TI Chlorhexidine Gluconate Reduces Transmission of Methicillin-Resistant Staphylococcus aureus USA300 among Marine Recruits SO INFECTION CONTROL AND HOSPITAL EPIDEMIOLOGY LA English DT Article ID BLOOD-STREAM INFECTIONS; FIELD GEL-ELECTROPHORESIS; SOFT-TISSUE INFECTIONS; UNITED-STATES; MOLECULAR EPIDEMIOLOGY; NASAL COLONIZATION; DOUBLE-BLIND; SKIN; TRIAL; SUSCEPTIBILITIES AB BACKGROUND. Methicillin-resistant Staphylococcus aureus (MRSA) pulsed-field type (PFT) USA300 causes skin and soft tissue infections in military recruits and invasive disease in hospitals. Chlorhexidine gluconate (CHG) is used to reduce MRSA colonization and infection. The impact of CHG on the molecular epidemiology of MRSA is not known. OBJECTIVE. To evaluate the impact of 2% CHG-impregnated cloths on the molecular epidemiology of MRSA colonization. DESIGN. Cluster-randomized, double-blind, controlled trial. SETTING. Marine Officer Candidate School, Quantico, Virginia, in 2007. PARTICIPANTS. Military recruits. INTERVENTION. Thrice-weekly application of CHG-impregnated or control (Comfort Bath; Sage) cloths over the entire body. MEASUREMENTS. Baseline and serial (every 2 weeks) nasal and/or axillary swab samples were assessed for MRSA colonization. Molecular analysis was performed with pulsed-field gel electrophoresis. RESULTS. During training, 77 subjects (4.9%) acquired MRSA, 26 (3.3%) in the CHG group and 51 (6.5%) in the control group (). When analyzed for PFT, 24 Pp. 004 subjects (3.1%) in the control group but only 6 subjects (0.8%) in the CHG group (Pp. 001) had USA300. Of the 167 colonizing isolates recovered from 77 subjects, 99 were recovered from the control group, including USA300 (40.4%), USA800 (38.4%), USA1000 (12.1%), and USA100 (6.1%), and 68 were recovered from the CHG group, including USA800 (51.5%), USA100 (23.5%), and USA300 (13.2%). CONCLUSIONS. CHG decreased the transmission of MRSA-more specifically, USA300-among military recruits. In addition, USA300 and USA800 outcompeted other MRSA PFTs at incident colonization. Future studies should evaluate the broad-based use of CHG to decrease transmission of USA300 in hospital settings.

TI Vaccine-derived NSP2 segment in rotaviruses from vaccinated children with gastroenteritis in Nicaragua SO INFECTION GENETICS AND EVOLUTION LA English DT Article DE Rotavirus; Genomics; Vaccine; RotaTeq ID POLYMERASE CHAIN-REACTION; CRYOELECTRON MICROSCOPY; GENOME REPLICATION; SEVERE DIARRHEA; VP7; STRAINS; PROTEIN; INFANTS; ACID; NEUTRALIZATION AB Rotavirus (RV) vaccination programs have been established in several countries using the human-attenuated G1P[8] monovalent vaccine Rotarix (TM) (GlaxoSmithKline) and/or the human-bovine reassortant G1, G2, G3, G4, P[8] pentavalent vaccine Rotaleq (TM) (Merck). The efficacy of both vaccines is high (similar to 90%) in developed countries, but can be remarkably lower in developing countries. For example, a vaccine efficacy against severe diarrhea of only 58% was observed in a 2007-2009 Nicaraguan study using RotaTeq. To gain insight into the significant level of vaccine failure in this country, we sequenced the genomes of RVs recovered from vaccinated Nicaraguan children with gastroenteritis. The results revealed that all had genotype specificities typical for human RVs (11G1P[8], 1G3P[8]) and that the sequences and antigenic epitopes of the outer capsid proteins (VP4 and VP7) of these viruses were similar to those reported for RVs isolated elsewhere in the world. As expected, nine of the G1 P[8] viruses and the single G3P[8] virus had genome constellations typical of human G1 P[8] and G3P[8] RVs: G1/3-P[8]-I1-R1-C1-M1-A1-N1-T1-E1-H1. However, two of the G1P[8] viruses had atypical constellations, G1-P[8]-I1-R1-C1-M1-A1-N2-T1-E1-H1, due to the presence of a genotype-2 NSP2 (N2) gene. The sequence of the N2 NSP2 gene was identical to the bovine N2 NSP2 gene of RotaTeq, indicating that the two atypical viruses originated via reassortment of human G1P[8] RVs with RotaTeq viruses. Together, our data suggest that the high level of vaccine failure in Nicaraguan is probably not due to antigenic drift of commonly circulating virus strains nor the emergence of new antigenetically distinct virus strains. Furthermore, our data suggest that the widespread use of the RotaTeq vaccine has led to the introduction of vaccine genes into circulating human RVs. Published by Elsevier B.V.

TI A Novel STAT1 Mutation Associated with Disseminated Mycobacterial Disease SO JOURNAL OF CLINICAL IMMUNOLOGY LA English DT Article DE STAT1; SH2 domain; mycobacterial disease; IFN-gamma ID DEFICIENCY; RESPONSES; IMMUNITY; PHOSPHORYLATION; INTERFERONS; IMPAIRMENT; ACTIVATION; PATIENT; DOMAIN; GAMMA AB STAT1 is a key component of Interferon (IFN)-gamma and IFN-alpha signaling and mediates protection against mycobacteria, fungal, viral infections, and cancer. Dominant negative inhibitory as well as gain of function heterozygous STAT1 mutations demonstrate that IFN-gamma driven cellular responses need to be tightly regulated to control infections. We describe an autosomal dominant mutation in the SH2 domain of STAT1 that disrupts protein phosphorylation, c.1961T > A (M654K). The mutant allele does not permit STAT1 phosphorylation, and impairs STAT1 phosphorylation of the wild type allele. Protein dimerization is preserved but DNA binding activity, IFN-gamma driven GAS-luciferase activity, and expression of IFN-gamma target genes are reduced. IFN-alpha driven ISRE response, but not IFN-alpha driven GAS response, are preserved when cells are co-transfected with wild type and the mutant STAT1 constructs. M654K exerts a dominant negative effect on IFN-gamma related immunity and is recessive for IFN-alpha induced immune function.

Three patients presented with typical features of recurrent or severe cutaneous viral infections, atopic dermatitis, and recurrent respiratory or gastrointestinal tract infections. However, four patients presented with other features. Patient 1-1 featured sclerosing cholangitis and colitis; patient 2-1, granulomatous soft tissue lesion and central nervous system involvement, with primary central nervous system lymphoma found on follow-up; patient 3-1, a fatal metastatic leiomyosarcoma; and patient 4-2 showed no other symptoms initially besides atopic dermatitis. Similar to other previously reported Turkish patients, but in contrast to patients of non-Turkish ethnicity, the patients' lymphopenia was primarily restricted to CD4(+) T cells. Patients had homozygous mutations in DOCK8 that altered splicing, introduced premature terminations, destabilized protein, or involved large deletions within the gene. Genotyping of remaining family members showed that DOCK8 deficiency is a fully penetrant, autosomal recessive disease. In our patients, bone marrow transplantation resulted in rapid improvement followed by disappearance of viral skin lesions, including lesions resembling epidermodysplasia verruciformis, atopic dermatitis, and recurrent infections. Particularly for patients who feature unusual clinical manifestations, immunological testing, in conjunction with genetic testing, can prove invaluable in diagnosing DOCK8 deficiency and providing potentially curative treatment.

TI Enhancing Image Analytic Tools by Fusing Quantitative Physiological Values with Image Features SO JOURNAL OF DIGITAL IMAGING LA English DT Article DE Data fusion; Physiological values; Multimodal biomarkers; Computer-aided diagnosis; Pulmonary fibrosis ID COMPUTER-AIDED DIAGNOSIS; PULMONARY-FIBROSIS; CLASSIFICATION; LUNG; CT AB Computer-aided diagnosis systems (CADs) can quantify the severity of diseases by analyzing a set of images and employing prior statistical models. In general, CADs have proven to be effective at providing quantitative measurements of the extent of a particular disease, thus helping physicians to better monitor the progression of cancer, infectious diseases, and other health conditions. Electronic Health Records frequently include a large amount of clinical data and medical history that can provide critical information about the underlying condition of a patient. We hypothesize that the fusion of image and clinical-physiological features can be used to enhance the accuracy of automatic image classification models. In particular, this paper shows how image analytic tools can move beyond classical image interpretation models to broader systems where image and physiological measurements are fused and used to create more generic detection models. To test our hypothesis, a CAD system capable of quantifying the severity of patients with pulmonary fibrosis has been developed. Results show that CAD systems augmented with multimodal physiological values are more robust and accurate at determining the severity of the disease.

In this study we explore age-based variations in causal beliefs for heart disease and diabetes among Mexican origin adults in Houston, TX. This cross-sectional study included 497 adults of Mexican origin. Participants were asked to indicate the importance of biomedically defined and folk illness-related risk factors as causes for heart disease and diabetes. Biomedical risk factors were ranked highest as causes of diabetes and heart disease among all participants. Folk illness-related factors were ranked below biomedical factors as causes of heart disease among all age groups. Susto was ranked above the median as a risk factor for diabetes among older participants. Age-related differences in causal beliefs may have implications for designing culturally appropriate health services, such as tailored diabetes interventions for older Mexican origin adults.

The emergence of new genetic variants of WNV represents an important public health issue because it may affect the sensitivity of WNV screening and diagnostic assays, as well as the development and efficacy of WNV vaccines and anti-viral drugs. A microarray assay was developed and optimized to enable simple monitoring of WNV genetic variability and rapid detection of any nucleotide mutations within the entire viral genome. The assay was validated using 11 WNV isolates from the 2007 and 2009 U.S. epidemics. The developed microarray system can potentially serve as a high throughput, rapid, and effective approach for the detection of circulating WNV genetic variants. Published by Elsevier B.V.

TI Directed therapy for patients with myelodysplastic syndromes (MDS) by suppression of cyclin D1 with ON 01910.Na SO LEUKEMIA RESEARCH LA English DT Article DE MDS; Treatment; ON 01910.Na; Cyclin D1 ID SCORING SYSTEM; UP-REGULATION; CD34 CELLS; PHASE-I; EXPRESSION; TRISOMY-8; SURVIVAL; LEUKEMIA; EFFICACY; ABNORMALITIES AB Background: We previously demonstrated upregulation of c-myc, survivin, and cyclin D1 in CD34+ bone marrow mononuclear cells (BMMNCs) of patients with trisomy 8 and monosomy 7 myelodysplastic syndromes (MDS). "Knockdown" of cyclin D1 by RNA interference decreased trisomy 8 cell growth, suggesting that this might be a therapeutic target in MDS. Experimental design: We performed preclinical studies using BMMNCs from patients with MDS and AML to examine the effects of the styryl sulfone ON 01910.Na on cyclin D1 accumulation, aneuploidy, and CD34+ blast percentage. We next treated twelve patients with higher risk MDS and two trisomy 8 AML patients with ON 01910.Na on a phase I clinical protocol (NCT00533416). Results: ON 01910.Na inhibited cyclin D1 expression, and was selectively toxic to trisomy 8 cells in vitro. Flow cytometry studies demonstrated increased mature CD15+ myeloid cells and decreased CD34+ blasts. Three patients treated with ON 01910.Na on a clinical had decreased bone marrow blasts by >= 50%, and three patients had hematologic improvements, one of which was sustained for 33 months. Patients with hematologic responses to ON 01910.Na had decreased cyclin D1 expression in their CD34+ cells. Conclusions: The preclinical results and responses of patients on a clinical trial warrant further investigation of ON 01910.Na as a potential novel targeted therapy for higher risk MDS patients.

Aberrant DNA methylation has been reported to silence the expression of tumor suppressor genes in leukemia. Overexpression of the histone methyltransferase, EZH2, a subunit of the polycomb group repressive complex 2 (PRC2), was observed to promote oncogenesis. This is due to aberrant gene silencing by the trimethylation of histone H3 lysine 27 (H3K27me3) by EZH2. Since both these epigenetic silencing events are reversible, they are interesting targets for chemotherapeutic intervention by using an inhibitor of DNA methylation, such as 5-aza-2'-deoxcytidine (5-AZA-CdR), and 3-deazaneplanocin-A (DZNep), an inhibitor of the EZH2. Human HL-60 and murine L1210 leukemic cells exposed in vitro to 5-AZA-CdR and DZNep in combination showed a synergistic loss of clonogenicity in a colony assay as compared to each agent alone. This positive chemotherapeutic interaction was also observed in mice with L1210 leukemia. Quantitative PCR showed that the combination also produced a remarkable synergistic activation of the tumor suppressor genes, CDKN1A and FBXO32. Microarray analysis showed that 5-AZA-CdR plus DZNep produced a synergistic activation of > 150 genes. Our results indicate that 5-AZA-CdR plus DZNep can reactivate target genes that are silenced by two distinct epigenetic mechanisms leading to a loss of the proliferative potential of leukemic cells.

Whether this is also the case for expertise in visual object recognition is unknown. Here we tested whether individual variability in the ability to recognize car models, from novice performance to high level of expertise, is associated with specific structural changes in gray matter volume. We found that inter-individual variability in expertise with cars was significantly and selectively correlated with gray matter volume in prefrontal cortex. Inter-individual differences in the recognition of airplanes, that none of the participants had expertise with, were correlated with structural variability of regions bordering the visual cortex. These results highlight the role of prefrontal regions outside the visual cortex in accessing and processing visual knowledge about objects from the domain of expertise and suggest that expertise in visual object recognition may entail structural changes in regions associated with semantic knowledge.

This study aims to identify the neuroimaging correlates of maintenance of higher global cognition as measured by the Modified Mini Mental State Test (3MS) score. Methods: Repeated 3MS measures from 1997-98 through 2006-07 and magnetic resonance imaging with diffusion tensor in 2006-07 were obtained in a biracial cohort of 258 adults free from dementia (mean age 82.9 years, 56% women, 42% blacks). Participants were classified as having shown either maintenance (3MS slope > 0) or decline (3MS slope <1 SD below the mean) of cognition using linear mixed models. Measures of interest were white matter hyperintensity volume (WMHv) from total brain, volume of the gray matter (GMv) and microstructure (mean diffusivity, MD) for total brain and for brain areas known to be related to memory and executive control function: medial temporal area (hippocampus, parahippocampus and entorhinal cortex), cingulate cortex, dorsolateral prefrontal and posterior parietal cortex. Results: Differences between cognitive maintainers (n = 153) and non-maintainers (n = 107) were significant for GMv of the medial temporal area (35.8%, p = 0.004) and lower MD of the cingulate cortex (37.9%, p = 0.008), but not for other neuroimaging markers. In multivariable regression models adjusted for age, race, WMHv and GMV from the total brain and vascular conditions, each standard deviation of GMv of the medial temporal area and each standard deviation of MD of the cingulate cortex were associated with a nearly 4 times greater probability (odds ratio [standard deviation]: 3.80 [1.16, 12.44]) and a 34% lower probability (0.66, [0.46, 0.97]) of maintaining cognitive function, respectively. In these models neither WMHv nor GMv from total brain were significantly associated with probability of maintaining cognitive function. Conclusions: Preserving the volume of the medial temporal area and the microstructure of the cingulate cortex may contribute to maintaining cognitive function late in life. (C) 2012 Elsevier Inc.

A 39-year-old female presented with a palpable mass present for 1 year in her left breast. Immunohistochemical staining was performed and the results showed that the tumor cells were immunopositive for the estrogen receptor, progesterone receptor and p53 protein, and markedly positive for C-erb B2. In addition,30% of the tumor cells were positive for the Ki-67 antigen. Blood test results revealed that EBV-CA-IgG was present and EBV-EA-IgG was reactivated. The patient was diagnosed with breast cancer (TIN0M0) and EBV infection. A mastectomy with axillary clearance was performed on the left breast. Histopathological examination provided evidence of invasive ductal adenocarcinoma. Further evaluation due to epistaxis following the breast surgery resulted in a diagnosis of nasopharyngeal carcinoma (T2N1M0). Histopathology showed a non-keratinizing undifferentiated carcinoma. The patient was treated with chemoradiotherapy for nasopharyngeal carcinoma. Twelve months following surgery and chemoradiotherapy the patient was assessed at the Cancer Hospital of Guangxi Medical University outpatient clinic and no evidence of relapse or metastasis was found. Thus, EBV infection may be involved in the pathogenesis of breast cancer, as observed in nasopharyngeal carcinoma.

Despite evidence for high heritability, conclusive genetic causes of schizophrenia remain elusive. Recent genomic technologies in concert with large case-control cohorts have led to several associations of highly penetrant rare copy number variants (CNVs) and schizophrenia. We previously reported two patients with COS who carried a microduplication disrupting the PXDN and MYT1L genes at 2p25.3. This rate of duplications within our COS population (N=92) is significantly higher than that in 2026 healthy controls (P=0.002). As a replication, we report a meta-analysis of four recently published studies that together provide strong evidence for an association between variably sized microduplications involving the MYT1L gene and schizophrenia. None have reported this separately. Altogether, among 5325 patients and 9279 controls, 10 microduplications were observed: nine in patients and one in a control (odds ratio = 15.7, P = 0.001). Further, the 2% rate observed in our COS patients is also significantly higher than the rate in adult-onset cases (0.14%, odds ratio = 16.6, P=0.01). This report adds to the growing body of literature implicating rare CNVs as risk factors for schizophrenia and shows that some risk CNVs are more common among extreme early-onset cases.

We have cloned the zebrafish nicotinic acetylcholine receptor (nAChR) subunits and expressed key nAChR subtypes in Xenopus oocytes including neuronal (alpha 4 beta 2, alpha 2 beta 2, alpha 3 beta 4, and alpha 7) and muscle (alpha 1 beta 1(b)epsilon delta) nAChR. Consistent with studies of mammalian nAChR, nicotine was relatively inactive on muscle-type receptors, having both low potency and efficacy. It had high efficacy but low potency for alpha 7 receptors, and the best potency and good efficacy for alpha 4 beta 2 receptors. Cytisine, a key lead compound for the development of smoking cessation agents, is a full agonist for both mammalian alpha 7 and alpha 3 beta 4 receptors, but a full agonist only for the fish alpha 7, with surprisingly low efficacy for alpha 3 beta 4. The efficacy of cytisine for alpha 4 beta 2 was somewhat greater than typically reported for mammalian alpha 4 beta 2. The ganglionic blocker mecamylamine was most potent for blocking alpha 3 beta 4 receptors, least potent for alpha 7, and roughly equipotent for the muscle receptors and the beta 2-containing nAChR. However, the block of beta 2-containing receptors was slowly reversible, consistent with effective targeting of these CNS-type receptors in vivo. Three prototypical alpha 7-selective agonists, choline, tropane, and 4OH-GTS-21, were tested, and these agents were observed to activate both fish alpha 7 and alpha 4 beta 2 nAChR. Our data therefore indicate that while some pharmacological tools used in zebrafish may function as expected, others will not. (C) 2012 Elsevier Inc. All rights reserved.

To address this issue, we performed a time course analysis in human embryonic fibroblast cells treated with DNA-damaging agents. DNA damage induced the phosphorylation of p53 at Ser 15 (p-p53) and the phosphorylation of ERK (p-ERK). Inhibition of p53 by a dominant negative mutant or in p53(-/-) fibroblast cells abolished ERK phosphorylation. ERK inhibitor prevented p53 phosphorylation, indicating that phosphorylations of p53 and p-ERK are interdependent each other. A time course analysis showed that ATM interacted with p-p53 and p-ERK in early time (0.5 h) and interaction between ATM-bound p-p53 and p-ERK or ATM-bound p-ERK and p-p53 occurred in late time (3 h) of DNA damage. These results indicate that ATM mediates interdependent activation of p53 and ERK through formation of a ternary complex between p-p53 and p-ERK in response to DNA damage to cause growth arrest.

These may be synchronous (more than one lesion at presentation) or metachronous (new tumor developing after the initial treatment). The incidence of multifocal OS has ranged from 1.5 to 5.4% in large series, with the synchronous type being rarer. Similarly, periosteal OS is another rare subtype of surface OS and constitutes less than 2% of all OS. An 11-year-old female was diagnosed with bilateral synchronous tibial periosteal OS, which were confirmed by CT-guided biopsies. After neoadjuvant chemotherapy, the patient underwent a staged wide local resection of the tumors. The defect was reconstructed with a proximal tibial replacement on the left side and autologous bone grafting on the right side. The patient did well after surgery and is free of disease at 5.5 years of follow-up. However, her brother also developed a right tibial periosteal osteosarcoma 4 years after her index surgery. Genetic analysis of blood sample from both patients showed a similar missense mutation in at least one allele of TP53 gene (exon 8). To the best of our knowledge, a case of bilateral 'synchronous' periosteal OS with a familial incidence has not been reported before.

In this study, we evaluate the role of the sickle cell trait (HbS) and ABO blood groups in the clinical manifestations of childhood malaria in Southwest Nigeria. The subjects comprised 3100 children (53% males, median age 39 months), including 1400 children with uncomplicated malaria, 1000 children with asymptomatic malaria and 700 with severe malaria. Haemoglobin (Hb) types were determined using electrophoresis and serum agglutination techniques were used to determine ABO blood groups. Blood group O was the commonest ABO blood group (47.7%) in the study population, the others were A (22.5%), B (25.2%) and AB (4.6%). The frequencies of the HbAS and HbAC were 14.4% and 5.8%, respectively. In regression models adjusting for age, gender, parasite density and blood group, HbAS was associated with a reduced risk of severe malaria OR=0.46 (CI95%: 0.273-0.773). Among severe malaria subjects, HbAS was associated with significantly lower parasite densities. The protective effect of blood group 0 was demonstrated with a decreased risk of severe malaria OR=0.743 (CI95%: 0.566-0.976) after adjusting for age, gender and parasite density and Hb genotype. Blood group B was associated with increased risk of severe malaria OR=1.638 (CI95%: 1.128-2.380) after adjusting for age, gender, packed cell volume, parasite density and Hb genotype. We have confirmed from this large study of Nigerian children the major protective effective of the sickle cell heterozygous state against both cerebral malaria and severe malarial anaemia. We also show that the B blood group is associated with an increased risk of severe malaria. In conclusion, the sickle cell haemoglobin type and ABO groups modulate the risk of severe malaria in Nigerian children. (C) 2012 Elsevier B.V. All rights reserved. C1 [Amodu, O. K.; Olaniyan, S.

Required concentration of the nanoparticles for the cell manipulation is as low as similar to 20 mu g Fe/mL. However, the relative ratio of the nanoparticles loaded NK-92MI cells infiltrated into the target tumor site is enhanced by 17-fold by applying magnetic field and their killing activity is still maintained as same as the NK-92MI cells without the nanoparticles. This approach allows us to open alternative clinical treatment with reduced toxicity of the nanoparticles and enhanced infiltration of immunology to the target site. (C) 2012 Elsevier Ltd.

Given the overlap in clinical signs in humans between malaria and, for example, pneumonia, the true cause of severe illness is sometimes difficult to establish. Traditional microbiological culture methods employed to detect systemic bactereamia are often time consuming and have modest sensitivity. Therefore, molecular methods have become increasingly used in the diagnosis of septicaemia. Here, we evaluated the usefulness of both broad-range 16S rRNA PCR, in conjunction with DNA sequencing and species-specific PCR targeting of Streptococcus pneumoniae and non-typhoidal Salmonella, to screen for bacterial co-infections in blood samples from children enrolled in a malaria pathogenesis study. PCR revealed no test-positive results for these pathogens and DNA sequencing of 16S rRNA amplicons identified the presence of bacterial genomic DNA (most probably from environmental bacterial sources) in a large proportion of samples. We demonstrate that the issue of potential mixed bacteraemic infection and/or background bacterial genomic DNA, which may relate to co-migration of PCR amplicons on agarose gels, can be overcome by using denaturing gradient gel electrophoresis (DGGE). PCR for Plasmodium spp. was also performed on genomic DNA from bloods from Gambian children with pneumonia, in order to estimate the prevalence of Plasmodium/pneumonia co-infections in the study population. While 12.2% of samples were test-positive, parasite density was very low and did not vary significantly between cases and controls. Published by Elsevier lid.

Chemoprevention has the potential to be an approach of utmost importance to reduce cancer burden at least among high-risk populations. Tamoxifen and raloxifene are both indicated for the prevention of breast cancer in women at high risk for the development of the disease, although raloxifene may have a more favorable adverse-effect profile, causing fewer uterine cancers and thromboembolic events. Aromatase inhibitors will most probably become an additional prevention treatment option in the near future, in view of the promising results observed in adjuvant trials and the interesting results of the very recently published first chemoprevention trial using an aromatase inhibitor.(2) Despite impressive results in most clinical trials performed to date, chemoprevention is still not widely used. Urgently needed are better molecular risk models to accurately identify high-risk subjects, new agents with a better risk/benefit ratio and validated biomarkers. (C) 2011 Elsevier Ltd.

Structural equation modeling was used to estimate the independent effects of parent psychopathology and family functioning problems by parent gender. Participants included 242 parents in treatment for substance abuse and/or dependence and 59 of their coparents (16.9% in treatment for substance-abuse/dependence) from middle income households (SES: M = 4.7; SD = 2.1). Ratings were obtained for 325 adolescents (48% female; 27.8% non-Caucasian) between the ages of 10 and 18 years (M = 13.5 years; SD = 2.5 years). Parent psychopathology, family functioning problems, and adolescent problems were assessed with parent and coparent ratings on the Symptom Checklist (SCL-90)/Brief Symptom Inventory (BSI), the Family Relationship Measure, and the Child Behavior Checklist, respectively. Results indicated that maternal psychopathology was directly related to adolescent internalizing problems and substance use, but maternal perceptions of family functioning problems failed to mediate relations between maternal psychopathology and adolescent problems. By contrast, paternal perceptions of family functioning problems uniquely mediated relations between paternal psychopathology and adolescent externalizing problems. Findings underscore the importance of examining how mothers and fathers may differentially impact adolescent problems in substance-abusing families.

Inflammatory mediators and cellular stressors regulate their activity. Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease of upper and lower motor neurons characterized by extensive neuroinflammation. Here we tested the hypothesis that disease-driven changes in ABC transporter expression and function occur in ALS. Given the multitude of ABC transporters with their widespread substrate recognition, we began by examining expression levels of several ABC transporters. We found a selective increase in only two transporters: P-glycoprotein (P-gp) and breast cancer resistance protein (BCRP) both at mRNA and protein levels, in the SOD1-G93A mouse model of ALS, specifically in disease-affected CNS regions. Detailed analysis revealed a similar disease-driven increase in P-gp and BCRP levels in spinal cord microvessels, indicating that their altered expression occurs at the blood spinal cord barrier. Transport activity of P-gp and BCRP increased with disease progression in spinal cord and cerebral cortex capillaries. Finally, P-gp and BCRP protein expression also increased in spinal cords of ALS patients. Preclinical drug trials in the mouse model of ALS have failed to decisively slow or arrest disease progression; pharmacoresistance imparted by ABC transporters is one possible explanation for these failures. Our observations have large implications for ALS therapeutics in humans and suggest that the obstacle provided by these transporters to drug treatments must be overcome to develop effective ALS pharmacotherapies.

The administration of craniospinal radiation after surgery offers the greatest chance for cure but causes severe neurocognitive damage. As a result, current practice does not offer parents the option of full-dose postoperative craniospinal radiation. Some may regard this approach as inappropriate medical paternalism, while others may consider it an example of responsible therapeutics. Evaluation of this dilemma reveals principles which can guide clinicians in determining which treatment options to present to their patients or surrogates, in the context of shared medical decision-making.

TI Initial testing of the investigational NEDD8-activating enzyme inhibitor MLN4924 by the pediatric preclinical testing program SO PEDIATRIC BLOOD & CANCER LA English DT Article DE developmental therapeutics; MLN4924; preclinical testing ID NF-KAPPA-B; CELL LYMPHOMA; CANCER MODELS; IN-VIVO; LEUKEMIA; ACTIVATION; EXPRESSION; REREPLICATION; ASTROCYTOMAS; APOPTOSIS AB Background MLN4924 is an investigational first-in-class small molecule inhibitor of NEDD8-activating enzyme (NAE). NAE is an essential component of the NEDD8 conjugation pathway, controlling the activity of a subset of ubiquitin-proteasome system (UPS) E3 ligases, multiprotein complexes that transfer ubiquitin molecules to substrate proteins. Procedures MLN4924 was tested against the PPTP in vitro panel using 96-hour exposure time at concentrations ranging from 1.0?nM to 10?mu M. It was tested in vivo at a dose of 100?mg/kg [66?mg/kg for the acute lymphoblastic leukemia (ALL) xenografts] administered orally twice daily?x?5 days. Treatment duration was 3 weeks. Results The median relative IC50 for MLN4924 against the PPTP cell lines was 143?nM, (range: 15678?nM) with that for the Ewing panel being significantly lower (31?nM). MLN4924 induced significant differences in EFS distribution compared to control in 20 of 34 (59%) evaluable solid tumor xenografts. MLN4924 induced intermediate activity (EFS T/C values >2) in 9 of the 33 evaluable xenografts (27%), including 4 of 4 glioblastoma xenografts, 2 of 3 Wilm's tumor xenografts, 2 of 5 rhabdomyosarcoma xenografts, and 1 of 4 neuroblastoma xenografts. For the ALL panel, 5 of 8 evaluable xenografts showed intermediate activity for the EFS T/C measure. MLN4924 did not induce objective responses in the PPTP solid tumor or ALL panels. Conclusions MLN4924 showed potent activity in vitro and in vivo showed tumor growth inhibitory activity against a subset of the PPTP solid tumor and ALL xenografts.

HCT can be curative, but is associated with significant toxicity. Procedure Between January 2001 and June 2009, 92 solid tumor patients (age 6 months to 27 years) underwent 94 autologous apheresis procedures at Children's National Medical Center. Out of that group, 71 patients, who underwent 162 autologous HCT, were analyzed for transplant outcomes. Multiple variable modeling was used to identify independent variables related to transplant toxicity outcome measures, such as bacteremia, intensive care admission, and death. Other outcome measures (time to pre-apheresis peripheral blood CD34+ count, product yield, and time to engraftment) were also analyzed. Independent variables included patient-specific variables (age, weight, tumor type, chemotherapy administered, and primary vs. relapsed disease) and harvest or transplant-related variables (total white blood cell and CD34+ cell counts prior to transplant, and quantity of total nucleated cells and CD34+ cells infused during transplant). Results Transplant toxicity was significantly greater in younger patients (P?=?0.001) and in neuroblastoma patients (P?=?0.003). The time to neutrophil engraftment, controlling for weight, age, and chemotherapy, was positively related to absolute CD34+ cells/kg infused (P?=?0.01). The time to CD34+ recovery pre-apheresis was affected by patient diagnosis (P?=?0.05). Conclusions Younger patients had increased transplant toxicity, with infants <1 year of age at highest risk for fever, bacteremia, admission to intensive care, and death. Infants would likely benefit from hospitalization after autologous HCT until neutrophil recovery. Pediatr Blood Cancer 2012;59:301305. (c) 2011 Wiley Periodicals, Inc.

TI Future directions of sickle cell disease research: The NIH perspective SO PEDIATRIC BLOOD & CANCER LA English DT Review DE global health; research; sickle cell disease AB Efforts to enhance therapy for children and adults with sickle cell disease (SCD) have proven more challenging than might have been predicted from the fact that an understanding of the underlying pathogenesis antedated that of many other diseases for which good treatments presently exist. The multi-organ injury that occurs with SCD certainly contributes to this clinical reality. Research over decades indicates that the primary defect in hemoglobin that results in polymerization of the protein under low oxygen conditions and resultant cellular deformity of the red blood cell initiates a complex downstream pathogenesis associated with vascular injury and organ ischemia. Deciphering this in a manner that informs successful therapies that improve all target organs continues to challenge hematologists. The National Heart, Lung and Blood Institute (NHLBI) is dedicated to support research across the basic science, translational and clinical spectrum to achieve these clinical outcomes. The following provides a brief summary of the research strategies which NHLBI is presently supporting and will support in the future to enhance care and ultimately, to effect cure of this hemoglobin disease that causes such suffering to those who inherit this monogenic disease.

Altered expression of miRNA is associated with cancer. Inflammation and nitric oxide modulates the development of lymphomas in p53 knockout mice and there exists a negative feedback loop between p53 and NOS2. Using a genetic strategy, we tested the hypothesis that inflammation-induced oxidative and nitrosative stress modulates miRNA expression in mouse model deficient in either p53 or NOS2. Mice treated with Corynebacterium parvum (C. parvum), to induce inflammation, clearly separated from controls by their miRNA profiles in wild-type, p53- and NOS2-knockout genetic backgrounds. C. parvum-induced inflammation significantly (p < 0.005) increased miR-21, miR-29b and miR-34a/b/c and decreased (p < 0.005) mir-29c and mir-181a/c expression in the spleen of C57BL mice. However, p53-knockout C57BL mice did not show a significant increase in the mir-34b/c or a decrease in mir-29c expression following C. parvum-induced inflammation. Expression of mir-21, mir-29b and mir-181a was independent of p53-status. NOS2-knockout C57BL mice showed a significant increase in miR-21 and miR-34a/b/c and decrease in miR-181a similar to the wild-type (WT) mice following C. parvum-induced inflammation. However, in contrast to the WT mice, miR-29b/c expression was not affected following C. parvum-induced inflammation in NOS2 knockout mice. N-acetyl cysteine, an anti-oxidant, reduced the expression of miR-21 and miR-29b in C. parvum-treated WT mice (p < 0.005) as compared with control C. parvum-treated mice. These data are consistent with the hypothesis that inflammation modulates miRNA expression in vivo and the alteration in specific miRNA under an inflammatory microenvironment, can be influenced by p53 (miR-34b/c) and NO (29b/c).

The new statistic can be also used for model selection in the non-nested models. The estimate of S Gamma(p), SC(p), is derived and shown to become SC epsilon(p) in the similar form of C-p in a single-equation model when the covariance matrix of sampled dependent variables is replaced by the error covariance matrix under the full model.

Major changes can be seen after minor stimuli, which make it a valuable target for analysis. Due to the diverse and sensitive nature of the metabolome, studies must be designed in a manner to maintain consistency, reduce variation between subjects, and optimize information recovery. Technological advancements in experimental design, mouse models and instrumentation have aided in this effort. Metabolomics has the ultimate potential to be valuable in a clinical setting where it could be used for early diagnosis of a disease and as a predictor of treatment response and survival. During drug treatment, the metabolic status of an individual could be monitored and used to indicate possible toxic effects. Metabolomics therefore has great potential for improving diagnosis, treatment and aftercare of disease. J. Cell. Physiol. 227: 29752981, 2012. Published 2011.

In such systems, one or more slow variables carry the fast variables through a sequence of bifurcations that mediate transitions between oscillations and steady states. A rigorous classification approach is to characterize the bifurcations found in the neighborhood of a singularity; a measure of the complexity of the bursting oscillation is then given by the smallest codimension of the singularities near which it occurs. Fold/homoclinic bursting, along with most other burst types of interest, has been shown to occur near a singularity of codimension three by examining bifurcations of a cubic Lienard system; hence, these types of bursting have at most codimension three. Modeling and biological considerations suggest that fold/homoclinic bursting should be found near fold/subHopf bursting, a more recently identified burst type whose codimension has not been determined yet. One would expect that fold/subHopf bursting has the same codimension as fold/homoclinic bursting, because models of these two burst types have very similar underlying bifurcation diagrams. However, no codimension-three singularity is known that supports fold/subHopf bursting, which indicates that it may have codimension four. We identify a three-dimensional slice in a partial unfolding of a doubly-degenerate Bodganov-Takens point, and show that this codimension-four singularity gives rise to almost all known types of bursting.

Several single-chain (scFv) antibodies, derived from an affinity-matured series of anti-hen egg white lysozyme (HEL) mouse IgGl, were constructed with either complete or individual replacement of tryptophan residues with 5-fluorotryptophan (W-5F). An array of biophysical techniques was used to gain insight into the impact of fluorine substitution on the overall protein structure and antigen binding. SPR measurements indicated that W-5F incorporation lowered binding affinity for the HEL antigen. The degree of analogue impact was residue-dependent, and the greatest decrease in affinity was observed when W-5F was substituted for residues near the binding interface. In contrast, corresponding crystal structures in complex with HEL were essentially indistinguishable from the unsubstituted antibody. F-19 NMR analysis showed severe overlap of signals in the free fluorinated protein that was resolved upon binding to antigen, suggesting very distinct chemical environments for each W-5F in the complex. Preliminary relaxation analysis suggested the presence of chemical exchange in the antibody antigen complex that could not be observed by X-ray crystallography. These data demonstrate that fluorine NMR can be an extremely useful tool for discerning structural changes in scFv antibody-antigen complexes with altered function that may not be discernible by other biophysical techniques.

Nevertheless, their tumor aggressiveness is distinct: PHEOs/PGLs metastasize rarely in VHL-, but frequently in SDHB-patients. To date, the molecular mechanisms causing the more aggressive phenotype in SDHB-PHEOs/PGLs remain largely unknown. Recently, however, an excellent model to study aggressive PHEOs (mouse tumor tissue (MTT) cells) has been developed from mouse PHEO cells (MPC). We employed this model for a proteomics based approach to identify changes characteristic for tumor aggressiveness, which we then explored in a homogeneous set of human SDHB- and VHL-PHEOs/PGLs. The increase of glucose transporter 1 in VHL, and of hexokinase 2 in VHL and SDHB, confirmed their glycolytic profile. In agreement with the cell model and in support of decoupling of glycolysis, the Krebs cycle and oxidative phosphorylation (OXPHOS), SDHB tumors showed increased lactate dehydrogenase levels. In SDHB-PGLs OXPHOS complex activity was increased at complex III and, as expected, decreased at complex II. Moreover, protein and mRNA expression of all tested OXPHOS-related genes were higher in SDHB-than in VHL-derived tumors. Although there was no direct evidence for increased reactive oxygen species production, elevated superoxide dismutase 2 expression may reflect elevated oxidative stress in SDHB-derived PHEOs/PGLs. For the first time, we show that despite dysfunction in complex II and evidence for a glycolytic phenotype, the Warburg effect does not seem to fully apply to SDHB-PHEOs/PGLs with respect to decreased OXPHOS. In addition, we present evidence for increased LDHA and SOD2 expression in SDHB-PHEOs/PGLs, proteins that have been proposed as promising therapeutic targets in other cancers. This study provides new insight into pathogenic mechanisms in aggressive human PHEOs/PGLs, which may lead to identifying new diagnostic and prognostic markers in the near future.

TI Identification of Rat Ventral Tegmental Area GABAergic Neurons SO PLOS ONE LA English DT Article ID CONDITIONED PLACE PREFERENCE; MIDBRAIN DOPAMINE NEURONS; IN-VIVO MICRODIALYSIS; MEDIATING OPIATE REWARD; GABA-CONTAINING NEURONS; NUCLEUS-ACCUMBENS; PREFRONTAL CORTEX; SUBSTANTIA-NIGRA; MORPHINE; RECEPTORS AB The canonical two neuron model of opioid reward posits that mu opioid receptor (MOR) activation produces reward by disinhibiting midbrain ventral tegmental area (VTA) dopamine neurons through inhibition of local GABAergic interneurons. Although indirect evidence supports the neural circuit postulated by this model, its validity has been called into question by growing evidence for VTA neuronal heterogeneity and the recent demonstration that MOR agonists inhibit GABAergic terminals in the VTA arising from extrinsic neurons. In addition, VTA MOR reward can be dopamine-independent. To directly test the assumption that MOR activation directly inhibits local GABAergic neurons, we investigated the properties of rat VTA GABA neurons directly identified with either immunocytochemistry for GABA or GAD65/67, or in situ hybridization for GAD65/67 mRNA. Utilizing co-labeling with an antibody for the neural marker NeuN and in situ hybridization against GAD65/67, we found that 23 +/- 3% of VTA neurons are GAD65/67(+). In contrast to the assumptions of the two neuron model, VTA GABAergic neurons are heterogeneous, both physiologically and pharmacologically. Importantly, only 7/13 confirmed VTA GABA neurons were inhibited by the MOR selective agonist DAMGO. Interestingly, all confirmed VTA GABA neurons were insensitive to the GABA(B) receptor agonist baclofen (0/6 inhibited), while all confirmed dopamine neurons were inhibited (19/19). The heterogeneity of opioid responses we found in VTA GABAergic neurons, and the fact that GABA terminals arising from neurons outside the VTA are inhibited by MOR agonists, make further studies essential to determine the local circuit mechanisms underlying VTA MOR reward.

Here we use several complementary bioinformatic approaches to identify ultraconserved cis-regulatory sequences potentially driving the expression of human ZIC2. We demonstrate that an 804 bp element in the 3' untranslated region (3'UTR) is highly conserved across the evolutionary history of vertebrates from fish to humans. Furthermore, we show that while genetic variation of this element is unexpectedly common among holoprosencephaly subjects (6/528 or >1%), it is not present in control individuals. Two of six proband-unique variants are de novo, supporting their pathogenic involvement in HPE outcomes. These findings support a general recommendation that the identification and analysis of key ultraconserved elements should be incorporated into the genetic risk assessment of holoprosencephaly cases.

TI Entry Tropism of BK and Merkel Cell Polyomaviruses in Cell Culture SO PLOS ONE LA English DT Article ID JC-VIRUS; PAPILLOMAVIRUS CAPSIDS; HEPARAN-SULFATE; GROWTH-FACTOR; IN-VITRO; CARCINOMA; RECEPTOR; DNA; LINE; IDENTIFICATION AB Merkel Cell Polyomavirus (MCV or MCPyV) was recently discovered in an aggressive form of skin cancer known as Merkel cell carcinoma (MCC). Integration of MCV DNA into the host genome likely contributes to the development of MCC in humans. MCV infection is common and many healthy people shed MCV virions from the surface of their skin. MCV DNA has also been detected in samples from a variety of other tissues. Although MCC tumors serve as a record that MCV can infect the Merkel cell lineage, the true tissue tropism and natural reservoirs of MCV infection in the host are not known. In an effort to gain insight into the tissue tropism of MCV, and to possibly identify cellular factors responsible for mediating infectious entry of the virus, the infection potential of human cells derived from a variety of tissues was evaluated. MCV gene transfer vectors (pseudoviruses) carrying reporter plasmid DNA encoding GFP or luciferase genes were used to transduce keratinocytes and melanocytes, as well as lines derived from MCC tumors and the NCI-60 panel of human tumor cell lines. MCV transduction was compared to transduction with pseudoviruses based on the better-studied human BK polyomavirus (BKV). The efficiency of MCV and BKV transduction of various cell types occasionally overlapped, but often differed greatly, and no clear tissue type preference emerged. Application of native MCV virions to a subset of highly transducible cell types suggested that the lines do not support robust replication of MCV, consistent with recent proposals that the MCV late phase may be governed by cellular differentiation in vivo. The availability of carefully curated gene expression data for the NCI-60 panel should make the MCV and BKV transduction data for these lines a useful reference for future studies aimed at elucidation of the infectious entry pathways of these viruses.

Despite extensive investigations into the effects of doxorubicin on the cardiovascular system, the molecular mechanisms of toxicity remain largely unknown. MicroRNAs are endogenously transcribed non-coding 22 nucleotide long RNAs that regulate gene expression by decreasing mRNA stability and translation and play key roles in cardiac physiology and pathologies. Increasing doses of doxorubicin, but not etoposide (a Topoisomerase II inhibitor devoid of cardiovascular toxicity), specifically induced the up-regulation of miR-208b, miR-216b, miR-215, miR-34c and miR-367 in rat hearts. Furthermore, the lowest dosing regime (1 mg/kg/week for 2 weeks) led to a detectable increase of miR-216b in the absence of histopathological findings or alteration of classical cardiac stress biomarkers. In silico microRNA target predictions suggested that a number of doxorubicin-responsive microRNAs may regulate mRNAs involved in cardiac tissue remodeling. In particular miR-34c was able to mediate the DOX-induced changes of Sipa1 mRNA (a mitogen-induced Rap/Ran GTPase activating protein) at the post-transcriptional level and in a seed sequence dependent manner. Our results show that integrated heart tissue microRNA and mRNA profiling can provide valuable early genomic biomarkers of drug-induced cardiac injury as well as novel mechanistic insight into the underlying molecular pathways.

Salit, Marc TI Synthetic Spike-in Standards Improve Run-Specific Systematic Error Analysis for DNA and RNA Sequencing SO PLOS ONE LA English DT Article ID CANCER GENOME; DISCOVERY; MUTATIONS; FRAMEWORK AB While the importance of random sequencing errors decreases at higher DNA or RNA sequencing depths, systematic sequencing errors (SSEs) dominate at high sequencing depths and can be difficult to distinguish from biological variants. These SSEs can cause base quality scores to underestimate the probability of error at certain genomic positions, resulting in false positive variant calls, particularly in mixtures such as samples with RNA editing, tumors, circulating tumor cells, bacteria, mitochondrial heteroplasmy, or pooled DNA. Most algorithms proposed for correction of SSEs require a data set used to calculate association of SSEs with various features in the reads and sequence context. This data set is typically either from a part of the data set being "recalibrated" (Genome Analysis ToolKit, or GATK) or from a separate data set with special characteristics (SysCall). Here, we combine the advantages of these approaches by adding synthetic RNA spike-in standards to human RNA, and use GATK to recalibrate base quality scores with reads mapped to the spike-in standards. Compared to conventional GATK recalibration that uses reads mapped to the genome, spike-ins improve the accuracy of Illumina base quality scores by a mean of 5 Phred-scaled quality score units, and by as much as 13 units at CpG sites. In addition, since the spike-in data used for recalibration are independent of the genome being sequenced, our method allows run-specific recalibration even for the many species without a comprehensive and accurate SNP database. We also use GATK with the spike-in standards to demonstrate that the Illumina RNA sequencing runs overestimate quality scores for AC, CC, GC, GG, and TC dinucleotides, while SOLiD has less dinucleotide SSEs but more SSEs for certain cycles.

In contrast to refolding of a denatured protein, cotranslational folding is complicated by the vectorial nature of nascent chains, the frequent ribosome pausing, and the cellular crowdedness. Here, we present a strategy called folding-associated cotranslational sequencing that enables monitoring of the folding competency of nascent chains during elongation at codon resolution. By using an engineered multidomain fusion protein, we demonstrate an efficient cotranslational folding immediately after the emergence of the full domain sequence. We also apply folding-associated cotranslational sequencing to track cotranslational folding of hemagglutinin in influenza A virus-infected cells. In contrast to sequential formation of distinct epitopes, the receptor binding domain of hemagglutinin follows a global folding route by displaying two epitopes simultaneously when the full sequence is available. Our results provide direct evidence of domain-wise global folding that occurs cotranslationally in mammalian cells. C1 [Han, Yan; Qian, Shu-Bing] Cornell Univ, Div Nutr Sci, Ithaca, NY 14853 USA.

TI Neuroepithelial body microenvironment is a niche for a distinct subset of Clara-like precursors in the developing airways SO PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA LA English DT Article ID CELL FATE; NEUROENDOCRINE DIFFERENTIATION; PROGENITOR CELLS; GENE-EXPRESSION; BINDING-PROTEIN; DEVELOPING LUNG; NOTCH; MOUSE; ACTIVATION; BODIES AB Clara cells of mammalian airways have multiple functions and are morphologically heterogeneous. Although Notch signaling is essential for the development of these cells, it is unclear how Notch influences Clara cell specification and if diversity is established among Clara cell precursors. Here we identify expression of the secretoglobin Scgb3a2 and Notch activation as early events in a program of secretory cell fate determination in developing murine airways. We show that Scgb3a2 expression in vivo is Notch-dependent at early stages and ectopically induced by constitutive Notch1 activation, and also that in vitro Notch signaling together with the pan-airway transcription factor Ttf1 (Nkx2.1) synergistically regulate secretoglobin gene transcription. Furthermore, we identified a subpopulation of secretory precursors juxtaposed to presumptive neuroepithelial bodies (NEBs), distinguished by their strong Scgb3a2 and uroplakin 3a (Upk3a) signals and reduced Ccsp (Scgb1a1) expression. Genetic ablation of Ascl1 prevented NEB formation and selectively interfered with the formation of this subpopulation of cells. Lineage labeling of Upk3a-expressing cells during development showed that these cells remain largely uncommitted during embryonic development and contribute to Clara and ciliated cells in the adult lung. Together, our findings suggest a role for Notch in the induction of a Clara cell-specific program of gene expression, and reveals that the NEB microenvironment in the developing airways is a niche for a distinct subset of Clara-like precursors.

TI Melanoregulin regulates a shedding mechanism that drives melanosome transfer from melanocytes to keratinocytes SO PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA LA English DT Article ID DILUTE MELANOCYTES; MELANIN TRANSFER; ESCRT MACHINERY; COAT COLOR; MYOSIN-V; TRANSPORT; ABSCISSION; SUPPRESSOR; DYNAMICS; COMPLEX AB Mammalian pigmentation is driven by the intercellular transfer of pigment-containing melanosomes from the tips of melanocyte dendrites to surrounding keratinocytes. Tip accumulation of melanosomes requires myosin Va, because melanosomes concentrate in the center of melanocytes from myosin Va-null (dilute) mice. This distribution defect results in inefficient melanosome transfer and a dilution of coat color. Dilute mice that simultaneously lack melanoregulin, the product of the dilute suppressor locus, exhibit a nearly complete restoration of coat color, but, surprisingly, melanosomes remain concentrated in the center of their melanocytes. Here we show that dilute/dsu melanocytes, but not dilute melanocytes, readily transfer the melanosomes concentrated in their center to surrounding keratinocytes in situ. Using time-lapse imaging of WT melanocyte/keratinocyte cocultures in which the plasma membranes of the two cells are marked with different colors, we define an intercellular melanosome transfer pathway that involves the shedding by the melanocyte of melanosome-rich packages, which subsequently are phagocytosed by the keratinocyte. Shedding, which occurs primarily at dendritic tips but also from more central regions, involves adhesion to the keratinocyte, thinning behind the forming package, and apparent self-abscission. Finally, we show that shedding from the cell center is sixfold more frequent in cultured dilute/dsu melanocytes than in dilute melanocytes, consistent with the in situ data. Together, these results explain how dsu restores the coat color of dilute mice without restoring intracellular melanosome distribution, indicate that melanoregulin is a negative regulator of melanosome transfer, and provide insight into the mechanism of intercellular melanosome transfer.

