Accordingly, S. epidermidis does not produce aggressive virulence determinants. Rather, factors that normally sustain the commensal lifestyle of S. epidermidis seem to give rise to additional benefits during infection. Furthermore, we are beginning to comprehend the roles of S. epidermidis in balancing the epithelial microflora and serving as a reservoir of resistance genes. In this Review, I discuss the molecular basis of the commensal and infectious lifestyles of S. epidermidis. C1 NIAID, NIH, Bethesda, MD 20892 USA.

Although the basic mechanisms of random cell movement are well characterized, no single model explains the complex regulation of directional migration. Multiple factors operate at each step of cell migration to stabilize lamellipodia and maintain directional migration. Factors such as the topography of the extracellular matrix, the cellular polarity machinery, receptor signalling, integrin trafficking, integrin co-receptors and actomyosin contraction converge on regulation of the Rho family of GTPases and the control of lamellipodial protrusions to promote directional migration.

The most extensively studied and frequently used immunosuppressive regimens for this disease comprise alkylating agents plus corticosteroids or ciclosporin. All of these treatment options have inherent problems: they are not effective in all patients, partial-rather than complete-remissions are common, adverse effects are worrisome, and relapses after treatment cessation remain problematic. Alternative immunosuppressive agents have been tested in an effort to overcome these unresolved issues. This paper reviews the available evidence regarding both established and new agents for the treatment of patients with idiopathic membranous nephropathy, with an emphasis on the results of the most recent clinical trials.

TI Structural and functional analyses of minimal phosphopeptides targeting the polo-box domain of polo-like kinase 1 SO NATURE STRUCTURAL & MOLECULAR BIOLOGY LA English DT Article ID CENP-A; PLK1; COMPLEX; DIVISION; CELLS AB Polo-like kinase-1 (Plk1) has a pivotal role in cell proliferation and is considered a potential target for anticancer therapy. The noncatalytic polo-box domain (PBD) of Plk1 forms a phosphoepitope binding module for protein-protein interaction. Here, we report the identification of minimal phosphopeptides that specifically interact with the PBD of human PLK1, but not those of the closely related PLK2 and PLK3. Comparative binding studies and analyses of crystal structures of the PLK1 PBD in complex with the minimal phosphopeptides revealed that the C-terminal SpT dipeptide functions as a high-affinity anchor, whereas the N-terminal residues are crucial for providing specificity and affinity to the interaction. Inhibition of the PLK1 PBD by phosphothreonine mimetic peptides was sufficient to induce mitotic arrest and apoptotic cell death. The mode of interaction between the minimal peptide and PBD may provide a template for designing therapeutic agents that target PLK1.

Recent studies have reported that statins have renoprotective effects, independent from lowering plasma cholesterol. In this study, we examined whether statins were beneficial in a murine model of HIV-associated nephropathy (HIVAN). Methods. We used conditional transgenic mice that express one of the HIV-1 accessory genes, vpr, selectively in podocytes using podocin promoter and the Tet-on system. These mice develop aggressive collapsing focal segmental glomerular sclerosis with massive proteinuria and deterioration of renal function within 4 weeks following heminephrectomy and doxycycline administration. Fluvastatin was administrated simultaneously with doxycycline, and the effect was compared with untreated controls after 4 weeks. Results. Fluvastatin at 10 mg/kg/day significantly decreased urinary albumin excretion (87 versus 11 mg/day, P < 0.01) and glomerular sclerosis (2.4 versus 1.0, P < 0.01, assessed by semi-quantitative scoring: 0-4). Fluvastatin also decreased serum creatinine and total cholesterol, but these differences were not statistically significant (0.36 versus 0.32 mg/dl, P = 0.35; 492 versus 378 mg/dl, P = 0.11, respectively). Phenotypic changes in podocytes, as indicated by the downregulation of nephrin, Wilms' tumour 1 and synaptopodin, along with upregulation of proliferating cell nuclear antigen, were attenuated by fluvastatin, suggesting its protective effects against podocyte injuries. In cultured podocytes, angiotensin II treatment decreased nephrin expression to 13% of basal levels, which was reversed to 58% by adding fluvastatin. Conclusions. In conclusion, fluvastatin was effective in treating experimental HIVAN. The beneficial effect of this drug might be caused, in part, by preserving nephrin expression in podocytes against angiotensin II-mediated injury.

We have analyzed FUS/TLS in a cohort of 52 index cases from seven Italian regions with non-SOD1 and non-TARDBP FALS. We identified a heterozygous c.G1542C missense mutation in a family of northern Italian origin, and a heterozygous c.C1574T missense mutation in a family of Sicilian origin. Both variants are located in exon 15 encoding the RNA-recognition motif, and result in a substitution of an arginine with a serine in position 514 (p.R514S) and substitution of a proline with a leucine at position 525 (p.P525L), respectively. Overall, the two mutations accounted for 3.8% of 52 non-SOD1 and non-TDP43 index cases of FALS. The clinical phenotype was similar within each of the families, with a predominantly upper limb onset in the family carrying the p.R514S mutation and bulbar onset, with very young age and a rapid course in the family carrying the p.P525L mutation.

Seven days after a single N-(2-chloroethyl)-N-ethyl-2-bromobenzylamine (DSP-4) intraperitoneal administration in mice, we observed a decrease of NA in both the LC and DRN, as well as in prefrontal cortex (PFC) and hippocampus (HIPP). Moreover, an increase of serotonin (5-HT) and 5-hydroxyindolacetic acid (5-HIAA) was detected at LC level, while no change was found in DRN. DSP-4 also caused a significant decrease of dopamine (DA) tissue content in HIPP and DRN, without affecting the LC and the PFC. A decrease of DA metabolite, homovanillic acid (HVA), was found in the DRN of NA-depleted mice. These results highlight that the neurotoxic action of DSP-4 is not restricted to LC terminal projections but also involves NA depletion at the cell body level, where it is paralleled by adaptive changes in both serotonergic and dopaminergic systems.

TI Relative Efficiencies of Plasma Catechol Levels and Ratios for Neonatal Diagnosis of Menkes Disease SO NEUROCHEMICAL RESEARCH LA English DT Article DE Menkes; Dopamine; Norepinephrine; Dopamine-beta-hydroxylase; DHPG; DOPAC; Diagnosis ID LIQUID-CHROMATOGRAPHY; ELECTROCHEMICAL DETECTION; TYROSINE-HYDROXYLASE; MASS-SPECTROMETRY; DOPAMINE; 5-HYDROXYTRYPTAMINE; NOREPINEPHRINE; PATIENT AB Background Menkes disease is an X-linked recessive neurodevelopmental disorder resulting from mutation in a copper-transporting ATPase gene. Menkes disease can be detected by relatively high concentrations of dopamine (DA) and its metabolites compared to norepinephrine (NE) and its metabolites, presumably because dopamine-beta-hydroxylase (DBH) requires copper as a co-factor. The relative diagnostic efficiencies of levels of catechol analytes, alone or in combination, in neonates at genetic risk of Menkes disease have been unknown. Methods Plasma from 44 at-risk neonates less than 30 days old were assayed for DA, NE, and other catechols. Of the 44, 19 were diagnosed subsequently with Menkes disease, and 25 were unaffected. Results Compared to unaffected at-risk infants, those with Menkes disease had high plasma DA (P < 10(-6)) and low NE (P < 10(-6)) levels. Considered alone, neither DA nor NE levels had perfect sensitivity, whereas the ratio of DA:NE was higher in all affected than in all unaffected subjects (P = 2 x 10(-8)). Analogously, levels of the DA metabolite, dihydroxyphenylacetic acid (DOPAC), and the NE metabolite, dihydroxyphenylglycol (DHPG), were imperfectly sensitive, whereas the DOPAC:DHPG ratio was higher in all affected than in all unaffected subjects (P = 2 x 10(-4)). Plasma dihydroxyphenylalanine (DOPA) and the ratio of epinephrine (EPI):NE levels were higher in affected than in unaffected neonates (P = 0.0015; P = 0.013). Conclusions Plasma DA:NE and DOPAC:DHPG ratios are remarkably sensitive and specific for diagnosing Menkes disease in at-risk newborns. Affected newborns also have elevated DOPA and EPI:NE ratios, which decreased DBH activity alone cannot explain.

TI Variance decomposition of MRI-based covariance maps using genetically informative samples and structural equation modeling SO NEUROIMAGE LA English DT Article ID AUTOMATED 3-D EXTRACTION; CORTICAL THICKNESS; CEREBRAL-CORTEX; HUMAN BRAIN; FUNCTIONAL CONNECTIVITY; VAL66MET POLYMORPHISM; SCHIZOPHRENIA; MULTIVARIATE; NETWORKS; ADOLESCENTS AB The role of genetics in driving intracortical relationships is an important question that has rarely been Studied in humans. In particular, there are no extant high-resolution imaging studies on genetic covariance. In this article, we describe a novel method that combines classical quantitative genetic methodologies for variance decomposition with recently developed semi-multivariate algorithms for high-resolution measurement of phenotypic covariance. Using these tools, we produced correlational maps of genetic and environmental (i.e. nongenetic) relationships between several regions of interest and the cortical surface in a large pediatric sample of 600 twins, siblings, and singletons. These analyses demonstrated high, fairly uniform, statistically significant genetic correlations between the entire cortex and global mean cortical thickness. In agreement with prior reports on phenotypic covariance using similar methods, we found that mean cortical thickness was most strongly correlated with association cortices. However, the present study suggests that genetics plays a large role in global brain patterning of cortical thickness in this manner. Further. using specific gyri with known high heritabilities as seed regions, we found a consistent pattern of high bilateral genetic correlations between structural homologues, with environmental correlations more restricted to the same hemisphere as the seed region, Suggesting that interhemispheric covariance is largely genetically mediated. These findings are consistent with the limited existing knowledge on the genetics of cortical variability as well as our prior multivariate studies on cortical gyri. Published by Elsevier Inc.

Here, we analyze fMRI measurements of the temporal step response to spatially uniform stimuli to estimate these channels ill human primary Visual cortex (VI). In agreement with the psychophysical literature, the VI fMRI temporal responses are modeled accurately as a Mixture of two (transient and sustained) channels. We derive estimates of the relative contributions from these two channels at a range of eccentricities. We find that all portions of VI contain a significant transient response. The central visual field representation includes a significant sustained response, but the amplitude of the sustained channel signal declines with eccentricity. The sustained signals may reflect the emphasis on pattern recognition and color in the central Visual field; the dominant transient response in the Visual periphery may reflect responses in the human Visual attention system.

In this fMRI study we tested whether producing non-speech vocal tract gestures in humans shares the same functional neuroanatomy as non-sense speech syllables. Production of non-speech vocal tract gestures, devoid of phonological content but similar to speech in that they had familiar acoustic and somatosensory targets, was compared to the production of speech syllables without meaning. Brain activation related to overt production was captured with BOLD fMRI using a sparse sampling design for both conditions. Speech and non-speech were compared using voxel-wise whole brain analyses, and ROI analyses focused on frontal and temporoparietal structures previously reported to support speech production. Results showed Substantial activation overlap between speech and non-speech function in regions. Although nonspeech gesture production showed greater extent and amplitude of activation in the regions examined, both speech and non-speech showed comparable left laterality, in activation for both target perception and production. These findings posit a more general role of the previously proposed "auditory dorsal stream" in the left hemisphere - to support the production of vocal tract gestures that are not limited to speech processing.

A previous study in seven patients with ventral prefrontal lesions provided the first direct experimental evidence for abnormalities in social attitudes using a well-established measure of gender stereotypes, the Implicit Association Test (IAT). Here, we were able to test whether these first findings could be reproduced in a larger sample of 154 patients with penetrating head injuries, and to determine the differential effects of ventromedial prefrontal (vmPFC) and ventrolateral prefrontal (vlPFC) cortical lesions on IAT performance. in addition, we investigated the role of the superior anterior temporal lobe (aTL), recently shown to represent conceptual social knowledge. First, we used a linear regression model to identify the role of each of the three regions, while controlling for the extent of damage to other regions. We found that larger lesions in either the vmPFC or the superior aTL were associated with increased stereotypical attitudes, whereas larger lesions in the vlPFC were associated with decreased stereotypical attitudes. Second, in a confirmatory analysis, we grouped patients by lesion location and compared their performance on the IAT with that of healthy volunteers. Compared to controls, patients with lesions in either the vmPFC or the superior aTL showed increased stereotypical attitudes, whereas patients with lesions in the vlPFC showed decreased stereotypical attitudes. The functional contributions of these regions in social attitudes are discussed. Published by Elsevier Ltd.

This study examined in rats the effects of a newly deorphanized neuropeptide receptor and its cognate ligand, Neuropeptide S (NPS), on ethanol consumption and reinstatement of ethanol-seeking by environmental cues previously associated with ethanol availability. In the self-administration experiments, the stable response rates observed for ethanol reinforcement were not modified by intracerebroventricular (ICV) injection of NPS (1.0 and 2.0 nmol per rat). In the reinstatement experiments, ethanol-associated cues induced robust rates of ethanol seeking, which were highly resistant to extinction over repeated sessions of reinstatement testing. ICV NPS treatment (1.0, 2.0 and 4.0 nmol per rat) resulted in a significant increase of ethanol seeking elicited by ethanol-associated cues. In contrast, NPS did not affect the reinstatement of responding to water-paired stimuli. Site-specific NPS injection (0.1 and 0.5 nmol per rat) into the lateral hypothalamus also reinstated extinguished responding to ethanol. This effect was selectively blocked by pre-treatment with the hypocretin-1/orexin-A antagonist SB-334867 (10 mg/kg, i.p.). At the dose tested, SB-334867 did not modify alcohol reinstatement per se. These results provide the first demonstration that activation of NPS receptors in the LH intensifies relapse to ethanol-seeking elicited by environmental conditioning factors. This effect is selective, and is mediated by activation of LH hypocretin neurones. Based on the present findings, we also predict that antagonism at NPS receptors could represent a novel pharmacological approach to alcohol relapse treatment.

The proposed algorithm utilizes information about the degree of homogeneity of the distribution of diffusion tensors within voxels. We adapt frameworks proposed by Hext and Snedecor, where the null hypothesis of diffusion tensors belonging to the same distribution is assessed by an F-test. Tissue type is classified according to one of the four possible diffusion models, the assignment of which is determined by a parsimonious model selection framework based on Schwarz Criterion. Both numerical phantoms and diffusion-weighted imaging (DWI) data obtained from excised rat and pig spinal cords are used to test and validate these tissue clustering and classification approaches. The unsupervised clustering method effectively identifies distinct regions of interest (ROIs) in phantoms and real experimental DTI data. Copyright (C) 2009 John Wiley & Sons, Ltd.

We found a statistically significant decrease in T(1) in the primary (V1) and secondary (V2) areas of the visual cortex caused by an accumulation of manganese. The larger T, shortening in V1 (Delta T(1), = 640 ms) relative to V2 (AT, = 490 ms) allowed us to robustly detect the V1/V2 border in vivo using heavily T(1)-weighted MRI. Furthermore, the dorso-medial (DM) and middle-temporal (MT) areas of the visual pathway could be identified by their T(1)-weighted enhancement. We showed by comparison to histological sections stained for cytochrome oxidase (CO) activity that the extent of V1 is accurately identified throughout the visual cortex by manganese-enhanced MRI (MEMRI). This provides a means of visualizing functional cortical regions in vivo and could be used in longitudinal studies of phenomena such as cortical plasticity, and for non-destructive localization of cortical regions to guide in the implementation of functional techniques.

The relationship between serum vitamin D concentrations and mortality in older community-dwelling women has not been well characterized. We hypothesized that women with lower 25-hydroxyvitamin D (25[OH]D) concentrations were at higher risk of mortality. We examined the association between serum 25[OH]D concentrations and all-cause mortality in a prospective, population-based study of 714 community-dwelling women, aged 70 to 79 years, the Women's Health and Aging Studies I and 11 in Baltimore, Md. The studies were originally designed to evaluate the causes and course of physical disability in older women living in the community. Vital status was determined through follow-up interviews and matching with the National Death Index. During a median of 72 months of follow-up, 100 (14%) of 714 women died. Women in the lowest quartile of 25(OH)D (<15.3 ng/mL or 38.2 nmol/L) were at higher risk of death (hazards ratio, 2.45; 95% confidence interval, 1.12-5.36; P = .02) compared to women in the highest quartile (>27.0 ng/mL or 67.4 nmol/L) of 25(OH)D in a multivariate Cox proportional hazards model adjusting for demographics, season, and conventional risk factors. Older community-dwelling women with low 25 (OH)D levels are at an increased risk of death. (C) 2009 Elsevier Inc. All rights reserved.

METHODS: This was a prospective, 2-year observational study at 13 academic medical centers conducted between January 1, 1999, and December 31, 2000, on all women who underwent a hysterectomy at the time of cesarean delivery. Data were abstracted from the medical record by study nurses. The outcomes included procedure frequency, indications, and complications. RESULTS: A total of 186 cesarean hysterectomies (0.5%) were performed from a cohort of 39,244 women who underwent cesarean delivery. The leading indications for hysterectomy were placenta accreta (38%) and uterine atony (34%). Of the hysterectomy cases with a diagnosis recorded as accreta, 18% accompanied a primary cesarean delivery, and 82% had a prior procedure (P<.001). Of the hysterectomy cases with atony recorded as a diagnosis, 59% complicated primary cesarean delivery, whereas 41% had a prior cesarean (P<.001). Major maternal complications of cesarean hysterectomy included transfusion of red blood cells (84%) and other blood products (34%), fever (11%), subsequent laparotomy (4%), ureteral injury (3%), and death (1.6%). Accreta hysterectomy cases were more likely than atony hysterectomy cases to require ureteral stents (14% compared with 3%, P=.03) and to instill sterile milk into the bladder (23% compared with 8%, P=.02). CONCLUSION: The rate of cesarean hysterectomy has declined modestly in the past decade. Despite the use of effective therapies and procedures to control hemorrhage at cesarean delivery, a small proportion of women continue to require hysterectomy to control hemorrhage from both uterine atony and placenta accreta.

TI Degreasing and risk of non-Hodgkin lymphoma SO OCCUPATIONAL AND ENVIRONMENTAL MEDICINE LA English DT Article ID UNITED-STATES; OCCUPATION; EXPOSURES AB Objective: To investigate the relationship between selected solvent-related workplace tasks (degreasing, painting, gluing, stripping paint, staining) and risk of non-Hodgkin lymphoma (NHL). Methods: We analysed occupational data from a large population-based case-control study of NHL conducted in the USA. For participants reporting occupations with possible exposure to organic solvents, job-specific interview modules were administered to elicit in-depth information on solvent-related workplace tasks and other exposure-related factors (225 cases, 189 controls). Unconditional logistic regression models were fit to calculate odds ratios (ORs) and 95% CI for average frequency, maximal frequency and cumulative number of hours having performed each task. Individuals with jobs rated as unexposed to organic solvents in the workplace (180 cases, 213 controls) were used as a reference group. Results: We observed an increased risk of NHL among subjects in the highest category of maximal degreasing frequency (>520 h/year: OR 2.1, 95% CI 0.9 to 4.9, trend test p = 0.02). We found similar associations for the highest levels of average frequency and, among men, cumulative number of hours. Other solvent-related tasks were not associated with NHL. Conclusion: Findings from this case-control analysis of solvent-related tasks suggest that frequent degreasing work may be associated with an elevated risk of NHL. C1 [Purdue, M.

TI Epidemiology and Course of Disease in Childhood Uveitis SO OPHTHALMOLOGY LA English DT Article ID PEDIATRIC UVEITIS; CHILDREN AB Purpose: To describe the disease characteristics and visual outcome of pediatric uveitis. Design: Retrospective, longitudinal observation. Participants. Five hundred twenty-seven pediatric uveitis patients from the National Eye Institute, University of Illinois, Chicago, and Oregon Health Sciences University. Methods: Retrospective chart review. Main Outcome Measures: Demographics, uveitis disease characteristics, complications, treatments, and visual outcomes were determined at baseline and at 1-, 3-, 5-, and 10-year time points. Results: The patient population was 54% female; 62.4% white, 12.5% black, 2.7% Asian, 2.1% multiracial, and 14.61% Hispanic. Median age at diagnosis was 9.4 years. The leading diagnoses were idiopathic uveitis (28.8%), juvenile idiopathic arthritis-associated uveitis (20.9%), and pars planitis (17.1%). Insidious onset (58%) and persistent duration (75.3%) were most common. Anterior uveitis was predominant (44.6%). Complications were frequent, and cystoid macular edema (odds ratio [OR] 2.94; P = 0.006) and hypotony (OR, 4.54; P = 0.026) had the most significant visual impact. Ocular surgery was performed in 18.9% of patients. The prevalence of legal blindness was 9.23% at baseline, 6.52% at 1 year, 3.17% at 3 years, 15.15% at 5 years, and 7.69% at 10 years. Posterior uveitis and panuveitis had more severe vision loss. Hispanic ethnicity was associated with a higher prevalence of infectious uveitis and vision loss at baseline. Conclusions: The rate and spectrum of vision threatening complications of pediatric uveitis are significant. Prospective studies using standard outcome measures and including diverse populations are needed to identify children most at risk.

In the west, smoking and alcohol consumption are considered to be the main risk factors whilst in India and southeast Asia, betel quid (BQ) chewing is predominant. In this study, we compared the gene expression patterns of oral cancers associated with BQ chewing to those caused by smoking using Affymetrix microarrays. We found that 281 genes were differentially expressed between OSCC and normal oral mucosa regardless of aetiological factors including MMP1, PLAU, MAGE-D4, GNA12, IFITM3 and NMU. Further, we identified 168 genes that were differentially expressed between the BQ and smoking groups including CXCL-9, TMPRSS2, CA12 and RNF24. The expression of these genes was validated using qPCR using independent tissue samples. The results demonstrate that whilst common genes/pathways contribute to the development of oral cancer, there are also other gene expression changes that are specific to certain risk factors. The findings suggest that different carcinogens activate or inhibit specific pathways during cancer development and progression. These unique gene expression profiles should be taken into consideration when developing biomarkers for future use in prognostic or therapeutic applications. (C) 2008 Elsevier Ltd.

Background information is presented to illustrate influences affecting genetic research studies of Mendelian diseases. Genetic studies of amelogenesis imperfecta, dentinogenesis imperfecta, hereditary gingival fibromatosis and Papillon Lefevre syndrome are reviewed. Findings are presented to illustrate how translational applications of clinical and basic research may improve clinical care. Clinical and basic science research has identified specific genes and mutations etiologically responsible for amelogenesis imperfecta, dentinogenesis imperfecta, hereditary gingival fibromatosis and Papillon Lefevre syndrome. These findings are enabling researchers to understand how specific genetic alterations perturb normal growth and development of dental tissues. Identification of the genetic basis of these conditions is enabling clinicians and researchers to more fully understand the etiology and clinical consequences of these diseases of dental importance. Findings from genetic studies of dental diseases provide a basis for diagnostic genetic testing and development of therapeutic intervention strategies directed at the underlying disease etiology. These studies are advancing our understanding of the development of dental tissues in health and disease. The dental community must consider how to incorporate these developments into effective disease prevention paradigms to facilitate the diagnosis and treatment of individuals with genetic diseases.

Studies in mice demonstrate that vertical transmission of T. gondii is common and that chronically infected mice can transmit T. gondii to successive generations. In this study, PCR and immunohistochemistry were used to detect T. gondii in chronically infected marsupial dams and their offspring. T. gondii was detected in the unfurred pouch young of 2 out of 10 chronically infected western grey kangaroos (Macropus fuliginosus) and in the unfurred pouch young of a brush-talied bettong (Bettongia penicillata). Results of the study suggest that vertical transmission of T. gondii can occur in chronically infected Australian marsupials. C1 [Parameswaran, N.; Thompson, R. C.

Multiple system atrophy (MSA) is a non-Lewy body disease in which alpha-synuclein accumulates in glial cells, with central catecholamine deficiency but preserved cardiac sympathetic innervation in most patients. PD is associated with more severe and consistent olfactory dysfunction than in MSA; whether PAF entails olfactory dysfunction has been unknown. In this study we assessed olfactory function in PAF in comparison with the two other synucleinopathies and whether olfactory dysfunction correlates with neuroimaging evidence of cardiac noradrenergic or nigrostriatal dopaminergic denervation. Method: The University of Pennsylvania Smell Identification Test (UPSIT) was administered to 8 patients with PAF, 23 with PD, and 20 with MSA. 6-[(18)F]Fluorodopamine positron emission tomographic (PET) scanning was used to indicate cardiac noradrenergic innervation and the putamen:occipital cortex (PUT:OCC) and substantia nigra (SN):OCC ratios of 6-[(18)F]fluorodopa-derived radioactivity to indicate nigrostriatal dopaminergic innervation. Results: The PAF group had a low mean UPSIT score (22 +/- 3), similar to that in PD (20 +/- 2) and lower than in MSA (31 +/- 2, p = 0.004). Individual UPSIT scores correlated positively with cardiac 6-[(18)F]fluorodopamine-derived radioactivity (r = 0.63 in the septum, p < 0.0001; r = 0.64 in the free wall, p < 0.0001) but not with PUT:OCC or SN:OCC ratios of 6-[(18)F]fluorodopa-derived radioactivity. Discussion: in synucleinopathies, olfactory dysfunction is related to Lewy body pathology and cardiac sympathetic denervation, independently of parkinsonism or striatal dopamine deficiency.

TI Symptomatic and Pathophysiologic Predictors of Hepatitis C Virus Progression in Pediatric Patients SO PEDIATRIC INFECTIOUS DISEASE JOURNAL LA English DT Article DE symptoms; fibrosis; cirrhosis; comorbidity; hepatitis C ID CLINICAL SPECTRUM; CHILDHOOD-CANCER; CHILDREN; INFECTION; TRANSFUSION; SURVIVORS; FEATURES; DISEASE; LIVER AB Background: The slow progression of hepatitis C virus (HCV) infection could ultimately negatively impact pediatric patients during their lifespan. This study describes the symptomatic and pathophysiologic presentation of HCV infection in a cohort of pediatric outpatients. Methods: HCV-positive patients were identified by diagnosis codes, from outpatient visits. Demographic and pathophysiologic indicators (comorbidities, reported symptoms, alanine transaminase, aspartate transaminase, gamma glutamyl transpeptidase, HCV viral load, genotype, and liver biopsy results) were collected and analyzed. Results: We reviewed 62 patients with HCV infection who were from 3 months and 19 years of age (M +/- SD, 12.5 +/- 5.8 years). Sixty percent presented with clinical symptoms of fatigue, Joint-abdominal pain, bruising/bleeding, or other non-specific symptoms. On liver biopsy (n=35) 80% had evidence of inflammation, 57% had fibrosis, and 9% had steatosis. All patients with steatosis or cirrhosis reported symptoms. Males were significantly more likely than women to be symptomatic (58.3% vs. 41.7%, P=0.04). Patients with symptoms were significantly older (M=13.5 +/- 5.2 vs. 8.9 +/- 5.5 years, P=0.003). There was a significant inverse relationship between viral load and symptoms (chi(2) = 4.7.5, P = 0.03). Patients with low viral load (<2 million copies) were 5 times more likely to have symptoms than those with high viral loads (P = 0.03). Significance was also noted between HCV genotype and ALT levels (chi(2) = 3.72, P = 0.05). There were no significant relationships between symptom status and race, comorbidities. alaninie transaminase, aspartate transaminase, gamma glutamyl transpeptidase, HCV genotype, or liver histology. Conclusion: Pediatric patients with HCV can have significant symptoms and physiologic liver changes related to HCV.

CA IMPAACT P1055 Study Team TI Mental Health Treatment Patterns in Perinatally HIV-Infected Youth and Controls SO PEDIATRICS LA English DT Article; Proceedings Paper CT 68th Annual Meeting of the Society-for-Applied-Anthropology CY MAR 25-29, 2008 CL Memphis, TN SP Soc Appl Anthropol DE HIV; psychiatric disorders; treatment ID PSYCHIATRIC-DISORDERS; PSYCHOTROPIC MEDICATION; SOCIAL SUPPORT; HAART ERA; CHILDREN; ADOLESCENTS; HIV/AIDS AB BACKGROUND: Youths perinatally infected with HIV often receive psychotropic medication and behavioral treatment for emotional and behavioral symptoms. We describe patterns of intervention for HIV-positive youth and youth in a control group in the United States. METHODS: Three hundred nineteen HIV-positive youth and 256 controls, aged 6 to 17 years, enrolled in the International Maternal Adolescent AIDS Clinical Trials 1055, a prospective, 2-year observational study of psychiatric symptoms. One hundred seventy-four youth in the control group were perinatally exposed to HIV, and 82 youth were uninfected children living in households with HIV-positive members. Youth and their primary caregivers completed Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition-referenced symptom-rating scales. Children's medication and behavioral psychiatric intervention histories were collected at entry. We evaluated the association of past or current psychiatric treatment with HIV status, baseline symptoms, and impairment by using multiple logistic regression, controlling for potential confounders. RESULTS: HIV-positive youth and youth in the control group had a similar prevalence of psychiatric symptoms (61%) and impairment (14% to 15%). One hundred four (18%) participants received psychotropic medications (stimulants [14%], antidepressants [6%], and neuroleptic agents [4%]), and 127 (22%) received behavioral treatment. More HIV-positive youth than youth in the control group received psychotropic medication (23% vs 12%) and behavioral treatment (27% vs 17%). After adjusting for symptom class and confounders, HIV-positive children had twice the odds of children in the control group of having received stimulants and >4 times the odds of having received antidepressants. Caregiver-reported symptoms or impairment were associated with higher odds of intervention than reports by children alone. CONCLUSIONS: HIV-positive children are more likely to receive mental health interventions than control-group children. Pediatricians and caregivers should consider available mental health treatment options for all children living in families affected by HIV.

TI Characterization of putative GRP- and NMB-receptor antagonist's interaction with human receptors SO PEPTIDES LA English DT Article DE Human; Gastrin-releasing peptide; Neuromedin B; Bombesin-related peptide; Bombesin ID GASTRIN-RELEASING-PEPTIDE; NEUROMEDIN-B-RECEPTOR; MAMMALIAN BOMBESIN RECEPTORS; HUMAN ORPHAN RECEPTOR; CELL LUNG-CANCER; HIGH-AFFINITY; ANTIMITOTIC ACTIVITY; PANCREATIC ACINAR; CARCINOMA CELLS; GROWTH-FACTORS AB The mammalian bombesin (Bn) peptides neuromedin B (NMB) and gastrin-releasing peptide (GRP) actions are mediated by two receptors (NMB-receptor, GRP-receptor) which are widely distributed in the GI tract and CNS. From primarily animal studies NMB/GRP-receptor activation has physiological/pathophysiological effects in the CNS and GI tract including stimulating of growth of cancers and normal tissues. Whereas these Bn-receptors' effects have been extensively studied in nonhuman cells and animals, little is known of the physiological/pathological role(s) in humans, largely due to lack of potent antagonists. To address this issue we compared NMB/GRP-receptor affinity/potency of 10 chemical classes of putative antagonists (35 compounds) for human Bn-receptors by performing binding studies or assessing abilities to activate hGRP/hNMB-receptor [assessing phospholipase C activation] in four different cells containing native Bn-receptors or transfected receptors. From binding studies 23 were GRP-receptor-preferring, 4 were NMB-receptor, and 8 nonselective. For the hGRP-receptor-preferring analogues none showed hGRP-receptor agonist activity, but 13 were full or partial hNMB-receptor agonists at hNMB-receptors. For hNMB-receptor-preferring analogues none were agonists. Analogue #24 ([(3-Ph-Pr(6)), His(7), D-Ala(11), D-Pro(13), Psi(13-14), Phe(14)]Bn(6-14)NH(2)) and analogue #7 [D-Phe(6), Leu(13), Psi(CH(2)NH), Cpa(14)]Bn(6-14) were the most potent (0.2-1.4 nM) and selective (>10,000-fold) for the hGRP-receptor with analogue #7.5 [D-Tpi(6), Leu(13), Psi(CH(2)NH), Leu(14)]Bn(6-14)[RC-3095] (0.2-1.4 nM) slightly less selective. Analogue #34 (PD168368) had the highest affinity for hNMB-receptor (1.32-1.58 nM) and the greatest selectivity (2298-6952-fold) for the hNMB-receptor. These results demonstrate numerous putative hGRP/hNMB-receptor antagonists identified in nonhuman cells and/or animals have agonist activity at the hNMB-receptor. limiting their potential usefulness. However, a number were identified which were potent/selective for human Bn-receptors and should be useful for investigating their roles in human physiological/pathophysiological conditions.

Extraction employed a low ionic strength rigor solution, followed by sequential reconstitution at physiological ionic strength with Tm then Tn. SDS-PAGE analysis was consistent with full reconstitution, and fluorescence imaging after reconstitution using Oregon-green-labeled Tm indicated the expected localization. Myofibrils remained mechanically viable: maximum isometric forces of myofibrils after sTm/sTn reconstitution (control) were comparable (similar to 84%) to the forces generated by non-reconstituted preparations, and the reconstitution minimally affected the rate of isometric activation (k (act)), calcium sensitivity (pCa(50)), and cooperativity (n (H)). Reconstitutions using various combinations of cardiac and skeletal Tm and Tn indicated that isoforms of both Tm and Tn influence calcium sensitivity of force development in opposite directions, but the isoforms do not otherwise alter cross-bridge kinetics. Myofibrils reconstituted with Delta 23Tm, a deletion mutant lacking the second and third of Tm's seven quasi-repeats, exhibited greatly depressed maximal force, moderately slower k (act) rates and reduced n (H). Delta 23Tm similarly decreased the cooperativity of calcium binding to the troponin regulatory sites of isolated thin filaments in solution. The mechanisms behind these effects of Delta 23Tm also were investigated using P (i) and ADP jumps. P (i) and ADP kinetics were indistinguishable in Delta 23Tm myofibrils compared to controls. The results suggest that the deleted region of tropomyosin is important for cooperative thin filament activation by calcium. C1 [Siththanandan, V.

AB In 1999, the Department of Medicinal Chemistry and Pharmacognosy at the College of Pharmacy, University of Illinois (UIC) at Chicago was funded to establish a Botanical Dietary Supplements Research Center from the National Institutes of Health (NIH). The emphasis of the UIC/NIH Center for Botanical Dietary Supplements Research (CBDSR) is botanical dietary supplements (BDS) for women's health. The Center's research has focused on BDS that may improve women's health and quality of life, specifically in the areas of menopause, premenstrual syndrome, and persistent urinary tract infections. Center investigators have overcome many challenges associated with botanical dietary supplements research, including acquiring and identifying plant species for investigation, isolating and identifying active constituents, elucidating the mechanisms of action of these botanicals, and conducting Phase I and Phase 11 clinical studies. Black cohosh [Actaea racemosa L. (Ranunculaceae)] has been used as a model to illustrate the steps involved in taking a botanical dietary supplement from the field, all the way to clinical trials. Bioassays are described that were necessary to elucidate the pertinent biological studies of plant extracts and their mechanisms of action. The Center has used an innovative multidisciplinary approach to this type of research, and thus has been very successful in fulfilling its specific aims.

By 2007, the program had completed three cycles of funding. In the last cycle (2003-2008), seven ICBGs were operating in biodiversity hotspots around the world with support from nine Institutes and Centers of the National Institutes of Health and from the National Science Foundation and the US Department of Agriculture. Accomplishments over the history of the program include discovery of numerous bioactive compounds, training of thousands of young scientists in the US and abroad, and the creation and enhancement of biodiversity protected areas around the world. Over the history of the ICBG program plant-based research has been a significant component of many projects. Over 10,000 species of tropical, temperate and arid lands plants from 350 plant families have been analyzed. While some of the research has been guided by ethnobotanical science, particularly science oriented toward botanical medicines, much has been focused around diversity-oriented collections, and some have used ecological principles to identify active compounds.While marine and microbial organisms have grown in importance among the natural products research community, plants will continue to play important roles for the foreseeable future.

Accumulating evidence implicates dysregulation of the endocannabinoid system (ECS) in the pathogenesis of various cardiovascular diseases, including hypertension, atherosclerosis, myocardial infarction, hemorrhagic or septic shock, heart failure and cardiovascular complications of liver cirrhosis. Even though the benefit of chronic cannabinoid 1 (CB1) receptor blockade with the currently available compounds may not outweigh the risks in chronic conditions such as obesity, modulation of the ECS may hold great therapeutic promise in various cardiovascular conditions/disorders. In this review we will discuss recent advances in understanding the role of CB, receptors and endocannabinoids in the regulation of cardiac function in cirrhotic carchomyopathy and in doxorubicin-induced heart failure.

In addition, increased risk of suicide attempts is a major public health concern during the first month of standard antidepressant therapy. Thus, improved therapeutics that can exert their antidepressant effects within hours or a few days of their administration are urgently needed, as is a better understanding of the presumed mechanisms associated with these rapid antidepressant effects. In this context, the N-methyl-D-aspartate (NMDA) antagonist ketamine has consistently shown antidepressant effects within a few hours of its administration. This makes it a valuable research tool to identify biomarkers of response in order to develop the next generation of fast-acting antidepressants. In this review, we describe clinical, electrophysiological, biochemical, and imaging correlates as relevant targets in the study of the antidepressant response associated with ketamine, and their implications for the development of novel, fast-acting antidepressants. We also review evidence that alpha-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) to NMDA throughput may represent a convergent mechanism for the rapid antidepressant actions of ketamine. Overall, understanding the molecular basis of this work will likely lead to the ultimate development of improved therapeutics for MDD. Published by Elsevier Inc.

This article focuses on current and future intervention strategies for improving mobility and participation during the lifespan for ambulatory children with CP. The provision and integration of physical therapy and medical and orthopedic surgery management focused primarily on the lower extremities are discussed here. Some of the newer trends are more intense and task-related exercise strategies, greater precision in tone identification and management, and a shift towards musculoskeletal surgery that focuses more on promoting dynamic bony alignment and less on releasing or lengthening tendons. Advances in basic and clinical science and technology development are changing existing paradigms and offering renewed hope for improved functioning for children with CP who face a lifelong disability with unique challenges at each stage in life.

TI Entropic effects in channel-facilitated transport: Interparticle interactions break the flux symmetry SO PHYSICAL REVIEW E LA English DT Article DE biotransport; Brownian motion; diffusion; entropy ID PORE AB We analyze transport through conical channels that is driven by the difference in particle concentrations on the two sides of the membrane. Because of the detailed balance, fluxes of noninteracting particles through the same channel, inserted into the membrane in two opposite orientations, are equal. We show that this flux symmetry is broken by particle-particle interactions so that one of the orientations can be much more efficient for transport under the same external conditions. The results are obtained analytically using a one-dimensional diffusion model and confirmed by three-dimensional Brownian dynamics simulations.

Because of the close relation between percolation and epidemic spread, the behavior of percolation in such networks gives insight into infectious disease dynamics. A number of authors have studied percolation or epidemics in clustered networks, but the networks often contain preferential contacts in high degree nodes. We introduce a class of random clustered networks and a class of random unclustered networks with the same preferential mixing. Percolation in the clustered networks reduces the component sizes and increases the epidemic threshold compared to the unclustered networks.

First published June 23, 2009; doi: 10.1152/physiolgenomics.00083.2009.-Copper is an essential trace element; however, at supraphysiological levels, it can be extremely toxic. Microarray data from HepG2 cells exposed to 100, 200, 400, and 600 mu M copper for 4, 8, 12 and 24 h were generated and analyzed. Principal components, K-means, and hierarchical clustering, interactome, and pathway mapping analyses indicated that these exposure conditions induce physiological and toxicological changes in the HepG2 transcriptome. As a general trend, when the level of toxicity increases, the number and diversity of affected genes, Gene Ontology categories, regulatory pathways, and complexity of interactomes increase. Physiological responses to copper include transition metal ion binding and responses to stress/stimulus, whereas toxicological responses include apoptosis, morphogenesis, and negative regulation of biomolecule metabolism. The global gene expression profile was overlaid onto biomolecular interaction networks and signal transduction cascades using pathway mapping and interactome identification. This analysis indicated that copper modulates signal transduction pathways associated with MAPK, NF-kappa B, death receptor, IGF-I, hypoxia, IL-10, IL-2, IL-6, EGF, Toll-like receptor, protein ubiquitination, xenobiotic metabolism, leukocyte extravasation, complement and coagulation, and sonic hedgehog signaling. These results provide insights into the global and molecular mechanisms regulating the physiological and toxicological responses to metal exposure.

The rapid metabolic response of phosphoinositides after stimulation of certain cell surface receptors was the first indication that these lipids could serve as regulatory molecules. These early observations opened research areas that ultimately clarified the plasma membrane role of phosphoinositides in Ca2+ signaling. However, research of the last 10 years has revealed a much broader range of processes dependent on phosphoinositides. These lipids control organelle biology by regulating vesicular trafficking, and they modulate lipid distribution and metabolism more generally via their close relationship with lipid transfer proteins. Phosphoinositides also regulate ion channels, pumps, and transporters as well as both endocytic and exocytic processes. The significance of phosphoinositides found within the nucleus is still poorly understood, and a whole new research concerns the highly phosphorylated inositols that also appear to control multiple nuclear processes. The expansion of research and interest in phosphoinositides naturally created a demand for new approaches to determine where, within the cell, these lipids exert their effects. Imaging of phosphoinositide dynamics within live cells has become a standard cell biological method. These new tools not only helped us localize phosphoinositides within the cell but also taught us how tightly phosphoinositide control can be linked with distinct effector protein complexes. The recent progress allows us to understand the underlying causes of certain human diseases and design new strategies for therapeutic interventions.

To determine whether MITF is somatically mutated in melanoma, we compared the sequence of MITF from primary and metastatic lesions to patient-matched normal DNA. In the 50 metastatic melanoma tumor lines analysed, we discovered four samples that had genomic amplifications of MITF and four that had MITF mutations in the regions encoding the transactivation, DNA binding or basic, helix-loop-helix domains. Sequence analysis for SOX10, a transcription factor, which both acts upstream of MITF and synergizes with MITF, identified an additional three samples with frameshift or nonsense mutations. Microphthalmia-associated transcription factor and SOX10 were found to be mutated in a mutually exclusive fashion, possibly suggesting disruption in a common genetic pathway. Taken together we found that over 20% of the metastatic melanoma cases had alterations in the MITF pathway. We show that the MITF pathway is also altered in primary melanomas: 2/26 demonstrated mutations in MITF and 6/55 demonstrated mutations in SOX10. Our findings suggest that altered MITF function during melanomagenesis can be achieved by MITF amplification, MITF single base substitutions or by mutation of its regulator SOX10.

They exhibit apical and basal processes that contact the ventricular surface and the pial basement membrane, respectively. This unique architecture is important for VZ physical integrity and fate determination of NSC daughter cells. In addition, the shorter apical process is critical for interkinetic nuclear migration (INM), which enables VZ cell mitoses at the ventricular surface. Despite their importance, the mechanisms required for NSC adhesion to the ventricle are poorly understood. We have shown previously that one class of candidate adhesion molecules, laminins, are present in the ventricular region and that their integrin receptors are expressed by NSC. However, prior studies only demonstrate a role for their interaction in the attachment of the basal process to the overlying pial basement membrane. Here we use antibody-blocking and genetic experiments to reveal an additional and novel requirement for laminin/integrin interactions in apical process adhesion and NSC regulation. Transient abrogation of integrin binding and signalling using blocking antibodies to specifically target the ventricular region in utero results in abnormal INM and alterations in the orientation of NSC divisions. We found that these defects were also observed in laminin alpha 2 deficient mice. More detailed analyses using a multidisciplinary approach to analyse stem cell behaviour by expression of fluorescent transgenes and multiphoton time-lapse imaging revealed that the transient embryonic disruption of laminin/integrin signalling at the VZ surface resulted in apical process detachment from the ventricular surface, dystrophic radial glia fibers, and substantial layering defects in the postnatal neocortex. Collectively, these data reveal novel roles for the laminin/integrin interaction in anchoring embryonic NSCs to the ventricular surface and maintaining the physical integrity of the neocortical niche, with even transient perturbations resulting in long-lasting cortical defects.

TI Osteo-Chondroprogenitor-Specific Deletion of the Selenocysteine tRNA Gene, Trsp, Leads to Chondronecrosis and Abnormal Skeletal Development: A Putative Model for Kashin-Beck Disease SO PLOS GENETICS LA English DT Article ID THYROID-HORMONE; THIOREDOXIN REDUCTASE; GROWTH-PLATE; BONE; SELENIUM; MOUSE; SELENOPROTEINS; IODINE; DEFICIENCY; METABOLISM AB Kashin-Beck disease, a syndrome characterized by short stature, skeletal deformities, and arthropathy of multiple joints, is highly prevalent in specific regions of Asia. The disease has been postulated to result from a combination of different environmental factors, including contamination of barley by mold mycotoxins, iodine deficiency, presence of humic substances in drinking water, and, importantly, deficiency of selenium. This multifunctional trace element, in the form of selenocysteine, is essential for normal selenoprotein function, including attenuation of excessive oxidative stress, and for the control of redox-sensitive molecules involved in cell growth and differentiation. To investigate the effects of skeletal selenoprotein deficiency, a Cre recombinase transgenic mouse line was used to trigger Trsp gene deletions in osteo-chondroprogenitors. Trsp encodes selenocysteine tRNA([Ser]Sec), required for the incorporation of selenocysteine residues into selenoproteins. The mutant mice exhibited growth retardation, epiphyseal growth plate abnormalities, and delayed skeletal ossification, as well as marked chondronecrosis of articular, auricular, and tracheal cartilages. Phenotypically, the mice thus replicated a number of the pathological features of Kashin-Beck disease, supporting the notion that selenium deficiency is important to the development of this syndrome.

TI Genome-Wide Association Study Implicates Chromosome 9q21.31 as a Susceptibility Locus for Asthma in Mexican Children SO PLOS GENETICS LA English DT Article ID CASE-PARENT TRIADS; LINKAGE DISEQUILIBRIUM; CHILDHOOD ASTHMA; PUERTO-RICAN; ADMIXTURE; GENES; RUNX3; AMERICAN; HOMOLOGS; PROTEINS AB Many candidate genes have been studied for asthma, but replication has varied. Novel candidate genes have been identified for various complex diseases using genome-wide association studies (GWASs). We conducted a GWAS in 492 Mexican children with asthma, predominantly atopic by skin prick test, and their parents using the Illumina HumanHap 550 K BeadChip to identify novel genetic variation for childhood asthma. The 520,767 autosomal single nucleotide polymorphisms (SNPs) passing quality control were tested for association with childhood asthma using log-linear regression with a log-additive risk model. Eleven of the most significantly associated GWAS SNPs were tested for replication in an independent study of 177 Mexican case-parent trios with childhood-onset asthma and atopy using log-linear analysis. The chromosome 9q21.31 SNP rs2378383 (p = 7.10 x 10(-6) in the GWAS), located upstream of transducin-like enhancer of split 4 (TLE4), gave a p-value of 0.03 and the same direction and magnitude of association in the replication study (combined p = 6.79 x 10(-7)). Ancestry analysis on chromosome 9q supported an inverse association between the rs2378383 minor allele (G) and childhood asthma. This work identifies chromosome 9q21.31 as a novel susceptibility locus for childhood asthma in Mexicans. Further, analysis of genome-wide expression data in 51 human tissues from the Novartis Research Foundation showed that median GWAS significance levels for SNPs in genes expressed in the lung differed most significantly from genes not expressed in the lung when compared to 50 other tissues, supporting the biological plausibility of our overall GWAS findings and the multigenic etiology of childhood asthma.

TI Cooperative Blood-feeding and the Function and Implications of Feeding Aggregations in the Sand Fly, Lutzomyia longipalpis (Diptera: Psychodidae) SO PLOS NEGLECTED TROPICAL DISEASES LA English DT Article ID LEISHMANIA VIANNIA BRAZILIENSIS; AMERICAN VISCERAL LEISHMANIASIS; MOSQUITO-MEDIATED ATTRACTION; CUTANEOUS LEISHMANIASIS; VASODILATORY PEPTIDE; SALIVARY-GLANDS; HOST BEHAVIOR; MAXADILAN; SUCCESS; INFECTION AB Given the importance that the evolution of cooperation bears in evolutionary biology and the social sciences, extensive theoretical work has focused on identifying conditions that promote cooperation among individuals. In insects, cooperative or altruistic interactions typically occur amongst social insects and are thus explained by kin selection. Here we provide evidence that in Lutzomia longipalpis, a small biting fly and an important vector of leishmaniasis in the New World, cooperative blood-feeding in groups of non-kin individuals results in a strong decrease in saliva expenditure. Feeding in groups also strongly affected the time taken to initiate a bloodmeal and its duration and ultimately resulted in greater fecundity. The benefits of feeding aggregations were particularly strong when flies fed on older hosts pre-exposed to sand fly bites, suggesting that flies feeding in groups may be better able to overcome their stronger immune response. These results demonstrate that, in L. longipalpis, feeding cooperatively maximizes the effects of salivary components injected into hosts to facilitate blood intake and to counteract the host immune defences. As a result, cooperating sand flies enjoy enormous fitness gains. This constitutes, to our knowledge, the first functional explanation for feeding aggregations in this species and potentially in other hematophagous insects and a rare example of cooperation amongst individuals of a nonsocial insects species. The evolution of cooperative group feeding in sand flies may have important implications for the epidemiology of leishmaniasis.

TI Advancing the hypothesis that geographic variations in risk factors contribute relatively little to observed geographic variations in heart disease and stroke mortality SO PREVENTIVE MEDICINE LA English DT Article DE Stroke; Coronary heart disease; Geography; Risk factors; Mortality ID SOUTHEASTERN UNITED-STATES; HYPERTENSION; PREDICTION; PROFILE; BELT AB Purpose. Geographic variation in risk factors may underlie geographic disparities in coronary heart disease (CHD) and stroke mortality. Methods. Framingham CHD Risk Score (FCRS) and Stroke Risk Score (FSRS) were calculated for 25,770 stroke-free and 22,247 CHD-free participants from the REasons for Geographic And Racial Differences in Stroke cohort. Vital statistics provided age-adjusted CHD and stroke mortality rates. In an ecologic analysis, the age-adjusted, race-sex weighted, average state-level risk factor levels were compared to state-level mortality rates. Results. There was no relationship between CHD and stroke mortality rates (r=0.04; p=0.78), but there was between CHD and stroke risk scores at the individual (r=0.68: p<0.0001) and state (r=0.64, p<0.0001) level. There was a stronger (p<0.0001) association between state-level FCRS and state-level CHD mortality (r=0.28, p=0.18), than between FSRS and stroke mortality (r=0.12, p=0.56). Conclusions. weak associations between CHD and stroke mortality and strong associations between CHD and stroke risk scores suggest that geographic variation in risk factors may not underlie geographic variations in stroke and CHID mortality. The relationship between risk factor scores and mortality was stronger for CHID than stroke. (C) 2009 Elsevier Inc. All rights reserved.

SO PROSTAGLANDINS LEUKOTRIENES AND ESSENTIAL FATTY ACIDS LA English DT Article; Proceedings Paper CT Workshop on DHA as a Required Nutrient CY JUN, 2008 CL Columbia, MD ID ALPHA-LINOLENIC ACID; POLYUNSATURATED FATTY-ACIDS; N-3 PUFA DEPRIVATION; DOCOSAHEXAENOIC ACID; ADULT-RATS; NUTRITIONAL DEPRIVATION; SIGNAL-TRANSDUCTION; PHOSPHOLIPASE A(2); PLASMA; CONVERSION AB Background: Docosahexaenoic acid (DHA) is required for normal brain function. The concentration of DHA in the brain depends on both diet and liver metabolism. Objective: To determine rat brain DHA concentration and consumption in relation to dietary n-3 (omega-3) polyunsaturated fatty acid (PUFA) content and liver secretion of DHA derived from circulating alpha-linolenic acid (alpha-LNA). Design: Following weaning, male rats were fed for 15 weeks either: (1) a diet with a high DHA and alpha-LNA content, (2) an n-3 PUFA "adequate" diet containing 4.6% alpha-LNA but no DHA, or (3) an n-3 PUFA "deficient" diet containing 0.2% alpha-LNA and no DHA. Brain DHA consumption rates were measured following intravenous infusion in unanesthetized rats of [1-C-14]DHA, whereas liver and brain DHA synthesis rates were measured by infusing [1-C-14]alpha-LNA. Results: Brain DHA concentrations equaled 17.6, 11.4 and 7.14 mu m/g in rats on diets 1, 2 and 3, respectively. With each diet, the rate of brain DHA synthesis from alpha-LNA was much less than the brain DHA consumption rate, whereas the liver synthesis-secretion rate was 5-10 fold higher. Higher elongase 2 and 5 and desaturase Delta 5 and Delta 6 activities in liver than in brain accounted for the higher liver DHA synthesis rates. Furthermore, these enzymes were transcriptionally upregulated in liver but not in brain of rats fed the deficient diet. Conclusions: While DHA is essential to normal brain function, this need might be covered by dietary alpha-LNA when liver metabolic conversion machinery is intact and the diet has a high alpha-LNA content.

Objective: Consider if statistical definitions for Daily Reference Intakes can be applied to n-3 HUFAs intakes during pregnancy for maternal and neurodevelopmental deficiencies. Design: Data were prospectively collected from women during pregnancy and children up to age 8 years participating in the Avon Longitudinal Study of Parents and Children (ALSPAC). Statistical analyses took social and lifestyle factors into account. Results: During pregnancy, n-3 HUFA intakes from seafood that putatively meet statistical definitions of an estimated average requirement ranged from 0.05 to 0.06 en% (111-139 mg/d/2000 Cal) for suboptimal fine motor control at 42 m and 0.065-0.08 en% (114-181 mg/d/2000 Cal) for suboptimal verbal IQ at age 8 years and 0.18-0.22 en% (389-486 mg/d/2000 Cal) for maternal depression at 32 weeks. Intakes of n-3 ranging from 0.2 to 0.41 en% (445-917 mg/d/2000 Cal) prevented both increased risk of maternal depression and adverse neurodevelopmental outcomes for children among 97.5% of the population. No upper limit for safety was found. Conclusion: During pregnancy, a n-3 HUFA intake of 0.40 en% (900 mg/d/2000 Cal) from seafood is likely to meet the nutritional requirements for 97.5% of the mothers and children of this population. These considerations do not constitute DRI's for docosahexaenoic acid and n-3 HUFAs, but may contribute to their formulation. Published by Elsevier Ltd.

Previously we showed that the quaking-induced conversion (QuIC) assay can detect sub-femtogram levels of PrPres in scrapie-infected hamster brain tissue and distinguish cerebral spinal fluid (CSF) samples from normal and scrapie-infected hamsters. We now report the adaptation of the QuIC reaction to prion diseases of medical and agricultural interest: human variant Creutzfeldt-Jakob disease (vCJD) and sheep scrapie. PrPres-positive and -negative brain homogenates from humans and sheep were discriminated within 1-2 days with a sensitivity of 10-100 fg PrPres. More importantly, in as little as 22 h we were able to distinguish CSF samples from scrapie-infected and uninfected sheep. These results suggest the presence of prions in CSF from scrapie-infected sheep. This new method enables the relatively rapid and sensitive detection of human CJD and sheep scrapie PrPres and may facilitate the development of practical preclinical diagnostic and high-throughput interference tests.

Some of these shared proteins or protein families may interact with diverse partners using the same interface regions; such multibinding proteins are the subject of our study. The main goal of our study is to attempt to decipher the mechanisms of specific molecular recognition of multiple diverse partners by promiscuous protein regions. To address this, we attempt to analyze the physicochemical properties of multibinding interfaces and highlight the major mechanisms of functional switches realized through multibinding. We find that only 5% of protein families in the structure database have multibinding interfaces, and multibinding interfaces do not show any higher sequence conservation compared with the background interface sites. We highlight several important functional mechanisms utilized by multibinding families. (a) Overlap between different functional pathways can be prevented by the switches involving nearby residues of the same interfacial region. (b) Interfaces can be reused in pathways where the substrate should be passed from one protein to another sequentially. (c) The same protein family can develop different specificities toward different binding partners reusing the same interface; and finally, (d) inhibitors can attach to substrate binding sites as substrate mimicry and thereby prevent substrate binding.

TI A novel peak detection approach with chemical noise removal using short-time FFT for prOTOF MS data SO PROTEOMICS LA English DT Article DE Adaptive short-time discrete Fourier transform; Complete linkage hierarchical clustering; Peak alignment; Peak detection; Undecimated wavelet transform ID MASS-SPECTROMETRY DATA; PROTEIN IDENTIFICATION; WAVELET TRANSFORM; QUANTIFICATION; ALGORITHM; SPECTRUM; MALDI AB Peak detection is a pivotal first step in biomarker discovery from MS data and can significantly influence the results of downstream data analysis steps. We developed a novel automatic peak detection method for prOTOF MS data, which does not require a priori knowledge of protein masses. Random noise is removed by an undecimated wavelet transform and chemical noise is attenuated by an adaptive short-time discrete Fourier transform. Isotopic peaks corresponding to a single protein are combined by extracting an envelope over them. Depending on the SIN, the desired peaks in each individual spectrum are detected and those with the highest intensity among their peak clusters are recorded. The common peaks among all the spectra are identified by choosing an appropriate cut-off threshold in the complete linkage hierarchical clustering. To remove the 1 Da shifting of the peaks, the peak corresponding to the same protein is determined as the detected peak with the largest number among its neighborhood. We validated this method using a data set of serial peptide and protein calibration standards. Compared with MoverZ program, our new method detects more peaks and significantly enhances SIN of the peak after the chemical noise removal. We then successfully applied this method to a data set from prOTOF MS spectra of albumin and albumin-bound proteins from serum samples of 59 patients with carotid artery disease compared to vascular disease-free patients to detect peaks with S/N >= 2. Our method is easily implemented and is highly effective to define peaks that will be used for disease classification or to highlight potential biomarkers.

TI Mental disorders as risk factors for later substance dependence: estimates of optimal prevention and treatment benefits SO PSYCHOLOGICAL MEDICINE LA English DT Article DE Mental disorders; prevention; substance dependence; treatment ID NATIONAL-COMORBIDITY-SURVEY; ALCOHOL-USE DISORDERS; CHILDHOOD PSYCHOPATHOLOGY INTERVENTIONS; REPLICATION NCS-R; AGE-OF-ONSET; ANXIETY DISORDERS; PSYCHIATRIC COMORBIDITY; EPIDEMIOLOGIC SURVEY; GENERAL-POPULATION; DRUG-ABUSE AB Background. Although mental disorders have been shown to predict subsequent substance disorders, it is not known whether substance disorders could be cost-effectively prevented by large-scale interventions aimed at prior mental disorders. Although experimental intervention is the only way to resolve this uncertainty, a logically prior question is whether the associations of mental disorders with subsequent substance disorders are strong enough to justify mounting such an intervention. We investigated this question in this study using simulations to estimate the number of substance disorders that might be prevented under several hypothetical intervention scenarios focused on mental disorders. Method. Data came from the National Comorbidity Survey Replication (NCS-R), a nationally representative US household survey that retrospectively assessed lifetime history and age of onset of DSM-IV mental and substance disorders. Survival analysis using retrospective age-of-onset reports was used to estimate associations of mental disorders with subsequent substance dependence. Simulations based on the models estimated effect sizes in several hypothetical intervention scenarios. Results. Although successful intervention aimed at mental disorders might prevent some proportion of substance dependence, the number of cases of mental disorder that would have to be treated to prevent a single case of substance dependence is estimated to be so high that this would not be a cost-effective way to prevent substance dependence (in the range 76-177 for anxiety-mood disorders and 40-47 for externalizing disorders). Conclusions. Treatment of prior mental disorders would not be a cost-effective way to prevent substance dependence. However, prevention of substance dependence might be considered an important secondary outcome of interventions for early-onset mental disorders. C1 [Glantz, M.

Neural activation was examined in striatal structures (nucleus accumbens, putamen, caudate) with a known role in facilitating response to salient reward-related cues. Adolescents with a history of behavioral inhibition, relative to noninhibited adolescents, showed increased activation in the nucleus accumbens when they believed their selection of an action would affect reward outcome. Neural responses did not differ between the two groups when participants made a prespecified response that they knew would result in reward or when they produced random motor responses that they knew would not be rewarded. These results link inhibited temperament and perturbed neural responses to reward-contingency cues. C1 [Bar-Haim, Yair] Tel Aviv Univ, Dept Psychol, IL-69978 Tel Aviv, Israel.

In addition to emotional disturbances, both mood and anxiety disorders are often characterized by disruptions in normal steep-wake cycles, a behavior that has not been well characterized in adversely reared non-human primates. Because polysomnographic measures are difficult to obtain in unrestrained monkeys we used 24-h actigraphy measures to assess probable steep-wake patterns in juvenile nursery- and mother-reared rhesus macaques (Macaca mulatto, N = 16) over several days in the home cage. In addition we assayed plasma cortisol in the morning, afternoon, and evening. Relative to mother-reared (MR) monkeys, actigraphic algorithms indicated that nursery-reared (NR) animals had shorter durations of nocturnal steep, earlier morning waking, and longer periods of steep during the active period, specifically in the mid morning. No shift in diurnal patterns of cortisol was observed, but NR animals displayed an overall elevation in cortisol. Finally a significant interaction was found between cortisol and actigraphic determination of steep efficiency in the two groups. A strong positive relationship (r(2) > 0.8) was found between mean cortisol levels and steep efficiency for the MR monkeys, but a significant negative relationship was found between these same variables for the NR monkeys, indicating a fundamentally different relationship between waking cortisol and actigraphy patterns in these two groups.

