induced hepatitis (DIH) continues to be a challenging problem because of the lack of animal models. The inability to produce this type of hepatotoxicity in animals, and its relative rarity in humans, may be linked to the production of anti-inflammatory factors that prevent drug-protein adducts from causing liver injury by immune and nonimmune mechanisms. We tested this hypothesis by using a model of acetaminophen (APAP)-induced liver injury in mice. After APAP treatment, a significant increase was observed in serum levels of interleukin (IL)-4, IL-10, and IL-13, cytokines that regulate inflammatory mediator production and cell-mediated autoimmunity. When IL-10 knockout (KO) mice were treated with APAP, most of these mice died within 24 to 48 hours from liver injury. This increased susceptibility to APAP-induced liver injury appeared to correlate with an elevated expression of liver proinflammatory cytokines, tumor necrosis factor (TNF)-alpha, and IL-1, as well as inducible nitric oxide synthase (iNOS). In this regard, mice lacking both IL-10 and iNOS genes were protected from APAP-induced liver injury and lethality when compared with IL-10 KO mice. All strains, including wild-type animals, generated similar amounts of liver APAP-protein adducts, indicating that the increased susceptibility of IL-10 KO mice to APAP hepatotoxicity was not caused by an enhanced formation of APAP-protein adducts. In conclusion, these findings suggest that an important feature of the normal response to drug-induced liver injury may be the increased expression of anti-inflammatory factors such as IL-10. Certain polymorphisms of these factors may have a role in determining the susceptibility of individuals to idiosyncratic DIH. JF - Hepatology (Baltimore, Md.)

AN - 71429541; 11826136 AB - Intravenous heroin self-administration in trained rats was accompanied by robust brain hyperthermia (+2.0-2.5 degrees C); parallel changes were found in the dorsal and ventral striatum, mediodorsal thalamus, and deep temporal muscle. Temperature began to increase at variable latency after a signal of drug availability, increased reliably (approximately 0.4 degrees C) before the first lever press for heroin, increased further (approximately 1.2 degrees C) after the first heroin injection, and rose more slowly after the second and third injections to stabilize at an elevated plateau (39-40 degrees C) for the remainder of the session. Brain and body temperature declined slowly when drug self-administration was terminated; naloxone precipitated a much more rapid decrease to baseline levels. Changes in temperature were similar across repeated daily sessions, except for the increase associated with the first self-administration of each session, which had progressively shorter latency and greater acceleration. Despite consistent biphasic fluctuations in movement activity associated with heroin self-administrations (gradual increase preceding the lever press, followed by an abrupt hypodynamia after drug infusion), mean brain temperature was very stable at an elevated plateau. Only mean muscle temperature showed evidence of biphasic fluctuations (+/-0.2 degrees C) that were time locked to and correlated with lever pressing and associated movements. Drug- and behavior-related changes in brain temperature thus appear to reflect some form of neuronal activation, and, because temperature is a factor capable of affecting numerous neural functions, it may be an important variable in the control of behavior by drugs of abuse.

AN - 71423050; 11805730 AB - Despite its known teratogenic effects, thalidomide has been used to treat a variety of diseases ranging from alleviation of autoimmune disorders to prevention of metastasis of cancers. The exact method of action of thalidomide and its derivatives is still under investigation. Thalidomide undergoes very little metabolism by the cytochrome P 450 system in vitro, but at least two hydroxylated metabolites have been found in humans. The two metabolites are 5-hydroxythalidomide, formed by hydroxylation of the phthalimide ring, possibly via arene oxides, and 5'-hydroxythalidomide, formed by hydroxylation of the glutarimide ring, leading to diastereomeric products. These two metabolites, along with another minor metabolite of thalidomide, were tested in a rat aortic ring assay, a human saphenous vein model, and a tube formation assay to assess the metabolite's ability to inhibit angiogenesis. Of the metabolites tested, only 5'-OH-thalidomide showed biologic activity in the rat aortic ring assay, and none of the metabolites showed activity in the human model. The studies with thalidomide and thalidomide metabolites underline the difficulty and complexity of trying to isolate and evaluate a single biologically active agent. These studies, however, do suggest that at least one metabolite, 5'-OH-thalidomide, has moderate antiangiogenic activity at high concentrations. Unfortunately, because of the lack of observed activity of 5'-OH-thalidomide in the human saphenous vein assay, it remains unclear whether there is species specificity for the activity of this metabolite.

AN - 71422489; 11811972 AB - High-performance liquid (HPLC) and thin-layer (TLC) chromatographic methods for the detection and quantification of diazeniumdiolates are described. The HPLC determinations were made using a Rocket Platinum NH2 column (7 x 53 mm, 100-A pore size, 3-microm particle size), under isocratic conditions with mixtures of acetonitrile, methanol, and water containing 0.1% diethylamine (v/v), at a flow rate of 2.5 ml/min, a column temperature of 22 degrees C, and UV detection at 250 nm. The TLC determinations were similarly made using Merck NH2 F254S precoated glass plates (approximately 2 x 5 cm, 5-microm particle size, 0.2-mm layer thickness) with mixtures of acetonitrile, methanol, and water containing 0.1% diethylamine (v/v). Preexisting traces of carcinogenic nitrosamines were detected in some samples of diazeniumdiolates. The methods provide a more efficient means of characterizing the purity of diazeniumdiolate samples prepared for use in biomedical applications than older procedures which rely on differential absorbance measurements at 250 and 350 nm, respectively.

AN - 71422484; 11802212 AB - The involvement of PRL in regulating monocyte/macrophage functions is suggested by the presence of PRL-Rs in these cells. Here, we show that PRL, though it failed to activate mouse peritoneal resident macrophages (RMs), acted as a second signal and activated mouse peritoneal inflammatory macrophages (EMs) to a tumoricidal state. The cytotoxicity of mouse tumor-associated macrophages (TAMs) isolated at day 1 of tumor (Ehrlich ascites carcinoma, EAC) growth was enhanced by PRL. However, with progression of tumor growth, TAMs became nonresponsive to the hormone. PRL-induced killing of P815 target cells by EMs and TAMs was independent of TNF but correlated with the hormone-induced augmentation of NO2(-) and O2(-) release in these macrophages. Administration of PRL in vivo inhibited EAC growth and augmented NO2(-) release by TAMs. PRL synergized with the TH1 cytokine IFN-gamma, a known activator of macrophages, in inducing tumor killing and release of NO2(-) from EMs and TAMs. The hormone might activate macrophages at least partially, through the release of IFN-gamma as anti-IFN-gamma blocked IFN-gamma- as well as PRL-induced cytotoxicity in EMs. The TH2 cytokine IL-4 suppressed PRL-induced activation of macrophages. PRL induced release of IL-12 from EMs also, which suggested that the hormone might drive the TH1 response through IL-12. Our observations further suggest that PRL alone and in synergy with IFN-gamma, released through induction of IL-12, may generate tumoricidal macrophages and thus regulate the antitumor immune response of tumor hosts.

AN - 71419298; 11805731 AB - Irinotecan is a prodrug that is hydrolyzed by carboxylesterase in vivo to form an active metabolite SN-38. SN-38 is further conjugated and detoxified by UDP-glucuronosyltransferase (UGT) to yield its beta-glucuronide (SN-38G). Although irinotecan is widely used, the drug causes unpredictably severe, occasionally fatal, toxicity of leukopenia or diarrhea. Interindividual variation of sensitivity to irinotecan is related to large variations of biotransformation of the active metabolite SN-38, some of which would be caused by genetic polymorphism of UGT1A1, an isozyme responsible for the SN-38 glucuronidation. As a surrogate for the UGT activity, the polymorphic frequency distribution of the area under the concentration-time curve (AUC) ratios of SN-38 to SN-38G (AUC(SN-38)/AUC(SN-38G)) using pooled pharmacokinetic data from four independent study groups in Japan was explored. The data from 100 cancer patients was analyzed, including 14 who were genotyped for UGT1A1 gene in the previous studies. The median ratios of AUC(SN-38)/AUC(SN-38G) was 0.40 (interquartile range, 0.30 to 0.55; range, 0.09 to 2.32). Frequency distribution of the AUC (SN-38)/AUC(SN-38G) was skewed to the right without bimodality and the patient population could not be segregated into discrete subgroups that differ in the UGT activity by the AUC ratios. The 4 subjects carrying UGT1A1*28 allele had values of the AUC(SN-38)/AUC(SN-38G) above the 75th percentile of the total population, suggesting a potential pharmacogenetic/pharmacokinetic relationship. Ordinary values with a median of 0.41 (interquartile range, 0.33 to 0.49) were obtained for the UGT1A1*6 heterozygous patient and the 9 UGT1A1*1 homozygous patients (the reference sequence). The large variation in the UGT activity being related to the genetic status would warrant pharmacogenetic-guided dosing of irinotecan.

AN - 71415197; 11796609 AB - The human pathogen Streptococcus pyogenes secretes many proteins to the cell wall and extracellular environment that contribute to virulence. Rgg regulates the expression of several exoproteins including a cysteine protease (SPE B), a nuclease (MF-1), a putative nuclease (MF-3), and autolysin. The functional heterogeneity of Rgg-regulated exoproteins and the lack of a conserved regulatory motif in the promoter regions of the genes suggested that Rgg interacts with additional regulatory networks to influence gene expression. DNA microarrays were used to test this hypothesis by comparing genomewide transcript profiles of S. pyogenes NZ131 and isogenic derivative NZ131 rgg during the exponential phase of growth. Transcripts of known and putative virulence-associated genes were more abundant in the rgg mutant, including emm, scpA, orfX, scl1, hasAB, slo, sagA, ska, speH, grab, mac, mf-1, and mf-3. Increased transcription of emm, scpA, and orfX in the rgg mutant was associated with increased production of the corresponding proteins. Differences in the expression of virulence-associated genes were associated with changes in the expression of several regulatory genes, including mga, sagA, csrRS, and fasBCA. The results show that Rgg influences the expression of multiple regulatory networks to coregulate virulence factor expression in S. pyogenes.

AN - 71411850; 11818294 AB - This study examined the association between unwanted sexual activity during childhood and risky behaviors among a sample of predominantly African American and Hispanic men. Data were obtained from baseline interviews completed by 2676 men enrolled in a multisite HIV prevention trial. Approximately 25% of the men reported unwanted or uninvited sexual activity before 13 years of age, with Hispanic men more likely than African American men to report unwanted sexual activity during childhood. Men with a history of unwanted sexual activity during childhood were more likely to report unwanted sexual activity since age 13, the buying and selling of sex, problems with alcohol, and drug use. Men who reported unwanted sexual activity during childhood also reported a significantly greater frequency of unprotected sexual acts and more partners. Among men at high risk for HIV infection, unwanted sexual activity during childhood is more widespread than previously described and can increase the risk of participating in harmful health practices during adulthood, including risky sexual behaviors.

AN - 71410348; 11717305 AB - MutL homologs belong to a family of proteins that share a conserved ATP binding site. We demonstrate that amino-terminal domains of the yeast MutL homologs Mlh1 and Pms1 required for DNA mismatch repair both possess independent, intrinsic ATPase activities. Amino acid substitutions in the conserved ATP binding sites concomitantly reduce ATP binding, ATP hydrolysis, and DNA mismatch repair in vivo. The ATPase activities are weak, consistent with the hypothesis that ATP binding is primarily responsible for modulating interactions with other MMR components. Three approaches, ATP hydrolysis assays, limited proteolysis protection, and equilibrium dialysis, provide evidence that the amino-terminal domain of Mlh1 binds ATP with >10-fold higher affinity than does the amino-terminal domain of Pms1. This is consistent with a model wherein ATP may first bind to Mlh1, resulting in events that permit ATP binding to Pms1 and later steps in DNA mismatch repair.