TI The Scaffolding Protein Synapse-Associated Protein 97 Is Required for Enhanced Signaling Through Isotype-Switched IgG Memory B Cell Receptors SO SCIENCE SIGNALING LA English DT Article ID ANTIGEN RECEPTOR; IMMUNOLOGICAL SYNAPSE; PDZ DOMAINS; T-CELLS; ACTIVATION; INITIATION; TAIL; ORGANIZATION; REGULATOR; COMPLEXES AB After their first encounter with a foreign antigen, nave B cells that have immunoglobulin M (IgM) B cell receptors (BCRs) trigger the primary antibody response and the generation of memory B cells with IgG BCRs. When these memory B cells reencounter the same antigen, the cell surface IgG BCRs stimulate their rapid differentiation into plasma cells that release large amounts of IgG antibodies. We showed that the conserved cytoplasmic tail of the IgG BCR, which contains a putative PDZ (postsynaptic density 95/disc large/zona occludens 1)-binding motif, associated with synapse-associated protein 97 (SAP97), a PDZ domain-containing scaffolding molecule that is involved in controlling receptor density and signal strength at neuronal synapses. SAP97 accumulated and bound to IgG BCRs in the immunological synapses that formed in response to B cell engagement with antigen. Knocking down SAP97 in IgG(+) B cells or mutating the putative PDZ-binding motif in the BCR tail impaired formation of the immunological synapse, initiation of IgG BCR signaling, and downstream activation of the mitogen-activated protein kinase p38. Thus, heightened B cell memory responses are encoded, in part, by a mechanism that involves SAP97 serving as a scaffolding protein in the IgG BCR immunological synapse.

TI Human papillomavirus incidence and clearance among HIV-positive and HIV-negative men in sub-Saharan Africa SO AIDS LA English DT Article DE HIV; human papillomavirus; male circumcision; Uganda ID SIMPLEX-VIRUS TYPE-2; RISK HUMAN-PAPILLOMAVIRUS; MALE CIRCUMCISION; RANDOMIZED-TRIAL; FEMALE PARTNERS; CERVICAL-CANCER; INFECTED MEN; NATURAL-HISTORY; HPV INFECTIONS; GENITAL WARTS AB Objectives: High-risk human papillomavirus (HR-HPV) infection is the most common sexually transmitted infection. Penile and cervical cancer rates are highest in sub-Saharan Africa. However, little is known about the impact of HIV infection on HR-HPV acquisition and clearance among heterosexual men. Design: HR-HPV incidence and clearance were evaluated in 999 men (776 HIV-negative and 223 HIV-positive) aged 15-49 years who participated in male circumcision trials in Rakai, Uganda. Methods: Penile swabs were tested for HR-HPV by Roche HPV Linear Array. A Poisson multivariable model was used to estimate adjusted incidence rate ratios (adjIRRs) and clearance risk ratios (adjRRs). Results: HR-HPV incidence was 66.5/100 person-years in HIV-positive men and 32.9/100 person-years among HIV-negative men [IRR = 2.02, 95% confidence interval (CI) 1.67-2.44]. Incidence was higher in the unmarried men (adjIRR = 1.73, 95% CI 1.19-2.52), and decreased with age (adjIRR for men >35 years = 0.64, 95% CI 0.43-0.94) and male circumcision (adjIRR = 0.70, 95% CI 0.55-0.89). HR-HPV clearance was 114.7/100 person-years for HIV-positive men and 170.2/100 person-years for HIV-negative men (risk ratio = 0.67, 95% CI 0.59-0.77). HR-HPV clearance in HIV-negative men increased with circumcision (adjRR = 1.48, 95% CI 1.26-1.74), HSV-2 infection (adjRR = 1.20, 95% CI 1.01-1.44), and symptoms of urethral discharge (adjRR = 1.35, 95% CI 1.06-1.73). Clearance of HR-HPV was significantly lower for unmarried men (adjRR 0.76, 95% CI 0.59-0.98). Conclusion: HR-HPV is common among heterosexual Ugandan men, particularly the HIV-infected. HIV infection increases HR-HPV acquisition and reduces HR-HPV clearance. Promotion of male circumcision and additional prevention measures, such as HPV vaccination, is critical in sub-Saharan Africa.

However, it remains unclear whether recency of drug use impacts this impairment. Therefore, in this event-related potential study, recency of cocaine use was objectively determined by measuring cocaine in urine on study day. Thirty-five individuals with current cocaine use disorder [CUD: 21 testing positive (CUD+) and 14 testing negative (CUD) for cocaine in urine] and 23 healthy controls completed a sustained attention task with graded monetary incentives (0(sic), 1(sic) and 45(sic). Unlike in controls, in both CUD subgroups P300 amplitude was not modulated by the varying amounts of money and the CUD- showed the most severe impairment as documented by the lowest P300 amplitudes and task accuracy. Moreover, while recency of drug use was associated with better accuracy and higher P300 amplitudes, chronic drug use was associated with lower sensitivity to money. These results extend our previous findings of decreased sustained sensitivity to monetary reward in CUD+ to recently abstaining individuals, where level of impairment was most severe. Taken together, these results support the self-medication hypothesis, where CUD may be self-administering cocaine to avoid or compensate for underlying cognitive and emotional difficulties albeit with a long-term detrimental effect on sensitivity to non-drug reward.

Here we describe an in vivo mouse model that recapitulates the most frequent rearrangement in prostate cancer, the fusion of the promoter region of TMPRSS2 with the coding region of the transcription factor, ERG. A recombinant bacterial artificial chromosome including an extended TMPRSS2 promoter driving genomic ERG was constructed and used for transgenesis in mice. TMPRSS2-ERG expression was evaluated in tissue sections and FACS-fractionated prostate cell populations. In addition to the anticipated expression in luminal cells, TMPRSS2-ERG was similarly expressed in the Sca-1(hi)/EpCAM(+) basal/progenitor fraction, where expanded numbers of clonogenic self-renewing progenitors were found, as assayed by in vitro sphere formation. These clonogenic cells increased intrinsic self renewal in subsequent generations. In addition, ERG dependent self-renewal and invasion in vitro was demonstrated in prostate cell lines derived from the model. Clinical studies have suggested that the TMPRSS2-ERG translocation occurs early in prostate cancer development. In the model described here, the presence of the TMPRSS2-ERG fusion alone was not transforming but synergized with heterozygous Pten deletion to promote PIN. Taken together, these data suggest that one function of TMPRSS2-ERG is the expansion of self-renewing cells, which may serve as targets for subsequent mutations. Primary prostate epithelial cells demonstrated increased post transcriptional turnover of ERG compared to the TMPRSS2-ERG positive VCaP cell line, originally isolated from a prostate cancer metastasis. Finally, we determined that TMPRSS2-ERG expression occurred in both castration-sensitive and resistant prostate epithelial subpopulations, suggesting the existence of androgen-independent mechanisms of TMPRSS2 expression in prostate epithelium.

Materials and Methods: Seventy patients with proven HCM underwent cardiac MRI. Absolute and relative resting MBF were calculated from cardiac perfusion MRI by using the Fermi function model. The relationship between relative MBF and LV wall thickness, T2-signal abnormalities (T2 dark and T2 bright signal), LGE, age and LV outflow gradient as determined by echocardiography was determined using simple and multiple linear regression analysis. Categories of reduced and elevated perfusion in relation to non- or mildly affected reference segments were defined, and T2-signal characteristics and extent as well as pattern of LGE were examined. Statistical testing included linear and logistic regression analysis, unpaired t-test, odds ratios, and Fisher's exact test. Results: 804 segments in 70 patients were included in the analysis. In a simple linear regression model LV wall thickness (p<0.001), extent of LGE (p<0.001), presence of edema, defined as focal T2 bright signal (p<0.001), T2 dark signal (p<0.001) and age (p = 0.032) correlated inversely with relative resting MBF. The LV outflow gradient did not show any effect on resting perfusion (p = 0.901). Multiple linear regression analysis revealed that LGE (p<0.001), edema (p = 0.026) and T2 dark signal (p = 0.019) were independent predictors of relative resting MBF. Segments with reduced resting perfusion demonstrated different LGE patterns compared to segments with elevated resting perfusion. Conclusion: In HCM resting MBF is significantly reduced depending on LV wall thickness, extent of LGE, focal T2 signal abnormalities and age. Furthermore, different patterns of perfusion in HCM patients have been defined, which may represent different stages of disease.

TisB and its analogs form multi-state ion-conductive pores in planar lipid bilayers with all states displaying similar anionic selectivity. TisB analogs differing by +/- 1 elementary charges show corresponding changes in selectivity. Probing TisB pores with poly-(ethylene glycol)s reveals only restricted partitioning even for the smallest polymers, suggesting that the pores are characterized by a relatively small diameter. These findings allow us to suggest that TisB forms clusters of narrow pores that are essential for its mechanism of action.

Hummer, Gerhard TI Entropy of single-file water in (6,6) carbon nanotubes SO JOURNAL OF CHEMICAL PHYSICS LA English DT Article ID MOLECULAR-DYNAMICS; ELECTRIC-FIELD; LIQUID WATER; TEMPERATURE; TRANSITION; ADSORPTION; SIMULATION; TRANSPORT; PROTEINS; CHANNEL AB We used molecular dynamics simulations to investigate the thermodynamics of filling of a (6,6) open carbon nanotube (diameter D = 0.806 nm) solvated in TIP3P water over a temperature range from 280 K to 320 K at atmospheric pressure. In simulations of tubes with slightly weakened carbon-water attractive interactions, we observed multiple filling and emptying events. From the water occupancy statistics, we directly obtained the free energy of filling, and from its temperature dependence the entropy of filling. We found a negative entropy of about -1.3 k(B) per molecule for filling the nanotube with a hydrogen-bonded single-file chain of water molecules. The entropy of filling is nearly independent of the strength of the attractive carbon-water interactions over the range studied. In contrast, the energy of transfer depends strongly on the carbon-water attraction strength. These results are in good agreement with entropies of about -0.5 k(B) per water molecule obtained from grand-canonical Monte Carlo calculations of water in quasi-infinite tubes in vacuum under periodic boundary conditions. Overall, for realistic carbon-water interactions we expect that at ambient conditions filling of a (6,6) carbon nanotube open to a water reservoir is driven by a favorable decrease in energy, and opposed by a small loss of water entropy.

TI Replica exchanging self-guided Langevin dynamics for efficient and accurate conformational sampling SO JOURNAL OF CHEMICAL PHYSICS LA English DT Article ID ACCELERATED MOLECULAR-DYNAMICS; PROTEIN-FOLDING SIMULATION; UNRES FORCE-FIELD; MONTE-CARLO; BIOMOLECULAR SYSTEMS; STRUCTURE PREDICTION; EXPLICIT-SOLVENT; IMPLICIT SOLVENT; MODEL; PEPTIDES AB This work presents a replica exchanging self-guided Langevin dynamics (RXSGLD) simulation method for efficient conformational searching and sampling. Unlike temperature-based replica exchanging simulations, which use high temperatures to accelerate conformational motion, this method uses self-guided Langevin dynamics (SGLD) to enhance conformational searching without the need to elevate temperatures. A RXSGLD simulation includes a series of SGLD simulations, with simulation conditions differing in the guiding effect and/or temperature. These simulation conditions are called stages and the base stage is one with no guiding effect. Replicas of a simulation system are simulated at the stages and are exchanged according to the replica exchanging probability derived from the SGLD partition function. Because SGLD causes less perturbation on conformational distribution than high temperatures, exchanges between SGLD stages have much higher probabilities than those between different temperatures. Therefore, RXSGLD simulations have higher conformational searching ability than temperature based replica exchange simulations. Through three example systems, we demonstrate that RXSGLD can generate target canonical ensemble distribution at the base stage and achieve accelerated conformational searching. Especially for large systems, RXSGLD has remarkable advantages in terms of replica exchange efficiency, conformational searching ability, and system size extensiveness.

Methods: Participants of this prospective study were 21 to 45 year-old premenopausal women with MDD (n = 92) and healthy controls (n = 44). We measured BMD at the anteroposterior lumbar spine, femoral neck, total hip, mid-distal radius, trochanter, and Ward's triangle, as well as serum intact parathyroid hormone (iPTH), ionized calcium, plasma adrenocorticotropic hormone (ACTH), serum cortisol, and 24-hour urinary-free cortisol levels at 0, 6, 12, 24, and 36 months. 25-hydroxyvitamin D was measured at baseline. Results: At baseline, BMD tended to be lower in women with MDD compared to controls and BMD remained stable over time in both groups. At baseline, 6, 12, and 24 months intact PTH levels were significantly higher in women with MDD vs. controls. At baseline, ionized calcium and 25-hydroxyvitamin D levels were significantly lower in women with MDD compared to controls. At baseline and 12 months, bone-specific alkaline phosphatase, a marker of bone formation, was significantly higher in women with MDD vs. controls. Plasma ACTH was also higher in women with MDD at baseline and 6 months. Serum osteocalcin, urinary N-telopeptide, serum cortisol, and urinary free cortisol levels were not different between the two groups throughout the study. Conclusion: Women with MDD tended to have lower BMD than controls over time. Larger and longer studies are necessary to extend these observations with the possibility of prophylactic therapy for osteoporosis.

Methods: A total of 375 incident NPC cases and 327 controls matched to the cases on sex, age, and residence were recruited between July 1991 and December 1994. A structured questionnaire inquiring complete dietary history, socio-demographic characteristics, and other potential confounding factors was used in the personal interview. Unconditional logistic regression analysis was used to estimate multivariate-adjusted odds ratio (ORadj) with 95% confidence interval (CI) after accounting for known risk factors. Results: Fresh fish (ORadj, 0.56; 95% CI, 0.38-0.83 for the highest vs. lowest tertile of intake), green tea (ORadj, 0.61; 95% CI, 0.40-0.91 for drinking >= 1 times/week vs. never) and coffee (ORadj, 0.56; 95% CI, 0.37-0.85 for drinking 0.5 times/week vs. never) were inversely associated with the NPC risk. No association with NPC risk was observed for the intake of meats, salted fish, fresh vegetables, fruits and milk. Intake of vitamin A from plant sources was associated with a decreased NPC risk (ORadj, 0.62; 95% CI, 0.41-0.94 for the highest vs. lowest tertile). Conclusion: The study findings suggest that certain adult dietary patterns might protect against the development of NPC.

TI Therapeutic Inhibition of Pro-Inflammatory Signaling and Toxicity to Staphylococcal Enterotoxin B by a Synthetic Dimeric BB-Loop Mimetic of MyD88 SO PLOS ONE LA English DT Article ID MHC CLASS-II; INNATE IMMUNE-RESPONSES; CRYSTAL-STRUCTURE; HUMAN-DISEASE; MOLECULES; CYTOKINE; SHOCK; ENDOTOXIN; DOMAIN; MICE AB Staphylococcal enterotoxin B (SEB) exposure triggers an exaggerated pro-inflammatory cytokine response that often leads to toxic shock syndrome (TSS) associated with organ failure and death. MyD88 mediates pro-inflammatory cytokine signaling induced by SEB exposure and MyD88(-/-) mice are resistant to SEB intoxication, suggesting that MyD88 may be a potential target for therapeutic intervention. We targeted the BB loop region of the Toll/IL-1 receptor (TIR) domain of MyD88 to develop small-molecule therapeutics. Here, we report that a synthetic compound (EM-163), mimic to dimeric form of BB-loop of MyD88 attenuated tumor necrosis factor (TNF)-alpha, interferon (IFN)-gamma, interleukin (IL)-1 beta, IL-2 and IL-6 production in human primary cells, whether administered pre- or post-SEB exposure. Results from a direct binding assay, and from MyD88 co-transfection/co-immunoprecipitation experiments, suggest that EM-163 inhibits TIR-TIR domain interaction. Additional results indicate that EM-163 prevents MyD88 from mediating downstream signaling. In an NF-kBdriven reporter assay of lipopolysaccharide-stimulated MyD88 signaling, EM-163 demonstrated a dose-dependent inhibition of reporter activity as well as TNF-alpha and IL-1 beta production. Importantly, administration of EM-163 pre- or post exposure to a lethal dose of SEB abrogated pro-inflammatory cytokine responses and protected mice from toxic shock-induced death. Taken together, our results suggest that EM-163 exhibits a potential for therapeutic use against SEB intoxication.

TI Viral Reverse Transcriptases Show Selective High Affinity Binding to DNA-DNA Primer-Templates that Resemble the Polypurine Tract SO PLOS ONE LA English DT Article ID HUMAN-IMMUNODEFICIENCY-VIRUS; RNASE-H CLEAVAGE; IN-VITRO; NUCLEOCAPSID PROTEIN; SARCOMA-VIRUS; PLUS STRANDS; MUTATIONS; INITIATION; SEQUENCES; HYBRIDS AB Previous results using a SELEX (Systematic Evolution of Ligands by Exponential Enrichment)-based approach that selected DNA primer-template duplexes binding with high affinity to HIV reverse transcriptase (RT) showed that primers mimicking the 3' end, and in particular the six nt terminal G tract, of the RNA polypurine tract (PPT; HIV PPT: 5'-AAAAGAAAAGGGGGG-3') were preferentially selected. In this report, two viral (Moloney murine leukemia virus (MuLV) and avian myeloblastosis virus (AMV)) and one retrotransposon (Ty3) RTs were used for selection. Like HIV RT, both viral RTs selected duplexes with primer strands mimicking the G tract at the PPT 3' end (AMV PPT: 5'-AGGGAGGGGGA-3'; MuLV PPT: 5'-AGAAAAAGGGGGG-3'). In contrast, Ty3, whose PPT lacks a G tract (5'-GAGAGAGAGGAA-3') showed no selective binding to any duplex sequences. Experiments were also conducted with DNA duplexes (termed DNA PPTs) mimicking the RNA PPT-DNA duplex of each virus and a control duplex with a random DNA sequence. Retroviral RTs bound with high affinity to all viral DNA PPT constructs, with HIV and MuLV RTs showing comparable binding to the counterpart DNA PPT duplexes and reduced affinity to the AMV DNA PPT. AMV RT showed similar behavior with a modest preference for its own DNA PPT. Ty3 RT showed no preferential binding for its own or any other DNA PPT and viral RTs bound the Ty3 DNA PPT with relatively low affinity. In contrast, binding affinity of HIV RT to duplexes containing the HIV RNA PPT was less dependent on the G tract, which is known to be pivotal for efficient extension. We hypothesize that the G tract on the RNA PPT helps shift the binding orientation of RT to the 3' end of the PPT where extension can occur.

TI A Smell That Causes Seizure SO PLOS ONE LA English DT Article ID ANTERIOR PIRIFORM CORTEX; OLFACTORY SENSORY MAP; ODORANT RECEPTORS; TOPOGRAPHIC MAP; EVOKED ACTIVITY; C-FOS; BULB; REPRESENTATIONS; INHIBITION; SYSTEM AB In mammals, odorants are detected by a large family of receptors that are each expressed in just a small subset of olfactory sensory neurons (OSNs). Here we describe a strain of transgenic mice engineered to express an octanal receptor in almost all OSNs. Remarkably, octanal triggered a striking and involuntary phenotype in these animals, with passive exposure regularly inducing seizures. Octanal exposure invariably resulted in widespread activation of OSNs but interestingly seizures only occurred in 30-40% of trials. We hypothesized that this reflects the need for the olfactory system to filter strong but slowly-changing backgrounds from salient signals. Therefore we used an olfactometer to control octanal delivery and demonstrated suppression of responses whenever this odorant is delivered slowly. By contrast, rapid exposure of the mice to octanal induced seizure in every trial. Our results expose new details of olfactory processing and provide a robust and non-invasive platform for studying epilepsy. C1 [Nguyen, Minh Q.; Ryba, Nicholas J.

Conditional mutants that underexpress essential genes have been used to identify compounds with known mechanism of action by target-based whole-cell screening (TB-WCS). Here, the feasibility of TB-WCS in Mtb was assessed by generating mutants that conditionally express pantothenate synthetase (panC), diaminopimelate decarboxylase (lysA), and isocitrate lyase (icl1). The essentiality of panC and lysA, and conditional essentiality of icl1 for growth on fatty acids, was confirmed. Depletion of PanC and Icl1 rendered mutants hypersensitive to target-specific inhibitors. Stable reporter strains were generated for use in high-throughput screening, and their utility was demonstrated by identifying compounds that display greater potency against a PanC-depleted strain. These findings illustrate the power of TB-WCS as a tool for tuberculosis drug discovery.

Using a mouse model, we show a role for the indigenous microbiota and mast cells (MCs) in skin disease associated with mutant NIrp3 protein. Unlike normal cells, MCs expressing mutant NIrp3 produced IL-1 beta in response to lipopolysaccharide or tumor necrosis factor-alpha (TNF-alpha). In neonatal mice, the microbiota induced TNF-alpha and IL-1 beta and promoted skin disease. MC deficiency greatly reduced disease in NIrp3 mutant mice, and reconstitution of MC-deficient mice with mutant MCs restored skin disease, which required the expression of IL-1 beta in MCs. Surprisingly, neutralization of TNF-alpha abrogated IL-1 beta production and skin disease in neonatal NIrp3 mutant mice, but not in affected adult mice. Thus, the microbiota and MCs initiate cellular events leading to dysregulated IL-1 beta production and skin inflammation in neonatal mice with the CAPS-associated NIrp3 mutation.

Although studies have focused on the genetic differences between the resistant and susceptible chicken, less is known about the role of epigenetic factors in MD. In this study, genome-wide histone modifications in the non-MHC-associated resistant and susceptible chicken lines were examined. We found that tri-methylation at histone H3 Lys4 (H3K4me3) enrichment is positively correlated with the expression of protein coding genes as well as microRNA (miRNA) genes, whereas tri-methylation at histone H3 Lys27 (H3K27me3) exhibits a negative correlation. By identifying line-specific histone modifications in MDV infection, we found unique H3K4me3 islands in the resistant chicken activated genes, which are related to immune response and cell adhesion. Interestingly, we also found some miRNAs from unique H3K27me3 patterns in the susceptible chickens that targeted genes involved in 5-hydroxytryptamine (5-HT)-receptor and adrenergic receptor pathways. In conclusion, dynamic line-specific histone modifications in response to MDV infection suggested that intrinsic epigenetic mechanisms may play a role in MD-resistance and -susceptibility.

Reinhold, William Pommier, Yves TI Concordance of Gene Expression and Functional Correlation Patterns across the NCl-60 Cell Lines and the Cancer Genome Atlas Glioblastoma Samples SO PLOS ONE LA English DT Article ID TOOL AB Background: The NCl-60 is a panel of 60 diverse human cancer cell lines used by the U. S. National Cancer Institute to screen compounds for anticancer activity. We recently clustered genes based on correlation of expression profiles across the NCl-60. Many of the resulting clusters were characterized by cancer-associated biological functions. The set of curated glioblastoma (GBM) gene expression data from the Cancer Genome Atlas (TCGA) initiative has recently become available. Thus, we are now able to determine which of the processes are robustly shared by both the immortalized cell lines and clinical cancers. Results: Our central observation is that some sets of highly correlated genes in the NCl-60 expression data are also highly correlated in the GBM expression data. Furthermore, a "double fishing'' strategy identified many sets of genes that show Pearson correlation >= 0.60 in both the NCl-60 and the GBM data sets relative to a given "bait'' gene. The number of such gene sets far exceeds the number expected by chance. Conclusion: Many of the gene-gene correlations found in the NCl-60 do not reflect just the conditions of cell lines in culture; rather, they reflect processes and gene networks that also function in vivo. A number of gene network correlations co-occur in the NCl-60 and GBM data sets, but there are others that occur only in NCl-60 or only in GBM. In sum, this analysis provides an additional perspective on both the utility and the limitations of the NCl-60 in furthering our understanding of cancers in vivo.

Cancer risk increases with age, but associations of ESRD with specific malignancies are incompletely studied for older individuals. Methods: We conducted a population-based case-control study (1,029,695 cancer and 99,610 controls) among the U. S. elderly using SEER-Medicare linked data. We defined ESRD as presence of dialysis claims in the 3 months prior to selection. Results: Although ESRD was not associated with excess cancer risk overall (odds ratio 1.02; 95%CI 0.91 1.14), risk was specifically increased for cancers of the stomach (1.45; 1.16-1.81), small intestine (1.92; 1.27-2.92), colon (1.17; 1.00-1.36), liver (1.53; 1.16-2.01), biliary tract (1.78; 1.20-2.65), lung (1.17; 1.02-1.34), cervix (2.12; 1.39-3.23), kidney (2.42; 2.01-2.92), and for multiple myeloma (1.77; 1.40-2.24) and chronic myeloid leukemia (1.74; 1.08-2.80). The association between liver cancer and ESRD was attenuated upon adjustment for hepatitis B and C infection or diabetes mellitus. Multiple myeloma risk was highest with short ESRD duration (p < 0.0001), possibly reflecting reverse causality, while kidney cancer risk showed a borderline rise over time (p = 0.08). Conclusions: Among elderly individuals with ESRD, the excess risks for some cancers may reflect immune dysfunction or a high prevalence of other risk factors, such as viral infections or diabetes mellitus. Our results underscore the need for studying biological pathways of carcinogenesis in ESRD.

TI Sonic Hedgehog Maintains Cellular and Neurochemical Homeostasis in the Adult Nigrostriatal Circuit SO NEURON LA English DT Article ID PEDUNCULOPONTINE TEGMENTAL NUCLEUS; CHOLINERGIC INTERNEURONS; DOPAMINERGIC-NEURONS; NEUROTROPHIC FACTOR; PARKINSONS-DISEASE; GDNF; RAT; PROTEIN; PROLIFERATION; INHIBITION AB Non cell-autonomous processes are thought to play critical roles in the cellular maintenance of the healthy and diseased brain but mechanistic details remain unclear. We report that the interruption of a non cell-autonomous mode of sonic hedgehog (Shh) signaling originating from dopaminergic neurons causes progressive, adult-onset degeneration of dopaminergic, cholinergic, and fast spiking GABAergic neurons of the mesostriatal circuit, imbalance of cholinergic and dopaminergic neurotransmission, and motor deficits reminiscent of Parkinson's disease. Variable Shh signaling results in graded inhibition of muscarinic autoreceptor- and glial cell line-derived neurotrophic factor (GDNF)expression in the striatum. Reciprocally, graded signals that emanate from striatal cholinergic neurons and engage the canonical GDNF receptor Ret inhibit Shh expression in dopaminergic neurons. Thus, we discovered a mechanism for neuronal subtype specific and reciprocal communication that is essential for neurochemical and structural homeostasis in the nigrostriatal circuit. These results provide integrative insights into non cell-autonomous processes likely at play in neurodegenerative conditions such as Parkinson's disease.

TI Common variation at 6p21.31 (BAK1) influences the risk of chronic lymphocytic leukemia SO BLOOD LA English DT Article ID GENOME-WIDE ASSOCIATION; CANCER; APOPTOSIS; PREVENTION AB We performed a meta-analysis of 3 genome-wide association studies to identify additional common variants influencing chronic lymphocytic leukemia (CLL) risk. The discovery phase was composed of genome-wide association study data from 1121 cases and 3745 controls. Replication analysis was performed in 861 cases and 2033 controls. We identified a novel CLL risk locus at 6p21.33 (rs210142; intronic to the BAK1 gene, BCL2 antagonist killer 1; P = 9.47 x 10(-16)). A strong relationship between risk genotype and reduced BAK1 expression was shown in lymphoblastoid cell lines. This finding provides additional support for polygenic inheritance to CLL and provides further insight into the biologic basis of disease development.

In all cases, terminology and basic results from the theory of Lie groups are used to describe rigid-body motions in a coordinate free way, and when necessary, coordinates are introduced in a way in which simple equations result We consider double-helical DNAs and RNAs which, in their unstressed referential state, have backbones that are either straight, slightly precurved, or bent by the action of a protein or other bound molecule. At the coarsest level, we consider worm-like chains with anisotropic bending stiffness. Then, we show how bi-rod models converge to this for sufficiently long filament lengths. At a finer level, we examine elastic networks of rigid bases and show how these relate to the coarser models. Finally, we show how results from molecular dynamics simulation at full atomic resolution (which is the finest scale considered here) and AFM experimental measurements (which is at the coarsest scale) relate to these models.

Pathways are assessed by the amount of reactive flux they carry and by their orientation relative to the committor function. By examining the. effects of transforming between different collective coordinates that span the same underlying space, we unmask artificial coordinate dependences in strings optimized to follow the free energy gradient In contrast, strings optimized to follow the drift vector produce reaction pathways that are significantly less sensitive to reparameterizations of the collective coordinates. The differences in these paths arise because the drift vector depends on both the free energy gradient and the diffusion tensor of the coarse collective variables. Anisotropy and position dependence of diffusion tensors arise commonly in spaces of coarse variables, whose generally slow dynamics are obtained by nonlinear projections of the strongly coupled atomic motions. We show here that transition paths constructed to account for, dynamics by following the drift vector will (to a close approximation) carry the maximum reactive flux both in systems with isotropic position dependent diffusion and in systems with constant but anisotropic diffusion. We derive a simple method for calculating the committor function along paths that follow the reactive flux. Lastly, we provide guidance for the practical implementation of the dynamic string method.

TI Administration of vorinostat disrupts HIV-1 latency in patients on antiretroviral therapy SO NATURE LA English DT Article ID HISTONE DEACETYLASE INHIBITORS; SUBEROYLANILIDE HYDROXAMIC ACID; VALPROIC ACID; IN-VIVO; TYPE-1; EXPRESSION; INFECTION; CELLS; PCR; ACTIVATION AB Despite antiretroviral therapy, proviral latency of human immunodeficiency virus type 1 (HIV-1) remains a principal obstacle to curing the infection(1). Inducing the expression of latent genomes within resting CD4(+) T cells is the primary strategy to clear this reservoir(2,3). Although histone deacetylase inhibitors such as suberoylanilide hydroxamic acid (also known as vorinostat, VOR) can disrupt HIV-1 latency in vitro(4-6), the utility of this approach has never been directly proven in a translational clinical study of HIV-infected patients. Here we isolated the circulating resting CD4(+) T cells of patients in whom viraemia was fully suppressed by antiretroviral therapy, and directly studied the effect of VOR on this latent reservoir. In each of eight patients, a single dose of VOR increased both biomarkers of cellular acetylation, and simultaneously induced an increase in HIV RNA expression in resting CD4(+) cells (mean increase, 4.8-fold). This demonstrates that a molecular mechanism known to enforce HIV latency can be therapeutically targeted in humans, provides proof-of-concept for histone deacetylase inhibitors as a therapeutic class, and defines a precise approach to test novel strategies to attack and eradicate latent HIV infection directly.

CA Romicat-II Investigators TI Coronary CT Angiography versus Standard Evaluation in Acute Chest Pain SO NEW ENGLAND JOURNAL OF MEDICINE LA English DT Article ID COMPUTED TOMOGRAPHIC ANGIOGRAPHY; EMERGENCY-DEPARTMENT PATIENTS; DIAGNOSTIC PERFORMANCE; ARTERY-DISEASE; ASSISTED TOMOGRAPHY; TRIAL; ASSOCIATION; MULTICENTER; RADIATION; OUTCOMES AB BACKGROUND It is unclear whether an evaluation incorporating coronary computed tomographic angiography (CCTA) is more effective than standard evaluation in the emergency department in patients with symptoms suggestive of acute coronary syndromes. METHODS In this multicenter trial, we randomly assigned patients 40 to 74 years of age with symptoms suggestive of acute coronary syndromes but without ischemic electrocardiographic changes or an initial positive troponin test to early CCTA or to standard evaluation in the emergency department on weekdays during daylight hours between April 2010 and January 2012. The primary end point was length of stay in the hospital. Secondary end points included rates of discharge from the emergency department, major adverse cardiovascular events at 28 days, and cumulative costs. Safety end points were undetected acute coronary syndromes. RESULTS The rate of acute coronary syndromes among 1000 patients with a mean (+/- SD) age of 54 +/- 8 years (47% women) was 8%. After early CCTA, as compared with standard evaluation, the mean length of stay in the hospital was reduced by 7.6 hours (P<0.001) and more patients were discharged directly from the emergency department (47% vs. 12%, P<0.001). There were no undetected acute coronary syndromes and no significant differences in major adverse cardiovascular events at 28 days. After CCTA, there was more downstream testing and higher radiation exposure. The cumulative mean cost of care was similar in the CCTA group and the standard-evaluation group ($4,289 and $4,060, respectively; P = 0.65). CONCLUSIONS In patients in the emergency department with symptoms suggestive of acute coronary syndromes, incorporating CCTA into a triage strategy improved the efficiency of clinical decision making, as compared with a standard evaluation in the emergency department, but it resulted in an increase in downstream testing and radiation exposure with no decrease in the overall costs of care.

Arginine vasopressin (AVP) is among several factors reported to be abnormal. The role of AVP on anxiety is still unclear. In order to further investigate this causal relationship and its possible role in anxiogenesis, male rat pups were separated from their dams for 3 h daily (3hMS) from post-natal day (PND) 2 to PND15. Fos expression in AVP+ neurons in the hypothalamic paraventricular (PVN) and supraoptic nuclei (SON) triggered by 3hMS, and AVP-mRNA expression, were examined at PND10 and PND21 respectively, whereas AVP-mRNA expression, PVN and SON volumes and plasma AVP concentration were assessed in adulthood. Elevated plus maze test (EPM) and Vogel conflict test (VCT) were also performed to evaluate unconditioned and conditioned anxious states at PND70-75. At PND10, a single 3hMS event increased Fos expression in AVP+ neurons fourfold in PVN and six to twelvefold in SON. AVP-mRNA was over-expressed in whole hypothalamus, PVN and SON between 122% and 147% at PND21 and PND63. Volumes of AVP-PVN and AVP-SON measured at PND75 had marked increases as well as AVP plasma concentration at 12 h of water deprivation (WD). MS rats demonstrated a high conditioned anxious state under VCT paradigm whereas no difference was found under EPM. These data demonstrate direct relationships between enhanced AVP neuronal activation and a potentiated vasopressin system, and this latter one with high conditioned anxiety in MS male rats.

TI AN AGE-RELATED AXON TERMINAL PATHOLOGY AROUND THE FIRST OLFACTORY RELAY THAT INVOLVES AMYLOIDOGENIC PROTEIN OVEREXPRESSION WITHOUT PLAQUE FORMATION SO NEUROSCIENCE LA English DT Article DE aging; dementia; amyloidogenesis; axonal pathology; olfactory deficit ID MILD COGNITIVE IMPAIRMENT; A-BETA PEPTIDES; ALZHEIMERS-DISEASE; DOWNS-SYNDROME; PIRIFORM CORTEX; SENSORY NEURONS; TAU PATHOLOGY; MOUSE MODEL; IN-VIVO; BULB AB The glomeruli are the first synaptic relay on the olfactory pathway and play a basic role in smell perception. Glomerular degeneration occurs in humans with age and in Alzheimer's disease (AD). The glomeruli heavily express beta-amyloid precursor protein (APP), beta-secretase (BACE1) and gamma-secretase complex. However, extracellular beta-amyloid peptide (A beta) deposition occurs fairly rarely at this location in postmortem pathological studies. We sought to explore age-related glomerular changes that might link to alteration in amyloidogenic proteins and/or plaque pathogenesis in transgenic models of AD and humans. Focally increased BACE1 immunoreactivity (IR) in the glomerular layer was identified in several transgenic models, and characterized systematically in transgenic mice harboring five familiar AD-related mutations (5XFAD). These elements were co-labeled with antibodies against APP N-terminal (22C11) and A beta N-terminal (3D6, 6E10) and mid-sequence (4G8). They were not co-labeled with two A beta C-terminal antibodies (Ter40, Ter42), nor associated with extracellular amyloidosis. These profiles were further characterized to be most likely abnormal olfactory nerve terminals. Reduced glomerular area was detected in 6-12-month-old 5XFAD mice relative to non-transgenic controls, and in aged humans relative to young/adult controls, more robust in AD than aged subjects without cerebral amyloid and tau pathologies. The results suggest that olfactory nerve terminals may undergo age-related dystrophic and degenerative changes in AD model mice and humans, which are associated with increased labeling for amyloidogenic proteins but not local extracellular A beta deposition. The identified axon terminal pathology might affect neuronal signal transmission and integration at the first olfactory synaptic relay. (C) 2012 IBRO. Published by Elsevier Ltd. All rights reserved.

TI Iodine-131 Dose Dependent Gene Expression in Thyroid Cancers and Corresponding Normal Tissues Following the Chernobyl Accident SO PLOS ONE LA English DT Article ID POST-CHERNOBYL; IONIZING-RADIATION; EPIGENETIC MECHANISMS; PAPILLARY CARCINOMAS; GAMMA-IRRADIATION; IN-VITRO; EXPOSURE; CELLS; UKRAINE; REARRANGEMENTS AB The strong and consistent relationship between irradiation at a young age and subsequent thyroid cancer provides an excellent model for studying radiation carcinogenesis in humans. We thus evaluated differential gene expression in thyroid tissue in relation to iodine-131 (I-131) doses received from the Chernobyl accident. Sixty three of 104 papillary thyroid cancers diagnosed between 1998 and 2008 in the Ukrainian-American cohort with individual I-131 thyroid dose estimates had paired RNA specimens from fresh frozen tumor (T) and normal (N) tissue provided by the Chernobyl Tissue Bank and satisfied quality control criteria. We first hybridized 32 randomly allocated RNA specimen pairs (T/N) on 64 whole genome microarrays (Agilent, 4x44 K). Associations of differential gene expression (log(2)(T/N)) with dose were assessed using Kruskall-Wallis and trend tests in linear mixed regression models. While none of the genes withstood correction for the false discovery rate, we selected 75 genes with a priori evidence or P kruskall/P trend <0.0005 for validation by qRT-PCR on the remaining 31 RNA specimen pairs (T/N). The qRT-PCR data were analyzed using linear mixed regression models that included radiation dose as a categorical or ordinal variable. Eleven of 75 qRT-PCR assayed genes (ACVR2A, AJAP1, CA12, CDK12, FAM38A, GALNT7, LMO3, MTA1, SLC19A1, SLC43A3, ZNF493) were confirmed to have a statistically significant differential dose-expression relationship. Our study is among the first to provide direct human data on long term differential gene expression in relation to individual I-131 doses and to identify a set of genes potentially important in radiation carcinogenesis.

TI NR2C in the Thalamic Reticular Nucleus; Effects of the NR2C Knockout SO PLOS ONE LA English DT Article ID NMDA RECEPTOR SUBTYPES; RAT-BRAIN; REGIONAL EXPRESSION; SCHIZOPHRENIA; SUBUNIT; NEURONS AB NMDAR antagonists can evoke delta frequency bursting in the nucleus reticularis of the thalamus (nRT). The mechanism of this oscillation was determined; antagonist blocks an NR2C-like conductance that has low Mg block at resting potential and thus can contribute a resting inward current in response to ambient glutamate. Block of this current hyperpolarizes the cell, deinactivating T-type Ca channels and thus triggering delta frequency bursting. The basis for assuming a NR2C-like conductance was that (1) transcripts for NR2C are abundant in the thalamus and (2) the current-voltage curve of the synaptically evoked NMDAR current has the low rectification characteristic of NR2C. In the current study, we have sought to determine whether the channels that generate the NMDAR current are NR2C-like or are actually comprised of receptors containing NR2C. We studied the current-voltage curve of synaptically evoked NMDAR current in the nRT of NR2C knockout mice. In wild-type mice, the current was weakly voltage dependent, as previously observed in rats. This weak rectification was absent in NR2C KO mice. In contrast, NR2C KO had no effect on the strongly rectifying NMDAR current in pyramidal cells of the prefrontal cortex. These results demonstrate that the low rectification normally observed in the nRT is due to NR2C. C1 [Zhang, Yuchun; Lisman, John E.] Brandeis Univ, Dept Biol, Waltham, MA 02254 USA.

Such signals may be important for updating associative action representations within striatum. In order that the appropriate representations can be updated, it might be important for the RPE signal to be specific for the action that led to that error. However, RPEs signaled by midbrain dopamine neurons, which project heavily to striatum, are not action-specific. Here we tested whether RPE-like activity in dorsal striatum is action-specific; we recorded single-unit activity in posterior dorsomedial and dorsolateral striatum as rats performed a task in which the reward predictions associated with two different actions were repeatedly violated, thereby eliciting RPEs. We separately analyzed fast firing neurons (FFNs) and phasically firing neurons (total n = 1076). Only among FFNs recorded in posterior dorsomedial striatum did we find a population with RPE-like characteristics (19 of all 196 FFNs, 10%). This population showed a phasic increase in activity during unexpected rewards, a phasic decrease in activity during unexpected omission of rewards, and a phasic increase in activity during cues when they predicted high-value reward. However, unlike a classical RPE signal, this signal was linked to the action that elicited the prediction error, in that neurons tended to signal RPEs only after their anti-preferred action. This action-specific RPE-like signal could provide a mechanism for updating specific associative action representations in posterior dorsomedial striatum.

However, little is known about how single vmPFC neurons process the prediction and reception of rewards and punishments. We recorded from monkey vmPFC neurons in an experimental situation with alternating blocks, one in which rewards were delivered and one in which punishments were delivered. Many vmPFC neurons changed their activity between blocks. Importantly, neurons in ventral vmPFC were persistently more active in the appetitive "reward" block, whereas neurons in dorsal vmPFC were persistently more active in the aversive "punishment" block. Furthermore, within ventral vmPFC, posterior neurons phasically encoded probability of reward, whereas anterior neurons tonically encoded possibility of reward. We found multiple distinct nonlinear valuation mechanisms within the primate prefrontal cortex. Our findings suggest that different subregions of vmPFC contribute differentially to the processing of valence. By conveying such multidimensional and nonlinear signals, the vmPFC may enable flexible control of decisions and emotions to adapt to complex environments.

TI Risk of Cervical Precancer and Cancer Among HIV-Infected Women With Normal Cervical Cytology and No Evidence of Oncogenic HPV Infection SO JAMA-JOURNAL OF THE AMERICAN MEDICAL ASSOCIATION LA English DT Article ID HUMAN-PAPILLOMAVIRUS INFECTION; INTERAGENCY HIV; PREVENTION; DNA AB Context US cervical cancer screening guidelines for human immunodeficiency virus (HIV)-uninfected women 30 years or older have recently been revised, increasing the suggested interval between Papanicolaou (Pap) tests from 3 years to 5 years among those with normal cervical cytology (Pap test) results who test negative for oncogenic human papillomavirus (HPV). Whether a 3- year or 5-year screening interval could be used in HIV-infected women who are cytologically normal and oncogenic HPV-negative is unknown. Objective To determine the risk of cervical precancer or cancer defined cytologically (high-grade squamous intraepithelial lesions or greater [HSIL+]) or histologically (cervical intraepithelial neoplasia 2 or greater [CIN-2+]), as 2 separate end points, in HIV-infected women and HIV-uninfected women who at baseline had a normal Pap test result and were negative for oncogenic HPV. Design, Setting, and Participants Participants included 420 HIV-infected women and 279 HIV-uninfected women with normal cervical cytology at their enrollment in a multi-institutional US cohort of the Women's Interagency HIV Study, between October 1, 2001, and September 30, 2002, with follow-up through April 30, 2011. Semiannual visits at 6 clinical sites included Pap testing and, if indicated, cervical biopsy. Cervicovaginal lavage specimens from enrollment were tested for HPV DNA using polymerase chain reaction. The primary analysis was truncated at 5 years of follow-up. Main Outcome Measure Five-year cumulative incidence of cervical precancer and cancer. Results No oncogenic HPV was detected in 369 (88%[95% CI, 84%-91%]) HIV-infected women and 255 (91% [95% CI, 88%-94%]) HIV-uninfected women with normal cervical cytology at enrollment. Among these oncogenic HPV-negative women, 2 cases of HSIL+ were observed; an HIV-uninfected woman and an HIV-infected woman with a CD4 cell count of 500 cells/mu L or greater. Histologic data were obtained from 4 of the 6 clinical sites. There were 6 cases of CIN-2+ in 145 HIV-uninfected women(cumulative incidence, 5% [95% CI, 1%-8%]) and 9 cases in 219 HIV-infected women (cumulative incidence, 5% [95% CI, 2%-8%]). This included 1 case of CIN-2+ in 44 oncogenic HPV-negative HIV-infected women with CD4 cell count less than 350 cells/mu L (cumulative incidence, 2% [95% CI, 0%-7%]), 1 case in 47 women with CD4 cell count of 350 to 499 cells/mu L (cumulative incidence, 2% [95% CI, 0%-7%]), and 7 cases in 128 women with CD4 cell count of 500 cells/mu L or greater (cumulative incidence, 6% [95% CI, 2%-10%]). One HIV-infected and 1 HIV-uninfected woman had CIN-3, but none had cancer. Conclusion The 5-year cumulative incidence of HSIL+ and CIN-2+ was similar in HIV-infected women and HIV-uninfected women who were cytologically normal and oncogenic HPV-negative at enrollment.

The GLP-1 receptor (GLP-1R) is widely distributed in the central nervous system, however little is known about how GLP-1Rs regulate ambulatory behavior. The abused psychostimulant amphetamine (AMPH) promotes behavioral locomotor activity primarily by inducing the release of the neurotransmitter dopamine. Here, we identify the GLP-1R agonist exendin-4 (Ex-4) as a modulator of behavioral activation by AMPH. We report that in rats a single acute administration of Ex-4 decreases both basal locomotor activity as well as AMPH-induced locomotor activity. Ex-4 did not induce behavioral responses reflecting anxiety or aversion. Our findings implicate GLP-1R signaling as a novel modulator of psychostimulant-induced behavior and therefore a potential therapeutic target for psychostimulant abuse. (C) 2012 Elsevier Inc.

TI Analysis of high dimensional data using pre-defined set and subset information, with applications to genomic data SO BMC BIOINFORMATICS LA English DT Article ID GENE-EXPRESSION DATA; MICROARRAY DATA; ENRICHMENT ANALYSIS; GLOBAL TEST; ASSOCIATION; KNOWLEDGE AB Background: Based on available biological information, genomic data can often be partitioned into pre-defined sets (e. g. pathways) and subsets within sets. Biologists are often interested in determining whether some pre-defined sets of variables (e. g. genes) are differentially expressed under varying experimental conditions. Several procedures are available in the literature for making such determinations, however, they do not take into account information regarding the subsets within each set. Secondly, variables (e. g. genes) belonging to a set or a subset are potentially correlated, yet such information is often ignored and univariate methods are used. This may result in loss of power and/or inflated false positive rate. Results: We introduce a multiple testing-based methodology which makes use of available information regarding biologically relevant subsets within each pre-defined set of variables while exploiting the underlying dependence structure among the variables. Using this methodology, a biologist may not only determine whether a set of variables are differentially expressed between two experimental conditions, but may also test whether specific subsets within a significant set are also significant. Conclusions: The proposed methodology; (a) is easy to implement, (b) does not require inverting potentially singular covariance matrices, and (c) controls the family wise error rate (FWER) at the desired nominal level, (d) is robust to the underlying distribution and covariance structures. Although for simplicity of exposition, the methodology is described for microarray gene expression data, it is also applicable to any high dimensional data, such as the mRNA seq data, CpG methylation data etc. C1 [Peddada, Shyamal D.] NIEHS, Biostat Branch, Res Triangle Pk, NC 27709 USA.

In fact, formal investigations of this question, both by modelling between-country differences and studies of migrants, indicate that an appreciable amount of the international differences in this disease remains unexplained.

MuLV glyco-gag, gPr80(Gag), promotes retrovirus replication and disease progression. Although virtually all infectious MuLVs encode glyco-gag, XMRV (xenotropic murine leukemia virus-related virus) lacks the classical gPr80(Gag) sequence. We examined XMRV to determine if its leader sequence contains glyco-gag activity, whether the presence of conventional gPr80(Gag) affects replication of XMRV, and we describe the evolution of glyco-gag-deficient MuLVs in Mus. Results: We introduced several mutations disrupting two putative but noncanonical glyco-gag proteins in the leader sequence region in XMRV and found that those mutations did not affect virus release nor susceptibility to the antiviral activity of hA3G (human APOBEC3G). A chimeric XMRV encoding the Moloney MuLV (M-MuLV) leader sequence (MXMRV) demonstrated that M-MuLV glyco-gag facilitated MXMRV release and increased infectivity. Infectivity assays with several cell lines showed that glyco-gag increases XMRV infectivity in all cell lines tested, but the level of this increase varies in different cell lines. Because MuLV glyco-gag counteracts mouse APOBEC3, we investigated whether M-MuLV glyco-gag enhances XMRV infection by counteracting human APOBEC3. Comparison of hAPOBEC3 isoforms expressed in different cell lines indicated that hA3B was the most likely candidate for a restrictive hA3. However over-expression of hA3B showed no enhanced restriction of infection by XMRV compared to MXMRV. Endogenous MuLVs in the sequenced mouse genome were screened for canonical glyco-gag, which was identified in two clades of xenotropic MuLVs (X-MuLVs) and ecotropic MuLVs, but not in other X-MuLVs or in any polytropic MuLVs. Conclusions: M-MuLV glyco-gag facilitates XMRV replication, and the leader sequence region in XMRV does not encode proteins equivalent to M-MuLV glyco-gag. The fact that the ability of glyco-gag to enhance XMRV infection varies in different cell lines suggests a glyco-gag sensitive restrictive factor that further reduces XMRV infectivity. The M-MuLV glyco-gag enhancement for XMRV replication is through a hAPOBEC3 independent mechanism. The absence of glyco-gag in MuLVs carried by western European mice suggests that loss of this sequence is a relatively recent event with limited subspecies distribution.