TI Acute tryptophan depletion evokes negative mood in healthy females who have previously experienced concurrent negative mood and tryptophan depletion SO PSYCHOPHARMACOLOGY LA English DT Article DE Serotonin; Mood; Females; Recurrence; Depression; Associative learning ID PREVIOUS DEPRESSIVE EPISODES; STRESSFUL LIFE EVENTS; SEROTONIN TRANSPORTER; MAJOR DEPRESSION; PLASMA TRYPTOPHAN; RAPID DEPLETION; MONOAMINE DEPLETION; SEX-DIFFERENCES; FAMILY-HISTORY; NORMAL MALES AB The majority of individuals who suffer an episode of depression go on to experience recurrences. We have proposed, based upon the observation that reducing serotonin via acute tryptophan depletion (ATD) is more likely to induce negative mood in recovered depressed individuals than never depressed individuals, that this may be because associations form between negative mood and reduced serotonin during an episode of depression (Robinson and Sahakian, Psychol Med 38:315-318, 2008b). Such associations would mean that subsequent reductions in serotonin are more likely to provoke depressed mood and hence trigger an episode of depression. In this study, we tested this hypothesis by manipulating the mood state of healthy females undergoing ATD (or balanced placebo) on two separate testing sessions. On the first session, subjects received either negative or neutral mood induction, while on the second session all subjects received neutral mood induction. Our findings demonstrate significant ATD-induced negative mood exclusively on the second visit of subjects who received both ATD and negative mood induction procedure on their first visit. These findings may be explained by the formation of an association between the negative mood and reduced serotonin states during the first visit. As such, these findings provide preliminary support for the associative hypothesis of recurrence in depression. Such associations might therefore explain the discrepancy between the effects of ATD in recovered- and never-depressed individuals and may, in turn, explain why an episode of depression increases the risk of subsequent episodes.

We sought to determine the relative roles of the two transmitters in the two major zones of the nucleus accumbens (NAS), the core and shell subregions. We assessed the effects of dopamine and glutamate receptor blockade in the core and shell on intravenous cocaine self-administration in rats. Trained animals were allowed to self-administer cocaine for an initial hour, and then D1-type or D2-type dopamine receptor blockers or NMDA-type or AMPA-type glutamate receptor blockers were infused by reverse microdialysis into one of the two regions for an additional 3 h of testing. The D1-type antagonist SCH23390 and the D2-type antagonist raclopride each increased cocaine intake whereas the AMPA-type antagonist CNQX decreased responding when infused into the core. SCH23390 increased cocaine intake less strongly when infused into the shell, while raclopride and CNQX were each ineffective when infused into the shell. The NMDA-antagonist CPP failed to affect cocaine self-administration when infused into either site. These findings implicate the core of NAS in the maintenance of established cocaine self-administration in trained animals, despite the fact that the reinforcement of responding in untrained animals appears to results from cocaine actions in the olfactory tubercle and medial shell and not the core of accumbens.

TI Up-regulation of 8-oxo-dGTPase Activity of MTH1 Protein in the Brain, Testes and Kidneys of Mice Exposed to Cs-137 gamma Radiation SO RADIATION RESEARCH LA English DT Article ID 5'-TRIPHOSPHATE PYROPHOSPHOHYDROLASE 8-OXO-DGTPASE; HUMAN MUTT HOMOLOG; SINGLE NUCLEOTIDE POLYMORPHISM; GENE-ENCODING 8-OXO-DGTPASE; HMTH1 MESSENGER-RNA; INDUCED DNA-DAMAGE; OXIDATIVE STRESS; NUCLEOSIDE TRIPHOSPHATASE; TRANSVERSION MUTATION; MUTAGENIC SUBSTRATE AB Mammalian MTH1 protein is an antimutagenic (2'-deoxy) ribonucleoside 5'-triphosphate pyrophosphohydrolase that prevents the incorporation of oxidatively modified nucleotides into nucleic acids. It decomposes most specifically the miscoding products of oxidative damage to purine nucleic acid precursors (e.g. 8-oxo-dGTP, 2-oxo-dATP, 2-oxo-ATP, 8-oxo-GTP) that may cause point mutations or transcription errors when incorporated into DNA and RNA, respectively. The increased expression of MTH1 mRNA and MTH1 protein was previously proposed as a molecular marker of oxidative stress. Therefore, we hypothesized that increased 8-oxo-dGTPase activity of MTH1 protein in mouse organs could serve as a dose-dependent marker of exposure to ionizing radiation, which is known to induce oxidative stress. To test our hypothesis, we measured 8-oxo-dGTPase activity in six organs of male BL6 mice after exposure to 0, 10, 25 and 50 cGy and 1 Gy of Cs-137 gamma radiation given as a single whole-body dose (1 Gy/min). The mice were killed 4, 8 and 24 h after irradiation. A statistically significant induction of 8-oxo-dGTPase was found in brains, testes and kidneys but not in lungs, hearts or livers. Brains, which demonstrated the highest (4.3-fold) increase of 8-oxo-dGTPase activity, were shown to express similar to 50% higher levels of MTH1 protein. However, due to the lack of a simple positive correlation between the dose and the observed 8-oxo-dGTPase activity in brain, testes and kidneys, we conclude that measurements of 8-oxo-dGTPase activity in these organs may serve as a rough indicator rather than a quantifiable marker of radiation-induced oxidative stress.

Biomarker Discovery in the Urine of Gamma-Irradiated Rats Using a Simplified Metabolomics Protocol of Gas Chromatography-Mass Spectrometry Combined with Random Forests Machine Learning Algorithm SO RADIATION RESEARCH LA English DT Article ID MICE; IDENTIFICATION; METABOLISM; PYRIMIDINES; EXPRESSION; INFECTION; EXPOSURE; PURINES; KIDNEY; CANCER AB Radiation metabolomics employing mass spectral technologies represents a plausible means of high-throughput minimally invasive radiation biodosimetry. A simplified metabolomics protocol is described that employs ubiquitous gas chromatography-mass spectrometry and open source software including random forests machine learning algorithm to uncover latent biomarkers of 3 Gy gamma radiation in rats. Urine was collected from six male Wistar rats and six sham-irradiated controls for 7 days, 4 prior to irradiation and 3 after irradiation. Water and food consumption, urine volume, body weight, and sodium, potassium, calcium, chloride, phosphate and urea excretion showed major effects from exposure to gamma radiation. The metabolomics protocol uncovered several urinary metabolites that were significantly up-regulated (glyoxylate, threonate, thymine, uracil, p-cresol) and down-regulated (citrate, 2-oxoglutarate, adipate, pimelate, suberate, azelaate) as a result of radiation exposure. Thymine and uracil were shown to derive largely from thymidine and 2'-deoxyuridine, which are known radiation biomarkers in the mouse. The radiation metabolomic phenotype in rats appeared to derive from oxidative stress and effects on kidney function. Gas chromatography-mass spectrometry is a promising platform on which to develop the field of radiation metabolomics further and to assist in the design of instrumentation for use in detecting biological consequences of environmental radiation release.

TI Protein carbonylation: avoiding pitfalls in the 2,4-dinitrophenylhydrazine assay SO REDOX REPORT LA English DT Article DE protein oxidation; carbonyl assay; nucleic acid; OxyBlot; bacteria; oxidative stress ID OXIDATIVELY MODIFIED PROTEINS; GLUTAMINE-SYNTHETASE; OXIDIZED PROTEINS; CELLS; ACIDS AB Protein carbonyl content is widely used as both a marker for oxidative stress and a measure of oxidative damage. Widely used methods for determination of protein carbonylation utilize the reaction of carbonyl groups with 2,4-dinitrophenylhydrazine (DNPH) to form protein-bound 2,4-dinitrophenylhydrazones. Hydrazones can be quantitated spectrophotometrically or, for greater sensitivity, detected immunochemically with anti-dinitrophenyl antibodies. Attention to methodology is important to avoid artifactual elevation in protein carbonyl measurements. We studied extracts of Escherichia coli to identify and eliminate such effects. Nucleic acid contamination caused serious artifactual increases in the protein carbonyl content determined by spectrophotometric techniques. Both in vitro synthesized DNA oligonucleotides and purified chromosomal DNA reacted strongly with 2,4-DNPH. Treatment of cell extracts with DNasee+RNase or with streptomycin sulfate to precipitate nucleic acids dramatically reduced the apparent carbonyl, while exposure to proteinase K did not. The commercial kit for immunochemical detection of protein carbonylation (OxyBlot (TM) from Chemicon/Millipore) recommends a high concentration of thiol in the homogenizing buffer. We found this recommendation leads to an artifactual doubling of the protein carbonyl, perhaps due to a thiol-stimulated Fenton reaction. Avoiding oxidizing conditions, removal of nucleic acids, and prompt assay of samples can prevent artifactual effects on protein carbonyl measurements.

Recently, a Multidimensional Prognostic Index (MPI) for 1-year mortality derived from a Comprehensive Geriatric Assessment (CGA) was developed and validated in hospitalized elderly patients. The aim of this study was to investigate the possible association of the APOE and ACE gene polymorphisms with the multidimensional impairment, as evaluated by the MPI, in older patients. These polymorphisms were assessed in 1894 geriatric inpatients divided into three groups according to their MPI values: MPI-1 low risk (n = 988), MPI-2 moderate risk (n = 671), and MPI-3 severe risk of mortality (n = 235). A slight deviation from Hardy-Weinberg equilibrium was observed for the APOE genotypes. With the increasing of the MPI grade, a significant increase in the frequencies of epsilon 4 allele and the ACE D/D genotype was observed. The APOE epsilon 4(+) and ACE D/D genotypes were associated with severe MPI grade (APOE epsilon 4(+), odds ration [OR] = 1.79, 95% confidence interval [CI] 1.20-2.67; ACE D/D, OR = 1.42, 95% CI 1.05-1.92). The combined APOE epsilon 4(+) and ACE D/D genetic status was associated with higher MPI grade (OR = 2.85, 95% CI 1.75-4.65), without interaction. No significant associations between APOE and ACE polymorphisms and 2-year mortality were found. APOE and ACE genes might predispose individuals to health and functional status deterioration in old age, and their effect is additive.

Subsequent primer extension terminates at the site of chemical modification, and these products are fractionated by high-resolution gel electrophoresis. When applying SHAPE to investigate structural features associated with the wild-type and analog-substituted polypurine tract (PPT)-containing RNA/DNA hybrids, their size (20-25 base pairs) rendered primer extension impractical. As an alternative method of detection, we reasoned that chemical modification could be combined with tandem mass spectrometry, relying on the mass increment of RNA fragments containing the NMIA adduct (M(r) = 133 Da). Using this approach, we demonstrate both specific modification of the HIV-1 PPT RNA primer and variations in its acylation pattern induced by replacing template nucleotides with a non-hydrogen-bonding thymine isostere. Our selective 2'-hydroxyl acylation analyzed by mass spectrometry strategy (SHAMS) should find utility when examining the structure of small RNA fragments or RNA/DNA hybrids where primer extension cannot be performed.

At 3 months, Fmod KO, Bgn KO and DKO displayed torn cruciate ligaments and EO in their quadriceps tendon, menisci and cruciate and patellar ligaments. The phenotype was the least severe in the Fmod KO, intermediate in the Bgn KO and the most severe in the DKO. This condition progressed with age in all three mouse strains and resulted in the development of large supernumerary sesmoid bones. To determine the role of exercise in the extent of EO, we subjected normal and DKO mice to a treadmill exercise 3 days a week for 4 weeks. In contrast to previous findings using more rigorous exercise regimes, the EO in moderately exercised DKO was decreased compared with unexercised DKO mice. Finally, DKO and Bgn KO mice tested using a rotarod showed a reduced ability to maintain their grip on a rotating cylinder compared with wild-type controls. In summary, we show (1) a detailed description of EO formed by Bgn, Fmod or combined depletion, (2) the role of exercise in modulating EO and (3) that Bgn and Fmod are critical in controlling motor function.

Clinical manifestations are often subtle or may be ascribed to other cancer complications, eg, treatment-related disorders or brain parenchymal metastases. CSF cytology has a high specificity (>95%), but its sensitivity is generally less than 50%. MRI sensitivity and specificity vary With the type of primary cancer, overall, MRI findings consistent with leptomeningeal disease are detected in fewer than 50% of NM patients. While most clinicians evaluate CSF cytology along with MRI and the clinical examination, underdiagnosis is a major problem, since many patients are both cytologically and radiographically negative. Failure to consider NM in the differential diagnosis magnifies the problem of underdiagnosis. CSF flow cytometry is particularly promising for evaluating NM from hematologic cancers, with a diagnostic sensitivity many fold greater than conventional cytology. Research has focused on identifying biochemical markers of tumor cells in the CSF. For example, molecules involved in CNS penetration (eg, matrix metalloproteinases and cathepsins), tumor cell tropism (eg, chemokines; CXCL8 and CCL18), and angiogenesis (eg, vascular endothelial growth factor) are elevated in the CSF of patients with NM. Evidence that some tumor types are more likely to infiltrate the CNS also has stimulated research into primary tumor markers predictive of CNS metastases. At present, there is no tumor marker or patient characteristic that reliably predicts the development of NM, and diagnosis still relies on suggestive signs and symptoms, positive CSF cytology, or a consistent MRI-all late manifestations of NM. Until techniques capable of detecting NM early are developed, increased awareness of the disease and standardized evaluation are likely to have the greatest impact on improving diagnosis and implementing earlier treatment.

Renal cell carcinoma is now known to be a polymorphic malignant neoplasm consisting of several histologic subtypes demonstrating different biological profiles. Clear cell renal carcinoma, the most common histologic subtype, is predominantly associated with mutations involving the von Hippel-Lindau gene and elaboration of vascular and somatic growth factors. Clear cell renal cell carcinoma is thus typically hypervascular at imaging. By contrast, papillary renal cell carcinoma, the second most common subtype, is frequently hypovascular. Current molecular data on the biology of renal neoplasms have shown important diagnostic, therapeutic, and prognostic implications, Comprehensive knowledge of molecular pathways of carcinogenesis of renal cancers has allowed design of rational treatment protocols and posttreatment surveillance algorithms, thereby permitting optimal patient management.

Objectives: Assessment of current and evolving tools for evaluating human spinal cord injury (SCI) outcomes for both clinical diagnosis and clinical research studies. Methods: a framework for the appraisal of evidence of metric properties was used to examine outcome tools or tests for accuracy, sensitivity, reliability and validity for human SCI. Results: Imaging, neurological, functional, autonomic, sexual health, bladder/bowel, pain and psychosocial tools were evaluated. Several specific tools for human SCI studies have or are being developed to allow the more accurate determination for a clinically meaningful benefit (improvement in functional outcome or quality of life) being achieved as a result of a therapeutic intervention. Conclusion: Significant progress has been made, but further validation studies are required to identify the most appropriate tools for specific targets in a human SCI study or clinical trial.

A modern method for testing this relative potency is to fit a nonlinear model of the dose-response curve, constrained such that the dose-response of the test is modeled with the same function as the reference except for a multiplicative parameter on the dose. This method works well as long as the nonlinear model fits the data. Although tests of this fit are mentioned in the literature, how relative potency should be measured when those tests fail has not been addressed. We study the use of the sandwich estimator of variance for this noninferiority potency problem when the model does not fit the data. We focus on the simple linear model. Using the sandwich variance, the inferences are asymptotically valid even if the model does not hold. We discuss interpretation of the results under the misspecified linear model, and show by simulation that the method performs well in some practical cases. Finally, we give advice for designing a study that uses these methods. C1 [Fay, Michael P.] NIAID, Biostat Res Branch, Bethesda, MD 20892 USA.

One allele of Olig2 locus was replaced by a green fluorescent protein (GFP) cassette with a targeting efficiency of 5.7%. Targeted clone R-Olig2 (like the other clones) retained pluripotency, typical hESC morphology, and a normal parental karyotype 46,XY. Most importantly, GFP expression recapitulated endogenous Olig2 expression when R-Olig2 was induced by sonic hedgehog and retinoic acid, and GFP-positive cells could be purified by fluorescence-activated cell sorting. Consistent with previous reports on rodents, early GFP-expressing cells appeared biased to a neuronal fate, whereas late GFP-expressing cells appeared biased to an oligodendrocytic fate. This was corroborated by myoblast coculture, transplantation into the rat spinal cords, and whole genome expression profiling. The present work reports an hESC reporter line generated by homologous recombination targeting a neural lineage-specific gene, which can be differentiated and sorted to obtain pure neural progenitor populations.

We hypothesized that plasma ADMA concentrations are positively related to common carotid artery intimal-media thickness (CCA-IMT) and to internal carotid (ICA)/bulb IMT. Methods-We investigated the cross-sectional relations of plasma ADMA with CCA-IMT and ICA/bulb IMT in 2958 Framingham Heart Study participants (mean age, 58 years; 55% women). Results-In unadjusted analyses, ADMA was positively related to both CCA-IMT (beta per SD increment, 0.012; P < 0.001) and ICA/bulb IMT (beta per SD increment, 0.059; P < 0.001). In multivariable analyses (adjusting for age, sex, systolic blood pressure, antihypertensive treatment, smoking status, diabetes, BMI, total-to-HDL cholesterol ratio, log C-reactive protein, and serum creatinine), plasma ADMA was not associated with CCA-IMT (P = 0.991), but remained significantly and positively related to ICA/bulb IMT (beta per SD increment, 0.0246; P = 0.002). Conclusions-In our large community-based sample, we observed that higher plasma ADMA concentrations were associated with greater ICA/bulb IMT, but not with CCA-IMT. These data are consistent with the notion that ADMA promotes subclinical atherosclerosis in a site-specific manner, with a greater proatherogenic influence at known vulnerable sites in the arterial tree.

When obtaining the maximum likelihood estimator (MLE) of theta in the presence of lambda requires intensive computation, the pseudo MLE of theta, based on a pseudo likelihood function, can be used. Gong and Samaniego (Ann. Stat. 9:861-869, 1981) proposed a pseudo MLE (PMLE) based on simple random samples. Ranked set sampling has been applied to the bivariate variables (X,Y) where measuring one of the variables is difficult or costly. In this paper, we obtain the pseudo MLE of the correlation coefficient from a bivariate normal distribution (X,Y) based on ranked set samples, assuming that Y is difficult or more expensive to measure and that the mean and variance of Y are the nuisance parameters. The PMLE is compared with three other estimators of the correlation coefficient. Simulations show that the PMLE is more (less) efficient than other estimators, depending on value of rho. Testing of soil contamination provides an example of the use of the methods. C1 [Zheng, Gang] NHLBI, Off Biostat Res, Bethesda, MD 20892 USA.

The process of leukocyte extravasation from the blood into the inflamed tissue requires a complex cascade of adhesive events between the leukocytes and the endothelium including leukocyte rolling, adhesion and trans-endothelial migration. Leukocyte-endothelial interactions are mediated by tightly regulated binding interactions between adhesion receptors on both cells. In this regard, leukocyte adhesion onto the endothelium is governed by leukocyte integrins and their endothelial counter-receptors of the immunoglobulin superfamily. The present review will focus on novel aspects with respect to the modulation of the leukocyte adhesion cascade.

The authors investigated the relationship between cTnI concentration in serum and histologic lesions in heart tissue from mice treated with isoproterenol (ISO). Cardiac TnI concentrations in serum increased in a dose-dependant manner and remained increased twenty-four to forty-eight hours after a single administration of isoproterenol. Increased cTnI concentration was of greater magnitude and longer duration than increased fatty acid binding protein 3 concentration, aspartate aminotransferase activity, and creatine kinase activity in serum. Isoproterenol-induced increases in cTnI concentrations were both greater and more sustained in BALB/c than in CD1 mice and correlated with incidence and severity of lesions observed in heart sections from both strains. In drug development studies in BALB/c mice with novel kinase inhibitors, cTnI concentration was a reliable stand-alone biomarker of cardiac injury and was used in combination with measurements of in vivo target inhibition to demonstrate an off-target contribution to cardiotoxicity. Additional attributes, including low cost and rapid turnaround time, made cTnI concentration in serum invaluable for detecting cardiotoxicity, exploring structure activity relationships, and prioritizing development of compounds with improved safety profiles early in drug discovery.

TI Points to Consider on the Statistical Analysis of Rodent Cancer Bioassay Data When Incorporating Historical Control Data SO TOXICOLOGIC PATHOLOGY LA English DT Article DE boxplot; IQR; lower quartile; median; range; upper quartile; historical control data ID INCREASED CARCINOGENICITY; CONTROL INFORMATION; TREND TESTS; PROPORTIONS; MORTALITY AB Researchers routinely use historical control data (HCD) when analyzing rodent carcinogenicity data obtained in a particular study. Although the concurrent control group is considered to be the most relevant group to compare with the dose groups, the HCD provides a broader perspective to assist in understanding the significance of the current study. The HCD is used to provide information about the incidences of spontaneous tumors and malignant systemic disorders such as lymphoma and leukemia. This article presents some possible ways of incorporating the HCD when analyzing data from a rodent cancer bioassay. Specifically, exploratory (informal) and formal statistical procedures for analyzing such data are reviewed. The boxplot is presented as an exploratory tool that describes the current data in the context of the distribution of the HCD. It will also identify potential outliers that would not be otherwise be flagged using standard methods such as the mean, standard deviation, and range. The various options for the statistical analysis of HCD presented here do not necessarily represent standard practice.

SO TOXICOLOGICAL SCIENCES LA English DT Editorial Material DE nanoparticles; risk assessment ID WALL CARBON NANOTUBES; PULMONARY TOXICITY; NANOTECHNOLOGY; NANOPARTICLES; NANOMATERIALS; SAFE AB Over the past 5 years we have seen an increase in the attention focused on the assessment of the potential health risk posed by nanoscale materials. The diversity of these materials with respect to size, composition, and surface properties, and the rapid pace of their development and commercialization, poses significant challenges to traditional toxicity testing paradigms. At the same time the potential use of new high throughput "predictive "toxicity" strategies, such as that envisioned in the recent NRC report "Toxicity Testing in the 21st Century," have emerged as possible solutions to deal with the issue of how to assess the safety of the thousands of chemicals to which humans are potentially exposed. In this forum article we discuss how in some respects, the emergence of diverse engineered nanomaterials offers a tailor-made test case for the application of a new paradigm for assessing human heath risks. However, although this approach may have merit in the study of some specific nanomaterials, this approach does not consider the complexity involved in utilizing in vitro cell culture toxicology methods to evaluate the potential hazard of the wide array of current and future engineered nanomaterials.

However, it features a low specificity and provides only limited mechanistic information required for risk assessment of positive findings. This is especially important in case of positive findings in the in vitro chromosome damage assays, because chromosome damage may be also induced secondarily to cell death. An increasing body of evidence indicates that toxicogenomic analysis of cellular stress responses provides an insight into mechanisms of action of genotoxicants. To evaluate the utility of such a toxicogenomic analysis we evaluated gene expression profiles of TK6 cells treated with four model genotoxic agents using a targeted high density real-time PCR approach in a multilaboratory project coordinated by the Health and Environmental Sciences Institute Committee on the Application of Genomics in Mechanism-based Risk Assessment. We show that this gene profiling technology produced reproducible data across laboratories allowing us to conclude that expression analysis of a relevant gene set is capable of distinguishing compounds that cause DNA adducts or double strand breaks from those that interfere with mitotic spindle function or that cause chromosome damage as a consequence of cytotoxicity. Furthermore, our data suggest that the gene expression profiles at early time points are most likely to provide information relevant to mechanisms of genotoxic damage and that larger gene expression arrays will likely provide richer information for differentiating molecular mechanisms of action of genotoxicants. Although more compounds need to be tested to identify a robust molecular signature, this study confirms the potential of toxicogenomic analysis for investigation of genotoxic mechanisms.

Reactive oxygen species (ROS) are often implicated in Cd toxicology. This minireview focused on direct evidence for the generation of free radicals in intact animals following acute Cd overload and discussed the association of ROS in chronic Cd toxicity and carcinogenesis. Cd-generated superoxide anion, hydrogen peroxide, and hydroxyl radicals in vivo have been detected by the electron spin resonance spectra, which are often accompanied by activation of redox sensitive transcription factors (e.g., NF-kappa B, AP-1 and Nrf2) and alteration of ROS-related gene expression. It is generally agreed upon that oxidative stress plays important roles in acute Cd poisoning. However, following long-term Cd exposure at environmentally-relevant low levels, direct evidence for oxidative stress is often obscure. Alterations in ROS-related gene expression during chronic exposures are also less significant compared to acute Cd poisoning. This is probably due to induced adaptation mechanisms (e.g., metallothionein and glutathione) following chronic Cd exposures, which in turn diminish Cd-induced oxidative stress. In chronic Cd-transformed cells, less ROS signals are detected with fluorescence probes. Acquired apoptotic tolerance renders damaged cells to proliferate with inherent oxidative DNA lesions, potentially leading to tumorigenesis. Thus, ROS are generated following acute Cd overload and play important roles in tissue damage. Adaptation to chronic Cd exposure reduces ROS production, but acquired Cd tolerance with aberrant gene expression plays important roles in chronic Cd toxicity and carcinogenesis.

MT plays minimal roles in the gastrointestinal absorption of Cd, but MT plays important roles in Cd retention in tissues and dramatically decreases biliary excretion of Cd. Cd-bound to MT is responsible for Cd accumulation in tissues and the long biological half-life of Cd in the body. Induction of MT protects against acute Cd-induced lethality, as well as acute toxicity to the liver and lung. Intracellular MT also plays important roles in ameliorating Cd toxicity following prolonged exposures, particularly chronic Cd-induced nephrotoxicity, osteotoxicity, and toxicity to the lung, liver, and immune system. There is an association between human and rodent Cd exposure and prostate cancers, especially in the portions where MT is poorly expressed. MT expression in Cd-induced tumors varies depending on the type and the stage of tumor development. For instance, high levels of MT are detected in Cd-induced sarcomas at the injection site, whereas the sarcoma metastases are devoid of MT. The use of MT-transgenic and MT-null mice has greatly helped define the role of MT in Cd toxicology, with the MT-null mice being hypersensitive and MT-transgenic mice resistant to Cd toxicity. Thus, MT is critical for protecting human health from Cd toxicity. There are large individual variations in MT expression, which might in turn predispose some people to Cd toxicity.

TI Expression of kidney injury molecule-1 (Kim-1) in relation to necrosis and apoptosis during the early stages of Cd-induced proximal tubule injury SO TOXICOLOGY AND APPLIED PHARMACOLOGY LA English DT Article DE Cadmium; Kim-1; Necrosis; Apoptosis; Proximal tubule ID CADMIUM-INDUCED HEPATOTOXICITY; RENAL INJURY; CELL-DEATH; TOXIC METALS; NEPHROTOXICITY; RATS; METALLOTHIONEIN; INTOXICATION; BIOMARKERS; GENTAMICIN AB Cadmium (Cd) is a nephrotoxic industrial and environmental pollutant that causes a generalized dysfunction of the proximal tubule. Kim-1 is a transmembrane glycoprotein that is normally not detectable in non-injured kidney, but is up-regulated and shed into the urine during the early stages of Cd-induced proximal tubule injury. The objective of the present study was to examine the relationship between the Cd-induced increase in Kim-1 expression and the onset of necrotic and apoptotic cell death in the proximal tubule. Adult male Sprague-Dawley rats were treated with 0.6 mg (5.36 mu mol) Cd/kg, subcutaneously, 5 days per week for up to 12 weeks. Urine samples were analyzed for levels of Kim-1 and the enzymatic markers of cell death, lactate dehydrogenase (LDH) and alpha-glutathione-S-transferase (alpha-GST). In addition, necrotic cells were specifically labeled by perfusing the kidneys in situ with ethidium homodimer using a procedure that has been recently developed and validated in the Prozialeck laboratory. Cryosections of the kidneys were also processed for the immunofluorescent visualization of Kim-1 and the identification of apoptotic cells by TUNEL labeling. Results showed that significant levels of Kim-1 began to appear in the urine after 6 weeks of Cd treatment, whereas the levels of total protein, alpha-GST and LDH were not increased until 8-12 weeks. Results of immunofluorescence labeling studies showed that after 6 weeks and 12 weeks, Kim-1 was expressed in the epithelial cells of the proximal tubule, but that there was no increase in the number of necrotic cells, and only a modest increase in the number of apoptotic cells at 12 weeks. These results indicate that the Cd-induced increase in Kim-1 expression occurs before the onset of necrosis and at a point where there is only a modest level of apoptosis in the proximal tubule.

These mice are characterized by defects in pigmentation, hearing loss and vestibular defects, suggesting that MCOLN3 might play a role in melanosome trafficking and hair cell maturation. Recent evidence has shown that MCOLN3 is a Ca(2+)-permeable channel and its activity is regulated by pH. Here we show that MCOLN3 primarily localizes to early and late endosomes in human epithelial cells. This distribution at the less acidic portions of the endocytic pathway is consistent with the reported inactivation of the channel by low pH. Furthermore, overexpression of MCOLN3 causes dramatic alterations in the endosomal pathway, including enlargement of Hrs-positive endosomes, delayed degradation of epidermal growth factor (EGF) and EGF receptor (EGFR) and defective autophagosome maturation, whereas depletion of endogenous MCOLN3 enhances EGFR degradation. Finally, we found that endosomal pH is higher in cells overexpressing MCOLN3 and propose a model in which Ca(2+) release from endosomes mediated by MCOLN3 might be important for efficient endosomal acidification. Therefore, MCOLN3 is a novel Ca(2+) channel that plays a crucial role in the regulation of cargo trafficking along the endosomal pathway.

The last common ancestor of modern eukaryotes is now known to have had at least moderately intron-dense genes and two complex spliceosomes. For other splicing-related phenomena the evolutionary history is less clear. We suggest that frequent mis-splicing is likely to be ancestral to eukaryotes, whereas trans-splicing and operon splicing are likely to be more recent. The origins of regulated splicing, alternative splicing and splicing of untranslated transcript regions are less certain. The data discussed underscore the significant genomic complexity of early eukaryotes, and should help to frame future questions about the origins of eukaryotic genome structure.

Recent studies have intriguingly suggested the existence of a functional ECS in the skin and implicated it in various biological processes (e.g. proliferation, growth, differentiation, apoptosis and cytokine, mediator or hormone production of various cell types of the skin and appendages, such as the hair follicle and sebaceous gland). It seems that the main physiological function of the cutaneous ECS is to constitutively control the proper and well-balanced proliferation, differentiation and survival, as well as immune competence and/or tolerance, of skin cells. The disruption of this delicate balance might facilitate the development of multiple pathological conditions and diseases of the skin (e.g. acne, seborrhea, allergic dermatitis, itch and pain, psoriasis, hair growth disorders, systemic sclerosis and cancer).

Such radiotracers must fulfill many criteria, among which an ability to enter brain adequately and reversibly without contamination by troublesome radio-metabolites is desirable for accurate measurement of the density of a target protein (e.g. neuroreceptor, transporter, enzyme or plaque). Candidate radiotracers can fail as a result of poor passive brain entry, rejection from brain by efflux transporters or undesirable metabolism. These issues are reviewed. Emerging PET radiotracers for measuring efflux transporter function and new strategies for ameliorating radiotracer metabolism are discussed. A growing understanding of the molecular features affecting the brain penetration, metabolism and efflux transporter sensitivity of prospective radiotracers should ultimately lead to their more rational and efficient design, and also to their greater efficacy.

Participants were 111 men and women with PAD (ankle-brachial index (ABI) <= 0.95) who completed baseline testing in the Study to Improve Leg Circulation (SILC). We evaluated FMD of the brachial artery at baseline and at 60 seconds following 4 minutes of suprasystolic blood pressure cuff inflation. Physical activity was measured continuously over 7 days using a vertical accelerometer (Caltrac) and a pedometer (Digiwalker). Adjusting for age, sex, race, ABI, cardiovascular risk factors and other potential confounders, higher levels of physical activity were associated with a greater percent change in brachial artery FMD at 60 seconds post cuff deflation for both Caltrac (1st tertile of activity +4.81% change; 2nd tertile +4.60% change; 3rd tertile +7.23% change; p-trend = 0.018) and the Digiwalker (1st tertile of activity +3.76% change; 2nd tertile +6.25% change; 3rd tertile +7.25% change; p-trend = 0.001). Similar findings were observed for absolute change in brachial artery FMD 60 seconds after cuff deflation. In conclusion, higher levels of physical activity during daily life are associated significantly and independently with better brachial artery FMD among individuals with PAD, even after adjusting for confounders.

Here we show that viral gene flow from Eurasia has led to the replacement of endemic avian influenza viruses in North America, likely through competition for susceptible hosts. This competition is characterized by changes in rates of nucleotide substitution and selection the discontinuous distribution of susceptible hosts may produce long periods of co-circulation of competing virus strains before lineage extinction occurs. These results also suggest that viral competition for host resources may be an important mechanism in disease emergence. (C) 2009 Elsevier Inc. All rights reserved.

A growing body of data indicates that these early and late steps in HIV-1 replication take place in specialized plasma membrane microdomains, and that many of the viral and cellular components required for entry, assembly, and budding are concentrated in these microdomains. In particular, a number of studies have shown that cholesterol- and sphingolipid-enriched microdomains known as lipid rafts play important roles in multiple steps in the virus replication cycle. In this review, we provide an overview of what is currently known about the involvement of lipids and membrane microdomains in HIV-1 replication. Published by Elsevier B.V.

Why EBV is associated with different malignancies in different geographic regions remains puzzling and may be related to EBV genotypic variability through specific disease and geographic associations. We review the literature on sequence variation in EBV genes, focusing on LMP-1, EBNA-1, and BZLF-1 and their distribution by geography and disease. Given the limitations of current studies, definitive conclusions regarding the link between EBV genotypes, disease and geography are not possible. We suggest that the true extent of EBV diversity is likely to be greater than is currently recognized. Additional studies conducted in carefully selected populations, that are sufficiently powered to provide robust estimates, and that utilize testing approaches that permit full characterization of viral diversity are needed to further our understanding of patterns of EBV genetic variation and their association with malignancies in different regions.

We have utilized the SIV/rhesus monkey model to evaluate whether samples more easily obtained than peripheral blood might be used for intensive monitoring of vaccine trial participants. Methods: We have evaluated viral loads in peripheral blood, saliva, feces, and urine of five rhesus monkeys during primary SIV(mac251) infection by quantitative real-time PCR. As an alternative to the direct monitoring of frozen samples, we have also developed a fully quantitative viral load assay utilizing dried blood spots. Results: Although all compartments were found to harbor viral RNA during primary infection, viral RNA could be detected in the peripheral compartments only when levels of plasma viremia exceed a threshold value of 10(4) RNA copies/ml. We found no direct correlation between viral burden in plasma and saliva, feces, or urine viral loads. Importantly, both dried saliva and whole blood spots can be used for viral detection. Quantitative whole blood or plasma spotting correlated well with viral burden in plasma during both the acute and set point phase of infection. Conclusion: Dried blood spots are amenable to rapid quantitative viral load testing. Whole blood spotting has a significant logistical benefit as it requires low blood volumes and no blood processing. Saliva or dried saliva spots or both are potential candidates for acute phase diagnostic screening. These studies indicate the feasibility of intensive monitoring of HIV-1 vaccine trial participants for virus acquisition in resource-limited settings.

TI Incident HIV and herpes simplex virus type 2 infection among men in Rakai, Uganda SO AIDS LA English DT Article DE herpes simplex virus type 2; HIV; male circumcision; risk factors; Uganda ID HUMAN-IMMUNODEFICIENCY-VIRUS; GENITAL HERPES; MALE CIRCUMCISION; FACTORY-WORKERS; ACQUISITION; WOMEN; RISK; ASSOCIATION; PREVENTION; PREVALENCE AB Objective: Herpes simplex virus type 2 (HSV-2) infection is associated with an increased risk for acquiring HIV, but little is known about the temporal sequence of these infections. Design: Six thousand three hundred ninety-six men were evaluated for serologic HSV-2 and HIV infections and behaviors during a male circumcision trial in Rakai, Uganda. Methods: HIV and HSV-2 status were determined using enzyme-linked immunosorbent assays and confirmed by HIV-1 and HSV-2 western blots. A Poisson multivariable model was used to estimate adjusted incidence rate ratios of HIV acquisition associated with HSV-2 and other covariates. Results: HIV incidence was 1.09/100 person-years and acquisition was associated with incident HSV-2 infection [adjusted incidence rate ratio (adjIRR) 5.28, 95% confidence interval (CI) 2.79-9.98], chronic HSV-2 infection (adjIRR 2.78, 95% Cl 1.64-5.68), genital ulcer disease, urethral discharge, genital washing after intercourse, being unmarried, and being uncircumcised. Sixteen men acquired both HIV and HSV-2 during the trial: four acquired HIV first, three acquired HSV-2 first, and [line acquired both infections in the same follow-up interval. Conclusion: The findings suggest that unsafe sex places men at risk of both HIV and HSV-2 infections, and it is unclear whether HSV-2 acquisition is a cofactor for HIV infection or a marker of correlated sexual exposures. This reinforces the need for promotion of safe sex as the primary method of prevention of both viruses. (C) 2009 Wolters Kluwer Health | Lippincott Williams & Wilkins C1 [Tobian, Aaron A.

TI Arachidonic Acid Stimulates Cell Adhesion through a Novel p38 MAPK-RhoA Signaling Pathway That Involves Heat Shock Protein 27 SO JOURNAL OF BIOLOGICAL CHEMISTRY LA English DT Article ID GTP-BINDING PROTEIN; NUCLEOTIDE EXCHANGE FACTOR; HETEROTRIMERIC G-PROTEINS; KINASE-DEPENDENT PATHWAY; BREAST-CARCINOMA CELLS; FACTOR-KAPPA-B; ACTIN CYTOSKELETON; PROSTATE-CANCER; CYCLOOXYGENASE-2 EXPRESSION; ACTIVATING PROTEIN AB Rho GTPases are critical components of cellular signal transduction pathways. Both hyperactivity and overexpression of these proteins have been observed in human cancers and have been implicated as important factors in metastasis. We previously showed that dietary n-6 fatty acids increase cancer cell adhesion to extracellular matrix proteins, such as type IV collagen. Here we report that in MDA-MB-435 human melanoma cells, arachidonic acid activates RhoA, and inhibition of RhoA signaling with either C3 exoenzyme or dominant negative Rho blocked arachidonic acid-induced cell adhesion. Inhibition of the Rho kinase (ROCK) with either small molecule inhibitors or ROCK II-specific small interfering RNA (siRNA) blocked the fatty acid-induced adhesion. However, unlike other systems, inhibition of ROCK did not block the activation of p38 mitogen-activated protein kinase (MAPK); instead, Rho activation depended on p38 MAPK activity and the presence of heat shock protein 27 (HSP27), which is phosphorylated downstream of p38 after arachidonic acid treatment. HSP27 associated with p115RhoGEF in fatty acid-treated cells, and this association was blocked when p38 was inhibited. Furthermore, siRNA knockdown of HSP27 blocked the fatty acid-stimulated Rho activity. Expression of dominant negative p115-RhoGEF or p115RhoGEF-specific siRNA inhibited both RhoA activation and adhesion on type IV collagen, whereas a constitutively active p115RhoGEF restored the arachidonic acid stimulation in cells in which the p38 MAPK had been inhibited. These data suggest that n-6 dietary fatty acids stimulate a set of interactions that regulates cell adhesion through RhoA and ROCK II via a p38 MAPK-dependent association of HSP27 and p115RhoGEF.

In the present study, we investigated the phosphoinositide dependence of Orai1 channel activation in the PM and of STIM1 movements from the tubular to PM-adjacent endoplasmic reticulum regions during Ca2+ store depletion. Phosphatidylinositol 4,5-bisphosphate ( PtdIns( 4,5)P-2) levels were changed either with agonist stimulation or by chemically induced recruitment of a phosphoinositide 5-phosphatase domain to the PM, whereas PtdIns4P levels were decreased by inhibition or down-regulation of phosphatidylinositol 4-kinases (PI4Ks). Agonist-induced phospholipase C activation and PI4K inhibition, but not isolated PtdIns(4,5)P-2 depletion, substantially reduced endogenous or STIM1/Orai1-mediated SOCE without preventing STIM1 movements toward the PM upon Ca2+ store depletion. Patch clamp analysis of cells overexpressing STIM1 and Orai1 proteins confirmed that phospholipase C activation or PI4K inhibition greatly reduced I-CRAC currents. These results suggest an inositide requirement of Orai1 activation but not STIM1 movements and indicate that PtdIns4P rather than PtdIns(4,5)P-2 is a likely determinant of Orai1 channel activity.

Here, site-directed spin labeling was used to generate models for the solution and membrane-bound structures of a soluble fragment of syt1 containing its two C2 domains, C2A and C2B. In solution, distance restraints between the two C2 domains of syt1 were measured using double electron-electron resonance and used in a simulated annealing routine to generate models for the structure of the tandem C2A-C2B fragment. The data indicate that the two C2 domains are flexibly linked and do not interact with each other in solution, with or without Ca(2+). However, the favored orientation is one where the Ca(2+)-binding loops are oriented in opposite directions. A similar approach was taken for membrane-associated C2A-C2B, combining both distances and bilayer depth restraints with simulated annealing. The restraints can only be satisfied if the Ca(2+) and membrane-binding surfaces of the domains are oriented in opposite directions so that C2A and C2B are docked to opposing bilayers. The result suggests that syt1 functions to bridge across the vesicle and plasma membrane surfaces in a Ca(2+)-dependent manner. (C) 2009 Elsevier Ltd. All rights reserved.

Stoichiometric and molecular mass analysis established that this signal-end complex (SEC) contains two protomers each of RAG1 and RAG2. Visualization of the SEC by negative-staining electron microscopy revealed an anchor-shaped particle with approximate two-fold symmetry. Consistent with a parallel arrangement of DNA and protein subunits, the N termini of RAG1 and RAG2 are positioned at opposing ends of the complex, and the DNA chains beyond the RSS nonamer emerge from the same face of the complex, near the RAG1 N termini. These first images of the V(D)J recombinase in its post-cleavage state provide a framework for modeling RAG domains and their interactions with DNA.

These measurements provide a sensitive test of theories proposed in the past decade of escape driven by random thermal noise from a periodically modulated potential.

Here, we show that chronic stress biases decision-making strategies, affecting the ability of stressed animals to perform actions on the basis of their consequences. Using two different operant tasks, we revealed that, in making choices, rats subjected to chronic stress became insensitive to changes in outcome value and resistant to changes in action-outcome contingency. Furthermore, chronic stress caused opposing structural changes in the associative and sensorimotor corticostriatal circuits underlying these different behavioral strategies, with atrophy of medial prefrontal cortex and the associative striatum and hypertrophy of the sensorimotor striatum. These data suggest that the relative advantage of circuits coursing through sensorimotor striatum observed after chronic stress leads to a bias in behavioral strategies toward habit.

We have developed an optical tweezers assay to follow individual Pol II complexes as they transcribe nucleosomal DNA. Our results indicate that the nucleosome behaves as a fluctuating barrier that locally increases pause density, slows pause recovery, and reduces the apparent pause-free velocity of Pol II. The polymerase, rather than actively separating DNA from histones, functions instead as a ratchet that rectifies nucleosomal fluctuations. We also obtained direct evidence that transcription through a nucleosome involves transfer of the core histones behind the transcribing polymerase via a transient DNA loop. The interplay between polymerase dynamics and nucleosome fluctuations provides a physical basis for the regulation of eukaryotic transcription.

However, some of the genes identified in these screens have no effect on the human malaria parasite Plasmodium falciparum; raising the question of whether different mosquito effector genes mediate anti-parasitic responses to different Plasmodium species. Results: Four new An. gambiae (G3) genes were identified that, when silenced, have a different effect on P. berghei (Anka 2.34) and P. falciparum (3D7) infections. Orthologs of these genes, as well as LRIM1 and CTL4, were also silenced in An. stephensi (Nijmegen Sda500) females infected with P. yoelii (17XNL). For five of the six genes tested, silencing had the same effect on infection in the P. falciparum-An. gambiae and P. yoelii-An. stephensi parasite-vector combinations. Although silencing LRIM1 or CTL4 has no effect in An. stephensi females infected with P. yoelii, when An. gambiae is infected with the same parasite, silencing these genes has a dramatic effect. In An. gambiae (G3), TEP1, LRIM1 or LRIM2 silencing reverts lysis and melanization of P. yoelii, while CTL4 silencing enhances melanization. Conclusion: There is a broad spectrum of compatibility, the extent to which the mosquito immune system limits infection, between different Plasmodium strains and particular mosquito strains that is mediated by TEP1/LRIM1 activation. The interactions between highly compatible animal models of malaria, such as P. yoelii (17XNL)-An. stephensi (Nijmegen Sda500), is more similar to that of P. falciparum (3D7)-An. gambiae (G3).

Understanding and improving the cellular efficacy of dendrimer-drug conjugates, can lead to significant in vivo benefits. This study explores efficacy of anionic polyamidoamine (PAMAM-COOH) dendrimer-N-acetyl cysteine (NAC) conjugates for applications in neuroinflammation. The anti-oxidative and anti-inflammatory effects of PAMAM-(COOH)(46)-(NAC)(18) conjugate is evaluated on microglial cells in vitro. Cell entry and localization of PAMAM-(COOH)(62)-(FITC)(2) conjugate in BV-2 microglial cells were assessed using flow cytometry and confocal microscopy. ELISA assays were used to evaluate markers of oxidative stress (ROS, NO) and inflammation (TNF-alpha) after stimulation of microglial cells with lipopolysaccharides (LPS), following treatment with increasing doses of free N-acetyl-L-cysteine (NAC) or PAMAM-(COOH)(46)-(NAC)(18) conjugate containing an equivalent molar concentration of NAC. Flow cytometry and confocal microscopy demonstrated the PAMAM-(COOH)(62)-(FITC)(2) conjugate entered BV-2 cells rapidly with significant increase in fluorescence within 15 min and localized mostly in the cytoplasm. PAMAM-(COOH)(46)-(NAC)(18) conjugate was non-toxic, and significantly reduced ROS, NO and TNF-alpha release by activated microglial cells after 24 h and 72 h stimulation of LPS following 3 h pre-treatment when compared to the same concentration of free NAC (P<0.05 or P<0.01). Anionic PAMAM dendrimer-NAC conjugate was synthesized with a glutathione sensitive linker for intracellular release. The non-toxic conjugate is a more effective anti-oxidant and anti-inflammatory agent when compared to free NAC in vitro. The conjugate showed significant efficacy even at the lowest dose (0.5 mM NAC), where the activity was comparable or better than that of free drug at 8 mM (16x higher dosage). The improved efficacy of the conjugate, when combined with the intrinsic neuroinflammation-targeting ability of the PAMAM dendrimers, may provide new opportunities for in vivo applications.

It has been developed over the last three decades with a primary focus on molecules of biological interest, including proteins, peptides, lipids, nucleic acids, carbohydrates, and small molecule ligands, as they occur in solution, crystals, and membrane environments. For the study of such systems. the program provides a large suite of computational tools that include numerous conformational and path sampling methods, free energy estimators, molecular minimization, dynamics, and analysis techniques, and model-building capabilities. The CHARMM program is applicable to problems involving a much broader class of many-particle systems. Calculations with CHARMM can be performed using a number of different energy functions and models, from mixed quantum mechanical-molecular mechanical force fields, to all-atom classical potential energy functions with explicit solvent and various boundary conditions, to implicit solvent and membrane models. The program has been ported to numerous platforms in both serial and parallel architectures. This article provides an overview of the program as it exists today with an emphasis on developments since the publication of the original CHARMM article in 1983. (C) 2009 Wiley Periodicals, Inc.

TI Crystal structures of HIV-1 nonnucleoside reverse transcriptase inhibitors: N-benzyl-4-methyl-benzimidazoles SO JOURNAL OF MOLECULAR STRUCTURE LA English DT Article DE AIDS; HIV-1; Reverse transcriptase inhibitor; Drug design; Crystal structure ID RESISTANCE MUTATIONS; BIOLOGICAL-ACTIVITY; WILD-TYPE; COMPLEX; DESIGN; POTENT; RESOLUTION; MUTANT; 1H,3H-THIAZOLO<3,4-A>BENZIMIDAZOLES; REPLICATION AB HIV-1 nonnucleoside reverse transcriptase inhibitors are potentially specific and effective drugs in AIDS therapy. The presence of two aromatic systems with an angled orientation in the molecule of the inhibitor is crucial for interactions with HIV-1 RT. The inhibitor drives like a wedge into the cluster of aromatic residues of RT HIV-1 and restrains the enzyme in a conformation that blocks the chemical step of nucleotide incorporation. Structural studies provide useful information for designing new, more active inhibitors. The crystal structures of four NNRTIs are presented here. The investigated compounds are derivatives of N-benzyl-4-methyl-benzimidazole with various aliphatic and aromatic substituents at carbon 2 positions and a 2,6-dihalogeno-substituted N-benzyl moiety. Structural data reported here show that the conformation of the investigated compounds is relatively rigid. Such feature is important for the nonnucleoside inhibitor binding to HIV-1 reverse transcriptase. (C) 2009 Published by Elsevier B.V.

This methods paper describes a protocol, modeled on protocols typically used to culture neural stem/precursor cells, that generates a predictable positive control of an intense scarring reaction. Six independent cell culture variables (growth media, seeding density, bFGF addition day, serum concentration in treatment media, treatment day, and duration of culture) were varied systematically and the resulting scars were quantified. The following conditions were found to give the highest level of scarring: Neurobasal medium supplemented with 1327, 10% fetal bovine serum at treatment, 10 ng/ml b-FGF addition at seeding and at treatment, treatment at least 6 days after seeding and scar growth of at least 5 days. Seeding density did not affect scarring as long as at least 500,000 cells were seeded per well, but appropriate media, bFGF, and serum were essential for significant scar formation-insights that help validate the in vitro-based approach to understanding glial scarring. With the control protocol developed in this study producing a strong, reproducible glial scarring positive control with every dissection, this culture model is suitable for the in vitro study of the mechanisms behind glial scarring and neuroelectrode failure.

TI Transgenic mice expressing a cameleon fluorescent Ca2+ indicator in astrocytes and Schwann cells allow study of glial cell Ca2+ signals in situ and in vivo SO JOURNAL OF NEUROSCIENCE METHODS LA English DT Article DE YC 3.60 cameleon; Astrocytes; Schwann cells; Transgenic mice ID GENETICALLY ENCODED INDICATORS; SYNAPTIC-TRANSMISSION; NEURONAL-ACTIVITY; TEMPORAL EXPRESSION; NEURAL ACTIVITY; NERVOUS-SYSTEM; CALCIUM WAVES; TROPONIN-C; GLUTAMATE; RECEPTORS AB Glial cell Ca2+ signals play a key role in glial-neuronal and glial-glial network communication. Numerous studies have thus far utilized cell-permeant and injected Ca2+ indicator dyes to investigate glial Ca2+ signals in vitro and in situ. Genetically encoded fluorescent Ca2+ indicators have emerged as novel probes for investigating cellular Ca2+ signals. We have expressed one such indicator protein, the YC 3.60 cameleon, under the control of the S100 beta promoter and directed its expression predominantly in astrocytes and Schwann cells. Expression of YC 3.60 extended into the entire cellular cytoplasmic compartment and the fine terminal processes of protoplasmic astrocytes and Schwann cell Cajal bands. In the brain, all the cells known to express S100 beta in the adult or during development, expressed YC 3.60. While expression was most extensive in astrocytes, other glial cell types that express S100 beta, such as NG2 and CNP-positive oligodendrocyte progenitor cells (OP cells), microglia, and some of the large motor neurons in the brain stem, also contained YC 3.60 fluorescence. Using a variety of known in situ and in vivo assays, we found that stimuli known to elicit Ca2+ signals in astrocytes caused substantial and rapid Ca2+ signals in the YC 3.60-expressing astrocytes. In addition, forepaw stimulation while imaging astrocytes through a cranial window in the somatosensory cortex in live mice, revealed robust evoked and spontaneous Ca2+ signals. These results, for the first time, show that genetically encoded reporter is capable of recording activity-dependent Ca2+ signals in the astrocyte processes, and networks. Published by Elsevier B.V.

In addition, the multiplication of transgenes included in mouse models of human disease underlines the importance of correct controls and the fact that investigators need an accurate and rapid genotyping of the littermates generated. In this study, we demonstrate a powerful alternative for genotyping using presenilin-1 mutant knock-in (PS1M146KI) mice as an example. Mutations in the presenilin-1 (PSI) gene are causally linked to many cases of early-onset inherited Alzheimer's disease (AD). PS1M146VKI mice that express the PS1M146V targeted allele at normal physiological levels and triple-transgenic model (3xTg-AD) derived from homozygous PS1M146VKI mice were generated to study the pathogenesis of AD. Genotyping PS1M146VKI line requires many steps and thus a large quantity of DNA. In PS1M146VKI mice, only three nucleotides are modified in the gene. Here we show that this small mutated DNA sequence can affect its secondary structure resulting in altered mobility that can be easily detected on a polyacrylamide gel, by the single-strand conformation polymorphism (SSCP) technique. Our results demonstrate that SSCP is a simple, accurate, repeatable and efficient method for the routine genotyping of this current AD model. This method could be easily applied to other transgenic mice. (C) 2009 Elsevier B.V. All rights reserved.

The Questionnaire for Impulsive-compulsive Disorders in Parkinson's Disease (QUIP) has 3 sections: Section 1 assesses four ICDs (involving gambling, sexual, buying, and eating behaviors), Section 2 other compulsive behaviors (punding, hobbyism, and walkabout), and Section 3 Compulsive medication use. For validation, a convenience sample of 157 PD patients at 4 movement disorders centers first completed the QUIP, and then was administered a diagnostic interview by a trained rater blinded to the QUIP results. A shortened instrument (QUIP-S) was then explored. The discriminant validity of the QUIP was high for each disorder or behavior (receiver operating characteristic area under the curve [ROC AUC]: gambling = 0.95, sexual behavior = 0.97, buying = 0.87, eating = 0.88, punding = 0.78, hobbyism = 0.93, walkabout = 0.79). On post hoc analysis, the QUIP-S ICD section had similar properties (ROC AUC: gambling = 0.95, sexual behavior = 0.96, buying = 0.87, eating = 0.88). When disorders/behaviors were combined, the sensitivity of the QUIP and QUIP-S to detect an individual with any disorder was 96 and 94%, respectively. Scores on the QUIP appear to be valid as a self-assessment screening instrument for a range of ICDs and other compulsive behaviors that occur in PD, and a shortened version may perform as well as the full version. A positive screen should be followed by a comprehensive, clinical interview to determine the range and severity of symptoms, as well as need for clinical management.

Two stimuli, one red and the other blue, appeared sequentially on a video screen-in either order. Later, both stimuli reappeared, and to receive a reward the monkeys had to choose the stimulus that had lasted longer during its initial presentation. Some neurons encoded stimulus duration, but a larger number of cells represented their relative duration, which was encoded in three ways: whether the first or second stimulus had lasted longer; whether the red or blue stimulus had lasted longer; or, less commonly, as the difference between the two durations. As the monkeys' choice approached, the signal encoding which stimulus (red or blue) had lasted longer increased as the order-based signal dissipated. By representing stimulus durations and relative durations-both bound to Stimulus features and event order-the frontal cortex could contribute to both temporal perception and episodic memory.

SO NEW ENGLAND JOURNAL OF MEDICINE LA English DT Article ID GASTRIC BYPASS-SURGERY; MORTALITY RISK SCORE; MULTIVARIATE-ANALYSIS; MORBID-OBESITY; OUTCOMES AB Background: To improve decision making in the treatment of extreme obesity, the risks of bariatric surgical procedures require further characterization. Methods: We performed a prospective, multicenter, observational study of 30-day outcomes in consecutive patients undergoing bariatric surgical procedures at 10 clinical sites in the United States from 2005 through 2007. A composite end point of 30-day major adverse outcomes (including death; venous thromboembolism; percutaneous, endoscopic, or operative reintervention; and failure to be discharged from the hospital) was evaluated among patients undergoing first-time bariatric surgery. Results: There were 4776 patients who had a first-time bariatric procedure (mean age, 44.5 years; 21.1% men; 10.9% nonwhite; median body-mass index [the weight in kilograms divided by the square of the height in meters], 46.5). More than half had at least two coexisting conditions. A Roux-en-Y gastric bypass was performed in 3412 patients (with 87.2% of the procedures performed laparoscopically), and laparoscopic adjustable gastric banding was performed in 1198 patients; 166 patients underwent other procedures and were not included in the analysis. The 30-day rate of death among patients who underwent a Roux-en-Y gastric bypass or laparoscopic adjustable gastric banding was 0.3%; a total of 4.3% of patients had at least one major adverse outcome. A history of deep-vein thrombosis or pulmonary embolus, a diagnosis of obstructive sleep apnea, and impaired functional status were each independently associated with an increased risk of the composite end point. Extreme values of body-mass index were significantly associated with an increased risk of the composite end point, whereas age, sex, race, ethnic group, and other coexisting conditions were not. Conclusions: The overall risk of death and other adverse outcomes after bariatric surgery was low and varied considerably according to patient characteristics. In helping patients make appropriate choices, short-term safety should be considered in conjunction with both the long-term effects of bariatric surgery and the risks associated with being extremely obese.

Both vaccines elicited CD4(+) T-cell responses, but with significant differences in the phenotype of the Gag-specific cells: the native Gag induced CD4(+) responses with a phenotype of central memory-like T cells (CD28(+) CD45RA(-)), whereas the LAMP/Gag chimera induced CD4(+) responses with effector memory phenotype (CD28(-) CD45RA(-)). Antigen-specific T cells producing both IFN-gamma and TNF alpha were found in the animals receiving the native Gag, whereas the LAMP/Gag chimera induced humoral responses faster. These results demonstrate that modification of intracellular Gag trafficking results in the induction of distinct immune responses. Combinations of DNA vectors encoding both forms of antigen may be more potent in eliciting anti-HIV-1 immunity. Published by Elsevier Ltd.

TI Genetic polymorphisms of the GNRH1 and GNRHR genes and risk of breast cancer in the National Cancer Institute Breast and Prostate Cancer Cohort Consortium (BPC3) SO BMC CANCER LA English DT Article ID BASE-LINE CHARACTERISTICS; MULTIETHNIC COHORT; ASSOCIATION; NUTRITION; WOMEN; POPULATIONS; ESTROGENS; ANDROGENS; SAMPLE; HEALTH AB Background: Gonadotropin releasing hormone (GNRH1) triggers the release of follicle stimulating hormone and luteinizing hormone from the pituitary. Genetic variants in the gene encoding GNRH1 or its receptor may influence breast cancer risk by modulating production of ovarian steroid hormones. We studied the association between breast cancer risk and polymorphisms in genes that code for GNRH1 and its receptor (GNRHR) in the large National Cancer Institute Breast and Prostate Cancer Cohort Consortium (NCI-BPC3). Methods: We sequenced exons of GNRH1 and GNRHR in 95 invasive breast cancer cases. Resulting single nucleotide polymorphisms ( SNPs) were genotyped and used to identify haplotype-tagging SNPs (htSNPS) in a panel of 349 healthy women. The htSNPs were genotyped in 5,603 invasive breast cancer cases and 7,480 controls from the Cancer Prevention Study-II (CPS-II), European Prospective Investigation on Cancer and Nutrition ( EPIC), Multiethnic Cohort (MEC), Nurses' Health Study ( NHS), and Women's Health Study (WHS). Circulating levels of sex steroids ( androstenedione, estradiol, estrone and testosterone) were also measured in 4713 study subjects. Results: Breast cancer risk was not associated with any polymorphism or haplotype in the GNRH1 and GNRHR genes, nor were there any statistically significant interactions with known breast cancer risk factors. Polymorphisms in these two genes were not strongly associated with circulating hormone levels. Conclusion: Common variants of the GNRH1 and GNRHR genes are not associated with risk of invasive breast cancer in Caucasians.

Because of their extreme polarity, neurons require specialized mechanisms to regulate mitochondrial transport and retention in axons. Our previous studies using syntaphilin (snph) knock-out mice provided evidence that SNPH targets to axonal mitochondria and controls their mobility through its static interaction with microtubules (MTs). However, the mechanisms regulating SNPH-mediated mitochondrial docking remain elusive. Here, we report an unexpected role for dynein light chain LC8. Using proteomic biochemical and cell biological assays combined with time-lapse imaging in live snph wild-type and mutant neurons, we reveal that LC8 regulates axonal mitochondrial mobility by binding to SNPH, thus enhancing the SNPH-MT docking interaction. Using mutagenesis assays, we mapped a seven-residue LC8-binding motif. Through this specific interaction, SNPH recruits LC8 to axonal mitochondria; such colocalization is abolished when neurons express SNPH mutants lacking the LC8-binding motif. Transient LC8 expression reduces mitochondrial mobility in snph (+/+) but not (-/-) neurons, suggesting that the observed effect of LC8 depends on the SNPH-mediated docking mechanism. In contrast, deleting the LC8-binding motif impairs the ability of SNPH to immobilize axonal mitochondria. Furthermore, circular dichroism spectrum analysis shows that LC8 stabilizes an alpha-helical coiled-coil within the MT-binding domain of SNPH against thermal unfolding. Thus, our study provides new mechanistic insights into controlling mitochondrial mobility through a dynamic interaction between the mitochondrial docking receptor and axonal cytoskeleton.