AN - 71409314; 11813240 AB - Cyclin-dependent kinase 5 (cdk5), in contrast to other members of the cyclin-dependent kinase family, is not activated by cyclins but instead is activated by complexing with neuron-specific activator molecules (p35, p39, and p67). The most effective activator of cdk5 both in vitro and in vivo is p35. We have taken a kinetic approach to study the interaction between p35, its various truncated forms, and cdk5 to understand better the mechanism of its activation. The cdk5 complexes formed with the truncated forms p25 and p21 produced similar maximum active kinase, whereas the cdk5 complexed with full-length p35 and a further truncated form spanning amino acid residues from 138 to 291, with approximate molecular weight of 16 kDa (p16), produced slightly less (80%) activation than p25. P16 was the smallest fragment of p35 that produced activation equal to or greater than that of full-length p35. By examination of further truncations of p16, we found that a small number of residues, 11 and 4 at the N- and C-termini, respectively, of p16, are essential for cdk5 activation. Further truncation, removing both essential N- and C-terminal domains, produces a peptide with markedly higher affinity for cdk5 compared with the peptides that retain either of these domains. Using these inactive truncated peptides as inhibitors, we examined the kinetics of activation. From these studies we conclude that activation involves at least three cdk5-interacting domains, one located at each end of p16 and at least one located in a central domain. The cdk5 activation process is slow: The second-order rate constant for p16 is about 1.2 microM(-1) hr(-1). On the basis of kinetic data, we suggest that cdk5 exists in two conformations. The inactive kinase conformation predominates in the absence of the activator. Activation occurs in two stages: a rapid and reversible interaction of cdk5 with its activator, which involves only one or two binding domains, followed by a slow stabilization of the active conformation as interaction with all three domains is achieved.

AN - 71408080; 11804682 AB - Cooking oil fumes have been suggested to increase the risk of lung cancer in Chinese women by exposing them to mutagenic substances. We investigated the association between lung cancer and locally made rapeseed and linseed oils in a population-based case-control study in Gansu Province, China. Two hundred and thirty-three incident, female lung cancer cases diagnosed from 1994-98 were identified. A control group of 459 women was selected from census lists and were frequency matched on age and prefecture. Interviewers obtained information on cooking practices and cooking oil use. The odds ratio (OR) for lung cancer associated with ever-use of rapeseed oil, alone or in combination with linseed oil, was 1.67 (95% CI 1.0-2.5), compared to use of linseed oil alone. ORs for stir-frying with either linseed or rapeseed oil 15-29, 30 and > or =31 times per month were 1.96,1.73, and 2.24, respectively (trend, P=0.03), relative to a lower frequency of stir-frying. Lung cancer risks also increased with total number of years cooking (trend, P<0.09).

AN - 71366429; 11773409 AB - We identified UIC-94003, a nonpeptidic human immunodeficiency virus (HIV) protease inhibitor (PI), containing 3(R),3a(S),6a(R)-bis-tetrahydrofuranyl urethane (bis-THF) and a sulfonamide isostere, which is extremely potent against a wide spectrum of HIV (50% inhibitory concentration, 0.0003 to 0.0005 microM). UIC-94003 was also potent against multi-PI-resistant HIV-1 strains isolated from patients who had no response to any existing antiviral regimens after having received a variety of antiviral agents (50% inhibitory concentration, 0.0005 to 0.0055 microM). Upon selection of HIV-1 in the presence of UIC-94003, mutants carrying a novel active-site mutation, A28S, in the presence of L10F, M46I, I50V, A71V, and N88D appeared. Modeling analysis revealed that the close contact of UIC-94003 with the main chains of the protease active-site amino acids (Asp29 and Asp30) differed from that of other PIs and may be important for its potency and wide-spectrum activity against a variety of drug-resistant HIV-1 variants. Thus, introduction of inhibitor interactions with the main chains of key amino acids and seeking a unique inhibitor-enzyme contact profile should provide a framework for developing novel PIs for treating patients harboring multi-PI-resistant HIV-1.

AN - 71358931; 11773385 AB - Reverse genetics was used to develop a two-component, trivalent live attenuated vaccine against human parainfluenza virus type 3 (HPIV3) and respiratory syncytial virus (RSV) subgroups A and B. The backbone for each of the two components of this vaccine was the attenuated recombinant bovine/human PIV3 (rB/HPIV3), a recombinant BPIV3 in which the bovine HN and F protective antigens are replaced by their HPIV3 counterparts (48). This chimera retains the well-characterized host range attenuation phenotype of BPIV3, which appears to be appropriate for immunization of young infants. The open reading frames (ORFs) for the G and F major protective antigens of RSV subgroup A and B were each placed under the control of PIV3 transcription signals and inserted individually or in homologous pairs as supernumerary genes in the promoter proximal position of rB/HPIV3. The level of replication of rB/HPIV3-RSV chimeric viruses in the respiratory tract of rhesus monkeys was similar to that of their parent virus rB/HPIV3, and each of the chimeras induced a robust immune response to both RSV and HPIV3. RSV-neutralizing antibody titers induced by rB/HPIV3-RSV chimeric viruses were equivalent to those induced by infection with wild-type RSV, and HPIV3-specific antibody responses were similar to, or slightly less than, after infection with the rB/HPIV3 vector itself. This study describes a novel vaccine strategy against RSV in which vaccine viruses with a common attenuated backbone, specifically rB/HPIV3 derivatives expressing the G and/or F major protective antigens of RSV subgroup A and of RSV subgroup B, are used to immunize by the intranasal route against RSV and HPIV3, which are the first and second most important viral agents of pediatric respiratory tract disease worldwide.

Less discussed is the fact that the safeguards one deems appropriate depend, in large part, on the model of research participation that one assumes. Therefore, to determine what safeguards are appropriate, it is necessary first to clarify the competing models of research participation. The ostensibly obscure debate over informed consent for research on stored biological samples is of particular interest in this regard because such research can involve varying subsets of the three central elements of research involvement. As a result, analysis of this debate provides an opportunity to identify the competing models of research participation. Based on this analysis, this paper describes a new model of research participation that is emerging, & considers its implications for clinical research. Adapted from the source document.

This need has been accentuated by the realization that the ability to conduct large placebo-controlled trials will be limited in the future. From the first use of magnetic resonance imaging (MRI) to study MS, the ability of this imaging technique to identify areas of the central nervous system damage by the disease process in MS has been impressive. Thus, the possibility that MRI could serve as a surrogate outcome measure in clinical trials in MS has been attractive. The use of MRI as a surrogate outcome measure has been examined by an international group of investigators with expertise in clinical aspects of MS, the use of MRI in MS, and in experimental therapeutics. The group agreed that MRI does not represent a validated surrogate in any clinical form of MS. It was also agreed, however, that MRI does provide a reflection of the underlying pathology in the disease, but no single MRI measurement in isolation was seen as sufficient to monitor disease. The use for multiple imaging techniques, especially new, emerging techniques that may better reflect the underlying pathology, was seen as particularly important in monitoring studies of patients with either secondary or primary progressive MS. The choice of MRI techniques used to monitor new therapies needs to be consistent with the proposed mechanisms of the new therapy and phase of the disease. It was also noted, however, that additional validation is required for nonconventional imaging techniques. Finally, the participants noted that clinical trials using MRI as a primary outcome measure may fail to fully identify the effects of the therapy on clinical measures and that the risk and cost-benefit ratio of the treatment might be unresolved. Thus, before MRI is used as a primary outcome measure, new approaches to trial design must be given careful consideration.

Here we review the limited but growing epidemiologic and experimental literature pertaining to the association between autoimmune diseases and occupational exposure to silica, solvents, pesticides, and ultraviolet radiation. The strongest associations (i.e., relative risks of 3.0 and higher) have been documented in investigations of silica dust and rheumatoid arthritis, lupus, scleroderma and glomerulonephritis. Weaker associations are seen, however, for solvent exposures (in scleroderma, undifferentiated connective tissue disease, and multiple sclerosis) and for farming or pesticide exposures (in rheumatoid arthritis). Experimental studies suggest two different effects of these exposures: an enhanced proinflammatory (TH1) response (e.g., TNF- alpha and IL-1 cytokine production with T cell activation), and increased apoptosis of lymphocytes leading to exposure to or modification of endogenous proteins and subsequent autoantibody formation. The former is a general mechanism that may be relevant across a spectrum of autoimmune diseases, whereas the latter may be a mechanism more specific to particular diseases (e.g., ultraviolet radiation, Ro autoantibodies, and lupus). Occupational exposures are important risk factors for some autoimmune diseases, but improved exposure assessment methods and better coordination between experimental/animal models and epidemiologic studies are needed to define these risks more precisely.

The Lyme disease spirochete, Borrelia burgdorferi, is transmitted by the slow-feeding ixodid tick Ixodes scapularis, whereas the relapsing fever spirochete, B. hermsii, is transmitted by Ornithodoros hermsi, a fast-feeding argasid tick. Lyme disease spirochetes are generally restricted to the midgut in unfed I. scapularis. When nymphal ticks feed, the bacteria pass through the hemocoel to the salivary glands and are transmitted to a new host in the saliva after 2 days. Relapsing fever spirochetes infect the midgut in unfed O. hermsi but persist in other sites including the salivary glands. Thus, relapsing, fever spirochetes are efficiently transmitted in saliva by these fast-feeding ticks within minutes of their attachment to a mammalian host. We describe how B. burgdorferi and B. hermsii change their outer surface during their alternating infections in ticks and mammals, which in turn suggests biological functions for a few surface-exposed lipoproteins.

AN - 18442877; 5419094 AB - There is a growing body of evidence demonstrating that exposure of cells to reactive oxygen species (ROS) leads to oxidative modification of nucleic acids, proteins, and lipids, and that such modifications can contribute to the development of a number of diseases and aging. This raises the question: If ROS are so damaging to cells, why have cells selected ROS to trigger activation of so many cell signaling pathways?

This retrospective review included 1,069 patients with metastatic melanoma or renal cell carcinoma who received high-dose interleukin-2 alone or in combination with other immunotherapy or chemotherapy from July 1985-July 2000. All patients were evaluated for both toxicity and response. Only the first exposure to interleukin-2 was considered. Parameters evaluated among the groups included toxicity profiles, reasons for stopping treatment, number of interleukin-2 doses per cycle, and response to therapy. Three patient groups were compared. Group 1 (n = 27) comprised patients with previously treated brain metastases (surgery or radiation), group 2 (n = 37) comprised patients with untreated brain metastases, and group 3 (n = 1,005) comprised patients without brain metastases. For most comparisons between patients with brain metastases and those without, no significant differences were noted in toxicity profiles or reasons for stopping interleukin-2 therapy. Patients with previously treated brain metastases received fewer interleukin-2 doses per cycle (median, 6.5) than patients with previously untreated brain metastases (median, 7.5) or patients without brain metastases (median, 7.5). Patients with previously treated brain metastases demonstrated an 18.5% overall clinical response to interleukin-2 treatment. However, patients with evaluable (previously untreated) brain metastases had an overall 5.6% response rate, which was less than the 19.8% response rate of patients without brain metastases. Two of thirty-six patients with evaluable brain metastases demonstrated objective regression of intracranial and extracranial disease after receiving interleukin-2. Carefully selected patients with brain metastases can safely receive high-dose interleukin-2, and some can experience a response to treatment at intracranial and extracranial disease sites.