The response of the dendritic cell inflammasome during Mtb infections has not been investigated in detail. Methodology/Principal Findings: Here we show that Mtb infection of bone marrow-derived dendritic cells (BMDCs) induces IL-1 beta secretion and that this induction is dependent upon the presence of functional ASC and NLRP3 but not NLRC4 or NOD2. The analysis of cell death induction in BMDCs derived from these knock-out mice revealed the important induction of host cell apoptosis but not necrosis, pyroptosis or pyronecrosis. Furthermore, NLRP3 inflammasome activation and apoptosis induction were both reduced in BMDCs infected with the esxA deletion mutant of Mtb demonstrating the importance of a functional ESX-1 secretion system. Surprisingly, caspase-1/11-deficient BMDCs still secreted residual levels of IL-1 beta and IL-18 upon Mtb infection which was abolished in cells infected with the esxA Mtb mutant. Conclusion: Altogether we demonstrate the partially caspase-1/11-independent, but NLRP3- and ASC-dependent IL-1 beta secretion in Mtb-infected BMDCs. These findings point towards a potential role of DCs in the host innate immune response to mycobacterial infections via their capacity to induce IL-1 beta and IL-18 secretion.

To find downstream targets of Rac1 that affect MT assembly dynamics, we performed an RNAi screen of 23 MT binding and regulatory factors and identified RNAi treatments that suppressed changes in MT dynamics induced by constitutively activated Rac1. By analyzing fluorescent EB3 dynamics with automated tracking, we found that RNAi treatments targeting p150(glued), APC2, spastin, EB1, Op18, or MARK2 blocked Rac1-mediated MT growth in lamellipodia. MARK2 was the only protein whose RNAi targeting additionally suppressed Rac1 effects on MT orientation in lamellipodia, and thus became the focus of further study. We show that GFP-MARK2 rescued effects of MARK2 depletion on MT growth lifetime and orientation, and GFP-MARK2 localized in lamellipodia in a Rac1-activity-dependent manner. In a wound-edge motility assay, MARK2-depleted cells failed to polarize their centrosomes or exhibit oriented MT growth in the leading edge, and displayed defects in directional cell migration. Thus, automated image analysis of MT assembly dynamics identified MARK2 as a target regulated downstream of Rac1 that promotes oriented MT growth in the leading edge to mediate directed cell migration.

Despite the ability of high-dose IFNa reducing relapse and mortality by up to 33%, large majority of patients experience side effects and toxicity which outweigh the benefits. The current study attempts to identify genetic markers likely to be associated with benefit from IFNa-2b treatment and predictive for survival. Experimental design: We tested the association of variants in FOXP3 microsatellites, CTLA4 SNPs and HLA genotype in 284 melanoma patients and their association with prognosis and survival of melanoma patients who received IFNa adjuvant therapy. Results: Univariate survival analysis suggested that patients bearing either the DRB1*15 or HLA-Cw7 allele suffered worse OS while patients bearing either HLA-Cw6 or HLA-B44 enjoyed better OS. DRB1*15 positive patients suffered also worse RFS and conversely HLA-Cw6 positive patients had better RFS. Multivariate analysis revealed that a five-marker genotyping signature was prognostic of OS independent of disease stage. In the multivariate Cox regression model, HLA-B38 (p = 0.021), HLA-C15 (p = 0.025), HLA-C3 (p = 0.014), DRB1*15 (p = 0.005) and CT60*G/G (0.081) were significantly associated with OS with risk ratio of 0.097 (95% CI, 0.013-0.709), 0.387 (95% CI, 0.169-0.889), 0.449 (95% CI, 0.237-0.851), 1.948 (95% CI, 1.221-3.109) and 1.484 (95% IC, 0.953-2.312) respectively. Conclusion: These results suggest that gene polymorphisms relevant to a biological occurrence are more likely to be informative when studied in concert to address potential redundant or conflicting functions that may limit each gene individual contribution. The five markers identified here exemplify this concept though prospective validation in independent cohorts is needed.

TI Interferon regulatory factor 8 integrates T-cell receptor and cytokine- signaling pathways and drives effector differentiation of CD8 T cells SO PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA LA English DT Article DE common gamma c-cytokine; T-cell receptor signaling; CD8 effector differentiation; transcription factors; Jak3 ID DEFECTIVE LYMPHOID DEVELOPMENT; CD8-ALPHA(+) DENDRITIC CELLS; SEQUENCE-BINDING-PROTEIN; MICE LACKING JAK3; TRANSCRIPTIONAL REGULATION; MEMORY; ACTIVATION; ICSBP; EXPRESSION; INDUCTION AB We recently demonstrated that differentiation of cytotoxic T cells requires cooperation between T-cell receptor (TCR)/costimulation and gamma c-cytokines. Here we demonstrate that the transcription factor IFN regulatory factor 8 (IRF8) is expressed in CD8 T cells by the combination of these two signals. More importantly, depletion of IRF8 in these cells abrogated the differentiation of naive CD8 T cells into effector cells in an experimental graft-vs.-host disease mouse model. We also show that IRF8 seems to not operate upstream of other critical factors such as T-bet and eomesodermin, which have been implicated in effector maturation. Collectively, our work shows that IRF8 integrates the TCR/costimulation and gamma c-cytokine- signaling pathways and mediates the transition of naive CD8 T cells to effector cells, thus identifying IRF8 as one of the molecular regulators of CD8 T-cell differentiation.

TI Neuregulin 1-ErbB4-PI3K signaling in schizophrenia and phosphoinositide 3-kinase-p110 delta inhibition as a potential therapeutic strategy SO PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA LA English DT Article DE neuregulin 3; AKT; development; neuroleptic ID NEUROPSYCHIATRIC DISORDERS; NEUROBLASTOMA TUMORS; HIPPOCAMPAL DAMAGE; DOPAMINE-RECEPTORS; GENETIC-VARIATION; ERBB4; EXPRESSION; ASSOCIATION; VARIANTS; ISOFORM AB Neuregulin 1 (NRG1) and ErbB4, critical neurodevelopmental genes, are implicated in schizophrenia, but the mediating mechanisms are unknown. Here we identify a genetically regulated, pharmacologically targetable, risk pathway associated with schizophrenia and with ErbB4 genetic variation involving increased expression of a PI3K-linked ErbB4 receptor (CYT-1) and the phosphoinositide 3-kinase subunit, p110 delta (PIK3CD). In human lymphoblasts, NRG1-mediated phosphatidyl-inositol, 3,4,5 triphosphate [PI(3,4,5)P3] signaling is predicted by schizophrenia-associated ErbB4 genotype and PIK3CD levels and is impaired in patients with schizophrenia. In human brain, the same ErbB4 genotype again predicts increased PIK3CD expression. Pharmacological inhibition of p110 delta using the small molecule inhibitor, IC87114, blocks the effects of amphetamine in a mouse pharmacological model of psychosis and reverses schizophrenia-related phenotypes in a rat neonatal ventral hippocampal lesion model. Consistent with these antipsychotic-like properties, IC87114 increases AKT phosphorylation in brains of treated mice, implicating a mechanism of action. Finally, in two family-based genetic studies, PIK3CD shows evidence of association with schizophrenia. Our data provide insight into a mechanism of ErbB4 association with schizophrenia; reveal a previously unidentified biological and disease link between NRG1-ErbB4, p110 delta, and AKT; and suggest that p110 delta is a previously undescribed therapeutic target for the treatment of psychiatric disorders.

It has been suggested that WM is the more robust process because it exploits long-termmemory (i.e., a current stimulus activates a stored representation of that stimulus, which can then be actively maintained). Recent studies have suggested that monkeys may be unable to store acoustic signals in long-term memory, raising the possibility that they may therefore also lack auditory WM. To explore this possibility, we tested rhesus monkeys on a serial delayed match-to-sample (DMS) task using a small set of sounds presented with similar to 1-s interstimulus delays. Performance was accurate whenever a match or a nonmatch stimulus followed the sample directly, but it fell precipitously if a single nonmatch stimulus intervened between sample and match. The steep drop in accuracy was found to be due not to passive decay of the sample's trace, but to retroactive interference from the intervening nonmatch stimulus. This "overwriting" effect was far greater than that observed previously in serial DMS with visual stimuli. The results, which accord with the notion that WM relies on long-termmemory, indicate that monkeys perform serial DMS in audition remarkably poorly and that whatever success they had on this task depended largely, if not entirely, on the retention of stimulus traces in the passive form of shortterm memory.

TI Nucleotide Excision DNA Repair Is Associated With Age-Related Vascular Dysfunction SO CIRCULATION LA English DT Article DE aging; cardiovascular diseases; endothelium; nitric oxide synthase; vasodilation ID SMOOTH-MUSCLE-CELLS; PROTEIN-KINASE-A; ENDOTHELIAL DYSFUNCTION; CARDIOVASCULAR-DISEASE; SHEAR-STRESS; SENESCENCE; HYPERTENSION; ATHEROSCLEROSIS; ACTIVATION; SYNTHASE AB Background-Vascular dysfunction in atherosclerosis and diabetes mellitus, as observed in the aging population of developed societies, is associated with vascular DNA damage and cell senescence. We hypothesized that cumulative DNA damage during aging contributes to vascular dysfunction. Methods and Results-In mice with genomic instability resulting from the defective nucleotide excision repair genes ERCC1 and XPD (Ercc1(d/-) and Xpd(TTD) mice), we explored age-dependent vascular function compared with that in wild-type mice. Ercc1(d/-) mice showed increased vascular cell senescence, accelerated development of vasodilator dysfunction, increased vascular stiffness, and elevated blood pressure at a very young age. The vasodilator dysfunction was due to decreased endothelial nitric oxide synthase levels and impaired smooth muscle cell function, which involved phosphodiesterase activity. Similar to Ercc1(d/-) mice, age-related endothelium-dependent vasodilator dysfunction in Xpd(TTD) animals was increased. To investigate the implications for human vascular disease, we explored associations between single-nucleotide polymorphisms of selected nucleotide excision repair genes and arterial stiffness within the AortaGen Consortium and found a significant association of a single-nucleotide polymorphism (rs2029298) in the putative promoter region of DDB2 gene with carotid-femoral pulse wave velocity. Conclusions-Mice with genomic instability recapitulate age-dependent vascular dysfunction as observed in animal models and in humans but with an accelerated progression compared with wild-type mice. In addition, we found associations between variations in human DNA repair genes and markers for vascular stiffness, which is associated with aging. Our study supports the concept that genomic instability contributes importantly to the development of cardiovascular disease. (Circulation. 2012;126:468-478.)

In the first instance we performed standard genome wide association analyses, and subsequent risk profile analysis. In addition we performed a series of analyses that involved testing measures of global relatedness within the cases compared to controls, searching for excess homozygosity in the cases, and examining the cases for signs of excess local genomic relatedness using a sliding window approach. This work suggested that the previously identified common, low risk alleles, and the risk models associated with these alleles, were generalizable to the Finnish Parkinson's disease population. However, we found no evidence that would suggest a single common high penetrance mutation exists in this cohort of young onset patients.

Thus, we hypothesized that central FAs are related to peripheral glucose regulation and energy expenditure in humans. To test this we measured FA species profiles in cerebrospinal fluid (CSF) and plasma of 32 individuals who stayed in our clinical inpatient unit for 6 days. Body composition was measured by dual energy X-ray absorptiometry and glucose regulation by an oral glucose test (OGTT) followed by measurements of 24 hour (24EE) and sleep energy expenditure (SLEEP) as well as respiratory quotient (RQ) in a respiratory chamber. CSF was obtained via lumbar punctures; FA concentrations were measured by liquid chromatography/mass spectrometry. As expected, FA concentrations were higher in plasma compared to CSF. Individuals with high concentrations of CSF very-long-chain saturated FAs had lower rates of SLEEP. In the plasma moderate associations of these FAs with higher 24EE were observed. Moreover, CSF monounsaturated long-chain FA (palmitoleic and oleic acid) concentrations were associated with lower RQs and lower glucose area under the curve during the OGTT. Thus, FAs in the CSF strongly correlated with peripheral metabolic traits. These physiological parameters were most specific to long-chain monounsaturated (C16:1, C18:1) and very-long-chain saturated (C24:0, C26:0) FAs. Conclusions: Together with previous animal experiments these initial cross-sectional human data indicate that central FA species are linked to peripheral glucose and energy homeostasis.

Semantic priming is manifested by faster and more accurate recognition of a word-target when preceded by a semantically related prime, relative to an unrelated prime condition. Compared to control, semantic priming in schizophrenics is characterized by reduced priming effects at long prime-target Stimulus Onset Asynchrony (SOA) and, sometimes, augmented priming at short SOA. In addition, unlike controls, schizophrenics consistently show indirect (mediated) priming (such as from the prime 'wedding' to the target 'finger', mediated by 'ring'). In a previous study, we developed a novel attractor neural network model with synaptic adaptation mechanisms that could account for semantic priming patterns in healthy individuals. Here, we examine the consequences of introducing attractor instability to this network, which is hypothesized to arise from dysfunctional synaptic transmission known to occur in schizophrenia. In two simulated experiments, we demonstrate how such instability speeds up the network's dynamics and, consequently, produces the full spectrum of priming effects previously reported in patients. The model also explains the inconsistency of augmented priming results at short SOAs using directly related pairs relative to the consistency of indirect priming. Further, we discuss how the same mechanism could account for other symptoms of the disease, such as derailment ('loose associations') or the commonly seen difficulty of patients in utilizing context. Finally, we show how the model can statistically implement the overly-broad wave of spreading activation previously presumed to characterize thought-disorders in schizophrenia.

TI The Transcription Factor NFATp Plays a Key Role in Susceptibility to TB in Mice SO PLOS ONE LA English DT Article ID TUMOR-NECROSIS-FACTOR; FACTOR-ALPHA GENE; MYCOBACTERIUM-TUBERCULOSIS INFECTION; CREB-BINDING-PROTEIN; IFN-GAMMA PRODUCTION; HUMAN B-CELLS; INTERFERON-GAMMA; TNF GENE; IN-VIVO; NUCLEAR FACTOR AB In T cells, the transcription factor nuclear factor of activated T cells p (NFATp) is a key regulator of the cytokine genes tumor necrosis factor (TNF) and interferon-gamma (IFN-gamma). Here, we show that NFATp-deficient (NFATp(-/-)) mice have a dramatic and highly significant increase in mortality after Mycobacterium tuberculosis (MTb) infection as compared to mortality of control animals after MTb infection. Animals deficient in NFATp have significantly impaired levels of TNF and IFN-gamma transcription and protein expression in naive or total CD4(+) T cells, but display wild-type levels of TNF mRNA or protein from MTb-stimulated dendritic cells (DC). The rapid mortality and disease severity observed in MTb-infected NFATp(-/-) mice is associated with dysregulated production of TNF and IFN-gamma in the lungs, as well as with increased levels of TNF, in their serum. Furthermore, global blocking of TNF production by injection of a TNF neutralizaing agent at 6 weeks, but not 12 weeks, post-MTb-infection further decreased the survival rate of both wild-type and NFATp(-/-) mice, indicating an early role for TNF derived from cells from the monocyte lineage in containment of infection. These results thus demonstrate that NFATp plays a critical role in immune containment of TB disease in vivo, through the NFATp-dependent expression of TNF and IFN-gamma in T cells.

Due to their ultrasmall size, these AuNPs are especially attractive in applications requiring delivery to crowded intracellular spaces in the cytosol and nucleus. For eventual use in vivo, ultrasmall AuNPs should ideally be monodisperse, since small variations in size may affect how they interact with cells and how they behave in the body. Here we report the synthesis of ultrasmall, uniform 144-atom AuNPs protected by p-mercaptobenzoic acid followed by ligand exchange with glutathione (GSH). Quantitative scanning transmission electron microscopy (STEM) reveals that the resulting GSH-coated nanoparticles (Au(GSH)) have a uniform mass distribution with cores that contain 134 gold atoms on average. Particle size dispersity is analyzed by analytical ultracentrifugation, giving a narrow distribution of apparent hydrodynamic diameter of 4.0 +/- 0.6 nm. To evaluate the nanoparticles intracellular fate, the cell-penetrating peptide TAT is attached noncovalently to Au(GSH), which is confirmed by fluorescence quenching and isothermal titration calorimetry. HeLa cells are then incubated with both Au(GSH) and the Au(GSH)-TAT complex, and imaged without silver enhancement of the AuNPs in unstained thin sections by STEM. This imaging approach enables unbiased detection and quantification of individual ultrasmall nanoparticles and aggregates in the cytoplasm and nucleus of the cells.

However, it is not known whether such changes can be detected and verified using routinely collected data. We examined the correlation between the weekly number and average age of cases using data on pre-vaccination measles and rotavirus. We show that age-incidence patterns can be observed and predicted for these childhood infections. Incorporating additional information about important features of the transmission dynamics improves the correspondence between model predictions and empirical data. We then explored whether knowledge of the age-incidence pattern can shed light on the epidemiological features of diseases of unknown aetiology, such as Kawasaki disease (KD). Our results indicate KD is unlikely to be triggered by a single acute immunizing infection, but is consistent with an infection of longer duration, a non-immunizing infection or co-infection with an acute agent and one with longer duration. Age-incidence patterns can lend insight into important epidemiological features of infections, providing information on transmission-relevant population mixing for known infections and clues about the aetiology of complex paediatric diseases.

The distance-dependent pair diffusion coefficient describes the hydrodynamic interactions between particles in a fluid that are central to theories of polymer and colloid dynamics. We determine D(r) from the propagators (Green's functions) of particle pairs obtained from molecular dynamics simulations. At distances exceeding similar to 3 molecular diameters, the calculated pair diffusion coefficients are in excellent agreement with predictions from exact macroscopic hydrodynamic theory for large Brownian particles suspended in a solvent bath, as well as the Oseen approximation. However, the asymptotic 1/r distance dependence of D(r) associated with hydrodynamic effects emerges only after the pair distance dynamics has been followed for relatively long times, indicating non-negligible memory effects in the pair diffusion at short times. Deviations of the calculated D(r) from the hydrodynamic models at short distances r reflect the underlying many-body fluid structure, and are found to be correlated to differences in the local available volume. The procedure used here to determine the pair diffusion coefficients can also be used for single-particle diffusion in confinement with spherical symmetry. (C) 2012 American Institute of Physics.

TI Improved precision of syndesmophyte measurement for the evaluation of ankylosing spondylitis using CT: a phantom and patient study SO PHYSICS IN MEDICINE AND BIOLOGY LA English DT Article ID SURFACE-BASED REGISTRATION; RADIOGRAPHIC PROGRESSION; SEGMENTATION AB Ankylosing spondylitis is a disease characterized by abnormal bone formation (syndesmophyte) at the margins of inter-vertebral disc spaces. Syndesmophyte growth is currently typically monitored by the visual inspection of radiographs. The limitations inherent to the modality (2D projection of a 3D object) and rater (qualitative human judgment) may compromise sensitivity. With newly available treatments, more precise measures of syndesmophytes are needed to determine whether treatment can slow rates of syndesmophyte growth. We previously presented a computer algorithm measuring syndesmophyte volumes and heights in the 3D space of CT scans. In this study, we present improvements to the original algorithm and evaluate the gain in precision as applied to an anthropomorphic vertebral phantom and patients. Each patient was scanned twice in one day, thus providing two syndesmophyte volume and height measures. The difference between those two measures (ideally zero) determines our algorithm's precision. The technical improvements to the algorithm decreased the mean volume difference (standard deviation) between scans from 3.01% (2.83%) to 1.31% (0.95%) and the mean height difference between scans from 3.16% (2.99%) to 1.56% (1.13%). The high precision of the improved algorithm holds promise for application to longitudinal clinical studies.

Algorithms to identify CNVs through SNP-array platforms are available. The ability to evaluate well-characterized CNVs such as GSTM1 (1p13.3) deletion provides an important opportunity to assess their performance. Results: 773 cases and 759 controls from the SBC/EPICURO Study were genotyped in the GSTM1 region using TaqMan, Multiplex Ligation-dependent Probe Amplification (MLPA), and Illumina Infinium 1 M SNP-array platforms. CNV callings provided by TaqMan and MLPA were highly concordant and replicated the association between GSTM1 and bladder cancer. This was not the case when CNVs were called using Illumina 1 M data through available algorithms since no deletion was detected across the study samples. In contrast, when the Log R Ratio (LRR) was used as a continuous measure for the 5 probes contained in this locus, we were able to detect their association with bladder cancer using simple regression models or more sophisticated methods such as the ones implemented in the CNVtools package. Conclusions: This study highlights an important limitation in the CNV calling from SNP-array data in regions of common aberrations and suggests that there may be added advantage for using LRR as a continuous measure in association tests rather than relying on calling algorithms.

However, their roles have been poorly characterized. Here, we investigated the role of peroxiredoxin II in mouse erythropoiesis. Loss of Prx II significantly increased apoptosis and cell cycle arrest leading to abnormal erythropoiesis at 3 weeks of age when erythropoietin levels were almost same between wild type and Prx II-/-. In Prx II-/- bone marrow cells, DNA tail length as an indicator of the oxidative damage was greatly increased and mRNAs of the molecules associated with DNA damage and repair and transcription regulators of antioxidant enzymes were also significantly increased. In addition, N-Acetyl-L-Cysteine treatment significantly decreased immature erythroblasts and apoptotic cells increased in Prx II-/- BMCs. These results strongly demonstrate that Prx II plays an essential role in maintaining normal erythropoiesis by protecting DNA damage. (C) 2012 Elsevier Inc. All rights reserved.

TI MicroRNAs in the Pineal Gland miR-483 REGULATES MELATONIN SYNTHESIS BY TARGETING ARYLALKYLAMINE N-ACETYLTRANSFERASE SO JOURNAL OF BIOLOGICAL CHEMISTRY LA English DT Article ID SEROTONIN N-ACETYLTRANSFERASE; MESSENGER-RNAS; MOUSE RETINA; EXPRESSION; RAT; GENES; IDENTIFICATION; RHYTHM; AANAT; DIFFERENTIATION AB MicroRNAs (miRNAs) play a broad range of roles in biological regulation. In this study, rat pineal miRNAs were profiled for the first time, and their importance was evaluated by focusing on the main function of the pineal gland, melatonin synthesis. Massively parallel sequencing and related methods revealed the miRNA population is dominated by a small group of miRNAs as follows: similar to 75% is accounted for by 15 miRNAs; miR-182 represents 28%. In addition to miR-182, miR-183 and miR-96 are also highly enriched in the pineal gland, a distinctive pattern also found in the retina. This effort also identified previously unrecognized miRNAs and other small noncoding RNAs. Pineal miRNAs do not exhibit a marked night/day difference in abundance with few exceptions (e. g. 2-fold night/day differences in the abundance of miR-96 and miR-182); this contrasts sharply with the dynamic 24-h pattern that characterizes the pineal transcriptome. During development, the abundance of most pineal gland-enriched miRNAs increases; however, there is a marked decrease in at least one, miR-483. miR-483 is a likely regulator of melatonin synthesis, based on the following. It inhibits melatonin synthesis by pinealocytes in culture; it acts via predicted binding sites in the 3'-UTR of arylalkylamine N-acetyltransferase (Aanat) mRNA, the penultimate enzyme in melatonin synthesis, and it exhibits a developmental profile opposite to that of Aanat transcripts. Additionally, a miR-483 targeted antagonist increased melatonin synthesis in neonatal pinealocytes. These observations support the hypothesis that miR-483 suppresses Aanat mRNA levels during development and that the developmental decrease in miR-483 abundance promotes melatonin synthesis.

TI Characterization and Solution Structure of Mouse Myristoylated Methionine Sulfoxide Reductase A SO JOURNAL OF BIOLOGICAL CHEMISTRY LA English DT Article ID PROTEIN AB Methionine sulfoxide reductase A is an essential enzyme in the antioxidant system which scavenges reactive oxygen species through cyclic oxidation and reduction of methionine and methionine sulfoxide. The cytosolic form of the enzyme is myristoylated, but it is not known to translocate to membranes, and the function of myristoylation is not established. We compared the biochemical and biophysical properties of myristoylated and nonmyristoylated mouse methionine sulfoxide reductase A. These were almost identical for both forms of the enzyme, except that the myristoylated form reduced methionine sulfoxide in protein much faster than the nonmyristoylated form. We determined the solution structure of the myristoylated protein and found that the myristoyl group lies in a relatively surface exposed "myristoyl nest." We propose that this structure functions to enhance protein-protein interaction.

TI A Low pK(a) Cysteine at the Active Site of Mouse Methionine Sulfoxide Reductase A SO JOURNAL OF BIOLOGICAL CHEMISTRY LA English DT Article ID NEISSERIA-MENINGITIDIS; HYDROGEN-PEROXIDE; ESCHERICHIA-COLI; ANTIOXIDANT DEFENSE; CATALYTIC MECHANISM; OXIDATIVE STRESS; PROTEIN; ENZYME; MSRA; ACID AB Methionine sulfoxide reductase A is an essential enzyme in the antioxidant system which scavenges reactive oxygen species through cyclic oxidation and reduction of methionine and methionine sulfoxide. Recently it has also been shown to catalyze the reverse reaction, oxidizing methionine residues to methionine sulfoxide. A cysteine at the active site of the enzyme is essential for both reductase and oxidase activities. This cysteine has been reported to have a pK(a) of 9.5 in the absence of substrate, decreasing to 5.7 upon binding of substrate. Using three independent methods, we show that the pK(a) of the active site cysteine of mouse methionine sulfoxide reductase is 7.2 even in the absence of substrate. The primary mechanism by which the pK(a) is lowered is hydrogen bonding of the active site Cys-72 to protonated Glu-115. The low pK(a) renders the active site cysteine susceptible to oxidation to sulfenic acid by micromolar concentrations of hydrogen peroxide. This characteristic supports a role for methionine sulfoxide reductase in redox signaling.

Paul TI Association Between Colonoscopy and Colorectal Cancer Mortality in a US Cohort According to Site of Cancer and Colonoscopist Specialty SO JOURNAL OF CLINICAL ONCOLOGY LA English DT Article ID RANDOMIZED CONTROLLED TRIAL; NEGATIVE COLONOSCOPY; SCREENING COLONOSCOPY; UNITED-STATES; POPULATION; SIGMOIDOSCOPY; PROTECTION; RISK; SURVEILLANCE; PREDICTORS AB Purpose We designed this study to evaluate the association of colonoscopy with colorectal cancer (CRC) death in the United States by site of CRC and endoscopist specialty. Methods We designed a case-control study using Surveillance, Epidemiology, and End Results (SEER)-Medicare data. We identified patients (cases) diagnosed with CRC age 70 to 89 years from January 1998 through December 2002 who died as a result of CRC by 2007. We selected three matched controls without cancer for each case. Controls were assigned a referent date (date of diagnosis of the case). Colonoscopy performed from January 1991 through 6 months before the diagnosis/referent date was our primary exposure. We compared exposure to colonoscopy in cases and controls by using conditional logistic regression controlling for covariates, stratified by site of CRC. We determined endoscopist specialty by linkage to the American Medical Association (AMA) Masterfile. We assessed whether the association between colonoscopy and CRC death varied with endoscopist specialty. Results We identified 9,458 cases (3,963 proximal [41.9%], 4,685 distal [49.5%], and 810 unknown site [8.6%]) and 27,641 controls. In all, 11.3% of cases and 23.7% of controls underwent colonoscopy more than 6 months before diagnosis. Compared with controls, cases were less likely to have undergone colonoscopy (odds ratio [OR], 0.40; 95% CI, 0.37 to 0.43); the association was stronger for distal (OR, 0.24; 95% CI, 0.21 to 0.27) than proximal (OR, 0.58; 95% CI, 0.53 to 0.64) CRC. The strength of the association varied with endoscopist specialty. Conclusion Colonoscopy is associated with a reduced risk of death from CRC, with the association considerably and consistently stronger for distal versus proximal CRC. The overall association was strongest if colonoscopy was performed by a gastroenterologist.

The surface-exposed O-specific polysaccharide (O-SP) of the lipopolysaccharide of this bacterium is considered both;l virulence factor and a protective antigen. It is built up of the linear tetrasaccharide repeating unit [3)-alpha-L-Rhap-(1 -> 2)-alpha-D-Glcp-(1 -> 3)-alpha-D-GlcNAcp-(1 -> 3)-alpha-L-Rhap-(1 ->] differing from that of the O-SP of Shigella dysenteriae type 1 (SD) only in that the latter contains a D-Galp residue in place of the glucose moiety of the former. The close similarity of the O-SPs of these bacteria indicated a possible cross-reactivity, To answer this question we synthesized several oligosaccharide fragments of E. coli 0148 O-SP, up to a dodecasaccharide, as well as their bovine serum albumin or recombinant diphtheria toxin conjugates. Immunization of mice with these conjugates induced anti-O-SP-specific serum IgG antibody responses. The antisera reacted equally well with the LPSs of both bacteria, indicating cross-reactivity between the SD and E. coli 0148 O-SPs that was further supported by Western-blot and dot-blot analyses, as well as by inhibition of binding between the antisera and the O-SPs of both bacteria.

TI The Transcription Profile of Tax-3 Is More Similar to Tax-1 than Tax-2: Insights into HTLV-3 Potential Leukemogenic Properties SO PLOS ONE LA English DT Article ID T-CELL LEUKEMIA; VIRUS TYPE-I; NF-KAPPA-B; DAVID BIOINFORMATICS RESOURCES; TROPICAL SPASTIC PARAPARESIS; NUCLEAR EXPORT SIGNAL; DOMAIN-BINDING MOTIF; LARGE GENE LISTS; LYMPHOTROPIC-VIRUS; TYPE-1 HTLV-1 AB Human T-cell Lymphotropic Viruses type 1 (HTLV-1) is the etiological agent of Adult T-cell Leukemia/Lymphoma. Although associated with lymphocytosis, HTLV-2 infection is not associated with any malignant hematological disease. Similarly, no infection-related symptom has been detected in HTLV-3-infected individuals studied so far. Differences in individual Tax transcriptional activity might account for these distinct physiopathological outcomes. Tax-1 and Tax-3 possess a PDZ binding motif in their sequence. Interestingly, this motif, which is critical for Tax-1 transforming activity, is absent from Tax-2. We used the DNA microarray technology to analyze and compare the global gene expression profiles of different T- and non T-cell types expressing Tax-1, Tax-2 or Tax-3 viral transactivators. In a T-cell line, this analysis allowed us to identify 48 genes whose expression is commonly affected by all Tax proteins and are hence characteristic of the HTLV infection, independently of the virus type. Importantly, we also identified a subset of genes (n = 70) which are specifically up-regulated by Tax-1 and Tax-3, while Tax-1 and Tax-2 shared only 1 gene and Tax-2 and Tax-3 shared 8 genes. These results demonstrate that Tax-3 and Tax-1 are closely related in terms of cellular gene deregulation. Analysis of the molecular interactions existing between those Tax-1/Tax-3 deregulated genes then allowed us to highlight biological networks of genes characteristic of HTLV-1 and HTLV-3 infection. The majority of those up-regulated genes are functionally linked in biological processes characteristic of HTLV-1-infected T-cells expressing Tax such as regulation of transcription and apoptosis, activation of the NF-kappa B cascade, T-cell mediated immunity and induction of cell proliferation and differentiation. In conclusion, our results demonstrate for the first time that, in T-and non T-cells types, Tax-3 is a functional analogue of Tax-1 in terms of transcriptional activation and suggest that HTLV-3 might share pathogenic features with HTLV-1 in vivo.

Relaxation of the circular, double-stranded mtDNA relies on the presence of topoisomerase activity. Three different topoisomerases have been identified in mitochondria: Top1mt, Top3 alpha and a truncated form of Top2 beta. Methodology/Principal Findings: The present study shows the importance of Top1mt in mitochondrial homeostasis. Here we show that Top1mt(-/-) murine embryonic fibroblasts (MEF) exhibit dysfunctional mitochondrial respiration, which leads decreased ATP production and compensation by increased glycolysis and fatty acid oxidation. ROS production in Top1mt(-/-) MEF cells is involved in nuclear DNA damage and induction of autophagy. Lack of Top1mt also triggers oxidative stress and DNA damage associated with lipid peroxidation and mitophagy in Top1mt(-/-) mice. Conclusion/Significance: Together, our data implicate Top1mt for mitochondrial integrity and energy metabolism. The compensation mechanism described here contributes to the survival of Top1mt(-/-) cells and mice despite alterations of mitochondrial functions and metabolism. Therefore, this study supports a novel model for cellular adaptation to mitochondrial damage.

TI Molecular Imaging Reveals a Progressive Pulmonary Inflammation in Lower Airways in Ferrets Infected with 2009 H1N1 Pandemic Influenza Virus SO PLOS ONE LA English DT Article ID A H1N1; RECEPTOR SPECIFICITY; VIRAL-INFECTIONS; AVIAN INFLUENZA; CELL TROPISM; HEMAGGLUTININ; BINDING; D222G; SUBSTITUTION; TOMOGRAPHY AB Molecular imaging has gained attention as a possible approach for the study of the progression of inflammation and disease dynamics. Herein we used [F-18]-2-deoxy-2-fluoro-D-glucose ([F-18]-FDG) as a radiotracer for PET imaging coupled with CT (FDG-PET/CT) to gain insight into the spatiotemporal progression of the inflammatory response of ferrets infected with a clinical isolate of a pandemic influenza virus, H1N1 (H1N1pdm). The thoracic regions of mock-and H1N1pdm-infected ferrets were imaged prior to infection and at 1, 2, 3 and 6 days post-infection (DPI). On 1 DPI, FDG-PET/CT imaging revealed areas of consolidation in the right caudal lobe which corresponded with elevated [F-18]-FDG uptake (maximum standardized uptake values (SUVMax), 4.7-7.0). By days 2 and 3, consolidation (CT) and inflammation ([F-18]-FDG) appeared in the left caudal lobe. By 6 DPI, CT images showed extensive areas of patchy ground-glass opacities (GGO) and consolidations with the largest lesions having high SUVMax (6.0-7.6). Viral shedding and replication were detected in most nasal, throat and rectal swabs and nasal turbinates and lungs on 1, 2 and 3 DPI, but not on day 7, respectively. In conclusion, molecular imaging of infected ferrets revealed a progressive consolidation on CT with corresponding [F-18]-FDG uptake. Strong positive correlations were measured between SUVMax and bronchiolitis-related pathologic scoring (Spearman's rho = 0.75). Importantly, the extensive areas of patchy GGO and consolidation seen on CT in the ferret model at 6 DPI are similar to that reported for human H1N1pdm infections. In summary, these first molecular imaging studies of lower respiratory infection with H1N1pdm show that FDG-PET can give insight into the spatiotemporal progression of the inflammation in real-time.

Assessment of HER2 expression in vivo would advance development of new HER2-targeted therapeutic agents and, potentially, facilitate choice of the proper treatment strategy offered to the individual patient. We present novel HER2-specific probes for in vivo evaluation of the receptor status by near-infrared (NIR) optical imaging. Experimental Design: Affibody molecules were expressed, purified, and labeled with NIR-fluorescent dyes. The binding affinity and specificity of the obtained probe were tested in vitro. For in vivo validation, the relationship of the measured NIR signal and HER2 expression was characterized in four breast cancer xenograft models, expressing different levels of HER2. Accumulation of Affibody molecules in tumor tissue was further confirmed by ex vivo analysis. Results: Affibody-DyLight conjugates showed high affinity to HER2 (K-D = 3.66 +/- 0.26). No acute toxicity resulted from injection of the probes (up to 0.5 mg/kg) into mice. Pharmacokinetic studies revealed a relatively short (37.53 +/- 2.8 min) half-life of the tracer in blood. Fluorescence accumulation in HER2-positive BT-474 xenografts was evident as soon as a few minutes post injection and reached its maximum at 90 minutes. On the other hand, no signal retention was observed in HER2-negative MDA-MB-468 xenografts. Immunostaining of extracted tumor tissue confirmed penetration of the tracer into tumor tissue. Conclusions: The results of our studies suggest that Affibody-DyLight-750 conjugate is a powerful tool to monitor HER2 status in a preclinical setting. Following clinical validation, it might provide complementary means for assessment of HER2 expression in breast cancer patients (assuming availability of proper NIR scanners) and/or be used to facilitate detection of HER2-positive metastatic lesions during NIR-assisted surgery.

The specialized histone H3 variant CENP-A provides an epigenetic and structural basis for chromosome segregation by replacing H3 at centromeres. Unlike exclusively octameric canonical H3 nucleosomes, CENP-A nucleosomes have been shown to exist as octamers, hexamers, and tetramers. An intriguing possibility reconciling these observations is that CENP-A nucleosomes cycle between octamers and tetramers in vivo. We tested this hypothesis by tracking CENP-A nucleosomal components, structure, chromatin folding, and covalent modifications across the human cell cycle. We report that CENP-A nucleosomes alter from tetramers to octamers before replication and revert to tetramers after replication. These structural transitions are accompanied by reversible chaperone binding, chromatin fiber folding changes, and previously undescribed modifications within the histone fold domains of CENP-A and H4. Our results reveal a cyclical nature to CENP-A nucleosome structure and have implications for the maintenance of epigenetic memory after centromere replication.

The heptapeptide facilitates McC transport into susceptible cells, where it is processed releasing a non-hydrolyzable aminoacyl adenylate that inhibits an essential aminoacyl-tRNA synthetase. The self-immunity gene mccF encodes a specialized serine peptidase that cleaves an amide bond connecting the peptidyl or aminoacyl moieties of, respectively, intact and processed McC with the nucleotidyl moiety. Most mccF orthologs from organisms other than E. coli are not linked to the McC biosynthesis gene cluster. Here, we show that a protein product of one such gene, MccF from Bacillus anthracis (BaMccF), is able to cleave intact and processed McC, and we present a series of structures of this protein. Structural analysis of apo-BaMccF and its adenosine monophosphate complex reveals specific features of MccF-like peptidases that allow them to interact with substrates containing nucleotidyl moieties. Sequence analyses and phylogenetic reconstructions suggest that several distinct subfamilies form the MccF clade of the large S66 family of bacterial serine peptidases. We show that various representatives of the MccF clade can specifically detoxify non-hydrolyzable aminoacyl adenylates differing in their aminoacyl moieties. We hypothesize that bacterial mccF genes serve as a source of bacterial antibiotic resistance. (C) 2012 Elsevier Ltd. All rights reserved.

TACE is an effective treatment for inoperable hepatic tumors, especially hypervascular tumors such as hepatocellular carcinoma. Recently, drug eluting beads (DEBs), in which a uniform embolic material is loaded with a drug and delivered in a single image-guided step, have been developed to reduce the variability in a TACE procedure. DEB-TACE results in localization of drug to targeted tumors while minimizing systemic exposure to chemotherapeutics. Once localized in the tissue, drug is eluted from the DEB in a controlled manner and penetrates hundreds of microns of tissue from the DEB surface. Necrosis is evident surrounding a DEB in tissue days to months after therapy; however, the contribution of drug and ischemia is currently unknown. Future advances in DEB technology may include image-ability, DEB size tailored to tumor anatomy and drug combinations. (C) 2012 Elsevier B.V. All rights reserved.

To further understand the neurobiological functions of En2, we conducted neuroanatomical expression profiling of En2 wildtype mice. RTQPCR assays demonstrated that En2 is expressed in adult brain structures including the somatosensory cortex, hippocampus, striatum, thalamus, hypothalamus and brainstem. Human genetic studies indicate that EN2 is associated with autism. To determine the consequences of En2 mutations on mouse behaviors, including outcomes potentially relevant to autism, we conducted comprehensive phenotyping of social, communication, repetitive, and cognitive behaviors. En2 null mutants exhibited robust deficits in reciprocal social interactions as juveniles and adults, and absence of sociability in adults, replicated in two independent cohorts. Fear conditioning and water maze learning were impaired in En2 null mutants. High immobility in the forced swim test, reduced prepulse inhibition, mild motor coordination impairments and reduced grip strength were detected in En2 null mutants. No genotype differences were found on measures of ultrasonic vocalizations in social contexts, and no stereotyped or repetitive behaviors were observed. Developmental milestones, general health, olfactory abilities, exploratory locomotor activity, anxiety-like behaviors and pain responses did not differ across genotypes, indicating that the behavioral abnormalities detected in En2 null mutants were not attributable to physical or procedural confounds. Our findings provide new insight into the role of En2 in complex behaviors and suggest that disturbances in En2 signaling may contribute to neuropsychiatric disorders marked by social and cognitive deficits, including autism spectrum disorders.

TI Selective Endothelial Overexpression of Arginase II Induces Endothelial Dysfunction and Hypertension and Enhances Atherosclerosis in Mice SO PLOS ONE LA English DT Article ID NITRIC-OXIDE SYNTHASE; LOW-DENSITY-LIPOPROTEIN; VASCULAR ENDOTHELIUM; ARGININE METABOLISM; OXIDATIVE STRESS; TRANSGENIC MICE; CAROTID-ARTERY; CELLS; INHIBITION; EXPRESSION AB Background: Cardiovascular disorders associated with endothelial dysfunction, such as atherosclerosis, have decreased nitric oxide (NO) bioavailability. Arginase in the vasculature can compete with eNOS for L-arginine and has been implicated in atherosclerosis. The aim of this study was to evaluate the effect of endothelial-specific elevation of arginase II expression on endothelial function and the development of atherosclerosis. Methodology/Principal Findings: Transgenic mice on a C57BL/6 background with endothelial-specific overexpression of human arginase II (hArgII) gene under the control of the Tie2 promoter were produced. The hArgII mice had elevated tissue arginase activity except in liver and in resident peritoneal macrophages, confirming endothelial specificity of the transgene. Using small-vessel myography, aorta from these mice exhibited endothelial dysfunction when compared to their non-transgenic littermate controls. The blood pressure of the hArgII mice was 17% higher than their littermate controls and, when crossed with apoE -/- mice, hArgII mice had increased aortic atherosclerotic lesions. Conclusion: We conclude that overexpression of arginase II in the endothelium is detrimental to the cardiovascular system.

Upon delivery into gastric epithelial cells, CagA localizes to the inner face of the plasma membrane, where it acts as a pathogenic scaffold/hub that promiscuously recruits host proteins to potentiate oncogenic signaling. We find that CagA comprises a structured N-terminal region and an intrinsically disordered C-terminal region that directs versatile protein interactions. X-ray crystallographic analysis of the N-terminal CagA fragment (residues 1-876) revealed that the region has a structure comprised of three discrete domains. Domain I constitutes a mobile CagA N terminus, while Domain II tethers CagA to the plasma membrane by interacting with membrane phosphatidylserine. Domain III interacts intramolecularly with the intrinsically disordered C-terminal region, and this interaction potentiates the pathogenic scaffold/hub function of CagA.

TI Preserving Immunogenicity of Lethally Irradiated Viral and Bacterial Vaccine Epitopes Using a Radio-Protective Mn2+-Peptide Complex from Deinococcus SO CELL HOST & MICROBE LA English DT Article ID VENEZUELAN EQUINE ENCEPHALITIS; STAPHYLOCOCCUS-AUREUS; RADIATION-RESISTANCE; IONIZING-RADIATION; ESCHERICHIA-COLI; GAMMA-RADIATION; PROTEIN DAMAGE; RADIODURANS; IMMUNITY; DNA AB Although pathogen inactivation by gamma-radiation is an attractive approach for whole-organism vaccine development, radiation doses required to ensure sterility also destroy immunogenic protein epitopes needed to mount protective immune responses. We demonstrate the use of a reconstituted manganous peptide complex from the radiation-resistant bacterium Deinococcus radiodurans to protect protein epitopes from radiation-induced damage and uncouple it from genome damage and organism killing. The Mn2+ complex preserved antigenic structures in aqueous preparations of bacteriophage lambda, Venezuelan equine encephalitis virus, and Staphylococcus aureus during supralethal irradiation (25-40 kGy). An irradiated vaccine elicited both antibody and Th17 responses, and induced B and T cell-dependent protection against methicillin-resistant S. aureus (MRSA) in mice. Structural integrity of viruses and bacteria are shown to be preserved at radiation doses far above those which abolish infectivity. This approach could expedite vaccine production for emerging and established pathogens for which no protective vaccines exist.

Thomson, Elizabeth TI Comprehensive molecular characterization of human colon and rectal cancer SO NATURE LA English DT Article ID COLORECTAL-CANCER; INTESTINAL EPITHELIUM; SOMATIC MUTATIONS; HUMAN BREAST; WILMS-TUMOR; GENE; DIFFERENTIATION; ONCOGENE; CELLS; WTX AB To characterize somatic alterations in colorectal carcinoma, we conducted a genome-scale analysis of 276 samples, analysing exome sequence, DNA copy number, promoter methylation and messenger RNA and microRNA expression. A subset of these samples (97) underwent low-depth-of-coverage whole-genome sequencing. In total, 16% of colorectal carcinomas were found to be hypermutated: three-quarters of these had the expected high microsatellite instability, usually with hypermethylation and MLH1 silencing, and one-quarter had somatic mismatch-repair gene and polymerase e (POLE) mutations. Excluding the hypermutated cancers, colon and rectum cancers were found to have considerably similar patterns of genomic alteration. Twenty-four genes were significantly mutated, and in addition to the expected APC, TP53, SMAD4, PIK3CA and KRAS mutations, we found frequent mutations in ARID1A, SOX9 and FAM123B. Recurrent copy-number alterations include potentially drug-targetable amplifications of ERBB2 and newly discovered amplification of IGF2. Recurrent chromosomal translocations include the fusion of NAV2 and WNT pathway member TCF7L1. Integrative analyses suggest new markers for aggressive colorectal carcinoma and an important role for MYC-directed transcriptional activation and repression.

TI Analysis of Plasmodium falciparum diversity in natural infections by deep sequencing SO NATURE LA English DT Article ID PAPUA-NEW-GUINEA; MALARIA PARASITE; LIBRARY PREPARATION; GENOME; RESISTANCE; TRANSMISSION; POLYMORPHISM; EVOLUTION; SELECTION; PATTERNS AB Malaria elimination strategies require surveillance of the parasite population for genetic changes that demand a public health response, such as new forms of drug resistance(1,2). Here we describe methods for the large-scale analysis of genetic variation in Plasmodium falciparum by deep sequencing of parasite DNA obtained from the blood of patients with malaria, either directly or after short-term culture. Analysis of 86,158 exonic single nucleotide polymorphisms that passed genotyping quality control in 227 samples from Africa, Asia and Oceania provides genome-wide estimates of allele frequency distribution, population structure and linkage disequilibrium. By comparing the genetic diversity of individual infections with that of the local parasite population, we derive a metric of within-host diversity that is related to the level of inbreeding in the population. An open-access web application has been established for the exploration of regional differences in allele frequency and of highly differentiated loci in the P. falciparum genome.

CA Consortium Food Allergy Res CoFAR TI Oral Immunotherapy for Treatment of Egg Allergy in Children SO NEW ENGLAND JOURNAL OF MEDICINE LA English DT Article ID COWS MILK ALLERGY; FOOD ALLERGY; NONANAPHYLACTIC CHILDREN; TOLERANCE INDUCTION; PEANUT ALLERGY; DOUBLE-BLIND; DESENSITIZATION; MECHANISMS; EFFICACY; EXTRACT AB BACKGROUND For egg allergy, dietary avoidance is the only currently approved treatment. We evaluated oral immunotherapy using egg-white powder for the treatment of children with egg allergy. METHODS In this double-blind, randomized, placebo-controlled study, 55 children, 5 to 11 years of age, with egg allergy received oral immunotherapy (40 children) or placebo (15). Initial dose-escalation, build-up, and maintenance phases were followed by an oral food challenge with egg-white powder at 10 months and at 22 months. Children who successfully passed the challenge at 22 months discontinued oral immunotherapy and avoided all egg consumption for 4 to 6 weeks. At 24 months, these children underwent an oral food challenge with egg-white powder and a cooked egg to test for sustained unresponsiveness. Children who passed this challenge at 24 months were placed on a diet with ad libitum egg consumption and were evaluated for continuation of sustained unresponsiveness at 30 months and 36 months. RESULTS After 10 months of therapy, none of the children who received placebo and 55% of those who received oral immunotherapy passed the oral food challenge and were considered to be desensitized; after 22 months, 75% of children in the oral-immunotherapy group were desensitized. In the oral-immunotherapy group, 28% (11 of 40 children) passed the oral food challenge at 24 months and were considered to have sustained unresponsiveness. At 30 months and 36 months, all children who had passed the oral food challenge at 24 months were consuming egg. Of the immune markers measured, small wheal diameters on skin-prick testing and increases in egg-specific IgG4 antibody levels were associated with passing the oral food challenge at 24 months. CONCLUSIONS These results show that oral immunotherapy can desensitize a high proportion of children with egg allergy and induce sustained unresponsiveness in a clinically significant subset.

TI Structural Differences between Human Proteins and Aero- and Microbial Allergens Define Allergenicity SO PLOS ONE LA English DT Article ID MANSONI EGG ANTIGENS; ASCARIS-LUMBRICOIDES; CHILDHOOD ASTHMA; CROSS-REACTIVITY; TH2 RESPONSES; HAY-FEVER; IGE; INFECTION; SCHISTOSOMIASIS; SENSITIZATION AB The current paradigm suggests that structural homology of allergenic proteins to microbial (particularly helminths) or human proteins underlie their allergenic nature. To examine systematically the structural relationships among allergens and proteins of pathogens (helminths, protozoans, fungi and bacteria) as they relate to allergenicity, we compared the amino acid sequence of 499 molecularly-defined allergens with the predicted proteomes of fifteen known pathogens, including Th2 inducing helminths and Th1-inducing protozoans, and humans using a variety of bioinformatic tools. Allergenicity was assessed based on IgE prevalences using publicly accessible databases and the literature. We found multiple homologues of common allergens among proteins of helminths, protozoans, fungi and humans, but not of bacteria. In contrast, 187 allergens showed no homology with any of the microbial genera studied. Interestingly, allergens without homologues or those with limited levels of sequence conservation were the most allergenic displaying high IgE prevalences in the allergic population. There was an inverse relationship between allergenicity and amino acid conservation levels with either parasite, including helminth, or human proteins. Our results suggest that allergenicity may be associated with the relative "uniqueness" of an antigen, i.e. immunogenicity, while similarity would lead to immunological tolerance.