Behavioral rhythms abound at frequencies at or below 10 Hz. Neuronal rhythms cover a very wide frequency range, and the phase of neuronal low-frequency rhythms often rhythmically modulates the strength of higher-frequency rhythms, particularly of gamma-band synchronization (GBS). Here, we study stimulus-induced GBS in awake monkey areas V1 and V4 in relation to a specific form of spontaneous behavior, namely microsaccades (MSs), small fixational eye movements. We found that MSs occur rhythmically at a frequency of similar to 3.3 Hz. The rhythmic MSs were predicted by the phase of the 3.3 Hz rhythm in V1 and V4 local field potentials. In turn, the MSs modulated both visually induced GBS and the speed of visually triggered behavioral responses. Fast/slow responses were preceded by a specific temporal pattern of MSs. These MS patterns induced perturbations in GBS that in turn explained variability in behavioral response speed. We hypothesize that the 3.3 Hz rhythm structures the sampling and exploration of the environment through building and breaking neuronal ensembles synchronized in the gamma-frequency band to process sensory stimuli.

Significant changes can also occur in the amide one-bond (IN)-I-15-H-1 Scalar coupling constants for glutamine binding protein(GlnBP) due to ligand binding. Like chemical shift perturbations, large changes (>1 Hz) are seen near the site of glutamine binding, though perturbations also occur distant to the site. The coupling constant perturbations correlate with significant structural changes,especially changes in backbone hydrogen bonding. Thus, amide scalar coupling perturbation can serve as an adjunct to chemical shift perturbation, providing additional information on both short-range and longer-range, allosteric structural changes.

We reconstituted the mitochondrial targeting and insertion of TSPO into the OMM to analyze the signals and mechanisms required for this process. Initial Studies indicated the formation of a mitochondrial 66 kDa. complex through Blue Native-PAGE analysis. The formation of this complex was found to be dependent on the presence of ATP and the cytosolic chaperone Hsp90. Through mutational analysis we identified two areas necessary for TSPO targeting, import, and function: amino acids 103-108 (Schellman motif), which provide the necessary structural orientation for import, and the cholesterol-binding C-terminus required for insertion. Although the translocase of the outer mitochondrial membrane (TOM) complex proteins Tom22 and Tom40 were present in the OMM, the TOM complex did not interact with TSPO. In search of proteins involved in TSPO import, we analyzed complexes known to interact with TSPO by mass spectrometry. Formation of the 66 kDa complex Was found to be dependent on an identified protein, Metaxin 1, for formation and TSPO import. The level of import of TSPO into steroidogenic cell mitochondria was increased following treatment of the cells with cAMP. These findings suggest that the initial targeting of TSPO to mitochondria is dependent upon the presence of cytosolic chaperones interacting with the import receptor Tom70. The C-terminus plays an important role in targeting TSPO to mitochondria, whereas its import into the OMM is dependent upon the presence of the Schellman motif. Final integration of TSPO into the OMM occurs via its interaction with Metaxin 1. Import of TSPO into steroidogenic cell mitochondria is regulated by cAMP.

Although HIV-1 and Ty3 PPT sequences share no sequence similarity beyond the fact that both include runs of purine ribonucleotides, it has been suggested that these PPTs are processed by their cognate reverse transcriptases (RTs) through a common molecular mechanism. Here, we have used the aminoglycoside neomycin B (NB) to examine which structural features of the Ty3 PPT contribute to specific recognition and processing by its cognate RT. Using high-resolution NMR, direct infusion FTICR mass spectrometry, and isothermal titration calorimetry, we show that NB binds preferentially and selectively adjacent to the Ty3 3' PPT-U3 cleavage junction and in an upstream 5' region where the thumb subdomain of Ty3 RT putatively grips the substrate. Regions highlighted by NB oil the Ty3 PPT are similar to those previously identified oil the HIV-1 PPT sequence that are implicated as contact points for substrate binding by its RT. Our findings thus Support the notion that common structural features of lentiviral and LTR-retrotransposon PPTs facilitate the interaction with their cognate RT.

Design Population based cohort study. Setting Guanacaste, Costa Rica. Participants 2282 sexually active women actively followed after enrolment. Main outcome measures Primary end points: three year and five year cumulative incidence of histologically confirmed cervical intraepithelial neoplasia grade II+ (n=70). Cervical specimens collected at each visit tested for more than 40 HPV genotypes. HPV 16, 18, 26, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, 68, 73, and 82 were considered the primary carcinogenic genotypes. Results Women who tested positive for a carcinogenic HPV at enrolment and after about one year (9-21 months) (positive/positive) had a three year cumulative incidence of cervical intraepithelial neoplasia grade II+ of 17.0% (95% confidence interval 12.1% to 22.0%). Those who tested negative/positive (3.4%, 0.1% to 6.8%), positive/negative (1.2%,-0.2% to 2.5%), and negative/negative (0.5%, 0.1% to 0.9%) were at a significantly lower risk. There was little difference in the cumulative incidence of cervical intraepithelial neoplasia grade II+ between testing positive twice for any carcinogenic HPV genotype (same genotype or different genotypes) v testing positive twice for the same carcinogenic genotype (17.0% v 21.3%, respectively). Short term persistence of HPV 16 strongly predicted cervical intraepithelial neoplasia grade II+, with a three year cumulative incidence of 40.8% (26.4% to 55.1%). Similar patterns were observed for the five year cumulative incidence of grade II+ and for three year and five year cumulative incidence of grade III+. Conclusions Short term persistence of a prevalently detected carcinogenic HPV infection, especially HPV 16, strongly predicts a subsequent diagnosis of cervical intraepithelial neoplasia II+ over the next few years.

This method employs a homonuclear dipolar recoupling sequence that creates an average dipole-dipole coupling Hamiltonian under MAS with full zero-quantum symmetry, including both secular and flip-flop terms. Flip-flop terms are then attenuated by inserting rotor-synchronized periods of chemical shift evolution between recoupling blocks, leaving an effective Hamiltonian that contains only secular terms to a good approximation. Couplings between specific pairs of nuclear spins can then be selected with frequency-selective pi pulses. We demonstrate this technique, which we call zero-quantum shift evolution assisted homonuclear recoupling, in a series of one-dimensional and two-dimensional (13)C NMR experiments at 17.6 T and 40.00 kHz MAS frequency on uniformly (13)C-labeled L-threonine powder and on the helix-forming peptide MB(i+4)EK, synthesized with a pair of uniformly (13)C-labeled L-alanine residues. Experimental demonstrations include measurements of distances between (13)C sites that are separated by three bonds, placing quantitative constraints on both sidechain and backbone torsion angles in polypeptides.

TI Energetics of glutamate receptor ligand binding domain dimer assembly are modulated by allosteric ions SO PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA LA English DT Article DE allosteric modulation; analytical ultracentrifugation; desensitization; ion channels; thermodynamics ID CRYSTAL-STRUCTURES; KAINATE RECEPTORS; K+ CHANNEL; D-SERINE; DESENSITIZATION; MECHANISMS; AMPA; SUBUNIT; SELECTIVITY; CATIONS AB The activity of many ligand-gated ion channels and cell surface receptors is modulated by small molecules and ions, but an understanding of the underlying molecular mechanisms is scarce. For kainate, but not AMPA subtype glutamate receptors, the binding of Na(+) and Cl(-) ions to discrete, electrostatically coupled sites in the extracellular ligand binding domain (LBD) dimer assembly regulates the rate of entry into the desensitized state, which occurs when the dimer interface ruptures and the channel closes. Studies on glutamate receptors have defined the LBD dimer assembly as a key functional unit that controls activation and desensitization. Here we use analytical ultracentrifugation to probe the energetic effects of allosteric ions on kainate receptor dimer stability in solution, using a GluR6 mutant that desensitizes slowly. Our results show that sodium and chloride ions modulate kainate receptor dimer affinity as much as 50-fold, and that removal of either Cl(-) or Na(+) disrupts the dimer. The applicability of a similar allosteric mechanism for modulation of delta2 glutamate receptors by Ca(2+) was also tested. Our results indicate that ions can contribute substantial free energy to active state stabilization in both these receptors, and provide quantitative measurements of the energetic consequences of allosteric ion binding to a ligand-gated ion channel.

TI Capillary morphogenesis protein-2 is the major receptor mediating lethality of anthrax toxin in vivo SO PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA LA English DT Article DE edema toxin; lethal toxin; tumor endothelium marker-8 ID INFANTILE SYSTEMIC HYALINOSIS; BACILLUS-ANTHRACIS; MONOCLONAL-ANTIBODY; CELLULAR RECEPTOR; TUMOR ENDOTHELIUM; KINASE-KINASE; BINDING; INTERNALIZATION; MUTATIONS; IDENTIFICATION AB Anthrax toxin, a major virulence factor of Bacillus anthracis, gains entry into target cells by binding to either of 2 von Willebrand factor A domain-containing proteins, tumor endothelium marker-8 (TEM8) and capillary morphogenesis protein-2 (CMG2). The wide tissue expression of TEM8 and CMG2 suggest that both receptors could play a role in anthrax pathogenesis. To explore the roles of TEM8 and CMG2 in normal physiology, as well as in anthrax pathogenesis, we generated TEM8- and CMG2-null mice and TEM8/CMG2 double-null mice by deleting TEM8 and CMG2 transmembrane domains. TEM8 and CMG2 were found to be dispensable for mouse development and life, but both are essential in female reproduction in mice. We found that the lethality of anthrax toxin for mice is mostly mediated by CMG2 and that TEM8 plays only a minor role. This is likely because anthrax toxin has approximately 11-fold higher affinity for CMG2 than for TEM8. Finally, the CMG2-null mice are also shown to be highly resistant to B. anthracis spore infection, attesting to the importance of both anthrax toxin and CMG2 in anthrax infections.

TI Small-molecule agonists for the thyrotropin receptor stimulate thyroid function in human thyrocytes and mice SO PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA LA English DT Article DE 7TMR; G protein-coupled receptor; low-molecular-weight ligands; radioiodide uptake; TSH receptor ID LUTEINIZING-HORMONE RECEPTOR; PROTEIN-COUPLED RECEPTOR; RECOMBINANT HUMAN TSH; CRYSTAL-STRUCTURE; FSH RECEPTOR; WEIGHT AGONIST; HYPERTHYROIDISM; IDENTIFICATION; ANTAGONIST; ACTIVATION AB Seven-transmembrane-spanning receptors (7TMRs) are prominent drug targets. However, small-molecule ligands for 7-transmembrane-spanning receptors for which the natural ligands are large, heterodimeric glycoprotein hormones, like thyroid-stimulating hormone (TSH; thyrotropin), have only recently been reported, and none are approved for human use. We have used quantitative high-throughput screening to identify a small-molecule TSH receptor (TSHR) agonist that was modified to produce a second agonist with increased potency. We show that these agonists are highly selective for human TSHR versus other glycoprotein hormone receptors and interact with the receptor's serpentine domain. A binding pocket within the transmembrane domain was defined by docking into a TSHR homology model and was supported by site-directed mutagenesis. In primary cultures of human thyrocytes, both TSH and the agonists increase mRNA levels for thyroglobulin, thyroperoxidase, sodium iodide symporter, and deiodinase type 2, and deiodinase type 2 enzyme activity. Moreover, oral administration of the agonist stimulated thyroid function in mice, resulting in increased serum thyroxine and thyroidal radioiodide uptake. Thus, we discovered a small molecule that activates human TSHR in vitro, is orally active in mice, and could be a lead for development of drugs to use in place of recombinant human TSH in patients with thyroid cancer.

TI GABA(A) receptor membrane trafficking regulates spine maturity SO PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA LA English DT Article DE endocytosis; inhibition; phosphorylation ID PHOSPHO-DEPENDENT BINDING; AP2 COMPLEX; PHOSPHORYLATION; ENDOCYTOSIS; INHIBITION; MODULATION; CURRENTS; SUBUNIT; NEURONS; PSD-95 AB GABAA receptors (GABAARs), the principal sites of synaptic inhibition in the brain, are dynamic entities on the neuronal cell surface, but the role their membrane trafficking plays in shaping neuronal activity remains obscure. Here, weexamined this by using mutant receptor beta 3 subunits (beta 3S408/9A), which have reduced binding to the clathrin adaptor protein-2, a critical regulator of GABAAR endocytosis. Neurons expressing beta 3S408/9A subunits exhibited increases in the number and size of inhibitory synapses, together with enhanced inhibitory synaptic transmission due to reduced GABAAR endocytosis. Furthermore, neurons expressing beta 3S408/9A subunits had deficits in the number of mature spines and reduced accumulation of postsynaptic density protein-95 at excitatory synapses. This deficit in spine maturity was reversed by pharmacological blockade of GABAARs. Therefore, regulating the efficacy of synaptic inhibition by modulating GABAAR membrane trafficking may play a critical role in regulating spine maturity with significant implications for synaptic plasticity together with behavior.

TI Gliomas induce and exploit microglial MT1-MMP expression for tumor expansion SO PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA LA English DT Article DE brain tumor; invasion; metalloprotease; toll-like receptor ID TOLL-LIKE RECEPTOR-4; GLIOBLASTOMA CELLS; UP-REGULATION; BRAIN-TUMORS; IN-VITRO; INVASIVENESS; ACTIVATION; GENE; METALLOPROTEASE-2; INHIBITION AB Diffuse infiltration of glioma cells into normal brain tissue is considered to be a main reason for the unfavorable outcomes of patients with malignant gliomas. Invasion of glioma cells into the brain parenchyma is facilitated by metalloprotease- mediated degradation of the extracellular matrix. Metalloproteases are released as inactive pro-forms and get activated upon cleavage by membrane bound metalloproteases. Here, we show that membrane type 1 metalloprotease (MT1-MMP) is up-regulated in glioma-associated microglia, but not in the glioma cells. Overexpression of MT1-MMP is even lethal for glioma cells. Glioma-released factors trigger the expression and activity of MT1-MMP via microglial toll-like receptors and the p38 MAPK pathway, as deletion of the toll-like receptor adapter protein MyD88 or p38 inhibition prevented MT1-MMP expression and activity in cultured microglial cells. Microglial MT1-MMP in turn activates glioma-derived pro-MMP-2 and promotes glioma expansion, as shown in an ex vivo model using MT1-MMP-deficient brain tissue and a microglia depletion paradigm. Finally, MyD88 deficiency or microglia depletion largely attenuated glioma expansion in 2 independent in vivo models. C1 [Markovic, D.

TI Ionizing Radiation-Induced Oxidative Stress Alters miRNA Expression SO PLOS ONE LA English DT Article ID CELL-CYCLE PROGRESSION; MICRORNAOME DEREGULATION; TRANSCRIPTION FACTOR; KAPPA-B; RESISTANCE; SIGNATURE AB Background: MicroRNAs (miRNAs) are small, highly conserved, non-coding RNA that alter protein expression and regulate multiple intracellular processes, including those involved in the response to cellular stress. Alterations in miRNA expression may occur following exposure to several stress-inducing anticancer agents including ionizing radiation, etoposide, and hydrogen peroxide (H(2)O(2)). Methodology/Principal Findings: Normal human fibroblasts were exposed to radiation, H(2)O(2), or etoposide at doses determined by clonogenic cell survival curves. Total RNA was extracted and miRNA expression was determined by microarray. Time course and radiation dose responses were determined using RT-PCR for individual miRNA species. Changes in miRNA expression were observed for 17 miRNA species following exposure to radiation, 23 after H(2)O(2) treatment, and 45 after etoposide treatment. Substantial overlap between the miRNA expression changes between agents was observed suggesting a signature miRNA response to cell stress. Changes in the expression of selected miRNA species varied in response to radiation dose and time. Finally, production of reactive oxygen species (ROS) increased with increasing doses of radiation and pre-treatment with the thiol antioxidant cysteine decreased both ROS production and the miRNA response to radiation. Conclusions: These results demonstrate a common miRNA expression signature in response to exogenous genotoxic agents including radiation, H(2)O(2), and etoposide. Additionally, pre-treatment with cysteine prevented radiation-induced alterations in miRNA expression which suggests that miRNAs are responsive to oxidative stress. Taken together, these results imply that miRNAs play a role in cellular defense against exogenous stress and are involved in the generalized cellular response to genotoxic oxidative stress.

Recent data suggest that intracellular trafficking is of central importance in the production of A beta. Here we use a neuronal cell line to examine two structurally similar clathrin assembly proteins, AP180 and CALM. We show that RNA interference-mediated knockdown of AP180 reduces the generation of A beta 1-40 and AP1-42, whereas CALM knockdown has no effect on A beta generation. Thus AP180 is among the traffic controllers that oversee and regulate amyloid precursor protein processing pathways. Our results also suggest that AP180 and CALM, while similar in their domain structures and biochemical properties, are in fact dedicated to separate trafficking pathways in neurons..

CA NISC Comparative Sequencing Progra TI Distinct retroelement classes define evolutionary breakpoints demarcating sites of evolutionary novelty SO BMC GENOMICS LA English DT Article ID DISTANTLY RELATED MARSUPIALS; DOUBLE-STRAND BREAKS; CHROMOSOME EVOLUTION; KARYOTYPE RELATIONSHIPS; MAMMALIAN EVOLUTION; HUMAN GENOME; MOUSE; REARRANGEMENTS; CENTROMERE; SEQUENCES AB Background: Large-scale genome rearrangements brought about by chromosome breaks underlie numerous inherited diseases, initiate or promote many cancers and are also associated with karyotype diversification during species evolution. Recent research has shown that these breakpoints are nonrandomly distributed throughout the mammalian genome and many, termed "evolutionary breakpoints" (EB), are specific genomic locations that are "reused" during karyotypic evolution. When the phylogenetic trajectory of orthologous chromosome segments is considered, many of these EB are coincident with ancient centromere activity as well as new centromere formation. While EB have been characterized as repeat-rich regions, it has not been determined whether specific sequences have been retained during evolution that would indicate previous centromere activity or a propensity for new centromere formation. Likewise, the conservation of specific sequence motifs or classes at EBs among divergent mammalian taxa has not been determined. Results: To define conserved sequence features of EBs associated with centromere evolution, we performed comparative sequence analysis of more than 4.8 Mb within the tammar wallaby, Macropus eugenii, derived from centromeric regions (CEN), euchromatic regions (EU), and an evolutionary breakpoint (EB) that has undergone convergent breakpoint reuse and past centromere activity in marsupials. We found a dramatic enrichment for long interspersed nucleotide elements (LINE1s) and endogenous retroviruses (ERVs) and a depletion of short interspersed nucleotide elements (SINEs) shared between CEN and EBs. We analyzed the orthologous human EB (14q32.33), known to be associated with translocations in many cancers including multiple myelomas and plasma cell leukemias, and found a conserved distribution of similar repetitive elements. Conclusion: Our data indicate that EBs tracked within the class Mammalia harbor sequence features retained since the divergence of marsupials and eutherians that may have predisposed these genomic regions to large-scale chromosomal instability.

TI A Negative Feedback Control of Transforming Growth Factor-beta Signaling by Glycogen Synthase Kinase 3-mediated Smad3 Linker Phosphorylation at Ser-204 SO JOURNAL OF BIOLOGICAL CHEMISTRY LA English DT Article ID TGF-BETA; UBIQUITIN LIGASE; TRANSCRIPTIONAL ACTIVATION; CRYSTAL-STRUCTURE; BMP; DEGRADATION; PATHWAYS; DOMAIN; PROTEIN; IDENTIFICATION AB Through the action of its membrane-bound type I receptor, transforming growth factor-beta (TGF-beta) elicits a wide range of cellular responses that regulate cell proliferation, differentiation, and apoptosis. Many of these signaling responses are mediated by Smad proteins. As such, controlling Smad activity is crucial for proper signaling by TGF-beta and its related factors. Here, we show that TGF-beta induces phosphorylation at three sites in the Smad3 linker region in addition to the two C-terminal residues, and glycogen synthase kinase 3 is responsible for phosphorylation at one of these sites, namely Ser-204. Alanine substitution at Ser-204 and/or the neighboring Ser-208, the priming site for glycogen synthase kinase 3 in vivo activity, strengthened the affinity of Smad3 to CREB-binding protein, suggesting that linker phosphorylation may be part of a negative feedback loop that modulates Smad3 transcriptional activity. Thus, our findings reveal a novel aspect of the Smad3 signaling mechanism that controls the final amplitude of cellular responses to TGF-beta.

TI Glycopeptide-preferring Polypeptide GalNAc Transferase 10 (ppGalNAc T10), Involved in Mucin-type O-Glycosylation, Has a Unique GalNAc-O-Ser/Thr-binding Site in Its Catalytic Domain Not Found in ppGalNAc T1 or T2 SO JOURNAL OF BIOLOGICAL CHEMISTRY LA English DT Article ID ACETYL-D-GALACTOSAMINE; N-ACETYLGALACTOSAMINYLTRANSFERASE FAMILY; NEIGHBORING RESIDUE GLYCOSYLATION; PEPTIDE ACCEPTOR PREFERENCES; UDP-GALNAC; TANDEM REPEAT; FUNCTIONAL-CHARACTERIZATION; DROSOPHILA-MELANOGASTER; LINKED GLYCOSYLATION; STAUDINGER LIGATION AB Mucin-type O-glycosylation is initiated by a large family of UDP-GalNAc:polypeptide alpha-N-acetylgalactosaminyltransferases (ppGalNAc Ts) that transfer GalNAc from UDP-GalNAc to the Ser and Thr residues of polypeptide acceptors. Some members of the family prefer previously glycosylated peptides (ppGalNAc T7 and T10), whereas others are inhibited by neighboring glycosylation (ppGalNAc T1 and T2). Characterizing their peptide and glycopeptide substrate specificity is critical for understanding the biological role and significance of each isoform. Utilizing a series of random peptide and glycopeptide substrates, we have obtained the peptide and glycopeptide specificities of ppGalNAc T10 for comparison with ppGalNAc T1 and T2. For the glycopeptide substrates, ppGalNAc T10 exhibited a single large preference for Ser/Thr-O-GalNAc at the +1 (C-terminal) position relative to the Ser or Thr acceptor site. ppGalNAc T1 and T2 revealed no significant enhancements suggesting Ser/Thr-O-GalNAc was inhibitory at most positions for these isoforms. Against random peptide substrates, ppGalNAc T10 revealed no significant hydrophobic or hydrophilic residue enhancements, in contrast to what has been reported previously for ppGalNAc T1 and T2. Our results reveal that these transferases have unique peptide and glycopeptide preferences demonstrating their substrate diversity and their likely roles ranging from initiating transferases to filling-in transferases.

Binding of alpha S to membrane phospholipids is implicated in its functional role in synaptic regulation, but also impacts fibril formation associated with Parkinson's disease. We describe here a solution NMR study in which alpha S is added to small unilamellar vesicles of a composition mimicking synaptic vesicles; the results provide evidence for multiple distinct phospholipid-binding modes of US. Exchange between the free state and the lipid-bound alpha S state, and between different bound states is slow on the NMR timescale, being in the range of 1-10 s(-1). Partitioning of the binding modes is dependent on lipid/alpha S stoichiometry, and tight binding with slow-exchange kinetics is observed at stoichiometries as low as 2:1. In all lipid-bound states, a segment of residues starting at the N-terminus of alpha S adopts an alpha-helical conformation, while succeeding residues retain the characteristics of a random coil. The 40 C-terminal residues remain dynamically disordered, even at high-lipid concentrations, but can also bind to lipids to an extent that appears to be determined by the fraction of cis X-Pro peptide bonds in this region. While lipid-bound alpha S exhibits dynamic properties that preclude its direct observation by NMR, its exchange with the NMR-visible free form allows for its indirect characterization. Rapid amide-amide nuclear Overhauser enhancement buildup points to a large et-helical conformation, and a distinct increase in fluorescence anisotropy attributed to Tyr39 indicates an ordered environment for this "dark state." Titration of alpha S with increasing amounts of lipids suggests that the binding mode under high-lipid conditions remains qualitatively similar to that in the low-lipid case. The NMR data appear incompatible with the commonly assumed model where alpha S lies in an alpha-helical conformation on the membrane surface and instead suggest that considerable remodeling of the vesicles is induced by alpha S.

In our previous study, we showed that MDMA exposure inhibits the activity of the acetaldehyde (ACH) metabolizing enzyme, aldehyde dehydrogenase2 (ALDH2). Based on this finding, we hypothesized that the co-administration of MDMA and ethanol would reduce the metabolism of ACH and result in increased accumulation of ACH. Rats were treated with MDMA or vehicle and then administered a single dose of ethanol. Liver ALDH2 activity decreased by 35% in the MDMA-treated rats compared to control rats. The peak concentration and the area under the concentration versus time curve of plasma ACH were 31% and 59% higher, respectively, in the MDMA-ethanol group compared to the ethanol-only group. In addition, the MDMA-ethanol group had 80% higher plasma transaminase levels than the ethanol-only group, indicating greater hepatocellular damage. Our results not only support a drug interaction between MDMA and ethanol but a novel underlying mechanism for the interaction. (C) 2009 Elsevier Ireland Ltd. All rights reserved.

Using population-based data from Sweden, we identified 4458 MGUS patients, 17 505 population-based controls, and first-degree relatives of patients (n = 14 621) and controls (n = 58 387) with the aim to assess risk of MGUS and lymphoproliferative malignancies among first-degree relatives of MGUS patients. Compared with relatives of controls, relatives of MGUS patients had increased risk of MGUS (relative risk [RR] = 2.8; 1.4-5.6), multiple myeloma (MM; RR = 2.9; 1.9-4.3), lymphoplasmacytic lymphoma/Waldenstrom macroglobulinemia (LPL/WM; RR = 4.0; 1.5-11), and chronic lymphocytic leukemia (CLL; RR = 2.0; 1.2-2.3). Relatives of patients with IgG/IgA MGUS had a 4.0-fold (1.7-9.2), 2.9-fold (1.7-4.9), and 20-fold (2.3-170) elevated risk of developing MGUS, MM, and LPL/WM, respectively. Relatives of IgM MGUS patients had 5.0-fold (1.1-23) increased CLL risk and nonsignificant excess MM and LPL/WM risks. The results were very similar when we assessed risk by type of first-degree relative, age at MGUS (above/below 65 years), or sex. Risk of non-Hodgkin lymphoma or Hodgkin lymphoma was not increased among MGUS relatives. Among first-degree relatives of a nationwide MGUS cohort, we found elevated risks of MGUS, MM, LPL/WM, and CLL, supporting a role for germline susceptibility genes, shared environmental influences, or an interaction between both.

In contrast to FL carrying the t(14; 18), their t(14; 18)-negative counterparts are less well studied about their immunohistochemical, genetic, molecular, and clinical features. Within a previously published series of 184 FLs grades 1 to 3A with available gene expression data, we identified 17 FLs lacking the t(14; 18). Comparative genomic hybridization and high-resolution single nucleotide polymorphism (SNP) array profiling showed that gains/amplifications of the BCL2 gene locus in 18q were restricted to the t(14; 18)-positive FL subgroup. A comparison of gene expression profiles showed an enrichment of germinal center B cell-associated signatures in t(14; 18)-positive FL, whereas activated B cell-like, NF kappa B, proliferation, and bystander cell signatures were enriched in t(14; 18)-negative FL. These findings were confirmed by immunohistochemistry in an independent validation series of 84 FLs, in which 32% of t(14; 18)-negative FLs showed weak or absent CD10 expression and 91% an increased Ki67 proliferation rate. Although overall survival did not differ between FL with and without t(14; 18), our findings suggest distinct molecular features of t(14; 18)-negative FL.

The effects of 1 and 2 on the structure and permeability of human erythrocytes and rat liver mitochondria were compared. Compound 1 induced dose-dependent erythrocyte hemolysis and increased mitochondrial permeability, with concomitant changes in membrane structure as determined by ESR and fluorescence anisotropy methods. Immobilization of 1 on N-polyvinylpyrrolidone (compound 2) increased its water solubility and reduced the intensity of its effects oil erythrocyte membrane integrity and mitochondrial permeability, which correlated with a decrease in the membranes structural changes induced by the compound. Although the same concentrations of free and N-polyvinylpyrrolidone bound 1 were used, far less (14)C-labeled 1 was incorporated into the membranes from complex than free 1. The increase in water solubility and the reduction of membrane-active properties of 1 after immobilization oil N-polyvinylpyrrolidone could explain our previous observation of the decreased toxicity of 1.

TI Magnesium-Induced Lipid Bilayer Microdomain Reorganizations: Implications for Membrane Fusion SO JOURNAL OF PHYSICAL CHEMISTRY B LA English DT Article ID PHOSPHATIDYLSERINE-PHOSPHATIDYLCHOLINE VESICLES; LATERAL PHASE SEPARATIONS; DYNAMIC LIGHT-SCATTERING; CALCIUM-INDUCED FUSION; INFRARED-SPECTROSCOPY; PHOSPHOLIPID-BILAYERS; DOMAIN FORMATION; MODEL MEMBRANES; CELL-MEMBRANES; STALK MODEL AB Interactions between dipalmitoylphosphatidylcholine (DPPC) and dipalmitoylphosphatidylserine (DPPS), combined both as binary lipid bilayer assemblies and separately, under the influence of divalent Mg(2+), a membrane bilayer fusogenic agent, are reported. Infrared vibrational spectroscopic analyses of the lipid acyl chain methylene symmetric stretching modes indicate that aggregates of the two phospholipid components exist as domains heterogeneously distributed throughout the binary bilayer system. In the presence of Mg(2+) DPPS maintains an ordered orthorhombic subcell gel phase structure through the phase transition temperature, while the DPPC component is only minimally perturbed with respect to the gel to liquid crystalline phase change. The addition of Mg(2+) induces a reorganization of the lipid domains in which the gel phase acyl chain planes rearrange from a hexagonal configuration toward a triclinic, parallel chain subcell. Examination of the acyl chain methylene deformation modes at low temperatures allows a determination of DPPS microdomain sizes, which decrease upon the addition of DPPC-d(62) in the absence of Mg(2+). On adding Mg(2+), a uniform DPPS domain size is observed in the binary mixtures, In either the presence or absence of Mg(2+), DPPC-d(62) aggregates remain in a configuration for which microdomain sizes are not spectroscopically measurable. Analysis of the acyl chain methylene deformation modes for DPPC-d(62) in the binary system suggests that clusters of the deuterated lipids are distributed throughout the DPPS matrix. Light scattering and fluorescence measurements indicate that Mg(2+) induces both the aggregation and the fusion of the lipid assemblies as a function of the ratio of DPPS to DPPC. The structural reorganizations of the lipid microdomains within the DPPS-DPPC bilayer are interpreted in the context of current concepts regarding lipid bilayer fusion.

TI Increased mortality and AIDS-like immunopathology in wild chimpanzees infected with SIVcpz SO NATURE LA English DT Article ID GOMBE NATIONAL-PARK; IMMUNODEFICIENCY VIRUS-INFECTION; IMMUNE ACTIVATION; HIV-INFECTION; T-CELLS; POPULATION; TRANSMISSION; RESISTANCE; COMMUNITY; TANZANIA AB African primates are naturally infected with over 40 different simian immunodeficiency viruses (SIVs), two of which have crossed the species barrier and generated human immunodeficiency virus types 1 and 2 (HIV-1 and HIV-2)(1,2). Unlike the human viruses, however, SIVs do not generally cause acquired immunodeficiency syndrome (AIDS) in their natural hosts(3). Here we show that SIVcpz, the immediate precursor of HIV-1, is pathogenic in free-ranging chimpanzees. By following 94 members of two habituated chimpanzee communities in Gombe National Park, Tanzania, for over 9 years, we found a 10- to 16-fold higher age-corrected death hazard for SIVcpz-infected (n = 17) compared to uninfected (n = 77) chimpanzees. We also found that SIVcpz-infected females were less likely to give birth and had a higher infant mortality rate than uninfected females. Immunohistochemistry and in situ hybridization of post-mortem spleen and lymph node samples from three infected and two uninfected chimpanzees revealed significant CD4(+) T-cell depletion in all infected individuals, with evidence of high viral replication and extensive follicular dendritic cell virus trapping in one of them. One female, who died within 3 years of acquiring SIVcpz, had histopathological findings consistent with end-stage AIDS. These results indicate that SIVcpz, like HIV-1, is associated with progressive CD4(+) T-cell loss, lymphatic tissue destruction and premature death. These findings challenge the prevailing view that all natural SIV infections are non-pathogenic and suggest that SIVcpz has a substantial negative impact on the health, reproduction and lifespan of chimpanzees in the wild.

She recognizes that study procedures, particularly echocardiography, may identify and diagnose conditions that are not treatable within the local health system due to resource constraints. Aware that some of these needs may be serious, as well as difficult and costly to treat, she asks the bioethics consultation service for assistance in determining the extent to which she as an investigator has a responsibility to provide clinical care for conditions that she finds while conducting the study. This article reviews the issue of investigators' responsibilities to meet participants' needs for ancillary care and argues that investigators can have a responsibility to provide care for a wide range of health needs, including at times care for conditions not connected to the research question or study procedures. That responsibility, however, is significantly limited by the depth of the investigator's relationship with participants and the resource demands of providing such care.

We generated lines of Caenorhabditis elegans expressing neuronally directed human LRRK2. Expressing human LRRK2 increased nematode survival in response to rotenone or paraquat, which are agents that cause mitochondrial dysfunction. Protection by G2019S, R1441C, or kinase-dead LRRK2 was less than protection by wild-type LRRK2. Knockdown of lrk-1, the endogenous ortholog of LRRK2 in C. elegans, reduced survival associated with mitochondrial dysfunction. C. elegans expressing LRRK2 showed rapid loss of dopaminergic markers (DAT::GFP fluorescence and dopamine levels) beginning in early adulthood. Loss of dopaminergic markers was greater for the G2019S LRRK2 line than for the wild-type line. Rotenone treatment induced a larger loss of dopamine markers in C. elegans expressing G2019S LRRK2 than in C. elegans expressing wild-type LRRK2; however, loss of dopaminergic markers in the G2019S LRRK2 nematode lines was not statistically different from that in the control line. These data suggest that LRRK2 plays an important role in modulating the response to mitochondrial inhibition and raises the possibility that mutations in LRRK2 selectively enhance the vulnerability of dopaminergic neurons to a stressor associated with Parkinson's disease.

TI Trends in Cardiovascular Disease Risk Factors in Individuals With and Without Diabetes Mellitus in the Framingham Heart Study SO CIRCULATION LA English DT Article DE diabetes mellitus; risk factors; cholesterol; blood pressure; obesity ID PLACEBO-CONTROLLED TRIAL; BLOOD-PRESSURE; GLUCOSE CONTROL; MICROVASCULAR COMPLICATIONS; UNITED-STATES; US ADULTS; TYPE-2; HYPERTENSION; ATORVASTATIN; ASSOCIATION AB Background-Individuals with diabetes mellitus are at 2-to 3-fold increased risk for cardiovascular disease (CVD) relative to those without diabetes. Our objective was to examine CVD risk factor level changes among individuals with and without type 2 diabetes mellitus from 1970 to 2005 in the Framingham Heart Study. Methods and Results-We included 4195 participants (3990 with no diabetes and 205 with diabetes) 50 years of age and 3495 participants (3178 with no diabetes and 317 with diabetes) 60 years of age. Contemporaneous CVD risk factor levels were measured; linear regression models were used to assess the interaction between diabetes status and calendar year on CVD risk factor levels. Among 50-year-olds without diabetes mellitus, there was an increase in body mass index of 0.39 kg/m(2) per 10 years, whereas for those with diabetes, there was an increase of 2.52 kg/m2 (P value for the diabetes-by-calendar year interaction [P for interaction] < 0.001). For low-density lipoprotein cholesterol, the mean decrease was - 7.43 mg/dL per decade (nondiabetes) and - 15.5 mg/dL for diabetes (P for interaction = 0.002). For systolic blood pressure, the mean decrease was - 3.35 mm Hg per decade (nondiabetes) and - 3.50 mm Hg for diabetes (P for interaction = 0.97). The direction of the trends for those with diabetes relative to those without diabetes was similar for 60-year-olds. Conclusions-Compared with individuals without diabetes mellitus, individuals with diabetes experienced a greater increase in body mass index, a greater decrease in low-density lipoprotein cholesterol, and a similar magnitude of decline in systolic blood pressure. Individuals with diabetes mellitus have not experienced the necessary declines in CVD risk factors to overcome their increased risk of CVD. Further efforts are needed to aggressively control CVD risk factors among individuals with diabetes mellitus. (Circulation. 2009; 120: 212-220.)

However, the mechanism for this protection is not clear. We hypothesize that estrogen protects by ER-beta activation, which leads to S-nitrosylation (SNO) of key cardioprotective proteins. Methods and Results-We treated ovariectomized C57BL/6J mice with the ER-beta selective agonist 2,2-bis(4-hydroxyphenyl)- proprionitrile (DPN), 17 beta-estradiol (E2), or vehicle using Alzet minipumps for 2 weeks. Isolated hearts were Langendorff perfused and subjected to ischemia and reperfusion. Compared with vehicle-treated hearts, DPN-and E2-treated hearts had significantly better postischemic functional recovery and decreased infarct size. To test the specificity of DPN, we treated ER-beta-knockout mice with DPN. However, no cardioprotective effect of DPN was found in ER-beta-knockout mice, indicating that the DPN-induced cardioprotection occurs through the activation of ER-beta. Using DyLight-maleimide fluors and a modified biotin switch method, we used a 2-dimensional DyLight fluorescence difference gel electrophoresis proteomic method to quantify differences in SNO of proteins. DPN-and E2-treated hearts showed an increase in SNO of a number of proteins. Interestingly, many of these proteins also had been shown to have increased SNO in preconditioned hearts. In addition, the DPN-induced cardioprotection and increased SNO were abolished by treatment with a nitric oxide synthase inhibitor. Conclusion-The activation of ER-beta by DPN treatment leads to increased protein SNO and cardioprotection against ischemia/reperfusion injury, suggesting that long-term estrogen exposure protects hearts largely via activation of ER-beta and nitric oxide/SNO signaling.

The duration of transition paths is the tiny fraction of the time in an equilibrium single-molecule trajectory when the process actually happens. Here, we report the determination of an upper bound for the transition path time for protein folding from photon-by-photon trajectories. FRET trajectories were measured on single molecules of the dye-labeled, 56-residue 2-state protein GB1, immobilized on a glass surface via a biotin-streptavidin-biotin linkage. Characterization of individual emitted photons by their wavelength, polarization, and absolute and relative time of arrival after picosecond excitation allowed the determination of distributions of FRET efficiencies, donor and acceptor lifetimes, steady state polarizations, and waiting times in the folded and unfolded states. Comparison with the results for freely diffusing molecules showed that immobilization has no detectable effect on the structure or dynamics of the unfolded protein and only a small effect on the folding/unfolding kinetics. Analysis of the photon-by-photon trajectories yields a transition path time <200 mu s, >10,000 times shorter than the mean waiting time in the unfolded state (the inverse of the folding rate coefficient). Szabo's theory for diffusive transition paths shows that this upper bound for the transition path time is consistent with previous estimates of the Kramers preexponential factor for the rate coefficient, and predicts that the transition path time is remarkably insensitive to the folding rate, with only a 2-fold difference for rate coefficients that differ by 10(5)-fold.

We report a relationship between mitochondrial form and cell cycle control at the G(1)-S boundary. Mitochondria convert from isolated, fragmented elements into a hyperfused, giant network at G(1)-S transition. The network is electrically continuous and has greater ATP output than mitochondria at any other cell cycle stage. Depolarizing mitochondria at early G(1) to prevent these changes causes cell cycle progression into S phase to be blocked. Inducing mitochondrial hyperfusion by acute inhibition of dynamin-related protein-1 (DRP1) causes quiescent cells maintained without growth factors to begin replicating their DNA and coincides with buildup of cyclin E, the cyclin responsible for G(1)-to-S phase progression. Prolonged or untimely formation of hyperfused mitochondria, through chronic inhibition of DRP1, causes defects in mitotic chromosome alignment and S-phase entry characteristic of cyclin E overexpression. These findings suggest a hyperfused mitochondrial system with specialized properties at G(1)-S is linked to cyclin E buildup for regulation of G(1)-to-S progression.

TI MiR-21 is an EGFR-regulated anti-apoptotic factor in lung cancer in never-smokers SO PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA LA English DT Article DE apoptosis; microRNA; microarray; EGFR-TKI; therapeutic target ID CHRONIC LYMPHOCYTIC-LEUKEMIA; MICRORNA EXPRESSION; GEFITINIB RESISTANCE; DOWN-REGULATION; MUTATIONS; RECEPTOR; GENE; PROGNOSIS; GROWTH; PROFILES AB Fifteen percent of lung cancer cases occur in never-smokers and show characteristics that are molecularly and clinically distinct from those in smokers. Epidermal growth factor receptor (EGFR) gene mutations, which are correlated with sensitivity to EGFR-tyrosine kinase inhibitors (EGFR-TKIs), are more frequent in never-smoker lung cancers. In this study, microRNA (miRNA) expression profiling of 28 cases of never-smoker lung cancer identified aberrantly expressed miRNAs, which were much fewer than in lung cancers of smokers and included miRNAs previously identified (e. g., up-regulated miR-21) and unidentified (e. g., down-regulated miR-138) in those smoker cases. The changes in expression of some of these miRNAs, including miR-21, were more remarkable in cases with EGFR mutations than in those without these mutations. A significant correlation between phosphorylated-EGFR (p-EGFR) and miR-21 levels in lung carcinoma cell lines and the suppression of miR-21 by an EGFR-TKI, AG1478, suggest that the EGFR signaling is a pathway positively regulating miR-21 expression. In the never-smoker-derived lung adenocarcinoma cell line H3255 with mutant EGFR and high levels of p-EGFR and miR-21, antisense inhibition of miR-21 enhanced AG1478-induced apoptosis. In a never-smoker-derived adenocarcinoma cell line H441 with wildtype EGFR, the antisense miR-21 not only showed the additive effect with AG1478 but also induced apoptosis by itself. These results suggest that aberrantly increased expression of miR-21, which is enhanced further by the activated EGFR signaling pathway, plays a significant role in lung carcinogenesis in never-smokers, as well as in smokers, and is a potential therapeutic target in both EGFR-mutant and wild-type cases.

TI Claudin-containing exosomes in the peripheral circulation of women with ovarian cancer SO BMC CANCER LA English DT Article ID TUMOR-DERIVED EXOSOMES; DIFFERENTIAL GENE-EXPRESSION; SQUAMOUS-CELL CARCINOMA; TIGHT JUNCTION PROTEINS; REDUCED EXPRESSION; POTENTIAL MARKERS; SEROUS PAPILLARY; CA125; OVEREXPRESSION; IDENTIFICATION AB Background: The absence of highly sensitive and specific serum biomarkers makes mass screening for ovarian cancer impossible. The claudin proteins are frequently overexpressed in ovarian cancers, but their potential as prognostic, diagnostic, or detection markers remains unclear. Here, we have explored the possible use of these proteins as screening biomarkers for ovarian cancer detection. Methods: Claudin protein shedding from cells was examined by immunoblotting of conditioned culture media. The presence of claudins in exosomes released from ovarian cancer cells was demonstrated by sucrose gradient separation and immunogold electron microscopy experiments. Claudin-4-containing exosomes in the plasma of ovarian cancer patients were evaluated in a pilot panel of 63 ovarian cancer patients and 50 healthy volunteers. The CA125 marker was also assessed in these samples and compared with claudin-4 positivity. Results: We show that full-length claudins can be shed from ovarian cancer cells in culture and found in the media as part of small lipid vesicles known as exosomes. Moreover, 32 of 63 plasma samples from ovarian cancer patients exhibited the presence of claudin-4-containing exosomes. In contrast, only one of 50 samples from individuals without cancer exhibited claudin-4-positive exosomes. In our small panel, at a specificity of 98%, the claudin-4 and CA125 tests had sensitivities of 51% and 71%, respectively. The two tests did not appear to be independent and were strongly correlated. Conclusion: Our work shows for the first time that claudin-4 can be released from ovarian cancer cells and can be detected in the peripheral circulation of ovarian cancer patients. The development of sensitive assays for the detection of claudin-4 in blood will be crucial in determining whether this approach can be useful, alone or in combination with other screening methods, for the detection of ovarian cancer.

Previous investigations have used traditional epidemiological methods that are unable to identify the causative agent and from which dynamics of disease dispersion is difficult to discern. The objective of this study was to isolate, characterize and determine the genetic diversity and relatedness of M. bovis from major cattle rearing districts in Zambia by spoligotyping. A total of 695 carcasses were examined and 98 tissues had gross postmortem lesions compatible with BTB. Results: Forty-two out of the ninety-eight suspected tissues examined had culture properties characteristic of mycobacteria from which 31 isolates yielded interpretable spoligotypes. This technique showed good discriminatory power (HGDI = 0.98), revealing 10 different spoligotype patterns. Twenty-seven isolates belonged to one cluster with more than 95% similarity and inside the cluster, one predominant spoligotype was found in 20 (64.5%) of the isolates tested. The highest number of spoligotypes was observed among samples from Namwala district. Spoligotypes from 26 (83.9%) of the isolates belonged to five spoligotypes that have been reported before while the remaining 5 (16.1%) isolates had unique spoligotypes that are being reported for the first time; these have been assigned numbers SB1763 to SB1767. Five of the 6 districts had the predominant spoligotype (SB0120). Conclusion: The study has described the dispersion patterns of M. bovis in Zambian cattle for the first time and has identified 5 spoligotype patterns specific to Zambia. The observation of an overlap in the spoligotype pattern SB0120 in 5 of the 6 districts suggests the probability of sharing a common source of infection.

TI Elevated Biomarkers of Inflammation Are Associated With Reduced Survival Among Breast Cancer Patients SO JOURNAL OF CLINICAL ONCOLOGY LA English DT Article ID C-REACTIVE PROTEIN; SERUM-AMYLOID-A; PHYSICAL-ACTIVITY LEVELS; ACUTE-PHASE RESPONSE; CURATIVE RESECTION; CARCINOMA; PROGNOSIS AB Purpose Chronic inflammation is believed to contribute to the development and progression of breast cancer. Systemic C-reactive protein (CRP) and serum amyloid A (SAA) are measures of low-grade chronic inflammation and potential predictors of cancer survival. Patients and Methods We evaluated the relationship between circulating markers of inflammation and breast cancer survival using data from the Health, Eating, Activity, and Lifestyle (HEAL) Study (a multiethnic prospective cohort study of women diagnosed with stage 0 to IIIA breast cancer). Circulating concentrations of CRP and SAA were measured approximately 31 months after diagnosis and tested for associations with disease-free survival (approximately 4.1 years of follow-up) and overall survival (approximately 6.9 years of follow-up) in 734 disease-free breast cancer survivors. Cox proportional hazards models were used with adjustment for potential confounding factors to generate hazard ratios (HRs) and 95% CIs. Results Elevated SAA and CRP were associated with reduced overall survival, regardless of adjustment for age, tumor stage, race, and body mass index (SAA P trend < .0001; CRP P trend = .002). The HRs for SAA and CRP tertiles suggested a threshold effect on survival, rather than a dose-response relationship (highest v lowest tertile: SAA HR = 3.15; 95% CI, 1.73 to 5.65; CRP HR = 2.27; 95% CI, 1.27 to 4.08). Associations were similar and still significant after adjusting for self-reported history of cardiovascular events and censoring cardiovascular disease deaths. Elevated CRP and SAA were also associated with reduced disease-free survival, although these associations were of borderline significance (SAA P trend = .04; CRP P trend = .07). Conclusion Circulating SAA and CRP may be important prognostic markers for long-term survival in breast cancer patients, independent of race, tumor stage, and body mass index.

TI Effect of length biased sampling of unobserved sojourn times on the survival distribution when disease is screen detected SO STATISTICS IN MEDICINE LA English DT Article DE randomized screening trial; sojourn time; lead time; bivariate gamma distribution; clinical duration; periodic screening; HIP trial ID ESTIMATING LEAD TIME; NONPARAMETRIC-ESTIMATION; EMPIRICAL DISTRIBUTIONS; BREAST-CANCER; MODELS; RATES; MORTALITY; NEOPLASMS; DENSITY; TRIALS AB Data can arise as a length-biased sample rather than as a random sample; e.g. a sample of patients in hospitals or of network cable lines (experimental units with longer stays or longer lines have greater likelihoods of being sampled). The distribution arising from a single length-biased sampling (LBS) time has been derived (e.g. (The Statistical Analysis of Discrete Time Events. Oxford Press: London, 1972)) and applies when the observed outcome relates to the random variable subjected to LBS. Zelen (Breast Cancer: Trends in Research and Treatment. Raven Press: New York, 1976; 287-301) noted that cases of disease detected from a screening program likewise form a length-biased sample among all cases, since longer sojourn times afford greater likelihoods of being screen detected. In contrast to the samples on hospital stays and cable lines, however, the length-biased sojourns (preclinical durations) cannot be observed, although their subsequent clinical durations (survival times) are. This article quantifies the effect of LBS of the sojourn times (or pre-clinical durations) on the distribution of the observed clinical durations when cases undergo periodic screening for the early detection of disease. We show that, when preclinical and clinical durations are positively correlated, the mean, median, and quartiles of the distribution of the clinical duration from screen-detected cases can be substantially inflated-even in the absence of any benefit on survival from the screening procedure. Screening studies that report mean Survival time need to take account of the fact that, even in the absence of any real benefit, the mean survival among cases in the screen-detected group will be longer than that among interval cases or among cases that arise in the control arm, above and beyond lead time bias, simply by virtue of the LBS phenomenon.

TI Pathological manifestations of feline immunodeficiency virus (FIV) infection in wild African lions SO VIROLOGY LA English DT Article DE FIV; Lentivirus; Lions; Wild; Free-ranging; Pathology; Immune depletion ID FREE-RANGING LIONS; HIV-INFECTION; PANTHERA-LEO; RHESUS MACAQUES; DISEASE PROGRESSION; LENTIVIRUS INFECTION; PHYLOGENETIC ASPECTS; IMMUNE DYSFUNCTION; PUMA LENTIVIRUSES; TERM SURVIVAL AB Feline immunodeficiency virus (FIV) causes AIDS in the domestic cat (Felis catus) but has not been explicitly associated with AIDS pathology in any of the eight free-ranging species of Felidae that are endemic with circulating FIV strains. African lion (Panthera lea) populations are infected with lion-specific FIV strains (FIVple), yet there remains uncertainty about the degree to which FIV infection impacts their health. Reported CD4+ T-lymphocyte depletion in FIVple-infected lions and anecdotal reports of lion morbidity associated with FIV seroprevalence emphasize the concern as to whether FIVple is innocuous or pathogenic. Here we monitored clinical, biochemical, histological and serological parameters among FIVple-positive (N = 47) as compared to FIVple-negative (N = 17) lions anesthetized and sampled on multiple occasions between 1999 and 2006 in Botswana. Relative to uninfected lions, FIVple-infected lions displayed a significant elevation in the prevalence of AIDS-defining conditions: lymphadenopathy, gingivitis, tongue papillomas, dehydration, and poor coat condition, as well as displaying abnormal red blood cell parameters. depressed serum albumin, and elevated liver enzymes and gamma globulin. Spleen and lymph node biopsies from free-ranging FIVple-infected lions (N=9) revealed evidence of lymphoid depletion, the hallmark pathology documented in immunodeficiency virus infections of humans (HIV-1), macaques, and domestic cats. We conclude that over time FIVple infections in free-ranging lions can lead to adverse clinical, immunological, and pathological outcomes in some individuals that parallel sequelae caused by lentivirus infection in humans (HIV), Asian macaques (SIV) and domestic cats (FIVfca).

TI Circumcision in HIV-infected men and its effect on HIV transmission to female partners in Rakai, Uganda: a randomised controlled trial SO LANCET LA English DT Article ID IMMUNODEFICIENCY-VIRUS TYPE-1; DISCORDANT COUPLES; PREVENTION; AFRICA; COHORT; KENYA; WOMEN AB Background Observational studies have reported an association between male circumcision and reduced risk of HIV infection in female partners. We assessed whether circumcision in HIV-infected men would reduce transmission of the virus to female sexual partners. Methods 922 uncircumcised, HIV-infected, asymptomatic men aged 15-49 years with CD4-cell counts 350 cells per mu L or more were enrolled in this unblinded, randomised controlled trial in Rakai District, Uganda. Men were randomly assigned by computer-generated randomisation sequence to receive immediate circumcision (intervention; n=474) or circumcision delayed for 24 months (control; n=448). HIV-uninfected female partners of the randomised men were concurrently enrolled (intervention, n=93; control, n=70) and followed up at 6, 12, and 24 months, to assess HIV acquisition by male treatment assignment (primary outcome). A modified intention-to-treat (ITT) analysis, which included all concurrently enrolled couples in which the female partner had at least one follow-up visit over 24 months, assessed female HIV acquisition by use of survival analysis and Cox proportional hazards modelling. This trial is registered with ClinicalTrials.gov, number NCT00124878. Findings The trial was stopped early because of futility. 92 couples in the intervention group and 67 couples in the control group were included in the modified ITT analysis. 17 (18%) women in the intervention group and eight (12%) women in the control group acquired HIV during follow-up (p=0.36). Cumulative probabilities of female HIV infection at 24 months were 21.7% (95% Cl 12.7-33.4) in the intervention group and 13.4% (6.7-25.8) in the control group (adjusted hazard ratio 1.49, 95% CI 0.62-3.57; p=0.368). Interpretation Circumcision of HIV-infected men did not reduce HIV transmission to female partners over 24 months; longer-term effects could not be assessed. Condom use after male circumcision is essential for HIV prevention.

Methods: Fifteen HIV-infected men and women on a regimen containing LPV/r and with evidence of hyperinsulinemia and/or dyslipidemia were randomized to continue LPV/r or to switch to ATV/r (ATV 300 mg and ritonavir 100 mg daily) for 6 months. The primary endpoint was change in thigh muscle glucose uptake as measured by positron emission tomography. Secondary endpoints included abdominal visceral adipose tissue, fasting lipids, and safety parameters. The difference over time between treatment groups (treatment effect of ATV/r relative to LPV/r) was determined by repeated measures ANCOVA. Results: After 6 months, anterior thigh muscle glucose uptake increased significantly (treatment effect +18.2 +/- 5.9 mu mol/kg per min, ATV/r vs. LPV/r, P=0.035), and visceral adipose tissue area decreased significantly in individuals who switched to ATV/r (treatment effect -31 +/- 11 cm(2), ATV/r vs. LPV/r, P=0.047). Switching to ATV/r significantly decreased triglyceride (treatment effect -182 +/- 64 mg/dl, ATV/r vs. LPV/r, P=0.02) and total cholesterol (treatment effect -23 +/- 8 mg/dl, ATV/r vs. LPV/r, P=0.01), whereas high-density lipoprotein and low-density lipoprotein did not change significantly. Fasting glucose also decreased significantly following switch to ATV/r (treatment effect -15 +/- 4 mg/dl, ATV/r vs. LPV/r, P=0.002). Conclusion: Switching from LPV/r to ATV/r significantly increases glucose uptake by muscle, decreases abdominal visceral adipose tissue, improves lipid parameters, and decreases fasting glucose over 6 months.

TI Integrin-Dependent Organization and Bidirectional Vesicular Traffic at Cytotoxic Immune Synapses SO IMMUNITY LA English DT Article ID CELL IMMUNOLOGICAL SYNAPSE; T-CELLS; RING JUNCTION; NK CELLS; ACTIVATION; RECEPTORS; COSTIMULATION; POLARIZATION; RECOGNITION; CONTRIBUTES AB Cytotoxic lymphocytes kill target cells by releasing the content of secretory lysosomes at the immune synapse. To understand the dynamics and control of cytotoxic immune synapses, we imaged human primary, live natural killer cells on lipid bilayers carrying ligands of activation receptors. Formation of an organized synapse was dependent on the presence of the beta 2 integrin ligand ICAM-1. Ligands of coactivation receptors 2B4 and NKG2D segregated into central and peripheral regions, respectively. Lysosomal protein LAMP-1 that was exocytosed during degranulation accumulated in a large and spatially stable cluster, which overlapped with a site of membrane internalization. Lysosomal compartments reached the plasma membrane at focal points adjacent to centrally accumulated LAMP-1. Imaging of fixed cells revealed that perforin-containing granules were juxtaposed to an intracellular compartment where exocytosed LAMP-1 was retrieved. Thus, cytotoxic immune synapses include a central region of bidirectional vesicular traffic, which is controlled by integrin signaling.

TI A Regulatory Loop Composed of RAP80-HDM2-p53 Provides RAP80-enhanced p53 Degradation by HDM2 in Response to DNA Damage SO JOURNAL OF BIOLOGICAL CHEMISTRY LA English DT Article ID TUMOR SUPPRESSION; POSTTRANSLATIONAL MODIFICATIONS; DEPENDENT PHOSPHORYLATION; TRANSCRIPTION-FACTOR; REPAIR PROTEINS; BREAST-CANCER; BRCA1 PROTEIN; BINDING-SITES; HUMAN GENOME; RAP80 AB The ubiquitin interaction motif-containing protein RAP80 plays a key role in DNA damage response signaling. Using genomic and functional analysis, we established that the expression of the RAP80 gene is regulated in a DNA damage-responsive manner by the master regulator p53. This regulation occurs at the transcriptional level through a noncanonical p53 response element in the RAP80 promoter. Although it is inducible by p53, RAP80 is also able to regulate p53 through an association with both p53 and the E3 ubiquitin ligase HDM2, providing HDM2-dependent enhancement of p53 poly-ubiquitination. Depletion of RAP80 by small interfering RNA stabilizes p53, which, following DNA damage, results in an increased transactivation of several p53 target genes as well as greater apoptosis. Consistent with these observations, exogenous expression of RAP80 selectively inhibits p53-dependent transactivation of target genes in an mdm2-dependent manner in MEF cells. Thus, we identify a new DNA damage-associated role for RAP80. It can function in an autoregulatory loop consisting of RAP80, HDM2, and the p53 master regulatory network, implying an important role for this loop in genome stability and oncogenesis.

TI Structural Determinants of G-protein alpha Subunit Selectivity by Regulator of G-protein Signaling 2 (RGS2) SO JOURNAL OF BIOLOGICAL CHEMISTRY LA English DT Article ID GTPASE-ACTIVATING PROTEINS; MYOCARDIAL HYPERTROPHY; CIONA-INTESTINALIS; SEQUENCE ALIGNMENT; PHOSPHOLIPASE-C; RECEPTOR; PRESSURE; ANXIETY; DOMAIN; HYPERTENSION AB "Regulator of G-protein signaling" (RGS) proteins facilitate the termination of G protein-coupled receptor (GPCR) signaling via their ability to increase the intrinsic GTP hydrolysis rate of G alpha subunits (known as GTPase-accelerating protein or "GAP" activity). RGS2 is unique in its in vitro potency and selectivity as a GAP for G alpha(q) subunits. As many vasoconstrictive hormones signal via G(q) heterotrimer-coupled receptors, it is perhaps not surprising that RGS2-deficient mice exhibit constitutive hypertension. However, to date the particular structural features within RGS2 determining its selectivity for G alpha(q) over G alpha(i/o) substrates have not been completely characterized. Here, we examine a trio of point mutations to RGS2 that elicits G alpha(i)-directed binding and GAP activities without perturbing its association with G alpha(q). Using x-ray crystallography, we determined a model of the triple mutant RGS2 in complex with a transition state mimetic form of G alpha(i) at 2.8-angstrom resolution. Structural comparison with unliganded, wild type RGS2 and of other RGS domain/G alpha complexes highlighted the roles of these residues in wild type RGS2 that weaken G alpha(i) subunit association. Moreover, these three amino acids are seen to be evolutionarily conserved among organisms with modern cardiovascular systems, suggesting that RGS2 arose from the R4-subfamily of RGS proteins to have specialized activity as a potent and selective G alpha(q) GAP that modulates cardiovascular function.

The durable inhibition of HIV-1 replication by RNA interference has been impeded, however, by a high mutation rate when viral sequences are targeted and by cytotoxicity when cellular genes are knocked down. To identify cellular proteins that contribute to HIV-1 replication that can be chronically silenced without significant cytotoxicity, we employed a shRNA library that targets 54,509 human transcripts. We used this library to select a comprehensive population of Jurkat T-cell clones, each expressing a single discrete shRNA. The Jurkat clones were then infected with HIV-1. Clones that survived viral infection represent moieties silenced for a human mRNA needed for virus replication, but whose chronic knockdown did not cause cytotoxicity. Overall, 252 individual Jurkat mRNAs were identified. Twenty-two of these mRNAs were secondarily verified for their contributions to HIV-1 replication. Five mRNAs, NRF1, STXBP2, NCOA3, PRDM2, and EXOSC5, were studied for their effect on steps of the HIV-1 life cycle. We discuss the similarities and differences between our shRNA findings for HIV-1 using a spreading infection assay in human Jurkat T-cells and results from other investigators who used siRNA-based screenings in HeLa or 293T cells.

Sequence analysis of the C-terminal polymerase region of pol gamma revealed a cluster of four Alpers mutations at highly conserved residues in the thumb subdomain (G848S, c.2542g -> a; T851A, c.2551a -> g; R852C, c.2554c -> t; R853Q, c.2558g -> a) and two Alpers mutations at less conserved positions in the adjacent palm subdomain (Q879H, c.2637g -> t and T885S, c.2653a -> t). Biochemical characterization of purified, recombinant forms of pol gamma revealed that Alpers mutations in the thumb subdomain reduced polymerase activity more than 99% relative to the wild-type enzyme, whereas the palm subdomain mutations retained 50-70% wildtype polymerase activity. All six mutant enzymes retained physical and functional interaction with the pol gamma accessory subunit (p55), and none of the six mutants exhibited defects in misinsertion fidelity in vitro. However, differential DNA binding by these mutants suggests a possible orientation of the DNA with respect to the polymerase during catalysis. To our knowledge this study represents the first structure-function analysis of the thumb subdomain in pol gamma and examines the consequences of mitochondrial disease mutations in this region.