They have been proposed to deliver DNA-reactive agents to specific DNA sequences for gene targeting applications. We suggested the use of super(125)I-labeled TFO for delivery of the energy of radioiodine decay to specific genes. This approach is called antigene radiotherapy. Here we demonstrate the ability of super(125)I-labeled TFO to produce sequence-specific breaks within a target in the human mdr1 gene in cultured cells. TFO and TFO conjugated with a nuclear localization signal peptide (NLS) were delivered into cells using cationic liposomes. This was done either alone or in the presence of an excess of a "ballast" oligonucleotide with an unrelated sequence. In all cases, nuclear localization of TFO and survival of the cells after treatment has been confirmed. Breaks in the gene target were analyzed by restriction enzyme digestion of the DNA recovered from the TFO-treated cells followed by Southern hybridization with DNA probes flanking the target sequence. We have found that TFO/NLS conjugates cleave the target in a concentration-dependent manner regardless of the presence of the "ballast" oligonucleotide. In contrast, TFO without NLS cleaved the target only in the presence of an excess of the "ballast." We hypothesize that TFO and TFO/NLS are delivered into the nucleus by different pathways. These results provide a new insight into the mechanism of intracellular transport of oligonucleotides and open new avenues for improvement of the efficacy of antigene therapies.

People are exposed to arsenic not only through drinking water but also through arsenic-contaminated air and food. Here we report the health effects of arsenic exposure from burning high arsenic-containing coal in Guizhou, China. Coal in this region has undergone mineralization and thus produces high concentrations of arsenic. Coal is burned inside the home in open pits for daily cooking and crop drying, producing a high concentration of arsenic in indoor air. Arsenic in the air coats and permeates food being dried producing high concentrations in food; however, arsenic concentrations in the drinking water are in the normal range. The estimated sources of total arsenic exposure in this area are from arsenic-contaminated food (50-80%), air (10-20%), water (1-5%), and direct contact in coal-mining workers (1%). At least 3,000 patients with arsenic poisoning were found in the Southwest Prefecture of Guizhou, and approximately 200,000 people are at risk for such overexposures. Skin lesions are common, including keratosis of the hands and feet, pigmentation on the trunk, skin ulceration, and skin cancers. Toxicities to internal organs, including lung dysfunction, neuropathy, and nephrotoxicity, are clinically evident. The prevalence of hepatomegaly was 20%, and cirrhosis, ascites, and liver cancer are the most serious outcomes of arsenic poisoning. The Chinese government and international organizations are attempting to improve the house conditions and the coal source, and thereby protect human health in this area.

Following attachment of the cell pellets to the polymer surfaces, chondrogenesis was induced by culturing the constructs for 3 weeks in a serum-free, chemically defined, chondrogenic differentiation medium supplemented with transforming growth factor beta -1 (TGF- beta 1). Histochemical analysis showed that the press-coated pellets formed cell layers composed of morphologically distinct, chondrocyte-like cells, surrounded by a fibrous, sulfated proteoglycanrich extracellular matrix. Immunohistochemical analysis detected collagen type II and cartilage proteoglycan link protein within the extracellular matrix. Expression of the cartilage-specific marker genes collagen types II, IX, X, and XI, and aggrecan was detected by RT-PCR. Scanning electron microscopy revealed organized and spatially distinct zones of cells within the cell-polymer constructs, with the superficial layer resembling compact hyaline cartilage. The fabrication method of press-coating biodegradable polymers with mhMSCs allows the in vitro production of cartilage constructs without harvesting chondrocytes from intact articular cartilage surfaces. These constructs may be applicable as prototypes for the reconstruction of articular cartilage defects in humans.

A promising approach is to bypass normal immune regulatory mechanisms by generating an immune response ex vivo, and then to transfer the fully activated immune cells back into the patient. This treatment strategy requires the in vitro expansion of disease-specific T cells to numbers in the billions. In this issue, Maus et al. describe an "artificial APC" that, for the first time, provides a defined system with the capacity to drive large expansions of T cells ex vivo. This powerful artificial APC could augment current methods of T-cell stimulation; and moreover, it may herald a new generation of effector T cells for adoptive therapy.

To examine responsiveness to these epitopes in the absence of infection, we inoculated mice with recombinant lemA (r-lemA) containing f-MIGWII or r-vemA (a variant of r-lemA containing f-MIVIL in place of f-MIGWII) without adjuvant. To monitor responses, we measured peptide-specific cytoplasmic IFN- gamma production ex vivo by freshly harvested splenocytes at varying times post-inoculation. B6 mice inoculated with r-lemA produced substantial numbers of epitope-specific CD8 cells with peak levels on day 7 when there were 1.1 x 10 super(6) f-MIGWII-specific CD8 cells in the spleen (8.2% of total CD8 splenocytes). The r-vemA-treated animals accumulated 0.25 x 10 super(6) cells (1.8% of total CD8 cells) at this time point. Comparable responses were observed after rechallenge of immunized animals. Other elements in the lemA moiety distinct from the immunogenic peptide were required since mice did not respond to equimolar amounts of synthetic f-MIGWII or f-MIVIL alone. In comparative studies, B6 and C3H/HeJ mice responded to r-vemA much more vigorously than BALB/c animals. When r-lemA- or r-vemA-treated B6 animals were challenged i.v. with LM 7 days later, they suppressed splenic accumulation of bacteria much more effectively than controls. On the other hand, antigen-treated animals were not protected against infection 1 month later. Thus, responsive strains of mice respond vigorously to H2-M3-restricted epitopes, even in the absence of bacterial infection or adjuvant. The resulting effectors acutely enhance antimicrobial resistance but do not confer long-term memory protection.

Besides their function as gene delivery vehicles, lentiviral vector backbones containing the cis-acting sequences necessary to perform a complete replication cycle in the presence of viral proteins provided in trans, have the ability to inhibit HIV-1 replication by several mechanisms that include sequestration of the regulatory proteins Tat and Rev, competition for packaging into virions and possibly by inhibition of reverse transcription in heterodimeric virions. Expression of anti-HIV-1 genes in these vectors would strengthen the potency of this inhibition. To avoid self-inhibition of the vector packaging system, lentiviral vectors have to be modified to become resistant to the anti-HIV-1 genes encoded by them. This review discusses the different genetic intervention strategies for gene therapy of HIV-1 infection focusing in the use of lentiviral vectors as the main agents to mediate inhibition of HIV-1 replication. It also discusses possible strategies to adapt HIV-1 or HIV-2 vectors to express the different classes of anti-HIV-1 genes and approaches to improve in vivo vector mobilization.

Research and commercial cigarettes, menthol and nonmenthol, that delivered a wide range of nicotine were evaluated. Menthol (n = 18) and nonmenthol (n = 18) cigarette smokers participated in a single session during which three cigarettes were smoked 45 min apart, in random order. Federal Trade Commission (ETC) nicotine yields of the three cigarettes were: research, low yield, 0.2 mg, commercial cigarettes (average), 1.2 mg; research, high yield, 2.5 mg. Commercial and high-yield cigarettes increased heart rate (HR) and blood pressure more than low-yield cigarettes; although, no differences in exhaled carbon monoxide (CO) occurred. Participants smoked commercial cigarettes faster and with fewer puffs than either of the research cigarette indicating production differences can affect topography. There was a significant group by cigarette interaction on satisfaction, and relief from cigarette craving. High-yield nonmenthol cigarettes reduced craving and were rated as more satisfying than high-yield menthol cigarettes. No differences between menthol and nonmenthol cigarettes on other subjective measures (strength, psychological reward, negative effects) were observed. Our findings indicate that nicotine delivery, but not mentholation, influences cardiovascular and most subjective measures. These results illustrate the importance of threshold levels of nicotine on subjective responses to cigarette smoking.

The optimal site of injection and the migration pattern of these cells remain to be elucidated. We therefore developed a novel method for labeling mouse bone marrow-derived dendritic cells (BMDC) with the positron emitting radioisotope F-18 using N-succinimidyl-4-[F-18]fluorobenzoate, which covalently binds to the lysine residues of cell surface proteins. When we determined the stability of F-18 labeled BMDC, we found that at 4 h only 44 plus or minus 10% of the initial cell-bound activity was retained at 37 degree C, whereas considerably more (91 plus or minus 3%) was retained at 4 degree C. Labeled cells did not exhibit any significant alteration in cell viability or phenotype as determined by trypan blue exclusion and FACS analysis 24 h after radiolabeling. Furthermore, F-18-labeled BMDC stimulated allogeneic T cells in a mixed leukocyte reaction as potently as did sham-treated BMDC and migrated towards secondary lymphoid tissue chemokine (SLC) in a chemotaxis assay in vitro with the same efficiency as sham-treated BMDC. Migration of F-18-labeled BMDC was studied after footpad injection by (1) ex vivo counting of dissected tissues using a gamma counter and (2) in vivo by imaging mice with PiPET, a 2-mm resolution positron projection imager. After 4 h, the ratio between measured activity in draining vs. contralateral (D/C) lymph nodes (LN) was 166 plus or minus 96 (n=7) in the case of live cell injections, whereas if we injected heat-killed F-18-labeled BMDC or F-18-labeled macrophages the D/C ratios were 17 plus or minus 2 (n=2) and 14 plus or minus 4 (n=2), respectively. Injection of cell-free activity in the form of F-18-labeled 4-fluorobenzoic acid resulted in a D/C ratio of 7 plus or minus 2 (n=3), suggesting that the activity measured in the draining lymph node was associated with migrated F-18-labeled BMDC. When F-18-labeled live cells were injected into the footpad, 0.18 plus or minus 0.04% (n=7) of footpad activity was found in the draining LN within 4 h, whereas none was found in the contralateral LN. Quantitative assessment of cell migration by PET projection imaging of mice confirmed the ex-vivo counting results. These studies indicate that PET imaging offers a new approach for in vivo studies of dendritic cell biodistribution and migration.

The cytotoxic effector YopE functions as a potent GTPase-activating protein (GAP) for Rho family GTP-binding proteins, including RhoA, Rac1, and Cdc42. Down-regulation of these molecular switches results in the loss of cell motility and inhibition of phagocytosis, enabling Y. pestis to thrive on the surface of macrophages. We have determined the crystal structure of the GAP domain of YopE (YopE sub(GAP); residues 90-219) at 2.2-Angstrom resolution. Apart from the fact that it is composed almost entirely of alpha -helices, YopE sub(GAP) shows no obvious structural similarity with eukaryotic RhoGAP domains. Moreover, unlike the catalytically equivalent arginine fingers of the eukaryotic GAPs, which are invariably contained within flexible loops, the critical arginine in YopE sub(GAP) (Arg144) is part of an alpha -helix. The structure of YopE sub(GAP) is strikingly similar to the GAP domains from Pseudomonas aeruginosa (ExoS sub(GAP)) and Salmonella enterica (SptP sub(GAP)), despite the fact that the three amino acid sequences are not highly conserved. A comparison of the YopE sub(GAP) structure with those of the Rac1-ExoS sub(GAP) and Rac1-SptP complexes indicates that few, if any, significant conformational changes occur in YopE sub(GAP) when it interacts with its G protein targets. The structure of YopE sub(GAP) may provide an avenue for the development of novel therapeutic agents to combat plague.