Molecular-dynamics simulations show that in the closed state, the channel conductance is similar to 12 orders-of-magnitude lower than in the open state. This large drop in conductance is remarkable because even in the functionally closed conformation the pore constriction remains wide enough for the passage of sodium ions, aided by a continuous bridge of similar to 12 water molecules. However, we find that the free energy cost of hydrating the hydrophobic gate is large, accounting almost entirely for the energetic barrier blocking ion passage. The free energies of transferring a sodium ion into a prehydrated gate in functionally closed and open states differ by only 1.2 kcal/mol, compared to an 11 kcal/mol difference in the costs of hydrating the hydrophobic gate. Conversely, ion desolvation effects play only minor roles in GLIC ion channel gating. Our simulations help rationalize experiments probing the gating kinetics of the nicotinic acetylcholine receptor in response to mutations of pore-lining residues. The molecular character and phase behavior of water should thus be included in quantitative descriptions of ion channel gating.

TI Identification of a novel Wnt5a-CK1 epsilon-Dvl2-Plk1-mediated primary cilia disassembly pathway SO EMBO JOURNAL LA English DT Article DE Cilia; CK1; Dvl2; Plk1; Wnt ID POLO-LIKE KINASE-1; BETA-CATENIN; CELL-CYCLE; BOX DOMAIN; I FAMILY; PROTEIN-KINASE; MITOTIC ENTRY; WNT; CILIOGENESIS; PLK1 AB Non-motile primary cilium is an antenna-like structure whose defect is associated with a wide range of pathologies, including developmental disorders and cancer. Although mechanisms regulating cilia assembly have been extensively studied, how cilia disassembly is regulated remains poorly understood. Here, we report unexpected roles of Dishevelled 2 (Dvl2) and interphase polo-like kinase 1 (Plk1) in primary cilia disassembly. We demonstrated that Dvl2 is phosphorylated at S143 and T224 in a manner that requires both non-canonical Wnt5a ligand and casein kinase 1 epsilon (CK1 epsilon), and that this event is critical to interact with Plk1 in early stages of the cell cycle. The resulting Dvl2-Plk1 complex mediated Wnt5a-CK1 epsilon-Dvl2-dependent primary cilia disassembly by stabilizing the HEF1 scaffold and activating its associated Aurora-A (AurA), a kinase crucially required for primary cilia disassembly. Thus, via the formation of the Dvl2-Plk1 complex, Plk1 plays an unanticipated role in primary cilia disassembly by linking Wnt5a-induced biochemical steps to HEF1/AurA-dependent cilia disassembly. This study may provide new insights into the mechanism underlying ciliary disassembly processes and various cilia-related disorders.

TI Rapid Evolution of HIV-1 to Functional CD8(+) T Cell Responses in Humanized BLT Mice SO SCIENCE TRANSLATIONAL MEDICINE LA English DT Article ID HUMAN-IMMUNODEFICIENCY-VIRUS; ANTIGEN-PRESENTING CELLS; HUMAN IMMUNE-SYSTEM; CLASS-I ALLELES; LYMPHOCYTE ESCAPE; TYPE-1 INFECTION; REVERSE-TRANSCRIPTASE; CYNOMOLGUS MACAQUES; VACCINE DESIGN; MOUSE MODEL AB The development of mouse/human chimeras through the engraftment of human immune cells and tissues into immunodeficient mice, including the recently described humanized BLT (bone marrow, liver, thymus) mouse model, holds great promise to facilitate the in vivo study of human immune responses. However, little data exist regarding the extent to which cellular immune responses in humanized mice accurately reflect those seen in humans. We infected humanized BLT mice with HIV-1 as a model pathogen and characterized HIV-1-specific immune responses and viral evolution during the acute phase of infection. HIV-1-specific CD8(+) T cell responses in these mice were found to closely resemble those in humans in terms of their specificity, kinetics, and immunodominance. Viral sequence evolution also revealed rapid and highly reproducible escape from these responses, mirroring the adaptations to host immune pressures observed during natural HIV-1 infection. Moreover, mice expressing the protective HLA-B*57 allele exhibited enhanced control of viral replication and restricted the same CD8(+) T cell responses to conserved regions of HIV-1 Gag that are critical to its control of HIV-1 in humans. These data reveal that the humanized BLT mouse model appears to accurately recapitulate human pathogen-specific cellular immunity and the fundamental immunological mechanisms required to control a model human pathogen, aspects critical to the use of a small-animal model for human pathogens.

Objective To determine the effect of silymarin on liver disease activity in patients with chronic hepatitis C virus (HCV) infection unsuccessfully treated with interferon-based therapy. Design, Setting, and Participants Multicenter, double-blind, placebo-controlled trial conducted at 4 medical centers in the United States. Participants included 154 persons with chronic HCV infection and serum alanine aminotransferase (ALT) levels of 65 U/L or greater who were previously unsuccessfully treated with interferon-based therapy. Enrollment began in May 2008 and was completed in May 2010, with the last follow-up visit completed in March 2011. Intervention Participants were randomly assigned to receive 420-mg silymarin, 700-mg silymarin, or matching placebo administered 3 times per day for 24 weeks. Main Outcome Measures The primary outcome measure was serum ALT level of 45 U/L or less (considered within the normal range) or less than 65 U/L, provided this was at least a 50% decline from baseline values. Secondary outcomes included changes in ALT levels, HCV RNA levels, and quality-of-life measures. Results After 24 weeks of treatment, only 2 participants in each treatment group(P >= .99) met the primary outcome measure (3.8% [95% CI, 0.5% to 13.2%] for placebo, 4.0% [95% CI, 0.5% to 13.7%] for 420-mg silymarin, and 3.8% [95% CI, 0.5% to 13.2%] for 700-mg silymarin). The mean decline in serum ALT activity at the end of treatment did not differ significantly (P=.75) across the 3 treatment groups (mean decline, -4.3 [95% CI, -17.3 to 8.7] U/L for placebo, -14.4 [95% CI, -41.6 to 12.7] U/L for 420-mg silymarin, -11.3 [95% CI, -27.9 to 5.4] U/L for 700-mg silymarin); there likewise were no significant differences in HCV RNA levels (mean change, 0.07 [95% CI, -0.05 to 0.18] log(10) IU/mL for placebo, -0.03[95% CI, -0.18 to 0.12] log(10) IU/mL for 420-mg silymarin, 0.04 [95% CI, -0.08 to 0.16] log(10) IU/mL for 700-mg silymarin; P=.54) or quality-of-life measures. The adverse event profile of silymarin was comparable with that of placebo. Conclusion Higher than customary doses of silymarin did not significantly reduce serum ALT levels more than placebo in participants with chronic HCV infection unsuccessfully treated with interferon-based therapy.

In the United States, however, control of tuberculosis has been increasingly successful. Only 3.2% of the US population is estimated to have latent tuberculosis and there are only 11 000 cases annually of active disease. More than half the cases in this country occur in individuals born outside the United States. Human immunodeficiency virus coinfection is not a major factor in the United States, since only approximately 10% of cases are coinfected. Drug resistance is also uncommon in this country. Because the United States has more resources for the diagnosis, therapy, and public health control of tuberculosis than many regions of the world, and because many hospitals have more cases of clinically significant nontuberculous mycobacteria than tuberculosis, the management approaches to tuberculosis need to be quite different in this country than in other regions. The resurgence in interest in developing new tools and the investment in public health infrastructure will hopefully be sustained in the United States so that the effect of tuberculosis on the US population will continue to diminish, and these new tools and approaches can be adapted to both high and low prevalence areas to meet the global challenge.

Methodology/Principal Findings: We demonstrate that a novel member of the mitochondrial transporter protein family, Anopheles gambiae mitochondrial carrier 1 (AgMC1), is required to maintain mitochondrial membrane potential in mosquito midgut cells and modulates epithelial responses to Plasmodium infection. AgMC1 silencing reduces mitochondrial membrane potential, resulting in increased proton-leak and uncoupling of oxidative phosphorylation. These metabolic changes reduce midgut ROS generation and increase A. gambiae susceptibility to Plasmodium infection. Conclusion: We provide direct experimental evidence indicating that ROS derived from mitochondria can modulate mosquito epithelial responses to Plasmodium infection. C1 [Goncalves, Renata L.

All seem to rely on complementary actions of two closely related catecholaminergic neuromodulators, dopamine (DA), and noradrenaline (NA). We compared single unit activity of dopaminergic neurons of the substantia nigra pars compacta (SNc) and noradrenergic neurons of the locus coeruleus (LC) in monkeys performing a reward schedule task. Their motivation, indexed using operant performance, increased as they progressed through schedules ending in reward delivery. The responses of dopaminergic and noradrenergic neurons around the time of major task events, visual cues predicting trial outcome and operant action to complete a trial were similar in that they occurred at the same time. They were also similar in that they both responded most strongly to the first cues in schedules, which are the most informative cues. The neuronal responses around the time of the monkeys' actions were different, in that the response intensity profiles changed in opposite directions. Dopaminergic responses were stronger around predictable rewarded correct actions whereas noradrenergic responses were greater around predictably unrewarded correct actions. The complementary response profiles related to the monkeys operant actions suggest that DA neurons might relate to the value of the current action whereas the noradrenergic neurons relate to the psychological cost of that action.

TI Ultrasensitive Detection of Cancer Biomarkers in the Clinic by Use of a Nanostructured Microfluidic Array SO ANALYTICAL CHEMISTRY LA English DT Article ID SQUAMOUS-CELL CARCINOMA; ENDOTHELIAL GROWTH-FACTOR; ORAL-CANCER; VEGF-C; FACTOR RECEPTOR; HEAD; NECK; SERUM; PROTEINS; INTERLEUKIN-6 AB Multiplexed biomarker protein detection holds unrealized promise for clinical cancer diagnostics due to lack of suitable measurement devices and lack of rigorously validated protein panels. Here we report an ultrasensitive electrochemical microfluidic array optimized to measure a four-protein panel of biomarker proteins, and we validate the protein panel for accurate oral cancer diagnostics. Unprecedented ultralow detection into the 5-50 fg.mL(-1) range was achieved for simultaneous measurement of proteins interleukin 6 (IL-6), IL-8, vascular endothelial growth factor (VEGF), and VEGF-C in diluted serum. The immunoarray achieves high sensitivity in 50 min assays by using off-line protein capture by magnetic beads carrying 400 000 enzyme labels and similar to 100 000 antibodies. After capture of the proteins and washing to inhibit nonspecific binding, the beads are magnetically separated and injected into the array for selective capture by antibodies on eight nanostructured sensors. Good correlations with enzyme-linked immunosorbent assays (ELISA) for protein determinations in conditioned cancer cell media confirmed the accuracy of this approach. Normalized means of the four protein levels in 78 oral cancer patient serum samples and 49 controls gave clinical sensitivity of 89% and specificity of 98% for oral cancer detection, demonstrating high diagnostic utility. The low-cost, easily fabricated immunoarray provides a rapid Serum test for diagnosis and personalized therapy of oral cancer. The device is readily adaptable to clinical diagnostics of other cancers. C1 [Malhotra, Ruchika; Chikkaveeraiah, Bhaskara V.; Rusling, James F.] Univ Connecticut, Dept Chem, Storrs, CT USA.

TI Two Forkhead Transcription Factors Regulate the Division of Cardiac Progenitor Cells by a Polo-Dependent Pathway SO DEVELOPMENTAL CELL LA English DT Article ID DROSOPHILA EMBRYONIC MESODERM; GROWTH-FACTOR RECEPTOR; HEART DEVELOPMENT; GENE TINMAN; BOX GENES; FATES; GENOME; NUMB; CARDIOGENESIS; MELANOGASTER AB The development of a complex organ requires the specification of appropriate numbers of each of its constituent cell types, as well as their proper differentiation and correct positioning relative to each other. During Drosophila cardiogenesis, all three of these processes are controlled by jumeau (jumu) and Checkpoint suppressor homologue (CHES-1-like), two genes encoding forkhead transcription factors that we discovered utilizing an integrated genetic, genomic, and computational strategy for identifying genes expressed in the developing Drosophila heart. Both jumu and CHES-1-like are required during asymmetric cell division for the derivation of two distinct cardiac cell types from their mutual precursor and in symmetric cell divisions that produce yet a third type of heart cell. jumu and CHES-1-like control the division of cardiac progenitors by regulating the activity of Polo, a kinase involved in multiple steps of mitosis. This pathway demonstrates how transcription factors integrate diverse developmental processes during organogenesis.

TI Complex Patterns of Human Antisera Reactivity to Novel 2009 H1N1 and Historical H1N1 Influenza Strains SO PLOS ONE LA English DT Article ID ADAMANTANE RESISTANCE; VIRUS; VACCINE; ORIGIN; ANTIBODIES; IMMUNITY; PROTECTION; GENE; H3N2 AB Background: During the 2009 influenza pandemic, individuals over the age of 60 had the lowest incidence of infection with approximately 25% of these people having pre-existing, cross-reactive antibodies to novel 2009 H1N1 influenza isolates. It was proposed that older people had pre-existing antibodies induced by previous 1918-like virus infection(s) that cross-reacted to novel H1N1 strains. Methodology/Principal Findings: Using antisera collected from a cohort of individuals collected before the second wave of novel H1N1 infections, only a minority of individuals with 1918 influenza specific antibodies also demonstrated hemagglutination-inhibition activity against the novel H1N1 influenza. In this study, we examined human antisera collected from individuals that ranged between the ages of 1 month and 90 years to determine the profile of seropositive influenza immunity to viruses representing H1N1 antigenic eras over the past 100 years. Even though HAI titers to novel 2009 H1N1 and the 1918 H1N1 influenza viruses were positively associated, the association was far from perfect, particularly for the older and younger age groups. Conclusions/Significance: Therefore, there may be a complex set of immune responses that are retained in people infected with seasonal H1N1 that can contribute to the reduced rates of H1N1 influenza infection in older populations.

The phage named SpaA1 is morphologically similar to phages of the family Siphoviridae. The 42,784 bp genome of SpaA1 is a linear, double-stranded DNA molecule with 39 protruding cohesive ends. The SpaA1 genome encompasses 63 predicted protein-coding genes which cluster within three regions of the genome, each of apparently different origin, in a mosaic pattern. In two of these regions, the gene sets resemble those in prophages of Bacillus thuringiensis kurstaki str. T03a001 (genes involved in DNA replication/transcription, cell entry and exit) and B. cereus AH676 (additional regulatory and recombination genes), respectively. The third region represents an almost complete genome (except for the short terminal segments) of a distinct bacteriophage, MZTP02. Nearly the same gene module was identified in prophages of B. thuringiensis serovar monterrey BGSC 4AJ1 and B. cereus Rock4-2. These findings suggest that MZTP02 can be shuttled between genomes of other bacteriophages and prophages, leading to the formation of chimeric genomes. The presence of a complete phage genome in the genome of other phages apparently has not been described previously and might represent a 'fast track' route of virus evolution and horizontal gene transfer. Another phage (BceA1) nearly identical in sequence to SpaA1, and also including the almost complete MZTP02 genome within its own genome, was isolated from a bacterium of the B. cereus/B. thuringiensis group. Remarkably, both SpaA1 and BceA1 phages can infect B. cereus and B. thuringiensis, but only one of them, SpaA1, can infect S. pasteuri. This finding is best compatible with a scenario in which MZTP02 was originally contained in BceA1 infecting Bacillus spp, the common hosts for these two phages, followed by emergence of SpaA1 infecting S. pasteuri.

These proteins are composed of an Fv that reacts with cancer cells joined to a portion of Pseudomonas exotoxin A, which kills the cell. Because the toxin is a foreign protein, it can induce neutralizing antibodies and thereby limit the number of doses a patient can receive. We previously identified seven major mouse B-cell epitopes in the toxin, and subsequently silenced them using point mutations that converted large hydrophilic amino acids to alanine, yet retained full antitumor activity. Here we present results in which we identify and silence human B-cell epitopes in the RIT HA22. We obtained B cells from patients with antibodies to RITs, isolated the corresponding variable fragments (Fvs), and constructed a phage-display library containing Fvs that bind to the RITs. We then used alanine scanning mutagenesis to locate the epitopes. We found that human and mouse epitopes frequently overlap but are not identical. Most mutations that remove mouse epitopes did not remove human epitopes. Using the epitope information, we constructed a variant immunotoxin, HA22-LR-LO10, which has low reactivity with human antisera, yet has high cytotoxic and antitumor activity and can be given to mice at high doses without excess toxicity. The toxin portion of this RIT (LR-LO10) can be used with Fvs targeting other cancer antigens and is suitable for clinical development.

Design: An open-label pilot study of LPV/r monotherapy in participants on first-line nonnucleoside reverse transcriptase inhibitor three-drug combination ART with plasma HIV-1 RNA 1000-200 000 copies/ml. Methods: Participants were recruited from five sites in Africa and Asia within the AIDS Clinical Trials Group (ACTG) network. All participants received LPV/r 400/100mg twice daily. The primary endpoint was remaining on LPV/r monotherapy without virologic failure at week 24. Participants with virologic failure were offered addition of emtricitabine and tenofovir (FTC/TDF) to LPV/r. Results: Mutations associated with drug resistance were encountered in nearly all individuals screened for the study. One hundred and twenty-three participants were enrolled, and 122 completed 24 weeks on study. A high proportion remained on LPV/r monotherapy without virologic failure at 24 weeks (87%). Archived samples with HIV-1 RNA levels less than 400 copies/ml at week 24 (n = 102) underwent ultrasensitive assay. Of these individuals, 62 had levels less than 40 copies/ml and 30 had levels 40200 copies/ml. Fifteen individuals experienced virologic failure, among whom 11 had resistance assessed and two had emergent protease inhibitor mutations. Thirteen individuals with virologic failure added FTC/TDF and one individual added FTC/TDF without virologic failure. At study week 48, 11 of 14 adding FTC/TDF had HIV-1 RNA levels less than 400 copies/ml. Conclusion: In this pilot study conducted in diverse RLS, LPV/r monotherapy as second-line ART demonstrated promising activity.

To understand the immunochemistry of abacavir drug reactions, we investigated the effects of abacavir on HLA-B*57:01 epitope-binding in vitro and the quality and quantity of self-peptides presented by HLA-B*57:01 from abacavir-treated cells. Design and methods: An HLA-B*57:01-specific epitope-binding assay was developed to test for effects of abacavir, didanosine or flucloxacillin on self-peptide binding. To examine whether abacavir alters the peptide repertoire in HLA-B*57:01, a B-cell line secreting soluble human leucocyte antigen (sHLA) was cultured in the presence or absence of abacavir, peptides were eluted from purified human leucocyte antigen (HLA), and the peptide epitopes comparatively mapped by mass spectroscopy to identify drug-unique peptides. Results: Abacavir, but not didansosine or flucloxacillin, enhanced binding of the FITC-labeled self-peptide LF9 to HLA-B*57:01 in a dose-dependent manner. Endogenous peptides isolated from abacavir-treated HLA-B*57:01 B cells showed amino acid sequence differences compared with peptides from untreated cells. Novel drug-induced peptides lacked typical carboxyl (C) terminal amino acids characteristic of the HLA-B*57:01 peptide motif and instead contained predominantly isoleucine or leucine residues. Drug-induced peptides bind to soluble HLA-B*57:01 with high affinity that was not altered by abacavir addition. Conclusion: Our results support a model of drug-induced autoimmunity in which abacavir alters the quantity and quality of self-peptide loading into HLAB*57:01. Drug-induced loading of novel self-peptides into HLA, possibly by abacavir either altering the binding cleft or modifying the peptide-loading complex, generates an array of neo-antigen peptides that drive polyclonal T-cell autoimmune responses and multiorgan systemic toxicity.

To determine whether compensation in the production of downstream effectors by one pathway when the other is disrupted can explain these findings, we examined cytokine/chemokine expression and inflammatory infiltrates in wild-type (WT), MyD88(-/-) and TRIF-mutant mice following permanent middle cerebral artery occlusion (pMCAO). Methods: Cytokine/chemokine expression was measured with a 25-plex bead array in the serum and brains of all three groups of mice at baseline (no surgery/naive) and at 3 hours and 24 hours following pMCAO. Brain inflammatory and neutrophil infiltrates were examined 24 hours following pMCAO. Results: IL-6, keratinocyte chemoattractant (KC), granulocyte colony-stimulating factor (G-CSF) and IL-10 were significantly decreased in MyD88(-/-) mice compared to WT mice following pMCAO. Significantly, decreased levels of the neutrophil chemoattractants KC and G-CSF corresponded with a trend toward fewer neutrophils in the brains of MyD88(-/-) mice. IP-10 was significantly decreased when either pathway was disrupted. MIP-1 alpha was significantly decreased in TRIF-mutant mice, consistent with TRIF-dependent production. MyD88(-/-) mice showed elevations of a number of Th2 cytokines, such as IL-13, at baseline, which became significantly decreased following pMCAO. Conclusions: Both MyD88 and TRIF mediate pathway-specific cytokine production following focal cerebral ischemia. Our results also suggest a compensatory Th2-type skew at baseline in MyD88(-/-) mice and a paradoxical switch to a Th1 phenotype following focal cerebral ischemia. The MyD88 pathway directs the expression of neutrophil chemoattractants following cerebral ischemia.

Amphibian metamorphosis is totally dependent on T3 and offers a unique opportunity to study how T3 controls postembryonic development in vertebrates. Earlier studies have demonstrated that TR mediates the metamorphic effects of T3 in Xenopus laevis. Liganded TR recruits histone modifying coactivator complexes to target genes during metamorphosis. This leads to nucleosomal removal and histone modifications, including methylation of histone H3 lysine (K) 79, in the promoter regions, and the activation of T3-inducible genes. Results: We show that Dot1L, the only histone methyltransferase capable of methylating H3K79, is directly regulated by TR via binding to a T3 response element in the promoter region during metamorphosis in Xenopus tropicalis, a highly related species of Xenopus laevis. We further show that Dot1L expression in both the intestine and tail correlates with the transformation of the organs. Conclusions: Our findings suggest that TR activates Dot1L, which in turn participates in metamorphosis through a positive feedback to enhance H3K79 methylation and gene activation by liganded TR.

In addition to direct damage due to feeding, some tick species serve as the vectors for the causative agents of several diseases, such as the spirochetes of the genus Borrelia causing Lyme disease, the virus of tick-borne encephalitis, various Rickettsial pathogens or even protozoan parasites like Babesia spp. Hard ticks are unique among bloodfeeders because of their prolonged feeding period that may last up to two weeks. During such a long period of blood uptake, the host develops a wide range of mechanisms to prevent blood loss. The arthropod ectoparasite, in turn, secretes saliva in the sites of bite that assists blood feeding. Indeed, tick saliva represents a rich source of proteins with potent pharmacologic action that target different mechanisms of coagulation, platelet aggregation and vasoconstriction. Tick adaptation to their vertebrate hosts led to the inclusion of a powerful protein armamentarium in their salivary secretion that has been investigated by high-throughput methods. The resulting knowledge can be exploited for the isolation of novel antihemostatic agents. Here we review the tick salivary antihemostatics and their characterized functions at the molecular and cellular levels. (c) 2012 Elsevier B.V. All rights reserved.

Methods: Functional imaging with a 3-Tesla magnetic resonance scanner was performed on 18 patients and 17 controls during non-symptom producing tasks requiring right-handed individuated or coupled finger control. A global linear model and psychophysiologic interaction model compared individuated to coupled tasks for patients and controls separately, and the results were submitted to a group analysis. The sensorimotor (posterior) and associative (anterior) parts of the putamen were considered as seed regions for the connectivity analysis. Results: Compared to controls, patients had significant differences in activations and connectivity during individuated compared to coupled tasks: (i) decreased activations in the bilateral postcentral gyri, right associative posterior parietal areas, right cerebellum and left posterior putamen, while activations in the left anterior putamen were not different; (ii) increased connectivity of the left posterior putamen with the left cerebellum and left sensorimotor cortex; and (iii) increased connectivity of the left anterior putamen with bilateral supplementary motor areas, the left premotor cortex, and left cerebellum. Interpretation: Decreased activations in the sensorimotor putamen and cerebellum controlling the affected hand might underlie low levels of surround inhibition during individuated tasks. For identical motor performance in both groups, increased connectivity of sensorimotor and associative striato-cortical circuits in FHD suggests that both affected and unaffected territories of the striatum participate in compensatory processes.

TI Epidemiological Characteristics and Underlying Risk Factors for Mortality during the Autumn 2009 Pandemic Wave in Mexico SO PLOS ONE LA English DT Article ID INFLUENZA-A H1N1; CRITICALLY-ILL PATIENTS; VIRUS-INFECTION; CLINICAL CHARACTERISTICS; ANTIBODY-RESPONSES; UNITED-STATES; VACCINE; HOSPITALIZATION; A(H1N1); DISEASE AB Background: Elucidating the role of the underlying risk factors for severe outcomes of the 2009 A/H1N1 influenza pandemic could be crucial to define priority risk groups in resource-limited settings in future pandemics. Methods: We use individual-level clinical data on a large series of ARI (acute respiratory infection) hospitalizations from a prospective surveillance system of the Mexican Social Security medical system to analyze clinical features at presentation, admission delays, selected comorbidities and receipt of seasonal vaccine on the risk of A/H1N1-related death. We considered ARI hospitalizations and inpatient-deaths, and recorded demographic, geographic, and medical information on individual patients during August-December, 2009. Results: Seasonal influenza vaccination was associated with a reduced risk of death among A/H1N1 inpatients (OR = 0.43 (95% CI: 0.25, 0.74)) after adjustment for age, gender, geography, antiviral treatment, admission delays, comorbidities and medical conditions. However, this result should be interpreted with caution as it could have been affected by factors not directly measured in our study. Moreover, the effect of antiviral treatment against A/H1N1 inpatient death did not reach statistical significance (OR = 0.56 (95% CI: 0.29, 1.10)) probably because only 8.9% of A/H1N1 inpatients received antiviral treatment. Moreover, diabetes (OR = 1.6) and immune suppression (OR = 2.3) were statistically significant risk factors for death whereas asthmatic persons (OR = 0.3) or pregnant women (OR = 0.4) experienced a reduced fatality rate among A/H1N1 inpatients. We also observed an increased risk of death among A/H1N1 inpatients with admission delays >2 days after symptom onset (OR = 2.7). Similar associations were also observed for A/H1N1-negative inpatients. Conclusions: Geographical variation in identified medical risk factors including prevalence of diabetes and immune suppression may in part explain between-country differences in pandemic mortality burden. Furthermore, access to care including hospitalization without delay and antiviral treatment and are also important factors, as well as vaccination coverage with the 2008-09 trivalent inactivated influenza vaccine.

However, the information usually resides in unwieldy databases, limiting ready data analysis and integration. One resource that offers substantial potential for improvement in this regard is the NCI-60 cell line database compiled by the U.S. National Cancer Institute, which has been extensively characterized across numerous genomic and pharmacologic response platforms. In this report, we introduce a CellMiner (http://discover.nci.nih.gov/cellminer/) web application designed to improve the use of this extensive database. CellMiner tools allowed rapid data retrieval of transcripts for 22,379 genes and 360 microRNAs along with activity reports for 20,503 chemical compounds including 102 drugs approved by the U.S. Food and Drug Administration. Converting these differential levels into quantitative patterns across the NCI-60 clarified data organization and cross-comparisons using a novel pattern match tool. Data queries for potential relationships among parameters can be conducted in an iterative manner specific to user interests and expertise. Examples of the in silico discovery process afforded by CellMiner were provided for multidrug resistance analyses and doxorubicin activity; identification of colon-specific genes, microRNAs, and drugs; microRNAs related to the miR-17-92 cluster; and drug identification patterns matched to erlotinib, gefitinib, afatinib, and lapatinib. CellMiner greatly broadens applications of the extensive NCI-60 database for discovery by creating web-based processes that are rapid, flexible, and readily applied by users without bioinformatics expertise.

TI Histone Deacetylase Inhibitors Influence Chemotherapy Transport by Modulating Expression and Trafficking of a Common Polymorphic Variant of the ABCG2 Efflux Transporter SO CANCER RESEARCH LA English DT Article ID TRANSMEMBRANE CONDUCTANCE REGULATOR; CYSTIC-FIBROSIS; PHARMACOLOGICAL CHAPERONES; MULTIDRUG TRANSPORTER; ENDOPLASMIC-RETICULUM; AGGRESOME FORMATION; P-GLYCOPROTEIN; CELLS; CFTR; ASSOCIATION AB Histone deacetylase inhibitors (HDI) have exhibited some efficacy in clinical trials, but it is clear that their most effective applications have yet to be fully determined. In this study, we show that HDIs influence the expression of a common polymorphic variant of the chemotherapy drug efflux transporter ABCG2, which contributes to normal tissue protection. As one of the most frequent variants in human ABCG2, the polymorphism Q141K impairs expression, localization, and function, thereby reducing drug clearance and increasing chemotherapy toxicity. Mechanistic investigations revealed that the ABCG2 Q141K variant was fully processed but retained in the aggresome, a perinuclear structure, where misfolded proteins aggregate. In screening for compounds that could correct its expression, localization, and function, we found that the microtubule-disrupting agent colchicine could induce relocalization of the variant from the aggresome to the cell surface. More strikingly, we found that HDIs could produce a similar effect but also restore protein expression to wild-type levels, yielding a restoration of ABCG2-mediated specific drug efflux activity. Notably, HDIs did not modify aggresome structures but instead rescued newly synthesized protein and prevented aggresome targeting, suggesting that HDIs disturbed trafficking along microtubules by eliciting changes in motor protein expression. Together, these results showed how HDIs are able to restore wild-type functions of the common Q141K polymorphic isoform of ABCG2. More broadly, our findings expand the potential uses of HDIs in the clinic. Cancer Res; 72(14); 3642-51. (C)2012 AACR.

TI Proline Oxidase Promotes Tumor Cell Survival in Hypoxic Tumor Microenvironments SO CANCER RESEARCH LA English DT Article ID ACTIVATED PROTEIN-KINASE; CANCER-CELLS; GLUCOSE DEPRIVATION; BECLIN 1; AUTOPHAGY; METABOLISM; APOPTOSIS; STRESS; GROWTH; AMPK AB Proline is a readily released stress substrate that can be metabolized by proline oxidase (POX) to generate either reactive oxygen species (ROS) to induce apoptosis or autophagy or ATP during times of nutrient stress. However, the contribution of proline metabolism to tumorigenesis in hypoxic microenvironments has not been explored. In this study, we investigated the different functions of POX under hypoxia and glucose depletion. We found that hypoxia induced POX expression in cancer cells in vitro and that POX upregulation colocalized with hypoxic tissues in vivo. In addition, the combination of hypoxia and low glucose showed additive effects on POX expression. Similar to conditions of low glucose, hypoxia-mediated POX induction was dependent on AMP-activated protein kinase activation but was independent of HIF-1 alpha and HIF-2 alpha. Under low-glucose and combined low-glucose and hypoxic conditions, proline catabolized by POX was used preferentially for ATP production, whereas under hypoxia, POX mediated autophagic signaling for survival by generating ROS. Although the specific mechanism was different for hypoxia and glucose deprivation, POX consistently contributed to tumor cell survival under these conditions. Together, our findings offer new insights into the metabolic reprogramming of tumor cells present within a hostile microenvironment and suggest that proline metabolism is a potential target for cancer therapeutics.

The T-box transcription factor Brachyury has been recently characterized as a driver of EMT in human carcinoma cells. The purpose of this study was to characterize Brachyury as a potential target for lung cancer therapy. Experimental Design: The expression of Brachyury was evaluated by PCR and by immunohistochemistry in human lung tumors and adult normal tissues. Brachyury gene copy number and promoter methylation status were analyzed in tumor tissues with various levels of Brachyury expression. Lung carcinoma cells' susceptibility to T-cell lysis and EGF receptor (EGFR) kinase inhibition were also evaluated relative to the levels of Brachyury. Results: Our results showed Brachyury protein expression in 41% of primary lung carcinomas, including 48% of adenocarcinomas and 25% of squamous cell carcinomas. With the exception of normal testis and some thyroid tissues, the majority of normal tissues evaluated in this study were negative for the expression of Brachyury protein. Brachyury-specific T cells could lyse Brachyury-positive tumors and the level of Brachyury corresponded to resistance of tumor cells to EGFR kinase inhibition. Conclusion: We hypothesize that the elimination of Brachyury-positive tumor cells may be able to prevent and/or diminish tumor dissemination and the establishment of metastases. The ability of Brachyury-specific T-cell lines to lyse Brachyury-positive tumor cells, in vitro, supports the development of Brachyury-based immunotherapeutic approaches for the treatment of lung cancer.

It is unclear whether plasma free fatty acids (FFAs) influence the risk of AF in older adults. The aim of this study was to prospectively examine the association between plasma FFAs and incident AF in a prospective cohort of 4,175 men and women >= 65 years old from the Cardiovascular Health Study. Plasma concentrations of FFAs were measured 2 times during the 1992 to 1993 examination. Incident AF was ascertained based on study electrocardiographic and hospitalization records during follow-up. We used Cox regression to estimate relative risks of AF. Average age at baseline was 74.6 +/- 5.1 years. During a mean follow-up of 10.0 years, 1,041 new cases of AF occurred. Crude incidence rates of AF were 23.7, 23.3, 23.9, and 29.7 cases/1,000 person-years across consecutive quartiles of plasma FFAs. There was a positive association between plasma FFAs and risk of AF. Multivariable adjusted hazard ratios (95% confidence intervals) for incident AF were 1.00 (referent), 1.02 (0.85 to 1.21), 1.05 (0.88 to 1.26), and 1.29 (1.08 to 1.55) from the lowest to highest quartiles of FFAs, respectively. In a secondary analysis restricted to the first 5 years of follow-up, this association persisted. In conclusion, our data show an increased risk of AF with higher plasma FFAs in community-dwelling older adults. Published by Elsevier Inc.

The purpose of the present study was to assess the association between retinopathy and self-reported CVD in a subgroup of the participants in the Chronic Renal Insufficiency Cohort study. For this observational, ancillary investigation, 2,605 Chronic Renal Insufficiency Cohort participants were invited to participate in the present study, and nonmydriatic fundus photographs in both eyes were obtained for 1,936 subjects. The photographs were reviewed in a masked fashion at a central photograph reading center. The presence and severity of retinopathy (diabetic, hypertensive, or other) and vessel diameter caliber were assessed using standard protocols by trained graders who were masked to the information about the study participants. A history of self-reported CVD was obtained using a medical history questionnaire. Kidney function measurements and traditional and nontraditional risk factors for CVD were obtained from the Chronic Renal Insufficiency Cohort study. A greater severity of retinopathy was associated with a greater prevalence of any CVD, and this association persisted after adjustment for the traditional risk factors for CVD. The presence of vascular abnormalities usually associated with hypertension was also associated with increased prevalence of CVD. We found a direct relation between CVD prevalence and mean venular caliber. In conclusion, the presence of retinopathy was associated with CVD, suggesting that retinovascular pathology might indicate macrovascular disease, even after adjustment for renal dysfunction and traditional CVD risk factors. This would make the assessment of retinal morphology a valuable tool in CKD studies of CVD outcomes. (C) 2012 Elsevier Inc. All rights reserved.

Using the PubMed database, we reviewed the literature on information regarding the proper diagnosis and treatment of MEN1-associated pNET. Many cases of MEN1-associated pNET are functioning pNETs. Gastrinomas and insulinomas tend to occur frequently in the duodenum and pancreas, respectively. In addition to diagnostic imaging, the selective arterial secretagogue injection test (SASI test) is useful for localizing functioning pNET. The standard treatment is surgical resection. However, in the case of a functioning pNET, the tumor should first be accurately located using the SASI test before an appropriate surgical method is selected. In cases of a MEN1-associated non-functioning pNET that exceeds 2 cm in diameter, the incidence of distant metastasis is significantly increased, and surgery is recommended. In cases of unresectable pNET, a somatostatin analog has been shown to demonstrate antitumor effects and is considered to be a promising treatment. In addition, molecular-targeted drugs have recently been found to be effective in phase III clinical trials.

The 4-phenyl-1,2,3,6-tetrahydropyridine compounds (3i-l) have a higher affinity for 5-HT1A receptors than do the corresponding unsubstituted phenylpiperazine analogues (3e-h). Compounds 3e and 3i appear to be selective for 5-HT1A receptors over other relevant receptors and still behave as neutral antagonists. (C) 2012 Elsevier Ltd. All rights reserved.

TI Toso, a Functional IgM Receptor, Is Regulated by IL-2 in T and NK Cells SO JOURNAL OF IMMUNOLOGY LA English DT Article ID NATURAL-KILLER-CELLS; INDUCED APOPTOSIS; DEATH; FAS; CYTOTOXICITY; SURFACE; ROLES; INTERLEUKIN-2; LYMPHOCYTES; HOMEOSTASIS AB We find that the cell surface receptor Toso is dramatically downregulated by in vitro stimulation of human Tand NK cells with IL-2 in a STAT5-dependent manner. The fact that IL-2 is known to prime NK and T cells for Fas/TNF-mediated activation-induced cell death (AICD) fits nicely with the original and recent descriptions of Toso as an inhibitor of Fas/TNF-induced apoptosis. In support of this possibility, effector memory T cells express markedly lower levels of Toso than those of naive T cells, indicating that activation in vivo correlates with the downregulation of Toso. Moreover, in vitro activation of memory T cells through TCR dramatically downregulates Toso expression compared with that of naive CD4 T cells. However, overexpression of Toso in human NK cells and Jurkat T cells does not inhibit Fas-mediated apoptosis, and, in agreement with other recent reports, Toso clearly functions as an IgM receptor. Unlike CD16, Toso expression by NK cells does not convey cytotoxic potential, but its ligation does trigger intracellular signaling in NK cells. In summary, our data indicate that Toso is a functional IgM receptor that is capable of activating signaling molecules, is regulated by IL-2, and is not inherently an antiapoptotic molecule.

TI Increased Frequency of Suppressive Regulatory T Cells and T Cell-Mediated Antigen Loss Results in Murine Melanoma Recurrence SO JOURNAL OF IMMUNOLOGY LA English DT Article ID ANTITUMOR IMMUNE-RESPONSES; LARGE ESTABLISHED MELANOMA; LYMPHOPENIC HOSTS; TUMOR-IMMUNITY; HOMEOSTATIC PROLIFERATION; CANCER; SURVEILLANCE; LYMPHOCYTES; CARCINOMA; IMMUNOTHERAPY AB Therapeutic treatment of large established tumors using immunotherapy has yielded few promising results. We investigated whether adoptive transfer of tumor-specific CD8(+) T cells, together with tumor-specific CD4(+) T cells, would mediate regression of large established B16BL6-D5 melanomas in lymphopenic Rag1(-/-) recipients devoid of regulatory T cells. The combined adoptive transfer of subtherapeutic doses of both TRP1-specific TCR transgenic Rag1(-/-) CD4(+) T cells and gp100-specific TCR transgenic Rag1(-/-) CD8(+) T cells into lymphopenic recipients, who received vaccination, led to regression of large (100-400 mm 2) melanomas. The same treatment strategy was ineffective in lymphoreplete wild-type mice. Twenty-five percent of mice (15/59) had tumors recur (15-180 d postregression). Recurrent tumors were depigmented and had decreased expression of gp100, the epitope targeted by the CD8(+) T cells. Mice with recurrent melanoma had increased CD4(+) Foxp3(+) TRP1-specific T cells compared with mice that did not show evidence of disease. Importantly, splenocytes from mice with recurrent tumor were able to suppress the in vivo therapeutic efficacy of splenocytes from tumor-free mice. These data demonstrate that large established tumors can be treated by a combination of tumor-specific CD8(+) and CD4(+) T cells. Additionally, recurrent tumors exhibited decreased Ag expression, which was accompanied by conversion of the therapeutic tumor-specific CD4(+) T cell population to a Foxp3(+) CD4(+) regulatory T cell population.

The replacement of thymidines in the TGT loop by U and FU results in an increased stability of the antiparallel quadruplex structure described for the TBA while the presence of NT residues in the same positions destabilizes the antiparallel structure. The substitution of the thymidines in the TT loops for U, FU and NT induce a destabilization of the antiparallel quadruplex, indicating the crucial role of these positions. NMR studies on TBAs modified with uridines at the TGT loop also confirm the presence of the antiparallel quadruplex structure. Nevertheless, replacement of two Ts in the TT loops by uridine gives a more complex scenario in which the antiparallel quadruplex structure is present along with other partially unfolded species or aggregates.

Previously, we studied the mechanism of HPPK action, synthesized bisubstrate analog inhibitors by linking 6-hydroxymethylpterin to adenosine through phosphate groups, and developed a new generation of bisubstrate inhibitors by replacing the phosphate bridge with a piperidine-containing linkage. To further improve linker properties, we have synthesized a new compound, characterized its protein binding/inhibiting properties, and determined its structure in complex with HPPK. Surprisingly, this inhibitor exhibits a new binding mode in that the adenine base is flipped when compared to previously reported structures. Furthermore, the side chain of amino acid residue E77 is involved in protein-inhibitor interaction, forming hydrogen bonds with both 2' and 3' hydroxyl groups of the ribose moiety. Residue E77 is conserved among HPPK sequences, but interacts only indirectly with the bound MgATP via water molecules. Never observed before, the E77-ribose interaction is compatible only with the new inhibitor-binding mode. Therefore, this compound represents a new direction for further development.

Studies suggest that low-dose, continuous exposure is more efficacious than intermittent, high doses. The authors performed a phase 2 study of recombinant interferon a-2b with monomethoxy polyethylene glycol (PEG-Intron (R)) in children with diffuse intrinsic pontine glioma (DIPG), a population with dismal survival despite decades of clinical investigation. The primary objective was to compare 2-year survival with a historic cohort that received radiation therapy alone. METHODS: Patients received weekly subcutaneous PEG-Intron (R) at a dose of 0.3 mu g/kg beginning 2 to 10 weeks after the completion of radiation therapy until they developed disease progression. Patients were evaluated clinically and radiographically at regular intervals. Serum and urine were assayed for biomarkers before each cycle. Quality-of-life (QOL) evaluations were administered at baseline and before every other cycle of therapy to the parents of patients ages 6 to 18 years. RESULTS: Thirty-two patients (median age, 5.3 years; range, 1.8-14.8 years) were enrolled and received a median of 7 cycles of therapy (range, from 1 cycle to =70 cycles). PEG-Intron (R) was well tolerated, and no decrease in QOL scores was noted in the subset of patients tested. The 2-year survival rate was 14%, which was not significantly improved compared with the historic cohort. However, the median time to progression was 7.8 months, which compared favorably with recent trials reporting a time to progression of 5 months in a similar population. CONCLUSIONS: Although low-dose PEG-Intron (R) therapy did not significantly improve 2-year survival in children with DIPG compared with an historic control population, it did delay the time to progression.

This study examined the relationship between both individual and area-level SES and CRC incidence, overall and by tumor location. METHODS: Data were obtained from the ongoing prospective National Institutes of Health-AARP Diet and Health Study of persons (50-71 years old) who resided in 6 US states and 2 metropolitan areas at baseline in 1995-1996. Incident CRCs were ascertained from tumor registries through December 2006. SES was measured by self-reported education and census-tract socioeconomic deprivation. Baseline and follow-up questionnaires collected detailed information on individual-level CRC risk factors including family history and health behaviors. RESULTS: Among 506,488 participants analyzed, 7676 were diagnosed with primary invasive colorectal adenocarcinomas: 46.6% in the right colon, 26.7% in the left colon, and 25.9% in the rectum. The overall incidence of CRC was significantly higher among people who had low educational level or lived in low-SES neighborhoods, relative to respective highest-SES groups, even after accounting for other risk factors. These associations were stronger in the rectum than in left or right colon. In the right colon, there were no significant SES differences by either SES measure after accounting for covariates. CONCLUSIONS: SES, assessed by either individual-level education or neighborhood measures, was associated with risk of CRC even after accounting for other risk factors. The relationship between SES and CRC was strongest in the rectum and weakest in the right colon. Cancer 2012;36363644. (C) 2012 American Cancer Society.

TI Effects of Recombinant Human Interleukin 7 on T-Cell Recovery and Thymic Output in HIV-Infected Patients Receiving Antiretroviral Therapy: Results of a Phase I/IIa Randomized, Placebo-Controlled, Multicenter Study SO CLINICAL INFECTIOUS DISEASES LA English DT Article ID IN-VIVO EXPANSION; RHESUS MACAQUES; IL-7; REPERTOIRE; IMMUNODEFICIENCY; TRANSPLANTATION; PROLIFERATION; HOMEOSTASIS; ACTIVATION; DIVERSITY AB Background. The immune deficiency of human immunodeficiency virus (HIV) infection is not fully corrected with ARV therapy. Interleukin-7 (IL-7) can boost CD4 T-cell counts, but optimal dosing and mechanisms of cellular increases need to be defined. Methods. We performed a randomized placebo-controlled dose escalation (10, 20 and 30 mu g/kg) trial of 3 weekly doses of recombinant human IL-7 (rhIL-7) in ARV-treated HIV-infected persons with CD4 T-cell counts between 101 and 400 cells/mu L and plasma HIV levels <50 copies/mL. Toxicity, activity and the impact of rhIL-7 on immune reconstitution were monitored. Results. Doses of rhIL-7 up to 20 mu g/kg were well tolerated. CD4 increases of predominantly naive and central memory T cells were brisk (averaging 323 cells/mu L at 12 weeks) and durable (up to 1 year). Increased cell cycling and transient increased bcl-2 expression were noted. Expanded cells did not have the characteristics of regulatory or activated T cells. Transient low-level HIV viremia was seen in 6 of 26 treated patients; modest increases in total levels of intracellular HIV DNA were proportional to CD4 T-cell expansions. IL-7 seemed to increase thymic output and tended to improve the T-cell receptor (TCR) repertoire in persons with low TCR diversity. Conclusions. Three weekly doses of rhIL-7 at 20 mu g/kg are well tolerated and lead to a dose-dependent CD4 T-cell increase and the broadening of TCR diversity in some subjects. These data suggest that this rhIL-7 dose could be advanced in future rhIL-7 clinical studies. C1 [Levy, Y.; Lelievre, J. D.] Hop Henri Mondor, INSERM, U955, F-94010 Creteil, France.

TI The Rates of HIV Superinfection and Primary HIV Incidence in a General Population in Rakai, Uganda SO JOURNAL OF INFECTIOUS DISEASES LA English DT Article ID IMMUNODEFICIENCY-VIRUS TYPE-1; DUAL INFECTION; DISEASE PROGRESSION; AMSTERDAM COHORT; SEXUAL-BEHAVIOR; HOMOSEXUAL-MEN; REGION; RISK; FREQUENCY; RESPONSES AB Background. Human immunodeficiency virus (HIV) superinfection has been documented in high-risk individuals; however, the rate of superinfection among HIV-infected individuals within a general population remains unknown. Methods. A novel next-generation ultra-deep sequencing technique was utilized to determine the rate of HIV superinfection in a heterosexual population by examining two regions of the viral genome in longitudinal samples from recent HIV seroconverters (n = 149) in Rakai District, Uganda. Results. The rate of superinfection was 1.44 per 100 person years (PYs) (95% confidence interval [CI],.4-2.5) and consisted of both inter-and intrasubtype superinfections. This was compared to primary HIV incidence in 20 220 initially HIV-negative individuals in the general population in Rakai (1.15 per 100 PYs; 95% CI, 1.1-1.2; P = .26). Propensity score matching (PS) was used to control for differences in sociodemographic and behavioral characteristics between the HIV-positive individuals at risk for superinfection and the HIV-negative population at baseline and follow-up. After PS matching, the estimated rate of primary incidence was 3.28 per 100 PYs (95% CI, 2.0-5.3; P = .07) controlling for baseline differences and 2.51 per 100 PYs (95% CI, 1.5-4.3; P = .24) controlling for follow-up differences. Conclusions. This suggests that the rate of HIV superinfection in a general population is substantial, which could have a significant impact on future public health and HIV vaccine strategies.

In this paper we introduce a novel feature called minutia handedness to deal with this problem. First, reference points are detected and additional checking conditions are added to ensure that genuine and accurate reference points can be found. Second, minutia handedness is defined for each minutia according to the bending degree of its associated ridges or the position of the reference points. There are three types of minutiae handedness: right-handed, left-handed and non-handed. Finally, the matching rules between different types of minutiae handedness are set up. The proposed method is tested on eight data sets of FVC2002 (2002) and FVC2004 (2004). The experimental results indicate that the performance of a convectional fingerprint recognition algorithm can be improved by incorporating minutia handedness with a small increment of template size.

We describe a new technique using HPLC with coulometric electrochemical detection for ascorbate measurement in RBCs of humans, wild-type mice, and mice unable to synthesize ascorbate. Exogenously added ascorbate was fully recovered even when endogenous RBC ascorbate was below the detection threshold (25 nM). Twenty microliters of whole blood or 10 mu l of packed RBCs was sufficient for assay. RBC ascorbate was stable for 24 h from whole-blood samples at 4 degrees C. Processed, stored samples were stable for >1 month at -80 degrees C. Unlike other tissues, ascorbate concentrations in human and mouse RBCs were linear in relation to plasma concentrations (R = 0.8 and 0.9, respectively). In healthy humans, RBC ascorbate concentrations were 9-57 mu M, corresponding to ascorbate plasma concentrations of 15-90 mu M. Mouse data were similar. In human blood stored as if for transfusion, initial RBC ascorbate concentrations varied approximately sevenfold and decreased 50% after 6 weeks of storage under clinical conditions. With this assay, it becomes possible for the first time to characterize ascorbate function in relation to endogenous concentrations in RBCs. Published by Elsevier Inc.