Deletion of the RPB9 gene shows synthetic lethality with the low fidelity rpb1-E1103G mutation localized in the trigger loop, a mobile element of the catalytic Rpb1 subunit, which has been shown to control transcription fidelity. Similar to the rpb1-E1103G mutation, the RPB9 deletion substantially enhances NTP misincorporation and increases the rate of mismatch extension with the next cognate NTP in vitro. Using pre-steady state kinetic analysis, we show that RPB9 deletion promotes sequestration of NTPs in the polymerase active center just prior to the phosphodiester bond formation. We propose a model in which the Rpb9 subunit controls transcription fidelity by delaying the closure of the trigger loop on the incoming NTP via interaction between the C-terminal domain of Rpb9 and the trigger loop. Our findings reveal a mechanism for regulation of transcription fidelity by protein factors located at a large distance from the active center of RNA polymerase II.

We carried out a fine-mapping study of this region in Orthodox Ashkenazi Jewish (ASHK) and Old Order Amish (OOA) families to confirm linkage and narrow the candidate region. Methods: Families were recruited from ASHK and OOA American communities. The samples included: 402 individuals in 53 OOA families; and 596 members in 68 ASHK families. Families were ascertained to contain multiple myopic individuals. Genotyping of 1,367 SNPs was carried out within a 35cM (similar to 23.9 Mb) candidate QTL region on 1p34-36. Multipoint variance components (VC) and regression-based (REG) linkage analyses were carried out separately in OOA and ASHK groups, and in a combined analysis that included all families. Results: Evidence of linkage of refractive error was found in both OOA (VC LOD=3.45, REG LOD=3.38 at similar to 59 cM) and ASHK families (VC LOD=3.12, REG LOD=4.263 at similar to 66 cM). Combined analyses showed three highly significant linkage peaks, separated by similar to 11 cM (or 10 Mb), within the candidate region. Conclusion: In a fine-mapping linkage study of OOA and ASHK families, we have confirmed linkage of refractive error to a QTL on 1p. The area of linkage has been narrowed down to a gene-rich region at 1p34.2-35.1 containing similar to 124 genes.

TI Demographic Variability, Vaccination, and the Spatiotemporal Dynamics of Rotavirus Epidemics SO SCIENCE LA English DT Article ID UNITED-STATES; SPATIAL HIERARCHIES; TRAVELING-WAVES; SEASONALITY; DIARRHEA; EFFICACY; MEASLES; SAFETY; GASTROENTERITIS; PROTECTION AB Historically, annual rotavirus activity in the United States has started in the southwest in late fall and ended in the northeast 3 months later; this trend has diminished in recent years. Traveling waves of infection or local environmental drivers cannot account for these patterns. A transmission model calibrated against epidemiological data shows that spatiotemporal variation in birth rate can explain the timing of rotavirus epidemics. The recent large-scale introduction of rotavirus vaccination provides a natural experiment to further test the impact of susceptible recruitment on disease dynamics. The model predicts a pattern of reduced and lagged epidemics postvaccination, closely matching the observed dynamics. Armed with this validated model, we explore the relative importance of direct and indirect protection, a key issue in determining the worldwide benefits of vaccination.

CA Blood & Marrow Transplant Clin Tri TI Etanercept, mycophenolate, denileukin, or pentostatin plus corticosteroids for acute graft-versus-host disease: a randomized phase 2 trial from the Blood and Marrow Transplant Clinical Trials Network SO BLOOD LA English DT Article; Proceedings Paper CT 50th Annual Meeting of the American-Society-of-Hematology/ASH/ASCO Joint Symposium CY DEC 06-09, 2008 CL San Francisco, CA SP Amer Soc Hematol (ASH), Sanofi Aventis U.S. ID INITIAL THERAPY; CHRONIC GVHD; METHOTREXATE; CYCLOSPORINE; PROPHYLAXIS; PREDNISONE; DIFTITOX; EFFICACY; STEROIDS; MODERATE AB Acute graft-versus-host disease (aGVHD) is the primary limitation of allogeneic hematopoietic cell transplantation. Corticosteroids remain the standard initial therapy, yet only 25% to 41% of patients completely respond. This randomized, 4-arm, phase 2 trial was designed to identify the most promising agent(s) for initial therapy for aGVHD. Patients were randomized to receive methylprednisolone 2 mg/kg per day plus etanercept, mycophenolate mofetil (MMF), denileukin diftitox (denileukin), or pentostatin. Patients (n = 180) were randomized; their median age was 50 years (range, 7.5-70 years). Myeloablative conditioning represented 66% of transplants. Grafts were peripheral blood (61%), bone marrow (25%), or umbilical cord blood (14%); 53% were from unrelated donors. Patients who received MMF for prophylaxis (24%) were randomized to a non-MMF arm. At randomization, aGVHD was grade I to II (68%), III to IV (32%), and (53%) had visceral organ involvement. Day 28 complete response rates were etanercept 26%, MMF 60%, denileukin 53%, and pentostatin 38%. Corresponding 9-month overall survival was 47%, 64%, 49%, and 47%, respectively. Cumulative incidences of severe infections were as follows: etanercept 48%, MMF 44%, denileukin 62%, and pentostatin 57%. Efficacy and toxicity data suggest the use of MMF plus corticosteroids is the most promising regimen to compare against corticosteroids alone in a definitive phase 3 trial.

TI Gene therapy with human and mouse T-cell receptors mediates cancer regression and targets normal tissues expressing cognate antigen SO BLOOD LA English DT Article ID TUMOR-INFILTRATING LYMPHOCYTES; ADOPTIVE IMMUNOTHERAPY; METASTATIC MELANOMA; TCR; AUTOIMMUNITY; RECOGNITION; PERSISTENCE AB Gene therapy of human cancer using genetically engineered lymphocytes is dependent on the identification of highly reactive T-cell receptors (TCRs) with antitumor activity. We immunized transgenic mice and also conducted high-throughput screening of human lymphocytes to generate TCRs highly reactive to melanoma/melanocyte antigens. Genes encoding these TCRs were engineered into retroviral vectors and used to transduce autologous peripheral lymphocytes administered to 36 patients with metastatic melanoma. Transduced patient lymphocytes were CD45RA(-) and CD45RO(+) after ex vivo expansion. After infusion, the persisting cells displayed a CD45RA(+) and CD45RO(-) phenotype. Gene-engineered cells persisted at high levels in the blood of all patients 1 month after treatment, responding patients with higher ex vivo antitumor reactivity than nonresponders. Objective cancer regressions were seen in 30% and 19% of patients who received the human or mouse TCR, respectively. However, patients exhibited destruction of normal melanocytes in the skin, eye, and ear, and sometimes required local steroid administration to treat uveitis and hearing loss. Thus, T cells expressing highly reactive TCRs mediate cancer regression in humans and target rare cognate -antigen-containing cells throughout the body, a finding with important implications for the gene therapy of cancer.

TI Type 17 CD8(+) T cells display enhanced antitumor immunity SO BLOOD LA English DT Article ID EFFECTOR; CANCER; DIFFERENTIATION; IMMUNOTHERAPY; EOMESODERMIN; INDUCTION; REGRESSION; DISTINCT; THERAPY; TH17 AB Interleukin-17 (IL-17)-secreting CD8(+) T cells have been described, but they have not been thoroughly studied and they do not have a known role in cancer immunotherapy. We skewed CD8(+) T cells to secrete IL-17 through priming in Th17-polarizing conditions. IL-17-producing CD8(+) T cells demonstrated reduced expression of Eomes and diminished cytolytic differentiation in vitro. However, after adoptive transfer, these cells converted to interferon-gamma-producing effector cells and mediated regression of large, established tumors. This improved antitumor immunity was associated with increased expression of IL-7R-alpha, decreased expression of killer cell lectin-like receptor G1, and enhanced persistence of the transferred cells. This report is the first description of a cancer therapy with IL-17 secreting CD8(+) T cells. These findings have implications for the improvement of CD8(+) T cell-based adoptive immunotherapy.

TI The active form of DNA polymerase V is UmuD ' C-2-RecA-ATP SO NATURE LA English DT Article ID SINGLE-STRANDED-DNA; ESCHERICHIA-COLI; RECA PROTEIN; UV-MUTAGENESIS; REPLICATION; DEFICIENT; MUTATIONS; REPAIR; UMUC; PURIFICATION AB DNA-damage-induced SOS mutations arise when Escherichia coli DNA polymerase (pol) V, activated by a RecA nucleoprotein filament (RecA*), catalyses translesion DNA synthesis. Here we address two longstanding enigmatic aspects of SOS mutagenesis, the molecular composition of mutagenically active pol V and the role of RecA*. We show that RecA* transfers a single RecA-ATP stoichiometrically from its DNA 39-end to free polV (UmuD'C-2) to form an active mutasome (polV Mut) with the composition UmuD'C-2-RecA-ATP. PolV Mut catalyses TLS in the absence of RecA* and deactivates rapidly upon dissociation from DNA. Deactivation occurs more slowly in the absence of DNA synthesis, while retaining RecA-ATP in the complex. Reactivation of polV Mut is triggered by replacement of RecA-ATP from RecA*. Thus, the principal role of RecA* in SOS mutagenesis is to transfer RecA-ATP to pol V, and thus generate active mutasomal complex for translesion synthesis.

TI Rapamycin fed late in life extends lifespan in genetically heterogeneous mice SO NATURE LA English DT Article ID INTERVENTIONS TESTING PROGRAM; CALORIC RESTRICTION; SIGNALING PATHWAY; TOR; METABOLISM; EXTENSION; ELEGANS; DESIGN; TARGET; YEAST AB Inhibition of the TOR signalling pathway by genetic or pharmacological intervention extends lifespan in invertebrates, including yeast, nematodes and fruitflies(1-5); however, whether inhibition of mTOR signalling can extend lifespan in a mammalian species was unknown. Here we report that rapamycin, an inhibitor of the mTOR pathway, extends median and maximal lifespan of both male and female mice when fed beginning at 600 days of age. On the basis of age at 90% mortality, rapamycin led to an increase of 14% for females and 9% for males. The effect was seen at three independent test sites in genetically heterogeneous mice, chosen to avoid genotype-specific effects on disease susceptibility. Disease patterns of rapamycin-treated mice did not differ from those of control mice. In a separate study, rapamycin fed to mice beginning at 270 days of age also increased survival in both males and females, based on an interim analysis conducted near the median survival point. Rapamycin may extend lifespan by postponing death from cancer, by retarding mechanisms of ageing, or both. To our knowledge, these are the first results to demonstrate a role for mTOR signalling in the regulation of mammalian lifespan, as well as pharmacological extension of lifespan in both genders. These findings have implications for further development of interventions targeting mTOR for the treatment and prevention of age-related diseases.

TI Remote Control of Neuronal Activity in Transgenic Mice Expressing Evolved G Protein-Coupled Receptors SO NEURON LA English DT Article ID CONDITIONAL EXPRESSION; IN-VIVO; G(I)-COUPLED RECEPTOR; MAMMALIAN NEURONS; M-CHANNEL; OSCILLATIONS; INHIBITION; LIGAND AB Examining the behavioral consequences of selective CNS neuronal activation is a powerful tool for elucidating mammalian brain function in health and disease. Newly developed genetic, pharmacological, and optical tools allow activation of neurons with exquisite spatiotemporal resolution; however, the inaccessibility to light of widely distributed neuronal populations and the invasiveness required for activation by light or infused ligands limit the utility of these methods. To overcome these barriers, we created transgenic mice expressing an evolved G protein-coupled receptor (hM3Dq) selectively activated by the pharmacologically inert, orally bioavailable drug clozapine-N-oxide (CNO). Here, we expressed hM3Dq in forebrain principal neurons. Local field potential and single-neuron recordings revealed that peripheral administration of CNO activated hippocampal neurons selectively in h1M3Dq-expressing mice. Behavioral correlates of neuronal activation included increased locomotion, stereotypy, and limbic seizures. These results demonstrate a powerful chemical-genetic tool for remotely controlling the activity of discrete populations of neurons in vivo.

Here we show that when macaque monkeys are offered a water reward of variable magnitude, they seek advance information about its size. Furthermore, the same midbrain dopamine neurons that signal the expected amount of water also signal the expectation of information, in a manner that is correlated with the strength of the animal's preference. Our data show that single dopamine neurons process both primitive and cognitive rewards, and suggest that current theories of reward-seeking must be revised to include information-seeking.

However, for protection from inhalational challenge with this bacterium, we wondered if mucosally administered immunotherapy might be more effective. Therefore, we administered cationic liposome-DNA complexes (CLDC), which are potent activators of innate immunity, intranasally (i.n.) and assessed the effectiveness of protection from lethal inhalational challenge with F tularensis. We found that pretreatment by i.n. administration of CLDC 24 h prior to bacterial challenge elicited nearly complete protection of BALB/c mice from lethal challenge with E tularensis LV5 strain. We also observed that mucosal CLDC immunotherapy provided a statistically significant increase in survival time in mice challenged with the highly virulent F tularensis Schu4 strain. Protection was associated with a significant reduction in bacterial burden in the lungs, liver, and spleen. Mucosal administration of CLDC elicited significantly increased expression of IL-12, IFN-gamma, TNF-alpha, IFN-beta and IFN-alpha genes in the lung as detected by real-time quantitative PCR. In vitro treatment of E tularensis infected macrophages with CLDC-elicited cytokines also significantly suppressed intracellular replication of E tularensis in infected macrophages. In vivo, depletion of NK cells prior to administration of CLDC completely abolished the protective effects of CLDC immunotherapy. CLDC-elicited protection was also dependent on induction of IFN-gamma production in vivo. We conclude therefore that activation of local pulmonary innate immune responses is capable of eliciting significant protection from inhalational exposure to a virulent bacterial pathogen.

We evaluated the impact of pre-existing immunity to vaccinia virus on the induction of HIV-specific responses after immunization of healthy volunteers with a HIV-1 DNA prime-MVA boost vaccine. Following three priming immunizations with HIV-1 DNA plasmids, the volunteers were boosted with a single injection of recombinant MVA encoding HIV-1 proteins. Pre-existing immunity to vaccinia virus did not reduce the proportion of individuals who responded to HIV-1, but: did lower the magnitude of responses. Our results suggest that vaccinia-based vectors can be used to efficiently induce immune responses to vectored HIV-1 antigens, even in individuals with pre-existing immunity to vaccinia virus.

We have previously generated poxviral vectors expressing a TAA and a TRlad of COstimulatory Molecules (B7-1, ICAM-1, and LFA-3; TRICOM) as transgenes, including replication competent recombinant vaccinia (rV) or replication-defective modified vaccinia Ankara (MVA), to prime tumor-specific immune responses, and a replication-defective recombinant fowlpox (rF) to boost these responses. MVA is a potentially safer, replication-defective form of vaccinia virus with unique immunostimulatory properties that could make it a superior priming vaccine. Here, an MVA vector encoding a tumor antigen (CEA) and TRICOM was utilized (rMVA). A single rMVA-CEA/TRICOM vaccination induced greater expression of several serum cytokines associated with enhanced T-cell immunity than that seen with vaccinia. We hypothesized that this effect might "pre-condition" the vaccination site for a more effective boost. An rMVA-CEA/TRICOM prime followed 7 days later (but not 30 days later) by an rf-CEA/TRICOM boost at the same injection site (but not at a distal site) induced more potent CEA-specific T-cell responses, and superior CEA-specific immunity and antitumor activity, than rV-CEA/TRICOM followed by rF-CEA/TRICOM. This preconditioning effect was also observed using a heterologous antigen model, where priming with rMVA-CEA/TRICOM followed 7 days later by rF-LacZ/TRICOM enhanced beta-gal-specific immunity compared to rF-LacZ/TRICOM only. The studies reported here show for the first time that priming with rMVA followed 7 days later by an rF boost at the same injection site, versus a distal site, generates superior tumor-specific immunity and antitumor activity.

The analysis included 1,219 incident bladder cancer cases and 1,271 controls recruited in Spain in 1998-2001. Information on etiologic factors for bladder cancer was collected through personal interviews, which were scored as unsatisfactory, questionable, reliable, or high quality by the interviewers. Eight percent of the interviews were unsatisfactory or questionable. Increasing age, lower socioeconomic status, and poorer self-perceived health led to higher proportions of questionable or unreliable interviews. The odds ratio for cigarette smoking, the main risk factor for bladder cancer, was 6.18 (95% confidence interval: 4.56, 8.39) overall, 3.20 (95% confidence interval: 1.13, 9.04) among unsatisfactory or questionable interviews, 6.86 (95% confidence interval: 4.80, 9.82) among reliable interviews, and 7.70 (95% confidence interval: 3.64, 16.30) among high-quality interviews. Similar trends were observed for employment in high-risk occupations, drinking water containing elevated levels of trihalomethanes, and use of analgesics. Higher quality interviews led to stronger associations compared with risk estimation that did not take the quality of interview into account. The collection of quality of interview scores and the exclusion of unreliable interviews probably reduce misclassification of exposure in observational studies.

The LNA bound to beta-actin was then stained using phycoerythrin-conjugated streptavidin and detected by flow cytometry. Shifts in fluorescence signal intensity between the beta-actin LNA probe and a biotinylated, nonspecific control LNA were used to determine optimal conditions for this type of flow-FISH. Multiple conditions for permeabilization and hybridization were tested. and it was found that conditions using 3 mu g/ml of proteinase K for permeabilization and 90 min hybridization at 60 degrees C with buffer containing 50% formamide allow cells containing the LNA-bound mRNA to be detected and differentiated from the control LNA with high confidence (< 14% overlap between Curves). This combined method, called LNA flow-FISH, can be used for detection and quantification of other RNA species as well as for telomerase measurement and detection. (C) 2009 Elsevier Inc.

In cultured cells, it causes microtubule bundle formation, like those caused by paclitaxel. With tubulin, (-)-rhazinilam causes formation of an aberrant spiral polymer. Using glutamate and GTP, we developed an assay for spiral formation and applied it to 17 new (+/-)-rhazinilam analogs with either a modified side chain or a different size D ring. There was reasonable correlation between spiral formation and inhibition of human MCF-7 breast carcinoma cell growth. Only one side chain analog was as active as (+/-)-rhazinilam. During these studies, we observed that omitting GTP from the reaction mixture caused a major change in the morphology of the (-)-rhazinilam-induced polymer, with half the observed polymer being microtubule-like and half being spirals. This mixed polymer slowly disassembled at 0 degrees C, but there was no apparent difference in the lability of the microtubules versus the spirals. Published by Elsevier Inc.

To improve prognostic ability in ankylosing spondylitis (AS), we sought to identify demographic, clinical, and immunogenetic characteristics associated with radiographic severity in a large cohort of patients. Methods. Patients with AS for >= 20 years were enrolled in a cross-sectional study (n = 398). Pelvic and spinal radiographs were scored using the Bath Ankylosing Spondylitis Radiology Index for the spine (BASRI-s), and radiographic severity was measured as the BASRI-s/duration of AS. Clinical factors and HLA-B, DR, DQ, and DP alleles associated with the highest quartile of the distribution of radiographic severity were identified by first using random forests and then using multivariable logistic regression modeling. Similar procedures were used to identify factors associated with the lowest quartile of radiographic severity. Results. Radiographic severity (being in the top quartile of BASRI-s/duration of AS) was associated with older age at onset of AS (odds ratio [OR] 1.10 per year), male sex (OR 1.90), current smoker (OR 4.72), and the presence of HLA-B*4100 (OR 11.73), DRB1*0804 (OR 12.32), DQA1*0401 (OR 5.24), DQB1*0603 (OR 3.42), and DPB1*0202 (OR 23.36), whereas the presence of DRB1*0801 was strongly negatively associated (OR 0.03). Being in the lowest quartile of BASRI-s/duration of AS was also less likely among those with an older age at onset of AS (OR 0.94 per year), men (OR 0.281, and current smokers (OR 0.29). Conclusion. The accuracy of the prognosis of radiographic severity in AS is improved by knowing the age at disease onset, sex, smoking history, and the presence of HLA-B*4100, DRB1*0804, DQA1*0401, DQB1*0603, DRB1*0801, and DPB1*0202 alleles.

Neurodegeneration is often observed in humans, because of mechanical injuries (e.g., traumatic brain injury [TBI]) and ischemic damage (strokes). In this review, we discuss recent findings documenting the fact that the psychostimulant drug METH can cause neuronal damage in several brain regions. The accumulated evidence from our laboratories and those of other investigators indicates that acute administration of METH leads to activation of calpain and caspase proteolytic systems. These systems are also involved in causing neuronal damage secondary to traumatic and ischemic brain injuries. Protease activation is accompanied by proteolysis of endogenous neuronal structural proteins (all-spectrin protein and microtubule-associated protein-tau), evidenced by the appearance of their breakdown products after these injuries. When taken together, these observations suggest that METH exposure, like TBI, can cause substantial damage to the brain by causing both apoptotic and necrotic cell death in the brains of METH addicts who use large doses of the drug during their lifetimes. Finally, because METH abuse is accompanied by functional and structural changes in the brain similar to those in TBI, METH addicts might experience greater benefit if their treatment involved greater emphasis on rehabilitation in conjunction with potential neuroprotective pharmacological agents such as calpain and caspase inhibitors similar to those used in TBI.

Here, we studied the role of glial cell line-derived neurotrophic factor (GDNF) in incubation of cocaine craving because, like BDNF, GDNF provides trophic support to midbrain dopamine neurons. Methods: We first trained rats to self-administer intravenous cocaine for 10 days (6 hours/d, cocaine injections were paired with a tone-light cue). We then manipulated VTA GDNF function and assessed cue-induced cocaine seeking in extinction tests after withdrawal from cocaine. Results: VTA injections of an adeno-associated virus (AAV) vector containing rat GDNF cDNA (5 x 10(8) viral genomes) on withdrawal Day 1 increased cue-induced cocaine seeking on withdrawal days 1 land 31; this effect was not observed after VTA injections of an AAV viral vector containing red fluorescent protein (RFP). Additionally, VTA, but not substantial nigra (SN), GDNF injections (1.25 mu g or 12.5 mu g/side) immediately after the last cocaine self-ad ministration session increased cue-induced drug seeking on withdrawal days 3 and 10; this effect was reversed by VTA injections of U0126, which inhibits the activity of extracellular signal-regulated kinases (ERK). Finally, interfering with VTA GDNF function by chronic delivery of anti-GDNF monoclonal neutralizing antibodies via minipumps (600 ng/side/d) during withdrawal Days 1-14 prevented the time-dependent increases in cue-induced cocaine seeking on withdrawal days 11 and 31. Conclusions: Our results indicate that during the first weeks of withdrawal from cocaine self-administration, GDNF-dependent neuroadaptations in midbrain VTA neurons play an important role in the development of incubation of cocaine craving.

TI Enhanced Choice for Viewing Cocaine Pictures in Cocaine Addiction SO BIOLOGICAL PSYCHIATRY LA English DT Article DE Choice behavior; cocaine addiction; craving; IAPS pictures reward; neuropsychology; salience; unconscious motivation ID DOPAMINE D2 RECEPTORS; NEUROANATOMICAL SPECIFICITY; ATTENTIONAL BIAS; MONETARY REWARD; RHESUS-MONKEYS; USERS; FOOD; STRESS; CUES; REINFORCEMENT AB Background: Individuals with cocaine use disorder (CUD) chose cocaine over nondrug rewards. in two newly designed laboratory tasks with pictures, we document this modified choice outside of a cocaine administration paradigm. Methods: Choice for viewing cocaine, pleasant, unpleasant, or neutral pictures-under explicit contingencies (choice made between two fully visible side-by-side images) and under more implicit contingencies (selections made between pictures hidden under flipped-over cards)-was examined in 20 CUD and 20 matched healthy control subjects. Subjects also provided self-reported ratings of each picture's pleasantness and arousal. Results: Under both contingencies, CUD subjects chose to view more cocaine pictures than control subjects, group differences that were not fully explained by the self-reported picture ratings. Furthermore, whereas CUD subjects' choice for viewing cocaine pictures exceeded choice for viewing unpleasant pictures (but did not exceed choice for viewing pleasant pictures, in contrast to their self-reported ratings), healthy control subjects avoided viewing cocaine pictures as frequently as, or even more than, unpleasant pictures. Finally, CUD subjects with the most cocaine viewing selections, even when directly compared with selections of the pleasant pictures, also reported the most frequent recent cocaine use. Conclusions: Enhanced drug-related choice in cocaine addiction can be demonstrated even for nonpharmacologic (pictorial) stimuli. This choice, which is modulated by alternative stimuli, partly transcends self-reports (possibly indicative of a disconnect in cocaine addiction between self-reports and objective behavior) to provide an objective marker of addiction severity. Neuroimaging studies are needed to establish the neural underpinnings of such enhanced cocaine-related choice. C1 [Moeller, Scott J.] Univ Michigan, Dept Psychol, Ann Arbor, MI 48109 USA.

Several small molecules protect RAW264.7 macrophages and CHO cells from anthrax lethal toxin and protected cells from an LF-Pseudomonas exotoxin fusion protein and diphtheria toxin. Further efforts demonstrated that these compounds impaired the PA heptamer pre-pore to pore conversion in cells expressing the CMG2 receptor, but not the related TEM8 receptor, indicating that these compounds likely interfere with toxin internalization.

We have determined that the glucose moiety of 1 is the most structurally permissive region for designing analogues of this P2Y(14) agonist. For example, the carboxylate group of uridine-5'-diphosphoglucuronic acid proved to be suitable for flexible substitution by chain extension through an amide linkage. Functionalized congeners containing terminal 2-acylaminoethylamides prepared by this strategy retained P2Y(14) activity, and molecular modeling predicted close proximity of this chain to the second extracellular loop of the receptor. In addition, replacement of glucose with other sugars did not diminish P2Y(14) potency. For example, the [500] ribose derivative had an EC50 of 0.24 mu M. Selective monofluorination of the glucose moiety indicated a role for the 2 ''- and 6 ''- hydroxyl groups of 1 in receptor recognition. The beta-glucoside was twofold less potent than the native alpha-isomer, but methylene replacement of the 1 ''-oxygen abolished activity. Replacement of the ribose ring system with cyclopentyl or rigid bicyclo[3.1.0] hexane groups abolished activity. Uridine-5'-diphosphoglucose also activates the P2Y(2) receptor, but the 2-thio analogue and several of the potent modified-glucose analogues were P2Y(14)-selective. (C) 2009 Elsevier Ltd.

We show that introduction of the chiral center is uniformly deleterious to binding, with the (R)-enantiomer being more deleterious than the (S)enantiomer. A greater enantiomeric difference in potency is shown by inhibitors that have restricted rotation of the aryl ring, with the larger difference being due to poorer potency of the (R)-enantiomer rather than higher potency of the (S)-enantiomer. The potency difference for enantiomers based on the isoindoline-1,3-dione ring system is less than for those derived from the isoindol-1-one ring system. Our findings provide useful information that should aid in understanding molecular binding interactions of DKA-derived IN inhibitors. Published by Elsevier Ltd.

They also support marker assisted breeding and EST mapping. The problem of building a high quality physical map is computationally challenging due to unavoidable noise in the input fingerprint data. Results: We propose a novel compartmentalized method for the assembly of high quality physical maps from fingerprinted clones. The knowledge of genetic markers enables us to group clones into clusters so that clones in the same cluster are more likely to overlap. For each cluster of clones, a local physical map is first constructed using FingerPrinted Contigs (FPC). Then, all the individual maps are carefully merged into the final physical map. Experimental results on the genomes of rice and barley demonstrate that the compartmentalized assembly produces significantly more accurate maps, and that it can detect and isolate clones that would induce "chimeric" contigs if used in the final assembly.

TI Overexpression of DPAGT1 Leads to Aberrant N-Glycosylation of E-Cadherin and Cellular Discohesion in Oral Cancer SO CANCER RESEARCH LA English DT Article ID LYMPH-NODE METASTASIS; ALPHA-CATENIN; TIGHT JUNCTIONS; BETA-CATENIN; INVERSE CORRELATION; ADHESION; EXPRESSION; COMPLEX; MORPHOGENESIS; INVASIVENESS AB Cancer cells are frequently characterized by aberrant increases in protein N-glycosylation and by disruption of E-cadherin-mediated adherens junctions. The relationship between altered N-glycosylation and loss of E-cadherin adhesion in cancer, however, remains unclear. Previously, we reported that complex N-glycans on the extracellular domains of E-cadherin inhibited the formation of mature adherens junctions. Here, we examined whether dysregulated N-glycosylation was one of the underlying causes for cellular discohesion in oral cancer. We show that dense cultures of human salivary epidermoid carcinoma A253 cells exhibited elevated expression of DPAGT1, the gene that initiates protein N-glycosylation. Overexpression of DPAGT1 correlated with the production of E-cadherin-bearing complex N-glycans in nascent adherens junctions. Partial inhibition of DPAGT1 with small interfering RNA reduced the complex N-glycans of E-cadherin and increased the abundance of alpha-catenin and stabilizing proteins in adherens junctions. This was associated with the assembly of functional tight junctions. The inverse relationship between DPAGT1 expression and intercellular adhesion was a feature of oral squamous cell carcinoma. Oral squamous cell carcinomas displayed overexpression of DPAGT1 that correlated with diminished localization of E-cadherin and alpha-catenin at the sites of adherens junctions. Our studies show for the first time that DPAGT1 is an upstream regulator of E-cadherin N-glycosylation status and adherens junction composition and suggest that dysregulation of DPAGT1 causes disturbances in intercellular adhesion in oral cancer.

To characterize genomic instability in esophageal squamous cell carcinoma (ESCC), we examined loss of heterozygosity (LOH), copy number (CN) loss, CN gain, and gene expression using the Affymetrix GeneChip Human Mapping 500K (n = 30 cases) and Human U133A (n = 17 cases) arrays in ESCC cases from a high-risk region of China. We found that genomic instability measures varied widely among cases and separated them into two groups: a high-frequency instability group (two-thirds of all cases with one or more instability category of >= 10%) and a low-frequency instability group (one-third of cases with instability of <10%). Genomic instability also varied widely across chromosomal arms, with the highest frequency of LOH on 9p (33% of informative single nucleotide polymorphisms), CN loss on 3p (33%), and CN gain on 3q (48%). Twenty-two LOH regions were identified: four on 9p, seven on 9q, four on 13q, two on 17p, and five on 17q. Three CN loss regions-3p12.3, 4p15.1, and 9p21.3-were detected. Twelve CN gain regions were found, including six on 3q, one on 7q, four on 8q, and one on 11q. One of the most gene-rich of these CN gain regions was 11q13.1-13.4, where 26 genes also had RNA expression data available. CN gain was significantly correlated with increased RNA expression in over 80% of these genes. Our findings show the potential utility of combining CN analysis and gene expression data to identify genes involved in esophageal carcinogenesis.

TI Progressive Tumor Formation in Mice with Conditional Deletion of TGF-beta Signaling in Head and Neck Epithelia Is Associated with Activation of the PI3K/Akt Pathway SO CANCER RESEARCH LA English DT Article ID GROWTH-FACTOR-BETA; SQUAMOUS-CELL CARCINOMA; COLON-CANCER; I RECEPTOR; T-CELLS; ANGIOGENESIS; PROMOTES; CARCINOGENESIS; MUTATIONS; TUMORIGENESIS AB The precise role of transforming growth factor (TGF)-beta signaling in head and neck squamous cell carcinoma (SCC) is not yet fully understood. Here, we report generation of an inducible head- and neck-specific knockout mouse model by crossing TGF-beta receptor 1 (Tgfbr1) floxed mice with K14-CreER(lam) mice. By applying tamoxifen to oral cavity of the mouse to induce Cre expression, we were able to conditionally delete Tgfbr1 in the mouse head and neck epithelia. on tumor induction with 7,12-dimethylbenz(a)anthracene (DMBA), 45% of Tgfbr1 conditional knockout (cKO) mice (n = 42) developed SCCs in the head and neck area starting from 16 weeks after treatment. However, no tumors were observed in the control littermates. A molecular analysis revealed an enhanced proliferation and loss of apoptosis in the basal layer of the head and neck epithelia of Tgfbr1 cKO mice 4 weeks after tamoxifen and DMBA treatment. The most notable finding of our study is that the phosphoinositide 3-kinase (PI3K)/Akt pathway was activated in SCCs that developed in the Tgfbr1 cKO mice on inactivation of TGF-beta signaling through Smad2/3 and DMBA treatment. These observations suggest that activation of Smad-independent pathways may contribute cooperatively with inactivation of Smad-dependent pathways to promote head and neck carcinogenesis in these mice. Our results revealed the critical role of the TGF-beta signaling pathway and its crosstalk with the PI3K/Akt pathway in suppressing head and neck carcinogenesis.

More needs to be learned about mechanisms that control this process. In particular, the role of chemokine receptors in metastasis remains controversial. Here, using a highly metastatic breast cancer (4T1) model, we show that lung metastasis is a feature of only a proportion of the tumor cells that express CCR4. Moreover, the primary tumor growing in mammary pads activates remotely the expression of TARC/CCL17 and MDC/CCL22 in the lungs. These chemokines acting through CCR4 attract both tumor and immune cells. However, CCR4-mediated chemotaxis was not sufficient to produce metastasis, as tumor cells in the lung were efficiently eliminated by natural killer (NK) cells. Lung metastasis required CCR4(+) regulatory T cells (Treg), which directly killed NK cells using beta-galactoside-binding protein. Thus, strategies that abrogate any part of this process should improve the outcome through activation of effector cells and prevention of tumor cell migration. We confirm this prediction by killing CCR4(+) cells through delivery of TARC-fused toxins or depleting Tregs and preventing lung metastasis.

Research interest in the entity responsible for this phenomenon, the 'mitochondrial permeability transition pore' (mPTP), has dramatically increased after demonstration that it plays a key role in the life and death decision in cells. Therefore, a better understanding of this phenomenon and its regulation by environmental stresses, kinase signalling, and pharmacological intervention is vital. The characterization of the molecular identity of the mPTP will allow identification of possible pharmacological targets and assist in drug design for its precise regulation. However, despite extensive research efforts, at this point the pore-forming core component(s) of the mPTP remain unidentified. Pivotal new genetic evidence has shown that components once believed to be core elements of the mPTP (namely mitochondrial adenine nucleotide translocator and cyclophilin D) are instead only mPTP regulators (or in the case of voltage-dependent anion channels, probably entirely dispensable). This review provides an update on the current state of knowledge regarding the regulation of the mPTP. C1 [Zorov, Dmitry B.; Juhaszova, Magdalena; Yaniv, Yael; Nuss, H.

Isolated mouse hearts were perfused in the Langendorff mode and subjected to global no-flow ischaemia followed by reperfusion. Hearts were analysed for recovery of left ventricular developed pressure (LVDP), mRNA levels, and protein expression. Naive hearts from sEH null mice had similar expression of preproBNP (Nppb) mRNA compared with wild-type (WT) hearts. However, significant increases in Nppb mRNA and BNP protein expression occurred during post-ischaemic reperfusion and correlated with improved post-ischaemic recovery of LVDP. Perfusion with the putative EET receptor antagonist 14,15-epoxyeicosa-5(Z)-enoic acid prior to ischaemia reduced the preproBNP mRNA in sEH null hearts. Inhibitor studies demonstrated that perfusion with the natriuretic peptide receptor type-A (NPR-A) antagonist, A71915, limited the improved recovery in recombinant full-length mouse BNP (rBNP)- and 11,12-EET-perfused hearts as well as in sEH null mice. Increased expression of phosphorylated protein kinase C epsilon and Akt were found in WT hearts perfused with either 11,12-EET or rBNP, while mitochondrial glycogen synthase kinase-3 beta was significantly lower in the same samples. Furthermore, treatment with the phosphoinositide 3-kinase (PI3K) inhibitor wortmannin abolished improved LVDP recovery in 11,12-EET-treated hearts but not did significantly inhibit recovery of rBNP-treated hearts. Taken together, these data indicate that EET-mediated cardioprotection involves BNP and PI3K signalling events.

The signals are conveyed by way of a complex network of molecular interactions. To clarify those complexities, we have constructed a molecular interaction map (MIM) using a novel hierarchical assembly procedure. Molecules were arranged on the map in hierarchical levels according to interaction step distance from the DNA region of stalled replication. The hierarchical MIM allows us to disentangle the network's interlocking pathways and loops and to suggest functionally significant features of network architecture. The MIM shows how parallel pathways and multiple feedback loops can provide failsafe and robust switch-like responses to replication stress. Within the central level of hierarchy ATR and Claspin together appear to function as a nexus that conveys signals from many sources to many destinations. We noted a division of labor between those two molecules, separating enzymatic and structural roles. In addition, the network architecture disclosed by the hierarchical map, suggested a speculative model for how molecular crowding and the granular localization of network components in the cell nucleus can facilitate function.

TI Prevention of Radiation-Induced Oral Mucositis after Adenoviral Vector - Mediated Transfer of the Keratinocyte Growth Factor cDNA to Mouse Submandibular Glands SO CLINICAL CANCER RESEARCH LA English DT Article ID TRANSGENIC SECRETORY PROTEINS; GENE-TRANSFER; SALIVARY-GLANDS; NECK-CANCER; EPITHELIAL-CELLS; PAROTID-GLANDS; LUNG INJURY; CHEMOTHERAPY; HEAD; RADIOTHERAPY AB Purpose: The study aims to evaluate if human keratinocyte growth factor (hKGF), secreted after transduction of murine salivary glands with adenoviral vectors, can prevent oral mucositis resulting from radiation. Experimental Design: Two serotype 5 adenoviral vectors encoding hKGF were constructed: AdEF1 alpha-hKGF and AdLTR(2)EF1 alpha-hKGF. Female C3H mice, 8 weeks old, were irradiated by single (22.5 Gy) or fractionated (5 x 8 Gy for 5 days) doses to induce oral mucositis (ulcers on tongue). One day before irradiation, the above viral vectors or an empty vector, Adcontrol, was given (10(10) particles per gland) to both submandibular glands by retrograde ductal instillation. Each experiment included five groups: no irradiation and irradiation (+/-Adcontrol, AdEF1 alpha-hKGF, or AdLTR(2)EF1 alpha-hKGF). Blood, saliva, submandibular glands, and tongue were collected on day 7 for single-dose studies or day 10 for fractionated dosing. hKGF levels were measured by ELISA. Results: In three separate single-dose irradiation experiments, lingual ulcers were dramatically reduced after either KGF-expressing vector. Similarly, in two separate fractionated irradiation experiments, the hKGF-expressing vectors completely prevented ulcer formation. QPCR data indicated that similar to 10(7) to 10(8) particles of each vector remained in the targeted submandibular glands at the terminal time. Transgenic hKGF protein was found at high levels in saliva, serum, and submandibular gland extracts. Conclusions: hKGF gene transfer to salivary glands prevented radiation-induced oral mucositis in mice. This proof of concept study suggests that transgenic hKGF secreted from transduced salivary glands maybe useful clinically to prevent oral mucositis caused by radiation.

Here, we show that this gene-density correlated CT positioning holds for the most gene-rich and gene-poor bovine chromosomes 19 and 20, respectively, in bovine fibroblast and lymphocyte nuclei. In order to determine the period at which this non-random CT order is established during development, we performed fluorescence in Situ hybridization, on three-dimensionally preserved bovine preimplantation embryos generated by in vitro fertilization and investigated the distribution of BTA 19 and 20 CTs. Radial arrangements of CTs 19 and 20 were the same up to the 8-cell stage. At the 10- to 16-cell stage, however, a significant difference became apparent with CTs 19 localized more internally and CTs 20 more peripherally. Since major genome activation in bovine embryos occurs at the 8- to 16-cell stage, our findings demonstrate a temporal correlation between transcriptional activation and a major rearrangement of chromatin topography in blastomere nuclei.

Here we determined the order of events during myofibril assembly through time-lapse confocal microscopy of cultured embryonic chick cardiomyocytes coexpressing fluorescently tagged N-RAP and either alpha-actinin or actin. During de novo myofibril assembly, N-RAP assembled in fibrillar structures within the cell, with dots of alpha-actinin subsequently organizing along these structures. The initial fibrillar structures were reminiscent of actin fibrils, and coassembly of N-RAP and actin into newly formed fibrils supported this. The alpha-actinin dots subsequently broadened to Z-Iines that were wider than the underlying N-RAP fibril, and N-RAP fluorescence intensity decreased. FRAP experiments showed that most of the alpha-actinin dynamically exchanged during all stages of myofibril assembly. In contrast, less than 20% of the N-RAP in premyofibrils was exchanged during 10-20 min after photobleaching, but this value increased to 70% during myofibril maturation. The results show that N-RAP assembles into an actin containing scaffold before alpha-actinin recruitment; that the N-RAP scaffold is much more stable than the assembling structural components; that N-RAP dynamics increase as assembly progresses; and that N-RAP leaves the structure after assembly is complete.

Here, the one-electron oxidation of (bi)sulfite catalyzed by horseradish peroxidase/H(2)O(2) has been reinvestigated by ESR spin trapping with DMPO and oxygen uptake studies to obtain further evidence for the radical reaction mechanism. In the case of ESR experiments, the signal of the DMPO/(center dot)SO(3)(-) radical adduct was detected, and the initial rate of its formation was calculated. Support for the radical pathway via (center dot)SO(3)(-) was obtained from the stoichiometry between the amount of consumed molecular oxygen and the amount of (bi)sulfite oxidized to sulfate (SO(4)(2-)). When DMPO was incubated with (bi)sulfite, oxygen consumption was completely inhibited owing to the efficiency of DMPO trapping. In the absence of DMPO, the initial rate of oxygen and H(2)O(2) consumption was determined to be half of the initial rate of DMPO/(center dot)SO(3)(-) radical adduct formation as determined by ESR, demonstrating that DMPO forms the radical adduct by trapping the (center dot)SO(3)(-) exclusively. We conclude that DMPO is not susceptible to artifacts arising from nonradical chemistry (nucleophilic addition) except when both (bi)sulfite and DMPO concentrations are at nonphysiological levels of at least 0.1 M and the incubations are for longer times.

TI Genome-wide association meta-analysis for total serum bilirubin levels SO HUMAN MOLECULAR GENETICS LA English DT Article ID CORONARY-HEART-DISEASE; ORGANIC CATION TRANSPORTER; UGT1A1-ASTERISK-28 ALLELE; OATP-C; GENE; POLYMORPHISMS; EXPRESSION; INHERITANCE; ROTTERDAM; DESIGN AB Variation in serum bilirubin is associated with altered cardiovascular disease risk and drug metabolism. We aimed to identify genetic contributors to variability in serum bilirubin levels by combining results from three genome-wide association studies (Framingham heart study, n = 3424; Rotterdam study, n = 3847; Age, Gene, Environment and Susceptibility-Reykjavik, n = 2193). Meta-analysis showed strong replication for a genetic influence on serum bilirubin levels of the UGT1A1 locus (P < 5 x 10(-324)) and a 12p12.2 locus. The peak signal in the 12p12.2 region was a non-synonymous SNP in SLCO1B1 (rs4149056, P = 6.7 x 10(-13)), which gives rise to a valine to alanine amino acid change leading to reduced activity for a hepatic transporter with known affinity for bilirubin. There were also suggestive associations with several other loci. The top variants in UGT1A1 and SLCO1B1 explain similar to 18.0 and similar to 1.0% of the variation in total serum bilirubin levels, respectively. In a conditional analysis adjusted for individual genotypes for the top UGT1A1 variant, the top SLCO1B1 variant remained highly significant (P = 7.3 x 10(-13)), but no other variants achieved genome-wide significance. In one of the largest genetic studies of bilirubin to date (n = 9464), we confirm the substantial genetic influence of UGT1A1 variants, consistent with past linkage and association studies, and additionally provide strong evidence of a role for allelic variation in SLCO1B1. Given the involvement of bilirubin in a number of physiological and disease processes, and the roles for UGT1A1 and SLCO1B1 in drug metabolism, these genetic findings have potential clinical importance. In analyses for association with gallbladder disease or gallstones, top bilirubin SNPs in UGT1A1 and SLCO1B1 were not associated.

Unconjugated bilirubin is transported into hepatocytes. There, it is glucuronidated by UGT1A1 and secreted into the bile canaliculi. We report a genome wide association scan in 4300 Sardinian individuals for total serum bilirubin levels. In addition to the two known loci previously involved in the regulation of bilirubin levels, UGT1A1 (P = 6.2 x 10(-62)) and G6PD (P = 2.5 x 10(-8)), we observed a strong association on chromosome 12 within the SLCO1B3 gene (P = 3.9 x 10(-9)). Our findings were replicated in an independent sample of 1860 Sardinians and in 832 subjects from the Old Order Amish (combined P < 5 x 10(-14)). We also show that SLC01B3 variants contribute to idiopathic mild unconjugated hyperbilirubinemia. Thus, SLC01B3 appears to be involved in the regulation of serum bilirubin levels in healthy individuals and in some bilirubin-related disorders that are only partially explained by other known gene variants.

Cichon, Sven TI The DISC locus and schizophrenia: evidence from an association study in a central European sample and from a meta-analysis across different European populations SO HUMAN MOLECULAR GENETICS LA English DT Article ID MULTILOCUS GENOTYPE DATA; MAJOR MENTAL-ILLNESS; BIPOLAR DISORDER; GENES; TRANSLOCATION; INFERENCE; GENETICS; LINKAGE; GENOME; RISK AB Association studies, as well as the initial translocation family study, identified the gene Disrupted-In-Schizophrenia-1 (DISC1) as a risk factor for schizophrenia. DISC1 encodes a multifunctional scaffold protein involved in neurodevelopmental processes implicated in the etiology of schizophrenia. The present study explores the contribution of the DISC locus to schizophrenia using three different approaches: (i) systematic association mapping aimed at detecting DISC risk variants in a schizophrenia sample from a central European population (556 SNPs, n = 1621 individuals). In this homogenous sample, a circumscribed DISC1 interval in intron 9 was significantly associated with schizophrenia in females (P = 4 x 10(-5)) and contributed most strongly to early-onset cases (P = 9 x 10(-5)). The odds ratios (ORs) were in the range of 1.46-1.88. (ii) The same sample was used to test for the locus-specific SNP-SNP interaction most recently associated with schizophrenia. Our results confirm the SNP interplay effect between rs1538979 and rs821633 that significantly conferred disease risk in male patients with schizophrenia (P = 0.016, OR 1.57). (iii) In order to detect additional schizophrenia variants, a meta-analysis was performed using nine schizophrenia samples from different European populations (50 SNPs, n = 10 064 individuals maximum, n = 3694 minimum). We found evidence for a common schizophrenia risk interval within DISC1 intron 4-6 (P = 0.002, OR 1.27). The findings point to a complex association between schizophrenia and DISC, including the presence of different risk loci and SNP interplay effects. Furthermore, our phenotype-genotype results-including the consideration of sex-specific effects-highlight the value of homogenous samples in mapping risk genes for schizophrenia in general, and at the DISC locus in particular.

Characterization of antibody responses to salivary antigens offers the potential to develop immunologically based monitoring techniques for exposure to re-emergent triatomine bug populations in peridomestic animals. IgG-antibody responses to the salivary antigens of T. infestans have been detected in chickens as soon as 2 days after the first exposure to five adult bugs. Chickens and guinea pigs regularly exposed to this number of triatomines showed a significantly lower anti-saliva antibody titre than animals exposed to 25 adults and fifth instars of four different T. infestans strains originating from Bolivia and from Northern Chile. Highly immunogenic salivary antigens of 14 and 21 kDa were recognised by all chicken sera and of 79 kDa by all guinea pig sera. Cross-reactivity studies using saliva or salivary gland extracts from different hematophagous species, e.g. different triatomines, bed bugs, mosquitoes, sand flies and ticks, as well as chicken sera exposed to triatomines and mosquitoes, demonstrated that the 14 and 21 kDa salivary antigens were only found in triatomines. Sera from peridomestic chickens and guinea pigs in sites of known T. infestans challenge in Bolivia also recognised the 14 and 21 kDa antigens. These represent promising epidemiological markers for the detection of small numbers of feeding bugs and hence may be a new tool for vector surveillance in Chagas disease control programs.

From the U.S. Surveillance Epidemiology and End Results-Medicare database, we selected 44,350 lymphoid malignancy cases (>= 67 years) and 122,531 population-based controls. Logistic regression was used to derive odds ratios (ORs) comparing the prevalence of autoimmune conditions in cases and controls, by lymphoid malignancy subtype, adjusted for gender, age at malignancy/selection, year of malignancy/selection, race and number of physician claims. The strongest associations observed by non-Hodgkin lymphoma (NHL) subtypes were diffuse large B-cell lymphoma with rheumatoid arthritis (OR 1.4, 95% CI 1.2-1.5) and Sjogren syndrome (2.0, 1.5-2.8); T-cell lymphoma with hemolytic anemia (9.7, 4.3-22), psoriasis (3.1, 2.5-4.0), discoid lupus erythematosus (4.4, 2.3-8.4) and celiac disease (5.0, 2.4-14); and marginal zone lymphoma with Sjogren syndrome (6.6, 4.6-9.5), systemic lupus erythematosus (2.8, 1.7-4.7) and hemolytic anemia (7.4, 3.1-18). Hodgkin lymphoma was associated with systemic lupus erythematosus (3.5, 1.9-6.7). Multiple myeloma was associated only with pernicious anemia (1.5, 1.3-1.7). Several autoimmune conditions were associated with increased risk of lymphoid neoplasms, especially NHLs of diffuse large B-cell, marginal zone and T-cell subtypes. These results support a mechanism whereby chronic antigenic stimulation leads to lymphoid malignancy. Published 2009 UICC.

Patients and Methods: Between 1995 and 1999, 35 patients with nonmetastatic, Stage III or IV squamous cell carcinoma of the head and neck were treated with three cycles of paclitaxel as a 120-h continuous infusion beginning on Days 1, 21, and 42, concurrent with radiotherapy. The initial 16 patients received 105 mg/m(2)/cycle, and the subsequent 19 patients received 120 mg/m(2)/cycle. External beam radiotherapy was delivered to a dose of 70.2-72 Gy at five fractions weekly. Patients were followed to evaluate the disease outcomes and late toxicity of this regimen. Results: The median follow-up for all patients was 56.5 months. The median survival was 56.5 months, and the median time to local recurrence was not reached. Of the 35 patients, 15 (43%) developed hypothyroidism. Of the 33 patients who underwent percutaneous endoscopic gastrostomy tube placement, 11 were percutaneous endoscopic gastrostomy tube dependent until death or their last follow-up visit. Also, 5 patients (14%) required a tracheostomy until death, and 3 (9%) developed a severe esophageal stricture. All evaluated long-term survivors exhibited salivary hypofunction. Fibrosis in the radiation field occurred in 24 patients (69%). Conclusion: The results of our study have shown that concurrent chemoradiotherapy with a 120-h infusion of paclitaxel provides long-term local control and survival in patients with squamous cell carcinoma of the head and neck. Xerostomia, hypothyroidism, esophageal and pharyngeal complications, and subcutaneous fibrosis were common long-term toxicities; however, the vast majority of toxicities were grade 1 or 2.

As a result, the number of patients living with long-term toxic effects due to HSCT has increased. A once rare condition of the donor immune cells attacking healthy host tissues, termed chronic graft-vs-host disease, has become a more common phenomenon. When chronic graft-vs-host disease affects the lung tissue, bronchiolitis obliterans syndrome ensues. Recent data suggest that bronchiolitis obliterans syndrome may affect up to 6% of HSCT recipients and dramatically alters survival, with overall survival of only 13% at 5 years. These statistics have not improved since the first presentation of this disease over 20 years ago. Challenges to the progress of medical management of bronchiolitis obliterans syndrome include difficulties and delays in diagnosis and a paucity of data on pathogenesis to direct new therapies. This article critically evaluates the current diagnostic criteria for bronchiolitis obliterans syndrome and reviews the epidemiology, pathogenesis, and available treatments. Improvements in survival will likely require early disease recognition, allowing for therapeutic modulation of disease prior to the development of irreversible airway obliteration.

Negative autoregulation has been shown to reduce cell-cell variation in regulatory protein levels and speed up the response time in gene networks. In this work we examined transcription regulation of the galS gene and the function of its product, the GalS protein. We observed a unique operator preference of the GalS protein characterized by dominant negative autoregulation. We show that this pattern of regulation limits the repression level of the target genes in steady states. We suggest that transcription factors with dominant negative autoregulation are designed for regulating gene expression during environmental transitions.

MSUC is initiated by the recruitment of the tumor suppressor protein BRCA1 to the axes of unsynapsed chromosomes. We now show that Sycp3, a structural component of the chromosome axis, is required for localization of BRCA1 to unsynapsed pachytene chromosomes. Importantly, we find that oocytes carrying an excess of two to three pairs of asynapsed homologous chromosomes fail to recruit enough BRCA1 to the asynapsed axes to activate MSUC. Furthermore, loss of MSUC function only transiently rescues oocytes from elimination during early postnatal development. The fact that the BRCA1-dependent synapsis surveillance system cannot respond to higher degrees of asynapsis and is dispensable for removal of aberrant oocytes argues that MSUC has a limited input as a quality control mechanism in female germ cells.

TI Patent Filarial Infection Modulates Malaria-Specific Type 1 Cytokine Responses in an IL-10-Dependent Manner in a Filaria/Malaria-Coinfected Population SO JOURNAL OF IMMUNOLOGY LA English DT Article ID PLASMODIUM-FALCIPARUM MALARIA; TUMOR-NECROSIS-FACTOR; HUMAN LYMPHATIC FILARIASIS; MURINE CEREBRAL MALARIA; SCHISTOSOMA-HAEMATOBIUM INFECTION; ASCARIS-LUMBRICOIDES INFECTION; BLOOD-STAGE MALARIA; IMMUNE-RESPONSES; T-CELLS; HELMINTH COINFECTION AB The effect of filarial infections on malaria-specific immune responses was investigated in Malian villages coendemic for filariasis (Fit) and malaria. Cytokines were measured from plasma and Ag-stimulated whole blood from individuals with Wuchereria bancrofti and/or Mansonella perstans infections (Fil(+); n = 19) and those without evidence of filarial infection (Fil(-); n = 19). Plasma levels of IL-10 (geometric mean [GM], 22.8 vs 10.4) were higher in Fil(+) compared with Fil(-), whereas levels of IFN-inducible protein (IP)-10 were lower in Fil(+) (GM, 66.3 vs 110.0). Fil(+) had higher levels of spontaneously secreted IL-10 (GM, 59.3 vs 6.8 pg/ml) and lower levels of IL-2 (1.0 vs 1.2 pg/ml) than did Fil(-). Although there were no differences in levels of Staphylococcus aureus enterotoxin B-induced cytokines between the two groups, Fil(+) mounted lower IL-12p70 (GM, 1.11 vs 3.83 pg/ml; p = 0.007), IFN-gamma (GM, 5.44 vs 23.41 pg/ml; p = 0.009), and IP-10 (GM, 29.43 vs 281.7 pg/ml; p = 0.007) responses following malaria Ag (MalAg) stimulation compared with Fil(-). In contrast, Fil(+) individuals had a higher MalAg-specific IL-10 response (GM, 7318 pg/ml vs 3029 pg/ml; p = 0.006) compared with those without filarial infection. Neutralizing Ab to IL-10 (but not to TGF beta) reversed the down-regulated MalAg-specific IFN-gamma and IP-10 (p < 0.001) responses in Fil(+). Together, these data demonstrate that filarial infections modulate the Plasmodium falciparum-specific IL-12p70/IFN-gamma secretion pathways known to play a key role in resistance to malaria and that they do so in an IL-10-dependent manner.

By using an in vivo model of CD3-specific Ab-induced flu-like syndrome, we show in this paper that a single injection of sublethal dose of the Ab killed all TGF-beta 1(-/-) Mice. The death of TGF-beta 1(-/-) mice was associated with occurrence of this uncontrolled flu-like syndrome, as demonstrated by a sustained storm of systemic inflammatory TNF and IFN-gamma cytokines. We present evidence that deficiency of professional phagocytes to produce TGF-beta 1 after apoptotic T cell clearance may be responsible, together with hypersensitivity of T cells to both activation and apoptosis, for the uncontrolled inflammation. These findings indicate a key role for TGF-beta 1 and phagocytes in protecting the recipients from lethal inflammation and resolving the flu-like syndrome after CD3-specific Ab treatment. The study may also provide a novel molecular mechanism explaining the early death in TGF-beta 1(-/-) mice. The Journal of Immunology, 2009, 183: 953-961.

Herein, we show that the positively charged residues of the BRS enable this region of CD3 to complex a subset of acidic phospholipids, including PI(3)P, PI(4)P, PI(5)P, PI(3,4,5)P(3), and PI(4,5)P(2). Transgenic mice containing mutations of the BRS exhibited varying developmental defects, ranging from reduced thymic cellularity to a complete block in T cell development. Peripheral T cells from BRS-modified mice also exhibited several defects, including decreased TCR surface expression, reduced TCR-mediated signaling responses to agonist peptide-loaded APCs, and delayed CD3 a localization to the immunological synapse. Overall, these findings demonstrate a functional role for the CD3 epsilon lipid-binding domain in T cell biology. The Journal of Immunology, 2009, 183: 1055-1064.

TI Differential Association of Programmed Death-1 and CD57 with Ex Vivo Survival of CD8(+) T Cells in HIV Infection SO JOURNAL OF IMMUNOLOGY LA English DT Article ID FAS-MEDIATED APOPTOSIS; DISEASE PROGRESSION; PD-1 EXPRESSION; CD95/FAS-INDUCED APOPTOSIS; VIRAL-INFECTION; ACTIVATION; RESPONSES; RECEPTOR; TRANSLOCATION; LYMPHOCYTES AB Recent studies have revealed the critical role of programmed death-1 (PD-1) in exhaustion of HIV- and SIV-specific CD8(+) T cells. In this study, we show that high expression of PD-1 correlates with increased ex vivo spontaneous and CD95/Fas-induced apoptosis, particularly in the "effector-memory" CD8(+) T cell population from HIV+ donors. High expression of PD-1 was linked to a proapoptotic phenotype characterized by low expression of Bcl-2 and IL7-R alpha, high expression of CD95/Fas and high mitochondrial mass. Expression of PD-1 and CD57 was differentially associated with the maturation status of CD8(+) T cells in HIV infection. CD57 was linked to higher apoptosis resistance, with cells expressing a PD-1(L)CD57(H) phenotype exhibiting lower levels of cell death. The majority of HIV-specific CD8(+) T cells were found to express a PD-1(H)CD57(L) or PD-1(H)CD57(H) phenotype. No correlation was found between PD-1 expression and ex vivo polyfunctionality of either HIV- or CMV-specific CD8(+) T cells. Contrary to CD57, high expression of PD-1 was characterized by translocation of PD-1 into the area of CD95/Fas-capping, an early necessary step of CD95/Fas-induced apoptosis. Thus, our data further support the role of PD-1 as a preapoptotic factor for CD8(+) T cells in HIV infection. The Journal of Immunology, 2009, 183: 1120-1132.

Although the pregnant uterine microenvironment is replete with innate immune cells and TLR expression, the mechanisms that facilitate adverse effects of their activation are largely unknown. In this study, we mimic the activation of TLR9 with its pathogenic ligand hypomethylated CpG and demonstrate that IL-10 proficiency protects against CpG-induced pregnancy complications. We show that fetal resorption and preterm birth are rapidly induced in IL-10(-/-) mice by low doses of CpG (similar to 25 mu g/mouse) when injected i.p. on gestational day 6 or gestational day 14, respectively. In contrast, wild-type mice failed to experience such effects at comparable doses, but pups born at term displayed craniofacial/limb defects in response to higher doses (similar to 400 mu g/mouse). Pregnancy complications in IL-10(-/-) mice were associated with unexpected and robust TLR9-triggered activation and amplification of uterine neutrophil and macrophage subpopulations followed by their migration to the placental zone. Furthermore, a dramatic increase in serum levels of mouse KC and TNF-alpha production by uterine F4/80(+) cells, but not uterine NK or Gr-1(+)CD11b(+) cells, was observed. Depletion of F4/80+ macrophages or neutralization of TNF-a rescued pregnancy to term. Our results have important implications for IL-10-mediated "uterine tolerance" against CpG-driven innate immune activation. The Journal of Immunology, 2009, 183: 1144-1154.

IL-10 controls proinflammatory cytokine and chemokine production indirectly via the transcription factor Stat3. One of the most physiologically significant IL-10 targets is TNF-alpha, a potent proinflammatory mediator that is the target for multiple anti-TNF-alpha clinical strategies in Crohn's disease and rheumatoid arthritis. The anti-inflammatory effects of IL-10 seem to be mediated by several incompletely understood transcriptional and posttranscriptional mechanisms. In this study, we show that in LPS-activated bone marrow-derived murine macrophages, IL-10 reduces the mRNA and protein levels of TNF-a and IL-1 alpha in part through the RNA destabilizing factor tristetraprolin (TTP). TTP is known for its central role in destabilizing mRNA molecules containing class II AU-rich elements in 3' untranslated regions. We found that IL-10 initiates a Stat3-dependent increase of TTP expression accompanied by a delayed decrease of p38 MAPK activity. The reduction of p38 MAPK activity releases TTP from the p38 MAPK-mediated inhibition, thereby resulting in diminished mRNA and protein levels of proinflammatory cytokines. These findings establish that TTP is required for full responses of bone marrow-derived murine macrophages to IL-10. The Journal of Immunology, 2009, 183: 1197-1206.