Although keratinocyte stem cells have not yet been completely characterized and purified for gene targeting purposes, lentiviral vectors may be superior to retroviral vectors at gene introduction into these stem cells, which are believed to divide and cycle slowly. Our initial in vitro studies demonstrate that lentiviral vectors are able to efficiently transduce nondividing keratinocytes, unlike retroviral vectors, and do not require the lentiviral accessory genes for keratinocyte transduction. When lentiviral vectors expressing green fluorescent protein (GFP) were directly injected into the dermis of human skin grafted onto immunocompromised mice, transduction of dividing basal and nondividing suprabasal keratinocytes could be demonstrated, which was not the case when control retroviral vectors were used. However, flow cytometry analysis demonstrated low transduction efficiency, and histological analysis at later time points provided no evidence for progenitor cell targeting. In an alternative in vivo method, human keratinocytes were transduced in tissue culture (ex vivo) with either lentiviral or retroviral vectors and grafted as skin equivalents onto immunocompromised mice. GFP expression was analyzed in these human skin grafts after several cycles of epidermal turnover, and both the lentiviral and retroviral vector-transduced grafts had similar percentages of GFP-expressing keratinocytes. This ex vivo grafting study provides a good in vivo assessment of gene introduction into progenitor cells and suggests that lentiviral vectors are not necessarily superior to retroviral vectors at introducing genes into keratinocyte progenitor cells during in vitro culture.

In this vector, the drug resistance gene is expressed in avian cells from the long terminal repeat (LTR) promoter, whereas in bacteria the resistance gene is expressed from a bacterial promoter. The vector contains a bacterial origin of replication (ColE1) to allow circular viral DNA to replicate as a plasmid in bacteria. The vector also contains the lac operator sequence, which binds to the lac repressor protein, providing a simple and rapid way to purify the vector DNA. The RSVP plasmid contains the following sequence starting with the 5" end: LTR, gag, pol, env, drug resistance gene, lac operator, ColE1, LTR. After this plasmid was transfected into DF-1 cells, we were able to rescue the circularized unintegrated viral DNA from RSVP simply by transforming the Hirt DNA into Escherichia coli. Furthermore, we were able to rescue the integrated provirus. DNA from infected cells was digested with an appropriate restriction enzyme (ClaI) and the vector-containing segments were enriched using lac repressor protein and then self-ligated. These enriched fractions were used to transform E. coli. The transformation was successful and we did recover integration sites, but higher-efficiency rescue was obtained with electroporation. The vector is relatively stable upon passage in avian cells. Southern blot analyses of genomic DNAs derived from successive viral passages under nonselective conditions showed that the cassette (drug resistance gene- lac operator-ColE1) insert was present in the vector up to the third viral passage for both resistance genes, which suggests that the RSVP vectors are stable for approximately three viral passages. Together, these results showed that RSVP vectors are useful tools for cloning unintegrated or integrated viral DNAs.

They can be dose-limiting and debilitating or life-threatening. There is now evidence that some late effects may be preventable or partially reversible. A workshop, 'Modifying Normal Tissue Damage Postirradiationa, was sponsored by the Radiation Research Program of the National Cancer Institute to identify the current status of and research needs and opportunities in this area. Mechanistic, genetic and physiological studies of the development of late effects are needed and will provide a rational basis for development of treatments. Interdisciplinary teams will be needed to carry out this research, including pathologists, physiologists, geneticists, molecular biologists, experts in functional imaging, wound healing, burn injury, molecular biology, and medical oncology, in addition to radiation biologists, physicists and oncologists. The participants emphasized the need for developing and choosing appropriate models, and for radiation dose-response studies to determine whether interventions remain effective at the radiation doses used clinically. Both preclinical and clinical studies require long-term follow-up, and easier-to-use, more objective clinical scoring systems must be developed and standardized. New developments in biomedical imaging should provide useful tools in all these endeavors. The ultimate goals are to improve the quality of life and efficacy of treatment for cancer patients treated with radiotherapy.

AN - 71482353; 11840338 AB - We have used serial analysis of gene expression (SAGE) to investigate the influence of the von Hippel-Lindau (VHL) gene on global gene expression profiles. SAGE libraries were prepared from renal cell carcinoma (RCC) lines that either lack (parental) or express wild-type VHL (wtVHL). Comparison of these libraries revealed some differentially expressed genes (Glut-1, for example) that were known to be influenced by VHL, but the majority of genes had not previously been reported to be affected by the cell's VHL status. The identification of several genes involved in TNFalpha-mediated events prompted us to compare the sensitivity of cells with different VHL status in TNFalpha cytotoxicity assays. Strikingly, VHL-deficient cells were much more resistant to the toxic influence of TNFalpha. We propose that VHL-dependent sensitization of RCC cells to TNFalpha-mediated killing may contribute to VHL's growth suppressive function.

AN - 71449448; 11840334 AB - The conditional expression of activated HER2/neu gene under its endogenous promoter in the mammary epithelium of the mouse results in accelerated lobular development and focal mammary tumors. Carcinogenesis, however, requires amplification and considerably increased expression levels of oncogenic neu. Deducing from the multiple genetic aberrations required for human breast cancer to develop, we hypothesized that in addition to the over-expression of an activated HER2/neu, secondary aberrations would occur. We have therefore conducted a genomic screen for chromosomal imbalances and translocations using comparative genomic hybridization and spectral karyotyping. The results reveal a moderate degree of chromosomal instability and micronuclei formation in short-term cultures established from primary tumors. Genomic instability appears to be linked to the amplification of functional centrosomes, a phenomenon that we frequently observed in other tumor types. Seventy per cent of the tumors revealed genomic amplification of HER2/neu, often in the form of double minute chromosomes, which correlated with recurring loss of mouse chromosome 4D-E, a region that is orthologous to distal human chromosome 1p. It is likely that this region contains putative tumor suppressor genes whose inactivation is required for tumor formation in this model of human breast cancer.

AN - 71441926; 11834295 AB - Specific [3H]resiniferatoxin (RTX) binding detects the vanilloid receptor type I (VR1). In the present study we demonstrate specific, high-affinity, saturable [3H]RTX binding in various areas of monkey brain not known to be innervated by primary afferent neurons as well as in spinal cord and dorsal root ganglion neurons of the same origin. Detailed pharmacological characterization and comparison revealed no major difference in binding affinities between the peripheral and the central sites as measured by K(d)/K(i) values. In general, lower receptor density was measured in selected brain areas than in the periphery. Areas with higher receptor density were detected in the locus ceruleus, preoptic area, and medial basal hypothalamus of the brain. Both capsaicin and the competitive antagonist capsazepine inhibited the specific binding of [3H]RTX to membrane preparations of the dorsal horn of the spinal cord and dorsal root ganglia with K(i) values of 4.3+/-0.32 microM and 2.7+/-0.33 microM, respectively. Inhibition was observed in the central areas (hypothalamus) with K(i) values of 0.95+/-0.1 microM for capsaicin and 0.86+/-0.11 microM for capsazepine. Previous biological and pharmacological evidence suggested that vanilloid receptors were present in the brain. Our results demonstrate that the pharmacological properties of both the peripheral and central receptor sites display appropriate pharmacological similarity to represent the same receptor class. The modest differences in ligand affinities for the vanilloid receptor expressed in the brain nuclei and the dorsal root ganglion neurons may correspond to differences in sequence, modification or associated proteins.

AN - 71439112; 11834296 AB - Dehydroepiandrosterone (DHEA) can function to protect neural precursors and their progeny targeted with toxic insults; however, the molecular mechanisms underlying the neuroprotective effects of DHEA are not understood. We cultured neural precursors from the embryonic forebrain of rats and examined the effects of DHEA and its sulfated derivative (DHEAS) on the activation of the serine-threonine protein kinase Akt, which is widely implicated in cell survival signaling. We found that DHEA activated Akt in neural precursor culture, in association with a decrease in apoptosis. In contrast, DHEAS decreased activated Akt levels and increased apoptosis. The effects of DHEA on neural cell survival and activation of Akt were not blocked by the steroid hormone antagonists flutamide and tamoxifen, but both were blocked by a PI3-K inhibitor, LY294002. These findings suggest that during neurogenesis in the developing cortex, DHEA and DHEAS regulate the survival of neural precursors and progeny through the Akt signaling pathway. JF - Brain research.

AN - 71416920; 11804607 AB - In the 1970s, several thermosensitive alleles of dnaE (encoding the alpha-catalytic subunit of pol III) were isolated. Genetic characterization of these dnaE mutants revealed that some are mutator alleles at permissive temperature. We have determined the nucleotide changes of five such temperature sensitive mutator alleles (dnaE9, dnaE74, dnaE486, dnaE511, and dnaE1026) and find that most are single missense mutations. The exception is dnaE1026 which is a compound allele consisting of multiple missense mutations. When the previously characterized mutator alleles were moved into a lexA51(Def) recA730 strain, dnaE486, dnaE1026 and dnaE74 conferred a modest approximately two-six-fold increase in spontaneous mutagenesis when grown at the permissive temperature of 28 degrees C, while dnaE9 and dnaE511 actually resulted in a slight decrease in spontaneous mutagenesis. In isogenic DeltaumuDC derivatives, the level of spontaneous mutagenesis dropped significantly, although in each case, the overall mutator effect conferred by the dnaE allele was relatively larger, with all five dnaE alleles conferring an increased spontaneous mutation rate approximately 5-22-fold over the isogenic dnaE+ DeltaumuDC strain. Interestingly, the temperature sensitivity conferred by each allele varied considerably in the lexA51(Def) recA730 background and in many cases, this phenotype was dependent upon the presence of functional pol V (UmuD'2C). Our data suggest that pol V can compete effectively with the impaired alpha-subunit for a 3' primer terminus and as a result, a large proportion of the phenotypic effects observed with strains carrying missense temperature sensitive mutations in dnaE can, in fact, be attributed to the actions of pol V rather than pol III.

AN - 71440632; 11717310 AB - Nedd4 is a HECT domain-containing ubiquitin ligase that mediates ubiquitylation and proteasome degradation of target proteins. The molecular basis for the interaction of Nedd4 with substrates lies in its WW domains, which can bind proline-rich (PY) domains in target proteins. Nedd4 is a developmentally expressed protein and may have a fundamental role to play in embryonic processes. However, whether Nedd4 has such a function is currently unknown, in part because few developmentally regulated ubiquitylation substrates have been identified or characterized. We have carried out a yeast two-hybrid screen and identified four proteins expressed in the mid-gestation embryo that are able to interact with Nedd4. Characterization of their functional interaction with Nedd4 in vitro and in vivo demonstrated that three of the four are bona fide Nedd4 binding partners, and two have the capacity to be ubiquitylation substrates. One of these is the first identified nonviral substrate for Nedd4-mediated monoubiquitylation. Interestingly, neither of these two ubiquitylated proteins interacts with Nedd4 through PY-mediated mechanisms. For one of the three Nedd4 binding partners, there was no discernable evidence of ubiquitylation. However, this protein clearly associates with Nedd4 through its PY domains and can alter the location of Nedd4 in cells, suggesting a role other than as a ubiquitylation substrate.

Previous experiments suggested that repression involves the interaction of two DNA-bound GalR proteins, which generates a 113-bp DNA loop encompassing the promoter region. Interaction between two DNA-bound proteins would be allowed if the binding sites on DNA are properly aligned. To test the idea that the observed repression of gal transcription in vitro is mediated by DNA looping, we investigated the effect of changing the relative angular orientation of O sub(E) and O sub(I) in the DNA helix. We found that repression is a periodic function of the distance between the two operator sites. Since repression recurred commensurate with DNA helical repeat, we conclude that the observed in vitro repression is mediated by DNA looping and the in vitro conditions reflect the in vivo situation.