TI Role of Early Postradiation Magnetic Resonance Imaging Scans in Children With Diffuse Intrinsic Pontine Glioma SO INTERNATIONAL JOURNAL OF RADIATION ONCOLOGY BIOLOGY PHYSICS LA English DT Article DE Pontine glioma; Radiotherapy; MRI; Optimal timing ID BRAIN-STEM GLIOMA; PEDIATRIC-ONCOLOGY-GROUP; HYPERFRACTIONATED RADIOTHERAPY; TUMORS; TRIAL AB Purpose: To determine optimal timing of assessing postradiation radiographic response on magnetic resonance imaging (MRI) scans in pediatric patients with diffuse intrinsic pontine glioma (DIPG). Methods and Materials: Patients were treated on a prospective study at the National Cancer Institute (Protocol #06-C-0219) evaluating the effects of radiotherapy (RT). Standard RT was administered in standard fractionation over 6 weeks. Postradiation MRI scans were performed at 2 and 6-8 weeks. Results: Eleven patients with DIPG were evaluated. Median age was 6 years (range, 4-13 years). Patients were treated with external-beam RT to 55.8Gy(n = 10) or54Gy(n = 1), with a gross tumor volume to planning target volume expansion of 1.8-2.0 cm. All patients received prescribed dose and underwent posttreatment MRI scans at 2 and 6-8 weeks. Pretreatment imaging revealed compression of fourth ventricle (n = 11); basilar artery encasement (n = 9); tumor extension outside the pons (n = 11); and tumor hemorrhage (n = 2). At the 2-week scan, basilar artery encasement improved in 7 of 9 patients, and extent of tumor was reduced in 5 of 11 patients. Fourth ventricle compression improved in 6 of 11 patients but worsened in 3 of 11 patients. Presumed necrosis was observed in 5 of 11 patients at 2 weeks and in 1 additional patient at 6-8 weeks. There was no significant difference in mean anteroposterior and transverse diameters of tumor between the 2- and 6-8-week time points. Six of 11 patients had increasing ventricular size, with no evidence of obstruction. Conclusions: There is no significant difference in tumor size of DIPG patients who have received standard RT when measured at 2 weeks vs. 6-8 weeks after RT. The majority of patients had the largest change in tumor size at the 2-week post-RT scan, with evolving changes documented on the 6-8-week scan. Six of 11 patients had progressive ventriculomegaly without obstruction, suggestive of communicating hydrocephalus. To the best of our knowledge, this is the first documentation of this phenomenon in this cohort of patients. (C) 2012 Elsevier Inc.

TI Pharmacological Protection From Radiation +/- Cisplatin-Induced Oral Mucositis SO INTERNATIONAL JOURNAL OF RADIATION ONCOLOGY BIOLOGY PHYSICS LA English DT Article DE Chemoradiation; Side effects; Oral mucositis; Tempol; D-methionine ID NECK-CANCER; TEMPOL; HEAD; PREVENTION; RADIOTHERAPY; METHIONINE; GLANDS; TUMOR; MODEL AB Purpose: To evaluate if two pharmacological agents, Tempol and D-methionine (D-met), are able to prevent oral mucositis in mice after exposure to ionizing radiation +/- cisplatin. Methods and Materials: Female C3H mice, similar to 8 weeks old, were irradiated with five fractionated doses +/- cisplatin to induce oral mucositis (lingual ulcers). Just before irradiation and chemotherapy, mice were treated, either alone or in combination, with different doses of Tempol (by intraperitoneal [ip] injection or topically, as an oral gel) and D-met (by gavage). Thereafter, mice were sacrificed and tongues were harvested and stained with a solution of Toluidine Blue. Ulcer size and tongue epithelial thickness were measured. Results: Significant lingual ulcers resulted from 5 x 8 Gy radiation fractions, which were enhanced with cisplatin treatment. D-met provided stereospecific partial protection from lingual ulceration after radiation. Tempol, via both routes of administration, provided nearly complete protection from lingual ulceration. D-met plus a suboptimal ip dose of Tempol also provided complete protection. Conclusions: Two fairly simple pharmacological treatments were able to markedly reduce chemoradiation-induced oral mucositis in mice. This proof of concept study suggests that Tempol, alone or in combination with D-met, may be a useful and convenient way to prevent the severe oral mucositis that results from head-and-neck cancer therapy.

Genetic experiments suggested that theta subunit stabilizes the intrinsically labile epsilon subunit and, furthermore, that theta might affect the cellular amounts of Pol III core and HE. Here, we provide biochemical evidence supporting this model by analyzing the amounts of the relevant proteins. First, we show that a Delta holE strain (lacking theta subunit) displays reduced amounts of free epsilon. We also demonstrate the existence of a dimer of epsilon, which may be involved in the stabilization of the protein. Second, theta, when overexpressed, dissociates the epsilon dimer and significantly increases the amount of Pol III core. The stability oft epsilon also depends on cellular chaperones, including DnaK. Here, we report that: (i) temperature shift-up of Delta dnaK strains leads to rapid depletion of E, and (ii) overproduction of theta overcomes both the depletion of epsilon, and the temperature sensitivity of the strain. Overall, our data suggest that epsilon is a critical factor in the assembly of Pol III core, and that this is role is strongly influenced by the theta subunit through its prevention oft epsilon degradation.

Herein, we have examined if IL-13 regulates invasion and metastasis of ovarian cancer through IL-13Ra2 in vitro and in vivo in animal models of human ovarian cancer. We tested cell invasion and protease activity in IL-13Ra2-overexpressing and IL-13Ra2-negative ovarian tumor cell lines. IL-13 treatment significantly augmented both cell invasion and enzyme activities in only IL-13Ra2-positive cells but not in IL-13Ra2-negative cells in vitro. Mechanistically, IL-13 enhanced ERK1/2, AP-1 and MMP activities only in IL-13Ra2-positive cells but not in IL-13Ra2-negative cells. In contrast, other signaling pathways such as IRS1/2, PI3K and AKT do not seem to be involved in IL-13 induced signaling in ovarian cancer cell lines. Highly specific inhibitors for MMP and AP-1 efficiently inhibited both invasion and protease activities without impacting the basal level invasion and protease activities in vitro. In orthotopic animal model of human ovarian cancer, IL-13Ra2-positive tumors metastasized to lymph nodes and peritoneum earlier than IL-13Ra2-negative tumors. Interestingly, the IL-13Ra2-positive tumor bearing mice died earlier than mice with IL-13Ra2-negative tumor. Intraperitoneal injection of IL-13 further shortened survival of IL-13Ra2-positive tumor bearing mice compared to IL-13Ra2-negative tumor mice. IL-13Ra2-positive tumors and lymph node metastasis expressed higher levels of MMPs and higher ERK1/2 activation compared to IL-13Ra2-negative tumors. Taken together, IL-13Ra2 is involved in cancer metastasis through activation of ERK/AP-1 and that targeting IL-13Ra2 might not only directly kill primary tumors but also prevent cancer metastasis.

Whole genome transcriptional analysis clearly indicate that regression of melanoma metastases is due to an acute immune rejection mediated by the upregulation of genes involved in antigen presentation and interferon mediated response (STAT-1/IRF-1) in all the regressing metastases from both patients. In contrast, progressing metastases showed low transcription levels of genes involved in these pathways. Histological analysis showed T cells and HLA-DR positive infiltrating cells in the regressing but not in the progressing metastases. Quantitative expression analysis of HLA-A,B and C genes on microdisected tumoral regions indicate higher HLA expression in regressing than in progressing metastases. The molecular signature obtained in melanoma rejection appeared to be similar to that observed in other forms of immune-mediated tissue-specific rejection such as allograft, pathogen clearance, graft versus host or autoimmune disease, supporting the immunological constant of rejection. We favor the idea that the major factor determining the success or failure of immunotherapy is the nature of HLA Class I alterations in tumor cells and not the type of immunotherapy used. If the molecular alteration is reversible by the immunotherapy, the HLA expression will be upregulated and the lesion will be recognized and rejected. In contrast, if the defect is structural the MHC Class I expression will remain unchanged and the lesion will progress.

TI Coffee intake and breast cancer risk in the NIH-AARP diet and health study cohort SO INTERNATIONAL JOURNAL OF CANCER LA English DT Article DE breast neoplasms; coffee; caffeine; cohort studies; epidemiology ID CYCLIC-NUCLEOTIDES; WOMENS HEALTH; CAFFEINE; ASSOCIATION; CONSUMPTION; TEA; PREMENOPAUSAL; INFLAMMATION; DISEASE; MODEL AB There are several biologic mechanisms whereby coffee might reduce breast cancer risk. Caffeine and caffeic acid, major coffee constituents, have been shown to suppress mammary tumor formation in animal models and to inhibit DNA methylation in human breast cancer cells, respectively. Coffee may also reduce risk through decreasing inflammation and influencing estrogen metabolism. However, epidemiologic studies have been inconsistent and few studies have examined the association by estrogen and progesterone receptor (ER/PR) status. We evaluated coffee intake for its effect on incident breast cancer in the National Institutes of Health-AARP Diet and Health Study cohort, which included 198,404 women aged 5071 with no history of cancer, who in 19951996 completed a questionnaire capturing usual coffee intake over the past year. State cancer registry and mortality index linkage identified 9,915 primary incident breast carcinomas through December 2006; available information on hormone receptor (HR) status identified 2,051 ER+/PR+ and 453 ER-/PR- cancers. In multivariable proportional hazards models, coffee intake was not associated with breast cancer risk (p-value for trend = 0.38; relative risk = 0.98, 95% confidence interval: 0.911.07, for four or more cups per day as compared to women who never drank coffee), and results did not vary by body mass index or history of benign breast biopsy (p-value for interaction > 0.10). We found no evidence of a relationship with either caffeinated or decaffeinated coffee. Null findings persisted for risk of both HR-positive and -negative breast cancers. These findings from a large prospective cohort do not support a role of coffee intake in breast carcinogenesis.

TI Survival outcomes in endometrial cancer patients are associated with CXCL12 and estrogen receptor expression SO INTERNATIONAL JOURNAL OF CANCER LA English DT Article DE clear cell; papillary serous; prognostic biomarkers; chemokines; metastasis ID CLEAR-CELL CARCINOMAS; CHEMOKINE RECEPTORS; BREAST-CANCER; ER-ALPHA; FACTOR-I; METASTASIS; CXCR4; ADENOCARCINOMA; AXIS; INVOLVEMENT AB CXCL12 is a chemotactic cytokine that has pro-metastatic functions in several malignancies through interactions with its receptor, CXCR4. CXCL12 is an estrogen-regulated gene, and notably, estrogen is a major risk factor for endometrial cancer (EC) development. As few studies examine concurrent CXCL12, CXCR4, and estrogen receptor (ER) expression in EC patients, we examined this pathway in 199 EC patients with data from the University of Pittsburgh Medical Center Cancer Registry. Immunohistochemistry (IHC) was used to detect CXCR4, CXCL12 and ER protein expression. As CXCR4 expression was positive in all cases, this investigation focused on associations between CXCL12 and ER expression, clinicopathologic factors and survival outcomes using chi-square tests, Kaplan-Meier graphs, and log-rank tests. CXCL12 expression was negative in 63 cases (32%) and positive in 136 cases (68%). Negative CXCL12 expression was borderline significantly associated with metastasis (?2 p = 0.07). ER expression was negative in 75 cases (38%) and positive in 124 cases (62%). Positive ER expression was significantly associated with low grade and early stage tumors (?2 p < 0.001). CXCL12 and ER were not significantly associated (?2 p = 0.11). Positive CXCL12 expression was associated with longer overall survival (OS) (log-rank p = 0.006) and longer recurrence-free survival (RFS) (log-rank p = 0.01) in ER negative patients, but not in ER positive patients. We identified a unique molecular signature associated with better OS and RFS in EC patients. In addition to pathological characteristics of the tumor, expression of CXCL12 and ER may be clinically useful for assigning adjuvant treatment to EC cases.

TI Serum IGF1, IGF2 and IGFBP3 and risk of advanced colorectal adenoma SO INTERNATIONAL JOURNAL OF CANCER LA English DT Article DE colorectal adenoma; insulin-like growth factor ID GROWTH-FACTOR-I; CANCER SCREENING TRIAL; BINDING PROTEIN-3; FACTOR (IGF)-I; CIRCADIAN-RHYTHMS; BREAST-CANCER; FACTOR EGF; C-PEPTIDE; INSULIN; RECEPTOR AB The insulin-like growth factor (IGF) signaling pathway is involved in cell proliferation and differentiation. Elevated serum IGF1 levels have been associated with increased colorectal cancer risk; however, studies of this association with colorectal adenoma are inconclusive. We examined serum IGF1, IGF2 and IGFBP3 levels in relation to risk of advanced colorectal adenoma in a case-control study within the prostate, lung, colorectal and ovarian cancer screening trial. A total of 764 advanced, left-sided colorectal adenoma cases and 775 controls frequency-matched on gender and ethnicity, without evidence of a left-sided polyp on sigmoidoscopy were included in the current study. Serum levels of IGF1, IGF2 and IGFBP3 were measured using an enzyme linked immunosorbent assay in serum samples collected at baseline. Logistic regression was used to estimate the odds ratios (OR) and 95% confidence intervals (CI) for the associations adjusting for age, race, sex, year of blood draw, body mass index, smoking and education. Higher IGF1 levels were associated with increased adenoma risk: ORs = 1.58 (95% CI = 1.162.16), 1.42 (95% CI = 1.041.93), and 1.80 (95% CI = 1.302.47) for the second, third and fourth quartiles, respectively (ptrend = 0.002). Elevated IGF2 levels were also associated with increased adenoma risk (OR = 1.43, 95% CI = 1.051.96 for the fourth vs. first quartile, ptrend = 0.02), but the association was no longer significant after adjustment for IGF1 (ptrend = 0.28). IGFBP3 levels were not associated with adenoma risk. Our analysis showed a significant positive association between circulating IGF1 levels and risk of advanced colorectal adenoma, suggesting that IGF1 is associated with the pivotal precursor to colorectal cancer.

Michal TI Basal cell carcinoma and anthropometric factors in the U.S. radiologic technologists cohort study SO INTERNATIONAL JOURNAL OF CANCER LA English DT Article DE basal cell carcinoma; weight; height; body mass index; skin cancer ID CANCER-RISK; UNITED-STATES; SKIN; HEIGHT; ESTROGEN; MEN AB Basal cell carcinoma (BCC) is the most common cancer in Caucasian populations. Although several risk factors are well-established, including ultraviolet radiation (UVR) sensitivity and exposure, few studies have examined anthropometric measures and BCC. Using Cox proportional hazards regression analysis, we prospectively investigated the relationship between height, weight and body mass index (BMI) and BCC in 58,213 Caucasian participants (11,631 men and 46,582 women) from the United States Radiological Technologists cohort. This analysis was limited to participants who were cancer-free at baseline. The baseline questionnaire provided self-reported anthropometric factors and the subsequent questionnaire collected skin cancer susceptibility factors, lifetime UVR exposure derived from residential and personal UVR exposure (time outdoors) and health outcomes. During 509,465 person-years of follow-up, we identified 2,291 BCC cases (486 men; 1,805 women). BCC risk increased with increasing height, and decreased with increasing weight and BMI in both sexes, even after adjusting for UVR susceptibility factors and exposures. For BMI categories: <25 (reference); 25<30; 30<35 and =35 kg m-2, multivariate hazard ratios (HR) in women were: 1.00; 0.74 (95% CI = 0.660.83); 0.67 (0.560.81) and 0.57 (0.440.74), respectively, p-trend =0.0001. Risks were similar in men. The inverse association between BMI and BCC was unaffected by controlling for sun-related exposures. Nevertheless, it may at least partly reflect residual UVR confounding. Further research with more detailed sun exposure data, including clothing patterns, would help clarify the relationship between BMI and BCC.

By preventing high-risk pregnancies, especially in women of high parities, and those that would have ended in unsafe abortion, increased contraceptive use has reduced the maternal mortality ratio-the risk of maternal death per 100 000 livebirths-by about 26% in little more than a decade. A further 30% of maternal deaths could be avoided by fulfilment of unmet need for contraception. The benefits of modern contraceptives to women's health, including non-contraceptive benefits of specific methods, outweigh the risks. Contraception can also improve perinatal outcomes and child survival, mainly by lengthening interpregnancy intervals. In developing countries, the risk of prematurity and low birthweight doubles when conception occurs within 6 months of a previous birth, and children born within 2 years of an elder sibling are 60% more likely to die in infancy than are those born more than 2 years after their sibling.

TI Exploring the interaction between SNP genotype and postmenopausal hormone therapy effects on stroke risk SO GENOME MEDICINE LA English DT Article ID ESTROGEN PLUS PROGESTIN; RANDOMIZED CONTROLLED-TRIAL; GENOME-WIDE ASSOCIATION; INVASIVE BREAST-CANCER; FAT DIETARY PATTERN; ISCHEMIC-STROKE; ATRIAL-FIBRILLATION; EQUINE ESTROGEN; FGFR2 GENE; WOMEN AB Background: Genome-wide association studies have identified several genomic regions that are associated with stroke risk, but these provide an explanation for only a small fraction of familial stroke aggregation. Genotype by environment interactions may contribute further to such an explanation. The Women's Health Initiative (WHI) clinical trial found increased stroke risk with postmenopausal hormone therapy (HT) and provides an efficient setting for evaluating genotype-HT interaction on stroke risk. Methods: We examined HT by genotype interactions for 392 SNPs selected from candidate gene studies, and 2,371 SNPs associated with changes in blood protein concentrations after hormone therapy, in analyses that included 2,045 postmenopausal women who developed stroke during WHI clinical trial and observational study follow-up and one-to-one matched controls. A two-stage procedure was implemented where SNPs passing the first stage screening based on marginal association with stroke risk were tested in the second stage for interaction with HT using case-only analysis. Results: The two-stage procedure identified two SNPs, rs2154299 and rs12194855, in the coagulation factor XIII subunit A (F13A1) region and two SNPs, rs630431 and rs560892, in the proprotein convertase subtilisin kexin 9 (PCSK9) region, with an estimated false discovery rate <0.05 based on interaction tests. Further analyses showed significant stroke risk interaction between these F13A1 SNPs and estrogen plus progestin (E+P) treatment for ischemic stroke and for ischemic and hemorrhagic stroke combined, and suggested interactions between PCSK9 SNPs with either E+P or estrogen-alone treatment. Conclusions: Genotype by environment interaction information may help to define genomic regions relevant to stroke risk. Two-stage analysis among postmenopausal women generates novel hypotheses concerning the F13A1 and PCSK9 genomic regions and the effects of hormonal exposures on postmenopausal stroke risk for subsequent independent validation.

TI The Pleckstrin Homology (PH) Domain of the Arf Exchange Factor Brag2 Is an Allosteric Binding Site SO JOURNAL OF BIOLOGICAL CHEMISTRY LA English DT Article ID ADP-RIBOSYLATION FACTOR; GUANINE-NUCLEOTIDE-EXCHANGE; AMINO-TERMINUS; ACTIN CYTOSKELETON; MYRISTOYLATED ARF1; KINETIC MECHANISM; STRUCTURAL BASIS; CELL-ADHESION; FACTOR ARNO; G-PROTEINS AB Brag2, a Sec7 domain (sec7d)-containing guanine nucleotide exchange factor, regulates cell adhesion and tumor cell invasion. Brag2 catalyzes nucleotide exchange, converting Arf.GDP to Arf.GTP. Brag2 contains a pleckstrin homology (PH) domain, and its nucleotide exchange activity is stimulated by phosphatidylinositol 4,5-bisphosphate (PIP2). Here we determined kinetic parameters for Brag2 and examined the basis for regulation by phosphoinositides. Using myristoylated Arf1.GDP as a substrate, the k(cat) was 1.8 +/- 0.1/s as determined by single turnover kinetics, and the K-m was 0.20 +/- 0.07 mu M as determined by substrate saturation kinetics. PIP2 decreased the K-m and increased the k(cat) of the reaction. The effect of PIP2 required the PH domain of Brag2 and the N terminus of Arf and was largely independent of Arf myristoylation. Structural analysis indicated that the linker between the sec7d and the PH domain in Brag2 may directly contact Arf. In support, we found that a Brag2 fragment containing the sec7d and the linker was more active than sec7d alone. We conclude that Brag2 is allosterically regulated by PIP2 binding to the PH domain and that activity depends on the interdomain linker. Thus, the PH domain and the interdomain linker of Brag2 may be targets for selectively regulating the activity of Brag2.

TI Protein Kinase C alpha and Src Kinase Support Human Prostate-distributed Dihydrotestosterone-metabolizing UDP-glucuronosyltransferase 2B15 Activity SO JOURNAL OF BIOLOGICAL CHEMISTRY LA English DT Article ID REGULATED PHOSPHORYLATION; EXPRESSION; CANCER; CELLS; ANDROGEN; EPITHELIUM; ESTROGENS; ENZYMES; DELTA; 5-ALPHA-REDUCTASE AB Because human prostate-distributed UDP-glucuronosyl-transferase (UGT) 2B15 metabolizes 5 alpha-dihydrotestosterone (DHT) and 3 alpha-androstane-5 alpha,17 beta-diolmetabolite, we sought to determine whether 2B15 requires regulated phosphorylation similar to UGTs already analyzed. Reversible down-regulation of 2B15-transfected COS-1 cells following curcumin treatment and irreversible inhibition by calphostin C, bisindolylmaleimide, or rottlerin treatment versus activation by phorbol 12-myristate 13-acetate indicated that 2B15 undergoes PKC phosphorylation. Mutation of three predicted PKC and two tyrosine kinase sites in 2B15 caused 70-100 and 80-90% inactivation, respectively. Anti-UGT-1168 antibody trapped 2B15-His-containing co-immunoprecipitates of PKC alpha in 130-140- and >150-kDa complexes by gradient SDS-PAGE analysis. Complexes bound to WT 2B15-His remained intact during electrophoresis, whereas 2B15-His mutants at phosphorylation sites differentially dissociated. PKC alpha siRNA treatment inactivated >50% of COS-1 cell-expressed 2B15. In contrast, treatment of 2B15-transfected COS-1 cells with the Src-specific activator 1,25-dihydroxyvitamin D-3 enhanced activity; treatment with the Src-specific PP2 inhibitor or Src siRNA inhibited >50% of the activity. Solubilized 2B15-His-transfected Src-free fibroblasts subjected to in vitro [gamma-P-33]ATP-dependent phosphorylation by PKC alpha and/or Src, affinity purification, and SDS gel analysis revealed 2-fold more radiolabeling of 55-58-kDa 2B15-His by PKC alpha than by Src; labeling was additive for combined kinases. Collectively, the evidence indicates that 2B15 requires regulated phosphorylation by both PKC alpha and Src, which is consistent with the complexity of synthesis and metabolism of its major substrate, DHT. Whether basal cells import or synthesize testosterone for transport to luminal cells for reduction to DHT by 5 alpha-steroid reductase 2, comparatively low-activity luminal cell 2B15 undergoes a complex pattern of regulated phosphorylation necessary to maintain homeostatic DHT levels to support occupation of the androgen receptor for prostate-specific functions.

TI Annexin A1 Interaction with the FPR2/ALX Receptor IDENTIFICATION OF DISTINCT DOMAINS AND DOWNSTREAM ASSOCIATED SIGNALING SO JOURNAL OF BIOLOGICAL CHEMISTRY LA English DT Article ID FORMYL-PEPTIDE RECEPTOR; FUNCTIONAL DOMAINS; HUMAN NEUTROPHILS; INFLAMMATION; RESPONSES; AGONIST; LIGAND; FPR; ACTIVATION; PATHWAYS AB Understanding how proresolving agonists selectively activate FPR2/ALX is a crucial step in the clarification of proresolution molecular networks that can be harnessed for the design of novel therapeutics for inflammatory disease. FPR2/ALX, a G protein-coupled receptor belonging to the formyl peptide receptor (FPR) family, conveys the biological functions of a variety of ligands, including the proresolution mediators annexin A1 (AnxA1) and lipoxin A(4), as well as the activating and proinflammatory protein serum amyloid A. FPR2/ALX is the focus of intense screening for novel anti-inflammatory therapeutics, and the small molecule compound 43 was identified as a receptor ligand. Here, we used chimeric FPR1 and FPR2/ALX clones (stably transfected in HEK293 cells) to identify the N-terminal region and extracellular loop II as the FPR2/ALX domain required for AnxA1-mediated signaling. Genomic responses were also assessed with domain-specific effects emerging, so the N-terminal region is required for AnxA1 induction of JAG1 and JAM3, whereas it is dispensable for modulation of SGPP2. By comparison, serum amyloid A non-genomic responses were reliant on extracellular loops I and II, whereas the small molecule compound 43 activated extracellular loop I with downstream signaling dependent on transmembrane region II. In desensitization experiments, the N-terminal region was dispensable for AnxA1-induced FPR2/ALX down-regulation in both the homologous and heterologous desensitization modes.

TI Abcb11 Deficiency Induces Cholestasis Coupled to Impaired beta-Fatty Acid Oxidation in Mice SO JOURNAL OF BIOLOGICAL CHEMISTRY LA English DT Article ID SALT EXPORT PUMP; FAMILIAL INTRAHEPATIC CHOLESTASIS; FARNESOID-X-RECEPTOR; P-GLYCOPROTEIN; KNOCKOUT MICE; BILE-ACIDS; MOLECULAR-MECHANISMS; NUCLEAR RECEPTOR; EXPRESSION; LIVER AB The bile salt export pump (BSEP) is an ATP-binding cassette transporter that serves as the primary system for removing bile salts from the liver. In humans, deficiency of BSEP, which is encoded by the ABCB11 gene, causes severe progressive cholestatic liver disease from early infancy. In previous studies of Abcb11 deficiency in mice generated on a mixed genetic background, the animals did not recapitulate the human disease. We reasoned that ABCB11 deficiency may cause unique changes in hepatic metabolism that are predictive of liver injury. To test this possibility, we first determined that Abcb11 knock-out (KO) C57BL/6J mice recapitulate human deficiency. Before the onset of cholestasis, Abcb11 KO mice have altered hepatic lipid metabolism coupled with reduced expression of genes important in mitochondrial fatty acid oxidation. This was associated with increased serum free-fatty acids, reduced total white adipose, and marked impairment of long-chain fatty acid beta-oxidation. Importantly, metabolomic analysis confirmed that Abcb11 KO mice have impaired mitochondrial fatty acid beta-oxidation with the elevated fatty acid metabolites phenylpropionylglycine and phenylacetylglycine. These metabolic changes precede cholestasis but may be of relevance to cholestatic disease progression because altered fatty acid metabolism can enhance reactive oxygen species that might exacerbate cholestatic liver damage.

Here we show that the network is regulated by a ubiquitin signaling cascade initiated by RNF8 and its partner, UBC13, and mediated by FAAP20, a component of the FA core complex. FAAP20 preferentially binds the ubiquitin product of RNF8-UBC13, and this ubiquitin-binding activity and RNF8-UBC13 are both required for recruitment of FAAP20 to ICLs. Both RNF8 and FAAP20 are required for recruitment of FA core complex and FANCD2 to ICLs, whereas RNF168 can modulate efficiency of the recruitment. RNF8 and FAAP20 are needed for efficient FANCD2 monoubiquitination, a key step of the FA network; RNF8 and the FA core complex work in the same pathway to promote cellular resistance to ICLs. Thus, the RNF8-FAAP20 ubiquitin cascade is critical for recruiting FA core complex to ICLs and for normal function of the FA network.

TI Secondary Variants in Individuals Undergoing Exome Sequencing: Screening of 572 Individuals Identifies High-Penetrance Mutations in Cancer-Susceptibility Genes SO AMERICAN JOURNAL OF HUMAN GENETICS LA English DT Article ID MANAGING INCIDENTAL FINDINGS; DIFFUSE GASTRIC-CANCER; E-CADHERIN MUTATIONS; BREAST-CANCER; GERMLINE MUTATIONS; BRCA2; RECOMMENDATIONS; DATABASE; GENOME; CLASSIFICATION AB Genome- and exome-sequencing costs are continuing to fall, and many individuals are undergoing these assessments as research participants and patients. The issue of secondary (so-called incidental) findings in exome analysis is controversial, and data are needed on methods of detection and their frequency. We piloted secondary variant detection by analyzing exomes for mutations in cancer-susceptibility syndromes in subjects ascertained for atherosclerosis phenotypes. We performed exome sequencing on 572 ClinSeq participants, and in 37 genes, we interpreted variants that cause high-penetrance cancer syndromes by using an algorithm that filtered results on the basis of mutation type, quality, and frequency and that filtered mutation-database entries on the basis of defined categories of causation. We identified 454 sequence variants that differed from the human reference. Exclusions were made on the basis of sequence quality (26 variants) and high frequency in the cohort (77 variants) or dbSNP (17 variants), leaving 334 variants of potential clinical importance. These were further filtered on the basis of curation of literature reports. Seven participants, four of whom were of Ashkenazi Jewish descent and three of whom did not meet family-history-based referral criteria, had deleterious BRCA1 or BRCA2 mutations. One participant had a deleterious SDHC mutation, which causes paragangliomas. Exome sequencing, coupled with multidisciplinary interpretation, detected clinically important mutations in cancer-susceptibility genes; four of such mutations were in individuals without a significant family history of disease. We conclude that secondary variants of high clinical importance will be detected at an appreciable frequency in exomes, and we suggest that priority be given to the development of more efficient modes of interpretation with trials in larger patient groups.

TI Genetic Associations for Activated Partial Thromboplastin Time and Prothrombin Time, their Gene Expression Profiles, and Risk of Coronary Artery Disease SO AMERICAN JOURNAL OF HUMAN GENETICS LA English DT Article ID HISTIDINE-RICH GLYCOPROTEIN; GENOME-WIDE ASSOCIATION; VON-WILLEBRAND-FACTOR; DEEP-VEIN THROMBOSIS; ABO BLOOD-GROUP; PROTEIN-C; PLASMA-LEVELS; CELLULAR CHARACTERIZATION; VENOUS THROMBOEMBOLISM; HEMOSTASIS PHENOTYPES AB Activated partial thromboplastin time (aPTT) and prothrombin time (PT) are clinical tests commonly used to screen for coagulation-factor deficiencies. One genome-wide association study (GWAS) has been reported previously for aPTT, but no GWAS has been reported for PT. We conducted a GWAS and meta-analysis to identify genetic loci for aPTT and PT. The GWAS for aPTT was conducted in 9,240 individuals of European ancestry from the Atherosclerosis Risk in Communities (ARIC) study, and the GWAS for PT was conducted in 2,583 participants from the Genetic Study of Three Population Microisolates in South Tyrol (MICROS) and the Lothian Birth Cohorts (LBC) of 1921 and 1936. Replication was assessed in 1,041 to 3,467 individuals. For aPTT, previously reported associations with KNG1, HRG, F11, F12, and ABO were confirmed. A second independent association in ABO was identified and replicated (rs8176704, p = 4.26 x 10(-24)). Pooling the ARIC and replication data yielded two additional loci in F5 (rs6028, p = 3.22 x 10(-9)) and AGBL1 (rs2469184, p = 3.61 x 10(-8)). For PT, significant associations were identified and confirmed in F7 (rs561241, p = 3.71 x 10(-56)) and PROCR/EDEM2 (rs2295888, p = 5.25 x 10(-13)). Assessment of existing gene expression and coronary artery disease (CAD) databases identified associations of five of the GWAS loci with altered gene expression and two with CAD. In summary, eight genetic loci that account for similar to 29% of the variance in aPTT and two loci that account for similar to 14% of the variance in PT were detected and supported by functional data.

This study has served as a basis for a number of Genome-Wide Association Studies (GWAS) and other types of genetic analyses. Over a period of 5 years, 52,256 EPIC DNA samples have been extracted using an automated DNA extraction platform. Here we have evaluated the pre-analytical factors affecting DNA yield, including anthropometric, epidemiological and technical factors such as center of subject recruitment, age, gender, body-mass index, disease case or control status, tobacco consumption, number of aliquots of buffy coat used for DNA extraction, extraction machine or procedure, DNA quantification method, degree of haemolysis and variations in the timing of sample processing. We show that the largest significant variations in DNA yield were observed with degree of haemolysis and with center of subject recruitment. Age, gender, body-mass index, cancer case or control status and tobacco consumption also significantly impacted DNA yield. Feedback from laboratories which have analyzed DNA with different SNP genotyping technologies demonstrate that the vast majority of samples (approximately 88%) performed adequately in different types of assays. To our knowledge this study is the largest to date to evaluate the sources of pre-analytical variations in DNA extracted from peripheral leucocytes. The results provide a strong evidence-based rationale for standardized recommendations on blood collection and processing protocols for large-scale genetic studies.

TI An Overlapping Protein-Coding Region in Influenza A Virus Segment 3 Modulates the Host Response SO SCIENCE LA English DT Article ID PA SUBUNIT; CELL-DEATH; RNA; ENDONUCLEASE; DEGRADATION; SUPPRESSION; INFECTION; SIGNALS; BINDING; SYSTEM AB Influenza A virus (IAV) infection leads to variable and imperfectly understood pathogenicity. We report that segment 3 of the virus contains a second open reading frame ("X-ORF"), accessed via ribosomal frameshifting. The frameshift product, termed PA-X, comprises the endonuclease domain of the viral PA protein with a C-terminal domain encoded by the X-ORF and functions to repress cellular gene expression. PA-X also modulates IAV virulence in a mouse infection model, acting to decrease pathogenicity. Loss of PA-X expression leads to changes in the kinetics of the global host response, which notably includes increases in inflammatory, apoptotic, and T lymphocyte-signaling pathways. Thus, we have identified a previously unknown IAV protein that modulates the host response to infection, a finding with important implications for understanding IAV pathogenesis. C1 [Jagger, B.

TI Sustained Exendin-4 Secretion through Gene Therapy Targeting Salivary Glands in Two Different Rodent Models of Obesity/Type 2 Diabetes SO PLOS ONE LA English DT Article ID GLUCAGON-LIKE PEPTIDE-1; LEBERS CONGENITAL AMAUROSIS; GLP-1 RECEPTOR AGONISTS; INSULIN SENSITIVITY; EXPRESSION; DELIVERY; VECTORS; RELEASE; MICE; HOMEOSTASIS AB Exendin-4 (Ex-4) is a Glucagon-like peptide 1 (GLP-1) receptor agonist approved for the treatment of Type 2 Diabetes (T2DM), which requires daily subcutaneous administration. In T2DM patients, GLP-1 administration is reported to reduce glycaemia and HbA1c in association with a modest, but significant weight loss. The aim of present study was to characterize the site-specific profile and metabolic effects of Ex-4 levels expressed from salivary glands (SG) in vivo, following adenoassociated virus-mediated (AAV) gene therapy in two different animal models of obesity prone to impaired glucose tolerance and T2DM, specifically, Zucker fa/fa rats and high fed diet (HFD) mice. Following percutaneous injection of AAV5 into the salivary glands, biologically active Ex-4 was detected in the blood of both animal models and expression persisted in salivary gland ductal cell until the end of the study. In treated mice, Ex-4 levels averaged 138.9 +/- 42.3 pmol/L on week 6 and in treated rats, mean circulating Ex-4 levels were 238.2 +/- 72 pmol/L on week 4 and continued to increase through week 8. Expression of Ex-4 resulted in a significant decreased weight gain in both mice and rats, significant improvement in glycemic control and/or insulin sensitivity as well as visceral adipose tissue adipokine profile. In conclusion, these results suggest that sustained site-specific expression of Ex-4 following AAV5-mediated gene therapy is feasible and may be useful in the treatment of obesity as well as trigger improved metabolic profile.

Here we follow the course of phosphodiester bond formation using time-resolved X-ray crystallography. Native human DNA polymerase eta, DNA and dATP were co-crystallized at pH 6.0 without Mg2+. The polymerization reaction was initiated by exposing crystals to 1 mM Mg2+ at pH 7.0, and stopped by freezing at desired time points for structural analysis. The substrates and two Mg2+ ions are aligned within 40 s, but the bond formation is not evident until 80 s. From 80 to 300 s structures show a mixture of decreasing substrate and increasing product of the nucleotidyl-transfer reaction. Transient electron densities indicate that deprotonation and an accompanying C2'-endo to C3'-endo conversion of the nucleophile 3'-OH are rate limiting. A third Mg2+ ion, which arrives with the new bond and stabilizes the intermediate state, may be an unappreciated feature of the two-metal-ion mechanism.

TI Rsx is a metatherian RNA with Xist-like properties in X-chromosome inactivation SO NATURE LA English DT Article ID PRIMORDIAL GERM-CELLS; DOSAGE COMPENSATION; MOUSE; GENE; METHYLATION; EXPRESSION; MAMMALS AB In female (XX) mammals, one of the two X chromosomes is inactivated to ensure an equal dose of X-linked genes with males (XY)(1). X-chromosome inactivation in eutherian mammals is mediated by the non-coding RNA Xist(2). Xist is not found in metatherians(3) (marsupials), and how X-chromosome inactivation is initiated in these mammals has been the subject of speculation for decades(4). Using the marsupial Monodelphis domestica, here we identify Rsx (RNA-on-the-silent X), an RNA that has properties consistent with a role in X-chromosome inactivation. Rsx is a large, repeat-rich RNA that is expressed only in females and is transcribed from, and coats, the inactive X chromosome. In female germ cells, in which both X chromosomes are active, Rsx is silenced, linking Rsx expression to X-chromosome inactivation and reactivation. Integration of an Rsx transgene on an autosome in mouse embryonic stem cells leads to gene silencing in cis. Our findings permit comparative studies of X-chromosome inactivation in mammals and pose questions about the mechanisms by which X-chromosome inactivation is achieved in eutherians.

In this report, we demonstrate the central role of CDP-diacylglycerol synthetase (CDS) in the regulation of VEGFA signaling and angiogenesis. CDS activity maintains phosphoinositide 4,5 bisphosphate (PIP2) availability through resynthesis of phosphoinositides, whereas VEGFA, mainly through phospholipase C gamma 1, consumes PIP2 for signal transduction. Loss of CDS2, 1 of 2 vertebrate CDS enzymes, results in vascular-specific defects in zebrafish in vivo and failure of VEGFA-induced angiogenesis in endothelial cells in vitro. Absence of CDS2 also results in reduced arterial differentiation and reduced angiogenic signaling. CDS2 arterial differentiation and reduced angiogenic signaling. CDS2 deficit-caused phenotypes can be successfully rescued by artificial elevation of PIP2 levels, and excess PIP2 or increased CDS2 activity can promote excess angiogenesis. These results suggest that availability of CDS-controlled resynthesis of phosphoinositides is essential for angiogenesis.

Msg diversity may represent a mechanism for immune escape from host T cell responses. We examined splenic T cell proliferative and cytokine as well as serum antibody responses to recombinant and native Pneumocystis antigens in immunized or Pneumocystis-infected mice. In addition, immune responses were examined in 5 healthy humans. Results: Proliferative responses to each of two recombinant Msg variant proteins were seen in mice immunized with either recombinant protein, but no proliferation to these antigens was seen in mice immunized with crude Pneumocystis antigens or in mice that had cleared infection, although the latter animals demonstrated proliferative responses to crude Pneumocystis antigens and native Msg. IL-17 and MCP-3 were produced in previously infected animals in response to the same antigens, but not to recombinant antigens. Antibody responses to the recombinant P. murina Msg variant proteins were seen in all groups of animals, demonstrating that all groups were exposed to and mounted immune responses to Msg. No human PBMC samples proliferated following stimulation with P. jirovecii Msg, while antibody responses were detected in sera from 4 of 5 samples. Conclusions: Cross-reactive antibody responses to Msg variants are common, while cross-reactive T cell responses are uncommon; these results support the hypothesis that Pneumocystis utilizes switching of Msg variant expression to avoid host T cell responses.

TI Association between Genetic Variants in DNA and Histone Methylation and Telomere Length SO PLOS ONE LA English DT Article ID GENOME-WIDE ASSOCIATION; EPIGENETIC REGULATION; METHYLTRANSFERASE BHMT; BETAINE-HOMOCYSTEINE; OXIDATIVE STRESS; MAMMALIAN-CELLS; ARGININE; DISEASE; HUMANS; FAMILY AB Telomere length, a biomarker of aging and age-related diseases, exhibits wide variation between individuals. Common genetic variation may explain some of the individual differences in telomere length. To date, however, only a few genetic variants have been identified in the previous genome-wide association studies. As emerging data suggest epigenetic regulation of telomere length, we investigated 72 single nucleotide polymorphisms (SNPs) in 46 genes that involve DNA and histone methylation as well as telomerase and telomere-binding proteins and DNA damage response. Genotyping and quantification of telomere length were performed in blood samples from 989 non-Hispanic white participants of the Sister Study, a prospective cohort of women aged 35-74 years. The association of each SNP with logarithmically-transformed relative telomere length was estimated using multivariate linear regression. Six SNPs were associated with relative telomere length in blood cells with p-values<0.05 (uncorrected for multiple comparisons). The minor alleles of BHMT rs3733890 G>A (p = 0.041), MTRR rs2966952 C>T (p = 0.002) and EHMT2 rs558702 G>A (p = 0.008) were associated with shorter telomeres, while minor alleles of ATM rs1801516 G>A (p = 0.031), MTR rs1805087 A>G (p = 0.038) and PRMT8 rs12299470 G>A (p = 0.019) were associated with longer telomeres. Five of these SNPs are located in genes coding for proteins involved in DNA and histone methylation. Our results are consistent with recent findings that chromatin structure is epigenetically regulated and may influence the genomic integrity of telomeric region and telomere length maintenance. Larger studies with greater coverage of the genes implicated in DNA methylation and histone modifications are warranted to replicate these findings.

Adaptation, in the H2 hemagglutinin derived from an avian virus, includes the ability to bind to the mammalian receptor, a significant prerequisite for infection of mammals, in particular humans, which poses a big concern for public health. Here we investigated the pathogenic potential of swine H2N3 in Cynomolgus macaques, a surrogate model for human influenza infection. In contrast to human H2N2 virus, which served as a control and largely caused mild pneumonia similar to seasonal influenza A viruses, the swine H2N3 virus was more pathogenic causing severe pneumonia in nonhuman primates. Both viruses replicated in the entire respiratory tract, but only swine H2N3 could be isolated from lung tissue on day 6 post infection. All animals cleared the infection whereas swine H2N3 infected macaques still presented with pathologic changes indicative of chronic pneumonia at day 14 post infection. Swine H2N3 virus was also detected to significantly higher titers in nasal and oral swabs indicating the potential for animal-to-animal transmission. Plasma levels of IL-6, IL-8, MCP-1 and IFN gamma were significantly increased in swine H2N3 compared to human H2N2 infected animals supporting the previously published notion of increased IL-6 levels being a potential marker for severe influenza infections. In conclusion, the swine H2N3 virus represents a threat to humans with the potential for causing a larger outbreak in a non-immune or partially immune population. Furthermore, surveillance efforts in farmed pig populations need to become an integral part of any epidemic and pandemic influenza preparedness.

A TaqMan low-density array (TLDA) was used to characterise the expression of 380 genes associated with chemotherapy resistance in IGROVCDDP cells. Paclitaxel resistance in IGROVCDDP is mediated by gene and protein overexpression of P-glycoprotein and the protein is functionally active. Cisplatin resistance was not reversed by elacridar, confirming that cisplatin is not a P-glycoprotein substrate. Cisplatin resistance in IGROVCDDP is multifactorial and is mediated in part by the glutathione pathway and decreased accumulation of drug. Total cellular glutathione was not increased. However, the enzyme activity of GSR and GGT1 were up-regulated. The cellular localisation of copper transporter CTR1 changed from membrane associated in IGROV-1 to cytoplasmic in IGROVCDDP. This may mediate the previously reported accumulation defect. There was decreased expression of the sodium potassium pump (ATP1A), MRP1 and FBP which all have been previously associated with platinum accumulation defects in platinum-resistant cell lines. Cellular localisation of MRP1 was also altered in IGROVCDDP shifting basolaterally, compared to IGROV-1. BRCA1 was also up-regulated at the gene and protein level. The overexpression of P-glycoprotein in a resistant model developed with cisplatin is unusual. This demonstrates that P-glycoprotein can be upregulated as a generalised stress response rather than as a specific response to a substrate. Mechanisms characterised in IGROVCDDP cells may be applicable to relapsed ovarian cancer patients treated with frontline platinum/taxane chemotherapy.

For HIV-1, experimental models are needed to identify vaccine regimens capable of eliciting desired immune responses, such as broadly neutralizing antibodies (bNAbs). One important neutralization target on the HIV-1 envelope glycoproteins (Envs) is the conserved primary CD4 receptor binding site (CD4bs). The isolation and characterization of CD4bs-specific neutralizing monoclonal Abs (mAbs) from HIV-1-infected individuals have provided insights into how broadly reactive Abs target this conserved epitope. In contrast, and for reasons that are not understood, current Env immunogens elicit CD4bs-directed Abs with limited neutralization breadth. To facilitate the use of the NHP model to address this and other questions relevant to human humoral immunity, we defined features of the rhesus macaque immunoglobulin (Ig) loci and compared these to the human Ig loci. We then studied Env-immunized rhesus macaques, identified single B cells expressing CD4bs-specific Abs, and sequenced and expressed a panel of functional mAbs. Comparison of vaccine-elicited mAbs with HIV-1 infection-induced mAbs revealed differences in the degree of somatic hypermutation of the Abs as well as in the fine specificities targeted within the CD4bs. These data support the use of the preclinical NHP model to characterize vaccine-induced B cell responses at high resolution. C1 [Sundling, Christopher; Huynh, Nick; Hedestam, Gunilla B.

TI Leading the way: finding genes for neurologic disease in dogs using genome-wide mRNA sequencing SO BMC GENETICS LA English DT Article DE Dogs; RNAseq; Cortical degeneration; Canines; Neurodegenerative diseases; SPTBN2 gene ID DOMESTIC DOG; LINKAGE DISEQUILIBRIUM; BREEDS; DEGENERATION AB Because of dogs' unique population structure, human-like disease biology, and advantageous genomic features, the canine system has risen dramatically in popularity as a tool for discovering disease alleles that have been difficult to find by studying human families or populations. To date, disease studies in dogs have primarily employed either linkage analysis, leveraging the typically large family size, or genome-wide association, which requires only modest-sized case and control groups in dogs. Both have been successful but, like most techniques, each requires a specific combination of time and money, and there are inherent problems associated with each. Here we review the first report of mRNA-Seq in the dog, a study that provides insights into the potential value of applying high-throughput sequencing to the study of genetic diseases in dogs. Forman and colleagues apply high-throughput sequencing to a single case of canine neonatal cerebellar cortical degeneration. This implementation of whole genome mRNA sequencing, the first reported in dog, is additionally unusual due to the analysis: the data was used not to examine transcript levels or annotate genes, but as a form of target capture that revealed the sequence of transcripts of genes associated with ataxia in humans. This approach entails risks. It would fail if, for example, the relevant transcripts were not sufficiently expressed for genotyping or were not associated with ataxia in humans. But here it pays off handsomely, identifying a single frameshift mutation that segregates with the disease. This work sets the stage for similar studies that take advantage of recent advances in genomics while exploiting the historical background of dog breeds to identify disease-causing mutations.

Using a chemoinformatics approach, we sought to "de-orphanize" drugs that lack primary targets. Surprisingly, targets could be easily predicted for many: Whereas these targets were not known to us nor to the common databases, most could be confirmed by literature search, leaving only 13 Food and Drug Administration-approved drugs with unknown targets; the number of drugs without molecular targets likely is far fewer than reported. The number of worldwide drugs without reasonable molecular targets similarly dropped, from 352 (25%) to 44 (4%). Nevertheless, there remained at least seven drugs for which reasonable mechanism-of-action targets were unknown but could be predicted, including the antitussives clemastine, cloperastine, and nepinalone; the antiemetic benzquinamide; the muscle relaxant cyclobenzaprine; the analgesic nefopam; and the immunomodulator lobenzarit. For each, predicted targets were confirmed experimentally, with affinities within their physiological concentration ranges. Turning this question on its head, we next asked which drugs were specific enough to act as chemical probes. Over 100 drugs met the standard criteria for probes, and 40 did so by more stringent criteria. A chemical information approach to drug-target association can guide therapeutic development and reveal applications to probe biology, a focus of much current interest.

To investigate whether these foci represent GalR-mediated association of some of the GalR specific DNA binding sites (gal operators), we used the chromosome conformation capture (3C) method in vivo. Our 3C data demonstrate that, in stationary phase cells, many of the operators distributed around the chromosome are interacted. By the use of atomic force microscopy, we showed that the observed remote chromosomal interconnections occur by direct interactions between DNA-bound GalR not involving any other factors. Mini plasmid DNA circles with three or five operators positioned at defined loci showed GalR-dependent loops of expected sizes of the intervening DNA segments. Our findings provide unique evidence that a transcription factor participates in organizing the chromosome in a three-dimensional structure. We believe that these chromosomal connections increase local concentration of GalR for coordinating the regulation of widely separated target genes, and organize the chromosome structure in space, thereby likely contributing to chromosome compaction.