By analyzing the cellular responses to mycobacterial antigens in patients who had latent tuberculosis with or without filarial infection, we were able to demonstrate that filarial infection coincident with M. tuberculosis infection significantly diminishes M. tuberculosis-specific Th1 (interleukin [IL]-12 and IFN-gamma) and type 17 T helper (Th17; IL-23 and IL-17) responses related to increased expression of cytotoxic T lymphocyte antigen (CTLA)-4 and programmed death (PD)-1. Blockade of CTLA-4 restored production of both IFN-gamma and IL-17, whereas PD-1 blockade restored IFN-gamma production only. Thus, coincident filarial infection exerted a profound inhibitory effect on protective mycobacteria-specific Th1 and Th17 responses in latent tuberculosis, suggesting a mechanism by which concomitant filarial (and other systemic helminth) infections predispose to the development of active tuberculosis in humans.

Here we asked whether similar perceptual elongation can be observed in healthy participants after deprivation and, crucially, how soon after deprivation this elongation occurs. To answer this question, we patched one eye, thus noninvasively and reversibly depriving bottom-up input to the region of primary visual cortex (V1) corresponding to the blind spot (BS) in the unpatched eye, and tested whether and how quickly elongation occurs after the onset of deprivation. Within seconds of eye patching, participants perceived rectangles adjacent to the BS to be elongated toward the BS. We attribute this perceptual elongation to rapid receptive field expansion within the deprived V1 as reported in electrophysiological studies after retinal lesions and refer to it as "referred visual sensations" (RVS). This RVS is too fast to be the result of structural changes in the cortex (e. g., the growth of new connections), instead implicating unmasking of preexisting connections as the underlying neural mechanism. These findings may shed light on other reported perceptual distortions, as well as the phenomena of "filling-in."

Motoneuronal activity was recorded simultaneously from abdominal (AbN), phrenic (PN), hypoglossal (HN) and central vagus nerves from neonatal and juvenile rats in situ. During eupnoeic activity, low-amplitude post-inspiratory (post-I) discharge was only present in AbN motor outflow. Expression of AbN late-expiratory (late-E) activity, preceding PN bursts, occurred during hypercapnia. Biphasic expiratory (biphasic-E) activity with pre-inspiratory (pre-I) and post-I discharges occurred only during eucapnic anoxia or hypercapnic anoxia. Late-E activity generated during hypercapnia (7-10% CO2) was abolished with pontine transections or chemical suppression of retrotrapezoid nucleus/ventrolateral parafacial (RTN/vlPF). AbN late-E activity during hypercapnia is coupled with augmented pre-I discharge in HN, truncated PN burst, and was quiescent during inspiration. Our data suggest that the pons provides a necessary excitatory drive to an additional neural oscillatory mechanism that is only activated under conditions of high respiratory drive to generate late-E activity destined for AbN motoneurones. This mechanism may arise from neurons located in the RTN/vlPF or the latter may relay late-E activity generated elsewhere. We hypothesize that this oscillatory mechanism is not a necessary component of the respiratory central pattern generator but constitutes a defensive mechanism activated under critical metabolic conditions to provide forced expiration and reduced upper airway resistance simultaneously. Possible interactions of this oscillator with components of the brainstem respiratory network are discussed. C1 [Abdala, A. P. L.; Paton, J. F.

Accurate measurement of the very small RCSA from the difference in N-15 chemical shift under isotropic and weakly aligning liquid crystaltine conditions is very sensitive to minute differences in sample conditions, such as pH or ionic strength. For this reason, chemical shifts were measured for the same solution, under static liquid crystalline alignment, and under magic angle spinning conditions where alignment relative to the magnetic field is removed. Measurements were made for 14 well-resolved G-N-1 and 6 U-N-3 N-15 nuclei in a sample of tRNA(val). Fitting these RCSA data together with N-15-H-1 dipole-CSA cross-correlated relaxation measurements to the recently refined structural model of tRNA(val) yields the magnitude, asymmetry, and orientation of the N-15 CSA tensors C1 [Grishaev, Alexander; Yao, Lishan; Ying, Jinfa; Bax, Ad] NIDDK, Chem Phys Lab, NIH, Bethesda, MD 20892 USA.

TI Using the Experimentally Determined Components of the Overall Rotational Diffusion Tensor To Restrain Molecular Shape and Size in NMR Structure Determination of Globular Proteins and Protein-Protein Complexes SO JOURNAL OF THE AMERICAN CHEMICAL SOCIETY LA English DT Article ID N-TERMINAL DOMAIN; SMALL-ANGLE SCATTERING; MACROMOLECULAR STRUCTURE DETERMINATION; RESIDUAL DIPOLAR COUPLINGS; X-RAY-SCATTERING; ENZYME-I; PHOSPHOTRANSFERASE SYSTEM; STRUCTURE REFINEMENT; PHOSPHOCARRIER PROTEIN; 3-DIMENSIONAL STRUCTURES AB This paper describes an approach for making use of the components of the experimentally determined rotational diffusion tensor derived from NMR relaxation measurements in macomolecular structure determination. The parameters of the rotational diffusion tensor describe the shape and size of the macromolecule or macromolecular complex, and are therefore complementary to traditional NMR restraints. The structural information contained in the rotational diffusion tensor is not dissimilar to that present in the small-angle region of solution X-ray scattering profiles. We demonstrate the utility of rotational diffusion tensor restraints for protein structure refinement using the N-terminal domain of enzyme I (EIN) as an example and validate the results by solution small-angle X-ray scattering. We also show how rotational diffusion tensor restraints can be used for docking complexes using the dimeric HIV-1 protease and the EIN-HPr complexes as examples. In the former case, the rotational diffusion tensor restraints are sufficient in their own right to determine the position of one subunit relative to another. In the latter case, rotational diffusion tensor restraints complemented by highly ambiguous distance restraints derived from chemical shift perturbation mapping and a hydrophobic contact potential are sufficient to correctly dock EIN to HPr. In each case, the cluster containing the lowest-energy structure corresponds to the correct solution. C1 [Suh, Jeong-Yong; Grishaev, Alexander; Clore, G.

GlnBP consists of two globular domains connected by a hinge. Using the ligand-free ("open") conformation as a starting point, conjoined rigid-body/torsion-angle simulated annealing calculations were performed using backbone (1)H(N)-PREs as a major source of distance information. Paramagnetic probe flexibility was accounted for via a multiple-conformer representation. A conventional approach where the entire PRE data set is enforced at once during simulated annealing yielded poor results due to inappropriate conformational sampling of the probe. On the other hand, significant improvements in coordinate accuracy were obtained by estimating the probe sampling space prior to structure calculation. Such sampling is achieved by refining the ensemble of probe conformers with intradomain PRIES only, keeping the protein backbone fixed in the open form. Subsequently, while constraining the probe to the previously found conformations, the domains are allowed to move relative to each other under the influence of the non-intradomain PREs, giving the hinge region torsional degrees of freedom. Thus, by partitioning the protocol into "probe sampling" and "backbone sampling" stages, structures significantly closer to the X-ray structure of ligand-bound GlnBP were obtained.

TI Underlying Causes of the Black-White Racial Disparity in Breast Cancer Mortality: A Population-Based Analysis SO JOURNAL OF THE NATIONAL CANCER INSTITUTE LA English DT Article ID UNITED-STATES; SURVIVAL; TRENDS; WOMEN; DIAGNOSIS; OBESITY; RATES; RACE; AGE AB In the United States, a black-to-white disparity in age-standardized breast cancer mortality rates emerged in the 1980s and has widened since then. To further explore this racial disparity, black-to-white rate ratios (RRs(BW)) for mortality, incidence, hazard of breast cancer death, and incidence-based mortality (IBM) were investigated using data from the National Cancer Institute's Surveillance, Epidemiology, and End Results program on 244 786 women who were diagnosed with breast cancer from January 1990 through December 2003 and followed through December 2004. A counterfactual approach was used to examine the expected IBM RRs(BW), assuming equal distributions for estrogen receptor (ER) expression, and/or equal hazard rates of breast cancer death, among black and white women. From 1990 through 2004, mortality RR(BW) was greater than 1.0 and widened over time (age-standardized breast cancer mortality rates fell from 36 to 29 per 100 000 for blacks and from 30 to 22 per 100 000 for whites). In contrast, incidence RR(BW) was generally less than 1.0. Absolute hazard rates of breast cancer death declined substantially for ER-positive tumors and modestly for ER-negative tumors but were persistently higher for blacks than whites. Equalizing the distributions of ER expression in blacks and whites decreased the IBM RR(BW) slightly. Interestingly, the black-to-white disparity in IBM RR(BW) was essentially eliminated when hazard rates of breast cancer death were matched within each ER category. The black-to-white disparity in age-standardized breast cancer mortality was largely driven by the higher hazard rates of breast cancer death among black women, diagnosed with the disease, irrespective of ER expression, and especially in the first few years following diagnosis. Greater emphasis should be placed on identifying the etiology of these excess hazards and developing therapeutic strategies to address them.

TI Dietary Fatty Acids and Pancreatic Cancer in the NIH-AARP Diet and Health Study SO JOURNAL OF THE NATIONAL CANCER INSTITUTE LA English DT Article ID FOOD FREQUENCY QUESTIONNAIRES; RETIRED-PERSONS DIET; NATIONAL-INSTITUTES; NUTRITIONAL FACTORS; INSULIN-RESISTANCE; MEASUREMENT ERROR; BREAST-CANCER; AMERICAN-ASSOCIATION; CONFIDENCE-INTERVALS; PROSTATE-CANCER AB Previous research relating dietary fat, a modifiable risk factor, to pancreatic cancer has been inconclusive. We prospectively analyzed the association between intakes of fat, fat subtypes, and fat food sources and exocrine pancreatic cancer in the National Institutes of Health-AARP Diet and Health Study, a US cohort of 308 736 men and 216 737 women who completed a 124-item food frequency questionnaire in 1995-1996. Hazard ratios (HRs) and 95% confidence intervals (CIs) were calculated using Cox proportional hazards regression models, with adjustment for energy intake, smoking history, body mass index, and diabetes. Statistical tests were two-sided. Over an average follow-up of 6.3 years, 865 men and 472 women were diagnosed with exocrine pancreatic cancer (45.0 and 34.5 cases per 100 000 person-years, respectively). After multivariable adjustment and combination of data for men and women, pancreatic cancer risk was directly related to the intakes of total fat (highest vs lowest quintile, 46.8 vs 33.2 cases per 100 000 person-years, HR = 1.23, 95% CI = 1.03 to 1.46; P(trend) = .03), saturated fat (51.5 vs 33.1 cases per 100 000 person-years, HR = 1.36, 95% CI = 1.14 to 1.62; P(trend) < .001), and monounsaturated fat (46.2 vs 32.9 cases per 100 000 person-years, HR = 1.22, 95% CI = 1.02 to 1.46; P(trend) = .05) but not polyunsaturated fat. The associations were strongest for saturated fat from animal food sources (52.0 vs 32.2 cases per 100 000 person-years, HR = 1.43, 95% CI = 1.20 to 1.70; P(trend) < .001); specifically, intakes from red meat and dairy products were both statistically significantly associated with increased pancreatic cancer risk (HR = 1.27 and 1.19, respectively). In this large prospective cohort with a wide range of intakes, dietary fat of animal origin was associated with increased pancreatic cancer risk. C1 [Thiebaut, Anne C.

CA kConFab Investigators AOCS Grp Breast Canc Assoc Consortium TI Risk of Estrogen Receptor-Positive and -Negative Breast Cancer and Single-Nucleotide Polymorphism 2q35-rs13387042 SO JOURNAL OF THE NATIONAL CANCER INSTITUTE LA English DT Article ID GENOME-WIDE ASSOCIATION; CONFER SUSCEPTIBILITY; COMMON VARIANTS AB A recent genome-wide association study identified single-nucleotide polymorphism (SNP) 2q35-rs13387042 as a marker of susceptibility to estrogen receptor (ER)-positive breast cancer. We attempted to confirm this association using the Breast Cancer Association Consortium. 2q35-rs13387042 SNP was genotyped for 31 510 women with invasive breast cancer, 1101 women with ductal carcinoma in situ, and 35 969 female control subjects from 25 studies. Odds ratios (ORs) were estimated by logistic regression, adjusted for study. Heterogeneity in odds ratios by each of age, ethnicity, and study was assessed by fitting interaction terms. Heterogeneity by each of invasiveness, family history, bilaterality, and hormone receptor status was assessed by subclassifying case patients and applying polytomous logistic regression. All statistical tests were two-sided. We found strong evidence of association between rs13387042 and breast cancer in white women of European origin (per-allele OR = 1.12, 95% confidence interval [CI] = 1.09 to 1.15; P(trend) = 1.0 x 10(-19)). The odds ratio was lower than that previously reported (P = .02) and did not vary by age or ethnicity (all P >= .2). However, it was higher when the analysis was restricted to case patients who were selected for a strong family history (P = .02). An association was observed for both ER-positive (OR = 1.14, 95% CI = 1.10 to 1.17; P = 10(-15)) and ER-negative disease (OR = 1.10, 95% CI = 1.04 to 1.15; P = .0003) and both progesterone receptor (PR)-positive (OR = 1.15, 95% CI = 1.11 to 1.19; P = 5 x 10(-14)) and PR-negative disease (OR = 1.10, 95% CI = 1.06 to 1.15; P = .00002). The rs13387042 is associated with both ER-positive and ER-negative breast cancer in European women. C1 [Benitez, Javier] Spanish Natl Canc Res Ctr CNIO, Human Genet Grp, Madrid 29029, Spain.

Visualizing NLs of patients with MS using magnetic resonance imaging (MRI) poses several significant challenges. We optimized the inversion time (TI) of T(1)-based magnetization-prepared rapid acquisition gradient-echo (MPRAGE) images by suppressing the signal of the lesions and enhancing their appearance as hypo intensities, on the basis of the derived quantitative T(1) measurements. The latter were achieved by the means of 2D inversion recovery fast spin echo (IR-FSE), repeated using different inversion times (TI). Comparisons of detection of NLs by MPRAGE and dual echo T(2) weighted (T(2)W) and proton density (PD) W. Four coronal brain slices from a deceased MS patient and two coronal brain slices from two formerly healthy donors were imaged using a 3 Tesla magnet (3 T) equipped with a multi-channel coil. Based upon the averaged T1 values computed from the MS specimen as well as visual inspection, an optimal TI of 380 ms was selected for the MPRAGE image. No NLs were seen in the specimens of the two healthy donors. Of the 40 total NLs observed, 8 (20%) were visible in all three sequences employed. Three (7.5%) NLs were visible only in the PDW image and 5 (12.5%) were seen only in the T(2)W image. Four NLs (10%) had clearly unique conspicuity in the MPRAGE image. Of those, 3 were retrospectively scored in the PDW image (1 NL) or in the T2W image (2 NLs). We conclude that for the detection of MS-related NLs, high-resolution T(1)-based MPRAGE and T(2)-W images offer complementary information and the combination of the two image sequences is crucial for increasing the sensitivity of detecting MS-induced NLs.

TI Variation in Antagonism of the Interferon Response to Rotavirus NSP1 Results in Differential Infectivity in Mouse Embryonic Fibroblasts SO JOURNAL OF VIROLOGY LA English DT Article ID REGULATORY FACTOR-3; I INTERFERON; CHILDREN; MICE; DEGRADATION; DIARRHEA; ALPHA; CELLS; TRANSACTIVATION; ACTIVATION AB Rotavirus NSP1 has been shown to function as an E3 ubiquitin ligase that mediates proteasome-dependent degradation of interferon (IFN) regulatory factors (IRF), including IRF3, -5, and -7, and suppresses the cellular type I IFN response. However, the effect of rotavirus NSP1 on viral replication is not well defined. Prior studies used genetic analysis of selected reassortants to link NSP1 with host range restriction in the mouse, suggesting that homologous and heterologous rotaviruses might use their different abilities to antagonize the IFN response as the basis of their host tropisms. Using a mouse embryonic fibroblast (MEF) model, we demonstrate that heterologous bovine (UK and NCDV) and porcine (OSU) rotaviruses fail to effectively degrade cellular IRF3, resulting in IRF3 activation and beta IFN (IFN-beta) secretion. As a consequence of this failure, replication of these viruses is severely restricted in IFN-competent wild-type, but not in IFN-deficient (IFN-alpha/beta/gamma receptor- or STAT1-deficient) MEFs. On the other hand, homologous murine rotaviruses (ETD or EHP) or the heterologous simian rotavirus (rhesus rotavirus [RRV]) efficiently degrade cellular IRF3, diminish IRF3 activation and IFN-beta secretion and are not replication restricted in wild-type MEFs. Genetic reassortant analysis between UK and RRV maps the distinctive phenotypes of IFN antagonism and growth restriction in wild-type MEFs to NSP1. Therefore, there is a direct relationship between the replication efficiencies of different rotavirus strains in MEFs and strain-related variations in NSP1-mediated antagonism of the type I IFN response.

TI Initiation of Antiretroviral Therapy 48 Hours after Infection with Simian Immunodeficiency Virus Potently Suppresses Acute-Phase Viremia and Blocks the Massive Loss of Memory CD4(+) T Cells but Fails To Prevent Disease SO JOURNAL OF VIROLOGY LA English DT Article ID HIGH-FREQUENCY; GASTROINTESTINAL-TRACT; RHESUS MACAQUES; MAMU-B-ASTERISK-08-POSITIVE MACAQUES; SIVMAC239 REPLICATION; HIV-1 INFECTION; SIV INFECTION; DEPLETION; MONKEYS; ESCAPE AB We investigated whether a 28-day course of potent antiretroviral therapy, initiated at a time point ( 48 h postinoculation) following simian immunodeficiency virus (SIV) inoculation when the acquisition of a viral infection was virtually assured, would sufficiently sensitize the immune system and result in controlled virus replication when treatment was stopped. The administration of tenofovir 48 h after SIV inoculation to six Mamu-A*01-negative rhesus macaques did, in fact, potently suppress virus replication in all of the treated rhesus macaques, but plasma viral RNA rapidly became detectable in all six animals following its cessation. Unexpectedly, the viral set points in the treated monkeys became established at two distinct levels. Three controller macaques had chronic phase virus loads in the range of 1 x 10(3) RNA copies/ml, whereas three noncontroller animals had set points of 2 x 10(5) to 8 x 10(5) RNA copies/ml. All of the noncontroller monkeys died with symptoms of immunodeficiency by week 60 postinfection, whereas two of the three controller animals were alive at week 80. Interestingly, the three controller macaques each carried major histocompatibility complex class I alleles that previously were reported to confer protection against SIV, and two of these animals generated cytotoxic T-lymphocyte escape viral variants during the course of their infections.

TI Delivery of Human Immunodeficiency Virus Vaccine Vectors to the Intestine Induces Enhanced Mucosal Cellular Immunity SO JOURNAL OF VIROLOGY LA English DT Article ID REPLICATION-DEFECTIVE ADENOVIRUS; CD8(+) T-CELLS; GASTROINTESTINAL-TRACT; ORAL IMMUNIZATION; RHESUS-MONKEYS; GENE DELIVERY; IN-VITRO; SIV INFECTION; EBOLA-VIRUS; MICE AB Effective vaccines for human immunodeficiency virus type 1 (HIV-1) will likely need to stimulate protective immunity in the intestinal mucosa, where HIV-1 infection causes severe CD4(+) T-cell depletion. While replication-competent recombinant adenovirus (rAd) vectors can stimulate adenovirus-specific mucosal immunity after replication, oral delivery of replication-defective rAd vectors encoding specific immunogens has proven challenging. In this study, we have systematically identified barriers to effective gut delivery of rAd vectors and identified sites and strategies to induce potent cellular and humoral immunity. Vector-mediated gene transfer by rAd5 was susceptible to low-pH buffer, gastric and pancreatic proteases, and extracellular mucins. Using ex vivo organ explants, we found that transduction with rAd5 was highest in the ileum and colon among all intestinal segments. Transgene expression was 100-fold higher after direct surgical introduction into the ileum than after oral gavage, with rAd5 showing greater potency than the rAd35 or the rAd41 vector. A single immunization of rAd5 encoding HIV-1 gp140B to the ileum stimulated potent CD8(+) T-cell responses in the intestinal and systemic compartments, and these responses were further enhanced by intramuscular rAd5 boosting. These studies suggest that induction of primary immune responses by rAd5 gut immunization and subsequent systemic boosting elicits potent antigen-specific gut mucosal responses.

In many cases, the numbers of mutants increased during successive passages, indicating strong selection pressure. This phenomenon provided an opportunity to investigate the formation of spontaneous mutations in vaccinia virus, which encodes its own cytoplasmic replication system, and a challenge to reduce the occurrence of mutations for vaccine production. Analysis of virus from individual plaques indicated that loss of expression was due to frameshift mutations, mostly by addition or deletion of a single nucleotide in runs of four to six Gs or Cs, and large deletions that included MVA DNA flanking the recombinant gene. Interruption of the runs of Gs and Cs by silent codon alterations and moving the recombinant gene to a site between essential, highly conserved MVA genes eliminated or reduced frameshifts and viable deletion mutants, respectively. The rapidity at which nonexpressing mutants accumulated depended on the individual env and gag-pol genes and their suppressive effects on virus replication. Both the extracellular and transmembrane domains contributed to the selection of nonexpressing Env mutants. Stability of an unstable Env was improved by swapping external or transmembrane domains with a more stable Env. Most dramatically, removal of the transmembrane and cytoplasmic domains stabilized even the most highly unstable Env. Understanding the causes of instability and taking preemptive actions will facilitate the development of rMVA and other poxviruses as human and veterinary recombinant vaccines.

Among the most promising filovirus vaccines under development is a system based on recombinant vesicular stomatitis virus (VSV) that expresses a single filovirus glycoprotein (GP) in place of the VSV glycoprotein (G). Here, we performed a proof-of-concept study in order to determine the potential of having one single-injection vaccine capable of protecting nonhuman primates against Sudan ebolavirus (SEBOV), Zaire ebolavirus (ZEBOV), Cote d'Ivoire ebolavirus (CIEBOV), and Marburgvirus (MARV). In this study, 11 cynomolgus monkeys were vaccinated with a blended vaccine consisting of equal parts of the vaccine vectors VSV Delta G/SEBOVGP, VSV Delta G/ZEBOVGP, and VSV Delta G/MARVGP. Four weeks later, three of these animals were challenged with MARV, three with CIEBOV, three with ZEBOV, and two with SEBOV. Three control animals were vaccinated with VSV vectors encoding a nonfilovirus GP and challenged with SEBOV, ZEBOV, and MARV, respectively, and five unvaccinated control animals were challenged with CIEBOV. Importantly, none of the macaques vaccinated with the blended vaccine succumbed to a filovirus challenge. As expected, an experimental control animal vaccinated with VSV Delta G/ZEBOVGP and challenged with SEBOV succumbed, as did the positive controls challenged with SEBOV, ZEBOV, and MARV, respectively. All five control animals challenged with CIEBOV became severely ill, and three of the animals succumbed on days 12, 12, and 14, respectively. The two animals that survived CIEBOV infection were protected from subsequent challenge with either SEBOV or ZEBOV, suggesting that immunity to CIEBOV may be protective against other species of Ebola virus. In conclusion, we developed an immunization scheme based on a single-injection vaccine that protects nonhuman primates against lethal challenge with representative strains of all human pathogenic filovirus species.

TI Murine Norovirus Infection Has No Significant Effect on Adaptive Immunity to Vaccinia Virus or Influenza A Virus SO JOURNAL OF VIROLOGY LA English DT Article ID MURINE-NOROVIRUS-1 INFECTION; RESPONSES; MICE; PROTEINS; ANTIBODY; DISEASE; CELLS; HELP AB Murine norovirus (MNV) is endemic in many research mouse colonies. Although MNV infections are typically asymptomatic in immunocompetent mice, the effects of MNV infection on subsequent experimental viral infections are poorly documented. Here, we infected C57BL/6 mice with MNV and then with either vaccinia virus or influenza A virus. MNV infection had no effect on CD8(+) T-cell or antibody responses to secondary viruses or to secondary virus-induced morbidity or mortality. While our findings suggest that MNV has little influence on host immunity in immunocompetent mice, we would urge caution regarding the potential effects of MNV on immune responses to viruses and other pathogens, which must be determined on a system-by-system basis.

Cyclic AMP acts as a chemoattractant and its production, secretion, and degradation are highly regulated. A key protein is the extracellular phosphodiesterase PdsA. In this study we examine the role and localization of PdsA during chemotaxis and streaming. We find that pdsA(-) cells respond chemotactically to a narrower range of chemoattractant concentrations compared with wild-type (WT) cells. Moreover, unlike WT cells, pdsA(-) cells do not form streams at low cell densities and form unusual thick and transient streams at high cell densities. We find that the intracellular pool of PdsA is localized to the endoplasmic reticulum, which may provide a compartment for storage and secretion of PdsA. Because we find that cAMP synthesis is normal in cells lacking PdsA, we conclude that signal degradation regulates the external cAMP gradient field generation and that the group migration behavior of these cells is compromised even though their signaling machinery is intact.

Relative risks (RRs) and 95% confidence intervals (CIs) of PD were estimated from a Cox proportional hazards model adjusting for potential confounders. Risk of PD was not significantly associated with any of the reproductive factors measured or exogenous estrogen use. Use of postmenopausal hormones, however, may modify the associations of smoking and caffeine intake with PD risk. The inverse relation between smoking and PD risk was attenuated among ever users of post-menopausal hormones (P for interaction = 0.05). Similar results were obtained for caffeine (P for interaction = 0.09). In exploratory analyses, women using progestin-only hormones were found to have an increased PD risk, but this result was based on a very small number of cases (n = 4). In this large longitudinal study, we found no evidence of a beneficial effect of exogenous or endogenous estrogens on risk of PD. The use of postmenopausal hormone use may interact with other risk factors, but findings are preliminary and need confirmation in other populations.

TI Opinions and Clinical Practices Related to Diagnosing and Managing Patients with Psychogenic Movement Disorders: An International Survey of Movement Disorder Society Members SO MOVEMENT DISORDERS LA English DT Article DE psychogenic movement disorders; medically unexplained symptoms; survey ID RANDOMIZED CONTROLLED-TRIAL; CONVERSION DISORDER; SYMPTOMS AB Five hundred and nineteen members of the Movement Disorder Society completed a 22-item questionnaire probing diagnostic and management issues in psychogenic movement disorders (PMD). When patients showed definite evidence of PMD with no other unexplained clinical features, approximately 20% said they informed patients of the diagnosis and requested no further neurological testing. The 51% who reported conducting standard neurological investigations to rule out organic causes before presenting the diagnosis to such patients had fewer years of fellowship training and fewer PMD patients seen per month. A non-PMD diagnosis was correlated with patients' normal social or personal functioning, little or no employment disruption, lack of non-physiologic findings, and lack of psychiatric history. Ongoing litigation was more predictive of the PMD diagnosis for US compared to non-US respondents. Two thirds of respondents, more commonly younger and academic clinician researchers, refer PMD patients to a psychiatrist or mental health specialist while also providing personal follow up. Physician reimbursement, insurability of PMD patients, and ongoing litigation interfered with managing PMD patients to a greater extent in the US compared to non-US countries. Acceptance of the diagnosis by the patient and identification and management of psychological stressors and concurrent psychiatric disorders were considered most important for predicting a favorable prognosis. These findings suggest that expert opinions and practices related to diagnosing and managing PMD patients differ among movement disorders neurologists. Some of the discrepancies may be accounted for by factors such as training, type of practice, volume of patients, and country of practice, but may also reflect absence of practice guidelines.

We investigated with functional magnetic resonance imaging (fMRI) during emotion processing changes in activity of the amygdala and of prefrontal cortex in patients with schizophrenia during 8 weeks of olanzapine treatment. Twelve previously drug-free/naive patients with schizophrenia were treated with olanzapine for 8 weeks and underwent two fMRI scans after 4 and 8 weeks of treatment during implicit and explicit emotional processing. Twelve healthy subjects were also scanned twice to control for potential repetition effects. Results showed a diagnosis by time interaction in left amygdala and a diagnosis by time by task interaction in right ventrolateral prefrontal cortex. In particular, activity in left amygdala was greater in patients than in controls at the first scan during both explicit and implicit processing. while it was lower in patients at the second relative to the first scan. Furthermore, during implicit processing, right ventrolateral prefrontal cortex activity was lower in patients than controls at the first scan, while it was greater in patients at the second relative to the first scan. These results suggest that longitudinal treatment with olanzapine may be associated with specific changes in activity of the amygdala and prefrontal cortex during emotional processing in schizophrenia.

Following a simple protein precipitation step, the supernatant was extracted on-line and directly injected into the system LC-ESI-MS. A relatively new type of monolithic column consisting of a silica rod with bimodal pore structure was used to achieve a retention time of 2.4 min with a very low backpressure at a flow rate of 1 ml/min. The assay was linear from 0.050 to 1.000 mu g/ml. The mean recovery was 91%. The mean inter-day and intra-day precisions were 1.85% and 2.83%, respectively. The combination of the automated solid phase extraction and the low retention time achieved with this columns increase the throughput and decrease the time of analysis of each sample. This technology is useful in order to improve the efficiency of the bioanalytical studies. Published by Elsevier B.V.

TI Analysis of USRDS: Incidence and Risk Factors for Pneumocystis jiroveci Pneumonia SO TRANSPLANTATION LA English DT Article DE PCP; USRDS; Transplant infection ID ORGAN-TRANSPLANT RECIPIENTS; CARINII-PNEUMONIA; RENAL-TRANSPLANTATION; INFECTION; IMMUNOSUPPRESSION; PREVENTION; SIROLIMUS AB Background. To investigate the effect of modern immunosuppression on the incidence, risk factors, morbidity, and mortality of Pneumocystis pneumonia (PCP) in recipients of kidney transplants. Methods. We conducted a retrospective cohort study of 32,757 Medicare primary transplant recipients in the United States Renal Data System from January 1, 2000 through July 31, 2004. PCP infection was defined by Medicare claims using International Classification of Disease, 9th Revision codes. The incidence of PCP infections, graft loss, and death were measured. Results. There were a total of 142 cases (cumulative incidence 0.4%) of PCP after kidney transplantation during the study period. By using multivariate analysis with Cox regression, expanded criteria donor, donation after cardiac death, and earlier year of transplant were associated with development of PCP disease. Induction immunosuppression and acute rejections were not associated with risk for PCP infections. However, based on adjusted hazard ratio (AHR), maintenance immunosuppression regimens containing the combination of tacrolimus and sirolimus (AHR 3.60, confidence interval [CI] 2.03-6.39), Neoral and mycophenolate mofetil (AHR 2.09, CI 1.31-3.31), and sirolimus and mycophenolate mofetil (AHR 2.77, Cl 1.40-5.47), were associated with development of PCP. As a time dependent variable, PCP was associated with an increased risk of both graft loss and death. Conclusion. PCP infections are rare in the modern era of prophylaxis; however, these infections are a serious risk factor for graft loss and patient death, in particular, in patients who are on sirolimus as part of the immunosuppressive regimen. The median time to development of PCP after transplant was 0.80 +/- 0.95 years, suggesting a longer period of PCP prophylaxis.

TI Isotropic periodic sum of electrostatic interactions for polar systems SO JOURNAL OF CHEMICAL PHYSICS LA English DT Article ID MOLECULAR-DYNAMICS SIMULATIONS; ARTIFICIAL PERIODICITY; DIELECTRIC-PROPERTIES; WATER; TRUNCATION; PROGRAM; FORCES; CHARMM AB Isotropic periodic sum (IPS) is a method to calculate long-range interactions based on homogeneity of simulation systems. Long-range interactions are represented by interactions with isotropic periodic images of a defined local region and can be reduced to short ranged IPS potentials. The original electrostatic three-dimensional (3D)-IPS potential was derived based on a nonpolar homogeneous approximation and its application is limited to nonpolar or weak polar systems. This work derived a polar electrostatic 3D-IPS potential based on polar interactions. For the convenience of application, polynomial functions with rationalized coefficients are proposed for electrostatic and Lennard-Jones 3D-IPS potentials. Model systems of various polarities and several commonly used solvent systems are simulated to evaluate the 3D-IPS potentials. It is demonstrated that for polar systems the polar electrostatic 3D-IPS potential has much improved accuracy as compared to the nonpolar 3D-IPS potential. For homogeneous systems, the polar electrostatic 3D-IPS potential with a local region radius or cutoff distance of as small as 10 angstrom can satisfactorily reproduce energetic, structural, and dynamic properties from the particle-meshed-Ewald method. For both homogeneous and heterogeneous systems, the 3D-IPS/discrete fast Fourier transform method using either the nonpolar or the polar electrostatic 3D-IPS potentials results in very similar simulation results.

TI Synergistic antitumor activity of oncolytic reovirus and chemotherapeutic agents in non-small cell lung cancer cells SO MOLECULAR CANCER LA English DT Article ID INDUCED APOPTOSIS; TUMOR-CELLS; MITOTIC CHECKPOINT; PANCREATIC-CANCER; INFECTION; THERAPY; PATHWAY; DEATH; GEMCITABINE; COMBINATION AB Background: Reovirus type 3 Dearing strain (ReoT3D) has an inherent propensity to preferentially infect and destroy cancer cells. The oncolytic activity of ReoT3D as a single agent has been demonstrated in vitro and in vivo against various cancers, including colon, pancreatic, ovarian and breast cancers. Its human safety and potential efficacy are currently being investigated in early clinical trials. In this study, we investigated the in vitro combination effects of ReoT3D and chemotherapeutic agents against human non-small cell lung cancer (NSCLC). Results: ReoT3D alone exerted significant cytolytic activity in 7 of 9 NSCLC cell lines examined, with the 50% effective dose, defined as the initial virus dose to achieve 50% cell killing after 48 hours of infection, ranging from 1.46 +/- 0.12 similar to 2.68 +/- 0.25 (mean +/- SD) log(10) pfu/cell. Chou-Talalay analysis of the combination of ReoT3D with cisplatin, gemcitabine, or vinblastine demonstrated strong synergistic effects on cell killing, but only in cell lines that were sensitive to these compounds. In contrast, the combination of ReoT3D and paclitaxel was invariably synergistic in all cell lines tested, regardless of their levels of sensitivity to either agent. Treatment of NSCLC cell lines with the ReoT3D-paclitaxel combination resulted in increased poly (ADP-ribose) polymerase cleavage and caspase activity compared to single therapy, indicating enhanced apoptosis induction in dually treated NSCLC cells. NSCLC cells treated with the ReoT3D-paclitaxel combination showed increased proportions of mitotic and apoptotic cells, and a more pronounced level of caspase-3 activation was demonstrated in mitotically arrested cells. Conclusion: These data suggest that the oncolytic activity of ReoT3D can be potentiated by taxanes and other chemotherapeutic agents, and that the ReoT3D-taxane combination most effectively achieves synergy through accelerated apoptosis triggered by prolonged mitotic arrest.

TI Practice Parameter update: Management issues for women with epilepsy-Focus on pregnancy (an evidence-based review): Teratogenesis and perinatal outcomes Report of the Quality Standards Subcommittee and Therapeutics and Technology Assessment Subcommittee of the American Academy of Neurology and American Epilepsy Society SO NEUROLOGY LA English DT Review ID ANTIEPILEPTIC DRUGS; IN-UTERO; MATERNAL EPILEPSY; CONGENITAL-MALFORMATIONS; PSYCHOMOTOR DEVELOPMENT; ANTICONVULSANT DRUGS; PRENATAL EXPOSURE; CHILDREN; INTELLIGENCE; VALPROATE AB Objective: To reassess the evidence for management issues related to the care of women with epilepsy (WWE) during pregnancy. Methods: Systematic review of relevant articles published between January 1985 and June 2007. Results: It is highly probable that intrauterine first-trimester valproate (VPA) exposure has higher risk of major congenital malformations (MCMs) compared to carbamazepine and possible compared to phenytoin or lamotrigine. Compared to untreated WWE, it is probable that VPA as part of polytherapy and possible that VPA as monotherapy contribute to the development of MCMs. It is probable that antiepileptic drug (AED) polytherapy as compared to monotherapy regimens contributes to the development of MCMs and to reduced cognitive outcomes. For monotherapy, intrauterine exposure to VPA probably reduces cognitive outcomes. Further, monotherapy exposure to phenytoin or phenobarbital possibly reduces cognitive outcomes. Neonates of WWE taking AEDs probably have an increased risk of being small for gestational age and possibly have an increased risk of a 1-minute Apgar score of <7. Recommendations: If possible, avoidance of valproate (VPA) and antiepileptic drug (AED) polytherapy during the first trimester of pregnancy should be considered to decrease the risk of major congenital malformations (Level B). If possible, avoidance of VPA and AED polytherapy throughout pregnancy should be considered to prevent reduced cognitive outcomes (Level B). If possible, avoidance of phenytoin and phenobarbital during pregnancy may be considered to prevent reduced cognitive outcomes (Level C). Pregnancy risk stratification should reflect that the offspring of women with epilepsy taking AEDs are probably at increased risk for being small for gestational age (Level B) and possibly at increased risk of 1-minute Apgar scores of <7 (Level C).

Cancer cell response to chemotherapeutic and radiation-induced DNA damage is mediated by multiple defense mechanisms including polo-like kinase 1 (Plk-1), protein kinase B (Akt-1), and/or p53 pathways leading to either apoptosis or cell cycle arrest. Subsequently, a subpopulation of arrested viable cancer cells may remain and recur despite aggressive and repetitive therapy. Here, we show that modulation (activation of Akt-1 and Plk-1 and repression of p53) of these pathways simultaneously results in paradoxical enhancement of the effectiveness of cytotoxic chemotherapy. We demonstrate that a small molecule inhibitor, LB-1.2, of protein phosphatase 2A (PP2A) activates Plk-1 and Akt-1 and decreases p53 abundance in tumor cells. Combined with temozolomide (TMZ; a DNA-methylating chemotherapeutic drug), LB-1.2 causes complete regression of glioblastoma multiforme (GBM) xenografts without recurrence in 50% of animals (up to 28 weeks) and complete inhibition of growth of neuroblastoma (NB) xenografts. Treatment with either drug alone results in only short-term inhibition/regression with all xenografts resuming rapid growth. Combined with another widely used anticancer drug, Doxorubicin (DOX, a DNA intercalating agent), LB-1.2 also causes marked GBM xenograft regression, whereas DOX alone only slows growth. Inhibition of PP2A by LB-1.2 blocks cell-cycle arrest and increases progression of cell cycle in the presence of TMZ or DOX. Pharmacologic inhibition of PP2A may be a general method for enhancing the effectiveness of cancer treatments that damage DNA or disrupt components of cell replication.

Recent work has demonstrated that human brain networks constructed from neuroimaging data have economical small-world properties that confer high efficiency of information processing at relatively low connection cost. However, it has been unclear how the architecture of complex brain networks functioning at different frequencies can be related to behavioral performance on cognitive tasks. Here, we show that impaired accuracy of working memory could be related to suboptimal cost efficiency of brain functional networks operating in the classical beta frequency band, 15-30 Hz. We analyzed brain functional networks derived from magnetoencephalography data recorded during working-memory task performance in 29 healthy volunteers and 28 people with schizophrenia. Networks functioning at higher frequencies had greater global cost efficiency than low-frequency networks in both groups. Superior task performance was positively correlated with global cost efficiency of the beta-band network and specifically with cost efficiency of nodes in left lateral parietal and frontal areas. These results are consistent with biophysical models highlighting the importance of beta-band oscillations for long-distance functional connections in brain networks and with pathophysiological models of schizophrenia as a dysconnection syndrome. More generally, they echo the saying that "less is more'': The information processing performance of a network can be enhanced by a sparse or low-cost configuration with disproportionately high efficiency.

As proposed, such screening could involve tens of millions of individuals, but detailed estimates of radiation doses and potential risk of radiation-induced cancer are not currently available. We estimated organ-specific radiation doses and associated cancer risks from coronary artery calcification screening with multidetector computed tomography according to patient age, frequency of screening, and scan protocol. Methods: Radiation doses delivered to adult patients were calculated from a range of available protocols using Monte Carlo radiation transport. Radiation risk models, derived using data from Japanese atomic bomb survivors and medically exposed cohorts, were used to estimate the excess lifetime risk of radiation-induced cancer. Results: The radiation dose from a single coronary artery calcification computed tomographic scan varied more than 10-fold (effective dose range, 0.8-10.5 mSv) depending on the protocol. In general, higher radiation doses were associated with higher x-ray tube current, higher tube potential, spiral scanning with low pitch, and retrospective gating. The wide dose variation also resulted in wide variation in estimated radiation-induced cancer risk. Assuming screening every 5 years from the age of 45 to 75 years for men and 55 to 75 years for women, the estimated excess lifetime cancer risk using the median dose of 2.3 mSv was 42 cases per 100 000 men (range, 14-200 cases) and 62 cases per 100 000 women (range, 21-300 cases). Conclusions: These radiation risk estimates can be compared with potential benefits from screening, when such estimates are available. Doses and therefore risks can be minimized by the use of optimized protocols. C1 [Kim, Kwang Pyo; de Gonzalez, Amy Berrington] NCI, Div Canc Epidemiol & Genet, NIH, Bethesda, MD 20892 USA.

However, in some cancer types MHC class I expression is associated with an unfavorable outcome. We explored the basis of MHC class I association with unfavorable prognostic marker expression in the case of medulloblastoma. Methods: We investigated expression of four essential components of MHC class I (heavy chain, beta 2m, TAPI and TAP2) in 10 medulloblastoma mRNA samples, a tissue microarray containing 139 medulloblastoma tissues and 3 medulloblastoma cell lines. Further, in medulloblastoma cell lines we evaluated the effects of HLA class I engagement on activation of ERK1/2 and migration in vitro. Results: The majority of specimens displayed undetectable or low levels of the heavy chains. Medulloblastomas expressing high levels of HLA class I displayed significantly higher levels of anaplasia and c-myc expression, markers of poor prognosis. Binding of beta 2m or a specific antibody to open forms of HLA class I promoted phosphorylation of ERK1/2 in medulloblastoma cell line with high levels, but not in the cell line with low levels of HLA heavy chain. This treatment also promoted ERK1/2 activation dependent migration of medulloblastoma cells. Conclusion: MHC class I expression in medulloblastoma is associated with anaplasia and c-myc expression, markers of poor prognosis. Peptide- and/or beta 2m-free forms of MHC class I may contribute to a more malignant phenotype of medulloblastoma by modulating activation of signaling molecules such as ERK1/2 that stimulates cell mobility.

We mapped an additional 40 consanguineous families segregating nonsyndromic hearing loss to the DFNB39 locus and refined the obligate interval to 1.2 Mb. The coding regions of all genes in this interval were sequenced, and no missense, nonsense, or frameshift mutations were found. We sequenced the noncoding sequences of genes, as well as noncoding genes, and found three mutations Clustered in intron 4 and exon 5 in the hepatocyte growth factor gene (HGF). Two intron 4 deletions occur in a highly conserved sequence that is part of the 3' Untranslated region of a previously undescribed short isoform of HGF The third mutation is a silent substitution, and we demonstrate that it affects splicing in vitro. HGF is involved in a wide variety of signaling pathways in many different tissues, yet these putative regulatory mutations cause a surprisingly specific phenotype, which is nonsydromic hearing loss. Two mouse models of Hgf dysregulation, one in which an Hgf transgene is ubiquitously overexpressed and the other a conditional knockout that deletes Hgf from a limited number of tissues, including the cochlea, result in deafness. Overexpression of HGF is associated with progressive degeneration of outer hair cells in the cochlea, whereas cochlear deletion of Hgf is associated with more general dysplasia.

Using primary neuronal culture and immortal cell line models, we show that expression of normal insulin or IGF-1 receptors confers cells with abilities to reduce exogenously applied A beta oligomers (also known as ADDLs) to monomers. In contrast, transfection of malfunctioning human insulin receptor mutants, identified originally from patient with insulin resistance syndrome, or inhibition of insulin and IGF-1 receptors via pharmacological reagents increases ADDL levels by exacerbating their aggregation. In healthy cells, activation of insulin and IGF-1 receptor reduces the extracellular ADDLs applied to cells via seemingly the insulin-degrading enzyme activity. Although insulin triggers ADDL internalization, IGF-1 appears to keep ADDLs on the cell surface. Nevertheless, both insulin and IGF-1 reduce ADDL binding, protect synapses from ADDL synaptotoxic effects, and prevent the ADDL-induced surface insulin receptor loss. Our results suggest that dysfunctions of brain insulin and IGF-1 receptors contribute to A beta aggregation and subsequent synaptic loss.

The effect of inhibiting these transporters on tissue exposure to imatinib remains unclear. Objective: To assess the role of these transporters on drug disposition, 50 mg/kg imatinib was administered to Balb/C mice, 30 minutes after receiving tariquidar (10 mg/kg), an inhibitor of both ABCB1 and ABCG2, or vehicle, via oral gavage. Methods: Quantitative determination of imatinib in mouse plasma, liver and brain was performed using a newly-developed and validated liquid-chromatography-mass spectrometric method. Results: Exposure to imatinib was 2.2-fold higher in plasma, liver and brain in mice that received tariquidar, as compared to those that received the vehicle (P = 0.001). The peak plasma concentration did not increase substantially, suggesting that tariquidar is affecting the distribution, metabolism and/or excretion of imatinib, rather than absorption. Though tariquidar increased the absolute exposure of imatinib, the brain-to-plasma ratio of imatinib was unaffected. Conclusion: This study suggests that intentional inhibition of ABCB1 and ABCG2 function at the blood-brain barrier is unlikely to significantly improve clinical outcome of imatinib with currently used dosing regimens.

Recently, the structures of the beta(1) and beta(2) adrenergic receptors and the adenosine A(2a) receptor were determined in the antagonist-bound state, a receptor conformation that is thought to be more stable than the agonist-bound state. In contrast to these receptors, the neurotensin (NT) receptor NTS1 is much less stable in detergent solution. We have therefore used a systematic mutational approach coupled with activity assays to identify receptor mutants suitable for crystallization, both alone and in complex with the peptide agonist NT. The best receptor mutant NTS1-7m contained four point mutations. It showed increased stability compared to the wild-type receptor, in the absence of ligand, after solubilization with a variety of detergents. In addition, NTS1-7m bound to NT was more stable than unliganded NTS1-7m. Of the four thermostabilizing mutations, only one residue (A86L) is predicted to be in the lipid environment. In contrast, 1260A appears to be buried within the transmembrane helix bundle, F342A may form a distant part of the putative ligand-binding site, whereas F358A is likely to be in a region that is important for receptor activation. NTS1-7m binds NT with a similar affinity for the wild-type receptor. However, agonist dissociation was slower, and NTS1-7m activated G-proteins poorly. The affinity of NTS1-7m for the antagonist SR48692 was also lower than that of the wildtype receptor. Thus, we have successfully stabilized NTS1 in an agonist-binding conformation that does not efficiently couple to G-proteins. (C) 2009 Elsevier Ltd. All rights reserved.

TI Dissociable Perceptual Effects of Visual Adaptation SO PLOS ONE LA English DT Article ID TILTED LINES; CORTEX; ORIENTATION; CONTRAST; CURVATURE; RESPONSES; DISCRIMINATION; REPRESENTATION; NORMALIZATION; MACAQUE AB Neurons in the visual cortex are responsive to the presentation of oriented and curved line segments, which are thought to act as primitives for the visual processing of shapes and objects. Prolonged adaptation to such stimuli gives rise to two related perceptual effects: a slow change in the appearance of the adapting stimulus (perceptual drift), and the distortion of subsequently presented test stimuli (adaptational aftereffects). Here we used a psychophysical nulling technique to dissociate and quantify these two classical observations in order to examine their underlying mechanisms and their relationship to one another. In agreement with previous work, we found that during adaptation horizontal and vertical straight lines serve as attractors for perceived orientation and curvature. However, the rate of perceptual drift for different stimuli was not predictive of the corresponding aftereffect magnitudes, indicating that the two perceptual effects are governed by distinct neural processes. Finally, the rate of perceptual drift for curved line segments did not depend on the spatial scale of the stimulus, suggesting that its mechanisms lie outside strictly retinotopic processing stages. These findings provide new evidence that the visual system relies on statistically salient intrinsic reference stimuli for the processing of visual patterns, and point to perceptual drift as an experimental window for studying the mechanisms of visual perception.

TI Antigenic and Genetic Characteristics of Swine-Origin 2009 A(H1N1) Influenza Viruses Circulating in Humans SO SCIENCE LA English DT Article ID A VIRUS; PHYLOGENETIC ANALYSIS; UNITED-STATES; NORTH-AMERICA; EVOLUTION; PIGS; PATHOGENICITY; TRANSMISSION; EMERGENCE; INFECTION AB Since its identification in April 2009, an A(H1N1) virus containing a unique combination of gene segments from both North American and Eurasian swine lineages has continued to circulate in humans. The lack of similarity between the 2009 A(H1N1) virus and its nearest relatives indicates that its gene segments have been circulating undetected for an extended period. Its low genetic diversity suggests that the introduction into humans was a single event or multiple events of similar viruses. Molecular markers predictive of adaptation to humans are not currently present in 2009 A(H1N1) viruses, suggesting that previously unrecognized molecular determinants could be responsible for the transmission among humans. Antigenically the viruses are homogeneous and similar to North American swine A(H1N1) viruses but distinct from seasonal human A(H1N1).

To study the impact of genetic variation in caspases on NHL risk, we analyzed tag single nucleotide polymorphisms (SNPs) in 12 caspase and related genes in 3 population-based case-control studies (1946 cases and 1808 controls). Gene-based analysis, adjusting for the number of tagSNPs genotyped in each gene, showed significant associations for CASP8, CASP9, and CASP1. SNP-based analysis showed that CASP8 rs6736233 (odds ratio (OR) (CG) = 1.21; OR (CC) = 2.13; P trend = .011); CASP9 rs4661636 (OR(CT) = 0.89; OR(TT) = 0.77; P trend = .011); and CASP1 rs1785882 (OR(AT) = 1.12; OR(AA) = 1.30; P trend = .0054) were significantly associated with NHL risk and consistent across studies. It is noteworthy that genetic variants in CASP8 were associated with risk of all major NHL subtypes. Our findings suggest that genetic variation in caspases may play an important role in lymphomagenesis.

It has also been generally accepted that approximately 2% of total body lymphocytes circulate in the blood. In the present study, we have used a nondepleting humanized anti-CD4 monoclonal antibody labeled with the gamma emitter indium-111 to visualize the CD4(+) T-cell pool in vivo in nonhuman primates with simian HIV infection. A strong correlation was noted between radiotracer uptake in spleen, tonsil, axillary lymph nodes, and peripheral blood CD4(+) T-cell counts (rho = 0.75, 0.93, and 0.85, respectively, P < .005). The relationship between radiotracer retention in lymphoid tissues and CD4(+) T-cell counts in the circulation was governed by an exponential law. These data provide an estimate for the total number of lymphocytes in the body as being between 1.9 and 2.9 x 10(12) and suggest that the partition between peripheral blood and lymphoid tissue is between 0.3% and 0.5%.

Bone marrow transplantation in OI children has produced a low engraftment rate, but surprisingly encouraging symptomatic improvements. In utero transplantation (IUT) may hold even more promise. However, systematic studies of both methods have so far been limited to a recessive mouse model. In this study, we evaluated intrauterine transplantation of adult bone marrow into heterozygous BrtlIV mice. Brtl is a knockin mouse with a classical glycine substitution in type I collagen [alpha 1(I)-Gly349Cys], dominant trait transmission, and a phenotype resembling moderately severe and lethal OI. Adult bone marrow donor cells from enhanced green fluorescent protein (eGFP) transgenic mice engrafted in hematopoietic and nonhematopoietic tissues differentiated to trabecular and cortical bone cells and synthesized up to 20% of all type I collagen in the host bone. The transplantation eliminated the perinatal lethality of heterozygous BrtlIV mice. At 2 months of age, femora of treated Brtl mice had significant improvement in geometric parameters (P<.05) versus untreated Brtl mice, and their mechanical properties attained wild-type values. Our results suggest that the engrafted cells form bone with higher efficiency than the endogenous cells, supporting IUT as a promising approach for the treatment of genetic bone diseases.

The accuracy improves when the structures are available, but current structure-based sequence alignment procedures still mis-align substantial numbers of residues. In order to correct such errors, we previously explored the possibility of replacing the residue-based dynamic programming algorithm in structure alignment procedures with the Seed Extension algorithm, which does not use a gap penalty. Here, we describe a new procedure called RSE (Refinement with Seed Extension) that iteratively refines a structure-based sequence alignment. Results: RSE uses SE (Seed Extension) in its core, which is an algorithm that we reported recently for obtaining a sequence alignment from two superimposed structures. The RSE procedure was evaluated by comparing the correctly aligned fractions of residues before and after the refinement of the structure-based sequence alignments produced by popular programs. CE, DaliLite, FAST, LOCK2, MATRAS, MATT, TM-align, SHEBA and VAST were included in this analysis and the NCBI's CDD root node set was used as the reference alignments. RSE improved the average accuracy of sequence alignments for all programs tested when no shift error was allowed. The amount of improvement varied depending on the program. The average improvements were small for DaliLite and MATRAS but about 5% for CE and VAST. More substantial improvements have been seen in many individual cases. The additional computation times required for the refinements were negligible compared to the times taken by the structure alignment programs. Conclusion: RSE is a computationally inexpensive way of improving the accuracy of a structure-based sequence alignment. It can be used as a standalone procedure following a regular structure-based sequence alignment or to replace the traditional iterative refinement procedures based on residue-level dynamic programming algorithm in many structure alignment programs.

In an effort to enhance interactions with protease backbone atoms, we have incorporated stereochemically defined methyl-2-pyrrolidonone and methyl oxazolidinone as the P1'-ligands. These ligands are designed to interact with Gly-27' carbonyl and Arg-8 side chain in the S1'-subsite of the HIV protease. We have investigated the potential of these ligands in combination with our previously developed bis-tetrahydrofuran (bis-THF) and cyclopentanyltetrahydrofuran (Cp-THF) as the P2-ligands. Inhibitor 19b with a (R)-aminomethyl-2-pyrrolidinone and a Cp-THF was shown to be the most potent compound. This inhibitor maintained near full potency against multi-PI-resistant clinical HIV-1 variants. A high resolution protein-ligand X-ray crystal structure of 19b-bound HIV-1 protease revealed that the P1'-pyrrolidinone heterocycle and the P2-Cp-ligand are involved in several critical interactions with the backbone atoms in the S1' and S2 subsites of HIV-1 protease.

Both processes use directed DNA double-strand breaks (DSBs) repaired by non-homologous end-joining (NHEJ). Errors in either V(D) J recombination or CSR can initiate chromosomal translocations, including oncogenic IgH locus (Igh) to c-myc (also known as Myc) translocations of peripheral B cell lymphomas. Collaboration between these processes has also been proposed to initiate translocations. However, the occurrence of V(D) J recombination in peripheral B cells is controversial. Here we show that activated NHEJ-deficient splenic B cells accumulate V(D) J-recombination-associated breaks at the lambda IgL locus (Igl), as well as CSR-associated Igh breaks, often in the same cell. Moreover, Igl and Igh breaks are frequently joined to form translocations, a phenomenon associated with specific Igh-Igl co-localization. Igh and c-myc also co-localize in these cells; correspondingly, the introduction of frequent c-myc DSBs robustly promotes Igh-c-myc translocations. Our studies show peripheral B cells that attempt secondary V(D) J recombination, and determine a role for mechanistic factors in promoting recurrent translocations in tumours.

SO NEW ENGLAND JOURNAL OF MEDICINE LA English DT Article ID DEFICIENCY SYNDROME; GENETIC RISK; AUTOIMMUNITY; PREGNANCY; CANCER; ALPHA; WOMEN AB Background: A previous report described the presence of autoantibodies against folate receptors in 75% of serum samples from women with a history of pregnancy complicated by a neural-tube defect, as compared with 10% of controls. We sought to confirm this finding in an Irish population, which traditionally has had a high prevalence of neural-tube defects. Methods: We performed two studies. Study 1 consisted of analysis of stored frozen blood samples collected from 1993 through 1994 from 103 mothers with a history of pregnancy complicated by a neural-tube defect (case mothers), 103 mothers with a history of pregnancy but no complication by a neural-tube defect (matched with regard to number of pregnancies and sampling dates), 58 women who had never been pregnant, and 36 men. Study 2, conducted to confirm that the storage of samples did not influence the folate-receptor autoantibodies, included fresh samples from 37 case mothers, 22 control mothers, 10 women who had never been pregnant, and 9 men. All samples were assayed for blocking and binding autoantibodies against folate receptors. Results: In Study 1, blocking autoantibodies were found in 17% of case mothers, as compared with 13% of control mothers (odds ratio, 1.54; 95% confidence interval [CI], 0.70 to 3.39), and binding autoantibodies in 29%, as compared with 32%, respectively (odds ratio, 0.82; 95% CI, 0.44 to 1.50). Study 2 showed similar results, indicating that sample degradation was unlikely. Conclusions: The presence and titer of maternal folate-receptor autoantibodies were not significantly associated with a neural-tube defect-affected pregnancy in this Irish population.

TI Molecular Dynamics Simulations of PIP2 and PIP3 in Lipid Bilayers: Determination of Ring Orientation, and the Effects of Surface Roughness on a Poisson-Boltzmann Description SO BIOPHYSICAL JOURNAL LA English DT Article ID ELECTROSTATIC SEQUESTRATION; LIQUID/LIQUID INTERFACES; NEUTRON-DIFFRACTION; COMPUTER-SIMULATION; INOSITOL LIPIDS; BASIC PEPTIDES; MEMBRANES; BINDING; MODEL; PROTEINS AB Molecular dynamics (MD) simulations of phosphatidylinositol (4,5)-bisphosphate (PIP2) and phosphatidylinositol (3,4,5) -trisphosphate (PIP3) in 1-palmitoyl 2-oleoyl phosphatidylcholine (POPC) bilayers indicate that the inositol rings are tilted similar to 40 degrees with respect to the bilayer surface, as compared with 17 degrees for the P-N vector of POPC. Multiple minima were obtained for the ring twist (analogous to roll for an airplane). The phosphates at position 1 of PIP2 and PIP3 are within an Angstrom of the plane formed by the phosphates of POPC; lipids in the surrounding shell are depressed by 0.5-0.8 angstrom, but otherwise the phosphoinositides do not substantially perturb the bilayer. Finite size artifacts for ion distributions are apparent for systems of similar to 26 waters/lipid, but, based on simulations with a fourfold increase of the aqueous phase, the phosphoinositide positions and orientations do not show significant size effects. Electrostatic potentials evaluated from Poisson-Boltzmann (PB) calculations show a strong dependence of potential height and ring orientation, with the maxima on the -25 mV surfaces (17.1 +/- 0.1 angstrom for PIP2 and 19.4 +/- 0.3 angstrom for PIP3) occurring near the most populated orientations from MD. These surfaces are well above the background height of 10 angstrom estimated for negatively charged cell membranes, as would be expected for lipids involved in cellular signaling. PB calculations on microscopically flat bilayers yield similar maxima as the MD-based (microscopically rough) systems, but show less fine structure and do not clearly indicate the most probable regions. Electrostatic free energies of interaction with pentalysine are also similar for the rough and flat systems. These results support the utility of a rigid/flat bilayer model for PB-based studies of PIP2 and PIP3 as long as the orientations are judiciously chosen.

Here, we develop, characterize, and apply a new procedure to extract information about binding to an immobile substrate from fluorescence correlation spectroscopy (FCS) autocorrelation data. We show that existing methods for analyzing such data by two-component diffusion fits can produce inaccurate estimates of diffusion constants and bound fractions, or even fail altogether to fit FCS binding data. By analyzing live-cell FCS measurements, we show that our new model can satisfactorily account for the binding interactions introduced by attaching a DNA binding domain to the dimerization domain derived from a site-specific transcription factor (the vitellogenin binding protein (VBP)). We find that our FCS estimates are quantitatively consistent with our fluorescence recovery after photobleaching (FRAP) measurements on the same VBP domains. However, due to the fast binding interactions introduced by the DNA binding domain, FCS generates independent estimates for the diffusion constant (6.7 +/- 2.4 mu m(2)/s) and the association (2 +/- 1.2 s(-1)) and dissociation (19 +/- 7 s(-1)) rates, whereas FRAP produces only a single, but a consistent, estimate, the effective-diffusion constant (4.4 +/- 1.4 mu m(2)/s), which depends on all three parameters. We apply this new FCS method to evaluate the efficacy of a potential anticancer drug that inhibits DNA binding of VBP in vitro and find that in vivo the drug inhibits DNA binding in only a subset of cells. In sum, we provide a straightforward approach to directly measure binding rates from FCS data.