AN - 71395508; 11807146 AB - Patients with neutropenia and persistent fever are often treated empirically with amphotericin B or liposomal amphotericin B to prevent invasive fungal infections. Antifungal triazoles offer a potentially safer and effective alternative. In a randomized, international, multicenter trial, we compared voriconazole, a new second-generation triazole, with liposomal amphotericin B for empirical antifungal therapy. A total of 837 patients (415 assigned to voriconazole and 422 to liposomal amphotericin B) were evaluated for success of treatment. The overall success rates were 26.0 percent with voriconazole and 30.6 percent with liposomal amphotericin B (95 percent confidence interval for the difference, -10.6 to 1.6 percentage points); these rates were independent of the administration of antifungal prophylaxis or the use of colony-stimulating factors. There were fewer documented breakthrough fungal infections in patients treated with voriconazole than in those treated with liposomal amphotericin B (8 [1.9 percent] vs. 21 [5.0 percent], P=0.02). The voriconazole group had fewer cases of severe infusion-related reactions (P<0.01) and of nephrotoxicity (P<0.001). The incidence of hepatotoxicity was similar in the two groups. Patients receiving voriconazole had more episodes of transient visual changes than those receiving liposomal amphotericin B (22 percent vs. 1 percent, P<0.001) and more hallucinations (4.3 percent vs. 0.5 percent, P<0.001). Parenteral voriconazole was changed to the oral formulation in 22 percent of the voriconazole group, with a reduction in the mean duration of hospitalization by one day in all patients (P=0.17) but by two days in patients at high risk (P=0.03). Voriconazole is a suitable alternative to amphotericin B preparations for empirical antifungal therapy in patients with neutropenia and persistent fever.

AN - 71494295; 11867210 AB - Cockayne syndrome (CS) is a human genetic disorder characterized by several neurological and developmental abnormalities. Two genetic complementation groups, CS-A and CS-B, have been identified. The CSB protein belongs to helicase superfamily 2, and to the SWI/SNF family of proteins. The CSB protein is implicated in transcription-coupled repair (TCR), basal transcription and chromatin remodeling. In addition, CS cells undergo UV-induced apoptosis at much lower doses than normal cells. However, the molecular function of the CSB protein in these biological pathways has remained unclear. Evidence indicates that the integrity of the Walker A and B boxes (motifs I and II) are important for CSB function, but the functional significance of the helicase motifs Ia, III--IV has not been previously examined. In this study, single amino acid changes in highly conserved residues of helicase motifs Ia, III, V, VI and a second putative nucleotide-binding motif (NTB) of the CSB protein were generated by site-directed mutagenesis to analyze the genetic function of the CSB protein in survival, RNA synthesis recovery and apoptosis after UV treatment. The survival analysis of these CS-B mutant cell lines was also performed after treatment with the chemical carcinogen, 4-nitroquinoline-1-oxide (4-NQO). The lesions induced by UV light, cyclobutane pyrimidine dimers, are known to be repaired by TCR whereas the lesions induced by 4-NQO are repaired by global genome repair. The results of this study demonstrate that the point mutations in highly conserved residues of helicase motifs Ia, III, V and VI abolished the genetic function of the CSB protein in survival, RNA synthesis recovery and apoptosis after UV treatment. Similarly, the same mutants failed to complement the sensitivity toward 4-NQO. Thus, the integrity of these helicase motifs is important for the biological function of the CSB protein. On the contrary, a point mutation in a C-terminal, second, NTB motif of the CSB protein showed full complementation in the ability to repair damage induced by UV light or 4-NQO, suggesting that this motif is not important for the CSB repair function.

AN - 71407410; 11790113 AB - The bacterial PEP:sugar phosphotransferase system couples the phosphorylation and translocation of specific sugars across the membrane. The activity of the first protein in this pathway, enzyme I (EI), is regulated by a monomer-dimer equilibrium where a Mg(2+)-dependent autophosphorylation by PEP requires the dimer. Dimerization constants for dephospho- and phospho-EI and inactive mutants EI(H189E) and EI(H189A) (in which Glu or Ala is substituted for the active site His189) have been measured under a variety of conditions by sedimentation equilibrium at pH 7.5 and 4 and 20 degrees C. Concurrently, thermal unfolding of these forms of EI has been monitored by differential scanning calorimetry and by changes in the intrinsic tryptophanyl residue fluorescence. Phosphorylated EI and EI(H189E) have 10-fold increased dimerization constants [ approximately 2 x 10(6) (M monomer)(-1)] compared to those of dephospho-EI and EI(H189A) at 20 degrees C. Dimerization is strongly promoted by 1 mM PEP with 2 mM MgCl(2) [K(A)' > or = 10(8) M(-1) at 4 or 20 degrees C], as demonstrated with EI(H189A) which cannot undergo autophosphorylation. Together, 1 mM PEP and 2 mM Mg(2+) also markedly stabilize and couple the unfolding of C- and N-terminal domains of EI(H189A), increasing the transition temperature (T(m)) for unfolding the C-terminal domain by approximately 18 degrees C and that for the N-terminal domain by approximately 9 degrees C to T(max) congruent with 63 degrees C, giving a value of K(D)' congruent with 3 microM PEP at 45 degrees C. PEP alone also promotes the dimerization of EI(H189A) but only increases T(m) approximately 5 degrees C for C-terminal domain unfolding without affecting N-terminal domain unfolding, giving an estimated value of K(D)' congruent with 0.2 mM for PEP dissociation in the absence of Mg(2+) at 45 degrees C. In contrast, the dimerization constant of phospho-EI at 20 degrees C is the same in the absence and presence of 5 mM PEP and 2 mM MgCl(2). Thus, the separation of substrate binding effects from those of phosphorylation by studies with the inactive EI(H189A) has shown that intracellular concentrations of PEP and Mg(2+) are important determinants of both the conformational stability and dimerization of dephospho-EI.

These MOSC domains contain an absolutely conserved cysteine and occur either as stand-alone forms such as the bacterial YiiM proteins, or fused to other domains such as a NifS-like catalytic domain in Molybdenum cofactor sulfurase. The MOSC domain is predicted to be a sulfur-carrier domain that receives sulfur abstracted by the pyridoxal phosphate-dependent NifS-like enzymes, on its conserved cysteine, and delivers it for the formation of diverse sulfur-metal clusters. The identification of this domain may clarify the mechanism of biogenesis of various metallo-enzymes including Molybdenum cofactor-containing enzymes that are compromised in human type II xanthinuria.

(1997). Here, we report the highly efficient transduction into different human, murine and monkey cell lines using a scaled-up protocol for producing SV40 pseudovirions, packaged in vitro, carrying the human multidrug-resistance gene MDR1 encoding P-glycoprotein (P-gp) or the green fluorescent protein reporter gene (GFP) under control of SV40 and cytomegalovirus (CMV) promoters. The percentage of expressing cells was proportional to the number of transducing particles, with close to 100% of cells transduced at optimal ratios of transducing particles to cells. The ability to confer multidrug resistance was evaluated by measuring dye efflux and cell-surface expression in infected cells. The relative level of expression of P-gp driven by the different promoters varied among different cell lines. In human lymphoblastoid cells, which express high levels of major histocompatibility complex (MHC) class I (a surface receptor for SV40), constructs that carry an intron yield the highest expression. Our experiments further demonstrate that MDR1 and GFP expression driven by these promoters is transient; however, transduced cells remain MDR1-positive if selected in colchicine. Thus, the SV40 vectors are well suited to situations in which only short-term expression is required or expression is selected, such as for bone marrow protection during chemotherapy.

IL-10 is a potent antiinflammatory/immune cytokine, which has received growing attention for its therapeutic potential. Human IL-10 (hIL-10) production was virus dose dependent after in vitro infection of HSG cells, a human submandibular gland cell line. The vector-derived hIL-10 produced was biologically active, as the medium from rAAVhIL10-infected HSG cells caused a dose-dependent blockade of IL-12 secretion from spleen cells of IL-10 knockout mice challenged with heat-killed Brucella abortus. Administration of rAAVhIL10 (10 super(10) genomes per gland) to both mouse submandibular glands led to hIL-10 secretion into the bloodstream ( similar to 1-5 pg/ml), that is, in an endocrine manner, which was stable for similar to 2 months. Salivary gland administration of rAAVhIL10 under experimental conditions was more efficacious than intravenous administration ( similar to 0.5-0.7 pg/ml). Also, hIL-10 was readily secreted in vitro from organ cultures of minced submandibular glands infected with rAAVhIL10, 6 or 8 weeks earlier. Consistent with these results, hIL-10 mRNA was detected by reverse transcription-polymerase chain reaction in submandibular glands of mice infected with rAAVhIL10 but not from control mice. At these doses, little to no hIL-10 was detected in mouse saliva. Using a rAAV serotype 2 vector encoding beta -galactosidase, we observed that the primary parenchymal target cells were ductal. These findings represent the first report of rAAV use to target exocrine glands for systemic secretion of a therapeutic protein, and support the notion that rAAV serotype 2 vectors may be useful in salivary glands for local (periglandular) and systemic gene-based protein therapeutics.

AN - 71369399; 11698401 AB - The structural changes involved in ligand-dependent activation of G protein-coupled receptors are not well understood at present. To address this issue, we developed an in situ disulfide cross-linking strategy using the rat M(3) muscarinic receptor, a prototypical G(q)-coupled receptor, as a model system. It is known that a tyrosine residue (Tyr(254)) located at the C terminus of transmembrane domain (TM) V and several primarily hydrophobic amino acids present within the cytoplasmic portion of TM VI play key roles in determining the G protein coupling selectivity of the M(3) receptor subtype. To examine whether M3 receptor activation involves changes in the relative orientations of these functionally critical residues, pairs of cysteine residues were substituted into a modified version of the M(3) receptor that contained a factor Xa cleavage site within the third intracellular loop and lacked most endogenous cysteine residues. All analyzed mutant receptors contained a Y254C point mutation and a second cysteine substitution within the segment Lys(484)-Ser(493) at the intracellular end of TM VI. Following their transient expression in COS-7 cells, mutant receptors present in their native membrane environment (in situ) were subjected to mild oxidizing conditions, either in the absence or in the presence of the muscarinic agonist, carbachol. The successful formation of disulfide cross-links was monitored by studying changes in the electrophoretic mobility of oxidized, factor Xa-treated receptors on SDS gels. The observed cross-linking patterns indicated that M(3) receptor activation leads to structural changes that allow the cytoplasmic ends of TM V and TM VI to move closer to each other and that also appear to involve a major change in secondary structure at the cytoplasmic end of TM VI. This is the first study employing an in situ disulfide cross-linking strategy to examine agonist-dependent dynamic structural changes in a G protein-coupled receptor.

AN - 71446782; 11850076 AB - Oncogene alterations have been clearly demonstrated to be related to the carcinogenesis and progression of oral squamous cell carcinoma (OSCC). However, the analysis of these alterations for screening and early diagnostic purposes generally requires invasive techniques for surgical removal of pathological epithelium. The aim of the present study was to assess the feasibility of fluorescence in situ hybridization (FISH) analysis of HER-2/neu amplification in oral mucosa brushings and to compare the HER-2/neu status with the history and smoking and drinking habits of healthy subjects. Cells obtained by centrifugation of oral brushings from 21 subjects (overall no. of cells: 5125) were suspended in physiological saline and fixed onto two slides for cytological evaluation and FISH analysis (dual-target, dual-color fluorescence assay) of the HER-2/neu gene and CEP17 centromere. A mean of 89.8% of the cells showed two HER-2/neu signals and a mean of 94% had two CEP17 signals at fluorescent microscopy. Finally, a mean of 96% of cells with HER-2/neu / CEP17 had a ratio equal to 1. No association between smoking and drinking habits, age and the HER-2/neu and CEP17 characteristics evaluated by FISH was found.