TI Prenatal growth in humans and postnatal brain maturation into late adolescence SO PROCEEDINGS OF THE NATIONAL ACADEMY OF SCIENCES OF THE UNITED STATES OF AMERICA LA English DT Article ID BIRTH-WEIGHT DISCORDANCE; HUMAN CEREBRAL-CORTEX; DEVELOPMENTAL HISTORY; CORTICAL THICKNESS; SUBPLATE ZONE; IN-UTERO; FETAL; CHILDHOOD; RESTRICTION; SCHIZOPHRENIA AB Prenatal life encompasses a critical phase of human brain development, but neurodevelopmental consequences of normative differences in prenatal growth among full-term pregnancies remain largely uncharted. Here, we combine the power of a within-monozygotic twin study design with longitudinal neuroimaging methods that parse dissociable components of structural brain development between ages 3 and 30 y, to show that subtle variations of the in utero environment, as indexed by mild birth weight (BW) variation within monozygotic pairs, are accompanied by statistically significant (i) differences in postnatal intelligence quotient (IQ) and (ii) alterations of brain anatomy that persist at least into late adolescence. Greater BW within the normal range confers a sustained and generalized increase in brain volume, which in the cortical sheet, is specifically driven by altered surface area rather than cortical thickness. Surface area is maximally sensitive to BW variation within cortical regions implicated in the biology of several mental disorders, the risk for which is modified by normative BW variation. We complement this near-experimental test of prenatal environmental influences on human brain development by replicating anatomical findings in dizygotic twins and unrelated singletons. Thus, using over 1,000 brain scans, across three independent samples, we link subtle differences in prenatal growth, within ranges seen among the majority of human pregnancies, to protracted surface area alterations, that preferentially impact later-maturing associative cortices important for higher cognition. By mapping the sensitivity of postnatal human brain development to prenatal influences, our findings underline the potency of in utero life in shaping postnatal outcomes of neuroscientific and public health importance.

The Anopheles gambiae L3-5 refractory (R) line melanizes most Plasmodium species, including the Brazilian P. falciparum 7G8 line, but it is highly susceptible to some African P. falciparum strains such as 3D7, NF54, and GB4. We investigated whether these lines differ in their ability to evade the mosquito immune system. Silencing key components of the mosquito complement-like system[ thioester-containing protein 1 (TEP1), leucine-rich repeat protein 1, and Anopheles Plasmodium-responsive leucine-rich repeat protein 1] prevented melanization of 7G8 parasites, reverting the refractory phenotype. In contrast, it had no effect on the intensity of infection with NF54, suggesting that this line is able to evade TEP1-mediated lysis. When R females were coinfected with a line that is melanized (7G8) and a line that survives (3D7), the coinfection resulted in mixed infections with both live and encapsulated parasites on individual midguts. This finding shows that survival of individual parasites is parasite-specific and not systemic in nature, because parasites can evade TEP1-mediated lysis even when other parasites are melanized in the same midgut. When females from an extensive genetic cross between R and susceptible A. gambiae (G3) mosquitoes were infected with P. berghei, encapsulation was strongly correlated with the TEP1-R1 allele. However, P. falciparum 7G8 parasites were no longer encapsulated by females from this cross, indicating that the TEP1-R1 allele is not sufficient to melanize this line. Evasion of the A. gambiae immune system by P. falciparum may be the result of parasite adaptation to sympatric mosquito vectors and may be an important factor driving malaria transmission.

We show that such a membrane is equivalent to a system of effective charges located at opposite sides of the membrane offering a computationally efficient way to model correlation effects in water-filled nanopore membranes. Based on our simulations we predict that membranes with square pore lattices undergo a continuous order-disorder transition to an antiferroelectric low-temperature phase in which water wires in adjacent pores are oriented in opposite directions. Strong antiferroelectric correlations exist also in the disordered phase far above the critical temperature or in membranes with geometric frustration, leading to a dielectric constant that is reduced considerably with respect to the case of uncoupled water wires. These correlations are also expected to hinder proton translocation through the membrane. C1 [Menzl, Georg; Dellago, Christoph] Univ Vienna, Fac Phys, A-1090 Vienna, Austria.

Indeed, cellular miRNAs target and hybridize to specific sequences of both HTLV-1 and HIV-1 viral transcripts. However, much like the variety of host immune responses to retroviral infection, the virus itself contains mechanisms that assist in the evasion of viral inhibition through control of the cellular RNAi pathway. Retroviruses can hijack both the enzymatic and catalytic components of the RNAi pathway, in some cases to produce novel viral miRNAs that can either assist in active viral infection or promote a latent state. Here, we show that HTLV-1 Tax contributes to the dysregulation of the RNAi pathway by altering the expression of key components of this pathway. A survey of uninfected and HTLV-1 infected cells revealed that Drosha protein is present at lower levels in all HTLV-1 infected cell lines and in infected primary cells, while other components such as DGCR8 were not dramatically altered. We show colocalization of Tax and Drosha in the nucleus in vitro as well as coimmunoprecipitation in the presence of proteasome inhibitors, indicating that Tax interacts with Drosha and may target it to specific areas of the cell, namely, the proteasome. In the presence of Tax we observed a prevention of primary miRNA cleavage by Drosha. Finally, the changes in cellular miRNA expression in HTLV-1 infected cells can be mimicked by the add back of Drosha or the addition of antagomiRs against the cellular miRNAs which are downregulated by the virus.

TI Multicenter, Double-Blind, Placebo-Controlled, Randomized Phase II Trial of Gemcitabine/Cisplatin Plus Bevacizumab or Placebo in Patients With Malignant Mesothelioma SO JOURNAL OF CLINICAL ONCOLOGY LA English DT Article ID LEUKEMIA GROUP-B; ENDOTHELIAL GROWTH-FACTOR; CELL LUNG-CANCER; PLEURAL MESOTHELIOMA; CISPLATIN; SURVIVAL; VEGF; CHEMOTHERAPY; COMBINATION; PACLITAXEL AB Purpose Gemcitabine plus cisplatin is active in malignant mesothelioma (MM), although single-arm phase II trials have reported variable outcomes. Vascular endothelial growth factor (VEGF) inhibitors have activity against MM in preclinical models. We added the anti-VEGF antibody bevacizumab to gemcitabine/cisplatin in a multicenter, double-blind, placebo-controlled randomized phase II trial in patients with previously untreated, unresectable MM. Patients and Methods Eligible patients had an Eastern Cooperative Oncology Group (ECOG) performance status of 0 to 1 and no thrombosis, bleeding, or major blood vessel invasion. The primary end point was progression-free survival (PFS). Patients were stratified by ECOG performance status (0 v 1) and histologic subtype (epithelial v other). Patients received gemcitabine 1,250 mg/m(2) on days 1 and 8 every 21 days, cisplatin 75 mg/m(2) every 21 days, and bevacizumab 15 mg/kg or placebo every 21 days for six cycles, and then bevacizumab or placebo every 21 days until progression. Results One hundred fifteen patients were enrolled at 11 sites; 108 patients were evaluable. Median PFS time was 6.9 months for the bevacizumab arm and 6.0 months for the placebo arm (P = .88). Median overall survival (OS) times were 15.6 and 14.7 months in the bevacizumab and placebo arms, respectively (P = .91). Partial response rates were similar (24.5% for bevacizumab v 21.8% for placebo; P = .74). A higher pretreatment plasma VEGF concentration (n = 56) was associated with shorter PFS (P = .02) and OS (P = .0066), independent of treatment arm. There were no statistically significant differences in toxicity of grade 3 or greater. Conclusion The addition of bevacizumab to gemcitabine/cisplatin in this trial did not significantly improve PFS or OS in patients with advanced MM.

These signals are required to overcome inhibition mediated by the E3 ubiquitin ligase c-Cbl of the guanine nucleotide exchange factor Vav1, which promotes activation of NK cells. Here, we showed that the adaptor protein SLP-76 (Src homology 2 domain-containing leukocyte phosphoprotein of 76 kD) was required for this synergy and that distinct tyrosine residues in SLP-76 were phosphorylated by each member of a pair of synergistic receptors. Selective phosphorylation of tyrosine 113 or tyrosine 128 in SLP-76 enabled binding of SLP-76 to Vav1. Selective phosphorylation of SLP-76 at these residues was restricted to receptors that stimulated ligand-dependent target cell killing; antibody-dependent stimulation of the Fc receptor CD16 promoted phosphorylation at both sites. Knockdown and reconstitution experiments with SLP-76 mutant proteins showed the distinct role of each tyrosine in the synergistic mobilization of Ca2+, revealing an unexpected degree of selectivity in the phosphorylation of SLP-76 by NK cell co-activation receptors. Together, these data suggest that combined phosphorylation of separate tyrosine residues in SLP-76 forms the basis of synergistic NK cell activation.

It has been demonstrated that CEACAM6 is a potential target for monoclonal antibody (mAb) therapy with a safe therapeutic index. Here, we labeled three anti-CEACAM6 antibodies of different sizes, including a single-domain antibody 2A3 (16 kDa), a heavy chain antibody 2A3-mFc (80 kDa) and a full length antibody 9A6 (150 kDa), with Cu-64 to image CEACAM6 expression in a xenografted pancreatic tumor model. For positron emission tomography (PET) imaging, the tumor mice were intravenously injected with Cu-64-DOTA-antibodies and static scans were obtained at 5 min, 0.5, 1, 2, 4, 8 and 24 h post-injection (p.i.). All three antibodies showed strong CEACAM6 binding. Ex vivo immunostaining on tumor sections at 24 h after Ab injection demonstrated specific tumor targeting of both 2A3-mFc and 9A6. Cu-64-DOTA-2A3 showed fast BxPC3 tumor uptake and rapid whole-body clearance. At 24 h p.i., the tumor uptakes were 98.2 +/- 6.12% ID/g for Cu-64-DOTA-2A3-mFc and 57.8 +/- 3.73% ID/g for Cu-64-DOTA-9A6, respectively. Compared with the full length antibody 9A6, the heavy chain antibody 2A3-mFc showed higher tumor uptake, lower liver uptake and shorter circulation half-life. All the data supported that the heavy chain antibody 2A3-mFc is superior to the single domain antibody and the full-length antibody with regard to tumor detection and pharmacokinetics, which has great potential to be developed for CEACAM6-targeted pancreatic cancer imaging and therapy.

The human cervicovaginal microbiome affects female reproductive health, susceptibility to and natural history of many sexually transmitted infections, including human papillomavirus (HPV). At present, long-term behavior of the cervical microbiome in early sexual life is poorly understood. Methods: The V6 and V6-V9 regions of the 16S ribosomal RNA gene were amplified from DNA isolated from exfoliated cervical cells. Specimens from 10 women participating in the Natural History Study of HPV in Guanacaste, Costa Rica were sampled successively over a period of 5-7 years. We sequenced amplicons using 3 different platforms (Sanger, Roche 454, and Illumina HiSeq 2000) and analyzed sequences using pipelines based on 3 different classification algorithms (usearch, RDP Classifier, and pplacer). Results: Usearch and pplacer provided consistent microbiome classifications for all sequencing methods, whereas RDP Classifier deviated significantly when characterizing Illumina reads. Comparing across sequencing platforms indicated 7%-41% of the reads were reclassified, while comparing across software pipelines reclassified up to 32% of the reads. Variability in classification was shown not to be due to a difference in read lengths. Six cervical microbiome community types were observed and are characterized by a predominance of either G. vaginalis or Lactobacillus spp. Over the 5-7 year period, subjects displayed fluctuation between community types. A PERMANOVA analysis on pairwise Kantorovich-Rubinstein distances between the microbiota of all samples yielded an F-test ratio of 2.86 (p<0.01), indicating a significant difference comparing within and between subjects' microbiota. Conclusions: Amplification and sequencing methods affected the characterization of the microbiome more than classification algorithms. Pplacer and usearch performed consistently with all sequencing methods. The analyses identified 6 community types consistent with those previously reported. The long-term behavior of the cervical microbiome indicated that fluctuations were subject dependent.

The measured pulse-echo waveform showed the transducer had center frequency of 57.5 MHz with 54% bandwidth and 14 dB insertion loss. To evaluate the performance of this type of transducer, in vitro ultrasonic biomicroscopy imaging on the rabbit eye was obtained. Moreover, a single beam acoustic trapping experiment was performed using this transducer. Trapping of targeted particle size smaller than the ultrasonic wavelength was observed. Potential applications of these devices include minimally invasive measurements of retinal blood flow and single beam acoustic trapping of microparticles. (C) 2012 American Institute of Physics.

Here, we investigated the role of SLAT/Def6 in the development of experimental autoimmune uveitis (EAU), an animal model for several uveitic conditions in humans. Methods: SLAT/Def6 deficient ("KO") mice and C57BL/6 controls were immunized with interphotoreceptor retinoid-binding protein (IRBP), along with pertussis toxin. The development of ocular inflammation was determined by both fundoscopy and histological examination. Lymphoid cells from draining lymph nodes were cultured with IRBP to measure lymphocyte proliferation and release of cytokines. Purified dendritic cells were tested for their capacity to present antigen to responding lymphocytes. In addition, the lymphoid cells were tested for the expression of forkhead box P3 (FoxP3), using conventional methods, and the activity of T-regulatory cells was determined by their capacity to inhibit in vitro proliferative responses. Serum anti -IRBP antibody levels were measured by enzyme-linked immonosorbant assay (ELISA). quantitative polymerase chain reaction (qPCR) was used to determine the transcript levels of cytokines in inflamed eyes. Results: SLAT/Def6 KO mice had significantly reduced EAU compared to controls. Cells isolated from draining lymph nodes of SLAT/Def6 KO mice exhibited impaired proliferation and production of Th1 and Th17 signature cytokines (interferon [IFN]-gamma and interleukin [IL]-17, respectively) when compared with cells isolated from control mice. qPCR of inflamed eyes detected similar levels of IFN-gamma transcript in control and SLAT/Def6 KO mice, whereas the IL-17 transcript levels in eyes of the SLAT/Def6 KO mice were lower than in eyes of the controls. The SLAT/Def6 KO mice resembled their wild type (WT) controls, however, in the levels of their serum antibody against IRBP, the antigen presenting capacity of their dendritic cells, the proportion of cells expressing Foxp3 and the immunosuppressive activity of their T-regulatory cells. Conclusions: SLAT/Def6 KO mice exhibit reduced capacity to develop ocular inflammation and cellular activity when immunized with IRBP. Our study provides new data showing that SLAT/Def6 plays a major role in the T cell-mediated autoimmune processes that bring about the inflammatory eye disease, EAU.

TI Early-life and contemporaneous nutritional and environmental predictors of antibody response to vaccination in young Gambian adults SO VACCINE LA English DT Article DE Vaccine responses; Immune programming; Birth weight; Infant growth; Gambia ID STREPTOCOCCUS-PNEUMONIAE; NASOPHARYNGEAL CARRIAGE; IMMUNE-RESPONSE; BIRTH SEASON; BREAST-MILK; VITAMIN-A; CHILDREN; INFANTS; MORTALITY; SUPPLEMENTATION AB Recent research links nutritional exposures early in life with alterations in functional immunity that persist beyond childhood. Here we investigate predictors of antibody response to polysaccharide vaccines in a cohort of Gambian adults with detailed records from birth and early infancy available. 320 adults were given a single dose of a Vi polysaccharide vaccine for Salmonella typhi and a 23-valent capsular polysaccharide pneumococcal vaccine. Anti-Vi antibody levels and antibodies against 4 pneumococcal serotypes (1.5. 14 and 23F) were measured in serum samples collected at baseline and then 14 days following vaccination and compared to data available from birth and early infancy. Post-vaccination antibody titres to serotype 14 of the pneumococcal vaccine were negatively associated with rate of growth from birth to three months of age, infant weight at 12 months of age and season of birth, but no other associations were observed with early-life exposures. The strongest predictor of antibody levels was pre-vaccination antibody titres, with adult height and serum neopterin levels at time of vaccination also implicated. The current study does not support the hypothesis that nutritional exposures early in life consistently compromise antibody response to polysaccharide vaccines administered in young adulthood.

TI Cost of production of live attenuated dengue vaccines: A case study of the Institut Butantan, Sao Paulo, Brazil SO VACCINE LA English DT Article DE Cost of production; Dengue; Vaccine ID INFECTIONS; DEMAND; VIRUS AB Background: A vaccine to prevent dengue disease is urgently needed. Fortunately, a few tetravalent candidate vaccines are in the later stages of development and show promise. But, if the cost of these candidates is too high, their beneficial potential will not be realized. The price of a vaccine is one of the most important factors affecting its ultimate application in developing countries. In recent years, new vaccines such as those for human papilloma virus and pneumococcal disease (conjugate vaccine) have been introduced with prices in developed countries exceeding $50 per dose. These prices are above the level affordable by developing countries. In contrast, other vaccines such as those against Japanese encephalitis (SA14-14-2 strain vaccine) and meningitis type A have prices in developing countries below one dollar per dose, and it is expected that their introduction and use will proceed more rapidly. Because dengue disease is caused by four related viruses, vaccines must be able to protect against all four. Although there are several live attenuated dengue vaccine candidates under clinical evaluation, there remains uncertainty about the cost of production of these tetravalent vaccines, and this uncertainty is an impediment to rapid progress in planning for the introduction and distribution of dengue vaccines once they are licensed. Method: We have undertaken a detailed economic analysis, using standard industrial methodologies and applying generally accepted accounting practices, of the cost of production of a live attenuated vaccine, originally developed at the US National Institutes of Health (National Institute of Allergy and Infectious Diseases), to be produced at the Institut Butantan in Sao Paulo, Brazil. We determined direct costs of materials, direct costs of personnel and labor, indirect costs, and depreciation. These were analyzed assuming a steady-state production of 60 million doses per year. Results: Although this study does not seek to compute the price of the final licensed vaccine, the cost of production estimate produced here leads to the conclusion that the vaccine can be made available at a price that most ministries of health in developing countries could afford. This conclusion provides strong encouragement for supporting the development of the vaccine so that, if it proves to be safe and effective, licensure can be achieved soon and the burden of dengue disease can be reduced.

We find that HttQP103, which has a polyproline region at the C-terminal end of the polyQ repeat region, is significantly more toxic in [PSI+] yeast than in [PIN+], even though HttQP103 formed multiple aggregates in both [PSI+] and [PIN+] yeast. This toxicity was only observed in the strong [PSI+] variant, not the weak [PSI+] variant, which has more soluble Sup35 present than the strong variant. Furthermore, expression of the MC domains of Sup35, which retains the C-terminal domain of Sup35, but lacks the N-terminal prion domain, almost completely rescued HttQP103 toxicity, but was less effective in rescuing HttQ103 toxicity. Therefore, the toxicity of HttQP103 in yeast containing the [PSI+] prion is primarily due to sequestration of the essential protein, Sup35.

Although the O-GlcNAc modification of RNA polymerase II CTD was documented in 1993, its functional significance remained obscure. We show that O-GlcNAc transferase (OGT) modified CTD serine residues 5 and 7. Drug inhibition of OGT and OGA (N-acetylglucosaminidase) blocked transcription during preinitiation complex assembly. Polymerase II and OGT co-immunoprecipitated, and OGT is a component of the preinitiation complex. OGT shRNA experiments showed that reduction of OGT causes a reduction in transcription and RNA polymerase II occupancy at several B-cell promoters. These data suggest that the cycling of O-GlcNAc on and off of polymerase II occurs during assembly of the preinitiation complex. Our results define unexpected roles for both the CTD and O-GlcNAc in the regulation of transcription initiation in higher eukaryotes.

To date, the BRC repeat has not been observed in other proteins, so that its role in HR is inferred only in the context of BRCA2. Here, we identified a BRC repeat variant, named BRCv, in the RECQL5 helicase, which possesses anti-recombinase activity in vitro and suppresses HR and promotes cellular resistance to camptothecin-induced replication stress in vivo. RECQL5-BRCv interacted with RAD51 through two conserved motifs similar to those in the BRCA2-BRC repeat. Mutations of either motif compromised functions of RECQL5, including association with RAD51, inhibition of RAD51-mediated D-loop formation, suppression of sister chromatid exchange, and resistance to camptothecin-induced replication stress. Potential BRCvs were also found in other HR regulatory proteins, including Srs2 and Sgs1, which possess anti-recombinase activities similar to that of RECQL5. A point mutation in the predicted Srs2-BRCv disrupted the ability of the protein to bind RAD51 and to inhibit D-loop formation. Thus, BRC is a common RAD51 interaction module that can be utilized by different proteins to either promote HR, as in the case of BRCA2, or to suppress HR, as in RECQL5. C1 [Islam, M.

The IIA(Chb)-HPr complex completes the structure elucidation of representative cytoplasmic complexes for all four sugar branches of the bacterial phosphoryl transfer system (PTS). The active site His-89 of IIA(Chb) was mutated to Glu to mimic the phosphorylated state. IIA(Chb)(H89E) and HPr form a weak complex with a K-D of similar to 0.7 mM. The interacting binding surfaces, concave for IIA(Chb) and convex for HPr, complement each other in terms of shape, residue type, and charge distribution, with predominantly hydrophobic residues, interspersed by some uncharged polar residues, located centrally, and polar and charged residues at the periphery. The active site histidine of HPr, His-15, is buried within the active site cleft of IIA(Chb) formed at the interface of two adjacent subunits of the IIA(Chb) trimer, thereby coming into close proximity with the active site residue, H89E, of IIA(Chb). A His89-P-His-15 pentacoordinate phosphoryl transition state can readily be modeled without necessitating any significant conformational changes, thereby facilitating rapid phosphoryl transfer. Comparison of the IIA(Chb)-HPr complex with the IIA(Chb)-IIBChb complex, as well as with other cytoplasmic complexes of the PTS, highlights a unifying mechanism for recognition of structurally diverse partners. This involves generating similar binding surfaces from entirely different underlying structural elements, large interaction surfaces coupled with extensive redundancy, and side chain conformational plasticity to optimize diverse sets of intermolecular interactions.

Cellular pathways that result in beta cell oxidative stress are poorly resolved. In this study, stimulation of human donor islets, primary mouse islets or homogeneous beta cell lines with a cocktail of inflammatory cytokines (TNF alpha, IL-1 beta, and INF gamma) significantly induced NADPH oxidase-1 (NOX-1) gene expression (p < 0.05). This pro-inflammatory cytokine cocktail concomitantly induced loss of islet glucose stimulated insulin response (p < 0.05), elevated expression of MCP-1 (p < 0.01), increased cellular reactive oxygen species (ROS) and induced cell death. Inhibitors of NADPH oxidase, apocynin and diphenyleneiodonium, and a dual selective NOX1/4 inhibitor, blocked ROS generation (p < 0.01) and induction of MCP-1 (p < 0.05) by pro-inflammatory cytokines in beta cells. It has previously been reported that pro-inflammatory cytokine stimulation induces 12-lipoxygenase (12-LO) expression in human islets. 12-Hydroxyeicosatetraenoic acid (12-HETE), a product of 12-LO activity, stimulated NOX-1 expression in human islets (p < 0.05). A novel selective inhibitor of 12-LO blocked induction of NOX-1 production of ROS and procaspase 3 cleavage by pro-inflammatory cytokines in INS-1 beta cells (p < 0.01). Inhibition was not seen with a structurally related but inactive analog. Importantly, islets from human type 2 diabetic donors have an elevated expression of NOX-1 (p < 0.05). This study describes an integrated pathway in beta cells that links beta cell dysfunction induced by pro-inflammatory cytokines with 12-lipoxygenase and NADPH oxidase (NOX-1) activation. Inhibitors of this pathway may provide a new therapeutic strategy to preserve beta cell mass in diabetes. (c) 2012 Elsevier Ireland Ltd. All rights reserved.

Ancestry biographical scores for seven clusters corresponding to world major geographical regions were obtained using STRUCTURE, based on genotypes of 168 ancestry informative markers (AIMs), for a sample of 1,291 African Americans (AA), European Americans (EA), and Hispanic Americans (HA) along with data from 1,051 HGDP-CEPH 'diversity panel' as a reference. Self-identified ethnicity and family history data, obtained in an interview, were accurate in identifying the individual major ancestry in the AA and the EA samples (approximately 99% and 95%, respectively) but were not useful for the HA sample and could not predict the extent of admixture in any group. The mean proportions of the combined clusters corresponding to European and Middle Eastern populations in the AA sample, revealed by AIMs analysis, were 0.13. The HA subjects, predominantly Puerto Ricans, showed a highly variable hybrid contribution pattern of clusters corresponding to Europe (0.27), Middle East (0.27), Africa (0.20), and Central Asia (0.14). The effect of admixture on allele frequencies is demonstrated for two single-nucleotide polymorphisms (118A > G, 17 C > T) of the mu opioid receptor gene (OPRM1). This study reiterates the importance of AIMs in defining ancestry, especially in admixed populations.

Vaccine challenges include the genetic diversity and mutability of HIV-1 which create a plethora of constantly changing antigens, the structural features of the viral envelope glycoprotein that disguise conserved receptor-binding sites from the immune system, and the presence of carbohydrate moieties that shield potential epitopes from antibodies. Despite these challenges, there has been significant scientific progress in recent years. In 2009, a large-scale clinical trial known as RV144 demonstrated that a HIV-1 vaccine could modestly reduce the incidence of HIV-1 infection. Further, the identification of broadly neutralizing monoclonal antibodies (such as VRC01, a human monoclonal antibody capable of neutralizing over 90% of natural HIV-1 isolates, as well as PG and PGT antibodies that recognize conserved glycopeptide epitopes) has revealed new opportunities for vaccine design. Our ability to understand HIV-1 structure and antibody epitopes at the atomic level, the rapid advance of computational and bioinformatics approaches to immunogen design, and our newly acquired knowledge that it is possible for a vaccine to reduce the risk of HIV-1 infection, have all opened up new and promising pathways towards the development of an urgently needed effective HIV-1 vaccine. This article summarizes challenges to the development of an HIV-1 vaccine, lessons learned from scientific investigation and completed vaccine trials, and promising developments in HIV-1 vaccine design.

Previous studies have demonstrated that CREB is a proto-oncogene whose overexpression promotes cellular proliferation in hematopoietic cells. Transgenic mice that overexpress CREB in myeloid cells develop a myeloproliferative disease with splenomegaly and aberrant myelopoiesis. However, CREB overexpressing mice do not spontaneously develop acute myeloid leukemia. In this study, we used retroviral insertional mutagenesis to identify genes that accelerate leukemia in CREB transgenic mice. Our mutagenesis screen identified several integration sites, including oncogenes Gfi1, Myb, and Ras. The Sox4 transcription factor was identified by our screen as a gene that cooperates with CREB in myeloid leukemogenesis. We show that the transduction of CREB transgenic mouse bone marrow cells with a Sox4 retrovirus increases survival and self-renewal of cells in vitro. Furthermore, leukemic blasts from the majority of acute myeloid leukemia patients have higher CREB, phosphorylated CREB, and Sox 4 protein expression. Sox4 transduction of mouse bone marrow cells results in increased expression of CREB target genes. We also demonstrate that CREB is a direct target of Sox4 by chromatin immunoprecipitation assays. These results indicate that Sox4 and CREB cooperate and contribute to increased proliferation of hematopoietic progenitor cells.

TI WHIM syndrome caused by a single amino acid substitution in the carboxy-tail of chemokine receptor CXCR4 SO BLOOD LA English DT Article ID TERMINUS-TRUNCATED CXCR4; ANTAGONIST PLERIXAFOR; NEUTROPHIL CXCR4; HEALTHY-CHILDREN; CELL SUBSETS; BONE-MARROW; MYELOKATHEXIS; HYPOGAMMAGLOBULINEMIA; INTERNALIZATION; INFECTIONS AB WHIM syndrome is a rare, autosomal dominant, immunodeficiency disorder so-named because it is characterized by warts, hypogammaglobulinemia, infections, and myelokathexis (defective neutrophil egress from the BM). Gain-of-function mutations that truncate the C-terminus of the chemokine receptor CXCR4 by 10-19 amino acids cause WHIM syndrome. We have identified a family with autosomal dominant inheritance of WHIM syndrome that is caused by a missense mutation in CXCR4, E343K (1027G -> A). This mutation is also located in the C-terminal domain, a region responsible for negative regulation of the receptor. Accordingly, like CXCR4(R334X), the most common truncation mutation in WHIM syndrome, CXCR4(E343K) mediated approximately 2-fold increased signaling in calcium flux and chemotaxis assays relative to wild-type CXCR4; however, CXCR4(E343K) had a reduced effect on blocking normal receptor down-regulation from the cell surface. Therefore, in addition to truncating mutations in the C-terminal domain of CXCR4, WHIM syndrome may be caused by a single charge-changing amino acid substitution in this domain, E343K, that results in increased receptor signaling.

TI Circulating IL-15 exists as heterodimeric complex with soluble IL-15R alpha in human and mouse serum SO BLOOD LA English DT Article ID NATURAL-KILLER-CELLS; CD8(+) T-CELLS; MARROW-DERIVED CELLS; TRANS-PRESENTATION; RECEPTOR-ALPHA; IN-VIVO; LYMPHOID HOMEOSTASIS; NONHUMAN-PRIMATES; BETA-CHAIN; INTERLEUKIN-15 AB IL-15 is an important cytokine for the function of the immune system, but the form(s) of IL-15 produced in the human body are not fully characterized. Coexpression of the single-chain IL-15 and the IL-15 receptor alpha (IL-15R alpha) in the same cell allows for efficient production, surface display, and eventual cleavage and secretion of the bioactive IL-15/IL-15R alpha heterodimer in vivo, whereas the single-chain IL-15 is poorly secreted and unstable. This observation led to the hypothesis that IL-15 is produced and secreted only as a heterodimer with IL-15R alpha. We purified human IL-15/IL-15R alpha complexes from overproducing human cell lines and developed an ELISA specifically measuring the heterodimeric form of IL-15. Analysis of sera from melanoma patients after lymphodepletion revealed the presence of circulating IL-15/IL-15R alpha complexes in amounts similar to the total IL-15 quantified by a commercial IL-15 ELISA that detects both the single-chain and the heterodimeric forms of the cytokine. Therefore, in lymphodepleted cancer patients, the serum IL-15 is exclusively present in its heterodimeric form. Analysis of the form of IL-15 present in either normal or lymphodepleted mice agrees with the human data. These results have important implications for development of assays and materials for clinical applications of IL-15.

Many studies suggest protective effects among smokers and for aggressive prostate cancer, however. Methods: We conducted a nested case-control study of serum alpha-tocopherol and gamma-tocopherol and prostate cancer risk in the Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial, with 680 prostate cancer cases and 824 frequency-matched controls. Multivariate-adjusted, conditional logistic regression models were used to estimate odds ratios (OR) and 95% confidence intervals (CIs) for tocopherol quintiles. Results: Serum alpha-tocopherol and gamma-tocopherol were inversely correlated (r = -0.24, p < 0.0001). Higher serum alpha-tocopherol was associated with significantly lower prostate cancer risk (OR for the highest vs. lowest quintile = 0.63, 95% CI 0.44-0.92, p-trend 0.05). By contrast, risk was non-significantly elevated among men with higher gamma-tocopherol concentrations (OR for the highest vs. lowest quintile = 1.35, 95% CI 0.92-1.97, p-trend 0.41). The inverse association between prostate cancer and alpha-tocopherol was restricted to current and recently former smokers, but was only slightly stronger for aggressive disease. By contrast, the increased risk for higher gamma-tocopherol was more pronounced for less aggressive cancers. Conclusions: Our findings indicate higher alpha-tocopherol status is associated with decreased risk of developing prostate cancer, particularly among smokers. Although two recent controlled trials did not substantiate an earlier finding of lower prostate cancer incidence and mortality in response to supplementation with a relatively low dose of a-tocopherol, higher a-tocopherol status may be beneficial with respect to prostate cancer risk among smokers. Determining what stage of prostate cancer development is impacted by vitamin E, the underlying mechanisms, and how smoking modifies the association, is needed for a more complete understanding of the vitamin E-prostate cancer relation.

TI Eltrombopag and Improved Hematopoiesis in Refractory Aplastic Anemia SO NEW ENGLAND JOURNAL OF MEDICINE LA English DT Article ID RABBIT ANTITHYMOCYTE GLOBULIN; IMMUNOSUPPRESSIVE THERAPY; C-MPL; MARROW-TRANSPLANTATION; STIMULATING FACTOR; MICE LACKING; BONE-MARROW; STEM-CELLS; THROMBOPOIETIN; SURVIVAL AB BACKGROUND Severe aplastic anemia, which is characterized by immune-mediated bone marrow hypoplasia and pancytopenia, can be treated effectively with immunosuppressive therapy or allogeneic transplantation. One third of patients have disease that is refractory to immunosuppression, with persistent, severe cytopenia and a profound deficit in hematopoietic stem cells and progenitor cells. Thrombopoietin may increase the number of hematopoietic stem cells and progenitor cells. METHODS We conducted a phase 2 study involving patients with aplastic anemia that was refractory to immunosuppression to determine whether the oral thrombopoietin mimetic eltrombopag (Promacta) can improve blood counts. Twenty-five patients received eltrombopag at a dose of 50 mg, which could be increased, as needed, to a maximum dose of 150 mg daily, for a total of 12 weeks. Primary end points were clinically significant changes in blood counts or transfusion independence. Patients with a response continued to receive eltrombopag. RESULTS Eleven of 25 patients (44%) had a hematologic response in at least one lineage at 12 weeks, with minimal toxic effects. Nine patients no longer needed platelet transfusions (median increase in platelet count, 44,000 per cubic millimeter). Six patients had improved hemoglobin levels (median increase, 4.4 g per deciliter); 3 of them were previously dependent on red-cell transfusions and no longer needed transfusions. Nine patients had increased neutrophil counts (median increase, 1350 per cubic millimeter). Serial bone marrow biopsies showed normalization of trilineage hematopoiesis in patients who had a response, without increased fibrosis. Monitoring of immune function revealed no consistent changes. CONCLUSIONS Treatment with eltrombopag was associated with multilineage clinical responses in some patients with refractory severe aplastic anemia.

CA CKD-EPI Investigators TI Estimating Glomerular Filtration Rate from Serum Creatinine and Cystatin C SO NEW ENGLAND JOURNAL OF MEDICINE LA English DT Article ID CHRONIC KIDNEY-DISEASE; RISK POPULATION COHORTS; COLLABORATIVE METAANALYSIS; HIGHER ALBUMINURIA; ESTIMATING GFR; RENAL-DISEASE; ALL-CAUSE; MORTALITY; EQUATIONS; ASSOCIATION AB BACKGROUND Estimates of glomerular filtration rate (GFR) that are based on serum creatinine are routinely used; however, they are imprecise, potentially leading to the overdiagnosis of chronic kidney disease. Cystatin C is an alternative filtration marker for estimating GFR. METHODS Using cross-sectional analyses, we developed estimating equations based on cystatin C alone and in combination with creatinine in diverse populations totaling 5352 participants from 13 studies. These equations were then validated in 1119 participants from 5 different studies in which GFR had been measured. Cystatin and creatinine assays were traceable to primary reference materials. RESULTS Mean measured GFRs were 68 and 70 ml per minute per 1.73 m(2) of body-surface area in the development and validation data sets, respectively. In the validation data set, the creatinine-cystatin C equation performed better than equations that used creatinine or cystatin C alone. Bias was similar among the three equations, with a median difference between measured and estimated GFR of 3.9 ml per minute per 1.73 m(2) with the combined equation, as compared with 3.7 and 3.4 ml per minute per 1.73 m(2) with the creatinine equation and the cystatin C equation (P = 0.07 and P = 0.05), respectively. Precision was improved with the combined equation (inter-quartile range of the difference, 13.4 vs. 15.4 and 16.4 ml per minute per 1.73 m(2), respectively [P = 0.001 and P<0.001]), and the results were more accurate (percentage of estimates that were >30% of measured GFR, 8.5 vs. 12.8 and 14.1, respectively [P<0.001 for both comparisons]). In participants whose estimated GFR based on creatinine was 45 to 74 ml per minute per 1.73 m(2), the combined equation improved the classification of measured GFR as either less than 60 ml per minute per 1.73 m(2) or greater than or equal to 60 ml per minute per 1.73 m(2) (net reclassification index, 19.4% [P<0.001]) and correctly reclassified 16.9% of those with an estimated GFR of 45 to 59 ml per minute per 1.73 m(2) as having a GFR of 60 ml or higher per minute per 1.73 m(2). CONCLUSIONS The combined creatinine-cystatin C equation performed better than equations based on either of these markers alone and may be useful as a confirmatory test for chronic kidney disease.

Increasing the valency of a mosaic immunogen cocktail increases epitope coverage but with diminishing returns, as increasingly rare epitopes are incorporated into the mosaic proteins. In this study we compared the immunogenicity of 2-valent and 3-valent HIV-1 envelope mosaic immunogens in rhesus monkeys. Immunizations with the 3-valent mosaic immunogens resulted in a modest increase in the breadth of vaccine-elicited T lymphocyte responses compared to the 2-valent mosaic immunogens. However, the 3-valent mosaic immunogens elicited significantly higher neutralizing responses to Tier 1 viruses than the 2-valent mosaic immunogens. These findings underscore the potential utility of polyvalent mosaic immunogens for eliciting both cellular and humoral immune responses to HIV-1. (C) 2012 Elsevier Inc. All rights reserved.

However, only a few studies on alpha-syn have been performed in the mDA neurons in vivo, which may be attributed to a lack of alpha-syn transgenic mice that develop PD-like severe degeneration of mDA neurons. To gain mechanistic insights into the alpha-syn-induced mDA neurodegeneration, we generated a new line of tetracycline-regulated inducible transgenic mice that overexpressed the PD-related alpha-syn A53T missense mutation in the mDA neurons. Here we show that the mutant mice developed profound motor disabilities and robust mDA neurodegeneration, resembling some key motor and pathological phenotypes of PD. We also systematically examined the subcellular abnormalities that appeared in the mDA neurons of mutant mice and observed a profound decrease of dopamine release, the fragmentation of Golgi apparatus, and the impairments of autophagy/lysosome degradation pathways in these neurons. To further understand the specific molecular events leading to the alpha-syn-dependent degeneration of mDA neurons, we found that overexpression of alpha-syn promoted a proteasome-dependent degradation of nuclear receptor-related 1 protein (Nurr1), whereas inhibition of Nurr1 degradation ameliorated the alpha-syn-induced loss of mDA neurons. Given that Nurr1 plays an essential role in maintaining the normal function and survival of mDA neurons, our studies suggest that the alpha-syn-mediated suppression of Nurr1 protein expression may contribute to the preferential vulnerability of mDA neurons in the pathogenesis of PD.

Serotonin 2C (5-HT2C) receptors mediate the inhibitory effects of serotonin on dopaminergic circuitry in experimental animals, and preclinical findings have implicated 5-HT2C receptors in motivated behaviors and psychotropic drug mechanisms. In humans, a common missense single-nucleotide change (rs6318, Cys23Ser) in the 5-HT2C receptor gene (HTR2C) has been associated with altered activity in vitro and with clinical mood disorders. We hypothesized that dopaminergic circuitry would be more sensitive to stress in humans carrying the Ser23 variant. To test this hypothesis, we studied 54 healthy humans using positron emission tomography and the displaceable D-2/D-3 receptor radiotracer [C-11]raclopride. Binding potential (BPND) was quantified before and after a standardized stress challenge consisting of 20 min of moderate deep muscular pain, and reduction in BPND served as an index of dopamine release. The Cys23Ser variant was genotyped on a custom array, and ancestry informative markers were used to control for population stratification. We found greater dopamine release in the nucleus accumbens, caudate nucleus, and putamen among Ser23 carriers, after controlling for sex, age, and ancestry. Genotype accounted for 12% of the variance in dopamine release in the nucleus accumbens. There was no association of Cys23Ser with baseline BPND. These findings indicate that a putatively functional HTR2C variant (Ser23) is associated with greater striatal dopamine release during pain in healthy humans. Mesoaccumbal stress sensitivity may mediate the effects of HTR2C variation on risk of neuropsychiatric disorders.

TI Evidence for Helical Structure in a Tetramer of alpha 2-8 Sialic Acid: Unveiling a Structural Antigen SO JOURNAL OF THE AMERICAN CHEMICAL SOCIETY LA English DT Article ID B MENINGOCOCCAL POLYSACCHARIDE; NEISSERIA-MENINGITIDIS; HYDROGEN-BONDS; SCALAR COUPLINGS; AQUEOUS-SOLUTION; BASE-PAIRS; NMR; PROTEINS; SPECTROSCOPY; EXCHANGE AB Characteristic H-bonding patterns define secondary structure in proteins and nucleic acids. We show that similar patterns apply for alpha 2-8 sialic acid (SiA) in H2O and that H-bonds define its structure. A N-15,C-13 alpha 2-8 SiA tetramer, (SiA)(4), was used as a model system for the polymer. At 263 K, we detected intra-residue through-H-bond J couplings between N-15 and C8 for residues R-I-R-III of the tetramer, indicating H-bonds between the N-15's and the O8's of these residues. Additional J couplings between the N-15's and C2's of the adjacent residues confirm the putative H-bonds. NH groups showing this long-range correlation also experience slower H-1/H-2 exchange. Additionally, detection of couplings between H7 and C2 for R-II and R-III implies that the conformations of the linkers between these residues are different than in the monomers. These structural elements are consistent with two left-handed helical models: 2 residues/turn (2(4) helix) and 4 residues/turn (1(4) helix). To discriminate between models, we resorted to H-1,H-1 NOEs. The 2(4) helical model is in better agreement with the experimental data. We provide direct evidence of H-bonding for (SiA)(4) and show how H-bonds can be a determining factor for shaping its 3D structure.

None of the compounds were mutagenic in the Salmonella/Escherichia coli/microsome plate incorporation test. CP-31398 and SHetA2 did not induce chromosomal aberrations (CA) in Chinese hamster ovary (CHO) cells, either in the presence or absence of rat hepatic 59(59). PI induced CA in CHO cells, but only in the presence of S9. PI, its parent compound ibuprofen, and its moiety diethoxyphosphoryloxybutyl alcohol (DEPBA) were tested for CA and micronuclei (MN) in CHO cells in the presence of S9. PI induced CA as well as MN, both kinetochore-positive (Kin+) and -negative (Kin-), in the presence of S9 at <= 100 mu g/ml. Ibuprofen was negative for CA, positive for MN with Kin+ at 250 mu g/ml, and positive for MN with Kin - at 125 and 250 mu g/ml. DEPBA induced neither CA nor MN at <= 5000 mu g/ml. The induction of chromosomal damage in PI-treated CHO cells in the presence of S9 may be due to its metabolites. None of the compounds were genotoxic, in the presence or absence of S9, in the GADD45 alpha-GFP Human GreenScreen assay and none induced MN in mouse bone marrow erythrocytes. (C) 2012 Elsevier B.V.

However, whereas sporadic translocations decapitate Myc from 5' proximal regulatory elements, most endemic events occur hundreds of kilobases away from Myc. The origin of these rearrangements and how they deregulate oncogenes at such distances remain unclear. We here recapitulate endemic Burkitt lymphoma-like translocations in plasmacytomas from uracil N-glycosylase and activation-induced cytidine deaminase-deficient mice. Mapping of translocation breakpoints using an acetylated histone H3 lysine 9 chromatin immunoprecipitation sequencing approach reveals Igh fusions up to similar to 350 kb upstream of Myc or the related oncogene Mycn. A comprehensive analysis of epigenetic marks, PolII recruitment, and transcription in tumor cells demonstrates that the 3' Igh enhancer (Ea) vastly remodels similar to 450 kb of chromatin into translocated sequences, leading to significant polymerase occupancy and constitutive oncogene expression. We show that this long-range epigenetic reprogramming is directly proportional to the physical interaction of E alpha with translocated sites. Our studies thus uncover the extent of epigenetic remodeling by Ig 3' enhancers and provide a rationale for the long-range deregulation of translocated oncogenes in endemic Burkitt lymphomas. The data also shed light on the origin of endemic-like chromosomal rearrangements. C1 [Nussenzweig, Michel C.] Rockefeller Univ, Lab Mol Immunol, New York, NY 10065 USA.

In an attempt to identify additional T2D genes, we analyzed global gene expression in human islets from 63 donors. Using 48 genes located near T2D risk variants, we identified gene coexpression and protein-protein interaction networks that were strongly associated with islet insulin secretion and HbA(1c). We integrated our data to form a rank list of putative T2D genes, of which CHL1, LRFN2, RASGRP1, and PPM1K were validated in INS-1 cells to influence insulin secretion, whereas GPR120 affected apoptosis in islets. Expression variation of the top 20 genes explained 24% of the variance in HbA(1c) with no claim of the direction. The data present a global map of genes associated with islet dysfunction and demonstrate the value of systems genetics for the identification of genes potentially involved in T2D.

They contain C-terminal extracellular passenger domains that are involved in adhesion to host cells and N-terminal 6 domains that are embedded in the outer membrane. Here, we identify the domain boundaries of an E. coli intimin beta domain and use this information to solve its structure and the beta domain structure of a Y. pseudotuberculosis invasin. Both beta domain structures crystallized as monomers and reveal that the previous range of residues assigned to the beta domain also includes a protease-resistant domain that is part of the passenger. Additionally, we identify 146 nonredundant representative members of the intimin/invasin family based on the boundaries of the highly conserved intimin and invasin beta domains. We then use this set, of sequences along with our structural data to find and map the evolutionarily constrained residues within the beta domain.

TI Nitrite Reductase Activity of Nonsymbiotic Hemoglobins from Arabidopsis thaliana SO BIOCHEMISTRY LA English DT Article ID PLANT HEMOGLOBINS; NITRATE REDUCTASE; OXIDE BIOACTIVITY; GENE-EXPRESSION; IN-VIVO; NO; AFFINITY; ROOTS; DEOXYHEMOGLOBIN; METABOLISM AB Plant nonsymbiotic hemoglobins possess hexacoordinate heme geometry similar to that of the heme protein neuroglobin. We recently discovered that deoxygenated neuroglobin converts nitrite to nitric oxide (NO), an important signaling molecule involved in many processes in plants. We sought to determine whether Arabidopsis thaliana nonsymbiotic hemoglobins classes 1 and 2 (AHb1 and AHb2, respectively) might function as nitrite reductases. We found that the reaction of nitrite with deoxygenated AHb1 and AHb2 generates NO gas and iron-nitrosyl-hemoglobin species. The bimolecular rate constants for reduction of nitrite to NO are 19.8 +/- 3.2 and 4.9 +/- 0.2 M-1 s(-1), respectively, at pH 7.4 and 25 degrees C. We determined the pH dependence of these bimolecular rate constants and found a linear correlation with the concentration of protons, indicating the requirement for one proton in the reaction. The release of free NO gas during the reaction under anoxic and hypoxic (2% oxygen) conditions was confirmed by chemiluminescence detection. These results demonstrate that deoxygenated AHb1 and AHb2 reduce nitrite to form NO via a mechanism analogous to that observed for hemoglobin, myoglobin, and neuroglobin. Our findings suggest that during severe hypoxia and in the anaerobic plant roots, especially in species submerged in water, nonsymbiotic hemoglobins provide a viable pathway for NO generation via nitrite reduction.

TI From Hot Hands to Declining Effects SO JOURNAL OF THE AMERICAN COLLEGE OF CARDIOLOGY LA English DT Editorial Material DE numbers; outcomes assessment; quality ID DECOMPENSATED HEART-FAILURE; RANDOMIZED-TRIAL; CLINICAL-TRIAL; NESIRITIDE; METAANALYSIS; CAPTOPRIL; LOSARTAN; ELITE AB About 25 years ago, a group of researchers demonstrated that there is no such thing as the "hot hand" in professional basketball. When a player hits 5 or 7 shots in a row (or misses 10 in a row), what's at work is random variation, nothing more. However, random causes do not stop players, coaches, fans, and media from talking about and acting on "hot hands," telling stories and making choices that ultimately are based on randomness. The same phenomenon is true in medicine. Some clinical trials with small numbers of events yielded positive findings, which in turn led clinicians, academics, and government officials to talk, telling stories and sometimes making choices that were later shown to be based on randomness. I provide some cardiovascular examples, such as the use of angiotensin receptor blockers for chronic heart failure, nesiritide for acute heart failure, and cytochrome P-450 (CYP) 2C19 genotyping for the acute coronary syndromes. I also review the more general " decline effect," by which drugs appear to yield a lower effect size over time. The decline effect is due at least in part to over interpretation of small studies, which are more likely to be noticed because of publication bias. As funders of research, we at the National Heart, Lung, and Blood Institute seek to support projects that will yield robust, credible evidence that will affect practice and policy in the right way. We must be alert to the risks of small numbers.

These potential indications are supported by strong preliminary data from multiple investigators using diverse preclinical models. However, clinical trials for CB2 agonists, when they have been reported have generally been disappointing. This review considers possible explanations for the mismatch between promising preclinical data and disappointing clinical data. We propose that a more careful consideration of CB2 receptor pharmacology may help move CB2 agonists from "promising" to "effective" therapeutics. (C) 2012 Elsevier Inc. All rights reserved.

Significant progress in the discovery of novel therapeutic agents has been made in the past few years. While sipuleucel-T, cabazitaxel, and abiraterone gained regulatory approval in 2010 and 2011, several highly promising candidates/regimens have failed in large scale clinical trials. Challenges remain to optimize the design and interpretation of clinical trial results and develop more effective strategies for mCRPC. In this review, we examined the positive and negative clinical trials in mCRPC in the past and discussed the various aspects of clinical trial design including selection of targets and appropriate outcome measures, biomarker development and implementation, and strategies for combination therapy.

All proliferative islets expressed synaptophysin, although decreased expression intensity was observed in hyperplasias and adenomas. Most of the proliferative lesions expressed insulin, which generally decreased as lesions progressed toward malignancy. The distribution of glucagon, somatostatin, and gastrin-expressing cells was altered in proliferative islet lesions but did not comprise a large proportion of cells. Islet cell tumors were associated with increased nuclear expression of cyclin-dependent kinase 4 as well as increased proliferating cell nuclear antigen and decreased beta-catenin expression. c-Myelocytomatosis oncogene expression was variable. This is the first study to describe the immunophenotype of islet cell tumors in the F344 rat and to show that islet cell tumors in the F344 rat exhibit similarities in protein expression to the human counterpart.