TI Increased Mortality among Survivors of Myocardial Infarction with Kidney Dysfunction: the Contribution of Gaps in the use of Guideline-Based Therapies SO BMC CARDIOVASCULAR DISORDERS LA English DT Article ID ACUTE CORONARY SYNDROMES; STAGE RENAL-DISEASE; CARDIOVASCULAR-DISEASE; HEART-FAILURE; INSUFFICIENCY; OUTCOMES; ASSOCIATION; INHIBITORS; ASPIRIN; EVENTS AB Background: We assessed the degree to which differences in guideline-based medical therapy for acute myocardial infarction (AMI) contribute to the higher mortality associated with kidney disease. Methods: In the PREMIER registry, we evaluated patients from 19 US centers surviving AMI. Cox regression evaluated the association between estimated glomerular filtration rate (GFR) and time to death over two years, adjusting for demographic and clinical variables. The contribution of variation in guideline-based medical therapy to differences in mortality was then assessed by evaluating the incremental change in the hazard ratios after further adjustment for therapy. Results: Of 2426 patients, 26% had GFR >= 90, 44% had GFR = 60- < 90, 22% had GFR = 30- < 60, and 8% had GFR < 30 ml/min/1.73 m(2). Greater degrees of renal dysfunction were associated with greater 2-year mortality and lower rates of guideline-based therapy among eligible patients. For patients with severely decreased GFR, adjustment for differences in guideline-based therapy did not significantly attenuate the relationship with mortality (HR 3.82, 95% CI 2.39-6.11 partially adjusted; HR = 3.90, 95% CI 2.42-6.28 after adjustment for treatment differences). Conclusion: Higher mortality associated with reduced GFR after AMI is not accounted for by differences in treatment factors, underscoring the need for novel therapies specifically targeting the pathophysiological abnormalities associated with kidney dysfunction to improve survival.

Available treatments can induce objective tumor regression in a small percent of patients, but these responses are not always associated with improved long-term survival. The resistance of melanoma to therapy and its predestined recurrence are related to the genetic heterogeneity and genomic instability of the tumor. For many years these genetic alterations were thought to be linked to the accumulation of random mutations in functionally differentiated cells which transform them into malignant cells that have lost their ability to differentiate and have acquired drug resistance. In the last few years it has been largely demonstrated that melanoma as other solid tumors contains a subpopulation of cells (CSCs) considered the source of the primary tumor mass, of new tumor nodules and responsible for drug resistance and cancer recurrence. In this review, we provide an overview of findings and advances in CSCs research that are relevant to the initiation, natural history, and the response to treatment of malignant melanoma.

However, the factors that regulate PPAR gamma and C/EBP alpha expression during adipogenesis remain largely unclear. Here, we show PTIP, a protein that associates with histone H3K4 methyltransferases, regulates PPAR gamma and C/EBP alpha expression in mouse embryonic fibroblasts (MEFs) and during preadipocyte differentiation. PTIP deletion in MEFs leads to marked decreases of PPAR gamma expression and PPAR gamma-stimulated C/EBP alpha expression. Further, PTIP is essential for induction of PPAR gamma and C/EBP alpha expression during preadipocyte differentiation. Deletion of PTIP impairs the enrichment of H3K4 trimethylation and RNA polymerase II on PPAR gamma and C/EBP alpha promoters. Accordingly, PTIP(-/-) MEFs and preadipocytes all show striking defects in adipogenesis. Rescue of the adipogenesis defect in PTIP(-/-) MEFs requires coexpression of PPAR gamma and C/EBP alpha. Finally, deletion of PTIP in brown adipose tissue significantly reduces tissue weight. Thus, by regulating PPAR gamma and C/EBP alpha expression, PTIP plays a critical role in adipogenesis.

Objective To identify common genetic variants associated with cardiac structure and function by conducting a meta-analysis of genome-wide association data in 5 population-based cohort studies (stage 1) with replication (stage 2) in 2 other community-based samples. Design, Setting, and Participants Within each of 5 community-based cohorts comprising the EchoGen consortium (stage 1; n = 12 612 individuals of European ancestry; 55% women, aged 26-95 years; examinations between 1978-2008), we estimated the association between approximately 2.5 million single-nucleotide polymorphisms ( SNPs; imputed to the HapMap CEU panel) and echocardiographic traits. In stage 2, SNPs significantly associated with traits in stage 1 were tested for association in 2 other cohorts (n = 4094 people of European ancestry). Using a prespecified P value threshold of 5 x 10(-7) to indicate genome-wide significance, we performed an inverse variance-weighted fixed-effects meta-analysis of genome-wide association data from each cohort. Main Outcome Measures Echocardiographic traits: LV mass, internal dimensions, wall thickness, systolic dysfunction, aortic root, and left atrial size. Results In stage 1, 16 genetic loci were associated with 5 echocardiographic traits: 1 each with LV internal dimensions and systolic dysfunction, 3 each with LV mass and wall thickness, and 8 with aortic root size. In stage 2, 5 loci replicated (6q22 locus associated with LV diastolic dimensions, explaining < 1% of trait variance; 5q23, 12p12, 12q14, and 17p13 associated with aortic root size, explaining 1%-3% of trait variance). Conclusions We identified 5 genetic loci harboring common variants that were associated with variation in LV diastolic dimensions and aortic root size, but such findings explained a very small proportion of variance. Further studies are required to replicate these findings, identify the causal variants at or near these loci, characterize their functional significance, and determine whether they are related to overt cardiovascular disease.

TI VEGFR-1 Regulates Adult Olfactory Bulb Neurogenesis and Migration of Neural Progenitors in the Rostral Migratory Stream In Vivo SO JOURNAL OF NEUROSCIENCE LA English DT Article ID ENDOTHELIAL GROWTH-FACTOR; TYROSINE KINASE; STEM-CELLS; STIMULATES NEUROGENESIS; SUBVENTRICULAR ZONE; GENERATED NEURONS; VASCULAR NICHE; BLOOD-VESSELS; DENTATE GYRUS; BORN NEURONS AB The generation of new neurons in the olfactory bulb (OB) persists into adulthood and is a multistep process that includes proliferation, fate choice, migration, survival, and differentiation. Neural precursor cells destined to form olfactory interneurons arise in the subventricular zone (SVZ) and migrate along the rostral migratory stream (RMS) to the OB. Recently, some factors classically known from their effects on the vascular system have been found to influence different steps of adult neurogenesis. In the present study, we report a modulatory function for the vascular endothelial growth factor receptor-1 (VEGFR-1) in adult olfactory neurogenesis. We identified expression of VEGFR-1 in GFAP-positive cells within regions involved in neurogenesis of the adult mouse brain. To determine functions for VEGFR-1 in adult neurogenesis, we compared neural progenitor cell proliferation, migration, and differentiation from wild-type and VEGFR-1 signaling-deficient mice (Flt-1TK(-/-) mice). Our data show that VEGFR-1 signaling is involved in the regulation of proliferation of neuronal progenitor cells within the SVZ, migration along the RMS, and in neuronal differentiation and anatomical composition of interneuron subtypes within the OB. RMS migration in Flt-1TK(-/-) mice was altered mainly as a result of increased levels of its ligand VEGF-A, which results in an increased phosphorylation of VEGFR-2 in neuronal progenitor cells within the SVZ and the RMS. This study reveals that proper RMS migration is dependent on endogenous VEGF-A protein.

We examined the mutant peptide, D23N-A beta 40, by electron microscopy, X-ray diffraction, and solid-state NMR spectroscopy. D23N-A beta 40 forms Fibrils considerably faster than the wild-type peptide (k = 3.77 x 10(-3) min(-1) and 1.07 x 10(-4) min(-1) for D23N-A beta 40 and the wild-type peptide WT-A beta 40, respectively) and without a lag phase. Electron microscopy shows that D23N-A beta 40 forms fibrils with multiple morphologies. X-ray fiber diffraction shows a cross-beta pattern, with a sharp reflection at 4.7 angstrom and a broad reflection at 9.4 angstrom, which is notably smaller than the value for WT-A beta 40 fibrils (10.4 angstrom). Solid-state NMR measurements indicate molecular level polymorphism of the fibrils, with only a minority of D23N-A beta 40 fibrils containing the in-register, parallel P-sheet structure commonly found in WT-A beta 40 fibrils and most other amyloid fibrils. Antiparallel beta-sheet structures in the majority of fibrils are indicated by measurements of intermolecular distances through (13)C-(13)C and (15)N-(13)C dipole-dipole couplings. An intriguing possibility exists that there is a relationship between the aberrant structure of D23N-A beta 40 fibrils and the unusual vasculotropic clinical picture in these patients.

TI Systemic treatment of xenografts with vaccinia virus GLV-1h68 reveals the immunologic facet of oncolytic therapy SO BMC GENOMICS LA English DT Article ID MESSENGER-RNA AMPLIFICATION; GENE-EXPRESSION; IN-VIVO; THYMIDINE KINASE; BREAST-TUMORS; IMMUNE CELLS; CANCER; CARCINOMA; REJECTION; MELANOMA AB Background: GLV-1h68 is an attenuated recombinant vaccinia virus (VACV) that selectively colonizes established human xenografts inducing their complete regression. Results: Here, we explored xenograft/VACV/host interactions in vivo adopting organism-specific expression arrays and tumor cell/VACV in vitro comparing VACV replication patterns. There were no clear-cut differences in vitro among responding and non-responding tumors, however, tumor rejection was associated in vivo with activation of interferon-stimulated genes (ISGs) and innate immune host's effector functions (IEFs) correlating with VACV colonization of the xenografts. These signatures precisely reproduce those observed in humans during immune-mediated tissue-specific destruction (TSD) that causes tumor or allograft rejection, autoimmunity or clearance of pathogens. We recently defined these common pathways in the "immunologic constant of rejection" hypothesis (ICR). Conclusion: This study provides the first prospective validation of a universal mechanism associated with TSD. Thus, xenograft infection by oncolytic VACV, beyond offering a promising therapy of established cancers, may represent a reliable pre-clinical model to test therapeutic strategies aimed at modulating the central pathways leading to TSD; this information may lead to the identification of principles that could refine the treatment of cancer and chronic infection by immune stimulation or autoimmunity and allograft rejection through immune tolerance.

The nanomechanics of full length, native rabbit nebulin was investigated with an atomic force microscope by tethering, bracketing, and stretching full-length molecules via pairs of site-specific antibodies that were attached covalently, one to a protein resistant self-assembled monolayer of oligoethylene glycol and the other to the cantilever. Using this new nanomechanics platform that enables the identification of single molecule events via an unbiased analysis of detachment force and distance of all force curves, we showed that nebulin is elastic and extends to similar to 1 mu m by external force up to an antibody detachment force of similar to 300-400 pN. Upon stretching, nebulin unravels and yields force spectra with craggy mountain range profiles with variable numbers and heights of force peaks. The peak spacings, analyzed by the model-independent, empirical Hilbert-Huang transform method, displayed underlying periodicities at similar to 15 and similar to 22 nm that may result from the unfolding of one or more nebulin modules between force peaks. Nebulin may act as an elastic strain gauge that interacts optimally with actin only under appropriate strain and stress. This stretch to match protein ruler may also exert a compressive force that stabilizes thin filaments against stress during contraction. We propose that the elasticity of nebulin is integral and essential in the muscle sarcomere.

TI PERMEABILITY OF THE BLOOD-BRAIN BARRIER DEPENDS ON BRAIN TEMPERATURE SO NEUROSCIENCE LA English DT Article DE brain hyperthermia; blood-brain barrier; acute astrocytic activation; edema ID NORMOTENSIVE YOUNG-RATS; CENTRAL-NERVOUS-SYSTEM; GLIAL-CELLS; METHAMPHETAMINE INTOXICATION; HEAT-STRESS; IN-VITRO; HYPERTHERMIA; EDEMA; INJURY; HYPOTHERMIA AB Increased permeability of the blood-brain barrier (BBB) has been reported in different conditions accompanied by hyperthermia, but the role of brain temperature per se in modulating brain barrier functions has not been directly examined. To delineate the contribution of this factor, we examined albumin immunoreactivity in several brain structures (cortex, hippocampus, thalamus and hypothalamus) of pentobarbital-anesthetized rats (50 mg/kg i.p.), which were passively warmed to different levels of brain temperature (32-42 degrees C). Similar brain structures were also examined for the expression of glial fibrillary acidic protein (GFAP), an index of astrocytic activation, water and ion content, and morphological cell abnormalities. Data were compared with those obtained from drug-free awake rats with normal brain temperatures (36-37 degrees C). The numbers of albumin- and GFAP-positive cells strongly correlate with brain temperature, gradually increasing from similar to 38.5 degrees C and plateauing at 41-42 degrees C. Brains maintained at hyperthermia also showed larger content of brain water and Na(+), K(+) and Cl(-) as well as structural abnormalities of brain cells, all suggesting acute brain edema. The latter alterations were seen at similar to 39 degrees C, gradually progressed with temperature increase, and peaked at maximum hyperthermia. Temperature-dependent changes in albumin immunoreactivity tightly correlated with GFAP immunoreactivity, brain water, and numbers of abnormal cells; they were found in each tested area, but showed some structural specificity. Notably, a mild BBB leakage, selective glial activation, and specific cellular abnormalities were also found in the hypothalamus and piriform cortex during extreme hypothermia (32-33 degrees C); in contrast to hyperthermia these changes were associated with decreased levels of brain water, Na(+) and K(+), suggesting acute brain dehydration. Therefore, brain temperature per se is an important factor in regulating BBB permeability, alterations in brain water homeostasis, and subsequent structural abnormalities of brain cells.

TI A novel analytical approach to the prediction of respiratory diaphragm motion based on external torso volume change SO PHYSICS IN MEDICINE AND BIOLOGY LA English DT Article ID 4-DIMENSIONAL COMPUTED-TOMOGRAPHY; RADIATION-THERAPY; TUMOR MOTION; ORGAN MOTION; RADIOTHERAPY; TRACKING; LUNG; CT; SURFACE; MARKERS AB An analytical approach to predict respiratory diaphragm motion should have advantages over a correlation-based method, which cannot adapt to breathing pattern changes without re-calibration for a changing correlation and/or linear coefficient. To quantitatively calculate the diaphragm motion, a new expandable 'piston' respiratory (EPR) model was proposed and tested using 4DCT torso images of 14 patients. The EPR model allows two orthogonal lung motions (with a few volumetric constraints): (1) the lungs expand (Delta V(EXP)) with the same anterior height variation as the thoracic surface, and (2) the lungs extend (Delta V(EXT)) with the same inferior distance as the volumetrically equivalent 'piston' diaphragm. A volume conservation rule (VCR) established previously (Li et al 2009 Phys. Med. Biol. 54 1963-78) was applied to link the external torso volume change (TVC) to internal lung volume change (LVC) via lung air volume change (AVC). As the diaphragm moves inferiorly, the vacant space above the diaphragm inside the rib cage should be filled by lung tissue with a volume equal to Delta V(EXT) (=LVC - Delta V(EXP)), while the volume of non-lung tissues in the thoracic cavity should conserve. It was found that Delta V(EXP) accounted for 3-24% of the LVC in these patients. The volumetric shape of the rib cage, characterized by the variation of cavity volume per slice over the piston motion range, deviated from a hollow cylinder by -1.1% to 6.0%, and correction was made iteratively if the variation is > 3%. The predictions based on the LVC and TVC (with a conversion factor) were compared with measured diaphragm displacements (averaged from six pivot points), showing excellent agreements (0.2 +/- 0.7 mm and 0.2 +/- 1.2 mm, respectively), which are within clinically acceptable tolerance. Assuming motion synchronization between the piston and points of interest along the diaphragm, point motion was estimated but at higher uncertainty (similar to 10% +/- 4%). This analytical approach provides a patient-independent technique to calculate the patient-specific diaphragm motion, using the anatomical and respiratory volumetric constraints.

Such models cannot handle motions (such as between "closed" and "open" states of an enzyme, or between conformers of a partially disordered system) where the shape of the molecule (and hence its rotational diffusion behavior) fluctuates. We provide here a formalism for dealing with such problems. The model involves jumps between discrete conformers with different overall diffusion tensors, and a master (rate) equation to describe the transitions between these conformers. Numerical examples are given for a two-site jump model where global and local motions are concerted, showing how the rate of conformational transitions (relative to the rate of rotational diffusion) affects the observed relaxation parameters.

To better understand the molecular mechanisms of KSR1 function, we examined the interaction of KSR1 with each of the ERK cascade components, Raf, MEK, and ERK. Here, we identify a hydrophobic motif within the proline-rich sequence (PRS) of MEK1 and MEK2 that is required for constitutive binding to KSR1 and find that MEK binding and residues in the KSR1 CA1 region enable KSR1 to form a ternary complex with B-Raf and MEK following growth factor treatment that enhances MEK activation. We also find that docking of active ERK to the KSR1 scaffold allows ERK to phosphorylate KSR1 and B-Raf on feedback S/TP sites. Strikingly, feedback phosphorylation of KSR1 and B-Raf promote their dissociation and result in the release of KSR1 from the plasma membrane. Together, these findings provide unique insight into the signaling dynamics of the KSR1 scaffold and reveal that through regulated interactions with Raf and ERK, KSR1 acts to both potentiate and attenuate ERK cascade activation, thus regulating the intensity and duration of ERK cascade signaling emanating from the plasma membrane during growth factor signaling.

Here we provide evidence that the central ghrelin signaling system is required for alcohol reward. Central ghrelin administration (to brain ventricles or to tegmental areas involved in reward) increased alcohol intake in a 2-bottle (alcohol/water) free choice limited access paradigm in mice. By contrast, central or peripheral administration of ghrelin receptor (GHS-R1A) antagonists suppressed alcohol intake in this model. Alcohol-induced locomotor stimulation, accumbal dopamine release and conditioned place preference were abolished in models of suppressed central ghrelin signaling: GHS-R1A knockout mice and mice treated with 2 different GHS-R1A antagonists. Thus, central ghrelin signaling, via GHS-R1A, not only stimulates the reward system, but is also required for stimulation of that system by alcohol. Our data suggest that central ghrelin signaling constitutes a potential target for treatment of alcohol-related disorders.

A very recent study, finding similarities in awake humans and anesthetized primates, has suggested that DMN activity might not simply reflect ongoing conscious mentation but rather a more general form of network dynamics typical of complex systems. Here, by performing functional MRI in humans, it is shown that a natural, sleep-induced reduction of consciousness is reflected in altered correlation between DMN network components, most notably a reduced involvement of frontal cortex. This suggests that DMN may play an important role in the sustenance of conscious awareness.

However, depolarization-induced Ca2+ release and its functional importance as well as underlying signaling mechanisms in smooth muscle cells (SMCs) are largely unknown. Here we report that membrane depolarization can induce RyR-mediated local Ca2+ release, leading to a significant increase in the activity of Ca2+ sparks and contraction in airway SMCs. The increased Ca2+ sparks are independent of VDCCs and the associated extracellular Ca2+ influx. This format of local Ca2+ release results from a direct activation of G protein-coupled, M-3 muscarinic receptors in the absence of exogenous agonists, which causes activation of Gq proteins and phospholipase C, and generation of inositol 1,4,5-triphosphate (IP3), inducing initial Ca2+ release through IP3 receptors and then further Ca2+ release via RyR2 due to a local Ca2+-induced Ca2+ release process. These findings demonstrate an important mechanism for Ca2+ signaling and attendant physiological function in SMCs.

TI Profound CD4(+)/CCR5(+) T cell expansion is induced by CD8(+) lymphocyte depletion but does not account for accelerated SIV pathogenesis SO JOURNAL OF EXPERIMENTAL MEDICINE LA English DT Article ID SIMIAN-IMMUNODEFICIENCY-VIRUS; INFECTED RHESUS-MONKEYS; HIV-1 INFECTION; IN-VIVO; VIRAL REPLICATION; GASTROINTESTINAL-TRACT; IMMUNE-RESPONSES; IFN-GAMMA; CD4(+); MACAQUES AB Depletion of CD8(+) lymphocytes during acute simian immunodeficiency virus (SIV) infection of rhesus macaques (RMs) results in irreversible prolongation of peak-level viral replication and rapid disease progression, consistent with a major role for CD8(+) lymphocytes in determining postacute-phase viral replication set points. However, we report that CD8(+) lymphocyte depletion is also associated with a dramatic induction of proliferation among CD4(+) effector memory T (T-EM) cells and, to a lesser extent, transitional memory T (T-TrM) cells, raising the question of whether an increased availability of optimal (activated/proliferating), CD4(+)/CCR5(+) SIV "target" cells contributes to this accelerated pathogenesis. In keeping with this, depletion of CD8(+) lymphocytes in SIV. RMs led to a sustained increase in the number of potential CD4(+) SIV targets, whereas such depletion in acute SIV infection led to increased target cell consumption. However, we found that the excess CD4(+) T-EM cell proliferation of CD8(+) lymphocyte-depleted, acutely SIV-infected RMs was completely inhibited by interleukin (IL)-15 neutralization, and that this inhibition did not abrogate the rapidly progressive infection in these RMs. Moreover, although administration of IL-15 during acute infection induced robust CD4(+) T-EM and T-TrM cell proliferation, it did not recapitulate the viral dynamics of CD8(+) lymphocyte depletion. These data suggest that CD8(+) lymphocyte function has a larger impact on the outcome of acute SIV infection than the number and/or activation status of target cells available for infection and viral production.

We investigated these interactions in 4,334 children from a birth longitudinal cohort: the Avon Longitudinal Study of Parents and Children (ALSPAC). We measured emotional symptoms at 7 years with the Strengths and Difficulties Questionnaire. Mothers rated stressful life events between ages 5 and 7 years. Maternal depression was defined as a score >= 12 on the Edinburgh Postnatal Depression Scale at 2 or 8 months postnatally. Triallelic genoptyping of the 5-HTTLPR polymorphism was performed. We found strong associations between stressful life events (OR 1.19; 1.12-1.26; P < 0.01) and maternal postnatal depression (OR 1.91; 1.63-2.24; P < 0.01) with emotional symptoms in the children. There were no main 5-HTTLPR genotype effects or significant interactions between genotype and life events or maternal postnatal depression on emotional symptoms. There was marginal evidence (P = 0.08) for an interaction between stressful life events and genotype in boys only, with those in the low and high 5-HTTLPR expression groups showing stronger associations. In these 7-year-old children, we did not replicate previously reported G x E interactions between 5-HTTLPR and life events for emotional symptoms. Gene by environment interactions may be developmentally dependent and show variation depending on the type and levels of exposure and sex. Young cohorts are essential to improve our understanding of the impact of development on gene and environment interactions. (C) 2008 Wiley-Liss, Inc.

CA Bipolar Disorder Phenome Grp NIMH Genetics Initiative Bipolar TI Family-Based Association Study of Neuregulin 1 With Psychotic Bipolar Disorder SO AMERICAN JOURNAL OF MEDICAL GENETICS PART B-NEUROPSYCHIATRIC GENETICS LA English DT Article DE Neuregulin 1; bipolar disorder; psychosis; mood-incongruent psychosis; genetic association ID NO SIGNIFICANT ASSOCIATION; GENOME-WIDE ASSOCIATION; AT-RISK HAPLOTYPE; SUSCEPTIBILITY GENE; CANDIDATE GENES; SCHIZOAFFECTIVE DISORDER; DIAGNOSTIC INTERVIEW; SCOTTISH POPULATION; ROSCOMMON FAMILY; SCHIZOPHRENIA AB The Neuregulin 1 gene (NRG1) has been associated with schizophrenia, and, to a lesser extent, with bipolar disorder (BP). We investigated the association of NRG1 with BP in a large family sample, and then performed analyses according to the presence of psychotic features or mood-incongruent psychotic features. We genotyped 116 tagSNPs and four Icelandic "core" SNPs in 1,199 subjects from 314 nuclear families. Of 515 BP offspring, 341 had psychotic features, and 103 had mood-incongruent psychotic features. In single-marker and sliding window haplotype analyses using FBAT, there was little association using the standard BP or mood-incongruent psychotic BP phenotypes, but stronger signals were seen in the psychotic BP phenotype. The most significant associations with psychotic BP were in haplotypes within the 5' "core" region. The strongest global P-value was across three SNPs: NRG241930-NRG243177-rs7819063 (P = 0.0016), with an undertransmitted haplotype showing an individual P = 0.0007. The most significant individual haplotype was an undertransmitted two-allele subset of the above (NRG243177-rs7819063, P = 0.0004). Additional associations with psychotic BP were found across six SNPs in a 270 kb central region of the gene. The most 3' of these, rs7005606 (P = 0.0029), is located similar to 4 kb from the type I NRG1 isoform promoter. In sum, our study suggests that NRG1 may be specifically associated with the psychotic subset of BP; however, our results should be interpreted cautiously since they do not meet correction for multiple testing and await independent replication.

TI Sapap3 and Pathological Grooming in Humans: Results From the OCD Collaborative Genetics Study SO AMERICAN JOURNAL OF MEDICAL GENETICS PART B-NEUROPSYCHIATRIC GENETICS LA English DT Article DE genes; Dlgap3; obsessive-compulsive disorder; nail biting; trichotillomania ID OBSESSIVE-COMPULSIVE DISORDER; SPECTRUM DISORDERS; PEDIATRIC PROBANDS; ANXIETY DISORDERS; TRANSPORTER GENE; LINKAGE ANALYSIS; MESSENGER-RNA; TRICHOTILLOMANIA; FAMILY; ASSOCIATION AB SAP90/PSD95-associated protein (SAPAP) family proteins are post-synaptic density (PSD) components that interact with other proteins to form a key scaffolding complex at excitatory (glutamatergic) synapses. A recent study found that mice with a deletion of the Sapap3 gene groomed themselves excessively, exhibited increased anxiety-like behaviors, and had cortico-striatal synaptic defects, all of which were preventable with lentiviral-mediated expression of Sapap3 in the striatum; the behavioral abnormalities were also reversible with fluoxetine. In the current study, we sought to determine whether variation within the human Sapap3 gene was associated with grooming disorders (GDs: pathologic nail biting, pathologic skin picking, and/or trichotillomania) and/or obsessive-compulsive disorder (OCD) in 383 families thoroughly phenotyped for OCD genetic studies. We conducted family-based association analyses using the FBAT and GenAssoc statistical packages. Thirty-two percent of the 1,618 participants met criteria for a GD, and 65% met criteria for OCD. Four of six SNPs were nominally associated (P < 0.05) with at least one GD (genotypic relative risks: 1.6-3.3), and all three haplotypes were nominally associated with at least one GD (permuted P < 0.05). None of the SNPs or haplotypes were significantly associated with OCD itself. We conclude that Sapap3 is a promising functional candidate gene for human GDs, though further work is necessary to confirm this preliminary evidence of association. (C) 2008 Wiley-Liss, Inc.

In this protocol, phagemid DNA containing Uracil is used as a template to synthesize a complementary DNA strand using T7 DNA polymerase and an oligonucleotide primer including a site-specific DNA lesion. The ligated lesion-containing strand can be recovered after the phage-derived template DNA is degraded by treatment with E coli Uracil DNA glycosylase and Exonucleases I and III. The resulting product is a circular single-stranded DNA containing a defined DNA lesion suitable for in vitro translesion replication assays. Published by Elsevier B.V.

TI Overall and cancer related mortality among patients with ocular inflammation treated with immunosuppressive drugs: retrospective cohort study SO BRITISH MEDICAL JOURNAL LA English DT Article ID NATIONAL DEATH INDEX; RHEUMATOID-ARTHRITIS; FOLLOW-UP; RISK; MALIGNANCIES; CYCLOPHOSPHAMIDE; CYCLOSPORINE; ETANERCEPT; DISEASES; THERAPY AB Context Whether immunosuppressive treatment adversely affects survival is unclear. Objective To assess whether immunosuppressive drugs increase mortality. Design Retrospective cohort study evaluating overall and cancer mortality in relation to immunosuppressive drug exposure among patients with ocular inflammatory diseases. Demographic, clinical, and treatment data derived from medical records, and mortality results from United States National Death Index linkage. The cohort's mortality risk was compared with US vital statistics using standardised mortality ratios. Overall and cancer mortality in relation to use or non-use of immunosuppressive drugs within the cohort was studied with survival analysis. Setting Five tertiary ocular inflammation clinics. Patients 7957 US residents with non-infectious ocular inflammation, 2340 of whom received immunosuppressive drugs during follow up. Exposures Use of antimetabolites, T cell inhibitors, alkylating agents, and tumour necrosis factor inhibitors. Main outcome measures Overall mortality, cancer mortality. Results Over 66 802 person years (17 316 after exposure to immunosuppressive drugs), 936 patients died (1.4/100 person years), 230 (24.6%) from cancer. For patients unexposed to immunosuppressive treatment, risks of death overall (standardised mortality ratio 1.02, 95% confidence interval [CI] 0.94 to 1.11) and from cancer (1.10, 0.93 to 1.29) were similar to those of the US population. Patients who used azathioprine, methotrexate, mycophenolate mofetil, ciclosporin, systemic corticosteroids, or dapsone had overall and cancer mortality similar to that of patients who never took immunosuppressive drugs. In patients who used cyclophosphamide, overall mortality was not increased and cancer mortality was non-significantly increased. Tumour necrosis factor inhibitors were associated with increased overall (adjusted hazard ratio [HR] 1.99, 95% CI 1.00 to 3.98) and cancer mortality (adjusted HR 3.83, 1.13 to 13.01). Conclusions Most commonly used immunosuppressive drugs do not seem to increase overall or cancer mortality. Our results suggesting that tumour necrosis factor inhibitors might increase mortality are less robust than the other findings; additional evidence is needed.

Silencing of RRM1 and RRM2, which encode the large and small subunits of the human ribonucleotide reductase complex, respectively, markedly enhanced the cytotoxicity of the topoisomerase I inhibitor camptothecin (CPT). Silencing of RRM2 was also found to enhance DNA damage as measured by histone gamma-H2AX. Further studies showed that CPT up-regulates both RRM1 and RRM2 mRNA and protein levels and induces the nuclear translocation of RRM2. The checkpoint kinase 1 (Chk1) was up-regulated and activated in response to CPT, and CHEK1 down-regulation by siRNA and small molecule inhibitors of Chk1 blocked RRM2 induction by CPT. CHEK1 siRNA also suppressed E2F1 up-regulation by CPT, and silencing of E2F1 suppressed the up-regulation of RRM2. Silencing of ATR or ATM and inhibition of ATM activity by KU-55933 blocked Chk1 activation and RRM2 up-regulation. This study links the known components of CPT-induced DNA damage response with proteins required for the synthesis of dNTPs and DNA repair. Specifically, we propose that upon DNA damage, Chk1 activation, mediated by ATM and ATR, up-regulates RRM2 expression through the E2F1 transcription factor. Upregulation in RRM2 expression levels coupled with its nuclear recruitment suggests an active role for ribonucleotide reductase in the cellular response to CPT-mediated DNA damage that could potentially be exploited as a strategy for enhancing the efficacy of topoisomerase I inhibitors.

Here, we characterize PhLP-M1-G149, a G beta gamma-interacting construct derived from phosducin-like protein 1 (PhLP) as a differential inhibitor of G beta gamma, which, in endothelial cells, prevented sphingosine 1-phosphate- induced phosphorylation of AKT, glycogen synthase kinase 3 beta, cell migration, and tubulogenesis, while having no effect on ERK phosphorylation or hepatocyte growth factor-dependent responses. This construct attenuated the recruitment of phosphoinositide 3-kinase gamma (PI3K gamma) to the plasma membrane and the signaling to AKT in response to G beta gamma overexpression. In coimmunoprecipitation experiments, PhLP-M1-G149 interfered with the interaction between PI3K gamma and G beta gamma. Other PhLP- derived constructs interacted with G beta gamma but were not effective inhibitors of G beta gamma signaling to AKT or ERK. Our results indicate that PhLP-M1-G149 is a suitable tool to differentially modulate the G beta gamma-initiated pathway linking this heterodimer to AKT, endothelial cell migration, and in vitro angiogenesis. It can be also useful to further characterize the molecular determinants of the G beta gamma-PI3K gamma interaction.

Understanding the role of FANCJ in DNA metabolism and how FANCJ dysfunction leads to tumorigenesis requires mechanistic studies of FANCJ helicase and its protein partners. In this work, we have examined the ability of FANCJ to unwind DNA molecules with specific base damage that can be mutagenic or lethal. FANCJ was inhibited by a single thymine glycol, but not 8-oxoguanine, in either the translocating or nontranslocating strands of the helicase substrate. In contrast, the human RecQ helicases (BLM, RECQ1, and WRN) display strand-specific inhibition of unwinding by the thymine glycol damage, whereas other DNA helicases (DinG, DnaB, and UvrD) are not significantly inhibited by thymine glycol in either strand. In the presence of replication protein A (RPA), but not Escherichia coli single-stranded DNA-binding protein, FANCJ efficiently unwound the DNA substrate harboring the thymine glycol damage in the nontranslocating strand; however, inhibition of FANCJ helicase activity by the translocating strand thymine glycol was not relieved. Strand-specific stimulation of human RECQ1 helicase activity was also observed, and RPA bound with high affinity to single-stranded DNA containing a single thymine glycol. Based on the biochemical studies, we propose a model for the specific functional interaction between RPA and FANCJ on the thymine glycol substrates. These studies are relevant to the roles of RPA, FANCJ, and other DNA helicases in the metabolism of damaged DNA that can interfere with basic cellular processes of DNA metabolism.

However, relatively few in vivo functional studies have been reported on the roles of MMPs in postembryonic organ development. Amphibian metamorphosis is a unique model for studying MMP function during vertebrate development because of its dependence on thyroid hormone (T3) and the ability to easily manipulate this process with exogenous T3. The MMP stromelysin-3 (ST3) is induced by T3, and its expression correlates with cell death during metamorphosis. We have previously shown that ST3 is both necessary and sufficient for larval epithelial cell death in the remodeling intestine. To investigate the roles of ST3 in other organs and especially on different cell types, we have analyzed the effect of transgenic overexpression of ST3 in the tail of premetamorphic tadpoles. We report for the first time that ST3 expression, in the absence of T3, caused significant muscle cell death in the tail of premetamorphic transgenic tadpoles. On the other hand, only relatively low levels of epidermal cell death were induced by precocious ST3 expression in the tail, contrasting what takes place during natural and T3-induced metamorphosis when ST3 expression is high. This cell type-specific apoptotic response to ST3 in the tail suggests distinct mechanisms regulating cell death in different tissues. Furthermore, our analyses of laminin receptor, an in vivo substrate of ST3 in the intestine, suggest that laminin receptor cleavage may be an underlying mechanism for the cell type-specific effects of ST3.

This modification interrupts the laminar How of the mobile phase through the tube and continuously mixes the two phases through the column. The performance of this spiral tube assembly was tested by three types of two-phase solvent systems with different polarities each with a set of suitable test samples such as DNP-amino acids, dipeptides and proteins at the optimal elution modes. In general all these test samples yielded higher resolution with the lower mobile phase than the upper mobile phase. In the most hydrophobic two-phase solvent system composed of hexane-ethyl acetate-methanol-0.1 M hydrochloric acid (1:1:1:1, v/v/v/v), DNP-amino acids were separated with Rs-a (peak resolution based on the same Column capacity adjusted for comparison) at 4.40 and 73% of stationary phase retention at a flow rate of 0.5 ml/min with the lower mobile phase. In the polar solvent system composed of 1 butanol-acetic acid-water (4:1:5, v/v/v), dipeptide samples were resolved with Rs-a at 4.06, compared to 2.79 with the cross-pressed tube assembly at 45% stationary phase retention, each at a flow rate of 1 ml/min. Finally in the aqueous-aqueous polymer phase systems composed of polyethylene glycol 1000 - dibasic potassium phosphate each 12.5% (w/w) in water, protein samples were resolved with Rs-a at 2.53 compared to 1.10 with the cross-pressed tube assembly at 52% of stationary phase retention,each at a now rate of 1 ml/min. These results indicate that the present system substantially improves the partition efficiency with a satisfactory level of stationary phase retention by the lower mobile phase.

The stages of mammalian erythropoiesis include global gene inactivation, nuclear condensation, and enucleation to yield circulating erythrocytes, and some of the genes whose expression are altered by GATA-1 during this process are members of the p53 pathway. In this study, we demonstrate a specific in vitro interaction between the transactivation domain of p53 (p53TAD) and a segment of the GATA-1 DNA-binding domain that includes the carboxyl-terminal zinc-finger domain. We also show by immunoprecipitation that the native GATA-1 and p53 interact in erythroid cells and that activation of p53-responsive promoters in an erythroid cell line can be inhibited by the overexpression of GATA-1. Mutational analysis reveals that GATA-1 inhibition of p53 minimally requires the segment of the GATA-1 DNA-binding domain that interacts with p53TAD. This inhibition is reciprocal, as the activation of a GATA-1 responsive promoter can be inhibited by p53. Based on these findings, we conclude that inhibition of the p53 pathway by GATA-1 may be essential for erythroid cell development and survival.

TI Identification of TWSG1 as a second novel erythroid regulator of hepcidin expression in murine and human cells SO BLOOD LA English DT Article ID TWISTED-GASTRULATION; BETA-THALASSEMIA; IRON HOMEOSTASIS; BMP ANTAGONIST; COOLEY-ANEMIA; MOUSE MODEL; ERYTHROPOIESIS; HEMOJUVELIN; GENES; LIVER AB In thalassemia and other iron loading anemias, ineffective erythropoiesis and erythroid signaling molecules are thought to cause inappropriate suppression of a small peptide produced by hepatocytes named hepcidin. Previously, it was reported that the erythrokine GDF15 is expressed at very high levels in thalassemia and suppresses hepcidin expression. In this study, erythroblast expression of a second molecule named twisted gastrulation (TWSG1) was explored as a potential erythroid regulator of hepcidin. Transcriptome analyses suggest TWSG1 is produced during the earlier stages of erythropoiesis. Hepcidin suppression assays demonstrated inhibition by TWSG1 as measured by quantitative polymerase chain reaction (PCR) in dosed assays (1-1000 ng/mL TWSG1). In human cells, TWSG1 suppressed hepcidin indirectly by inhibiting the signaling effects and associated hepcidin up-regulation by bone morphogenic proteins 2 and 4 (BMP2/BMP4). In murine hepatocytes, hepcidin expression was inhibited by murine Twsg1 in the absence of additional BMP. In vivo studies of Twsg1 expression were performed in healthy and thalassemic mice. Twsg1 expression was significantly increased in the spleen, bone marrow, and liver of the thalassemic animals. These data demonstrate that twisted gastrulation protein interferes with BMP-mediated hepcidin expression and may act with GDF15 to dysregulate iron homeostasis in thalassemia syndromes.

TI SCF induces gamma-globin gene expression by regulating downstream transcription factor COUP-TFII SO BLOOD LA English DT Article ID STEM-CELL FACTOR; FACTOR NF-Y; FETAL-HEMOGLOBIN; PROTEIN PHOSPHATASE; EPSILON-GLOBIN; BINDING; ERYTHROPOIESIS; KIT; DIFFERENTIATION; ACTIVATION AB Increased fetal hemoglobin expression in adulthood is associated with acute stress erythropoiesis. However, the mechanisms underlying gamma-globin induction during the rapid expansion of adult erythroid progenitor cells have not been fully elucidated. Here, we examined COUP-TFII as a potential repressor of gamma-globin gene after stem cell factor (SCF) stimulation in cultured human adult erythroid progenitor cells. We found that COUP-TFII expression is suppressed by SCF through phosphorylation of serine/threonine phosphatase (PP2A) and correlated well with fetal hemoglobin induction. Furthermore, down-regulation of COUP-TFII expression with small interfering RNA (siRNA) significantly increases the gamma-globin expression during the erythroid maturation. Moreover, SCF-increased expression of NF-YA associated with redox regulator Ref-1 and cellular reducing condition enhances the effect of SCF on gamma-globin expression. Activation of Erk1/2 plays a critical role in SCF modulation of downstream transcriptional factor COUP-TFII, which is involved in the regulation of gamma-globin gene induction. Our data show that SCF stimulates Erk1/2 MAPK signaling pathway, which regulates the downstream repressor COUP-TFII by inhibiting serine/threonine phosphatase 2A activity, and that decreased COUP-TFII expression resulted in gamma-globin reactivation in adult erythropoiesis. These observations provide insight into the molecular pathways that regulate gamma-globin augmentation during stress erythropoiesis.

TI Ensemble approach to predict specificity determinants: benchmarking and validation SO BMC BIOINFORMATICS LA English DT Article ID FUNCTIONAL SPECIFICITY; DETERMINING RESIDUES; SEQUENCE ALIGNMENTS; PROTEIN FAMILIES; DIVERGENCE; SERVER; COMMON AB Background: It is extremely important and challenging to identify the sites that are responsible for functional specification or diversification in protein families. In this study, a rigorous comparative benchmarking protocol was employed to provide a reliable evaluation of methods which predict the specificity determining sites. Subsequently, three best performing methods were applied to identify new potential specificity determining sites through ensemble approach and common agreement of their prediction results. Results: It was shown that the analysis of structural characteristics of predicted specificity determining sites might provide the means to validate their prediction accuracy. For example, we found that for smaller distances it holds true that the more reliable the prediction method is, the closer predicted specificity determining sites are to each other and to the ligand. Conclusion: We observed certain similarities of structural features between predicted and actual subsites which might point to their functional relevance. We speculate that majority of the identified potential specificity determining sites might be indirectly involved in specific interactions and could be ideal target for mutagenesis experiments.

Given that current force fields differ significantly in their alpha-helical propensities, a correction to match experimental results would be highly desirable. We have determined simple backbone energy corrections for two force fields to reproduce the fraction of helix measured in short peptides at 300 K. As validation, we show that the optimized force fields produce results in excellent agreement with nuclear magnetic resonance experiments for folded proteins and short peptides not used in the optimization. However. despite the agreement at ambient conditions, the dependence of the helix content on temperature is too weak, a problem shared with other force fields. A fit of the Lifson-Roig helix-coil theory shows that both the enthalpy and entropy of helix formation are too small: the helix extension parameter w agrees well with experiment, but its entropic and enthalpic components are both only about half the respective experimental estimates. Our structural and thermodynamic analyses point toward the physical origins of these shortcomings in current force fields, and suggest ways to address them in future force-field development.

TI Telomerase modulates Wnt signalling by association with target gene chromatin SO NATURE LA English DT Article ID BETA-CATENIN; REVERSE-TRANSCRIPTASE; ANTEROPOSTERIOR AXIS; TRANSIENT ACTIVATION; CELL-PROLIFERATION; XENOPUS EMBRYOS; STEM-CELLS; IN-VIVO; MICE; MOUSE AB Stem cells are controlled, in part, by genetic pathways frequently dysregulated during human tumorigenesis. Either stimulation of Wnt/beta-catenin signalling or overexpression of telomerase is sufficient to activate quiescent epidermal stem cells in vivo, although the mechanisms by which telomerase exerts these effects are not understood. Here we show that telomerase directly modulates Wnt/beta-catenin signalling by serving as a cofactor in a beta-catenin transcriptional complex. The telomerase protein component TERT (telomerase reverse transcriptase) interacts with BRG1 (also called SMARCA4), a SWI/SNF-related chromatin remodelling protein, and activates Wnt-dependent reporters in cultured cells and in vivo. TERT serves an essential role in formation of the anterior-posterior axis in Xenopus laevis embryos, and this defect in Wnt signalling manifests as homeotic transformations in the vertebrae of Tert(-/-) mice. Chromatin immunoprecipitation of the endogenous TERT protein from mouse gastrointestinal tract shows that TERT physically occupies gene promoters of Wnt-dependent genes. These data reveal an unanticipated role for telomerase as a transcriptional modulator of the Wnt/beta-catenin signalling pathway.

Lusso, Paolo TI Evolution of SIV toward RANTES resistance in macaques rapidly progressing to AIDS upon coinfection with HHV-6A SO RETROVIROLOGY LA English DT Article ID HUMAN-IMMUNODEFICIENCY-VIRUS; HUMAN LYMPHOID-TISSUE; HUMAN-HERPESVIRUS 6; SMALL-MOLECULE; PRIMARY INFECTION; LYMPHOCYTES-T; HIV; TYPE-1; HUMAN-HERPESVIRUS-6; CELLS AB Background: Progression to AIDS is often associated with the evolution of HIV-1 toward increased virulence and/or pathogenicity. Evidence suggests that a virulence factor for HIV-1 is resistance to CCR5-binding chemokines, most notably RANTES, which are believed to play a role in HIV-1 control in vivo. HIV-1 can achieve RANTES resistance either by phenotypic switching from an exclusive CCR5 usage to an expanded coreceptor specificity, or by the acquisition of alternative modalities of CCR5 usage. An infectious agent that might promote the evolution of HIV-1 toward RANTES resistance is human herpesvirus 6A (HHV-6A), which is frequently reactivated in HIV-1-infected patients and is a potent RANTES inducer in lymphoid tissue. Results: SIV isolates obtained from pig-tailed macaques (M. nemestrina) after approximately one year of single infection with SIV(smE660) or dual infection with SIV(smE660) and HHV-6A(GS) were characterized for their growth capacity and sensitivity to HHV6A- and RANTES-mediated inhibition in human or macaque lymphoid tissues ex vivo. Four out of 4 HHV-6A-coinfected macaques, all of which progressed to full-blown AIDS within 2 years of infection, were found to harbor SIV variants with a reduced sensitivity to both HHV-6A and RANTES, despite maintaining an exclusive CCR5 coreceptor specificity; viruses derived from two of these animals replicated even more vigorously in the presence of exogenous HHV-6A or RANTES. The SIV variants that emerged in HHV-6A-coinfected macaques showed an overall reduced ex vivo replication capacity that was partially reversed upon addition of exogenous RANTES, associated with suppressed IL-2 and enhanced IFN-gamma production. In contrast, SIV isolates obtained from two singly-infected macaques, none of which progressed to AIDS, maintained HHV-6A/RANTES sensitivity, whereas the only AIDS progressor among singly-infected macaques developed an SIV variant with partial HHV-6A/RANTES resistance and increased replication capacity, associated with expanded coreceptor usage. Conclusion: These results provide in vivo evidence of SIV evolution toward RANTES resistance in macaques rapidly progressing to AIDS. RANTES resistance may represent a common virulence factor allowing primate immunodeficiency retroviruses to evade a critical mechanism of host antiviral defense.

It provides data on circulating and newly emerging strains for vaccine strain selection. To this end, antigenic characterisation by haemaggluttination inhibition (HI) assay and phylogenetic analysis was carried out on 28 EIV strains isolated in North America and Europe during 2006 and 2007. In the UK, 20 viruses were isolated from 28 nasopharyngeal swabs that tested positive by enzyme-linked immunosorbent assay. All except two of the UK viruses were characterised as members of the Florida sublineage with similarity to A/eq/Newmarket/5/03 (clade 2). One isolate, A/eq/Cheshire/1/06, was characterised as an American lineage strain similar to viruses isolated up to 10 years earlier. A second isolate, A/eq/Lincolnshire/1/07 was characterised as a member of the Florida sublineage (clade 1) with similarity to A/eq/Wisconsin/03. Furthermore. A/eq/Lincolnshire/1/06 was a member of the Florida sublineage (clade 2) by haemagglutinin (HA) gene sequence, but appeared to be a member of the Eurasian lineage by the non-structural gene (NS) sequence suggesting that reassortment had occurred. A/eq/Switzerland/P112/07 was characterised as a member of the Eurasian lineage, the first time since 2005 that isolation of a virus from this lineage has been reported. Seven viruses from North America were classified as members of the Florida sublineage (clade 1), similar to A/eq/Wisconsin/03. In conclusion, a variety of antigenically distinct EIVs continue to circulate worldwide. Florida sublineage clade 1 viruses appear to predominate in North America, clade 2 viruses in Europe.

Dimerization and fluorescence quenching has been shown to occur in concentrated aqueous solutions of various fluorophores. Here, we hypothesized that fluorophore dimerization and quenching after conjugation to targeting proteins can occur at low concentration. This dimerization can be exploited as a mechanism for fluorescence activation. Rhodamine derivatives were conjugated to avidin and trastuzumab, which target D-galactose receptor and HER2/neu antigen, respectively. After conjugation, a large proportion of R6G and TAMRA formed H-type dinners, even at low concentrations, but could be fully dequenched upon dissociation of the dinners to monomers. To demonstrate the fluorescence activation effect during in vivo fluorescence endoscopic molecular imaging, a highly quenched probe, avidin-TAMRA, or a minimally quenched probe, avidin-Alexa488, was administered into mice with ovarian metastases to the peritoneum. The tumors were clearly visualized with avidin-TAMRA, with low background fluorescence; in contrast, the background fluorescence was high for avidin-Alexa488. Thus, H-dimer formation as a mechanism of fluorescence quenching could be used to develop fluorescence activatable probes for in vivo molecular imaging.

A-type lamins have recently become the focus of extensive functional studies as a consequence of the linking of at least eight congenital diseases to mutations in the lamin A/C gene (LMNA). This spectrum of pathologies, which mostly manifest themselves as dominant traits, includes muscle dystrophies, dilated cardiomyopathies, the premature aging syndrome Hutchinson-Guilford progeria and familial partial lipodystrophy (FPLD). The crystal structure of the lamin A/C mutant R482W, a variant that causes FPLD, has been determined at 1.5 angstrom resolution. A completely novel aggregation state of the C-terminal globular domain and the position of the mutated amino-acid residue suggest means by which the mutation may affect lamin A/C-protein and protein-DNA interactions.

In the liver a major target of this sirtuin is the PPAR alpha/PGC-1 alpha signaling axis. Ablation of SIRT1 in the liver results in disrupted fatty acid oxidation, increased cellular stress, and elevations in proinflammatory cytokines. However, contrary to previous studies, we observed no changes in glucose production in the absence of SIRT1, despite impaired PGC-1 alpha signaling. These findings point toward the involvement of other players in SIRT1-regulated hepatic metabolism. Here we discuss our findings, and comment on some of the controversy surrounding this protein in the current literature.

In solitary play, children with Down syndrome showed less exploratory but similar symbolic play compared to typically developing children. From solitary to collaborative play, children with Down syndrome increased their exploratory play, attaining the same level as typically developing children. Pretense significantly increased from solitary to collaborative play only in typically developing children. Differences between mothers' play in the two groups mirrored those between their children. Both groups showed similar attunement and synchrony. Mothers contribute to the play development of children with Down syndrome through their own adaptation to their children's limitations and potentialities.

There were 1538 Framingham Heart Study participants with brain volume measures from quantitative magnetic resonance imaging who were free of stroke and other neurologic disorders that might influence brain volumes and who were members of families with at least 2 Framingham Heart Study participants. Heritability was estimated using variance component methodology and adjusting for the components of the Framingham stroke risk profile. Genetic and environmental correlations between traits were obtained from bivariate analysis. Heritability estimates ranging from 0.46 to 0.60 were observed for total brain, WMH, hippocampal, temporal lobe, and lateral ventricular volumes. Moderate, yet significant, heritability was observed for the other measures. Bivariate analyses demonstrated that relationships between brain volume measures, except for WMH, reflected both moderate to strong shared genetic and shared environmental influences. This study confirms strong genetic effects on brain and WMH volumes. These data extend current knowledge by showing that these 2 different types of magnetic resonance imaging measures do not share underlying genetic or environmental influences.

Primary care physicians are in a position to address heavy drinking and alcohol use disorders with patients, and can do so quickly and effectively. The National Institute on Alcohol Abuse and Alcoholism has published a guide for physicians that offers an evidence-based approach to screening, assessing, and treating alcohol use disorders in general health care settings. Screening can be performed by asking patients how many heavy drinking days they have per week. Assessing patients' willingness to change their drinking behaviors can guide treatment. Treatment recommendations should be presented in a clear, nonjudgmental way. Patients who are not alcohol-dependent may opt to reduce drinking to lower risk levels. Patients with alcohol dependence should receive pharmacotherapy and brief behavioral support, as well as disease management for chronic relapsing dependence. All patients with alcohol dependence should be encouraged to participate in community support groups. (Am Fam Physician. 2009; 80 (1):44-50. Copyright (C) 2009 American Academy of Family Physicians.)

TI Quantitative electrocardiographic measures and long-term mortality in exercise test patients with clinically normal resting electrocardiograms SO AMERICAN HEART JOURNAL LA English DT Article ID CORONARY-HEART-DISEASE; LEFT-VENTRICULAR HYPERTROPHY; T-WAVE ABNORMALITIES; CARDIOVASCULAR MORTALITY; ALL-CAUSE; HYPERTENSIVE PATIENTS; PREDICT MORTALITY; RISK PREDICTION; ARTERY-DISEASE; RATE RECOVERY AB Background Currently, the only function of the resting electrocardiogram (ECG) in patients referred for exercise testing is to determine whether imaging is mandated. It is unknown if subtle ECG findings in those patients with clinically normal resting ECGs have prognostic significance. Methods We performed a single-center cohort study of 18,964 patients without known cardiovascular disease who had a clinically normal resting ECG and who underwent treadmill exercise testing for evaluation of suspected coronary artery disease. Eleven quantitative ECG measures relating to heart rate, conduction, left ventricular mass, or repolarization were collected digitally. The primary outcome was all-cause mortality. The prognostic importance of a composite ECG score was assessed by measuring its impact on the c-index (analogous to area under receiver operating characteristic curve) and by measures of reclassification. Results During a median follow-up of 10.7 years, 1,585 patients died. The 4 most predictive digital ECG variables were higher ventricular rate, more leftward QRS axis, more downward ST-segment deviation, and longer QT interval. The ECG score was independently associated with mortality (75th vs 25th percentile hazard ratio 1.36, 95% confidence interval 1.25-1.49, P < .0001). The ECG score had modest impact on discrimination (change in c-index 0.04) and reclassification of risk (3.0% decrease of relative integrated discrimination improvement, P < .001). Conclusions Subtle ECG findings relating to heart rate, conduction, left ventricular mass, or repolarization in patients with clinically normal ECGs referred for exercise testing may provide modest additional prognostic information over and above clinical and exercise measures.

Our objective was to assess the impact of AF on QOL within MOST. Methods We analyzed serial QOL measures (Short Form-36, Specific Activity Scale, time trade-off) in 3 groups: (1) those without AF; (2) those with paroxysmal AF (PAF), but not chronic AF (CAF); and (3) those with CAF We carried forward the lost known QOL before crossover for all subsequent time points in patients randomized to rate modulated right ventricular pacing who crossed over to dual-chamber pacing for severe pacemaker syndrome. Results Three hundred seventeen patients (15.8%) had AF in the year after implantation, 206 patients within 3 months (191 PAF, 15 CAF), and another 159 (124 PAF, 35 CAF) between 3 and 12 months. There were no significant differences among groups in individual Short Form-36 subscales or time trade-off scores at 12 months as compared with baseline or 3 months. Cardiovascular health status was better at 12 months as compared with baseline or 3 months in those without AF. Conclusions Atrial fibrillation after pacemaker implantation in elderly patients with sick sinus syndrome was not a major determinant of QOL. However, there was a trend toward better cardiovascular functional status in patients without AF. (Am Heart J 2009;158:78-83.)

The role of glycemic control therapies, independent of their glucose-lowering effects, on cardiovascular disease is a recurring question. We examined the association of glycemic control therapies with extent of CAD as measured by coronary angiogram obtained at baseline in 1,803 subjects in the Bypass Angioplasty Revascularization Investigation 2 Diabetes (BARI 2D) trial who had type 2 diabetes mellitus, documented moderate to severe CAD, and no previous cardiac revascularization procedures. The association between glycemic control therapy use recorded at baseline and percent coronary artery stenosis and myocardial jeopardy index was analyzed by multiple regression models. Insulin use at study entry was associated with 23% fewer highly stenotic lesions (>= 70%) (p < 0.001) and a significantly lower myocardial jeopardy index compared with subjects not on insulin, despite a worse cardiac risk factor profile, more unstable angina, and increased inflammatory markers in insulin users. Subjects taking thiazolidinediones (TZDs) for >= 6 months had 17% fewer highly stenotic lesions (p = 0.02) and significantly lower C-reactive protein, fibrinogen, and plasminogen activator inhibitor-1 levels compared with those not taking TZDs. In conclusion, this cross-sectional study of patients with type 2 diabetes mellitus and CAD showed that treatment with insulin or TZDs was associated with fewer highly stenotic lesions, independent of disease duration, glycemic control, and other risk factors.

We assessed the association of 12 circulating inflammatory biomarkers (i.e., C-reactive protein, fibrinogen, interleukin-6, intercellular adhesion molecule-1, lipoprotein-associated phospholipase A2 [mass and activity], monocyte chemoattractant protein-1, myelo-peroxidase, CD40 ligand, osteoprotegerin, P-selectin, and tumor necrosis factor receptor II) with incident AF in 2863 Framingham Offspring Study participants (mean age 60.7 years, SD = 9.4, 55% women). During follow-up (median 6 years), 148 participants (43% women) developed incident AF. In the multivariable proportional hazards models, the inflammatory biomarker panel was associated with incident AF (p = 0.03). With stepwise selection (p <0.01 for entry and retention), log-transformed osteoprotegerin was associated with incident AF (hazard ratio per SD 1.30, 95% confidence interval 1.08 to 1.56, p = 0.006). Adjusting for interim myocardial infarction or heart failure attenuated the association between osteoprotegerin and incident AF (hazard ratio 1.18, 95% confidence interval 0.98 to 1.43, p = 0.09). In conclusion, circulating osteoprotegerin concentration was significantly associated with incident AF in our community-based sample, possibly mediated by interim cardiovascular events.

Objective: The purpose of this study was to develop and evaluate a scoring system for a diet screening tool to identify nutritional risk in community-dwelling older adults. Design: This cross-sectional study in older adults (n = 204) who reside in rural areas examined nutrition status by using an in-person interview, biochemical measures, and four 24-h recalls that included the use of dietary supplements. Results: The dietary screening tool was able to characterize 3 levels of nutritional risk: at risk, possible risk, and not at risk. Individuals classified as at nutritional risk had significantly lower indicators of diet quality (Healthy Eating Index and Mean Adequacy Ratio) and intakes of protein, most micronutrients, dietary fiber, fruit, and vegetables. The at-risk group had higher intakes of fats and oils and refined grains. The at-risk group also had the lowest serum vitamin B-12, folate, beta-cryptoxanthin, lutein, and zeaxanthin concentrations. The not-at-nutritional-risk group had significantly higher lycopene and beta-carotene and lower homocysteine and methylmalonic acid concentrations. Conclusion: The dietary screening tool is a simple and practical tool that can help to detect nutritional risk in older adults. Am J Clin Nutr 2009;90:177-83.

ALK+ ALCL occurs in younger patients and has a better prognosis. Human T-cell lymphotropic virus (HTLV-1) is linked to the development of adult T-cell leukemia/lymphoma (ATLL), which frequently expresses CD25. CD25 is significantly expressed in childhood ALCL. In Brazil, HTLV-1 infection is endemic, and vertical transmission is responsible for spread to children. Of HTLV-1 carriers, 90% or more remain asymptomatic. Some cases of adult HTLV-1-related lymphomas have characteristics of ALCL but are considered CD30+ ATLL subtypes. No similar cases have been described in children. We analyzed 33 cases of pediatric ALCL, CD25+ and CD25-, for proviral HTLV-1 DNA. All cases corresponded to the common histologic ALCL ope and were CD30+ in virtually all neoplastic cells. ALK expression was observed in 31 (94%) of 33 cases; CD25 was positive in 2 7 (82%), including 1 ALK- ALCL case. There was a strong positive correlation between ALK and CD25 expression. None of the cases showed proviral HTLV-1 DNA. ALCL in children has no relationship with HTLV-1; the frequent CD25 e,expression must be explained by a mechanism different from that in ATLL.

Data from the Women's Health Initiative observational study (1993-2004) were included in some analyses for additional precision. Results are presented here for incident coronary heart disease, stroke, venous thromboembolism, breast cancer, colorectal cancer, endometrial cancer, or hip fracture; death from other causes; a summary global index; total cancer; and total mortality. Hazard ratios for breast cancer and total cancer were comparatively higher (P < 0.05) among women who initiated hormone therapy soon after menopause, for both regimens. Among these women, use of conjugated equine estrogens appeared to produce elevations in venous thromboembolism and stroke and a reduction in hip fracture. Estrogen plus progestin results among women who initiated use soon after menopause were similar for venous thromboembolism, stroke, and hip fracture but also included evidence of longer-term elevations in breast cancer, total cancer, and the global index. These analyses provide little support for the hypothesis of favorable effects among women who initiate postmenopausal estrogen use soon after menopause, either for coronary heart disease or for health benefits versus risk indices considered.

The authors investigated whether the Five-Factor Model of personality traits Neuroticism, Extraversion, Openness to Experience, Agreeableness, and Conscientiousness-and trait combinations ( styles) are related to incident major or minor depression. Participants/Setting: Prospective data were gathered on a community sample of 512 older adults with disability and a history of significant health care utilization who were enrolled in a Medicare Demonstration Project. Measurements: Depression and personality traits and styles were assessed at baseline; depression was assessed again at approximately 12 and 22 months. Design: Participants who developed incident major depression were compared with those free of depression at all three assessments. Similar analyses were done for minor depression. Results: High Neuroticism and low Conscientiousness were risk factors for both major and minor depression. Combinations of high Neuroticism with low or high Extraversion or high Openness conferred risk for major depression. Other novel findings for major depression revealed new trait combinations of low Conscientiousness with low or high Extraversion, high Openness, or low Agreeableness. Three trait combinations, all involving low Conscientiousness, predicted risk for minor depression: high Neuroticism, high Agreeableness, and low Openness. Conclusion: The present findings highlight the importance of examining combinations of personality traits or personality styles when identifying those who are most at-risk for geriatric depression. Since other personality domains may modify the risk related to high Neuroticism and low Conscientiousness, the prevention, diagnosis, and treatment of depression could be greatly improved by assessing older patients not only on all five domains of personality but in terms of their combinations.