AN - 71414440; 11795873 AB - L-glutamate dehydrogenase (GDH) is stable in exponentially growing Escherichia coli cells but is degraded at a rate of 20-30% per hour in cells starved for either nitrogen or carbon. GDH degradation is energy-dependent, and mutations in ATP-dependent proteases, ClpAP or Lon lead to partial stabilization. Degradation is inhibited by chloramphenicol and is completely blocked in relA mutant cells, suggesting that ribosome-mediated signaling may facilitate GDH degradation. Purified GDH has a single tight site for NADPH binding. Binding of NADPH in the absence of other ligands leads to destabilization of the enzyme. NADPH-induced instability and sensitivity to proteolysis is reversed by tri- and dicarboxylic acids or nucleoside di- and triphosphates. GTP and ppGpp bind to GDH at an allosteric site and reverse the destabilizing effects of NADPH. Native GDH is resistant to degradation by several purified ATP-dependent proteases: ClpAP, ClpXP, Lon, and ClpYQ, but denatured GDH is degraded by ClpAP. Our results suggest that, in vivo, GDH is sensitized to proteases by loss of a stabilizing ligand or interaction with an destabilizing metabolite that accumulates in starving cells, and that any of several ATP-dependent proteases degrade the sensitized protein.

AN - 71403352; 11795874 AB - Phorbol 12-myristate-13-acetate (PMA), a potent tumor promoter and activator of most protein kinase C (PKC) isotypes, was found to significantly inhibit the growth of low population density (1-5% confluency) NIH 3T3 cells. Higher cell population density (above 10% confluency) provided protection from this growth inhibitory effect of PMA. PMA-induced growth arrest is accompanied by an elevation in the level of p21(Cip1) protein, along with cell cycle arrest at the G1/S transition. Activation of PKC is required for this growth inhibitory response since the pan PKC inhibitor GF109203 blocked this effect of PMA. However, the classical PKC inhibitor Gö6976 had no effect, strongly suggesting the involvement of novel PKC isotypes (delta and/or epsilon). Overexpression of PKCepsilon, but not PKCdelta, was found to potentiate PMA-induced growth inhibition. Overexpression of a kinase-inactive dominant-negative mutant of PKCepsilon (K437R) decreased the growth inhibitory effect of PMA and also blocked the PMA-induced increase in the level of p21(Cip1) protein. Taken together, these results indicate that PMA has a cell population density-dependent effect on the growth of NIH 3T3 cells and that the PMA growth inhibitory effect at low cell population density is mediated through activation of PKCepsilon.

AN - 71392386; 11809726 AB - RNA interference (RNAi) is a mechanism that appears to control unwanted gene expression in a wide range of species. In Drosophila, RNAi is most effectively induced by double-stranded RNAs (dsRNAs) of over approximately 80 nucleotides (nt) and in mammalian cells an RNAi-like inhibition of gene expression has been shown to be mediated by dsRNAs of approximately 21-23 nt. To test if RNAi can be used to specifically down-regulate a human disease-related transcript we have used Drosophila and human tissue culture models of the dominant genetic disorder spinobulbar muscular atrophy (SBMA). A variety of different dsRNAs were assessed for the ability to inhibit expression of transcripts that included a truncated human androgen receptor (ar) gene containing different CAG repeat lengths (16-112 repeats). In Drosophila cells, dsRNAs corresponding to non-repetitive sequences mediated a high degree of sequence-specific inhibition, whereas RNA duplexes containing CAG repeat tracts only induced gene-specific inhibition when flanking ar sequences were included; dsRNAs containing various lengths of CAG repeats plus ar sequences were unable to induce allele-specific interference. In mammalian cells we tested sequence-specific small dsRNAs of 22 nt; these rescued the toxicity and caspase-3 activation induced by plasmids expressing a transcript encoding an expanded polyglutamine tract. This study demonstrates the feasibility of targeting a transcript associated with an important group of genetic diseases by RNAi.

AN - 71364587; 11788711 AB - During a systematic analysis of conserved gene context in prokaryotic genomes, a previously undetected, complex, partially conserved neighborhood consisting of more than 20 genes was discovered in most Archaea (with the exception of Thermoplasma acidophilum and Halobacterium NRC-1) and some bacteria, including the hyperthermophiles Thermotoga maritima and Aquifex aeolicus. The gene composition and gene order in this neighborhood vary greatly between species, but all versions have a stable, conserved core that consists of five genes. One of the core genes encodes a predicted DNA helicase, often fused to a predicted HD-superfamily hydrolase, and another encodes a RecB family exonuclease; three core genes remain uncharacterized, but one of these might encode a nuclease of a new family. Two more genes that belong to this neighborhood and are present in most of the genomes in which the neighborhood was detected encode, respectively, a predicted HD-superfamily hydrolase (possibly a nuclease) of a distinct family and a predicted, novel DNA polymerase. Another characteristic feature of this neighborhood is the expansion of a superfamily of paralogous, uncharacterized proteins, which are encoded by at least 20-30% of the genes in the neighborhood. The functional features of the proteins encoded in this neighborhood suggest that they comprise a previously undetected DNA repair system, which, to our knowledge, is the first repair system largely specific for thermophiles to be identified. This hypothetical repair system might be functionally analogous to the bacterial-eukaryotic system of translesion, mutagenic repair whose central components are DNA polymerases of the UmuC-DinB-Rad30-Rev1 superfamily, which typically are missing in thermophiles.

AN - 71361863; 11781257 AB - To assess the safety and efficacy of nonmyeloablative allogeneic transplantation in patients with HIV infection, a clinical protocol was initiated in patients with refractory hematologic malignancies and concomitant HIV infection. The results from the first 2 patients are reported. The indications for transplantation were treatment-related acute myelogenous leukemia and primary refractory Hodgkin disease in patients 1 and 2, respectively. Only patient 1 received genetically modified cells. Both patients tolerated the procedure well with minimal toxicity, and complete remissions were achieved in both patients, but patient 2 died of relapsed Hodgkin disease 12 months after transplantation. Patient 1 continues in complete remission with undetectable HIV levels and rising CD4 counts, and with both the therapeutic and control gene transfer vectors remaining detectable at low levels more than 2 years after transplantation. These results suggest that nonmyeloablative allogeneic transplantation in the context of highly active antiretroviral therapy is feasible in patients with treatment-sensitive HIV infection.

AN - 71356530; 11784785 AB - Urocortin and urocortin II are members of the corticotropin-releasing hormone (CRH) family of neuropeptides that function to regulate stress responses. Two high-affinity G-protein-coupled receptors have been identified that bind CRH and/or urocortin I and II, designated CRHR1 and CRHR2, both of which are present in hippocampal regions of mammalian brain. The hippocampus plays an important role in regulating stress responses and is a brain region in which neurons are vulnerable during disease and stress conditions, including cerebral ischemia, Alzheimer's disease, and anxiety disorders. Here we report that urocortin exerts a potent protective action in cultured rat hippocampal neurons with concentrations in the range of 0.5-5.0 pm, increasing the resistance of the cells to oxidative (amyloid beta-peptide, 4-hydroxynonenal, ferrous sulfate) and excitotoxic (glutamate) insults. We observed that urocortin is 10-fold more potent than CRH in protecting hippocampal neurons from insult, whereas urocortin II is ineffective. RT-PCR and sequencing analyses revealed the presence of both CRHR1 and CRHR2 in the hippocampal cultures, with CRHR1 being expressed at much higher levels than CRHR2. Using subtype-selective CRH receptor antagonists, we provide evidence that the neuroprotective effect of exogenously added urocortin is mediated by CRHR1. Furthermore, we provide evidence that the signaling pathway that mediates the neuroprotective effect of urocortin involves cAMP-dependent protein kinase, protein kinase C, and mitogen-activated protein kinase. This is the first demonstration of a biological activity of urocortin in hippocampal neurons, suggesting a role for the peptide in adaptive responses of hippocampal neurons to potentially lethal oxidative and excitotoxic insults.

AN - 71355268; 11777988 AB - In the present study, we define the relation between TGF-beta and IL-10 in the regulation of the Th1-mediated inflammation occurring in trinitrobenzene sulfonic acid (TNBS)-colitis. In initial studies, we showed that the feeding of trinitrophenol-haptenated colonic protein to SJL/J mice induces CD4(+) regulatory T cells that transfer protection from induction of TNBS-colitis, and that such protection correlates with cells producing TGF-beta, not IL-10. Further studies in which SJL/J mice were fed haptenated colonic protein, and then administered either anti-TGF-beta or anti-IL-10 at the time of subsequent TNBS administration per rectum, showed that while both Abs abolished protection, anti-TGF-beta administration prevented TGF-beta secretion, but left IL-10 secretion intact; whereas anti-IL-10 administration prevented both TGF-beta secretion and IL-10 secretion. Thus, it appeared that the protective effect of IL-10 was an indirect consequence of its effect on TGF-beta secretion. To establish this point further, we conducted adoptive transfer studies and showed that anti-IL-10 administration had no effect on induction of TGF-beta producing T cells in donor mice. However, it did inhibit their subsequent expansion in recipient mice, probably by regulating the magnitude of the Th1 T cell response which would otherwise inhibit the TGF-beta response. Therefore, these studies suggest that TGF-beta production is a primary mechanism of counter-regulation of Th1 T cell-mediated mucosal inflammation, and that IL-10 is necessary as a secondary factor that facilitates TGF-beta production.

AN - 71347156; 11740713 AB - Herbal therapies are widely used, but there are few data on their interactions with conventional medications. This study evaluated the effect of garlic supplements on the pharmacokinetics of saquinavir. Ten healthy volunteers received 10 doses of saquinavir (Fortovase) at a dosage of 1200 mg 3 times daily with meals for 4 days on study days 1-4, 22-25, and 36-39, and they received a total of 41 doses of garlic caplets taken 2 times daily on study days 5-25. Blood samples were obtained on study days 4, 25, and 39 for determination of saquinavir plasma pharmacokinetic parameters. In the presence of garlic, the mean saquinavir area under the curve (AUC) during the 8-h dosing interval decreased by 51%, trough levels at 8 h after dosing decreased by 49%, and the mean maximum concentrations (Cmax) decreased by 54%. After the 10-day washout period, the AUC, trough, and Cmax values returned to 60%-70% of their values at baseline. Patients should use caution when combining garlic supplements with saquinavir when it is used as a sole protease inhibitor.

Enantioselective separations were achieved on a beta -cyclodextrin chiral stationary phase (CYCLOBOND I 2000) with a mobile phase consisting of diethylamine acetate (0.25%, pH 4.4):methanol:acetonitrile {85:7.5:7.5, (v/v/v)} and a flow-rate of 0.5 ml/min. For CP, the enantioselectivity ( alpha ) of the separation was 1.12 with a resolution factor (R sub(s)) of 1.17. The method was validated for CP by using mass spectroscopy detection (MSD). Concentrations of each enantiomer could be measured down to 125 pg/ml from a 1-ml plasma sample. Extracted calibration curves were linear from 0.13 to 50.00 ng/ml for each enantiomer. The method was applied to samples from two clinical studies.