TI TIL therapy broadens the tumor-reactive CD8(+) T cell compartment in melanoma patients SO ONCOIMMUNOLOGY LA English DT Article DE tumor immunology; TIL therapy; high throughput screening; pMHC multiplexing; T-cell reactivity ID METASTATIC MELANOMA; INFILTRATING LYMPHOCYTES; ADOPTIVE TRANSFER; RESPONSES; CANCER; TRANSPLANTATION; IMMUNOTHERAPY; GENERATION; MUTATION; DESIGN AB There is strong evidence that both adoptive T cell transfer and T cell checkpoint blockade can lead to regression of human melanoma. However, little data are available on the effect of these cancer therapies on the tumor-reactive T cell compartment. To address this issue we have profiled therapy-induced T cell reactivity against a panel of 145 melanoma-associated CD8(+) T cell epitopes. Using this approach, we demonstrate that individual tumor-infiltrating lymphocyte cell products from melanoma patients contain unique patterns of reactivity against shared melanoma-associated antigens, and that the combined magnitude of these responses is surprisingly low. Importantly, TIL therapy increases the breadth of the tumor-reactive T cell compartment in vivo, and T cell reactivity observed post-therapy can almost in full be explained by the reactivity observed within the matched cell product. These results establish the value of high-throughput monitoring for the analysis of immuno-active therapeutics and suggest that the clinical efficacy of TIL therapy can be enhanced by the preparation of more defined tumor-reactive T cell products.

TI Two distinct sites in Nup153 mediate interaction with the SUMO proteases SENP1 and SENP2 SO NUCLEUS LA English DT Article DE SENP1; SENP2; Nup153; SUMO modification; nuclear pore complex ID NUCLEAR-PORE COMPLEX; DESUMOYLATING ENZYMES; NUCLEOPORIN NUP153; SUMOYLATION; ISOPEPTIDASE; SPECIFICITY; KARYOPHERINS; MECHANISMS; MITOSIS; PATHWAY AB Numerous enzymes of the mammalian SUMO modification pathway, including two members of the SUMO protease family, SENP2 and SENP1, localize to the nuclear periphery. The SUMO proteases play roles both in processing SUMO during the biogenesis of this peptide moiety and also in reversing SUMO modification on specific targets to control the activities conferred by this post-translational modification. Although interaction with the C-terminal domain of the nucleoporin Nup153 is thought to contribute to SENP2 localization at the nuclear pore complex, little is known about the binding partners of SENP1 at the nuclear periphery. We have found that Nup153 binds to both SENP1 and SENP2 and does so by interacting with the unique N-terminal domain of Nup153 as well as a specific region within the C-terminal FG-rich region. We have further found that Nup153 is a substrate for sumoylation, with this modification kept in check by these two SUMO proteases. Specifically, either RNAi depletion of SENP1/SENP2 or expression of dominantly interfering mutants of these proteins results in increased sumoylation of endogenous Nup153. While SENP1 and SENP2 share many characteristics, we show here that SENP1 levels are influenced by the presence of Nup153, whereas SENP2 is not sensitive to changes in Nup153 abundance.

TI Withholding response in the face of a smile: Age-related differences in prefrontal sensitivity to Nogo cues following happy and angry faces SO DEVELOPMENTAL COGNITIVE NEUROSCIENCE LA English DT Article DE Emotion; Cognition-emotion interactions; fMRI; Control; Development ID FACIAL-EMOTION RECOGNITION; ORBITOFRONTAL CORTEX; COGNITIVE CONTROL; BASOLATERAL AMYGDALA; BRAIN; CHILDHOOD; BEHAVIOR; ADOLESCENCE; INHIBITION; ATTENTION AB The modulation of control processes by stimulus salience, as well as associated neural activation, changes over development. We investigated age-related differences in the influence of facial emotion on brain activation when an action had to be withheld, focusing on a developmental period characterized by rapid social-emotional and cognitive change. Groups of kindergarten and young school-aged children and a group of young adults performed a modified Go/Nogo task. Response cues were preceded by happy or angry faces. After controlling for task performance, left orbitofrontal regions discriminated trials with happy vs. angry faces in children but not in adults when a response was withheld, and this effect decreased parametrically with age group. Age-related changes in prefrontal responsiveness to facial expression were not observed when an action was required, nor did this region show age-related activation changes with the demand to withhold a response in general. Such results reveal age-related differences in prefrontal activation that are specific to stimulus valence and depend on the action required. (C) 2012 Elsevier Ltd. All rights reserved.

Scott TI Feasibility and Pilot Efficacy Results From the Multisite Cognitive Remediation in the Schizophrenia Trials Network (CRSTN) Randomized Controlled Trial SO JOURNAL OF CLINICAL PSYCHIATRY LA English DT Article ID NEUROCOGNITIVE DEFICITS; THERAPY; METAANALYSIS; ADULTS AB Background: The true benefit of pharmacologic intervention to improve cognition in schizophrenia may not be evident without regular cognitive enrichment. Clinical trials assessing the neurocognitive effects of new medications may require engagement in cognitive remediation exercises to stimulate the benefit potential. However, the feasibility of large-scale multisite studies using cognitive remediation at clinical trials sites has not been established. Method: 53 adult patients with DSM-IV schizophrenia from 9 university-affiliated sites were randomized to a cognitive remediation condition that included the Posit Science Brain Fitness auditory training program with weekly Neuropsychological and Educational Approach to Remediation (NEAR) "bridging groups" or a control condition of computer games and weekly healthy lifestyles groups. Patients were expected to complete 3 to 5 one-hour sessions weekly for 40 sessions or 12 weeks, whichever came first. The primary outcomes were feasibility results as measured by rate of enrollment, retention, and completion rate of primary outcome measures. The study was conducted from July 2009 through January 2010. Results: During a 3-month enrollment period, 53 (of a projected 54) patients were enrolled, and 41 (77%) met criteria for study completion. Thirty-one patients completed all 40 sessions, and all patients completed all primary outcome measures. Preliminary efficacy results indicated that, after 20 sessions, patients in the cognitive remediation condition demonstrated mean MATRICS Consensus Cognitive Battery composite score improvements that were 3.7(95% CI, 0.05-7.34) T-score points greater than in patients in the computer-games control group (F-1,F-46=4.16, P=.047). At the end of treatment, a trend favoring cognitive remediation was not statistically significant (F-1,F-47=2.26, P=.14). Conclusion: Multisite clinical trials of cognitive remediation using the Posit Science Brain Fitness auditory training program with the NEAR method of weekly bridging groups at traditional clinical sites appear to be feasible.

Many of these models were developed in parallel and iteratively with experimental studies and provided predictions guiding new experiments. This data-driven modeling approach has advanced our understanding of respiratory network architecture and neural mechanisms underlying generation of the respiratory rhythm and pattern, including their functional reorganization under different physiological conditions. Models reviewed here vary in neurobiological details and computational complexity and span multiple spatiotemporal scales of respiratory control mechanisms. Recent models describe interacting populations of respiratory neurons spatially distributed within the Botzinger and pre-Botzinger complexes and rostral ventrolateral medulla that contain core circuits of the respiratory central pattern generator (CPG). Network interactions within these circuits along with intrinsic rhythmogenic properties of neurons form a hierarchy of multiple rhythm generation mechanisms. The functional expression of these mechanisms is controlled by input drives from other brainstem components, including the retrotrapezoid nucleus and pons, which regulate the dynamic behavior of the core circuitry. The emerging view is that the brainstem respiratory network has rhythmogenic capabilities at multiple levels of circuit organization. This allows flexible, state-dependent expression of different neural pattern-generation mechanisms under various physiological conditions, enabling a wide repertoire of respiratory behaviors. Some models consider control of the respiratory CPG by pulmonary feedback and network reconfiguration during defensive behaviors such as cough. Future directions in modeling of the respiratory CPG are considered. Published 2012 Compr Physiol 2:1619-1670, 2012.

Among the early innate immune effector cells, dendritic cells (DCs) respond rapidly following infection aimed at arming the immune system, through the recognition of viral products via pattern recognition receptors. This early response results in the potent induction of a cascade of inflammatory cytokines, intimately involved in directly setting up an antiviral state, and indirectly activating other antiviral cells of the innate immune system. However, epidemiologic data strongly support a role for natural killer (NK) cells as critical innate mediators of antiviral control, through the recognition of virally infected cells through a network of receptors called the killer immunoglobulin-like receptors (KIRs). In this review, the earlyevents in innate immune recognition of HIV, focused on defining the biology underlying KIR-mediated NK-cell control of HIV viral replication, are discussed.

The first is reverse transcription, which results in the production of a double-stranded DNA copy of the viral RNA genome, and the second is integration, which results in covalent attachment of the DNA copy to host cell DNA. The initial catalytic steps of the integration reaction are performed by the virus-encoded integrase (IN) protein. The chemistry of the IN-mediated DNA breaking and joining steps is well worked out, and structures of IN-DNA complexes have now clarified how the overall complex assembles. Methods developed during these studies were adapted for identification of IN inhibitors, which received FDA approval for use in patients in 2007. At the chromosomal level, HIV integration is strongly favored in active transcription units, which may promote efficient viral gene expression after integration. HIV IN binds to the cellular factor LEDGF/p75, which promotes efficient infection and tethers IN to favored target sites. The HIVintegration machinery must also interact with many additional host factors during infection, including nuclear trafficking and pore proteins during nuclear entry, histones during initial target capture, and DNA repair proteins during completion of the DNA joining steps. Models for some of the molecular mechanisms involved have been proposed, but important details remain to be clarified. C1 [Craigie, Robert] NIDDK, Mol Virol Sect, NIH, Bethesda, MD 20892 USA.

The Role of Processed Foods in Achieving Dietary Guidelines and Nutrient Recommendations in the U.S." describes ongoing efforts and challenges at the nutrition food science interface and public health; addresses misinformation about processed foods by showing that processed fruits and vegetables made important dietary contributions (e.g., fiber, folate, potassium, vitamins A and C) to nutrient intake among NHANES 2003-2006 participants, that major sources of vitamins (except vitamin K) were provided by enrichment and fortification and that enrichment and fortification helped decrease the percentage of the population below the Estimated Average Requirement for vitamin A, thiamin, folate, and iron; describes how negative consumer perceptions and consumer confusion about processed foods led to the development of science-based information on food processing and technology that aligns with health objectives; and examines challenges and opportunities faced by food scientists who must balance consumer preferences, federal regulations, and issues surrounding food safety, cost, unintended consequences, and sustainability when developing healthful foods that align with dietary guidelines.

Iron supplementation has been shown to increase malaria risk in these groups in numerous studies, although this effect is likely diminished by factors such as host immunity, host iron status, and effective malaria surveillance and control. Conversely, the risk of anemia is increased by malaria infections and preventive measures against malaria decrease anemia prevalence in susceptible populations without iron supplementation. Studies have shown that subjects with malaria experience diminished absorption of orally administered iron, so that as a consequence, iron supplementation may have generally reduced efficacy in malarious populations. A possible mechanistic link between malaria, poor absorption of iron, and anemia is provided by recent research on hepcidin, the human iron control hormone. Our improved understanding of iron metabolism may contribute to the control of malaria and the treatment of anemia. Malaria surveillance and control are necessary components of programs to control iron deficiency and may enhance the efficacy of iron supplementation. Adv. Nutr. 3: 570-578, 2012.

TI Normal Left Ventricular Myocardial Thickness for Middle-Aged and Older Subjects With Steady-State Free Precession Cardiac Magnetic Resonance The Multi-Ethnic Study of Atherosclerosis SO CIRCULATION-CARDIOVASCULAR IMAGING LA English DT Article DE magnetic resonance imaging; myocardial thickness; normal values ID FAST GRADIENT-ECHO; COMPUTED-TOMOGRAPHY; BODY-SIZE; MASS; POPULATION; GENDER; HEART; MRI; QUANTIFICATION; DIMENSIONS AB Background-Increased left ventricular myocardial thickness (LVMT) is a feature of several cardiac diseases. The purpose of this study was to establish standard reference values of normal LVMT with cardiac magnetic resonance and to assess variation with image acquisition plane, demographics, and left ventricular function. Methods and Results-End-diastolic LVMT was measured on cardiac magnetic resonance steady-state free precession cine long and short axis images in 300 consecutive participants free of cardiac disease (169 women; 65.6 +/- 8.5 years) of the Multi-Ethnic Study of Atherosclerosis cohort. Mean LVMT on short axis images at the mid-cavity level was 5.3 +/- 0.9 mm and 6.3 +/- 1.1 mm for women and men, respectively. The average of the maximum LVMT at the mid-cavity for women/men was 7/9 mm (long axis) and 7/8 mm (short axis). Mean LVMT was positively associated with weight (0.02 mm/kg; P=0.01) and body surface area (1.1 mm/m(2); P<0.001). No relationship was found between mean LVMT and age or height. Greater mean LVMT was associated with lower left ventricular end-diastolic volume (0.01 mm/mL; P<0.01), a lower left ventricular end-systolic volume (-0.01 mm/mL; P=0.01), and lower left ventricular stroke volume (-0.01 mm/mL; P<0.05). LVMT measured on long axis images at the basal and mid-cavity level were slightly greater (by 6% and 10%, respectively) than measurements obtained on short axis images; apical LVMT values on long axis images were 20% less than those on short axis images.

TI Lifetime Analysis of Hospitalizations and Survival of Patients Newly Admitted With Heart Failure SO CIRCULATION-HEART FAILURE LA English DT Article DE heart failure; hospital readmission; cardiovascular diseases; myocardial ischemia; epidemiology; health services research; prognosis; population ID LEFT-VENTRICULAR DYSFUNCTION; EJECTION FRACTION; MEDICARE BENEFICIARIES; COMMUNITY PERSPECTIVE; OUTCOMES; RISK; READMISSION; POPULATION; GENDER; DEATH AB Background-Hospital readmissions for heart failure (HF) contribute to increased morbidity and resource burden. Predictors of hospitalization and patterns of cardiovascular events over the lifetime of patients with HF have not been elucidated. Methods and Results-We examined recurrent hospitalizations, cardiovascular events, and survival among newly discharged (April 1999-March 2001) patients with HF in the Enhanced Feedback For Effective Cardiac Treatment phase 1 study. During 10-year follow-up, we examined all new cardiovascular hospitalizations and selected predictors of readmission. Among 8543 patients (mean age, 77.4 +/- 10.5 years; 51.6% women) followed for 22 567 person-years, 60.7% had ischemic etiology, and 67.3% had HF with reduced ejection fraction (left ventricular ejection fraction <= 45% versus >45% [HF with preserved ejection fraction]). Overall, 10-year mortality was 98.8%, with 35 966 hospital readmissions occurring over the lifetime of the cohort. Adjusted hazards ratios (HRs) for first cardiovascular hospitalization were 1.36 for ischemic HF (95% CI, 1.28-1.44; P<0.001), 1.10 for HF with reduced ejection fraction (95% CI; 1.00-1.20; P=0.045), and 1.00 for men (95% CI, 0.94-1.06; P=0.979). On repeated-events time-to-event analysis, ischemic HF was a predictor of cardiovascular (HR, 1.24; 95% CI, 1.18-1.29), HF (HR, 1.20; 95% CI, 1.13-1.27), and coronary heart disease (HR, 2.01; 95% CI, 1.81-2.24) hospitalizations (all P<0.001). Of all recurrent HF hospitalizations, 26.8% occurred in the first and 39.8% in the last deciles of cohort survival duration. Similarly, 29.7% and 52.3% of all cardiovascular readmissions occurred in the first and last deciles of the cohort survival duration, respectively. Conclusions-Among newly discharged patients with HF, cardiovascular events were clustered at early postdischarge and prefatal time periods, and were increased among those with ischemic etiology.

We examined the external validity of existing HF risk scores, optimized a 10-year HF risk function, and examined the incremental value of several biomarkers, including N-terminal pro-brain natriuretic peptide. Methods and Results-During 15.5 years (210 102 person-years of follow-up), 1487 HF events were recorded among 13 555 members of the biethnic Atherosclerosis Risk in Communities (ARIC) Study cohort. The area under curve from the Framingham-published, Framingham-recalibrated, Health ABC HF recalibrated, and ARIC risk scores were 0.610, 0.762, 0.783, and 0.797, respectively. On addition of N-terminal pro-brain natriuretic peptide, the optimism-corrected area under curve of the ARIC HF risk score increased from 0.773 (95% CI, 0.753-0.787) to 0.805 (95% CI, 0.792-0.820). Inclusion of N-terminal pro-brain natriuretic peptide improved the overall classification of recalibrated Framingham, recalibrated Health ABC, and ARIC risk scores by 18%, 12%, and 13%, respectively. In contrast, cystatin C or high-sensitivity C-reactive protein did not add toward incremental risk prediction. Conclusions-The ARIC HF risk score is more parsimonious yet performs slightly better than the extant risk scores in predicting 10-year risk of incident HF. The inclusion of N-terminal pro-brain natriuretic peptide markedly improves HF risk prediction. A simplified risk score restricted to a patient's age, race, sex, and N-terminal pro-brain natriuretic peptide performs comparably to the full score (area under curve, 0.745) and is suitable for automated reporting from laboratory panels and electronic medical records.

TI Cannabinoid facilitation of behavioral and biochemical hedonic taste responses SO NEUROPHARMACOLOGY LA English DT Article DE Cannabis; Taste; Hedonic; Aversive; Dopamine; Microdialysis; Nucleus accumbens ID NUCLEUS-ACCUMBENS SHELL; FOOD-INTAKE; RECEPTOR ANTAGONIST; DOPAMINE TRANSMISSION; REACTIVITY TEST; IN-VIVO; EXTRACELLULAR DOPAMINE; MOTIVATIONAL STIMULUS; GUSTATORY STIMULI; PREFRONTAL CORTEX AB Cannabinoid receptor agonists are known to stimulate feeding in humans and animals and this effect is thought to be related to an increase in food palatability. On the other hand, highly palatable food stimulates dopamine (DA) transmission in the shell of the nucleus accumbens (NAc) and this effect undergoes one trial habituation. In order to investigate the relationship between the affective properties of tastes and the response of NAc shell DA we studied the effect of delta-9-tetrahydrocannabinol (THC) on behavioral taste reactivity to intraoral infusion of appetitive (sucrose solutions) and aversive (quinine and saturated NaCl solutions) tastes and on the response of in vivo DA transmission in the NAc shell to intraoral sucrose. Rats were implanted with intraoral cannulae and the effect of systemic administration of THC on the behavioral reactions to intraoral infusion of sucrose and of quinine or saturated NaCl solutions were scored. THC increased the hedonic reactions to sucrose but did not affect the aversive reactions to quinine and NaCl. The effects of THC were completely blocked by the CB1 receptor inverse agonist/antagonist rimonabant given at doses that do not affect taste reactivity to sucrose. In rats implanted with microdialysis probes and with intraoral cannulae, THC, made sucrose effective in raising dialysate DA in the shell of the NAc. As in the case of highly palatable food (Fonzies, sweet chocolate), the stimulatory effect of sucrose on shell DA under THC underwent one trial habituation. Altogether, these findings demonstrate that stimulation of CB1 receptors specifically increases the palatability of hedonic taste without affecting that of aversive tastes. Consistent with the ability of THC to increase sucrose palatability is the observation that under THC pretreatment sucrose acquires the ability to induce a release of DA in the shell of the NAc and this property undergoes adaptation after repeated exposure to the taste (habituation).

Supplementation with high-DHA mixture of LD-1227 was applied for 30 days to stress model rats. Both supplementations significantly mitigated the histological brain damage when analyzing hippocampal subregions and corticosterone level. However, LD-1227 was most significantly efficient in preventing SOD, Catalase and ascorbic acid decrease in brain tissue. Both supplementations stimulated neurogenesis in vitro and neuron markers in particular but og olygodendrocyte markers and glia increased only in LD-1227-enriched medium. Taken together, these data suggest that LD-1227 is able to significantly protect the brain structure redox system to higher degree than DHA. Moreover, from in vitro study it appears that marine bioactive compound, through it wide array of small unsaturated fatty acids, phospholipids and neurotransmitter precursors, is likely to influence neuronal and glial lineage to act differently from a DHA-rich mixture.

TI BENEFICIAL EFFECT OF A STURGEON-BASED BIOACTIVE COMPOUND ON GENE EXPRESSION OF TUMOR NECROSIS FACTOR-alpha, MATRIX METALLOPROTEINASES AND TYPE-10 COLLAGEN IN HUMAN CHONDROCYTES SO JOURNAL OF BIOLOGICAL REGULATORS AND HOMEOSTATIC AGENTS LA English DT Article DE osteoarthritis; chondhrocyte; LD-1227; IL beta-stimulation; marine biology compound ID ARTICULAR-CARTILAGE; OSTEOARTHRITIS; INTERLEUKIN-1; EPIDEMIOLOGY; MODULATION; ARTHRITIS AB In the present study, we examined the effect of a marine bioactive compound containing high-purity caviar-derived DNA, collagen elastin and protein extracts from sturgeon (LD-1227, Caviarlieri, Laboratoires Dom, Switzerland) on IL beta -induced activation and production of TNF alpha and MMP-13 in human osteo-arthritis (OA) chondrocytes and intracellular signaling factors. Human chondrocytes were derived from OA cartilage and stimulated with IL beta. Gene expression of TNF alpha, MMP-13, MMP-1 and Col10A1 was measured by quantitative RT-PCR. TNF alpha protein in culture medium was determined using cytokine-specific ELISA. Western immunoblotting was used to analyze the MMP-13 production in the culture medium and the activation of NF-kappa B. DNA binding activity of NF-kappa B p65 was determined using a highly sensitive and specific ELISA. MMP-13 activity in the culture medium was assayed by gelatine zymography. LD-1227 significantly decreased IL beta-stimulated gene expression and production of TNF alpha, MMP-1, MMP-13 and Col10A1 in human chondrocytes. The inhibitory effect of LD-1227 on the IL beta-induced expression of these genes was mediated at least in part via suppression of NF-kappa B p65. These data show that LD-1227 can inhibit IL-1 beta-induced proliferation and inflammatory reactions via inhibited activation of the transcription factor NF-kappa B pathway in human chondrocytes derived from OA patients. These novel pharmacological actions of LD-1227 on IL beta-stimulated human OA chondrocytes provide suggestions that this marine biology compound may inhibit cartilage degradation by suppressing IL beta-mediated activation and the catabolic response in human chondrocytes.

Here, we report that selective endogenous cholinergic activation achieved via in vitro optogenetic stimulation of nucleus accumbens, a terminal field of dopaminergic neurons, elicits real-time dopamine release. This mechanismoccurs via direct actions on dopamine terminals, does not require changes in neuron firing within the midbrain, and is dependent on glutamatergic receptor activity. More importantly, we demonstrate that in vivo selective activation of cholinergic interneurons is sufficient to elicit dopamine release in the nucleus accumbens. Therefore, the control of accumbal extracellular dopamine levels by endogenous cholinergic activity results from a complex convergence of neurotransmitter/neuromodulator systems that may ultimately synergize to drive motivated behavior.

While the "signaling endosomes" hypothesis is one of the accepted models, the molecular machinery that drives retrograde axonal transport of TrkB signaling endosomes is largely unknown. In particular, mechanisms recruiting dynein to TrkB signaling endosomes have not been elucidated. Here, using snapin deficient mice and gene rescue experiments combined with compartmentalized cultures of live cortical neurons, we reveal that Snapin, as a dynein adaptor, mediates retrograde axonal transport of TrkB signaling endosomes. Such a role is essential for dendritic growth of cortical neurons. Deleting snapin or disrupting Snapin-dynein interaction abolishes TrkB retrograde transport, impairs BDNF-induced retrograde signaling from axonal terminals to the nucleus, and decreases dendritic growth. Such defects were rescued by reintroducing the snapin gene. Our study indicates that Snapin-dynein coupling is one of the primary mechanisms driving BDNF-TrkB retrograde transport, thus providing mechanistic insights into the regulation of neuronal growth and survival.

Lytic infection of oligodendrocytes in the brain leads to their eventual destruction and progressive demyelination, resulting in multiple foci of lesions in the white matter of the brain. Before the mid-1980s, PML was a relatively rare disease, reported to occur primarily in those with underlying neoplastic conditions affecting immune function and, more rarely, in allograft recipients receiving immunosuppressive drugs. However, with the onset of the AIDS pandemic, the incidence of PML has increased dramatically. Approximately 3 to 5% of HIV-infected individuals will develop PML, which is classified as an AIDS-defining illness. In addition, the recent advent of humanized monoclonal antibody therapy for the treatment of autoimmune inflammatory diseases such as multiple sclerosis (MS) and Crohn's disease has also led to an increased risk of PML as a side effect of immunotherapy. Thus, the study of JCV and the elucidation of the underlying causes of PML are important and active areas of research that may lead to new insights into immune function and host antiviral defense, as well as to potential new therapies.

Effect of inhibitors. The detection of specific nucleic acid (NA) sequences by PCR has revolutionized the biological and medical sciences. Real-time PCR (qPCR) opened up the possibility of obtaining quantitative results. NA extraction is a decisive step prior to qPCR since it may produce either the removal or co-extraction of inhibitory substances of the enzymatic reaction, which in turn affects the amplification efficiency. In the present work we compared the commercial NA extraction kits from Qiagen, Invitrogen and Macherey-Nagel, which were used to extract DNA from mice blood artificially infected with Trypanosoma cruzi and PP7 RNA, Pseudomonas aeruginosa bacteriophage, in spiked aqueous matrices. NA recovery efficiency in samples without inhibitors was similar for the three extraction kits. However, the Invitrogen kit was the only one that remained unaffected in the presence of inhibitors in the samples.

Hereditary leiomyomatosis and renal cell carcinoma (HLRCC) is an aggressive form of RCC characterized by germline mutation of fumarate hydratase (FH), followed by somatic loss of the remaining wild-type allele and known to be a highly metastatic and lethal malignancy compared to other RCCs. The intrinsic loss of normal tricarboxylic acid (TCA) cycle presumably aids tumorigenesis due to the necessary metabolic alterations required and the enforced dependence on glycolysis derived energy, mimicking the Warburg effect. Thus, there is considerable utility in establishing a preclinical cell model from these tumors to study energy metabolism deregulation, as well as developing new targeted therapeutic approaches for TCA cycle enzyme-deficient cancers. Here, we describe a new immortalized cell line, UOK268, derived from a patient's primary HLRCC-associated kidney cancer. This represents the first primary renal cell line to model TCA cycle gene loss and provides a perfect partner cell line to our previously described metastasis-derived HLRCC-associated cell line, UOK262. We identified a novel germline FH missense mutation, p.His192Asp, and the subsequent loss of heterozygosity in UOK268. The UOK268 cell line expressed mutant FH protein, which localized to the mitochondria, but with loss of almost all catalytic activity. The UOK268 cells had severely compromised oxidative phosphorylation and increased glycolytic flux. Ingenuity pathways analysis of human mitochondria-focused cDNA microarray (hMitChip3) gene chip data confirmed the altered mRNA expression patterns of genes involved in several important pathways, such as lipid metabolism, apoptosis, and energy production/glycolysis. UOK268 provides a unique model of a primary cell line demonstrating an enforced, irreversible Warburg effect and, combined with UOK262, provides a unique in vitro preclinical model for studying the bioenergetics of the Warburg effect in human cancer.

However, little is known about health information access and health information-seeking behaviors of this population. Objective: To examine differences in health and cancer information seeking among survey respondents who ever used the Internet and those who did not, and to explore sociodemographic and geographic trends. Methods: Data for our analyses were from a special implementation of the Health Information National Trends Survey conducted in Puerto Rico in 2009. We collected data through random digit dialing, computer-assisted telephone interviews (N = 639). The sample was drawn from the eight geographic regions of the Puerto Rico Department of Health. To account for complex survey design and perform weighted analyses to obtain population estimates, we analyzed the data using SUDAAN. Frequencies, cross-tabulation with chi-square, and logistic regression analyses were conducted. Geographic information system maps were developed to examine geographic distributions of Internet use and information seeking. Results: Of 639 participants, 142 (weighted percentage 32.7%) indicated that they had ever gone online to access the Internet or World Wide Web; this proportion was substantially lower than that of US mainland Hispanics who reported using the Internet (49%). While 101 of 142 (weighted percentage 59.6%) respondents who used the Web had ever sought health information, only 118 of 497 (weighted percentage 20.0%) of those who did not use the Web had sought health information. The pattern was similar for cancer information: 76 of 142 respondents (weighted percentage 47.2%) who used the Web had ever sought cancer information compared with 105 of 497 (weighted percentage 18.8%) of those who had not used the Web. These results were slightly lower but generally consistent with US mainland Hispanics' health (50.9%) and cancer (26.4%) information seeking. Results of separate logistic regression models controlling for sociodemographic characteristics demonstrated that, compared with individuals who did not seek health or cancer information, those who did were over 5 times as likely to have used the Internet (odds ratio 5.11, P < .001). Those who sought cancer information were over twice as likely to have used the Internet (odds ratio 2.5, P < .05). The frequency of Internet use and health and cancer information seeking was higher in the San Juan metro region than in more rural areas. Conclusions: Our results contribute to the evidence base for health and cancer communication planning for Puerto Rico, and suggest that health education and outreach efforts should explore the use of available and trusted methods of dissemination such as radio and television, as well as community-based health care providers and organizations, to supplement and encourage use of the Internet as a source of health information.

To increase patients' awareness and access to trials, we created BreastCancerTrials.org, a clinical trial matching website. BreastCancerTrials.org matched patients to trials based on their self-reported breast cancer history. It also provided a messaging platform through which patients could self-refer themselves to participating research sites. Objective: To assess adoption by research sites, acceptability to patients, and patients' accuracy in providing information to BreastCancerTrials.org. Methods: We approached 13 research sites in Northern California to list their trials on BreastCancerTrials.org. For adoption, we examined the willingness of contacted research sites to collaborate with BreastCancerTrials.org. For acceptability, we analyzed usage statistics of visitors who completed the BreastCancerTrials.org health history questionnaire in the first 14 months after launch and surveyed users who visited the website during its first year about their experience. For accuracy, we compared the self-reported health history of 20 patients against their medical records. The health history questionnaire was divided into four sections: About Me, personal information including date of birth and sex; My Health as of Today, current status including cancer stage, menopausal status, and sites with evidence of disease; My Cancer, diagnostic information such as hormone and human epidermal growth factor receptor 2 status; and My Treatment, an itemized record of past treatment including responses to therapy. Results: A total of 12 sites contributed 55 trials. Regarding acceptability, 733 visitors registered on the website; 428 reported their health history; and 407 matched to at least one trial. Of 375 patients who were sent a survey, 75 responded (20%); 23 of the 75 (31%) contacted a research site, 12 of the 23 (52%) were eligible for a trial, and 5 of the 12 (42%) reported enrolling. As for accuracy, 20 clinic visitors reported 1456 health history items, 1324 of which matched their clinic record (90.93%). Conclusions: BreastCancerTrials.org was adopted by research sites. Patients found it acceptable and were able to provide accurate information for trial matching. Based on our findings, we launched an upgraded version of BreastCancerTrials.org as a national service in October 2008.

The project was established in 1991 and will be brought to closure in 2012. Age-specific rates of total dementia and the major specific types of dementia in HAAS participants are generally similar to those reported from other geographic, cultural, and ethnic populations. Risk factors for dementia in the HAAS include midlife hypertension and other factors previously shown to influence cardiovascular disease. The autopsy component of the project has yielded novel findings, the most illuminating of which is the demonstration of 5 important lesion types linked independently to cognitive impairment. While one of these - generalized atrophy - is strongly associated with both Alzheimer lesions and microinfarcts, it also occurs in the absence of these lesions and is independently correlated with dementia. Each lesion type is viewed as representing a distinct underlying pathogenic process. Their summed influences is an especially robust correlate of dementia in the months and years prior to death.

Participants have been undergoing prospective surveillance for incident stroke and dementia and embedded within this cohort is the voluntary Framingham Brain Donation Program that was begun in 1997. Participants who register to become brain donors have had one or more brain MR and cognitive test batteries administered. In addition, they undergo neurological evaluation as indicated, record review and post-mortem next-of-kin interview to determine the presence, type and extent of antemortem, clinical neurological diagnoses and to assign a retrospective Clinical Dementia Rating (CDR) Scale score. Between 1997 and 2009 there were 1806 deaths, 186 of which were among registered brain donors and of these 139 brains could be examined. 58% were deemed cognitively normal at death. We present results for 3 projects; the first was to examine the sensitivity and specificity of our clinical diagnosis against the gold standard of pathological AD in 59 persons who underwent detailed cognitive assessment in the two years prior to death; we observed a 77.3% sensitivity (2 persons with AD were diagnosed clinically as Lewy body dementia) and a 91.9% specificity. The second examined the correlation of regional Alzheimer-type pathology to cognitive status at death among 34 persons who were over the age of 75 and without any significant vascular or alternative neurodegenerative pathology and found that neurofibrillary tangle counts distinguished between persons who were controls, had mild cognitive impairment, mild or moderate dementia; tangles in dorsolateral frontal cortex best distinguished MCI and controls. The third project examined the extent and severity of vascular pathology, again in a larger sample of varying cognitive abilities and in a subsample of persons with either amnestic or non-amnestic MCI. We observed that an aggregate ischemic injury score was significantly higher in persons with a CDR score of 0.5 than in normal controls.

In various animal models, memantine has been reported to be a neuroprotective agent that positively impacts both neurodegenerative and vascular processes. While excessive levels of glutamate result in neurotoxicity, in part through the over-activation of NMDARs, memantine-as a partial NMDAR antagonist, blocks the NMDA glutamate receptors to normalize the glutamatergic system and ameliorate cognitive and memory deficits. The key to memantine's therapeutic action lies in its uncompetitive binding to the NMDAR through which low affinity and rapid off-rate kinetics of memantine at the level of the NMDAR-channel preserves the physiological function of the receptor, underpinning memantine's tolerability and low adverse event profile. As the biochemical pathways evoked by NMDAR antagonism also play a role in PD and since no other drug is sufficiently effective to substitute for the first-line treatment of L-dopa despite its side effects, memantine may be useful in PD treatment with possibly fewer side effects. In spite of the relative modest nature of its adverse effects, memantine has been shown to provide only a moderate decrease in clinical deterioration in AD and VD, and hence efforts are being undertaken in the design of new and more potent memantine-based drugs to hopefully provide greater efficacy.

We used an established harmaline-based mouse model of ET to compare tremor suppression by 1-octanol and octanoic acid. The dose-related effect on digitized motion power within the tremor bandwidth as a fraction of overall motion power was analyzed. Both 1-octanol and octanoic acid provided significant reductions in harmaline tremor. An 8-carbon alkyl alcohol and carboxylic acid each suppress tremor in a pre-clinical mouse model of ET. Further studies are warranted to determine the safety and efficacy of such agents in humans with ET.

TI Genomic Analysis of the Emergence of Vancomycin-Resistant Staphylococcus aureus SO MBIO LA English DT Editorial Material ID HIGH-LEVEL; PENNSYLVANIA; MICHIGAN; PLASMIDS; ISOLATE AB Staphylococcus aureus is a human commensal bacterium and a prominent cause of infections globally. The high incidence of S. aureus infections is compounded by the ability of the microbe to readily acquire resistance to antibiotics. In the United States, methicillin-resistant S. aureus (MRSA) is a leading cause of morbidity and mortality by a single infectious agent. Therapeutic options for severe MRSA infections are limited to a few antibiotics to which the organism is typically susceptible, including vancomycin. Acquisition of high-level vancomycin resistance by MRSA is a major concern, but to date, there have been only 12 vancomycin-resistant S. aureus (VRSA) isolates reported in the United States and all belong to a phylogenetic lineage known as clonal complex 5. To gain enhanced understanding of the genetic characteristics conducive to the acquisition of vancomycin resistance by S. aureus, V. N. Kos et al. performed whole-genome sequencing of all 12 VRSA isolates and compared the DNA sequences to the genomes of other S. aureus strains. The findings provide new information about the evolutionary history of VRSA and identify genetic features that may bear on the relationship between S. aureus clonal complex 5 strains and the acquisition of vancomycin resistance genes from enterococci.

It has maintained this position through steady advances in technology and applications, becoming the main force behind interrogating the complexities of the immune system. Technology development was a three-pronged effort, including the hardware, reagents, and analysis algorithms to allow measurement of as many as 20 independent parameters on each cell, at tens of thousands of cells per second. In the coming years, cytometry technology will integrate with other techniques, such as transcriptomics, metabolomics, and so forth. Ongoing efforts are aimed at algorithms to analyse these aggregated datasaets over large numbers of samples. Here we review the development efforts heralding the next stage of flow cytometry.

We examined several aspects of the single wall carbon nanotubes (SWCNTs) prepared by chemical vapor deposition (CVD) processes using ethanol with the additions of ferrocene and thiophene, focusing on the potential mechanisms leading to the differences in the diameters, structures, and conductivities of the SWCNTs formed. The diameter of SWCNTs could be controlled from similar to 1.0 to similar to 5.8 nm by adjusting the concentration of thiophene used. The larger diameter SWCNTs has a higher thermal stability than smaller-diameter SWCNTs. With increasing diameter, the electrical properties of the SWCNT change from mainly semi-conducting to metallic-like. The growth mechanism of SWCNTs was subsequently studied to understand the mechanism of thiophene controlled SWCNTs formation. This study could lead to improved control over the diameter and electronic properties of SWCNTs. (C) 2012 Elsevier B.V. All rights reserved.

Intrinsic contrasts such as absorption and scattering changes have the potential to enhance diagnostics and help monitor diseased tissue. An overview of existing noncontact multispectral diffuse reflectance imaging modalities for tissue characterization based on intrinsic optical contrast due to absorption and scattering properties of tissue is given here. Also, an overview of instrumentation advances, modeling approaches, applications, and ongoing work is described, primarily in, but not limited to, skin imaging, demonstrating the benefits and limitations of wide-field diffuse reflectance imaging.

TI Spatial Correlation between Hyperpigmentary Changes on Color Fundus Photography and Hyperreflective Foci on SDOCT in Intermediate AMD SO INVESTIGATIVE OPHTHALMOLOGY & VISUAL SCIENCE LA English DT Article ID AGE-RELATED MACULOPATHY; OPTICAL COHERENCE TOMOGRAPHY; MACULAR DEGENERATION; GEOGRAPHIC ATROPHY; AUTOMATIC SEGMENTATION; SEVERITY SCALE; SD-OCT; PREVALENCE; DRUSEN; EYE AB PURPOSE. Macular hyperpigmentation is associated with progression from intermediate to advanced age-related macular degeneration (AMD). The purpose of this study was to accurately correlate hyperpigmentary changes with spectral domain optical coherence tomography (SDOCT) hyperreflective foci in eyes with non-advanced AMD. METHODS. A prospective cross-sectional analysis of 314 eyes (314 subjects) with intermediate AMD was performed in the multicenter Age-Related Eye Disease Study 2 (AREDS2) Ancillary SDOCT Study to correlate hyperpigmentary changes on color fundus photographs (CFP) with abnormal morphology on SDOCT. Spatial coregistration was performed with an automated algorithm in two nonoverlapping subsets of 20 study eyes, which permitted double-masked CFP and SDOCT grading by certified investigators. RESULTS. Macular CFP hyperpigmentation was significantly associated with SDOCT intraretinal hyperreflective foci in the 314 study eyes (P < 0.001). In a substudy of 40 eyes, automated intermodality spatial coregistration was successfully achieved in all 136 (100%) retinal regions selected for CFP and SDOCT grading. In one subset of 20 study eyes, 28 of 39 (71.8%) retinal CFP regions with hyperpigmentation were correlated with focal hyperreflectivity on SDOCT, versus seven of 39 (17.9%) control regions (P < 0.001). In another subset of 20 eyes, 21 of 29 (72.4%) SDOCT regions with hyperreflective foci were correlated with hyperpigmentary changes on CFP, versus two of 29 (6.9%) control regions (P < 0.001). CONCLUSIONS. A novel algorithm achieves automated intermodality spatial coregistration for masked grading of regions selected on CFP and SDOCT. In intermediate AMD, macular hyperpigmentation has high spatial correlation to SDOCT hyperreflective foci and often represents the same anatomical lesion. (ClinicalTrials.gov number, NCT00734487.)

We review the use of asymptotic statistical theory and sensitivity analysis to obtain measures of uncertainty for estimates of the model parameters and the basic reproductive number (R-0)-an epidemiologically significant parameter grouping. We find that estimates of different parameters, such as the transmission parameter and recovery rate, are correlated, with the magnitude and sign of this correlation depending on the value of R-0. Situations are highlighted in which this correlation allows R-0 to be estimated with greater ease than its constituent parameters. Implications of correlation for parameter identifiability are discussed. Uncertainty estimates and sensitivity analysis are used to investigate how the frequency at which data is sampled affects the estimation process and how the accuracy and uncertainty of estimates improves as data is collected over the course of an outbreak. We assess the informativeness of individual data points in a given time series to determine when more frequent sampling (if possible) would prove to be most beneficial to the estimation process. This technique can be used to design data sampling schemes in more general contexts. C1 [Capaldi, Alex] N Carolina State Univ, Ctr Quantitat Sci Biomed, Raleigh, NC 27695 USA.

TI Dietary Energy Balance Modulates Epithelial-to-Mesenchymal Transition and Tumor Progression in Murine Claudin-Low and Basal-like Mammary Tumor Models SO CANCER PREVENTION RESEARCH LA English DT Article ID BREAST-CANCER; CALORIE RESTRICTION; INITIATING CELLS; GENE-EXPRESSION; ADIPOSE-TISSUE; OBESE MICE; STEM-CELLS; GROWTH; GLAND; TUMORIGENESIS AB Using novel murine models of claudin-low and basal-like breast cancer, we tested the hypothesis that diet-induced obesity (DIO) and calorie restriction (CR) differentially modulate progression of these aggressive breast cancer subtypes. For model development, we characterized two cell lines, "mesenchymal (M)-Wnt" and "epithelial (E)-Wnt," derived from MMTV-Wnt-1 transgenic mouse mammary tumors. M-Wnt, relative to E-Wnt, cells were tumor-initiating cell (TIC)-enriched (62% vs. 2.4% CD44(high)/CD24(low)) and displayed enhanced ALDEFLUOR positivity, epithelial-to-mesenchymal transition (EMT) marker expression, mammosphere-forming ability, migration, invasion, and tumorigenicity (P < 0.001; each parameter). M-Wnt and E-Wnt cells clustered with claudin-low and basal-like breast tumors, respectively, in gene expression profiles and recapitulated these tumors when orthotopically transplanted into ovariectomized C57BL/6mice. To assess the effects of energy balance interventions on tumor progression and EMT, mice were administered DIO, control, or CR diets for 8 weeks before orthotopic transplantation of M-Wnt or E-Wnt cells (for each cell line, n = 20 mice per diet) and continued on their diets for 6 weeks while tumor growth was monitored. Relative to control, DIO enhanced M-Wnt (P = 0.01), but not E-Wnt, tumor progression; upregulated EMT-and TIC-associated markers including N-cadherin, fibronectin, TGF beta, Snail, FOXC2, and Oct4 (P < 0.05, each); and increased intratumoral adipocytes. Conversely, CR suppressed M-Wnt and E-Wnt tumor progression (P < 0.02, each) and inhibited EMT and intratumoral adipocyte accumulation. Thus, dietary energy balance interventions differentially modulate EMT and progression of claudin-low and basal-like tumors. EMT pathway components may represent targets for breaking the obesity-breast cancer link, particularly for preventing and/or controlling TIC-enriched subtypes such as claudin-low breast cancer.

The specific centromere histone H3 variant CENP-A has been described as the epigenetic mark of this chromatin region. Several laboratories have explored its properties, its partners, and its role in centromere formation. Specifically, two types of CENP-A nucleosomes have been described, suggesting there may be more complexity involved in centromere structure than previously thought. Recent work adds to this paradox by questioning the role of CENP-A as a unique centromeric mark and highlighting the assembly of a functional kinetochore in the absence of CENP-A. In this review, we discuss recent literature on the CENP-A nucleosomes and the debate on its role in kinetochore formation and centromere identity.

At the centromere, CENP-A nucleosomes form part of a chromatin landscape termed centrochromatin. This chromatin environment conveys epigenetic marks regulating kinetochore formation. Recent work sheds light on the intricate relationship between centrochromatin state, the CENP-A assembly pathway and the maintenance of centromere function. Here, we review the emerging picture of how chromatin affects mammalian kinetochore formation. We place particular emphasis on data obtained from Human Artificial Chromosome (HAC) biology and the targeted engineering of centrochromatin using synthetic HACs. We discuss implications of these findings, which indicate that a delicate balance of histone modifications and chromatin state dictates both de novo centromere formation and the maintenance of centromere identity in dividing cell populations.

Experimental Design: We studied by immunohistochemistry the phosphorylation status of proteins of the RAS/MEK/ERK and PI3K/AKT/mTOR pathways in 53 MTC tissues (18 hereditary, 35 sporadic), including 51 primary MTCs and 2 cases with only lymph node metastases (LNM). We also studied 21 autologous LNMs, matched to 21 primary MTCs. Staining was graded on a 0 to 4 scale (S score) based on the percentage of positive cells. We also studied the functional relevance of the mTOR pathway by measuring cell viability, motility, and tumorigenicity upon mTOR chemical blockade. Results: Phosphorylation of ribosomal protein S6 (pS6), a downstream target of mTOR, was evident (S >= 1) in 49 (96%) of 51 primary MTC samples. This was associated with activation of AKT (phospho-Ser473, S > 1) in 79% of cases studied. Activation of pS6 was also observed (S >= 1) in 7 (70%) of 10 hereditary C-cell hyperplasia specimens, possibly representing an early stage of C-cell transformation. It is noteworthy that 22 (96%) of 23 LNMs had a high pS6 positivity (S >= 3), which was increased compared with autologous matched primary MTCs (P = 0.024). Chemical mTOR blockade blunted viability (P < 0.01), motility (P < 0.01), and tumorigenicity (P < 0.01) of human MTC cells. Conclusion: The AKT/mTOR pathway is activated in MTC, particularly, in LNMs. This pathway sustains malignant features of MTC cell models. These findings suggest that targeting mTOR might be efficacious in patients with advanced MTC. Clin Cancer Res; 18(13); 3532-40. (C)2012 AACR.

TI Combination of an Allosteric Akt Inhibitor MK-2206 with Etoposide or Rapamycin Enhances the Antitumor Growth Effect in Neuroblastoma SO CLINICAL CANCER RESEARCH LA English DT Article ID PYRUVATE-KINASE M2; CANCER-CELLS; IN-VITRO; EXPRESSION; APOPTOSIS; PROGRESS; MECHANISMS; PERIFOSINE; MUTATIONS; PATHWAY AB Purpose: Activation of Akt is a marker of decreased event-free or overall survival in neuroblastoma patients. MK-2206, a novel allosteric Akt inhibitor, is now tested in clinical trials in adult cancers. In this study, effect of MK-2206 on tumor growth and murine survival, alone or in combination, with etoposide or rapamycin was evaluated. Experimental Design: The anticell proliferation effect of MK-2206 was tested in eight neuroblastoma cell lines by MTS assay. Caspase-3/7 activity, cell-cycle analysis, and reactive oxygen species (ROS) production were determined. Effect of MK-2206 combined with etoposide or rapamycin was evaluated in vitro and in vivo. Akt phosphorylation was measured by Western blotting in neuroblastoma cells and tumors. Results: In vitro, MK-2206 treatment inhibited neuroblastoma cell proliferation, which was accompanied by a cell line selective G(1) arrest of cell cycle or production of ROS. A synergistic effect between MK-2206 and etoposide was detected in four tested neuroblastoma cell lines via caspase-dependent apoptosis, whereas increased inhibition of cell growth induced by combination of MK-2206 and rapamycin was mediated by ROS production. In vivo, MK-2206 alone decreased tumor growth and increased murine survival at dose that inhibited Akt phosphorylation in tumors. MK-2206, in combination with etoposide or rapamycin, caused a significant decrease in tumor growth and increase of murine survival compared with MK-2206 alone. Conclusion: Akt inhibition by MK-2206 increased the efficacy of etoposide or rapamycin. Our study supports future clinical evaluation of MK-2206 in combination with conventional cytotoxic therapy or with rapamycin in high-risk neuroblastoma patients. Clin Cancer Res; 18(13); 3603-15.

We seek to investigate the expression status, clinical relevance, and functional role of miRNA in non-small cell lung cancer. Experimental Design: We conducted miRNA expression profiling in matched lung adenocarcinoma and uninvolved lung using 56 pairs of fresh-frozen (FF) and 47 pairs of formalin-fixed, paraffin-embedded (FFPE) samples from never smokers. The most differentially expressed miRNA genes were evaluated by Cox analysis and log-rank test. Among the best candidate, miR-708 was further examined for differential expression in two independent cohorts. Functional significance of miR-708 expression in lung cancer was examined by identifying its candidate mRNA target and through manipulating its expression levels in cultured cells. Results: Among the 20 miRNAs most differentially expressed between tested tumor and normal samples, high expression level of miR-708 in the tumors was most strongly associated with an increased risk of death after adjustments for all clinically significant factors including age, sex, and tumor stage (FF cohort: HR, 1.90; 95% CI, 1.08-3.35; P = 0.025 and FFPE cohort: HR, 1.93; 95% CI, 1.02-3.63; P = 0.042). The transcript for TMEM88 gene has a miR-708 binding site in its 3' UTR and was significantly reduced in tumors high of miR-708. Forced miR-708 expression reduced TMEM88 transcript levels and increased the rate of cell proliferation, invasion, and migration in culture. Conclusions: miRNA-708 acts as an oncogene contributing to tumor growth and disease progression by directly downregulating TMEM88, a negative regulator of the Wnt signaling pathway in lung cancer.