It is most commonly due to a 3.5 Mb interstitial deletion of chromosome 17 band p11.2. Secretion of melatonin, a hormone produced by the pineal gland, is the body's signal for nighttime darkness. Published reports of 24-hr melatonin secretion patterns in two independent SMS cohorts (US and France) document an inverted endogenous melatonin pattern in virtually all cases (96%), suggesting that this finding is pathognomic for the syndrome. We report on a woman with SMS due to an atypical large proximal deletion (similar to 6Mb; -TNFRSFproteinB) of chromosome band (17)(p11.2p11.2) who presents with typical sleep disturbances but a normal pattern of melatonin secretion. We further describe a melatonin light suppression test in this patient. This is the second reported patient with a normal endogenous melatonin rhythm in SMS associated with an atypical large deletion. These two patients are significant because they suggest that the sleep disturbances in SMS cannot be solely attributed to the abnormal diurnal melatonin secretion versus the normal nocturnal pattern.

Seven Turkish families segregating autosomal recessive AI (ARAI) were evaluated for evidence of a genetic etiology of AI for the seven major candidate gene loci (AMBN, AMELX, ENAM, FAM83H, KLK4, MMP20, and TUFT1). Dental and periodontal characteristics of the affected members of these families were also described. The mean scores of DMFS and dfs indices were 9.7 and 9.6, respectively. The mean PPD was 2.2 min and the percentage of the sites with plaque and BOP were 87.8% and 72.4%, respectively. The exons and intron/exon junctions of the candidate genes were sequenced and no gene mutations were identified in any individuals. These findings support the existence of an additional gene(s) that are etiologic for ARAI in these families. (C) 2009 Wiley-Liss, Inc.

It has been recognized that certain proinflammatory cytokines and coagulation factors are elevated to a greater extent in those who are frail than in age-matched nonfrail individuals. In this review, we provide an overview of current research in the biology of frailty with particular emphasis on the role of inflammatory pathways and disordered coagulation in its pathogenesis.

Several prior studies relating breastfeeding to cardiovascular risk factors have been limited by lack of adjustment for maternal and participant confounding factors. METHODS: We ascertained breastfeeding history via questionnaire from mothers enrolled in the Framingham Offspring Study. In their young to middle-aged adult children enrolled in the Framingham Third Generation, we examined the relations between maternal breastfeeding history (yes, no) and cardiovascular risk factors, including body mass index (BMI), high-density lipoprotein (HDL) cholesterol, total cholesterol, triglycerides, fasting blood glucose, and systolic and diastolic blood pressure levels. We applied generalized estimating equations to account for sibling correlations and adjusted for maternal and participant lifestyle, education, and cardiovascular risk factors. RESULTS: In Third Generation participants (n = 962, mean age = 41 years, 54% were women), 26% of their mothers reported breastfeeding. Compared with non-breastfed individuals, breastfed adult participants had lower multivariable-adjusted BMI (26.1 kg/m(2) vs 26.9 kg/m(2), P = .04) and higher HDL cholesterol levels (HDL 56.6 mg/dL vs 53.7 mg/dL, P = .01). On additional adjustment for BMI, the association between breastfeeding and HDL cholesterol was attenuated (P = .09). Breastfeeding was not associated with total cholesterol, triglycerides, fasting blood glucose, systolic blood pressure, or diastolic blood pressure. CONCLUSION: Breastfeeding in infancy is inversely associated with adult BMI and positively associated with HDL cholesterol. Associations between breastfeeding and BMI may mediate the association between breastfeeding and HDL cholesterol. (C) 2009 Elsevier Inc. All rights reserved.

We have previously demonstrated that low plasma SDF-1, a host-derived marker, increases distant metastatic risk in breast cancer. We therefore hypothesized that tumors over-expressing the SDF-1 receptor CXCR4 have an enhanced ability to metastasize in patients with low plasma SDF-1 levels. In this study, we determined the prognostic significance of activated CXCR4, or phosphorylated CXCR4 (p-CXCR4), and CXCR7, another receptor for SDF-1. immunohistochemistry was performed on a tissue microarray built using 237 samples from the same cohort of patients for which we measured plasma SDF-1 levels. We found that the prognostic value of p-CXCR4 expression (hazard ratio or HR, 3.95; P = 0.004) was superior to total CXCR4 expression (HR, 3.20; P = 0.03). The rate of breast cancer-specific mortality was much higher in patients with both high p-CXCR4 expression and low plasma SDF-1 levels (HR, 5.96; P < 0.001) than either low plasma SDF-1 (HR, 3.59; P = 0.01) or high p-CXCR4 expression (HR, 3.83; P = 0.005) alone. The added prognostic value of low plasma SDF-1 was only effective in patients with high p-CXCR4 expression, and as such, provides clinical validation for modulation of the metastatic potential of tumor cells by an inherent host-derived metastatic risk factor.

First published May 8, 2009; doi:10.1152/ajpheart.00368.2009.-Pathways that regulate mitochondrial biogenesis are potential therapeutic targets for the amelioration of endothelial dysfunction and vascular disease. Resveratrol was shown to impact mitochondrial function in skeletal muscle and the liver, but its role in mitochondrial biogenesis in endothelial cells remains poorly defined. The present study determined whether resveratrol induces mitochondrial biogenesis in cultured human coronary arterial endothelial cells (CAECs). In CAECs resveratrol increased mitochondrial mass and mitochondrial DNA content, upregulated protein expression of electron transport chain constituents, and induced mitochondrial biogenesis factors (proliferator-activated receptor-coactivator-1 alpha, nuclear respiratory factor-1, mitochondrial transcription factor A). Sirtuin 1 (SIRT1) was induced, and endothelial nitric oxide (NO) synthase (eNOS) was upregulated in a SIRT1-dependent manner. Knockdown of SIRT1 (small interfering RNA) or inhibition of NO synthesis prevented resveratrol-induced mitochondrial biogenesis. In aortas of type 2 diabetic (db/db) mice impaired mitochondrial biogenesis was normalized by chronic resveratrol treatment, showing the in vivo relevance of our findings. Resveratrol increases mitochondrial content in endothelial cells via activating SIRT1. We propose that SIRT1, via a pathway that involves the upregulation of eNOS, induces mitochondrial biogenesis. Resveratrol induced mitochondrial biogenesis in the aortas of type 2 diabetic mice, suggesting the potential for new treatment approaches targeting endothelial mitochondria in metabolic diseases.

First published May 8, 2009; doi:10.1152/ajpheart.00983.2008.-Human cytochrome P-450 (CYP)2J2 is abundant in heart and active in biosynthesis of epoxyeicosatrienoic acids (EETs). Recently, we demonstrated that these eicosanoid products protect myocardium from ischemia-reperfusion injury. The present study utilized transgenic (Tr) mice with cardiomyocyte-specific overexpression of human CYP2J2 to investigate protection toward toxicity resulting from acute (0, 5, or 15 mg/kg daily for 3 days, followed by 24-h recovery) or chronic (0, 1.5, or 3.0 mg/kg biweekly for 5 wk, followed by 2-wk recovery) doxorubicin (Dox) administration. Acute treatment resulted in marked elevations of serum lactate dehydrogenase and creatine kinase levels that were significantly greater in wild-type (WT) than CYP2J2 Tr mice. Acute treatment also resulted in less activation of stress response enzymes in CYP2J2 Tr mice (catalase 750% vs. 300% of baseline, caspase- 3 235% vs. 165% of baseline in WT vs. CYP2J2 Tr mice). Moreover, CYP2J2 Tr hearts exhibited less Dox-induced cardiomyocytes apoptosis (measured by TUNEL) compared with WT hearts. After chronic treatment, comparable decreases in body weight were observed in WT and CYP2J2 Tr mice. However, cardiac function, assessed by measurement of fractional shortening with M-mode transthoracic echocardiography, was significantly higher in CYP2J2 Tr than WT hearts after chronic Dox treatment (WT 37 +/- 2%, CYP2J2 Tr 47 +/- 1%). WT mice also had larger increases in beta-myosin heavy chain and cardiac ankryin repeat protein compared with CYP2J2 Tr mice. CYP2J2 Tr hearts had a significantly higher rate of Dox metabolism than WT hearts (2.2 +/- 0.25 vs. 1.6 +/- 0.50 ng.min(-1).100 mu g protein(-1)). In vitro data from H9c2 cells demonstrated that EETs attenuated Dox-induced mitochondrial damage. Together, these data suggest that cardiac-specific overexpression of CYP2J2 limited Dox-induced toxicity.

First published May 1, 2009; doi: 10.1152/ajplung.90626.2008.-Supplemental oxygen therapy (hyperoxia) in preterm babies with respiratory stress is associated with lung injury and the development of bronchopulmonary dysplasia. Endoplasmic reticulum (ER) homeostasis plays critical roles in maintaining cellular functions such as protein synthesis, folding, and secretion. Interruption of ER homeostasis causes ER stress and triggers the unfolded protein response, which can lead to apoptosis in persistently stressed cells. ERp57 is an ER protein and is associated with calreticulin and calnexin in protein glycosylation. In this study, we found hyperoxia downregulated ERp57 in neonatal rat lungs and cultured human endothelial cells. Transient transfection of ERp57 small interfering RNA significantly knocked down ERp57 expression and reduced hyperoxia- or tunicamycin-induced apoptosis in human endothelial cells. Apoptosis was decreased from 26.8 to 9.9% in hyperoxia-exposed cells and from 37.8 to 5.0% in tunicamycin-treated cells. The activation of caspase-3 induced by hyperoxia or tunicamycin was diminished and immunoglobulin heavy chain-binding protein/glucose-regulated protein 78-kDa (BiP/GRP78) induction was increased in ERp57 knockdown cells. Overexpression of ERp57 exacerbated hyperoxia- or tunicamycin-induced apoptosis in human endothelial cells. Apoptosis was increased from 10.1 to 14.3% in hyperoxia-exposed cells and from 14.0 to 21.2% in tunicamycin-treated cells. Overexpression of ERp57 also augmented tunicamycin-induced caspase-3 activation and reduced BiP/GRP78 induction. Our results demonstrate that ERp57 can regulate apoptosis in human endothelial cells. It appears that knockdown of ERp57 confers cellular protection against hyperoxia- or tunicamycin-induced apoptosis by inhibition of caspase-3 activation and stimulation of BiP/GRP78 induction.

TI Trends in Colorectal Cancer Test Use in the Medicare Population, 1998-2005 SO AMERICAN JOURNAL OF PREVENTIVE MEDICINE LA English DT Article ID SCREENING PROCEDURES; PREVENTIVE SERVICES; UNITED-STATES; COLON-CANCER; BENEFICIARIES; DISPARITIES; REIMBURSEMENT; COLONOSCOPY; GUIDELINES; ENROLLEES AB Background: Colorectal cancer (CRC) screening has been covered under the Medicare program since 1998. No prior study has addressed the question of the completeness of CRC screening in the entire Medicare cohort. Methods: In 2008, CRC test-use rates were analyzed for the national fee-for-service Medicare population using Medicare enrollment and claims data from 1998 through 2005. Annual test-use rates were calculated for fecal occult blood testing, sigmoidoscopy, barium enema, and colonoscopy for each year by the demographic characteristics of enrollees. A current-in-Medicare rate was calculated to assess the percentage of enrollees with CRC testing according to recommended intervals. Results: Colonoscopy rates have increased every year since the introduction of CRC screening coverage. Test-use rates for all other test modalities have steadily decreased. The percentage of Medicare enrollees receiving appropriate tests has slowly increased. In 2005, 47% of enrollees aged >= 65 years and 33% of enrollees aged 50-64 years had claims indicating that they had been tested according to recommended intervals. Conclusions: CRC test-use rates in the Medicare population are low. Disparities are apparent by age, race/ethnicity, gender, disability, income, and geographic residence. Much work remains to be done to increase testing to acceptable levels.

TI Colorectal Cancer Screening by Primary Care Physicians Recommendations and Practices, 2006-2007 SO AMERICAN JOURNAL OF PREVENTIVE MEDICINE LA English DT Article ID SERVICES TASK-FORCE; PATIENT PREFERENCES; PREVENTIVE SERVICES; NATIONAL-SURVEY; MEDICARE ENROLLEES; AMERICAN-COLLEGE; OLDER AMERICANS; UNITED-STATES; COLONOSCOPY; GUIDELINES AB Background: Primary care physicians (hereafter, physicians) play a critical role in the delivery of colorectal cancer (CRC) screening in the U.S. This study describes the CRC screening recommendations and practices of U.S. physicians and compares them to findings from a 1999-2000 national provider survey. Methods: Data from 1266 physicians responding to the 2006-2007 National Survey of Primary Care Physicians' Recommendations and Practices for Breast, Cervical, Colorectal, and Lung Cancer Screening (cooperation rate=75%) were analyzed in 2008. Descriptive statistics were used to examine physicians' CRC screening recommendations and practices as well as the office systems used to support screening activities. Sample weights were applied in the analyses to obtain national estimates. Results: Ninety-five percent of physicians routinely recommend screening colonoscopy to asymptomatic, average-risk patients; 80% recommend fecal occult blood testing (FOBT). Only a minority recommend sigmoidoscopy, double-contrast barium enema, computed tomographic colonography, or fecal DNA testing. Fifty-six percent recommend two screening modalities; 17% recommend one. Nearly all physicians who recommend endoscopy refer their patients for the procedure. Four percent perform sigmoidoscopy, a 25-percentage-point decline from 1999-2000. Although 61% of physicians reported that their practice had guidelines for CRC screening, only 30% use provider reminders; 15% use patient reminders. Conclusions: Physicians' CRC screening recommendations and practices have changed substantially since 1999-2000. Colonoscopy is now the most frequently recommended test. Most physicians do not recommend the full menu of test options prescribed in national guidelines. Few perform sigmoidoscopy. Office systems to support CRC screening are lacking in many physicians' practices. Given ongoing changes in CRC screening technologies and guidelines, the continued monitoring of physicians' CRC screening recommendations and practices is imperative.

TI Race/Ethnicity and the Perception of the Risk of Developing Prostate Cancer SO AMERICAN JOURNAL OF PREVENTIVE MEDICINE LA English DT Article ID AFRICAN-AMERICAN MEN AB Background: Although the higher risk of prostate cancer for African-American men is well known in the medical community, it is not clear how prevalent this knowledge is among African-American men themselves. Both the side effects of treatment and the lack of a demonstrated mortality benefit of routine screening with the prostate-specific antigen test among men in the general population have increased the focus on patient participation in decision making about prostate cancer screening. Methods: Data on 1075 male respondents to the 2003 Health Information National Trends Study were collected from October 2002 to April 2003 and analyzed in 2008 to examine the associations among race/ethnicity, demographic characteristics, and the perception of the risk of developing prostate cancer for African-American, Hispanic, and non-Hispanic white men aged >= 45 years without a history of prostate cancer. Results: Nearly 50% of African-American men, 47.4% of Hispanic men, and 43.3% of non-Hispanic white men perceived their likelihood of getting prostate cancer as somewhat or very low. Nearly 18% of African-American men, 21.6% of Hispanic men, and 12.9% of non-Hispanic white men perceived themselves to be more likely to get prostate cancer than the average man of the same age. Conclusions: Despite statistics to the contrary, few African-American men perceived themselves to have a higher-than-average risk of prostate cancer, while a higher percentage of Hispanic men perceived their risk to be higher than that of the average man of the same age. These findings suggest that all men, but particularly African-American and Hispanic men, could benefit from information regarding their specific risk of developing prostate cancer before making a decision about prostate cancer screening.

TI Glucocorticoid- and Protein Kinase A-Dependent Transcriptome Regulation in Airway Smooth Muscle SO AMERICAN JOURNAL OF RESPIRATORY CELL AND MOLECULAR BIOLOGY LA English DT Article DE airway smooth muscle; protein kinase A; glucocorticoid; gene expression; G protein-coupled receptors ID GENE-EXPRESSION; CELL-PROLIFERATION; EXTRACELLULAR-MATRIX; COUPLED RECEPTORS; OLIGONUCLEOTIDE ARRAYS; ASTHMA; CAMP; DEXAMETHASONE; GROWTH; ACTIVATION AB Glucocorticoids (GCs) and protein kinase A (PKA)-activating agents (beta-adrenergic receptor agonists) are mainstream asthma therapies based on their ability to prevent or reverse excessive airway smooth muscle (ASM) constriction. Their abilities to regulate another important feature of asthma-excessive ASM growth-are poorly understood. Recent studies have suggested that GCs render agents of inflammation such as IL-1 beta and TNF-alpha mitogenic to ASM, via suppression of (antimitogenic) induced cyclooxygenase-2-dependent PKA activity. To further explore the mechanistic basis of these observations, we assessed the effects of epidermal growth factor and IL-1 beta stimulation, and the modulatory effects of GC treatment and PKA inhibition, on the ASM transcriptome by microarray analysis. Results demonstrate that ASM stimulated with IL-1 beta, in a manner that is often cooperative with stimulation with epidermal growth factor, exhibit a profound capacity to function as immunomodulatory cells. Moreover, results implicate an important role for induced autocrine/paracrine factors (many whose regulation was minimally affected by GCs or PKA inhibition) as regulators of both airway inflammation and ASM growth. Induction of numerous chemokines, in conjunction with regulation of proteases and agents of extracellular matrix remodeling, is suggested as an important mechanism promoting upregulated G protein-coupled receptor signaling capable of stimulating ASM growth. Additional functional assays suggest that intracellular PKA plays a critical role in suppressing the promitogenic effects of induced autocrine factors in ASM. Finally, identification and comparison of GC- and PKA-sensitive genes in ASM provide insight into the complementary effects of beta-agonist/GC combination therapies, and suggest specific genes as important targets for guiding the development of new generations of GCs and adjunct asthma therapies.

The mission of the National Institutes of Health Office of Dietary Supplements is to support and promote the science on the benefits and risks of dietary supplements. To this end, Office of Dietary Supplements supports a number of initiatives to advance the evidence base on vitamin D. These initiatives include an evidence-based review on the relationship of vitamin D and calcium intakes to nutrient status indicators and health outcomes; developing and validating analytical methods for measuring vitamin D in biological fluids and foods; support for continued collection of vitamin D status indicators through the National Health and Nutrition Examination Survey; and funding for National Institutes of Health grants on vitamin D and related health outcomes. Taken together, these programs address research gaps and needs to further the science and exploration of the role of vitamin D in health. C1 NIH, Off Dietary Supplements, Bethesda, MD 20892 USA.

Although obesity and drug addiction are typically considered distinct clinical entities, both diseases involve dysregulation of biogenic amine neuron systems in the brain. Thus, research efforts to develop medications for treating drug addiction can contribute insights into the pharmacotherapy for obesity. Here, we review the neurochemical mechanisms of selected stimulant medications used in the treatment of obesity and issues related to fenfluramine-associated cardiac valvulopathy. In particular, we discuss the evidence that cardiac valve disease involves activation of mitogenic serotonin 213 (5-HT(2B)) receptors by norfenfluramine, the major metabolite of fenfluramine. Advances in medication discovery suggest that novel molecular entities that target 2 different neurochemical mechanisms, that is, "combination pharmacotherapy," will yield efficacious antiobesity medications with reduced adverse side effects.

Small molecule chaperones that bind to enzyme proteins and correct the misfolding and mistrafficking of mutant proteins have emerged as a new therapeutic approach for the lysosomal storage disorders. In addition, alpha-glucosidase is a therapeutic target for type II diabetes, and alpha-glucosidase inhibitors have been used in the clinic as alternative treatments for this disease. We have developed a new fluorogenic substrate for the alpha-glucosidase enzyme assay, resorufin alpha-D-glucopyranoside. The enzyme reaction product of this new Substrate emits at a peak of 590 nm, reducing the interference from fluorescent compounds seen with the existing fluorogenic substrate, 4-methylumbelliferyl-alpha-D-glucopyranoside. Also, the enzyme kinetic assay can be carried out continuously without the addition Of Stop Solution due to the lower pK(a) of the product of this substrate. Therefore, this new fluorogenic substrate is a useful tool for the alpha-glucosidase enzyme assay and will facilitate compound screening for the development of new therapies for Pompe disease.

TI Impact of Gene Copy Number Variation on Anesthesia in Drosophila melanogaster SO ANESTHESIOLOGY LA English DT Article ID CATION CHANNEL; GENOME; MUTATIONS; POLYMORPHISM; NUCLEOTIDE; SELECTION; VARIANTS; REVEAL; REGION AB Background Chromosomal deletions and duplications, which result in halving or doubling of copy number in a block of genes, are an important source of variation between Individuals. Phenotypic effects of copy number variation are commonly observed, but effects on sensitivity to volatile anesthetics have not been assessed in any organism. Methods: The potency with which halothane depresses the righting reflex of fruit flies was measured in congenic Drosophila strains, each of which was heterozygous for a deletion of average size 400 kb. Over 200 strains were examined, thereby scanning approximately half of the fly genome. Results: Although the vast majority of deletion heterozygotes were indistinguishable from the control, eight had significantly altered sensitivity to halothane. Genetic tests supported the hypothesis that the change in anesthetic sensitivity was the result of reduction in copy number and not adventitious mutations in the strains. Among the eight outliers, the difference in halothane potency ranged from a 25% increase to a 15% decrease. Changes of similar magnitude but distinctive patterns were found when these lines were tested with enflurane, isoflurane, and sevoflurane. Conclusions: Variation in gene copy number has a significant Impact on anesthetic sensitivity in Drosophila melanogaster. The level of transcription of a few genes must thus be limiting for a normal response to volatiles. Coupling between gene copy and gene expression is universal, and the components of the fly's nervous system are highly conserved, therefore, this work provides a rationale for investigating the clinical impact of copy number variation.

In most cases, T cell-mediated immune destruction of hematopoietic cells results in peripheral blood pancytopenia and bone marrow hypoplasia. A subset of the heterodimeric interleukin-23 receptor gene (IL-23R) is significantly associated with autoimmune-mediated diseases. To examine whether IL-23R single nucleotide polymorphisms (SNPs) might contribute to AA, we selected three IL-23R SNPs with amino acid changes (rs11209026: p.Arg381Gln; rs41313262: p.Val362Ile; and rs11465797: p.Thr175Asn) and compared their frequencies in 279 AA patients and 184 ethnically matched healthy controls. The three SNP prevalences were similar between the AA patients and controls. The Arg381Gln variant, which has a strong protective effect against inflammatory bowel disease, showed no association with AA. Furthermore, IL-23 levels in sera were measured in the AA patients and in controls, and there were no significant differences among them. Our results indicate that these three IL-23R SNPs and serum IL-23 level have no apparent impact on susceptibility to AA.

We investigated variation throughout LRRK2 (84 SNPs; genotype or diplotype found for 49 LD blocks) for 275 cases (European ancestry, onset at age 60 or older) and 275 neurologically healthy control subjects (NINDS Neurogenetics Repository). Three grade-of-membership groups, i.e. genetic risk sets, were identified that exactly matched many subjects (cases: 46, 4, 137; controls: 0, 178, 0), and distinguished 94% of the subjects (i.e. > 50% likeness to one set). Set I, affected, carried certain low frequency alleles located in multiple functional domains. Set II was unaffected. Set III, also affected, resembled set II except for slightly elevated frequencies of minor alleles not defining set I. We conclude that certain low frequency alleles distributed throughout LRRK2 are a genetic background to a third of cases, defining a distinct subset.

Eight human genes are described resulting in the HPS subtypes 1-8. Certain HPS proteins combine to form Biogenesis of Lysosome-related Organelles Complexes (BLOCs), thought to function in the formation of intracellular vesicles such as melanosomes, platelet dense bodies, and lytic granules. Specifically, BLOC-2 contains the HPS3, HPS5 and HPS6 proteins. We used phylogenetic footprinting to identify conserved regions in the upstream sequences of HPS3, HPS5 and HPS6. These conserved regions were verified to have in vitro transcription activation activity using luciferase reporter assays. Transcription factor binding site analyses of the regions identified 52 putative sites shared by all three genes. When analysis was limited to the conserved footprints, seven binding sites were found shared among all three genes: Pax-5, AIRE, CACD, ZF5, Zic1, E2F and Churchill. The HPS3 conserved upstream region was sequenced in four patients with decreased fibroblast HPS3 RNA levels and only one HPS3 mutation in the coding exons and surrounding exon/intron boundaries; no mutation was found. These findings illustrate the power of phylogenetic footprinting for identifying potential regulatory regions in non-coding sequences and define the first putative promoter elements for any HPS genes.

The classic question when looking into the genetic variations in a population is whether the population is in the state of Hardy-Weinberg Equilibrium (HWE). Our objective was to develop test procedures using family data from complex surveys such as NHANES III. We developed six Pearson chi(2) based tests for a diallelic locus of autosomal genes. The finite sample properties of the proposed test procedures were evaluated via Monte Carlo simulation studies and the Rao-Scott first order corrected test was recommended. Test procedures were applied to three loci from NHANES III genetic databases, i.e., ADRB2, TGFB1, and VDR. HWE was shown to hold at 0.05 level for all three loci when only families with genotypic information available for two parents and for one or more children were used in the analysis.

Methods: We conducted a cohort study based on the Swedish Multi-Generation Register in 1961 to 2005. Among 6,671 probands (first ALS case in the family), 1,909 full siblings, 13,947 children, and 5,405 spouses were identified (exposed group). Other persons in the Multi-Generation Register, who were siblings, children, or spouses to persons without ALS, served as the reference group. Relative risks for ALS among the exposed group, compared with the reference group, were calculated from Poisson regression models. Concurrence of ALS within twins was assessed in 86,441 twin pairs registered in the Swedish Twin Register. Results: Nine cases of ALS were noted among the siblings and 37 cases among the children of the probands, giving a 17-fold risk among the siblings (95% confidence interval, 8.1-30.4) and a 9-fold risk among the children (95% confidence interval, 6.2-12.0), compared with the reference group. Siblings and children had a greater excess risk if the proband was diagnosed at a younger age, and the excess risks decreased with increasing age at diagnosis of the proband (p < 0.001). Spouses had no significantly increased risk (p = 0.27). Two cases were identified among the cotwins of ALS probands, giving a relative risk of 32 (95% confidence interval, 5.2-102.6). Interpretation: The siblings and children of ALS patients have an about 10-fold risk for ALS compared with the reference group. The excess risks vary with both age and kinship, indicating a major genetic role in familial ALS.

DATA SOURCES: A MEDLINE search (1968-November 2008) of the English-language literature was performed using the terms continuous infusion and Pseudomonas or Acinetobacter, hemofiltration or CVVH or hemodiafiltration or CVVHDF or continuous renal replacement therapy or pharmacokinetics; and terms describing different beta-lactam antibiotics. STUDY SELECTION AND DATA EXTRACTION: In vitro, in vivo, and human studies were evaluated that used continuous-infusion beta-lactam antibiotics to treat Pseudomonas aeruginosa and Acinetobacter baumannii infections. Studies were reviewed that described the pharmacokinetics of beta-lactam antibiotics during CVVH as well as other modalities of continuous renal replacement therapy. DATA SYNTHESIS: Continuous infusion of beta-lactam antibiotics, maintaining drug concentrations 4-5 times higher than the minimum inhibitory concentration, is a promising approach for managing infections caused by P. aeruginosa and A. baumannii. Safe yet effective continuous infusion therapy is made difficult by the occurrence of acute renal failure and the need for renal replacement therapy. Case series and pharmacokinetic properties indicate that several beta-lactam antimicrobials that have been studied for continuous infusion, such as cefepime, ceftazidime, piperacillin, ticarcillin, clavulanic acid, and tazobactam, are significantly cleared by hemofiltration. Methodology and formulas are provided that allow practitioners to calculate dosage regimens and reach target drug concentrations for continuous beta-lactam antibiotic infusions during CVVH based on a literature review, pharmacokinetic principles, and our experience at the National Institutes of Health Clinical Center. CONCLUSIONS: Continuous infusion of beta-lactam antibiotics may be a useful treatment strategy for multidrug-resistant gram-negative infections in the intensive care unit. Well-established pharmacokinetic and pharmacodynamic principles can be used to safely reach and maintain steady-state target concentrations of beta-lactam antibiotics in critical illness complicated by acute renal failure requiring CVVH.

From June 1994 through July 2005, 120 patients with unresectable CRC LM underwent IHP with melphalan (n = 69), tumor necrosis factor (TNF) (n = 10) or both (n = 41). Hepatic arterial infusion (HAI) with floxuridine started 6-8 weeks post IHP in 46 (38%). Patients were followed for toxicity, radiographic response, and overall survival (OS). Wilcoxon rank-sum and Fisher's exact tests were used to compare parameters by response category; survival and hepatic progression-free survival were calculated by the Kaplan-Meier method. Of 79 males and 41 females, 96 (80%) received prior chemotherapy. There were five (4%) operative/treatment mortalities. There were 69 responses in 114 evaluable patients (61%). Total melphalan dose and combination melphalan/TNF were each associated with response; age, preoperative carcinoembryonic antigen (CEA), prior chemotherapy for established LM, tumor burden, and post-IHP HAI therapy were not. Median overall survival was 17.4 months and 2-year survival was 34%. Factors found to be independently related to survival were preoperative CEA < 30 ng/mL and use of post-IHP HAI (P < 0.015). IHP results in marked tumor regression and prolonged survival in patients with CRC LM. Continued development of IHP in this clinical setting is warranted. C1 [Alexander, H.

Patients and Methods: A total of 108 patients with clinical early endometrioid grade I or II endometrial carcinoma underwent complete pelvic lymphadenectomy between 2001-2007. Only cases with at least 15 nodes histologically examined were included. All operations were performed by the same team. The preoperative tumor histology was compared with the final pathological findings. The incidence of pelvic nodal involvement was estimated in relation to the final grade and depth of myometrial invasion in halves. Results: The median age of patients was 63 years. In the final histology, 10 tumors (9.3%) of non-endometrioid histology were found. The discordance between pre- and postoperative tumor grade was 32.4%, with 24.1% being upgraded. Nine patients (8.3%) had poorly differentiated tumors and 23 (21.3%) deep (>50%) myometrial invasion in the final pathology. A total of 11 patients (10.2%) had pelvic nodal metastasis. The rate of lymph node metastasis in relation to final grade I and II and myometrial invasion was as follows: grade 1, 1.8% (inner half 0%, outer half 14.3%); grade 11, 15.9% (inner half 12.1% outer half 27.3%). Overall 19.4% of patients were upstaged at surgery. Conclusion: A significant proportion of patients presenting with early endometrial cancer of optimal characteristics will have a more advanced disease at surgical staging. Complete pelvic lymphadenectomy may increase the possibility of detecting metastatic disease in the lymph nodes.

TI Heteroresistance to Fluconazole in Cryptococcus neoformans Is Intrinsic and Associated with Virulence SO ANTIMICROBIAL AGENTS AND CHEMOTHERAPY LA English DT Article ID RESISTANT CANDIDA-ALBICANS; DRUG-RESISTANCE; AZOLE RESISTANCE; ITRACONAZOLE RESISTANCE; ASPERGILLUS-FUMIGATUS; ANTIFUNGAL AGENTS; PETITE MUTANTS; IN-VIVO; MECHANISMS; AIDS AB In 1999, heteroresistance to triazoles was reported in Cryptococcus neoformans strains isolated from an azole therapy failure case of cryptococcosis in an AIDS patient and in a diagnostic strain from a non-AIDS patient. In this study, we analyzed 130 strains of C. neoformans isolated from clinical and environmental sources before 1979, prior to the advent of triazoles, and 16 fluconazole (FLC)-resistant strains isolated from AIDS patients undergoing FLC maintenance therapy during 1990 to 2000. All strains isolated prior to 1979 manifested heteroresistance (subset of a population that grows in the presence of FLC) at concentrations between 4 and 64 mu g/ml, and all 16 FLC-resistant AIDS isolates manifested heteroresistance at concentrations between 16 and 128 mu g/ml. Upon exposure to stepwise increases in the concentration of FLC, subpopulations that could grow at higher concentrations emerged. Repeated transfer on drug-free media caused the highly resistant subpopulations to revert to the original level of heteroresistance. The reversion pattern fell into four categories based on the number of transfers required. The strains heteroresistant at >= 32 mu g/ml were significantly more resistant to other xenobiotics and were also more virulent in mice than were those heteroresistant at <= 8 mu g/ml. During FLC treatment of mice infected by strains with low levels of heteroresistance, subpopulations exhibiting higher levels of heteroresistance emerged after a certain period of time. The ABC transporter AFR1, known to efflux FLC, was unrelated to the heteroresistance mechanism. Our study showed that heteroresistance to azole is universal and suggests that heteroresistance contributes to relapse of cryptococcosis during azole maintenance therapy.

Deferasirox was administered for an average of 14 days (range, 7 to 21) at 5 to 20 mg/kg of body weight/day. The only adverse effects attributable to deferasirox were rashes in two patients. Deferasirox treatment was not associated with changes in renal or liver function, complete blood count, or transplant immunosuppressive levels. Thus, deferasirox appears safe as an adjunctive therapy for mucormycosis.

The rationale was to determine whether physical interactions between the enzyme and mitochondria were linked to the axonopathy of motor fibers occurring in amyotrophic lateral sclerosis (ALS). Mitochondria and SOD1 displayed a homogeneous distribution along motor axons both in nontransgenic rats and in those overexpressing wild-type SOD1. In contrast, axons from SOD1-G93A rats (older than 35 days) showed accumulation of mitochondria in discrete clusters located at regular intervals. Most of SOD1 immunoreactivity was enriched in these clusters and colocalized with mitochondria, suggesting a recruitment of SOD1-G93A to the organelle. The SOD1/mitochondrial clusters were abundant in motor axons but scarcely seen in sensory axons. Clusters also were stained for neuronal nitric oxide synthase, nitrotyrosine, and cytochrome c. The later also was detected surrounding clusters. Ubiquitin colocalized with clusters only at late stages of the disease. The cytoskeleton was not overtly altered in clusters. These results suggest that mutant SOD1 and defective mitochondria create localized dysfunctional domains in motor axons, which may lead to progressive axonopathy in ALS. Antioxid.

The vast majority of the available information on this topic focuses on respiratory syncytial virus (RSV: Family Paramyxoviridae, genus Pneumovirus), an important pediatric pathogen that infects infants worldwide. There is no vaccine currently available for RSV. A formalin-inactivated RSV vaccine used in a trial in the 1960s elicited immunopathology in response to natural RSV infection: this has been modeled experimentally, primarily in inbred mice and cotton rats. Eosinophils are recruited to the lung tissue in response to formalin-inactivated RSV vaccine antigens in humans and in experimental models. but they may or may not be involved in promoting the severe clinical sequelae observed. Pulmonary eosinophilia elicited in response to primary RSV infection has also been explored: this response is particularly evident in the youngest human infants and in neonatal mouse models. Although pulmonary eosinophilia is nearly always perceived in a negative light, the specific role played by virus-elicited eosinophils - negative, positive or neutral bystander - remain unclear. Lastly, we consider the data that focus on the role of eosinophils in promoting virus clearance and antiviral host defense, and conclude with a recent study that explores the role of eosinophils themselves as targets of virus infection.

High-throughput genomics methods are now being used to identify the biochemical pathways underlying ineffective or damaging host responses in a number of acute and chronic viral infections. This article reviews recent gene expression studies of 1918 H1N1 influenza and Ebola hemorrhagic fever in cell culture and animal models, focusing on how genomics experiments can be used to increase our understanding of the mechanisms that permit those viruses to cause rapidly overwhelming infection. Particular attention is paid to how evasion of type I IFN responses in infected cells might contribute to over-activation of inflammatory responses. Reviewing recent research and describing how future studies might be tailored to understand the relationship between the infected cell and its environment, this article discusses how the rapidly growing field of high-throughput genomics can contribute to a more complete understanding of severe, acute viral infections and identify novel targets for therapeutic intervention.

One of the anaplastic large cell lymphoma cases was found surrounding a silicone breast implant and presented as clinically as mastitis; whereas the other case occurred in a man. T-cell lymphoma secondarily involved the breast in 7 patients, all women and 1 bilateral, with a median age of 29 years. These secondary breast lymphomas occurred as part of widespread nodal or leukemic disease. Three patients had adult T-cell leukemia/lymphoma, including the patient with bilateral lesions, 3 others had precursor T-lymphoblastic lymphoma/leukemia, and the other presented with a peripheral-T-cell lymphoma nonotherwise specified type.

It is well established that genetic factors play a major role in the development of this disorder. Identification of genes that contribute to alcohol dependence will improve our understanding of the mechanisms that underlie this disorder. Objective: To identify susceptibility genes for alcohol dependence through a genome-wide association study (GWAS) and a follow-up study in a population of German male inpatients with an early age at onset. Design: The GWAS tested 524 396 single-nucleotide polymorphisms (SNPs). All SNPs with P < 10(-4) were subjected to the follow-up study. In addition, nominally significant SNPs from genes that had also shown expression changes in rat brains after long-term alcohol consumption were selected for the follow-up step. Setting: Five university hospitals in southern and central Germany. Participants: The GWAS included 487 male inpatients with alcohol dependence as defined by the DSM-IV and an age at onset younger than 28 years and 1358 population-based control individuals. The follow-up study included 1024 male inpatients and 996 age-matched male controls. All the participants were of German descent. Main Outcome Measures: Significant association findings in the GWAS and follow-up study with the same alleles. Results: The GWAS produced 121 SNPs with nominal P < 10(-4). These, together with 19 additional SNPs from homologues of rat genes showing differential expression, were genotyped in the follow-up sample. Fifteen SNPs showed significant association with the same allele as in the GWAS. In the combined analysis, 2 closely linked intergenic SNPs met genome-wide significance (rs7590720, P=9.72 X 10(-9); rs1344694, P=1.69 X 10(-8)). They are located on chromosome region 2q35, which has been implicated in linkage studies for alcohol phenotypes. Nine SNPs were located in genes, including the CDH13 and ADH1C genes, that have been reported to be associated with alcohol dependence. Conclusions: This is the first GWAS and follow-up study to identify a genome-wide significant association in alcohol dependence. Further independent studies are required to confirm these findings.

TI Increased Prevalence of Autoimmunity in Patients With White Spot Syndromes and Their Family Members SO ARCHIVES OF OPHTHALMOLOGY LA English DT Article ID PLACOID PIGMENT EPITHELIOPATHY; JUVENILE RHEUMATOID-ARTHRITIS; OCCULT OUTER RETINOPATHY; MULTIPLE-SCLEROSIS; MULTIFOCAL CHOROIDITIS; GENETIC-ANALYSIS; CROHNS-DISEASE; GRANULOMATOSIS; CHOROIDOPATHY; ASSOCIATION AB Objective: To determine whether there is an increased prevalence of systemic autoimmune diseases in both patients with white spot syndromes (WSS) and their family members. Methods: Patients with WSS at participating institutions were asked to complete a questionnaire reporting their own medical histories as well as any autoimmune diseases among their first-and second-degree relatives. Results: As of January 1, 2008, 114 questionnaires had been collected, providing medical histories of 114 patients with WSS and 1098 family members. The number of patients with WSS with self-reported systemic autoimmune diseases was 26 (23%). Of 1098 relatives, 106 (10%) had at least 1 autoimmune disease. Systemic autoimmunity was more prevalent in female relatives (13%) as compared with male relatives (6%). In addition, the prevalence of autoimmunity was significantly higher among first-degree relatives (13%) than second-degree relatives (8%). Patients who themselves had systemic autoimmune diseases showed a greater prevalence of systemic autoimmunity among their families as compared with the families of patients without systemic autoimmune diseases. Conclusions: Our data indicate that there is an increased prevalence of systemic autoimmunity in both patients with WSS and their first-and second-degree relatives. This suggests that WSS occur in families with inherited immune dysregulation that predisposes to autoimmunity.

Design: Prospective cohort survey. Setting: National Institutes of Health Clinical Center, a federal biomedical research facility. Patients: The study population comprised 80 individuals, aged 1.5 to 59 years, ascertained on the basis of EVA and sensorineural hearing loss. Main Outcome Measures: Associations among the number of mutant alleles of SLC26A4; volume and texture of the thyroid; percentage of iodine 123 (123I) discharged at 120 minutes after administration of perchlorate in the perchlorate discharge test; and peripheral venous blood levels of thyrotropin, thyroxine, free thyroxine, triiodothyronine, thyroglobulin, antithyroid peroxidase and antithyroglobulin antibodies, and thyroid-binding globulin. Results: Thyroid volume is primarily genotype dependent in pediatric patients but age dependent in older patients. Individuals with 2 mutant SLC26A4 alleles discharged a significantly (P <= .001) greater percentage of (123)I compared with those with no mutant alleles or 1 mutant allele. Thyroid function, as measured by serologic testing, is not associated with the number of mutant alleles. Conclusions: Ultrasonography with measurement of gland volume is recommended for initial assessment and follow-up surveillance of the thyroid in patients with EVA. Perchlorate discharge testing is recommended for the diagnostic evaluation of patients with EVA along with goiter, nondiagnostic SLC26A4 genotypes (zero or 1 mutant allele), or both.

Objective: To examine motor unit characteristics (size and firing rate) associated with aging. Design: Cross-sectional, observational. Setting: Community. Participants: Baltimore Longitudinal Study of Aging participants (N=102), aged 22.2 to 94.1 years, were studied. Interventions: Not applicable. Main Outcome Measures: Surface-represented motor unit size and firing rate were collected from the vastus medialis during knee extension at 10%, 20%, 30%, and 50% of each subject's maximum isometric voluntary contraction (MVC). Results: MVC declined with older age (P<.0001). Adjusting for differences in MVC, both firing rate and motor unit size per newton force generated began to increase in the 6th decade of life. Motor unit size increased per newton force to a greater extent than firing rate. Those over the age of 75 years also activated significantly larger motor units per unit force (P=.04). Relative to force generated, the average firing rate began increasing at 57.8 +/- 3.4 years and between 50.2 and 56.4 years (+/- 4y) for motor unit size. Conclusions: The size of motor units and firing rates used to achieve a given force changes with age, particularly after middle age. Whether these changes precede, follow, or occur concurrent to age-related modifications in muscle structure and contractile properties or sarcopenia is not known.

Since the testes are one of the most sensitive organs to acute Cd toxicity, we examined possible strain-related differences in Cd-induced testicular toxicity between inbred WI and F344 rats. Rats were treated with a single dose of 0.5, 1.0 or 2.0 mg Cd/kg, as CdCl(2), sc and killed 24 h later. Cd at doses of 1.0 and 2.0 mg/kg induced severe testicular hemorrhage, as assessed by pathological and testis hemoglobin content, in F344 rats, but not WI rats. After Cd treatment (2.0 mg/kg), the testicular Cd content was significantly lower in WI rats than in the F344 rats, indicating a toxiokinetic mechanism for the observed strain difference. Thus, the remarkable resistance to Cd-induced testicular toxicity in WI rats is associated, at least in part, with lower testicular accumulation of Cd. When zinc (Zn; 10 mg/kg, sc) was administered in combination with Cd (2.0 mg/kg) to F344 rats, the Cd-induced increase in testicular hemoglobin content, indicative of hemorrhage, was significantly reduced. Similarly, the testicular Cd content was significantly decreased with Zn co-treatment compared to Cd treatment alone. Thus, it can be concluded that the testicular Cd accumulation partly competes with Zn transport systems and that these systems may play an important role in the strain-related differences in Cd-induced testicular toxicity between WI and F344 rats.

However, it is critical to determine whether SARS-CoV-specific memory T cells can persist for long periods of time. In this study, we analyzed the cellular immune response from 21 SARS-recovered individuals who had been diagnosed with SARS in 2003 by using ELISA, CBA, ELISpot and multiparameter flow cytometry assays. Our results demonstrated that low levels of specific memory T cell responses to SARS-CoV S, M, E and N peptides were detected in a proportion of SARS-recovered patients, and IFN-gamma was the predominant cytokine produced by T cells after stimulation with peptides. Cytometry analysis indicated that the majority of memory CD8(+) T cells produced IFN-gamma, whereas memory CD4(+) T cells produced IFN-gamma, IL-2 or TNF-alpha. These results might provide valuable information on the cellular immune response in recovered SARS-CoV patients for the rational design of vaccines against SARS-CoV infection.

We investigated the association of serum resistin concentrations with risk for incident heart failure (HF) in humans. Methods and Results-We studied 2902 older persons without prevalent HF (age, 73.6 +/- 2.9 years; 48.1% men; 58.8% white) enrolled in the Health, Aging, and Body Composition (Health ABC) Study. Correlation between baseline serum resistin concentrations (20.3 +/- 10.0 ng/mL) and clinical variables, biochemistry panel, markers of inflammation and insulin resistance, adipocytokines, and measures of adiposity was weak (all rho <0.25). During a median follow-up of 9.4 years, 341 participants (11.8%) developed HF. Resistin was strongly associated with risk for incident HF in Cox proportional hazards models controlling for clinical variables, biomarkers, and measures of adiposity (HR, 1.15 per 10.0 ng/mL in adjusted model; 95% CI, 1.05 to 1.27; P = 0.003). Results were comparable across sex, race, diabetes mellitus, and prevalent and incident coronary heart disease subgroups. In participants with available left ventricular ejection fraction at HF diagnosis (265 of 341; 77.7%), association of resistin with HF risk was comparable for cases with reduced versus preserved ejection fraction. Conclusions-Serum resistin concentrations are independently associated with risk for incident HF in older persons. (Arterioscler Thromb Vasc Biol. 2009; 29: 1144-1149.)

Using a combination of clinical, radiographic, functional, and serum protein biomarker assessments, this study was aimed at defining the prevalence and clinical characteristics of interstitial lung disease (ILD) in a large cohort of patients with anti-Jo-1 antibodies. Methods. A review of clinical records, pulmonary function test results, and findings on imaging studies determined the existence of ILD in anti-Jo-1 antibody-positive individuals whose data were accumulated in the University of Pittsburgh Myositis Database from 1982 to 2007. Multiplex enzyme-linked immunosorbent assays (ELISAs) for serum inflammation markers, cytokines, chemokines, and matrix metalloproteinases in different patient subgroups were performed to assess the serum proteins associated with anti-Jo-1. antibody-positive ILD. Results. Among the 90 anti-Jo-1 antibody-positive individuals with sufficient clinical, radiographic, and/or pulmonary function data, 77 (86%) met the criteria for ILD. While computed tomography scans revealed a variety of patterns suggestive of underlying usual interstitial pneumonia (UIP) or nonspecific interstitial pneumonia, a review of the histopathologic abnormalities in a subset of patients undergoing open lung biopsy or transplantation or whose lung tissue was obtained at autopsy (n = 22) demonstrated a preponderance of UIP and diffuse alveolar damage. Analysis by multiplex ELISA yielded statistically significant associations between anti-Jo-1 antibody-positive ILD and elevated serum levels of C-reactive protein (CRP), CXCL9, and CXCL10, which distinguished this disease entity from idiopathic pulmonary fibrosis and anti-signal recognition particle antibody-positive myositis. Recursive partitioning further demonstrated that combinations of these and other serum protein biomarkers can distinguish these disease subgroups at high levels of sensitivity and specificity. Conclusion. In this large cohort of anti-Jo-1 antibody-positive individuals, the incidence of ILD approached 90%. Multiplex ELISA demonstrated disease-specific associations between anti-Jo-1 antibody-positive ILD and serum levels of CRP as well as the interferon-gamma-inducible chemokines CXCL9 and CXCL10, highlighting the potential of this approach to define biologically active molecules contributing to the pathogenesis of myositis-associated ILD.

Household indoor air pollution concentrations were measured during unvented burning (chimneys blocked) and vented burning (chimneys open) of bituminous coal in Xuan Wei, China. Concentrations of particulate matter with an aerodynamic diameter of 10 mu m or less (PM10) and of benzo[a]pyrene (BaP) were measured in 43 homes during normal activities. The use of chimneys led to significant decreases in indoor air concentrations of particulate matter with an aerodynamic diameter of 10 mu m or less (PM10) by 66% and of benzo[a]pyrene (BaP) by 84%. The average BaP content of PM10 also decreased by 55% with the installation of a chimney. The reduction of indoor pollution levels by the installation of a chimney supports the epidemiology findings on the health benefits of stove improvement. However, even in the presence of a chimney, the indoor air concentrations for both PM10 and BaP still exceeded the indoor air quality standards of China. Movement up the energy ladder to cleaner liquid or gaseous fuels is probably the only sustainable indoor air pollution control measure. (C) 2009 Elsevier Ltd. All rights reserved.

We surveyed toxin concentrations in various tissues of Hooded Pitohui (Pitohui dichrous) using radioligand binding assays. The highest concentrations were found in the skin and feathers, on the outside of the birds, where predators or parasites are likely to encounter toxins. Significant levels of toxins also were found in skeletal muscle, heart, and liver. Muscle and liver would normally be poisoned by batrachotoxins; thus, Hooded Pitohuis must be insensitive to the toxins. The presence of toxins in internal organs further argues against the hypothesis that Hooded Pitohuis merely apply toxins topically to skin and feathers. Finally, we used scanning and transmission electron microscopy to examine skin and feathers for unusual morphological or histological adaptations for storing and secreting toxins. The skin of Hooded Pitohuis appears to have typical dermal and epidermal morphology, and we speculate on possible ways in which this species may sequester and secrete toxins using typical avian skin structural features, unique among vertebrates.

Although Parkin is primarily cytosolic, we have found that Parkin is selectively recruited to dysfunctional mitochondria with low membrane potential and subsequently promotes their autophagy. Here we report that Parkin recruitment is voltage-dependent and independent of changes in ATP or pH. These findings suggest that Parkin promotes mitophagy of dysfunctional mitochondria following loss of mitochondrial membrane potential and implicates the targeted elimination of mitochondria in the pathogenesis of Parkinson disease.

TI The values and limits of an in vitro model of Pompe disease The best laid schemes o' mice an' men ... SO AUTOPHAGY LA English DT Editorial Material DE lysosomal storage; glycogen; Pompe disease; myotubes; Atg7 AB In Pompe disease, a lysosomal glycogen storage disorder, cardiac and skeletal muscle abnormalities are responsible for premature death and severe weakness. Swollen glycogen-filled lysosomes, the expected pathology, are accompanied in skeletal muscle by a secondary pathology massive accumulation of autophagic debris-that appears to contribute greatly to the weakness. We have tried to reproduce these defects in murine, Pompe myotubes derived from either primary myoblasts or myoblasts with extended proliferative capacity. The cells accumulated large lysosomes filled with glycogen, but, to our disappointment, did not have autophagic buildup even though basal autophagy was intact. When we suppressed autophagy by knocking down Atg7, we found that glycogen uptake by lysosomes was not affected, suggesting that macroautophagy is not the major pathway for glycogen delivery to lysosomes. But two apparently incidental observations-a peculiar distribution of both microinjected dextran and of small acidic structures adjacent to the interior membrane of large alkalinized glycogen-containing lysosomes-raised the possibility that glycogen traffics to the lysosomes by microautophagy or/and by the engulfment of small lysosomes by large ones. The cultured myotubes, therefore, appear to be a useful model for studying the mechanisms involved in glycogen accumulation in Pompe disease and to test substrate deprivation approaches.

In our previous study, it was demonstrated that IT and protective antigen (PA) induce autophagy in mammalian cells. Preliminary results suggest that autophagy may function as a cellular defense mechanism against LT-mediated toxemia. This degradation pathway may also be relevant to other aspects of the immune response in both innate and adaptive immunity. Understanding the role of autophagy in response to anthrax infection and the possibility of modulating this degradation pathway as potential countermeasures are subjects for further investigation.

Although the role of NO in regulating cardiac function has been investigated in depth, the physiological signalling effects of nitrite on cardiac function have only recently been explored. We now show that remarkably low concentrations of nitrite (1 nM) significantly modulate cardiac contractility in isolated and perfused Langendorff rat heart. In particular, nitrite exhibits potent negative inotropic and lusitropic activities as evidenced by a decrease in left ventricular pressure and relaxation, respectively. Furthermore, we demonstrate that the nitrite-dependent effects are mediated by NO formation but independent of NO synthase (NOS) activity. Specifically, nitrite infusion in the Langendorff system produces NO and cGMP/PKG-dependent negative inotropism, as evidenced by the formation of cellular iron-nitrosyl complexes and inhibition of biological effect by NO scavengers and by PKG inhibitors. These data are consistent with the hypothesis that nitrite represents an eNOS-independent source of NO in the heart which modulates cardiac contractility through the NO-cGMP/PKG pathway. The observed high potency of nitrite supports a physiological function of nitrite as a source of cardiomyocyte NO and a fundamental signalling molecule in the heart. (C) 2009 Elsevier B.V.

Recent advances in the understanding of the chemistry of HNO has led to the an understanding of HNO biochemistry which is vastly different from the known chemistry and biochemistry of nitric oxide (NO), the one-electron oxidation product of HNO. The cardiovascular roles of NO have been extensively studied, as NO is a key modulator of vascular tone and is involved in a number of vascular related pathologies. HNO displays unique cardiovascular properties and has been shown to have positive lusitropic and ionotropic effects in failing hearts without a chronotropic effect. Additionally, HNO causes a release of CGRP and modulates calcium channels such as ryanodine receptors. HNO has shown beneficial effects in ischemia reperfusion injury, as HNO treatment before ischemia-reperfusion reduces infarct size. In addition to the cardiovascular effects observed, HNO has shown initial promise in the realm of cancer therapy. HNO has been demonstrated to inhibit GAPDH, a key glycolytic enzyme. Due to the Warburg effect, inhibiting glycolysis is an attractive target for inhibiting tumor proliferation. Indeed, HNO has recently been shown to inhibit tumor proliferation in mouse xenografts. Additionally, HNO inhibits tumor angiogenesis and induces cancer cell apoptosis. The effects seen with HNO donors are quite different from NO donors and in some cases are opposite. The chemical nature of HNO explains how HNO and NO, although closely chemically related, act so differently in biochemical systems. This also gives insight into the potential molecular motifs that may be reactive towards HNO and opens up a novel field of pharmacological development. Published by Elsevier B.V.

Once the basal bio-production became evident its pathophysiological role started to be investigated in depth. H2S is a gas that can be formed by the action of two enzymes, cystathionine gamma-lyase and cystathionine beta-synthase, both involved in the metabolism of cysteine. It has several features in common with the other two well known "gasotransmitters" (nitric oxide and carbon monoxide) in the biological systems. These three gasses share some biological targets; however, they also have dissimilarities. For instance, the three gases target heme-proteins and open K-ATP channels: H2S as NO is an antioxidant, but in contrast to the latter molecule, H2S does not directly form radicals. In the last years H2S has been implicated in several physiological and pathophysiological processes such as long term synaptic potentiation, vasorelaxation, pro-and anti-inflammatory conditions, cardiac inotropism regulation, cardioprotection, and several other physiological mechanisms. We will focus on the biological role of H2S as a molecule able to trigger cell signaling. Our attention will be particularly devoted on the effects in cardiovascular system and in cardioprotection. We will also provide available information on H2S-donating drugs which have so far been tested in order to conjugate the beneficial effect of H2S with other pharmaceutical properties.

Here we report studies of a conserved arginine predicted to localize near the cytoplasmic side of TM1. First, we determined the effect of losing charge and bulk at this position via substitutions with glycine and alanine. The R383G mutant when transfected into HEK cells was not detectable on immunoblot or by functional assay, while the R383A mutant exhibited detectable but significantly decreased levels compared to wild-type, partial retention in the ER and altered glycosylation. Efflux of the ABCG2-substrates mitoxantrone and pheophorbide a was observed. Our experiments suggested rapid degradation of the R383A mutant by the proteasome via a kifunensine-insensitive pathway. Interestingly, overnight treatment of the R383A mutant with mitoxantrone assisted in protein maturation as evidenced by a shift to the N-glycosylated form. The R383A mutant when expressed in insect cells, though detected on the surface, had no measurable ATPase activity. In addition, substitution with the positively charged lysine resulted in significantly decreased protein expression levels in HEK cells, while retaining function. In conclusion, arginine 383 is a crucial residue for ABCG2 biogenesis. where even the most conservative mutations have a large impact. Published by Elsevier B.V.

It is also hoped that such an understanding will allow identification of individuals at risk for disease prior to the onset of motor symptoms. A large amount of work has already been performed in the identification of genetic risk factors for PD and some of this work, particularly those efforts that focus on genes implicated in monogenic forms of PD, have been successful, although hard won. A new era of gene discovery has begun, with the application of genome wide association studies; these promise to facilitate the identification of common genetic risk loci for complex genetic diseases. This is the first of several high throughput technologies that promise to shed light on the (likely) myriad genetic factors involved in this complex, late-onset neurodegenerative disorder.

Kobayashi, Hisataka TI In Vivo Stable Tumor-Specific Painting in Various Colors Using Dehalogenase-Based Protein-Tag Fluorescent Ligands SO BIOCONJUGATE CHEMISTRY LA English DT Article ID IMMUNOFLUORESCENCE; TECHNOLOGY; TISSUE AB In vivo fluorescence cancer imaging is an important tool in understanding tumor growth and therapeutic monitoring and can be performed either with endogenously produced fluorescent proteins or with exogenously introduced fluorescent probes bound to targeting molecules. However, endogenous fluorescence proteins cannot be altered after transfection, thus requiring rederivation of cell lines for each desired color, while exogenously targeted fluorescence probes are limited by the heterogeneous expression of naturally occurring cellular targets. In this study, we adapted the dehalogenase-based protein-Tag (HaloTag) system to in vivo cancer imaging, by introducing highly expressed HaloTag receptors (HaloTagR) in cancer cells coupled with a range of externally injected fluorophore-conjugated dehalogenase-reactive reactive linkers. Tumor nodules arising from a single transfected cell line were stably labeled with fluorescence varying in emission spectra front green to near-infrared. After establishing and validating a SHIN3 cell line stably transfected with HaloTagR (HaloTagR-SHIN3), in vivo spectral fluorescence imaging Studies were performed in live animals using a peritoneal dissemination model. The tumor nodules arising from HaloTagR-SHIN3 could be successfully labeled by four different fluorophore-conjugated HaloTag-ligands each emitting light at different wavelengths. These fluorophores could be alternated on serial imaging sessions permitting assessment of interval growth. Fluorescence was retained in histological specimens after fixation. Thus, this tagging system proves versatile both for in vivo and in vitro imaging without requiring modification of the underlying cell line. Thus, this strategy can overcome some of the limitations associated with the use of endogenous fluorescent proteins and exogenous targeted optical agents in current use.

The C-terminal extended fusion polypeptides of these recombinant scFv fusion proteins are used as the acceptor substrate for human polypeptide-alpha-N-acetylgalactosaminyltransferase II (h-ppGalNAc-T2) that transfers either GalNAc or 2-keto-Gal. a modified galactose with a chemical handle. from their respective UDP-sugars to the side-chain hydroxyl group of the Thr residue(s). The recombinant scFv fusion proteins are expressed in E. coli as inclusion bodies and in vitro refolded and glycosylated with h-ppGaINAc-T2. Upon protease cleavage. the MALDI-TOF spectra of the glycosylated C-terminal fusion polypeptides showed that the glycosylated scFv fusion protein with a single Thr residue is fully glycosylated with a single 2-keto-Gal, whereas the glycosylated scFv fusion protein with 3 and 17 Thr residues is found as all equal mixture of 2-3 and 5-8 2-keto-Gal glycosylated fusion proteins, respectively. These fusion scFv proteins with the modified galactose are then conjugated with a fluorescence probe, Alexa488, that carries an orthogonal reactive group. The fluorescence labeled scFv proteins bind specifically to a human breast. cancer cell line (SK-BR-3) that overexpresses the HER2 receptor, indicating that the in vitro folded scFv fusion proteins are biologically active and the presence of conjugated multiple Alexa488 probes in their C-terminal end does not interfere with their binding to the antigen.

The method involves preforming the metal-ligand chelate in alcohol prior to conjugation to the dendrimer. The dendrimer-based agent was purified by a Sephadex G-25 column and characterized by elemental analysis. The analysis and SE-HPLC data gave a chelate to dendrimer ratio of 30:1 Suggesting conjugation at approximately every other amine terminal on the dendrimer. Molar relaxivity of the agent measured at pH 7.4 displayed a higher value than that of the analogous G4 dendrimer based agent prepared by the postmetal incorporation method (r(1) = 26.9 vs 13.9 mM(-1) s(-1) at 3 T and 22 degrees C). This is hypothesized to be due to the higher hydrophobicity of this conjugate and the lack of available charged carboxylate groups from noncomplexed free ligands that might coordinate to the metal and thus also reduce water exchange sites. Additionally, the distribution populations of compounds that result from the postmetal incorporation route are eliminated from the current product simplifying characterization as quality control issues pertaining to the production Of Such agents for clinical use as MR contrast agents. In vivo imaging in mice showed a reasonably fast clearance (t(1/2) = 24 min) suggesting a viable agent for use in clinical application.

A common single nucleotide polymorphism (C385A) in the human FAAH gene has been associated with increased risk for addiction and obesity. Methods: Using imaging genetics in 82 healthy adult volunteers, we examined the effects of FAAH C385A on threat- and reward-related human brain function. Results: Carriers of FAAH 385A, associated with reduced enzyme and possibly increased eCB signaling, had decreased threat-related amygdala reactivity but increased reward-related ventral striatal reactivity in comparison with C385 homozygotes. Similarly divergent effects of FAAH C385A genotype were manifest at the level of brain-behavior relationships. The 385A carriers showed decreased correlation between amygdala reactivity and trait anxiety but increased correlation between ventral striatal reactivity and delay discounting, an index of impulsivity. Conclusions: Our results parallel pharmacologic and genetic dissection of eCB signaling, are consistent with the psychotropic effects of Delta(9)-tetrahydrocannabinol, and highlight specific neural mechanisms through which variability in eCB signaling impacts complex behavioral processes related to risk for addiction and obesity.