Active extrusion via the ArsAB pump is a mechanism for arsenic detoxication in bacteria. However, how arsenic is effluxed from mammalian cells is not completely known. Our recent work shows that acquired arsenic resistance is associated with overexpression of P-glycoprotein and can be reversed by PSC833, an inhibitor for P-glycoprotein. This study utilized the mdr 1a/1b(- / -) mice, which lack mdr 1-type P-glycoproteins, to examine whether these mice are sensitive to arsenic toxicity and have higher arsenic accumulation in their tissues. The mdr 1a/1b(- / -) and wild-type FVB mice were given arsenic as sodium arsenite (12-19 mg/kg, sc) and toxicity was examined 24 h later. The mdr 1a/1b(- / -) mice were more sensitive than wild-type mice to arsenite-induced lethality, with LD sub(50) of 14.5 and 17 mg/kg, respectively. Histologically, arsenite produced more frequent and more severe lesions in the liver and kidney of the mdr 1a/1b(- / -) mice than in wild-type mice. Serum alanine aminotransferase activity and blood urea nitrogen levels, indicative of hepatic and renal damage respectively, were increased 4 to 6-fold in the mdr 1a/1b(- / -) mice as compared with 1-2-fold increases in wild-type mice. The mdr 1a/1b(- / -) mice accumulated more arsenic in the liver (15.3 vs. 5.2 mu g/g), kidney (7.23 vs. 3.22 mu g/g), small intestine (3.98 vs. 1.57 mu g/g) and brain (0.45 vs. 0.17 mu g/g), as compared with wild-type mice 24 h after sodium arsenite (14 mg/kg, s.c.) administration. In summary, this study demonstrated that the mdr 1a/1b(- / -) mice were more sensitive to acute arsenic toxicity and accumulated more arsenic than wild-type mice, suggesting that P-glycoproteins are involved, at least in part, in arsenic efflux in mammalians.

AN - 71359767; 11774337 AB - Protein kinase C (PKC) desensitizes the light response in photoreceptors from the ventral optic nerve of the horseshoe crab Limulus. Photoisomerization of Limulus rhodopsin leads to phosphoinositide hydrolysis, resulting in the production of inositol trisphosphate and diacylglycerol (DAG). Inositol trisphosphate mobilizes intracellular stores of Ca(2+), resulting in photoreceptor excitation in Limulus, while DAG may activate PKC. We investigated whether PKC-mediated desensitization of the photoresponse is accompanied by ultrastructural changes in the rhodopsin-bearing photosensitive membrane (rhabdom) in Limulus ventral photoreceptors. PKC activation by (-)-indolactam V in darkness induces disorganization and swelling of the rhodopsin-containing microvilli and endocytosis of rhabdomeral membrane. The effects of (-)-indolactam V on dark-adapted photoreceptor ultrastructure are reversible, are stereospecific, are blocked by coapplication of PKC inhibitors, and closely match those induced by continuous, bright light. Rhabdom disorganization and endocytosis via PKC activation may, therefore, contribute to desensitization of the light-adapted photoreceptor. Copyright 2001 Wiley-Liss, Inc.

AN - 71360346; 11694527 AB - The highly conserved topological structure of G protein-activated adenylyl cyclases seems unnecessary because the soluble cytoplasmic domains retain regulatory and catalytic properties. Yet, we previously isolated a constitutively active mutant of the Dictyostelium discoideum adenylyl cyclase harboring a single point mutation in the region linking the cytoplasmic and membrane domains (Leu-394). We show here that multiple amino acid substitutions at Leu-394 also display constitutive activity. The constitutive activity of these mutants is not dependent on G proteins or cytosolic regulators, although some of the mutants can be activated to higher levels than wild type. Combining a constitutive mutation such as L394T with K482N, a point mutation that renders the enzyme insensitive to regulators, restores an enzyme with wild type properties of low basal activity and the capacity to be activated by G proteins. Thus regions located outside the cytoplasmic loops of adenylyl cyclases are not only important in the acquisition of an activated conformation, they also have impact on other regions within the catalytic core of the enzyme.

Crucial contacts include both H-2Dd AND beta 2-microglobulin. AN - 71355822; 11696552 AB - Ly49A, an inhibitory C-type lectin-like mouse natural killer cell receptor, functions through interaction with the major histocompatibility complex class I molecule, H-2D(d). The x-ray crystal structure of the Ly49A.H-2D(d) complex revealed that homodimeric Ly49A interacts at two distinct sites of H-2D(d): Site 1, spanning one side of the alpha1 and alpha2 helices, and Site 2, involving the alpha1, alpha2, alpha3, and beta(2)m domains. Mutants of Ly49A, H-2D(d), and beta(2)-microglobulin at intermolecular contacts and the Ly49A dimer interface were examined for binding affinity and kinetics. Although mutations at Site 1 had little affect, several at Site 2 and at the dimer interface hampered the Ly49A.H-2D(d) interaction, with no effect on gross structure or T cell receptor interaction.

Recently, a different form of the reductase (referred to as MsrB) has been detected in several organisms. We show here that MsrB is a selenoprotein that exhibits high specificity for reduction of the R forms of free and protein-bound methionine sulfoxide. The enzyme was partially purified from mouse liver and a derivative of the mouse MsrB gene, in which the codon specifying selenocystein incorporation was replaced by the cystein codon, was prepared, cloned, and overexpressed in Escherichia coli. The properties of the modified MsrB protein were compared directly with those of MsrA. Also, we have shown that in Staphylococcus aureus there are two MsrA and one nonselenoprotein MsrB, which demonstrates the same substrate stereospecificity as the mouse MsrB.

The crystal structure of UvrB revealed a similar fold as found in monomeric DNA helicases. Homology modeling suggested that the beta -hairpin motif of UvrB might be involved in DNA binding (Theis, K., Chen, P. J., Skorvaga, M., Van Houten, B., and Kisker, C. (1999) EMBO J. 18, 6899-6907). To determine a role of the beta -hairpin of Bacillus caldotenax UvrB, we have constructed a deletion mutant, Delta beta h UvrB, which lacks residues Gln-97-Asp-112 of the beta -hairpin. Delta beta h UvrB does not form a stable UvrB-DNA pre-incision complex and is inactive in UvrABC-mediated incision. However, Delta beta h UvrB is able to bind to UvrA and form a complex with UvrA and damaged DNA, competing with wild type UvrB. In addition, Delta beta h UvrB shows wild type-like ATPase activity in complex with UvrA that is stimulated by damaged DNA. In contrast to wild type UvrB, the ATPase activity of mutant UvrB does not lead to a destabilization of the damaged duplex. These results indicate that the conserved beta -hairpin motif is a major factor in DNA binding.

AN - 71415689; 11803464 AB - Small GTPases of the Rho family play a central role in cellular processes that involve the reorganization of the actin-based cytoskeleton. Rho-related GTPases, which include Rac and Cdc42, can also regulate gene expression often through the activation of kinase cascades leading to enhanced activity of stress activated protein kinases (SAPKs), including JNK and p38 MAP kinases. As SAPKs are implicated in programmed cell death, these observations suggest that Rho GTPases may promote the initiation of the apoptotic process. However, recent reports suggest that Rho GTPases can have either a protective or a pro-apoptotic role, depending on the particular cellular context. In an effort to explore the molecular mechanisms underlying these divergent biological activities, we asked whether there was indeed a correlation between the ability to induce SAPKs and apoptosis by Rho family members. We found that although constitutively activated (Q61L) mutants of Rac1, Cdc42, and RhoG, a Rac1 related GTPase of unknown function, potently induce JNK in COS 7 cells, none of these GTPases could induce apoptosis, nor enhance uv-induced cell death. In contrast, Rac1 and RhoG efficiently protected cells from uv-induced apoptosis. Furthermore, we provide evidence that Rac1 and RhoG can activate both apoptotic and anti-apoptotic pathways. Whereas the former is mediated through JNK, the latter is independent on the transcriptional activation of NF-kappaB, a pro-survival pathway, but results from the direct interaction of these GTPases with phosphatidylinositol 3-kinase (PI3K) and the stimulation of Akt. Together, these findings indicate that members of the Rho family of small GTP-binding proteins can provoke the concomitant stimulation of two counteracting signaling pathways, and that their balance ultimately determines the ability of these GTPases to promote cell survival or death.

AN - 71361888; 11756692 AB - Cells in the kidney medulla are subject to variable and often extreme osmotic stress during concentration of the urine. Previous studies showed that renal inner medullary epithelial (IME) cells respond to hypertonicity by G(2) arrest. The purpose of the present study was to investigate the mechanisms involved in initiation and maintenance of G(2) arrest. Rapid initiation of G(2) arrest after UV radiation is mediated by p38 kinase. Here we find that p38 kinase is responsible for rapid initiation of the G(2) delay in IME cells after the hypertonic stress created by adding NaCl. High NaCl, but not high urea, rapidly initiates G(2) arrest. Inhibition of p38 kinase by SB202190 (10 microM) blocks the rapid initiation of this checkpoint both in an immortalized cell line (mIMCD3) and in second-passage IME cells from mouse renal inner medulla. p38 inhibition does not affect exit from G(2) arrest. The rapid initiation of G(2) arrest is followed by inhibition of cdc2 kinase, which is also prevented by SB202190. To assess the possible protective role of G(2) arrest, we measured DNA strand breaks as reflected by immunostaining against phospho-histone H2AX, which becomes phosphorylated on Ser-139 associated with DNA breaks. Abrogation of rapid G(2)/M checkpoint activation by SB202190 increases the histone H2AX phosphorylation in G(2)/M cells. We propose that the rapid initiation of G(2) delay by p38 kinase after hypertonicity protects the cells by decreasing the level of DNA breaks caused by aberrant mitosis entry.

Paper No. 58 N1 - Last updated - 2010-05-03 ER - TY - JOUR T1 - A recombinant vaccine expressed in the milk of transgenic mice protects Aotus monkeys from a lethal challenge with Plasmodium falciparum AN - 18359263; 5293574 AB - Two strains of transgenic mice have been generated that secrete into their milk a malaria vaccine candidate, the 42-kDa C-terminal portion of Plasmodium falciparum merozoite surface protein 1 (MSP1 sub(42)). One strain secretes an MSP1 sub(42) with an amino acid sequence homologous to that of the FVO parasite line, the other an MSP1 sub(42) where two putative N-linked glycosylation sites in the FVO sequence have been removed. Both forms of MSP1 sub(42) were purified from whole milk to greater than 91% homogeneity at high yields. Both proteins are recognized by a panel of monoclonal antibodies and have identical N termini, but are clearly distinguishable by some biochemical properties. These two antigens were each emulsified with Freund's adjuvant and used to vaccinate Aotus nancymai monkeys, before challenge with the homologous P. falciparum FVO parasite line. Vaccination with a positive control molecule, a glycosylated form of MSP1 sub(42) produced in the baculovirus expression system, successfully protected five of six monkeys. By contrast, vaccination with the glycosylated version of milk-derived MSP1 sub(42) conferred no protection compared with an adjuvant control. Vaccination with the nonglycosylated, milk-derived MSP1 sub(42) successfully protected the monkeys, with 4/5 animals able to control an otherwise lethal infection with P. falciparum compared with 1/7 control animals. Analysis of the different vaccines used suggested that the differing nature of the glycosylation patterns may have played a critical role in determining efficacy. This study demonstrates the potential for producing efficacious malarial vaccines in transgenic animals.