However, little is known about the differential sensitivity of PTSD individuals to unpredictable stressors, relative to either healthy individuals or individuals with other anxiety disorders. This study tested the hypothesis that elevated anxious reactivity, specifically for unpredictable aversive events, is a psychophysiological correlate of PTSD. Methods: Sixteen patients with PTSD (34.5 +/- 12.4 years) were compared with 18 patients with generalized anxiety disorder (GAD) (34.0 +/- 10.5 years) and 34 healthy control subjects (30.2 +/- 8.5 years). Participants were exposed to three conditions: one in which predictable aversive stimuli were signaled by a cue, a second in which aversive stimuli were administered unpredictably, and a third in which no aversive stimuli were anticipated. Startle magnitude was used to assess anxious responses to the threat cue and to contexts associated with each condition. Results: Posttraumatic stress disorder and GAD patients showed normative enhancement of fear to the predictable threat cue, but the PTSD group displayed elevated anxiety during the unpredictable condition compared with participants with GAD and healthy control subjects. Conclusions: Anxious reactivity to unpredictable aversive events was heightened in PTSD but not in GAD and healthy subjects. Prior works also found signs of increased reactivity to unpredictable threat in panic disorder (PD), suggesting that PTSD and PD may involve shared vulnerability. As such, the current results inform understandings of classification, pathophysiology, and psychopharmacology of anxiety disorders, generally, and PTSD and panic disorder specifically.

TI Decreased Neurokinin-1 (Substance P) Receptor Binding in Patients with Panic Disorder: Positron Emission Tomographic Study with [F-18]SPA-RQ SO BIOLOGICAL PSYCHIATRY LA English DT Article DE NK1; receptor; panic attack; panic disorder; positron emission tomography (PET); substance P ID HUMAN BRAIN; NK1 RECEPTORS; ANTAGONIST; STRESS; PET; ANXIETY; PHOBIA AB Background: Positron emission tomography (PET) can localize and quantify neurokinin-1 (NK1) receptors in brain using the nonpeptide antagonist radioligand, [F-18]SPA-RQ. We sought to determine if patients with panic disorder have altered density of INK, receptors in brain because of their history of recurrent panic attacks. We also sought to determine if a drug-induced panic attack releases substance P in brain, as measured by decreased binding of [F-18]SPA-RQ. Methods: Positron emission tomography scans with [F-18]SPA-RQ were performed in 14 patients with panic disorder and 14 healthy subjects. Of these two groups, 7 patients and 10 healthy subjects were scanned twice, once at baseline and once after injection of doxapram, a drug that induces panic attacks. Results: NK1 receptor binding in patients (n = 14) compared with that in healthy subjects (n = 14) was significantly decreased by 12% to 21% in all brain regions. Doxapram effectively produced panic attacks in 6 of 7 patients with panic disorder but only 2 of 10 healthy subjects. Doxapram caused no significant change of [F-18]SPA-RQ binding in either patients or healthy subjects. Conclusions: Although induction of a panic attack has no significant effect on [F-18]SPA-RQ binding to NK1 receptors, patients with panic disorder have widespread reduction of NK1 receptor binding in brain.

TI Genome-Wide Screen Identifies Drug-Induced Regulation of the Gene Giant Axonal Neuropathy (Gan) in a Mouse Model of Antiretroviral-Induced Painful Peripheral Neuropathy SO BIOLOGICAL RESEARCH FOR NURSING LA English DT Article DE microarray; painful peripheral neuropathy; chronic pain; gigaxonin; giant axonal neuropathy; HIV/AIDS; HAART; NRTI ID SENSORY NEUROPATHY; CLINICAL-FEATURES; TOXIC NEUROPATHY; RISK-FACTORS; THERAPY; EPIDEMIOLOGY; DENSITY; AIDS AB Painful peripheral neuropathy is a debilitating complication of the treatment of HIV with nucleoside reverse transcriptase inhibitors (NRTIs). Patients are living longer with these drugs; however many develop excruciating, unremitting, and often treatment-limiting neuropathy that is resistant to conventional pain management therapies. Improving patient comfort and quality of life is paramount and depends on a clearer understanding of this devastating side effect. The mechanisms underlying the development of NRTI-induced neuropathy, however, remain unclear. Using a mouse model of NRTI-induced neuropathy, the authors conducted an unbiased whole-genome microarray screen to identify molecular targets in the spinal dorsal horn, which is the location where integration of ascending sensory transmission and descending modulatory effects Occur. Analysis of the microarray data identified a change in the gene giant axonal neuropathy 1 (Gan1). Mutation of this gene has been linked to the development of giant axonal neuropathy (GAN), a rare autosomal recessive condition characterized by a progressive sensorimotor neuropathy. Gan1 has not been previously linked to nerve pathologies in other populations. In this study, downregulation of the Gan1 gene and the gene protein product, gigaxonin, was validated via quantitative polymerase chain reaction ([qPCR] gene expression) and Western blot analyses (protein level). Our report is the first to suggest that Gan1 might be a novel molecular target in the development of NRTI-induced peripheral neuropathy with implications for new therapeutic approaches to preventing or reducing a significant side effect of HIV treatment.

Using the Center for International Blood and Marrow Transplant Research database, we retrospectively evaluated 23 HIV-positive patients undergoing matched sibling donor (n = 19) or unrelated donor (n = 4) alloHCT between 1987 and 2003. The median age at alloHCT was 32 years. Indications for alloHCT were diverse and included malignant (n = 21) and nonmalignant (n = 2) hematologic disorders. Nine patients (39%) underwent transplantation after 1996, the approximate year that highly active antiretroviral therapy became standard treatment. The median time to neutrophil engraftment was 16 days (range, 7 to 30 days), and the cumulative incidences of grade II-IV acute graft-versus-host disease (aGVHD) at 100 days, chronic GVHD (cGVHD), and survival at 2 years were 30% (95% confidence interval [CI] = 14% to 50%), 28% (95% CI = 12% to 48%), and 30% (95% CI = 14% to 50%), respectively. At a median follow-up of 59 months, 6 patients were alive. Survival appears to be better in the patients undergoing alloHCT after 1996; 4 of these 9 patients survived, compared with only 2 of 14 those undergoing transplantation before 1996. These data suggest that alloHCT is feasible for selected HIV-positive patients with malignant and nonmalignant disorders. Prospective studies are needed to evaluate the safety and efficacy of this modality in specific diseases in these patients.

And tumor necrosis factor-alpha (TNF-alpha) is a positive regulator of VEGF. This study was aimed to identify the signalling pathway of TNF-alpha in VEGF expression regulation in breast cancer cell line MCF7. Using luciferase reporter assays, we demonstrated that TNF-alpha significantly increased activator protein-1 (AP-1) transcriptional activity in the MCF7 cells. The expression of the AP-1 family members c-Jun, c-Fos and JunB and phosphorylation levels of c-Jun were upregulated by TNF-alpha, whereas other AP-1 family members Fra-1, Fra-2, and JunD were unaffected. The activation of AP-1 was associated with the formation of p-c-Jun-c-Jun and p-c-Jun-JunB homodimers. Furthermore, the phosphorylation levels of c-Jun N-terminal kinase (JNK) but not P38 and ERK were elevated by TNF-alpha in MCF7 cells. TNF-alpha potently upregulated the mRNA and protein levels of VEGF, which were significantly reversed by JNK inhibitor SP600125. Finally using chromatin immunoprecipitation (CHIP) assays, we found that p-c-Jun bound to the VEGF promoter and regulated VEGF transcription directly. These data suggest that the pro-inflammatory cytokine TNF-alpha is a critical regulator of VEGF expression in breast cancer cells, at least partially via a JNK and AP-1 dependent pathway.

The development of SAR included strategic incorporation of known substituents on the critical catachol diether moiety of the 6-phenyl appendage on each heterocyclic core. From these studies, (R)-3-(2,5-dimethoxyphenyl)-6-(4-methoxy-3-(tetrahydrofuran-3-yloxy)phenyl)-7H-[1,2,4]triazolo[3,4-b][1,3,4]thiadiazine (10) and (R)-3-(2,5-dimethoxyphenyl)-6-(4-methoxy-3-(tetrahydrofuran-3-yloxy)phenyl)-[1,2,4]triazolo[4,3-b]pyridazine (18) were identified as highly potent PDE4A inhibitors. Each of these analogues was submitted across a panel of 21 PDE family members and was shown to be highly selective for PDE4 isoforms (PDE4A, PDE4B, PDE4C, PDE4D). Both 10 and 18 were then evaluated in divergent cell-based assays to assess their relevant use as probes of PDE4 activity. Finally, docking studies with selective ligands (including 10 and 18) were undertaken to better understand this chemotypes ability to bind and inhibit PDE4 selectively.

The objective of the present study was to identify hypercoagulable states associated with development of venous thromboembolism in thalidomide-treated multiple myeloma patients. We screened 49 consecutive multiple myeloma patients treated with thalidomide at baseline for hypercoagulability. With a median follow-up of 11 months, 10 of 49 multiple myeloma patients developed a thrombotic episode. Laboratory assays revealed an underlying abnormality in nine of the 10 patients; hypercoagulable screenings were normal in 36 of the 39 patients who did not develop venous thromboembolism (P<0.0001). Our retrospective study results suggest that the multiple myeloma patients with thromboembolic complications during treatment with thalidomide have a frequent concomitant underlying thrombophilic state.

TI Glucocerebrosidase mutations in clinical and pathologically proven Parkinson's disease SO BRAIN LA English DT Article DE Parkinson's disease; GBA; Gaucher's disease; neuropathology ID LEWY BODY DISORDERS; GAUCHER-DISEASE; GENE-MUTATIONS; ASHKENAZI-JEWS; VISUAL HALLUCINATIONS; RISK-FACTOR; DIAGNOSIS; ONSET; ASSOCIATION; FREQUENCIES AB Mutations in the glucocerebrosidase gene (GBA) are associated with Gaucher's disease, the most common lysosomal storage disorder. Parkinsonism is an established feature of Gaucher's disease and an increased frequency of mutations in GBA has been reported in several different ethnic series with sporadic Parkinson's disease. In this study, we evaluated the frequency of GBA mutations in British patients affected by Parkinson's disease. We utilized the DNA of 790 patients and 257 controls, matched for age and ethnicity, to screen for mutations within the GBA gene. Clinical data on all identified GBA mutation carriers was reviewed and analysed. Additionally, in all cases where brain material was available, a neuropathological evaluation was performed and compared to sporadic Parkinson's disease without GBA mutations. The frequency of GBA mutations among the British patients (33/790 = 4.18%) was significantly higher (P = 0.01; odds ratio = 3.7; 95% confidence interval = 1.12-12.14) when compared to the control group (3/257 = 1.17%). Fourteen different GBA mutations were identified, including three previously undescribed mutations, K7E, D443N and G193E. Pathological examination revealed widespread and abundant alpha-synuclein pathology in all 17 GBA mutation carriers, which were graded as Braak stage of 5-6, and had McKeith's limbic or diffuse neocortical Lewy body-type pathology. Diffuse neocortical Lewy body-type pathology tended to occur more frequently in the group with GBA mutations compared to matched Parkinson's disease controls. Clinical features comprised an early onset of the disease, the presence of hallucinations in 45% (14/31) and symptoms of cognitive decline or dementia in 48% (15/31) of patients. This study demonstrates that GBA mutations are found in British subjects at a higher frequency than any other known Parkinson's disease gene. This is the largest study to date on a non-Jewish patient sample with a detailed genotype/phenotype/pathological analyses which strengthens the hypothesis that GBA mutations represent a significant risk factor for the development of Parkinson's disease and suggest that to date, this is the most common genetic factor identified for the disease.

TI Gene expression profiling of substantia nigra dopamine neurons: further insights into Parkinson's disease pathology SO BRAIN LA English DT Article DE Parkinson's disease; microarray; laser microdissection; pathogenesis; dopamine ID CELL-DEATH; UBIQUITIN-PROTEASOME; OXIDATIVE STRESS; ALPHA-SYNUCLEIN; PROTEIN; RECEPTORS; BRAIN; INVOLVEMENT; MECHANISMS; PATHWAYS AB Parkinson's disease is caused by a progressive loss of the midbrain dopamine (DA) neurons in the substantia nigra pars compacta. Although the main cause of Parkinson's disease remains unknown, there is increasing evidence that it is a complex disorder caused by a combination of genetic and environmental factors, which affect key signalling pathways in substantia nigra DA neurons. Insights into pathogenesis of Parkinson's disease stem from in vitro and in vivo models and from postmortem analyses. Recent technological developments have added a new dimension to this research by determining gene expression profiles using high throughput microarray assays. However, many of the studies reported to date were based on whole midbrain dissections, which included cells other than DA neurons. Here, we have used laser microdissection to isolate single DA neurons from the substantia nigra pars compacta of controls and subjects with idiopathic Parkinson's disease matched for age and postmortem interval followed by microarrays to analyse gene expression profiling. Our data confirm a dysregulation of several functional groups of genes involved in the Parkinson's disease pathogenesis. In particular, we found prominent down-regulation of members of the PARK gene family and dysregulation of multiple genes associated with programmed cell death and survival. In addition, genes for neurotransmitter and ion channel receptors were also deregulated, supporting the view that alterations in electrical activity might influence DA neuron function. Our data provide a 'molecular fingerprint identity' of late-stage Parkinson's disease DA neurons that will advance our understanding of the molecular pathology of this disease.

This resource is available to researchers worldwide for collaborative studies. Herein, we report the results of testing for germline mutations in BRCA1 and BRCA2. We have tested 4,531 probands for mutations in BRCA1 and 4,084 in BRCA2. Deleterious mutations in BRCA1 and BRCA2 were identified for 9.8% of probands tested [233/4,531 (5.1%) for BRCA1 and 193/4,084 (4.7%) for BRCA2]. Of 1,385 Ashkenazi Jewish women tested for only the three founder mutations, 17.4% carried a deleterious mutation. In total, from the proband and subsequent family testing, 1,360 female mutation carriers (788 in BRCA1, 566 in BRCA2, 6 in both BRCA1 and BRCA2) have been identified. The value of the resource has been greatly enhanced by determining the germline BRCA1 and BRCA2 mutation statuses of nearly 6,000 probands.

METHODS: We prospectively examined the association of height with prostate cancer among 34268 men in the prostate, lung, colorectal, and ovarian cancer trial. Anthropometry was assessed at baseline and 2144 incident prostate cancer cases were identified upto 8.9 years of follow-up. RESULTS: Overall, tallness was not associated with the risk of prostate cancer or with the risk of non-aggressive disease, but the risk for aggressive prostate cancer tended to be greater in taller men (Gleason score >> 7 or stage XIII; P trend 0.05; relative risk (RR) for 190 cm + vs << 170 cm = 1.39, 95% confidence interval (95% CI): 0.96-2.01). This association was largely limited to men below the age of 65 years (P trend = 0.008; RR for 190 cm + vs << 170 cm = 1.76, 95% CI: 1.06-2.93; P for interaction = 0.009), although the number of cases was small and risk estimates were somewhat unstable. CONCLUSION: The results of this large prospective prostate cancer screening trial suggest that tallness is associated with increased risk for younger onset aggressive prostate cancer.

SO BRITISH JOURNAL OF DERMATOLOGY LA English DT Article DE contact allergy; cytokine; enzyme-linked immunospot assay; patch test ID ALLERGIC CONTACT-DERMATITIS; IN-VITRO; TRUE TEST(TM); REPRODUCIBILITY; TH1-TYPE; TH2-TYPE; ELICITS AB Background Patch test reactivity to nickel varies over time. To what extent this variation is associated with fluctuations in the T-cell reactivity to nickel is not known. Objectives Our aim was to investigate the relationship between variation over time in the patch test and the systemic T-cell reactivity to nickel. Methods Patients (n = 15) with a history of contact allergy to nickel were subjected to three consecutive patch tests at 3-month intervals, utilizing NiSO(4) at 10 concentrations ranging from 0.0032% to 12.5%. Prior to each patch test, blood mononuclear cells were analysed for T-cell reactivity to nickel by interleukin (IL)-4 and IL-13 enzyme-linked immunospot assay. Results Eleven patients reacted positively in all three patch tests, two patients reacted in one or two tests and two remained negative. All 13 positive patients displayed variability over time, in terms of the lowest dose of nickel to which they responded. Also the cytokine response to nickel varied over time but the patients' mean cytokine response was positively correlated with their mean patch test reactivity (r(s) = 0.70, P < 0.01 for IL-4; r(s) = 0.78, P < 0.001 for IL-13). However, although the changes over time in patch test reactivity and the cytokine responses to nickel displayed a similar pattern in many patients, there was no significant correlation between the individuals' variation over time in vivo and in vitro. Conclusions The overall magnitude of the T-cell reactivity to nickel and the patch test reactivity are closely associated but fluctuations in the systemic T-cell reactivity cannot be singled out as the major cause of longitudinal variability in nickel patch test reactivity.

Using large population registries from Sweden, we evaluated risk of lymphoma subtypes among first-degree relatives of 2668 follicular lymphoma (FL) patients, 2517 diffuse large B-cell lymphoma (DLBCL) patients, and 6963 Hodgkin lymphoma (HL) patients compared to first-degree relatives of controls. Relatives were at the highest risk for developing the same lymphoma subtype as the case. DLBCL was increased 10-fold among relatives of DLBCL patients, FL was increased fourfold among relatives of FL patients and HL was increased fourfold among relatives of HL patients. These results imply that germline susceptibility genes are specific to lymphoma subtype.

However, for virtually all patients with metastatic or recurrent disease, survival remains dismal. The important role that members of the insulin-like growth factor (IGF) family play in tumorigenesis has been known for decades. But it has only been in the last five years, that humanized and fully human antibodies targeting insulin-like growth factor receptor 1 (IGF-1R) have been developed. The use of these agents in clinical trials has been accompanied by several dramatic responses in patients with recurrent and refractory sarcomas. In this review, we will focus on preclinical highlights in the past, current clinic trials and discuss some exciting research opportunities to foster advances in the future.

To date, no study has compared the trends in thyroid cancer incidence across continents. We examined incidence data from cancer incidence in five continents (CI5) over the 30-year period 1973-2002 from 19 populations in the Americas, Asia, Europe, and Oceania. Thyroid cancer rates have increased from 1973-1977 to 1998-2002 for most of the populations except Sweden, in which the incidence rates decreased about 18% for both males and females. The average increase was 48.0% among males and 66.7% among females. More recently, the age-adjusted international thyroid cancer incidence rates from 1998 to 2002 varied 5-fold for males and nearly 10-fold for females by geographic region. Considerable variation in thyroid cancer incidence was present for every continent but Africa, in which the incidence rates were generally low. Our analysis of published CI5 data suggests that thyroid cancer rates increased between 1973 and 2002 in most populations worldwide, and that the increase does not appear to be restricted to a particular region of the world or by the underlying rates of thyroid cancer.

Potentially modifiable factors related to fasting insulin and glucose concentrations may influence pancreatic cancer risk. Multiple linear regression models were used to identify anthropometric, clinical, behavioral, and dietary factors associated with fasting insulin and glucose in a subcohort of non-diabetics in the Alpha-Tocopherol, Beta-Carotene Cancer Prevention Study (n = 366). Hazards ratios (HRs) and 95% confidence intervals (CIs) were calculated among the larger cohort (n = 27,035). During follow-up (median 16.1 years), 305 participants developed pancreatic cancer. Fasting insulin and/or glucose were positively associated with body mass index (BMI), height, and dietary total and saturated fat and inversely associated with serum high-density lipoprotein cholesterol (HDL) and dietary available carbohydrates, sucrose, and alcohol. Comparing highest to lowest quintiles, total fat (HR = 1.54, 95% CI 1.05-2.25, p-trend = 0.01) and saturated fat (HR = 1.38, 95% CI 0.97-1.98, p-trend = 0.06) were positively associated and available carbohydrates (HR = 0.63, 95% CI 0.44-0.90, p-trend = 0.01), particularly sucrose (HR = 0.62, 95% CI 0.43-0.89, p-trend = 0.09), were inversely associated with risk of pancreatic cancer. BMI, HDL, height, and alcohol were not associated with pancreatic cancer risk. Dietary fat is associated with higher fasting insulin concentrations and may increase pancreatic cancer risk in smokers.

TI Prospective study of physical activity and the risk of ovarian cancer SO CANCER CAUSES & CONTROL LA English DT Article DE Physical activity; Cancer; Prospective study ID LARGE COHORT; FOLLOW-UP; WOMEN; LIFE; HEALTH; BREAST AB Available studies on physical activity and ovarian cancer have produced inconsistent findings, with some previous studies reporting a positive association between vigorous physical activity and ovarian cancer risk. We prospectively investigated the relations of self-reported moderate and vigorous physical activity to ovarian cancer in a cohort of 96,216 US women aged 51-72 years at baseline, followed from 1996-1997 to 31 December 2003. During seven years of follow-up, we documented 309 cases of epithelial ovarian carcinoma. In analyses adjusted for age, the relative risks (RRs) of ovarian cancer for individual and joint combinations of moderate and vigorous physical activity such as entirely inactive, neither moderate nor vigorous physical activity, moderate physical activity only, vigorous physical activity only, and both moderate and vigorous physical activity were 0.88, 1.0 (reference), 0.89, 1.05, and 1.08 (95% confidence interval (CI) = 0.81-1.43, respectively. After multivariate adjustment, the relation was essentially unchanged (RR comparing women with both moderate and vigorous physical activity to those with neither moderate nor vigorous physical activity = 1.10; 95% CI = 0.82-1.48). The null association between physical activity and ovarian cancer persisted in subgroups of women as defined by body mass index, parity, oral contraceptive use, menopausal hormone therapy, family history of ovarian cancer, and other variables (all p values for interaction > 0.05). Neither moderate nor vigorous physical activity showed a statistically significant association with ovarian cancer in this large cohort of women.

Included in this analysis were 478,400 subjects, of whom detailed information on the intake of alcoholic beverages at baseline and over lifetime was collected between 1992 and 2000. During a median follow-up time of 8.9 years, 555 non-endocrine pancreatic cancer cases were observed. Multivariate Cox proportional hazard models were used to examine the association of ethanol intake at recruitment and average lifetime ethanol intake and pancreatic cancer adjusting for smoking, height, weight, and history of diabetes. Overall, neither ethanol intake at recruitment (relative risk (RR) = 0.94, 95% confidence interval (CI) 0.69-1.27 comparing 30+ g/d vs. 0.1-4.9 g/d) nor average lifetime ethanol intake (RR = 0.95, 95% CI 0.65-1.39) was associated with pancreatic cancer risk. High lifetime ethanol intake from spirits/liquor at recruitment tended to be associated with a higher risk (RR = 1.40, 95% CI 0.93-2.10 comparing 10+ g/d vs. 0.1-4.9 g/d), but no associations were observed for wine and beer consumption. These results suggest no association of alcohol consumption with the risk of pancreatic cancer.

Interaction with ABCG2 was determined by ATPase assay, competition of [(125)I]iodoarylazidoprazosin (IAAP) photolabeling and flow cytometry. Cellular resistance was measured in 4-day cytotoxicity assays. ABCG2 expression was measured by fluorescent-substrate transport assays and immunoblot. Becatecarin competed [(125)I]-IAAP labeling of ABCG2, stimulated ATPase activity and, at concentrations greater than 10 mu M, inhibited ABCG2-mediated transport. Becatecarin-selected A549 Bec150 lung carcinoma cells were 3.1-, 15-, 8-, and 6.8-fold resistant to becatecarin, mitoxantrone, SN-38 and topotecan, respectively. A549 Bec150 cells transported the ABCG2 substrates pheophorbide a, mitoxantrone and BODIPY-prazosin and displayed increased staining with the anti-ABCG2 antibody 5D3 compared to parental cells. Increased ABCG2 expression was confirmed by immunoblot. Our results suggest that becatecarin is transported by ABCG2 and can induce ABCG2 expression in cancer cells.

Methods: A population-based case-control study was conducted including 194 cases identified through the Metropolitan Detroit Cancer Surveillance System and 189 controls recruited through random digit dialing to examine polymorphisms in genes involved in estrogen metabolism and action. Results: The African American-specific CYP1A1 5639C allele was associated with an increased risk of breast cancer (odds ratio (OR) = 2.34, 95% confidence interval (CI) 1.23-4.44) and this association with the CYP1A1 5639 locus was dependent on another polymorphism in the CYP3A4 gene (P = 0.043 for the interaction). In addition, African American-predominant CYP1B1 432 Val allele was significantly more often found in the cases than in the controls overall and the HSD17B1 312 Gly allele was specifically associated with premenopausal breast cancer risk (OR = 3.00, 95%CI 1.29-6.99). Conclusion: These observations need to be confirmed in larger studies due to the limited statistical power of the study based on a small number of cases.

TI A mini-review of familial ovarian germ cell tumors: An additional manifestation of the familial testicular germ cell tumor syndrome SO CANCER EPIDEMIOLOGY LA English DT Review DE Ovarian germ cell tumor; Familial; Epidemiology; Testicular germ cell tumor; Genetic predisposition; SEER ID 2 SIBLINGS; CANCER; RISK; DYSGERMINOMA; DYSGENESIS; EXPRESSION; GENETICS; BROTHER; BIOLOGY; GONADS AB Introduction While testicular germ cell tumors (TGCTs) are the most common malignancy in young men, germ cell tumors in women are uncommon. Familial clustering, epidemiologic evidence of increased risk with family or personal history of TGCT, and associations with genitourinary tract anomalies suggest an underlying genetic predisposition to TGCT, but traditional linkage studies have yet to identify a highly penetrant TGCT cancer susceptibility gene. In this paper, we investigate the familial occurrence of testicular and ovarian germ cell tumors. Methods We report a family in which a TGCT and an ovarian germ cell tumor (OGCT) occurred in two siblings, summarize the existing literature on familial occurrences of OGCT, either alone or in combination with extragonadal or TGCTs, and compare the incidence of familial and sporadic testicular and ovarian GCTs. Sporadic GCT data were obtained from the US Surveillance Epidemiology and End Results (SEER) registry. Results We identified 16 reports of OGCT occurring in conjunction with either ovarian, testicular or extragonadal GCT. In these familial cases, the mean age at onset of female dysgerminoma was younger than that noted in the general population (age 17 vs. age 24, p = 0.01). In SEER, the incidence of TGCT was 15 times higher than that of OGCT. Histologic distributions in males and females showed distinctly different patterns. Discussion Although the incidence of OGCTs in the general population is quite low, its occurrence in multiple members of the same family and in families with TGCT suggests that a gene conferring susceptibility to GCTs may exist in some families.

Methods: We calculated age-adjusted (2000 U.S. standard) rates for 1978 to 2005, and for five time periods from 1978-1983 through 2001-2005 according to histologic type and anatomic site, separately and jointly. We also analyzed rates by race, gender, and age group. Results: During 1978 to 2005, more than 54,000 stomach carcinoma cases were diagnosed among residents of the nine Surveillance, Epidemiology, and End Results areas. Total stomach carcinoma rates declined by 34% from the 1978-1983 to the 2001-2005 time periods. By histologic type, intestinal rates decreased consistently, whereas those for diffuse rates increased through 2000 and declined in recent years. By anatomic site, cardia rates increased during earlier years and then decreased, whereas rates for all other sites declined. When considered jointly by histologic type and anatomic site, intestinal carcinoma rates decreased for all sites except the cardia; diffuse rates increased through 2000 and decreased in recent years for all sites except the overlapping/nonspecified sites. Both diffuse and intestinal rates were lowest among whites, intermediate among blacks, and highest among the other, primarily Asian, races, with only modest gender differences for the diffuse type. In contrast, cardia carcinoma rates were highest among whites and were notably higher among males, especially whites among whom the male/female rate ratio was five to one. Conclusions: Stomach carcinoma incidence patterns differ by histologic type, anatomic site, race, gender, and age, suggesting that etiologic heterogeneity should be pursued in future research.

TI Responses to Online GSTM1 Genetic Test Results among Smokers Related to Patients with Lung Cancer: A Pilot Study SO CANCER EPIDEMIOLOGY BIOMARKERS & PREVENTION LA English DT Article ID SMOKING-CESSATION TREATMENT; AFRICAN-AMERICAN SMOKERS; NICOTINE DEPENDENCE; RISK; SUSCEPTIBILITY; IMPACT; FEEDBACK; MOTIVATION; PROGRAM; ANALOG AB Providing smokers with personal genetic test results indicating increased lung cancer risk may increase uptake of effective smoking cessation services. Using the internet may increase reach and enable real-time assessment of how people process genetic risk information away from the clinic setting. We therefore explored smokers' responses to Web-delivered GSTM1 genetic test results indicating higher or lower lung cancer risk. Participants were smokers (n = 44) biologically related to patients with newly diagnosed lung cancer. Measures were assessed at baseline, before and immediately after receipt of online genetic test results, and at 6-month follow-up. Outcomes included accurate comprehension of results, regret about being tested, cessation-related cognitions (e.g., perceived response efficacy), and uptake of free smoking cessation services (nicotine replacement therapy, printed self-help materials, telephone counseling sessions). Twenty-two "relative smokers" received a GSTM1-missing (higher risk) and 22 a GSTM1-present (lower risk) result. All relative smokers with GSTM1-missing results and 55% of those with GSTM1-present results accurately interpreted their results. No relative smokers regretted having taken the test. Relative smokers receiving GSTM1-missing results reported lower confidence that quitting could reduce lung cancer risk (perceived response efficacy) than those receiving GSTM1-present results. There were no other significant between-group differences. Uptake of smoking cessation services was high (e.g., 91% nicotine replacement therapy uptake). Genetic test results may not influence uptake of free smoking cessation services because of ceiling effects. Further research is needed to determine the risks and benefits of Web-based disclosure of genetic test results.

However, this relationship has only been assessed in a single relatively small study that was unable to assess the effect of migraine triggers, which are also well-established breast cancer risk factors (e.g., use of alcohol and exogenous hormones), on the inverse association observed. Utilizing data on 4,568 breast cancer cases and 4,678 controls who participated in a multicenter population-based case-control study in the United States, we evaluated the association between migraine history and breast cancer risk using unconditional logistic regression. Migraine history data were obtained from structured in-person interviews. Women with a history of migraine had a reduced risk of breast cancer [odds ratio, 0.74; 95% confidence interval (CI), 0.66-0.82]. This risk did not differ by menopausal status, age at migraine diagnosis, use of prescription migraine medications, or when analyses were restricted to women who avoided various migraine triggers (including alcohol, exogenous hormones, and smoking). These data support a previous finding that a history of migraine may be associated with a reduced risk of breast cancer. It extends the prior report in observing that this relationship holds for both premenopausal and postmenopausal women and is independent of exposure to common migraine triggers.

This qualitative study explored factors involved in the formulation of perceived breast cancer risk and associations between risk perception and lifestyle behaviors in white and black women with a family history of breast cancer. Eligible participants were North Carolina residents in the Sister Study, a nationwide study of risk factors for breast cancer among women who have at least 1 sister diagnosed with breast cancer. Personal interviews were conducted with 32 women. Although most had heightened perceived risk, almost 20% considered themselves below-to-average risk. Participants with moderate-to-high perceived risk were more likely to report an affected sister and mother, a first-degree relative's diagnosis within 4 years, and death of a first-degree relative from breast cancer. Many women were unaware of associations between lifestyle behaviors and breast cancer risk. Only one-third of the women reported healthy lifestyle changes because of family history; dietary change was most frequently reported. Findings may be important for cancer nurses involved in developing breast cancer education programs for women with a family history of breast cancer.

Previous studies have shown significant chemopreventive efficacy of ATB against human esophageal and lung cancers. We have recently developed a new mouse model for lung squamous cell carcinomas (SCC). In this study, lung SCC mouse model was characterized using small-animal imaging techniques (magnetic resonance imaging and computed tomography). ATB decreased lung SCC significantly (3.1-fold; P<0.05) and increased lung hyperplastic lesions by 2.4-fold (P<0.05). This observation suggests that ATB can block hyperplasia from progression to SCC. ATB tissue distribution was determined using matrine as a marker chemical. We found that ATB is rapidly absorbed and then distributes to various tissues including the lung. These results indicate that ATB is a potent chemopreventive agent against the development of mouse lung SCCs.

TI Functional Phosphodiesterase 11A Mutations May Modify the Risk of Familial and Bilateral Testicular Germ Cell Tumors SO CANCER RESEARCH LA English DT Article ID CANCER; GENE; PDE11A; HYPERPLASIA; PROTEIN; MEN AB Inactivating germline mutations in phosphodiesterase 11A (PDE11A) have been implicated in adrenal tumor susceptibility. PDE11A is highly expressed in endocrine steroidogenic tissues, especially the testis, and mice with inactivated Pde11a exhibit male infertility, a known testicular germ cell tumor (TGCT) risk factor. We sequenced the PDE11A gene-coding region in 95 patients with TGCT from 64 unrelated kindreds. We identified 8 nonsynonymous substitutions in 20 patients from 15 families: four (R52T, F258Y, G291R, and V820M) were newly recognized, three (R804H, R867G, and M878V) were functional variants previously implicated in adrenal tumor predisposition, and one (Y727C) was a known polymorphism. We compared the frequency of these variants in our patients to unrelated controls that had been screened and found negative for any endocrine diseases: only the two previously reported variants, R804H and R867G, known to be frequent in general population, were detected in these controls. The frequency of all PDE11A-gene variants (combined) was significantly higher among patients with TGCT (P = 0.0002), present in 19% of the families of our cohort. Most variants,were detected in the general population, but functional studies showed that all these mutations reduced PDE activity, and that PDE11A protein expression was decreased (or absent) in TGCT samples from carriers. This is the first demonstration of the involvement of a PDE gene in TGCT, although the cyclic AMP signaling pathway has been investigated extensively in reproductive organ function and their diseases. In conclusion, we report that PDE11A-inactivating sequence variants may modify the risk of familial and bilateral TGCT.

Notch is an interesting candidate that has only been correlated with melanoma development and progression; a thorough assessment of tumor-initiating effects of activated Notch on human melanocytes would clarify the mounting correlative evidence and perhaps identify a novel target for an otherwise untreatable disease. Analysis of a substantial panel of cell lines and patient lesions showed that Notch activity is significantly higher in melanomas than their nontransformed counterparts. The use of a constitutively active, truncated Notch transgene construct (N(IC)) was exploited to determine if Notch activation is a "driving" event in melanocytic transformation or instead a "passenger" event associated with melanoma progression. N(IC)-infected melanocytes displayed increased proliferative capacity and biological features more reminiscent of melanoma, such as dysregulated cell adhesion and migration. Gene expression analyses supported these observations and aided in the identification of MCAM, an adhesion molecule associated with acquisition of the malignant phenotype, as a direct target of Notch trans-activation. N(IC)-positive melanocytes grew at clonal density, proliferated in limiting media conditions, and also exhibited anchorage-independent growth, suggesting that Notch alone is a transforming oncogene in human melanocytes, a phenomenon not previously described for any melanoma oncogene. This new information yields valuable insight into the basic epidemiology of melanoma and launches a realm of possibilities for drug intervention in this deadly disease.

TI Reviewing the current classification of inhibitor of growth family proteins SO CANCER SCIENCE LA English DT Review ID CANDIDATE TUMOR-SUPPRESSOR; CELL-CYCLE ARREST; HISTONE H3K4ME3 RECOGNITION; PHD FINGER PROTEINS; ALTERNATIVE TRANSCRIPTS; ING1 GENE; REPLICATIVE SENESCENCE; DEACETYLASE COMPLEX; PLANT HOMEODOMAIN; GENOMIC STRUCTURE AB Inhibitor of growth (ING) family proteins have been defined as candidate tumor suppressors for more than a decade. Recent emerging results using siRNA and knockout mice are expanding the previous understanding of this protein family. The results of ING1 knockout mouse experiments revealed that ING1 has a protective effect on apoptosis. Our recent results showed that ING2 is overexpressed in colorectal cancer, and induces colon cancer cell invasion through an MMP13-dependent pathway. Knockdown of ING2 by siRNA induces premature senescence in normal human fibroblast cells, and apoptosis or cell cycle arrest in various adherent cancer cells. Taken together, these results suggest that ING2 may also have roles in cancer progression and/or malignant transformation under some conditions. Additionally, knockdown of ING4 and ING5 by siRNA shows an inhibitory effect on the transition from G(2)/M to G(1) phase and DNA replication, respectively, suggesting that these proteins may play roles during cell proliferation in some context. ING family proteins may play dual roles, similar to transforming growth factor-beta, which has tumor suppressor-like functions in normal epithelium and also oncogenic functions in invasive metastatic cancers. In the present article, we briefly review ING history and propose a possible interpretation of discrepancies between past and recent data.

Recently, we reported that this metabolite suppressed the expression of lipopolysaccharide-induced proinflammatory genes in murine macrophages by disrupting mitogen-activated protein kinases and Akt pathways. In this study, we investigated the inhibitory effects of 13-HOA on 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced inflammation in ears and skin, as well as tumor promotion in female ICR mice. Pretreatment with 13-HOA (1600 nmol) inhibited ear edema formation by 95% (P < 0.05) in an inflammation test and reduced tumor incidence and the number of tumors per mouse by 40 and 64% (P < 0.05 each), respectively, in a two-stage skin carcinogenesis model. Histological examinations revealed that it decreased epidermal thickness, the number of infiltrated leukocytes and cell proliferation index. Furthermore, 13-HOA (8-40 mu M) suppressed TPA-induced anchorage-independent growth of JB6 mouse epidermal cells by 70-100%, whereas LA was virtually inactive. 13-HOA (40 mu M) inhibited TPA-induced activator protein-1 transactivation but not extracellular signal-regulated kinase1/2 activation. Interestingly, 13-HOA (40 mu M and 1600 nmol in JB6 cells and mouse skin, respectively) induced expression of programmed cell death 4 (Pdcd4), a novel tumor suppressor protein. To our knowledge, this is the first report of a food factor that is able to induce Pdcd4 expression. Collectively, our results indicate that 13-HOA may be a novel anti-inflammatory and antitumor chemopreventive agent with a unique mode of action.

TI EphrinB reverse signaling in cell-cell adhesion Is it just par for the course? SO CELL ADHESION & MIGRATION LA English DT Article DE ephrin; Eph; cell-cell adhesion; Par-6; tight junctions AB Cell-cell adhesion is a critical process for the formation and maintenance of tissue patterns during development, as well as invasion and metastasis of cancer cells. Although great strides have been made regarding our understanding of the processes that play a role in cell-cell adhesion, the precise mechanisms by which diverse signaling events regulate cell and tissue architecture is poorly understood. In this commentary we will focus on the Eph/ephrin signaling system, and specifically how the ephrinB1 transmembrane ligand for Eph receptor tyrosine kinases sends signals affecting cell-cell junctions. In a recent study using the epithelial cells of early stage Xenopus embryos, we have shown that loss-or gain-of function of ephrinB1 can disrupt cell-cell contacts and tight junctions. This study reveals a mechanism where ephrinB1 competes with active Cdc42 for binding to Par-6, a scaffold protein central to the Par polarity complex (Par-3/Par-6/Cdc42/aPKC) and disrupts the localization of tight junction-associated proteins (ZO-1, Cingulin) at tight junctions. This competition reduces aPKC activity critical to maintaining and/or forming tight junctions. Finally, phosphorylation of ephrinB1 on specific tyrosine residues can block the interaction between ephrinB1 and Par-6 at tight junctions, and restore tight junction formation. Recent evidence indicates that de-regulation of forward signaling through EphB receptors may play a role in metastatic progression in colon cancer. In light of the new data showing an effect of ephrinB reverse signaling on tight junctions, an additional mechanism can be hypothesized where de-regulation of ephrinB1 expression or phosphorylation may also impact metastatic progression.

TI Adhesion- and migration-related side effects of phosphothioated CpG oligodeoxynucleotides SO CELL ADHESION & MIGRATION LA English DT Article DE ECM; CpG; toll-like receptors; neurons; adhesion; phosphothioated; oligodeoxynucleotides AB Nucleic acid oligodeoxynucleotides (ODN) are increasingly used in biological research and in clinics where they are used for both diagnostic and therapeutic purposes. In order to increase the stability and efficacy of ODNs, various chemical modifications have been applied to create nucleic acid derivatives that are not recognized by endogenous nucleic acid cleavage mechanisms. One of the most common and cost-effective modifications is the phosphothioate (PTO) modification. The PTO modification is implemented mainly in antisense ODN, but also in ODN that were shown to activate members of the toll-like receptor (TLR) family such as TLR3 (poly-I:C), TLR8 (ssRNA) and TLR9 (CpG). We recently found that PTO-ODN aimed at activating TLR9 induce a non-TLR9-specific detachment phenotype in a growth-substrate dependent manner. Moreover, we found that unmodified and PTO-modified TLR ligands induce distinct patterns of gene expression in cultured neural cells. These findings suggest that PTO-ODN can cause nonspecific effects on cell adhesion that could compromise interpretation of data from experiments using PTO-ODN.

These proteins form ion channels through which store-operated Ca2+ influx (SOC) occurs. Calcium ions exert negative feedback on SOC. Here we examined whether subplasmalemmal mitochondria, which reduce this feed-back by Ca2+ uptake, are located within or out of the high-Ca2+ microdomains (HCMDs) formed between the ER and plasmalemmal Orai1 channels. For this purpose, COS-7 cells were cotransfected with Orai1, STIM1 labelled with YFP or mRFP and the mitochondrially targeted Ca2+ sensitive fluorescent protein inverse-Pericam. Depletion of ER Ca2+ with ATP + thapsigargin (in Ca2+-free medium) induced the appearance of STIM1 puncta in the <= 100 nm wide subplasmalemmal space, as examined with TIRE Mitochondria were located either in the gaps between STIM1-tagged puncta or in remote, STIM1-free regions. After addition of Ca2+ mitochondrial Ca2+ concentration increased irrespective of the mitochondrion-STIM1 distance. These observations indicate that mitochondria are exposed to Ca2+ diffused laterally from the HCMDs formed between the PM and the subplasmalemmal ER. (C) 2009 Elsevier Ltd. All rights reserved.

Tumor cells harboring MET gene amplification are initially sensitive to c-Met tyrosine kinase inhibitors (TKI), but escape from long-term treatment has not been investigated. C-Met is a client of heat shock protein 90 (Hsp90) and is destabilized by Hsp90 inhibitors, suggesting that these drugs may inhibit tumors driven by MET amplification, although tumor escape under these conditions also has not been explored. Here, we evaluated the initial inhibitory effects of, and the likelihood of escape from, the Hsp90 inhibitor 17-allylamino-17-demethoxy-geldanamycin (17-AAG) and the c-Met TKI SU11274, using two cell lines harboring MET gene amplification. 17-AAG inhibited cell growth in both cell lines and induced substantial apoptosis, whereas SU11274 was only growth inhibitory in one cell line. In both cell lines, c-Met-dependent Akt, Erk and/or STAT3 signaling, as well as activation of the EGFR family, resumed shortly after treatment with c-Met TKI despite sustained c-Met inhibition. PKC delta upregulation may participate in reactivation of c-Met downstream signaling in both cell lines. In contrast to c-Met TKI, 17-AAG destabilized c-Met protein and durably blocked reactivation of downstream signaling pathways and EGFR family members. Our data demonstrate that downstream signaling in tumor cells overexpressing c-Met is not stably suppressed by c-Met TKI, even though c-Met remains fully inhibited. In contrast, Hsp90 inhibitors provide long-lasting suppression of c-Met-dependent signaling, and these drugs should be further evaluated in tumors driven by MET gene amplification.

Several studies reveal multiple pathways linking NF kappa B to the promotion and progression of various cancers. Despite extensive interest and characterization, many NF kappa B controlled genes still remain to be identified. We used chromatin immunoprecipitation combined with microarray technology (ChIP/chip) to investigate the dynamic interaction of NF kappa B with the promoter regions of 100 genes known to be expressed in mitogen-induced T-cells. Six previously unrecognized NF kappa B controlled genes (ATM, EP300, TGF beta, Selectin, MMP-1 and SFN) were identified. Each gene is induced in mitogen-stimulated T-cells, repressed by pharmacological NF kappa B blockade, reduced in cells deficient in the p50 NF kappa B subunit and dramatically repressed by RNAi specifically designed against cRel. A coregulatory role for Ets transcription factors in the expression of the NF kappa B controlled genes was predicted by comparative promoter analysis and confirmed by ChIP and by functional disruption of Ets. NF kappa B deficiency produces a deficit in ATM function and DNA repair indicating an active role for NF kappa B in maintaining DNA integrity. These results define new potential targets and transcriptional networks governed by NF kappa B and provide novel functional insights for the role of NF kappa B in genomic stability, cell cycle control, cell-matrix and cell-cell interactions during tumor progression.

Here we have performed a global transcriptional profiling of the highly virulent F. tularensis ssp. tularensis Schu S4 strain during its intracellular cycle within primary murine macrophages, to characterize its intracellular biology and identify pathogenic determinants based on their intracellular expression profiles. Phagocytosed bacteria rapidly responded to their intracellular environment and subsequently altered their transcriptional profile. Differential gene expression profiles were revealed that correlated with specific intracellular locale of the bacteria. Upregulation of general and oxidative stress response genes was a hallmark of the early phagosomal and late endosomal stages, while induction of transport and metabolic genes characterized the cytosolic replication stage. Expression of the Francisella Pathogenicity Island (FPI) genes, which are required for intracellular proliferation, increased during the intracellular cycle. Similarly, 27 chromosomal loci encoding putative hypothetical, secreted, outer membrane proteins or transcriptional regulators were identified as upregulated. Among these, deletion of FTT0383, FTT0369c or FTT1676 abolished the ability of Schu S4 to survive or proliferate intracellularly and cause lethality in mice, therefore identifying novel determinants of Francisella virulence from their intracellular expression profile.

We characterized the kinetics of Arf GAP2 and its regulation. Purified Arf GAP2 had little activity compared to purified Arf GAP1. Of the potential regulators we examined, coatomer had the greatest effect, stimulating activity one to two orders of magnitude. The effect was biphasic, with half-maximal activation observed at 50 nM coatomer and activation peaking at approximate to 150 nM coatomer. Activation by coatomer was greater for Arf GAP2 than has been reported for Arf GAP1. The effects of phosphoinositides and changes in vesicle curvature on GAP activity were small compared to coatomer; however, both increased coatomer-dependent activity. Peptides from p24 cargo proteins increased Arf GAP2 activity by an additional 2- to 4-fold. The effect of cargo peptide was dependent on coatomer. Overexpressing the cargo protein p25 decreased cellular Arfl.GTP levels. The differential sensitivity of Arf GAP1 and Arf GAP2 to coatomer could coordinate their activities. Based on the common regulatory features of Arf GAP1 and 2, we propose a mechanism for cargo selection in which GTP hydrolysis triggered by cargo binding to the coat protein is coupled to coat polymerization.

In this study, a series of protein kinase C (PKC) activators were investigated, some of which also exhibit histone deacetylase (HDAC) inhibitory activity, under the hypothesis that such compounds might provide a new path forward in the discovery of drugs for the treatment of AD. The PKC-activating properties of these drugs were expected to enhance the alpha-secretase pathway in the processing of amyloid precursor protein (APP), while their HDAC inhibition was anticipated to confer neuroprotective activity. We found that benzolactams 9 and 11-14 caused a concentration-dependent increase in sAPP alpha, and decrease in beta-amyloid (A beta) production in the concentration range of 0.1-10 mu M, consistent with a shift of APP metabolism toward the alpha-secretase-processing pathway. Moreover, compounds 9-14 showed neuroprotective effects in the 10-20 mu M range in the homocysteate (HCA) cortical neuron model of oxidative stress. In parallel, we found that the most neuroprotective compounds caused increased levels of histone acetylation (H4), thus indicating their likely ability to inhibit HDAC activity. As the majority of the compounds studied also show nanomolar binding affinities for PKC, we conclude that it is possible to design, de novo, agents that combine both PKC-activating properties along with HDAC inhibitory properties. Such agents would be capable of modulating amyloid processing while showing neuroprotection. These findings may offer a new approach to therapies that exhibit disease-modifying effects, as opposed to symptomatic relief, in the treatment of AD.

Participants appraised how unfamiliar peers they had previously identified as being of high or low interest would evaluate them for an anticipated online chat session. Differential age- and sex-related activation patterns emerged in several regions previously implicated in affective processing. These included the ventral striatum, hippocampus, hypothalamus, and insula. In general, activation patterns shifted with age in older relative to younger females but showed no association with age in males. Relating these neural response patterns to changes in adolescent social-cognition enriches theories of adolescent social development through enhanced neurobiological understanding of social behavior.

Anilines were treated with acetic anhydride and triethylamine in dry CH(2)Cl(2) to give the corresponding acetamides. The subsequent N-monomethylation of acetyl aryl amines with methyl iodide and NaH in THF introduced methyl group. Acid hydrolysis of the N-methyl acetanilides in ethylene glycol generated the corresponding N-methyl-N-aryl amines in high yields. This method was also used to synthesize (E)-2-bromo-5-(4-methylaminostyryl)pyridine that may be useful as an amyloid imaging agent for Alzheimer's disease.

If dosage compensation mechanisms completely suppressed the 2nd X chromosome, then actual physical loss of this "eXtra" chromosome should have few consequences. However, X monosomy has major effects upon normal development, fertility and longevity in humans and some other species. This article reviews observations and arguments attempting to explain the phenotypic effects of X monosomy in humans and other mammals in terms of X chromosome gene dosage.

Such a comparison poses challenges, not only because the two diseases differ in the domains of functioning affected, but also because of the different instruments used to measure functional limitations. Limiting our analysis to studies using similar self-report questionnaires, we examined published observational studies of unselected cohorts of patients with RA and patients with AS to compare and contrast the severity of functional limitations. Available studies from a few direct comparisons, and mostly indirect comparions, suggested that patients with RA are generally more severely limited in physical functioning throughout the disease course than patients with AS. Since mose studies did not adjust adequately for potentially important confounders. Such as age, gender, comorbidity, and disease duration, reported differences in functional disability between patients with RA and patients with AS must be interpreted cautiously. C1 [Louie, G.

TI Anti-Apical-Membrane-Antigen-1 Antibody Is More Effective than Anti-42-Kilodalton-Merozoite-Surface-Protein-1 Antibody in Inhibiting Plasmodium falciparum Growth, as Determined by the In Vitro Growth Inhibition Assay SO CLINICAL AND VACCINE IMMUNOLOGY LA English DT Article ID APICAL MEMBRANE ANTIGEN-1; MEROZOITE SURFACE PROTEIN-1; MALARIA VACCINE CANDIDATE; BLOOD-STAGE VACCINE; MONTANIDE ISA 720; IMMUNOGENICITY TRIAL; KENYAN CHILDREN; CLINICAL-TRIAL; AMA1 VACCINE; SAFETY AB Apical membrane antigen 1 (AMA1) and the 42-kDa merozoite surface protein 1 (MSP1(42)) are leading malaria vaccine candidates. Several preclinical and clinical trials have been conducted, and an in vitro parasite growth inhibition assay has been used to evaluate the biological activities of the resulting antibodies. In a U.S. phase 1 trial with AMA1-C1/Alhydrogel plus CPG 7909, the vaccination elicited anti-AMA1 immunoglobulin G (IgG) which showed up to 96% inhibition. However, antibodies induced by MSP1(42)-C1/Alhydrogel plus CPG 7909 vaccine showed less than 32% inhibition in vitro. To determine whether anti-MSP1(42) IgG had less growth-inhibitory activity than anti-AMA1 IgG in vitro, the amounts of IgG that produced 50% inhibition of parasite growth (Ab(50)) were compared for rabbit and human antibodies. The Ab(50)s of rabbit and human anti-MSP1(42) IgGs were significantly higher (0.21 and 0.62 mg/ml, respectively) than those of anti-AMA1 IgGs (0.07 and 0.10 mg/ml, respectively) against 3D7 parasites. Ab(50) data against FVO parasites also demonstrated significant differences. We further investigated the Ab(50)s of mouse and monkey anti-AMA1 IgGs and showed that there were significant differences between the species (mouse, 0.28 mg/ml, and monkey, 0.14 mg/ml, against 3D7 parasites). Although it is unknown whether growth-inhibitory activity in vitro reflects protective immunity in vivo, this study showed that the Ab(50) varies with both antigen and species. Our data provide a benchmark for antibody levels for future AMA1- or MSP1(42)-based vaccine development efforts in preclinical and clinical trials.

TI Development of a Murine Mycobacterial Growth Inhibition Assay for Evaluating Vaccines against Mycobacterium tuberculosis SO CLINICAL AND VACCINE IMMUNOLOGY LA English DT Article ID TUMOR-NECROSIS-FACTOR; CD4(+) T-CELLS; IN-VITRO; INTRACELLULAR GROWTH; PROTECTIVE IMMUNITY; INTERFERON-GAMMA; CALMETTE-GUERIN; INFECTION; MICE; BCG AB The development and characterization of new tuberculosis (TB) vaccines has been impeded by the lack of reproducible and reliable in vitro assays for measuring vaccine activity. In this study, we developed a murine in vitro mycobacterial growth inhibition assay for evaluating TB vaccines that directly assesses the capacity of immune splenocytes to control the growth of Mycobacterium tuberculosis within infected macrophages. Using this in vitro assay, protective immune responses induced by immunization with five different types of TB vaccine preparations (Mycobacterium bovis BCG, an attenuated M. tuberculosis mutant strain, a DNA vaccine, a modified vaccinia virus strain Ankara [MVA] construct expressing four TB antigens, and a TB fusion protein formulated in adjuvant) can be detected. Importantly, the levels of vaccine-induced mycobacterial growth-inhibitory responses seen in vitro after 1 week of coculture correlated with the protective immune responses detected in vivo at 28 days postchallenge in a mouse model of pulmonary tuberculosis. In addition, similar patterns of cytokine expression were evoked at day 7 of the in vitro culture by immune splenocytes taken from animals immunized with the different TB vaccines. Among the consistently upregulated cytokines detected in the immune cocultures are gamma interferon, growth differentiation factor 15, interleukin-21 (IL-21), IL-27, and tumor necrosis factor alpha. Overall, we have developed an in vitro functional assay that may be useful for screening and comparing new TB vaccine preparations, investigating vaccine-induced protective mechanisms, and assessing manufacturing issues, including product potency and stability.

Expression of met, a receptor tyrosine kinase, has been associated with progression of prostate cancer. Experimental Design: To investigate met as a biomarker of disease progression, urinary met was evaluated via ELISA in men with localized (n = 75) and metastatic (n = 81) prostate cancer. Boxplot analysis was used to compare the distribution of met values between each group. We estimated a receiver operating characteristic curve and the associated area under the curve to summarize the diagnostic accuracy of met for distinguishing between localized and metastatic disease. Protein-protein interaction networking via yeast two-hybrid technology supplemented by Ingenuity Pathway Analysis and Human Interactome was used to elucidate proteins and pathways related to met that may contribute to progression of disease. Results: Met distribution was significantly different between the metastatic group and the group with localized prostate cancer and people with no evidence of cancer (P < 0.0001). The area under the curve for localized and metastatic disease was 0.90, with a 95% confidence interval of 0.84 to 0.95. Yeast two-hybrid technology, Ingenuity Pathway Analysis, and Human Interactome identified 89 proteins that interact with met, of which 40 have previously been associated with metastatic prostate cancer. Conclusion: Urinary met may provide a noninvasive biomarker indicative of metastatic prostate cancer and may be a central regulator of multiple pathways involved in prostate cancer progression.

Ensuring the accuracy and reproducibility of HER2 assays by immunohistochemistry (IHC) and by fluorescence in situ hybridization (FISH) requires a reliable standard for monitoring assay sensitivity and specificity, and for assessing methodologic variation. A prior NIST workshop addressed this need by reaching a consensus to create cell lines as reference materials for HER2 testing. METHODS: Breast carcinoma cell lines SK-BR-3 and MCF-7 were characterized quantitatively by IHC with chicken anti-HER2 IgY antibody and by FISH with biotinylated bacterial artificial chromosome DNA probes; both assays used quantum dots as detectors. Formalin-fixed and paraffin-embedded (FFPE) cell blocks were prepared and tested for suitability as candidate reference materials by IHC and FISH with commercially available reagents. IHC and FISH results were also compared with those obtained by laser-scanning cytometry and real-time PCR, respectively. RESULTS: MCF-7 cells had typical numbers of gene copies and very low production of HER2 protein, whereas SK-BR-3 cells contained approximately 10-fold more copies of the gene and exhibited approximately 15-fold higher amounts of HER2 protein than MCF-7 cells. FFPE SK-BR-3 cells showed results similar to those for fresh SK-BR-3 cells. CONCLUSIONS: SK-BR-3 and MCF-7 are suitable as candidate reference materials in QC of HER2 testing. Coupled with the associated assay platforms, they provide valuable controls for quantitative measurement of HER2 amplification and production in breast cancer samples, irrespective of the antibody/probe or detector used.

Our aim was to investigate the yield of F-18-FDA PET vs. biochemical testing and other imaging techniques to establish the diagnosis and location of PHEO. Patients and measurements The study included 99 consecutive patients (35 Males, 64 Females, mean +/- SD age 46 center dot 4 +/- 13 center dot 4 years), who underwent F-18-FDA PET, biochemical testing (plasma catecholamines and free metanephrines) and CT and/or MRI. The majority (78%) also underwent I-123/131-MIBG. Results In total 26 patients had non-metastatic PHEO, 34 patients had metastatic PHEO, and PHEO was ruled out in 39 patients. Investigations to rule out or confirm PHEO yielded the following sensitivity/specificity: plasma metanephrines 97/95%, F-18-FDA 92/90%, I-123-MIBG 83/100%, I-123/131-MIBG 70/100%, CT 100/41%, MRI 98/60%. Sensitivities for localizing non-metastatic PHEO on a per-lesion base were: CT 97%, MRI 92%, F-18-FDA 78%, I-123-MIBG 78% and I-123/131-MIBG 76%. Sensitivities for detecting metastases on a per-patient base were: CT and MRI 100%, F-18-FDA 97%, I-123-MIBG 85% and I-123/131-MIBG 65%. Conclusion For tumour localization, F-18-FDA PET and I-123/131-MIBG scintigraphy perform equally well in patients with non-metastatic PHEO, but metastases are better detected by F-18-FDA PET than by I-123/131-MIBG.

TI Strong IgG antibody responses to Borrelia burgdorferi glycolipids in patients with Lyme arthritis, a late manifestation of the infection SO CLINICAL IMMUNOLOGY LA English DT Article DE Lyme disease; Bacterial infection; Borrelia burgdorferi; Antibodies; Glycolipid antigens ID T-CELLS; CHOLESTERYL GALACTOSIDE; DISEASE; RECOMBINANT; ANTIGENS; PEPTIDE; VACCINE AB In this study, the membrane lipids of B. burgdorferi were separated into 16 fractions; the components in each fraction were identified, and the immunogenicity of each fraction was determined by ELISA using sera from Lyme disease patients. Only the 2 glycolipids, acylated cholesteryl galactoside (ACG, BbGL-I) and monogalactosyl diacylglycerol (MgaID, BbGL-II), were immunogenic. Early in the infection, 24 of 84 patients (29%) who were convalescent from erythema migrans and 19 of the 35 patients (54%) with neuroborreliosis had weak IgG responses to purified MgaID, and a smaller percentage of patients had early responses to synthetic ACG. However, almost all of 75 patients with Lyme arthritis, a late disease manifestation, had strong IgG reactivity with both glycolipids. Thus, almost all patients with Lyme arthritis have strong IgG antibody responses to B. burgdorferi glycolipid antigens. (C) 2009 Elsevier Inc. All rights reserved.

TI Invasive Aspergillosis Due to Neosartorya udagawae SO CLINICAL INFECTIOUS DISEASES LA English DT Article ID CHRONIC GRANULOMATOUS-DISEASE; PULMONARY ASPERGILLOSIS; AMPHOTERICIN-B; IMMUNOCOMPROMISED PATIENTS; IN-VITRO; FUMIGATUS; FISCHERI; TRANSPLANT; INFECTION; THERAPY AB Background. Invasive aspergillosis (IA) is most commonly caused by the morphospecies Aspergillus fumigatus. However, genetic-based methods indicate that organisms phenotypically identified as A. fumigatus actually constitute a mold complex, designated Aspergillus section fumigati subgenus fumigati. Methods. Multilocus sequencing and analysis was performed on fungi identified as A. fumigatus from the clinical culture collection maintained at the National Institutes of Health from 2000 through 2008, with a focus on the internal transcribed spacer 1 and 2 regions of ribosomal DNA (rDNA), beta-tubulin, and rodlet A genes. We reviewed the medical records, radiology, and histopathology of corresponding patients. To confirm identification of Neosartorya udagawae isolates, mating studies were performed with reference strains. Antifungal susceptibility testing was performed by broth microdilution and read at 48 hours. Results. Thirty-six cases of infection attributed to A. fumigatus were identified; 4 were caused by N. udagawae (3 in patients with chronic granulomatous disease and 1 in a patient with myelodysplastic syndrome). Disease due to N. udagawae was chronic, with a median duration of 35 weeks, compared with a median duration of 5.5 weeks for patients with chronic granulomatous disease who had infection due to A. fumigatus sensu stricto (P < .05 Mann-Whitney U test). Infection spread across anatomical planes in a contiguous manner and was refractory to standard therapy. Two of the 4 patients died. N. udagawae demonstrated relatively higher minimum inhibitory concentrations to various agents, compared with those demonstrated by contemporary A. fumigatus sensu stricto isolates. Conclusions. To our knowledge, this is the first report documenting infection due to N. udagawae. Clinical manifestations were distinct from those of typical IA. Fumigati-mimetics with inherent potential for antifungal resistance are agents of IA. Genetic identification of molds should be considered for unusual or refractory IA.