The epsilon subunit of the HE complex provides the 3'-exonucleolytic proofreading activity for this enzyme complex. epsilon consists of two domains: an N-terminal domain containing the proofreading exonuclease activity (residues 1-186) and a C-terminal domain required for binding to the polymerase ( alpha ) subunit (residues 187-243). Multidimensional NMR studies of super(2)H-, super(13)C-, and super(15)N-labeled N-terminal domains ( epsilon 186) were performed to assign the backbone resonances and measure H super(N)-H super(N) nuclear Overhauser effects (NOEs). NMR studies were also performed on triple-labeled [U- super(2)H, super(13)C, super(15)N] epsilon 186 containing Val, Leu, and Ile residues with protonated methyl groups, which allowed for the assignment of H super(N)-CH sub(3) and CH sub(3)-CH sub(3) NOEs. Analysis of the super(13)C super( alpha ), super(13)C super( beta ), and super(13)CO shifts, using chemical shift indexing and the TALOS program, allowed for the identification of regions of the secondary structure. H super(N)-H super(N) NOEs provided information on the assembly of the extended strands into a beta -sheet structure and confirmed the assignment of the alpha helices. Measurement of H super(N)-CH sub(3) and CH sub(3)-CH sub(3) NOEs confirmed the beta -sheet structure and assisted in the positioning of the alpha helices. The resulting preliminary characterization of the three-dimensional structure of the protein indicated that significant structural homology exists with the active site of the Klenow proofreading exonuclease domain, despite the extremely limited sequence homology. On the basis of this analogy, molecular modeling studies of epsilon 186 were performed using as templates the crystal structures of the exonuclease domains of the Klenow fragment and the T4 DNA polymerase and the recently determined structure of the E. coli Exonuclease I. A multiple sequence alignment was constructed, with the initial alignment taken from the previously published hidden Markov model and NMR constraints. Because several of the published structures included complexed ssDNA, we were also able to incorporate an A-C-G trinucleotide into the epsilon 186 structure. Nearly all of the residues which have been identified as mutators are located in the portion of the molecule which binds the DNA, with most of these playing either a catalytic or structural role.

Evidence for convergent evolution of promoter sequences. AN - 71350227; 11682475 AB - Omega-crystallin of the scallop lens is an inactive aldehyde dehydrogenase (1A9). Here we have cloned the scallop Omega-crystallin gene. Except for an extra novel first exon, its 14-exon structure agrees well with that of mammalian aldehyde dehydrogenases 1, 2, and 6. The -2120/+63, -714/+63, and -156/+63 Omega-crystallin promoter fragments drive the luciferase reporter gene in transfected alphaTN4-1 lens cells and L929 fibroblasts but not in Cos7 cells. Putative binding sequences for cAMP-responsive element-binding protein (CREB)/Jun, alphaACRYBP1, AP-1, and PAX-6 in the Omega-crystallin promoter are surprisingly similar to the cis-elements used for lens promoter activity of the mouse and chicken alphaA-crystallin genes, which encode proteins homologous to small heat shock proteins. Site-specific mutations in the overlapping CREB/Jun and Pax-6 sites abolished activity of the Omega-crystallin promoter in transfected cells. Gel shift experiments utilizing extracts from the alphaTN4-1, L929, and Cos7 cells and the scallop stomach and oligonucleotides derived from the putative binding sites of the Omega-crystallin promoter showed complex formation. Gel shift experiments showed binding of recombinant Pax-6 and CREB to their respective sites. Our data suggest convergent evolutionary adaptations that underlie the preferential expression of crystallin genes in the lens of vertebrates and invertebrates.

AN - 71399995; 11791174 AB - Elevation of serum interleukin-6 (IL-6) levels is always associated with alcoholic liver disease (ALD), but the significance of such elevation is not clear. Here we show that chronic ethanol consumption induces significant apoptosis in the liver of IL-6 (-/-) mice but not IL-6 (+/+) mice. IL-6 (-/-) hepatocytes are more susceptible to ethanol- and tumor necrosis factor alpha- (TNFalpha-) induced apoptotic killing, which can be corrected by IL-6. Expression of both anti-apoptotic (such as Bcl-2 and Bcl-x(L)) and proapoptotic (such as Bax) proteins is markedly elevated in the liver of human ALD and chronically ethanol-fed IL-6 (+/+) mice. On the contrary, induction of Bcl-2 and Bcl-x(L) is not observed in the liver of chronically ethanol-fed IL-6 (-/-) mice, whereas expression of Bax protein remains elevated. Injection of IL-6 markedly induces expression of Bcl-2 and Bcl-x(L) but not Bax in the liver. Finally, high concentrations of ethanol inhibit IL-6-activated anti-apoptotic signal, but increasing the concentrations of IL-6 is able to overcome such inhibitory effect. These findings suggest that elevated serum IL-6 levels in ALD may overcome the inhibitory effect of ethanol on IL-6-mediated anti-apoptotic signals and prevent alcohol-induced hepatic apoptosis by induction of Bcl-2 and Bcl-x(L).

The clinical development of target-based anticancer drugs will require fundamental changes to the traditional clinical trial design and end points that have been used for conventional cytotoxic drugs. In the phase I and II settings, traditional end points (toxicity and response) may not be suitable for more selective, cytostatic target-based agents, and these end points may be replaced by biological or pharmacokinetic end points to define the optimal doses and the therapeutic effects of these drugs on their targets. For phase III trials, measurable clinical benefit will continue to be the primary end point. As our understanding of the complex pathways and networks controlling cell signaling, proliferation, and cell death expands, we must learn how and when to use agents to target specific steps in malignant transformation and proliferation, and we must adapt clinical trial design to test the clinical utility of this promising new class of anticancer drugs.

AN - 71536648; 11890469 AB - The field of toxicogenomics, which currently focuses on the application of large-scale differential gene expression (DGE) data to toxicology, is starting to influence drug discovery and development in the pharmaceutical industry. Toxicological pathologists, who play key roles in the development of therapeutic agents, have much to contribute to DGE studies, especially in the experimental design and interpretation phases. The intelligent application of DGE to drug discovery can reveal the potential for both desired (therapeutic) and undesired (toxic) responses. The pathologist's understanding of anatomic, physiologic, biochemical, immune, and other underlying factors that drive mechanisms of tissue responses to noxious agents turns a bewildering array of gene expression data into focused research programs. The latter process is critical for the successful application of DGE to toxicology. Pattern recognition is a useful first step, but mechanistically based DGE interpretation is where the long-term future of these new technologies lies. Pathologists trained to carry out such interpretations will become important members of the research teams needed to successfully apply these technologies to drug discovery and safety assessment. As a pathologist using DGE, you will need to learn to read DGE data in the same way you learned to read glass slides, patiently and with a desire to learn and, later, to teach. In return, you will gain a greater depth of understanding of cell and tissue function, both in health and disease.

AN - 71510661; 11890481 AB - Accuracy of the pathology data is crucial since rodent studies often provide critical data used for setting human chemical exposure standards. Diagnoses represent a judgment on the expected biological behavior of a lesion and peer review can improve diagnostic accuracy and consistency. With the conduct of 500 2-year rodent studies, the National Toxicology Program (NTP) has refined its process for comprehensive review of the pathology data and diagnoses. We have found that careful judgment can improve and simplify the review, whereas simply applying a set review procedure may not assure study quality. The use of reviewing pathologists and pathology peer review groups is a very effective procedure to increase study quality with minimal time and cost. New genomic technology to assess differential gene expression is being used to predict morphological phenotypes such as necrosis, hyperplasia, and neoplasia. The challenge for pathologists is to provide uniform pathology phenotypes that can be correlated with the gene expression changes. The lessons learned in assuring data quality in standard rodent studies also applies to the emerging field of toxicogenomics.

AN - 71343259; 11752114 AB - Conscious squirrel monkeys were treated i.v. with cocaine and various dopamine agonist drugs. Cocaine produced a dose-dependent increase in blood pressure, heart rate, and the rate-pressure product (RPP). The dopamine D1 receptor agonist (+/-)-6-chloro-3-allyl-1-phenyl-2,3,4,5-tetrahydro-1H-3-benzazepine hydrobromide (SKF 82958) produced effects comparable to cocaine. The D1 agonist (+/-)-6-chloro-7, 8-dihydroxy-1-phenyl-2,3,4,5-tetrahydro-1H-3-benzazepine hydrobromide (SKF 81297) also produced increases in blood pressure and heart rate but was much less potent than either cocaine or SKF 82958. The partial D1 agonist (+/-)-7,8-dihydroxy-3-allyl-1-phenyl-2,3,4,5-tetrahydro-1H-3-benzazepine hydrochloride (SKF 77434) did not significantly affect any cardiovascular parameters. The D2 agonist quinpirole slightly decreased blood pressure and increased heart rate. As such, the RPP only slightly increased. The selective dopamine uptake inhibitor 1-[2-[bis-(4-fluorphenyl)methoxy]ethyl]-4-(3-phenylpropyl)piperazine (GBR 12909) produced increases in blood pressure, heart rate, and RPP, but again these effects were smaller and only seen at doses higher than cocaine. Effects similar to those with GBR 12909 were seen with the dopamine autoreceptor antagonist cis-(+)-5-methoxy-1-methyl-2-(di-n-propylamino)tetralin (UH 232). The combination of GBR 12909, SKF 82958, or SKF 77434 with cocaine produced effects that were clearly subadditive. The effects of quinpirole in combination with cocaine were comparable to, or lower than, those of cocaine alone on blood pressure and RPP. The effects on heart rate were additive. Only UH 232 produced additive effects with cocaine for all three measures. As dopamine agonists have been proposed as potential treatments for cocaine abuse, these results suggest that dopamine D1 agonists and uptake inhibitors can be used safely in combination with cocaine. Caution may be warranted, however, with the use of dopamine autoreceptor antagonists in the treatment of cocaine abuse.

AN - 71340590; 11752120 AB - A new nonpeptidic farnesyltransferase inhibitor, RPR-115135, in combination with 5-fluorouracil (5-FU) was studied in an isogenic cell line model system consisting of human colon cancer HCT-116 cells. HCT-116 cells were transfected with an empty control pCMV vector and with a dominant-negative mutated p53 transgene (248R/W). We found that, relative to control transfectants, there was a slight tendency for the p53 inactivated cells to be less sensitive to 5-FU after 6 days of continuous treatment. Simultaneous administration of RPR-115135 and 5-FU, at equitoxic concentrations, resulted in an enhancement of 5-FU cytotoxicity, especially in the CMV-2 clone. Growth inhibition could be accounted for on the basis of a specific cell cycle arrest phenotype (G(2)-M arrest in CMV-2 and S arrest in mutated clones), as assayed by flow cytometry. The combination RPR-115135 + 5-FU increases apoptotic events only in the CMV-2 clone.

We have developed an in vitro meromycolic acid synthase assay to elucidate the anabolic role of these enzymes. Overproduction of KasA and KasB individually and together in M. smegmatis enabled cell-free incorporation of [ super(14)C] malonyl-CoA into lipids whose chain length was dependent upon the M. tuberculosis elongating enzyme used. KasA specifically elongated palmitoyl-CoA to monounsaturated fatty acids that averaged 40 carbons in length. KasB hyperproduction in the presence of KasA produced longer chain multiunsaturated hydrocarbons averaging 54 carbons in length. These products comigrated with a synthetic standard of meromycolic acid and their production was sensitive to isoniazid, thiolactomycin, and triclosan. KasA mutations associated with isoniazid resistance produced an enzyme that had a diminished overall catalytic activity but conferred enhanced resistance to isoniazid. In vivo analysis confirmed that overexpression of each of the four mutant KasAs enhanced isoniazid resistance when compared to overexpression of wild-type KasA. These results suggest discrete anabolic roles for both KasA and KasB in mycolic acid synthesis and substantiate the involvement of KasA mutations in isoniazid resistance.

Hsp90 client proteins include mutated p53, Bcr-Abl, Raf-1, Akt, ErbB2 and hypoxia-inducible factor 1 alpha (HIF-1 alpha ). Hsp90 inhibitors, by interacting specifically with a single molecular target, cause the destabilization and eventual degradation of Hsp90 client proteins, and they have shown promising antitumor activity in preclinical model systems. One Hsp90 inhibitor, 17-allylaminogeldanamycin (17AAG), is currently in phase I clinical trial. Because of the chemoprotective activity of several proteins that are Hsp90 clients, the combination of an Hsp90 inhibitor with a standard chemotherapeutic agent could dramatically increase the in vivo efficacy of the therapeutic agent.