Drugs of abuse in the infected individuals further fuel the epidemic. Epidemiological studies have demonstrated that abuse of cocaine resulted in acceleration of HIV infection and the progression of NeuroAIDS. Cocaine has not only been shown to play a crucial role in promoting virus replication, but also has diverse but often deleterious effects on various cell types of the CNS. In the neuronal system, cocaine exposure results in neuronal toxicity and also potentiates gp120-induced neurotoxicity. In the astroglia and microglia, cocaine exposure leads to up-regulation of pro-inflammatory mediators such as cytokines and chemokines. These in turn, can lead to neuroinflammation and transmission of toxic responses to the neurons. Additionally, cocaine exposure can also lead to leakiness of the blood-brain barrier that manifests as enhanced transmigraiton of leukocytes/ monocytes into the CNS. Both in vitro and in vivo studies have provided valuable tools in exploring the role of cocaine in mediating HIV-associated neuropathogenesis. This review summarizes previous studies on the mechanism(s) underlying the interplay of cocaine and HIV as it relates to the CNS.

Thirty teeth were sectioned exposing the pulp chamber and divided by six groups (n = 5): NT-no treatment; CHX-2% chlorhexidine; CHXE-2% chlorhexidine + 17% EDTA; E-17% EDTA; SH5-5.25% NaOCl; SH5E-5.25% NaOCl + 17% EDTA. The inorganic and organic content was analyzed by FT-Raman. mu EDXRF examined calcium (Ca) and phosphorus (P) content as well as Ca/P ratio. Impressions of specimens were evaluated by SEM. Data were submitted to Kruskal-Wallis and Dunn tests (p < 0.05). Differences were observed among groups for the 960 cm(-1) peak. Ca and P content differences were significant (SH5 > NT = SH5E > CHX > E > CHXE). CHXE and E presented the highest Ca/P ratio values compared to the other groups (p < 0.05). The SEM images in the EDTA-treated groups had the highest number of open tubules. Erosion in the tubules was observed in CHX and SH5E groups. Endodontic agents change the inorganic and organic content of pulp chamber dentin. NaOCl used alone, or in association with EDTA, was the most effective agent considering chemical and morphological approaches. (C) 2012 Society of Photo-Optical Instrumentation Engineers (SPIE).

A more complete understanding of B. pertussis pathogenic mechanisms will involve unravelling the regulation of its impressive arsenal of virulence factors. Here we review the action of the B. pertussis response regulator BvgA in the context of what is known about bacterial RNA polymerase and various modes of transcription activation. At most virulence gene promoters, multiple dimers of phosphorylated BvgA (BvgA similar to P) bind upstream of the core promoter sequence, using a combination of high- and low-affinity sites that fill through cooperativity. Activation by BvgA similar to P is typically mediated by a novel form of class I/II mechanisms, but two virulence genes, fim2 and fim3, which encode serologically distinct fimbrial subunits, are regulated using a previously unrecognized RNA polymerase/activator architecture. In addition, the fim genes undergo phase variation because of an extended cytosine (C) tract within the promoter sequences that is subject to slipped-strand mispairing during replication. These sophisticated systems of regulation demonstrate one aspect whereby B. pertussis, which is highly clonal and lacks the extensive genetic diversity observed in many other bacterial pathogens, has been highly successful as an obligate human pathogen.

TI Human Monoclonal Antibodies Targeting Nonoverlapping Epitopes on Insulin-like Growth Factor II as a Novel Type of Candidate Cancer Therapeutics SO MOLECULAR CANCER THERAPEUTICS LA English DT Article ID CELL-LINES; IN-VIVO; IGF SYSTEM; LIBRARY; BINDING; CONSTRUCTION; CARCINOMA; COMPLEX; DOMAIN; MICE AB Soluble ligands are important targets for therapy of cancers and other diseases. Therapeutic monoclonal antibodies (mAb) against such ligands block their interactions with corresponding receptors but do not enhance their removal from the circulation and can increase their half-lives because of the long half-lives of the antibodies. We have hypothesized that mAbs targeting two or more nonoverlapping epitopes on the same ligand could form oligomeric antibody-ligand complexes that can bind to cells expressing Fc gamma receptors (Fc gamma Rs) with high avidity leading to their fast and irreversible removal from the circulation. Insulin-like growth factor II (IGF-II) is an example of such ligands and an important target for human cancer therapy. We identified two mAbs, m610.27 and m630.3, which bound to nonoverlapping epitopes on IGF-II with nanomolar affinity, and generated a bispecific antibody, m660. m660 inhibited the interaction of human IGF-II (hIGF-II) with the human breast cancer cell line MCF-7, hIGF-II-mediated IGF receptor type I and insulin receptor phosphorylation, and cell growth. In the presence of hIGF-II, large complexes of m660 were formed that bound to Fc gamma RII-expressing BJAB cells much more efficiently than the monospecific antibody-hIGF-II complexes and were presumably phagocytosed by phorbol 12-myristate 13-acetate-stimulated macrophage-like U937 cells. A mixture of m610.27 and m630.3 exhibited similar properties. To our knowledge, these mAbs are the first reported to target nonoverlapping epitopes on a cancer-related ligand and could represent a novel class of candidate therapeutics against cancers. This approach could also be used to irreversibly eliminate other disease-related soluble ligands. Mol Cancer Ther; 11(7); 1400-10. (C) 2012 AACR.

TI Replication regulation of Vibrio cholerae chromosome II involves initiator binding to the origin both as monomer and as dimer SO NUCLEIC ACIDS RESEARCH LA English DT Article ID MINI-F PLASMID; ESCHERICHIA-COLI; DNA-REPLICATION; BACTERIOPHAGE-LAMBDA; PROTEIN; GENE; SITE; INACTIVATION; DIMERIZATION; ACTIVATION AB The origin region of Vibrio cholerae chromosome II (chrII) resembles plasmid origins that have repeated initiator-binding sites (iterons). Iterons are essential for initiation as well as preventing over-initiation of plasmid replication. In chrII, iterons are also essential for initiation but over-initiation is prevented by sites called 39-mers. Both iterons and 39-mers are binding sites of the chrII specific initiator, RctB. Here, we have isolated RctB mutants that permit over-initiation in the presence of 39-mers. Characterization of two of the mutants showed that both are defective in 39-mer binding, which helps to explain their over-initiation phenotype. In vitro, RctB bound to 39-mers as monomers, and to iterons as both monomers and dimers. Monomer binding to iterons increased in both the mutants, suggesting that monomers are likely to be the initiators. We suggest that dimers might be competitive inhibitors of monomer binding to iterons and thus help control replication negatively. ChrII replication was found to be dependent on chaperones DnaJ and DnaK in vivo. The chaperones preferentially improved dimer binding in vitro, further suggesting the importance of dimer binding in the control of chrII replication.

Among the most frequently identified proteins were ATAD3 and prohibitin, which have been identified previously as nucleoid components, using a variety of methods. Both proteins are demonstrated to be required for mitochondrial protein synthesis in human cultured cells, and the major binding partner of ATAD3 is the mitochondrial ribosome. Altered ATAD3 expression also perturbs mtDNA maintenance and replication. These findings suggest an intimate association between nucleoids and the machinery of protein synthesis in mitochondria. ATAD3 and prohibitin are tightly associated with the mitochondrial membranes and so we propose that they support nucleic acid complexes at the inner membrane of the mitochondrion.

Optimal activity of pol V Mut in vitro is observed on an SSB-coated single-stranded circular DNA template in the presence of the beta/gamma complex and a transactivated RecA nucleoprotein filament, RecA*. Remarkably, under these conditions, wild-type pol V Mut efficiently incorporates ribonucleotides into DNA. A Y11A substitution in the 'steric gate' of UmuC further reduces pol V sugar selectivity and converts pol V Mut into a primer-dependent RNA polymerase that is capable of synthesizing long RNAs with a processivity comparable to that of DNA synthesis. Despite such properties, Y11A only promotes low levels of spontaneous mutagenesis in vivo. While the Y11F substitution has a minimal effect on sugar selectivity, it results in an increase in spontaneous mutagenesis. In comparison, an F10L substitution increases sugar selectivity and the overall fidelity of pol V Mut. Molecular modeling analysis reveals that the branched side-chain of L10 impinges on the benzene ring of Y11 so as to constrict its movement and as a consequence, firmly closes the steric gate, which in wild-type enzyme fails to guard against ribonucleoside triphosphates incorporation with sufficient stringency.

TI Summary of the NIAID-Sponsored Food Allergy Guidelines SO AMERICAN FAMILY PHYSICIAN LA English DT Article ID COWS MILK ALLERGY; NATURAL-HISTORY; ATOPIC-DERMATITIS; PEANUT ALLERGY; UNITED-STATES; DOUBLE-BLIND; ANAPHYLAXIS; PREVALENCE; CHILDHOOD; CHILDREN AB Patients with suspected food allergies are commonly seen in clinical practice. Although up to 15 percent of parents believe their children have food allergies, these allergies have been confirmed in only 1 to 3 percent of all Americans. Family physicians must be able to separate true food allergies from food intolerance, food dislikes, and other conditions that mimic food allergy. The most common foods that produce allergic symptoms are milk, eggs, seafood, peanuts, and tree nuts. Although skin testing and in vitro serum immunoglobulin E assays may help in the evaluation of suspected food allergies, they should not be performed unless the clinical history suggests a specific food allergen to which testing can be targeted. Furthermore, these tests do not confirm food allergy. Confirmation requires a positive food challenge or a clear history of an allergic reaction to a food and resolution of symptoms after eliminating that food from the diet. More than 70 percent of children will outgrow milk and egg allergies by early adolescence, whereas peanut allergies usually remain throughout life. The most serious allergic response to food allergy is anaphylaxis. It requires emergency care that should be initiated by the patient or family using an epinephrine autoinjector, which should be carried by anyone with a diagnosed food allergy. These and other recommendations presented in this article are derived from the Guidelines for the Diagnosis and Management of Food Allergy in the United States, published by the National Institute of Allergy and Infectious Diseases.

Recent studies have reported better outcomes and lower levels of inflammatory cytokines in obese patients with acute lung injury (ALI)/acute respiratory distress syndrome, suggesting that obesity may ameliorate the effects of this disease. We investigated the effects of obesity in leptin-resistant db/db obese and diet-induced obese mice using an inhaled LPS model of ALI. Obesity-associated effects on neutrophil chemoattractant response were examined in bone marrow neutrophils using chemotaxis and adoptive transfer; neutrophil surface levels of chemokine receptor CXCR2 were determined by flow cytometry. Airspace neutrophilia, capillary leak, and plasma IL-6 were all decreased in obese relative to lean mice in established lung injury (24 h). No difference in airspace inflammatory cytokine levels was found between obese and lean mice in both obesity models during the early phase of neutrophil recruitment (2-6 h), but early airspace neutrophilia was reduced in db/db obese mice. Neutrophils from uninjured obese mice demonstrated diminished chemotaxis to the chemokine keratinocyte cytokine compared with lean control mice, and adoptive transfer of obese mouse neutrophils into injured lean mice revealed a defect in airspace migration of these cells. Possibly contributing to this defect, neutrophil CXCR2 expression was significantly lower in obese db/db mice, and a similar but nonsignificant decrease was seen in diet-induced diet-induced obese mice. ALI is attenuated in obese mice, and this blunted response is in part attributable to an obesity-associated abnormal neutrophil chemoattractant response.

Further investigation into its clinical efficacy as well as the molecular basis of activity is likely to assist in the reversal of any resistance to its implementation. In this review we shall attempt to elucidate the current state of experimental and clinical data concerning the neuroprotective and cognitive effects of the KD in both humans and animals. Generally, it has been shown by many research groups that effective implementation of KD exerts strong neuroprotective effects with respect to social behavior and cognition. We will also elucidate the rote of KD in the interesting relationship between sleep, epilepsy and memory. Currently available evidence also indicates that, under appropriate control, and with further studies investigating any potential long-term side effects, the KD is also a relatively safe intervention, especially when compared to traditional anti-epileptic pharmacotherapeutics. In addition, due to its neuroprotective capacity, the KD may also hold potential benefit for the treatment of other neurological or neurodegenerative disorders. (C) 2011 Elsevier B.V.

TI Role of Actin-Bundling Protein Sac6 in Growth of Cryptococcus neoformans at Low Oxygen Concentration SO EUKARYOTIC CELL LA English DT Article ID SACCHAROMYCES-CEREVISIAE; MEDIATED ENDOCYTOSIS; CAPPING PROTEIN; NULL MUTATIONS; HOMOLOG SCP1; YEAST; CYTOSKELETON; GENE; MORPHOGENESIS; POLARIZATION AB Cryptococcus neoformans, the etiologic agent of cryptococcosis, is an obligately aerobic yeast that inhabits an environmental niche exposed to ambient air. The cell doubling time was significantly prolonged under 1% O-2 relative to that under normoxic conditions. No apparent cell cycle arrest occurred following a shift from ambient air to 1% O-2. However, yeast cells became hypersensitive to the actin monomer-sequestering agent latrunculin A at 1% O-2, indicating that proper actin function is critical for growth at low oxygen concentrations. We showed that Sac6, an actin-binding protein, played an important role in cell growth under low oxygen conditions. Sac6 colocalized with cortical actin patches and with the ring structures between mother cells and buds. Under low oxygen conditions, the sac6 deletion mutant grew poorly, and accumulation of the actin capping protein Cap1 was observed in the vacuole of the sac6 Delta strain. Furthermore, endocytic processes were hampered in the sac6 Delta mutant, but cell polarity and cytokinesis were not visibly disturbed. The deficiency of endocytosis in the sac6 Delta strain could be rescued by 1 M sorbitol under 1% O-2, but growth remained retarded. These results suggest an absence of a direct link in C. neoformans between endocytosis and coping with the stress of low oxygen conditions. This interpretation is further supported by the observation that deletion of three conserved genes, ABP1, CRN1, and SLA2, which play important roles in endocytosis, had no effect on growth under 1% O-2. Interestingly, deletion of SAC6 in C. neoformans had no effect on virulence in mice.

TI Oral Chronic Graft-vs.-Host Disease Characterization Using the NIH Scale SO JOURNAL OF DENTAL RESEARCH LA English DT Article DE autoimmunity; oral medicine; inflammation; stem cell(s); oral diagnosis; clinical practice guidelines ID CONSENSUS DEVELOPMENT PROJECT; WORKING GROUP-REPORT; STEM-CELL TRANSPLANTATION; CLINICAL-TRIALS; THERAPEUTIC RESPONSE; CRITERIA; CGVHD; INFLAMMATION; MULTICENTER; DIAGNOSIS AB Chronic graft-vs.-host disease (cGVHD) is a complication of allogeneic hematopoietic stem cell transplantation (alloHSCT). Oral cGVHD is manifested by mucosal, salivary, and/or sclerotic changes that have been linked to pain and poor quality of life. Our aim was to describe the demographic, clinical, and laboratory markers of oral cGVHD in alloHSCT patients (N = 187) enrolled in a cGVHD cross-sectional study at the NIH (#NCT00331968). We propose a meaningful and reproducible measure of disease defined by a cutoff point reflecting clinical minimally detectable change (0-2 = no oral cGVHD, 3-15 = oral cGVHD) on the 15-point NIH cGVHD clinician assessment scale. Forty-four patients had oral cGVHD. Oral cGVHD was associated with a quiescent or de novo type of cGVHD onset (p = 0.05), higher cGVHD severity (p = 0.033), lower albumin (p = 0.0008), higher total complement (p = 0.012), greater bother from foods or oral ulcers and greater mouth pain, and sensitivity (p < 0.0001). Multivariable logistic regression modeling with albumin, mouth pain, and total complement was 74.3% predictive of oral cGVHD and 80.2% predictive of non-oral cGVHD. We propose the use of >2 points on the NIH scale as a reproducible definition of clinically significant oral cGVHD, which may be useful in clinical settings or as eligibility criterion or as an endpoint in clinical trials.

TI Conference overview: Cancer Immunotherapy and Immunomonitoring (CITIM): Moving forward SO JOURNAL OF IMMUNOTOXICOLOGY LA English DT Article DE Cancer; immunotherapy; immunomonitoring; tumor immunology AB The immune system is a critical element involved in the control of tumor development and progression. While professionals have learned how to manipulate the immune system to generate tumor-specific immune responses, cancer immunotherapy has not yet delivered substantial clinical benefits. It has become increasingly clear that tumor-induced abnormalities in the immune system not only hamper tumor immunosurveillance, but also limit the efficacy of cancer immunotherapy. Meanwhile, the results of recent studies allow the belief that one is on the edge of a real breakthrough in this promising direction in cancer therapy. The 2(nd) International Conference 'Cancer Immunotherapy and Immunomonitoring (CITIM)' was the second meeting in Eastern Europe to specifically focus on the issue of immune regulation in the tumor environment, cancer immunotherapy, and immunomonitoring of immunotherapeutic clinical trials. This CITIM Conference held in Budapest, Hungary, was comprised from 12 plenary sessions, Best Abstract Award session, Poster session, and four Keynote lectures. Outstanding presentations and numerous productive discussions summarized the current place of the field and opened new directions for improving monitoring and therapy for patients with cancer.

This organization is thought to generate a chromatin loop between the LCR, a powerful enhancer, and active globin genes by extruding intervening regions containing inactive genes. Loop formation in the beta-globin locus requires erythroid specific transcriptional activators, co-factors and insulator-related factors. Chromatin structural features such as histone modifications and DNase I hypersensitive site formation as well as nuclear localization are all involved in loop formation in the locus through diverse mechanisms. Current models envision the formation of the loop as a necessary step in globin gene transcription activation, but this has not been definitively established and many questions remain about what is necessary to achieve globin gene transcription activation.

Pulmonary edema is also habitually present in these disorders, indicating that the microcirculatory disturbance causing edema is not confined to the brain. Both cerebral and pulmonary subclinical edema may be detected before it becomes clinically evident. Available evidence suggests that tissue hypoxia or intracellular acidosis is a commonality occurring in all of these disorders. Tissue ischemia induces physiological compensatory mechanisms to ensure cell oxygenation and carbon dioxide removal from tissues, including hyperventilation, elevation of red blood cell 2,3-bisphosphoglycerate content, and capillary vasodilatation. Clinical, laboratory, and necropsy findings in these diseases confirm the occurrence of low plasma carbon dioxide partial pressure, increased erythrocyte 2,3-bisphosphoglycerate concentration, and capillary vasodilatation with increased vascular permeability in all of them. Baseline tissue hypoxia or intracellular acidosis induced by the disease may further deteriorate when tissue oxygen requirement is no longer matched to oxygen delivery resulting in massive capillary vasodilatation with increased vascular permeability and plasma fluid leakage into the interstitial compartment leading to edema affecting the brain, lung, and other organs. Causative factors involved in the progression from physiological adaptation to devastating clinical edema are not well known and may include uncontrolled disease, malfunctioning adaptive responses, or unknown factors. The role of carbon monoxide and local nitric oxide production influencing tissue oxygenation is unclear (c) 2012 Elsevier Ltd. All rights reserved.

To achieve this goal, declarative memory ability and hippocampal volume were examined in a well-characterized sample of 138 adolescents (76 with a history of PDE and 62 from a non-exposed comparison group recruited from the same community, mean age = 14 years). Analyses were adjusted for: age at time of the assessments, gender. IQ prenatal exposure to alcohol and tobacco, and indices of early childhood environment (i.e., caregiver depression, potential for child abuse, and number of caregiver changes through 7 years of age). Results revealed that adolescents with a history of PDE performed worse on the California Verbal Learning Test Child Version (CVLT-C), and story recall from the Children's Memory Scale (CMS), and had larger hippocampal volumes, even after covariate adjustment. Hippocampal volume was negatively correlated with memory performance on the CVLT-C, with lower memory scores associated with larger volumes. These findings provide support for long-term effects of PDE on memory function and point to neural mechanisms that may underlie these outcomes. (c) 2012 Elsevier Inc. All rights reserved.

Randomized controlled trials provide the strongest evidence of intervention efficacy. The purpose of this integrative review was to evaluate trials of CRC screening interventions published between 1997 and 2007 and to identify knowledge gaps and future directions for research. Thirty-three randomized trials that met inclusion criteria were evaluated using a modified version of the TREND criteria. Significant intervention effects were reported in 6 of 10 trials focused on increasing fecal occult blood testing, 4 of 7 trials focused on sigmoidoscopy or colonoscopy completion, and 9 of 16 trials focused on completion of any screening test. Several effective interventions to promote CRC screening were identified. Future trials need to use theory to guide interventions, examine moderators and mediators, consistently report results, and use comparable outcome measures.

The etiology of COPD has been associated with apoptosis, oxidative stress, and inflammation. However, understanding of the molecular interactions that modulate COPD pathogenesis remains only partly resolved. We conducted an exploratory study on COPD etiology to identify the key molecular participants. We used information-theoretic algorithms including Context Likelihood of Relatedness (CLR), Algorithm for the Reconstruction of Accurate Cellular Networks (ARACNE), and Inferelator. We captured direct functional associations among genes, given a compendium of gene expression profiles of human lung epithelial cells. A set of genes differentially expressed in COPD, as reported in a previous study were superposed with the resulting transcriptional regulatory networks. After factoring in the properties of the networks, an established COPD susceptibility locus and domain-domain interactions involving protein products of genes in the generated networks, several molecular candidates were predicted to be involved in the etiology of COPD. These include COL4A3, CFLAR, GULP1, PDCD1, CASP10, PAX3, BOK, HSPD1, PITX2, and PML. Furthermore, T-box (TBX) genes and cyclin-dependent kinase inhibitor 2A (CDKN2A), which are in a direct transcriptional regulatory relationship, emerged as preeminent participants in the etiology of COPD by means of senescence. Contrary to observations in neoplasms, our study reveals that the expression of genes and proteins in the lung samples from patients with COPD indicate an increased tendency towards cellular senescence. The expression of the anti-senescence mediators TBX transcription factors, chromatin modifiers histone deacetylases, and sirtuins was suppressed; while the expression of TBX-regulated cellular senescence markers such as CDKN2A, CDKN1A, and CAV1 was elevated in the peripheral lung tissue samples from patients with COPD. The critical balance between senescence and anti-senescence factors is disrupted towards senescence in COPD lungs.

As these patterns unspool they decrease the overlap between odor representations and thereby increase the ability of the olfactory system to discriminate odors. Using a realistic model of the insect antennal lobe we examined two competing components of this process -lateral excitation from local excitatory interneurons, and slow inhibition from local inhibitory interneurons. We found that lateral excitation amplified differences between representations of similar odors by recruiting projection neurons that did not receive direct input from olfactory receptors. However, this increased sensitivity also amplified noisy variations in input and compromised the ability of the system to respond reliably to multiple presentations of the same odor. Slow inhibition curtailed the spread of projection neuron activity and increased response reliability. These competing influences must be finely balanced in order to decorrelate odor representations.

Some act as classical driver inputs while others are thought to modulate PN responses based on sensory or behavioral context, but the biophysical mechanisms that mediate classical-contextual interactions in these dendrites remain poorly understood. We hypothesized that if two excitatory pathways bias their synaptic projections towards proximal vs. distal ends of the basal branches, the very different local spike thresholds and attenuation factors for inputs near and far from the soma might provide the basis for a classical-contextual functional asymmetry. Supporting this possibility, we found both in compartmental models and electrophysiological recordings in brain slices that the responses of basal dendrites to spatially separated inputs are indeed strongly asymmetric. Distal excitation lowers the local spike threshold for more proximal inputs, while having little effect on peak responses at the soma. In contrast, proximal excitation lowers the threshold, but also substantially increases the gain of distally-driven responses. Our findings support the view that PN basal dendrites possess significant analog computing capabilities, and suggest that the diverse forms of nonlinear response modulation seen in the neocortex, including uni-modal, cross-modal, and attentional effects, could depend in part on pathway-specific biases in the spatial distribution of excitatory synaptic contacts onto PN basal dendritic arbors.

Understanding the process of how histone chaperones associate and dissociate from the histones can help clarify their roles in chromosome metabolism. Some histone chaperones are intrinsically disordered proteins (IDPs). Recent studies of IDPs revealed that the recognition of the biomolecules is realized by the flexibility and dynamics, challenging the century-old structure-function paradigm. Here we investigate the binding between intrinsically disordered chaperone Chz1 and histone variant H2A.Z-H2B by developing a structure-based coarse-grained model, in which Debye-Huckel model is implemented for describing electrostatic interactions due to highly charged characteristic of Chz1 and H2A.Z-H2B. We find that major structural changes of Chz1 only occur after the rate-limiting electrostatic dominant transition state and Chz1 undergoes folding coupled binding through two parallel pathways. Interestingly, although the electrostatic interactions stabilize bound complex and facilitate the recognition at first stage, the rate for formation of the complex is not always accelerated due to slow escape of conformations with non-native electrostatic interactions at low salt concentrations. Our studies provide an ionic-strength-controlled binding/folding mechanism, leading to a cooperative mechanism of "local collapse or trapping" and "fly-casting" together and a new understanding of the roles of electrostatic interactions in IDPs' binding.

However, evidence suggests that, unlike cells found in lymphoid organs that productively respond to acute infections, immune cells in tumors are dysregulated and functionally impaired. Tumor masses can contain regulatory lymphocytes, myeloid-derived suppressor cells, alternatively activated macrophages, and dendritic cells. Ablation or reprogramming of this aberrant microenvironment might dramatically augment cancer therapies, and this strategy is currently being deployed in a variety of clinical trials. A better understanding of the cellular constituents of tumors and the mechanisms involved in immune evasion may help guide the next generation of innovative cancer immunotherapies.

Prognosis for this cancer is generally poor because of late-stage diagnosis and resistance to current conventional therapies. The damage-associated molecular pattern protein HMGB1 has been implicated previously in transformation of mesothelial cells. Here we show that HMGB1 establishes an autocrine circuit in malignant mesothelioma cells that influences their proliferation and survival. Malignant mesothelioma cells strongly expressed HMGB1 and secreted it at high levels in vitro. Accordingly, HMGB1 levels in malignant mesothelioma patient sera were higher than that found in healthy individuals. The motility, survival, and anchorage-independent growth of HMGB1-secreting malignant mesothelioma cells was inhibited in vitro by treatment with monoclonal antibodies directed against HMGB1 or against the receptor for advanced glycation end products, a putative HMGB1 receptor. HMGB1 inhibition in vivo reduced the growth of malignant mesothelioma xenografts in severe-combined immunodeficient mice and extended host survival. Taken together, our findings indicate that malignant mesothelioma cells rely on HMGB1, and they offer a preclinical proof-of-principle that antibody-mediated ablation of HMBG1 is sufficient to elicit therapeutic activity, suggesting a novel therapeutic approach for malignant mesothelioma treatment.

TI Antibody Targeting of Cell-Bound MUC1 SEA Domain Kills Tumor Cells SO CANCER RESEARCH LA English DT Article ID BREAST-CANCER PATIENTS; PHASE-I; COLORECTAL-CANCER; PROSTATE-CANCER; OVARIAN-CANCER; PREFERENTIAL EXPRESSION; GENE-EXPRESSION; ANTIGEN MUC1; PROTEIN; ONCOPROTEIN AB The cell-surface glycoprotein MUC1 is a particularly appealing target for antibody targeting, being selectively overexpressed in many types of cancers and a high proportion of cancer stem-like cells. However the occurrence of MUC1 cleavage, which leads to the release of the extracellular alpha subunit into the circulation where it can sequester many anti-MUC1 antibodies, renders the target problematic to some degree. To address this issue, we generated a set of unique MUC1 monoclonal antibodies that target a region termed the SEA domain that remains tethered to the cell surface after MUC1 cleavage. In breast cancer cell populations, these antibodies bound the cancer cells with high picomolar affinity. Starting with a partially humanized antibody, DMB5F3, we created a recombinant chimeric antibody that bound a panel of MUC1(+) cancer cells with higher affinities relative to cetuximab (anti-EGFR1) or tratuzumab (anti-erbB2) control antibodies. DMB5F3 internalization from the cell surface occurred in an efficient temperature-dependent manner. Linkage to toxin rendered these DMB5F3 antibodies to be cytotoxic against MUC1(+) cancer cells at low picomolar concentrations. Our findings show that high-affinity antibodies to cell-bound MUC1 SEA domain exert specific cytotoxicity against cancer cells, and they point to the SEA domain as a potential immunogen to generate MUC1 vaccines.

TI Fertility Drugs and Young-Onset Breast Cancer: Results From the Two Sister Study SO JOURNAL OF THE NATIONAL CANCER INSTITUTE LA English DT Article ID IN-VITRO FERTILIZATION; RANDOMIZED CONTROLLED-TRIAL; OVULATION INDUCTION; CLOMIPHENE CITRATE; INFERTILE WOMEN; POSSIBLE ASSOCIATION; GAVE BIRTH; RISK; COHORT; PREGNANCY AB Background Fertility drugs stimulate hyperovulation, which may have implications for breast cancer. We examined the association between use of fertility drugs (clomiphene citrate [CC] and follicle-stimulating hormone [FSH]) and subsequent risk of young-onset (<50 years at diagnosis) breast cancer. Methods We conducted the Two Sister Study, a sister-matched case-control study, by enrolling 1422 women between September 2008 and December 2010, who were younger than age 50 years at diagnosis with breast cancer and were enrolled within 4 years of diagnosis, and 1669 breast cancer-free control sisters from the Sister Study. Participants reported their use of fertility drugs (CC and FSH) and ever-users reported whether a pregnancy had resulted that lasted 10 or more (10+) weeks. Conditional logistic regression was used to estimate confoundera-djusted odds ratios (ORs) and 95% confidence intervals (CIs) for fertility drug use with or without conception of a 10+ week pregnancy. Results A total of 288 participants reported having used ovulation-stimulating drugs (193 CC only, 29 FSH only, and 66 both). Overall, women who had used fertility drugs showed a non-statistically significantly decreased risk of breast cancer, compared with nonusers (OR = 0.82, 95% CI = 0.63 to 1.08). Women who had used fertility drugs but had not conceived a 10+ week pregnancy under treatment showed a statistically significantly decreased risk of breast cancer compared with nonusers (OR = 0.62, 95% CI = 0.43 to 0.89). Women who had used fertility drugs and conceived a 10+ week pregnancy under treatment showed a statistically significantly increased risk of breast cancer compared with unsuccessfully treated women (OR = 1.82, 95% CI = 1.10 to 3.00), although their risk was not increased compared with women who had not used fertility drugs (OR = 1.13, 95% CI = 0.78 to 1.64). Conclusions In the absence of a 10+ week pregnancy under treatment, exposure to ovulation-stimulating fertility drugs was associated with reduced risk of young-onset breast cancer. This apparent association was absent in women who conceived a 10+ week pregnancy under treatment, for whom risk was higher than that of unsuccessfully treated women, but similar to that of untreated women.

A portion of this variability could potentially be explained by genetic factors. Recent literature shows that the neurotransmitter serotonin plays an important role in memory processes, as enhancements of brain serotonin have led to memory improvement. Here, we have begun to explore genetic contributions to the performance and underlying brain activity associated with source memory monitoring. Using a source recognition memory task during fMRI scanning, this study offers evidence that older adults who carry a short allele (S-car) of the serotonin transporter linked polymorphic region (5-HTTLPR) in the SLC6A4 gene show specific deficits in source memory monitoring relative to older adults who are homozygous for the long allele (LL). These deficits are accompanied by less neural activity in regions of prefrontal cortex that have been shown to support accurate memory monitoring. Moreover, while the older adult LL group's behavioral performance does not differ from younger adults, their brain activation reveals evidence of compensatory activation that likely supports their higher performance level. These results provide preliminary evidence that the long-allele homozygous profile is cognitively beneficial to older adults, particularly for memory functioning. Published by Elsevier Ltd.

TI Association between subcortical volumes and verbal memory in unmedicated depressed patients and healthy controls SO NEUROPSYCHOLOGIA LA English DT Article DE Depression; Verbal memory; California Verbal Learning Test; Subcortical volumes; Hippocampus; Serial clustering ID RECURRENT MAJOR DEPRESSION; BASAL GANGLIA; HIPPOCAMPAL VOLUME; EPISODIC MEMORY; MOOD DISORDERS; NEUROPSYCHIATRIC DISORDERS; UNIPOLAR DEPRESSION; LEARNING-STRATEGIES; SELF-REPORT; PERFORMANCE AB Research has shown poor performance on verbal memory tasks in patients with major depressive disorder relative to healthy controls, as well as structural abnormalities in the subcortical structures that form the limbic-cortical-striatal-pallidal-thalamic circuitry. Few studies, however, have attempted to link the impairments in learning and memory in depression with these structural abnormalities, and of those which have done so, most have included patients medicated with psychotropic agents likely to influence cognitive performance. This study thus examines the relationship between subcortical structural abnormalities and verbal memory using the California Verbal Learning Test (CVLT) in unmedicated depressed patients. A T1 weighted magnetic resonance imaging scan and the CVLT were obtained on 45 subjects with major depressive disorder and 44 healthy controls. Using the FMRIB's Integrated Registration and Segmentation Tool (FIRST) volumes of selected subcortical structures were segmented and correlated with CVLT performance. Depressed participants showed significantly smaller right thalamus and right hippocampus volumes than healthy controls. Depressed participants also showed impaired performance on global verbal learning ability, and appeared to depend upon an inferior memory strategy (serial clustering). Measures of serial clustering were correlated significantly with right hippocampal volumes in depressed participants. Our findings indicate that depressed participants and healthy controls differ in the memory strategies they employ, and that while depressed participants had a smaller hippocampal volume, there was a positive correlation between volume and use of an inferior memory strategy. This suggests that larger hippocampal volume is related to better memory recall in depression, but specifically with regard to utilizing an inferior memory strategy. (C) 2012 Elsevier Ltd.

Within this context, the management of lymph node-negative breast cancer is the subject of much debate with particular emphasis on the requirement for adjuvant chemotherapy. The identification of prognostic and predictive biomarkers in this group of patients is crucial. Here, we demonstrate by tissue microarray and automated image analysis that the cocaine- and amphetamine-regulated transcript (CART) is expressed in primary and metastatic breast cancer and is an independent poor prognostic factor in estrogen receptor (ER)-positive, lymph node-negative tumors in two separate breast cancer cohorts (n = 690; P = 0.002, 0.013). We also show that CART increases the transcriptional activity of ER alpha in a ligand-independent manner via the mitogen-activated protein kinase pathway and that CART stimulates an autocrine/paracrine loop within tumor cells to amplify the CART signal. Additionally, we demonstrate that CART expression in ER-positive breast cancer cell lines protects against tamoxifen-mediated cell death and that high CART expression predicts disease outcome in tamoxifen-treated patients in vivo in three independent breast cancer cohorts. We believe that CART profiling will help facilitate stratification of lymph node-negative breast cancer patients into high- and low-risk categories and allow for the personalization of therapy.

Herein, we describe the first kinetic T cell response to a low-dose DENV-1 vaccination study (10 PFU) in humans. Using flow cytometry, we found that proinflammatory cytokines, IFN gamma, TNF alpha, and IL-2, were generated by DENV-1-specific CD4(+) cells 21 days post-DENV-1 exposure, and their production continued through the latest time-point, day 42 (p<0.0001 for all cytokines). No statistically significant changes were observed at any time-points for IL-10 (p = 0.19), a regulatory cytokine, indicating that the response to DENV-1 was primarily proinflammatory in nature. We also observed little T cell cross-reactivity to the other 3 DENV serotypes. The percentage of multifunctional T cells (T cells making >= 2 cytokines simultaneously) increased with time post-DENV-1 exposure (p<0.0001). The presence of multifunctional T cells together with neutralizing antibody data suggest that the immune response generated to the vaccine may be protective. This work provides an initial framework for defining primary T cell responses to each DENV serotype and will enhance the evaluation of a tetravalent DENV vaccine.

Volf, Petr TI Kinetics of Antibody Response in BALB/c and C57BL/6 Mice Bitten by Phlebotomus papatasi SO PLOS NEGLECTED TROPICAL DISEASES LA English DT Article ID LUTZOMYIA-LONGIPALPIS SALIVA; VISCERAL LEISHMANIASIS; CUTANEOUS LEISHMANIASIS; IMMUNE-RESPONSE; TRIATOMA-INFESTANS; MOSQUITO BITES; GLAND ANTIGENS; ENDEMIC AREAS; SAND FLIES; EXPOSURE AB Background: Phlebotomine sand flies are blood-sucking insects transmitting Leishmania parasites. In bitten hosts, sand fly saliva elicits specific immune response and the humoral immunity was shown to reflect the intensity of sand fly exposure. Thus, anti-saliva antibodies were suggested as the potential risk marker of Leishmania transmission. In this study, we examined the long-term kinetics and persistence of anti-Phlebotomus papatasi saliva antibody response in BALB/c and C57BL/6 mice. We also tested the reactivity of mice sera with P. papatasi salivary antigens and with the recombinant proteins. Methodology/Principal Findings: Sera of BALB/c and C57BL/6 mice experimentally bitten by Phlebotomus papatasi were tested by ELISA for the presence of anti-saliva IgE, IgG and its subclasses. We detected a significant increase of specific IgG and IgG1 in both mice strains and IgG2b in BALB/c mice that positively correlated with the number of blood-fed P. papatasi females. Using western blot and mass spectrometry we identified the major P. papatasi antigens as Yellow-related proteins, D7-related proteins, antigen 5-related proteins and SP-15-like proteins. We therefore tested the reactivity of mice sera with four P. papatasi recombinant proteins coding for most of these potential antigens (PpSP44, PpSP42, PpSP30, and PpSP28). Each mouse serum reacted with at least one of the recombinant protein tested, although none of the recombinant proteins were recognized by all sera. Conclusions: Our data confirmed the concept of using anti-sand fly saliva antibodies as a marker of sand fly exposure in Phlebotomus papatasi-mice model. As screening of specific antibodies is limited by the availability of salivary gland homogenate, utilization of recombinant proteins in such studies would be beneficial. Our present work demonstrates the feasibility of this implementation. A combination of recombinant salivary proteins is recommended for evaluation of intensity of sand fly exposure in endemic areas and for estimation of risk of Leishmania transmission.

TI Fine Scale Spatiotemporal Clustering of Dengue Virus Transmission in Children and Aedes aegypti in Rural Thai Villages SO PLOS NEGLECTED TROPICAL DISEASES LA English DT Article ID POLYMERASE-CHAIN-REACTION; PRIMARY-SCHOOL CHILDREN; KAMPHAENG PHET; PUERTO-RICO; VECTOR; CULICIDAE; DIPTERA; BLOOD; PATTERNS; KINETICS AB Background: Based on spatiotemporal clustering of human dengue virus (DENV) infections, transmission is thought to occur at fine spatiotemporal scales by horizontal transfer of virus between humans and mosquito vectors. To define the dimensions of local transmission and quantify the factors that support it, we examined relationships between infected humans and Aedes aegypti in Thai villages. Methodology/Principal Findings: Geographic cluster investigations of 100-meter radius were conducted around DENV-positive and DENV-negative febrile "index" cases (positive and negative clusters, respectively) from a longitudinal cohort study in rural Thailand. Child contacts and Ae. aegypti from cluster houses were assessed for DENV infection. Spatiotemporal, demographic, and entomological parameters were evaluated. In positive clusters, the DENV infection rate among child contacts was 35.3% in index houses, 29.9% in houses within 20 meters, and decreased with distance from the index house to 6.2% in houses 80-100 meters away (p<0.001). Significantly more Ae. aegypti were DENV-infectious (i.e., DENV-positive in head/thorax) in positive clusters (23/1755; 1.3%) than negative clusters (1/1548; 0.1%). In positive clusters, 8.2% of mosquitoes were DENV-infectious in index houses, 4.2% in other houses with DENV-infected children, and 0.4% in houses without infected children (p<0.001). The DENV infection rate in contacts was 47.4% in houses with infectious mosquitoes, 28.7% in other houses in the same cluster, and 10.8% in positive clusters without infectious mosquitoes (p<0.001). Ae. aegypti pupae and adult females were more numerous only in houses containing infectious mosquitoes. Conclusions/Significance: Human and mosquito infections are positively associated at the level of individual houses and neighboring residences. Certain houses with high transmission risk contribute disproportionately to DENV spread to neighboring houses. Small groups of houses with elevated transmission risk are consistent with over-dispersion of transmission (i.e., at a given point in time, people/mosquitoes from a small portion of houses are responsible for the majority of transmission).

There is a lack of mechanistic data concerning the effects of CeO2 NPs on primary human cells. We aimed at characterizing the cytotoxic effects of CeO2 NPs in human peripheral blood monocytes. CeO2 NPs and their suspensions were thoroughly characterized, including using transmission electron microscopy (TEM), dynamic light scattering, and zeta potential analysis. Blood from healthy human volunteers was drawn through phlebotomy, and CD14+ cells were isolated. Cells were exposed to CeO2 NPs (0.5-10 mu g/mL) for 20 or 40 h, and mechanisms of cell injury were studied. TEM revealed that CeO2 NPs are Internalized by monocytes and are found either in vesicles or free in the cytoplasm. CeO2 NP exposure leads to decrease in cell viability, and treated cells exhibit characteristic hallmarks of apoptosis (activation of Bax, loss of mitochondrial membrane potential, DNA fragmentation). CeO2 NP toxicity is caused by mitochondrial damage and overexpression of apoptosis inducing factor, but is not due to caspase activation or reactive oxygen species production. Moreover, CeO2 NP exposure leads to autophagy, which is further increased after pharmacological inhibition of tumor suppressor protein p53. Inhibition of autophagy partially reverses cell death by CeO2 NPs. It is concluded that CeO2 NPs are toxic to primary human monocytes at relatively low doses.

TI Examination of ancestral informative markers and self-reported race with tumor characteristics of breast cancer among black and white women SO BREAST CANCER RESEARCH AND TREATMENT LA English DT Article DE Breast cancer; Tumor characteristics; Ancestry informative markers; Self-reported race ID AFRICAN-AMERICAN WOMEN; MULTILOCUS GENOTYPE DATA; REPRODUCTIVE EXPERIENCES; ADMIXTURE SCAN; POPULATIONS; INFERENCE; HEALTH; GENES; RISK AB African American (AA) women have a higher mortality from breast cancer (BC) compared to European American (EA) women. This may be due to the higher proportion of AA women with tumors that are diagnosed at more advanced stages and are characterized as being estrogen receptor negative (ER-)/progesterone receptor negative (PR-). Our study sought to determine whether self-reported race and percent African ancestry were associated with BC tumor characteristics. In a multi-center, population-based case-control study of BC, we determined percent African ancestry using ancestry informative markers (AIM) among women self-reporting race as AA or Black. BC tumor characteristics were associated with self-reported race (including a 30 % reduction in ER+/PR+ tumors [95 % confidence interval [CI]: 0.6-0.9] and a 1.5-fold increased risk of high grade [95 % CI: 1.2-1.9] for AA women compared to EA women). AIMs among AA women were not associated with BC tumor characteristics (AA women with a parts per thousand yen95 % versus < 80 % African ancestry, odds ratio [OR] = 1.0 for ER+/PR+ [95 % CI: 0.6-1.8] and OR = 0.9 for high-grade tumors [95 % CI: 0.6-1.4]). Similar findings were observed for BC stage. While BC subtypes were associated with self-reported race, BC subtypes were not associated with percent African ancestry. These study results suggest that subtle differences in percent African ancestry are less important than the overall presence of African ancestry in relation to BC tumor characteristics.

TI Long-term survival of older breast cancer patients: population-based estimates over three decades SO BREAST CANCER RESEARCH AND TREATMENT LA English DT Article DE Breast cancer; Survival; Aging; SEER ID UNITED-STATES; ADJUVANT CHEMOTHERAPY; WOMEN; AGE; THERAPY; MAMMOGRAPHY; TAMOXIFEN; DIAGNOSIS; TRIALS; STAGE AB Significant progress has been made in the treatment of breast cancer. However, treatment effect on survival in older patients, particularly the "oldest old" (85+ years), with breast cancer is not clear. Data from the Surveillance, Epidemiology, and End Results databases were used to determine relative survival of older patients with breast cancer for up to 9 years following diagnosis. We compared trends in survival and stage distribution in the years 1977-1986, 1987-1996, and 1997-2006 in patients from 65 to 74, 75 to 84, and 85+ years of age. Between 1977-1986 and 1997-2006, 1 year survival increased from 94.9 to 97.9 %, 93.6 to 96.7 %, and 88.5 to 93.5 % in the 65-74, 75-84, and 85+ age groups, respectively. Survival gains increased with each year in all three age groups with the largest improvement seen at 9 years of follow-up. Although the "oldest old" had the lowest survival rates, improvement in survival was greatest in this age group with greater than 20 % increase in survival at 9 years. There was an increased diagnosis of localized breast cancer and decrease in regional disease in all age groups over the three decades. In conclusion, relative survival for older patients has increased considerably in the interval between 1977 and 2006, with the largest improvement seen in those 85 years and older. These results likely indicate that the benefit from advances in therapy and supportive care also extends to older patients with breast cancer, including the 'oldest old', but the impact of early diagnosis on survival requires further clarification.

In 1998, the U.S. Food and Drug Administration (FDA) used these studies as a basis for approving tamoxifen for primary breast chemoprevention in both premenopausal and postmenopausal women at high risk. In 2007, the FDA approved raloxifene for primary breast cancer chemoprevention for postmenopausal women. Data from the year 2010 National Health Interview Survey were analyzed to estimate the prevalence of tamoxifen and raloxifene use for chemoprevention of primary breast cancers among U.S. women. Prevalence of use of chemopreventive agents for primary tumors was 20,598 (95 % CI, 518-114,864) for U.S. women aged 35-79 for tamoxifen. Prevalence was 96,890 (95 % CI, 41,277-192,391) for U.S. women aged 50-79 for raloxifene. Use of tamoxifen and raloxifene for prevention of primary breast cancers continues to be low. In 2010, women reporting medication use for breast cancer chemoprevention were primarily using the more recently FDA approved drug raloxifene. Multiple possible explanations for the low use exist, including lack of awareness and/or concern about side effects among primary care physicians and patients.

An interaction was observed between 2-amino-3,8-dimethylimidazo[4,5-f]quinoxaline (MeIQx) intake and the NAT1 polymorphism rs6586714 in the adenoma study (P-interaction = 0.001). Among individuals carrying a GG genotype, high MeIQx intake was associated with a 43% increased risk of adenoma (95% CI 1.111.85, P-trend = 0.07), whereas the reverse was observed among carriers of the A variant (OR = 0.50, 95% CI 0.300.84, P-trend = 0.01). In addition, we observed some suggestive (P < 0.05) modifying effects for SNPs in other XME genes (UGT1A, CYP2E1, EPHX1, AHR and GSTM3), but these were not significant after adjustment for multiple testing. This large and comprehensive study of XME genes, meat mutagens and the risk of colorectal tumours found that a NAT1 polymorphism modified the association between MeIQx intake and colorectal adenoma risk.

TI Pathway analysis of genome-wide association study data highlights pancreatic development genes as susceptibility factors for pancreatic cancer SO CARCINOGENESIS LA English DT Article ID NUCLEAR FACTOR 1-ALPHA; C-REACTIVE PROTEIN; SIGNALING PATHWAYS; LOGIC REGRESSION; MICE LEADS; RISK; METABOLISM; MUTATIONS; GLUCOSE; LIVER AB Four loci have been associated with pancreatic cancer through genome-wide association studies (GWAS). Pathway-based analysis of GWAS data is a complementary approach to identify groups of genes or biological pathways enriched with disease-associated single-nucleotide polymorphisms (SNPs) whose individual effect sizes may be too small to be detected by standard single-locus methods. We used the adaptive rank truncated product method in a pathway-based analysis of GWAS data from 3851 pancreatic cancer cases and 3934 control participants pooled from 12 cohort studies and 8 case-control studies (PanScan). We compiled 23 biological pathways hypothesized to be relevant to pancreatic cancer and observed a nominal association between pancreatic cancer and five pathways (P < 0.05), i.e. pancreatic development, Helicobacter pylori lacto/neolacto, hedgehog, Th1/Th2 immune response and apoptosis (P = 2.0 x 10(-6), 1.6 x 10(-5), 0.0019, 0.019 and 0.023, respectively). After excluding previously identified genes from the original GWAS in three pathways (NR5A2, ABO and SHH), the pancreatic development pathway remained significant (P = 8.3 x 10(-5)), whereas the others did not. The most significant genes (P < 0.01) in the five pathways were NR5A2, HNF1A, HNF4G and PDX1 for pancreatic development; ABO for H.pylori lacto/neolacto; SHH for hedgehog; TGFBR2 and CCL18 for Th1/Th2 immune response and MAPK8 and BCL2L11 for apoptosis. Our results provide a link between inherited variation in genes important for pancreatic development and cancer and show that pathway-based approaches to analysis of GWAS data can yield important insights into the collective role of genetic risk variants in cancer.

TI Stromal adipocyte PPAR protects against breast tumorigenesis SO CARCINOGENESIS LA English DT Article ID ACTIVATED RECEPTOR-GAMMA; DMBA-INDUCED MAMMARY; DIFFERENTIAL EXPRESSION; IN-VITRO; INSULIN-RESISTANCE; TUMOR-SUPPRESSOR; CANCER CELLS; LEPTIN; MICE; GENE AB Peroxisome proliferator-activated receptor (PPAR) regulates the expression of genes essential for fat storage, primarily through its activity in adipocytes. It also has a role in carcinogenesis. PPAR normally stops the in vivo progression of 7,12-dimethylbenz[a]anthracene (DMBA)-mediated breast tumours as revealed with PPAR haploinsufficient mice. Since many cell types associated with the mammary gland express PPAR, each with unique signal patterns, this study aimed to define which tissues are required for PPAR-dependent antitumour effects. Accordingly, adipocyte-specific PPAR knockout (PPAR-A KO) mice and their wild-type (PPAR-WT) controls were generated, and treated with DMBA for 6 weeks to initiate breast tumorigenesis. On week 7, mice were randomized to continue on normal chow diet or one supplemented with rosiglitazone (ROSI), and followed for 25 weeks for tumour outcomes. In PPAR-A KO versus PPAR-WT mice, malignant mammary tumour incidence was significantly higher and mammary tumour latency was decreased. DMBA + ROSI treatment reduced average mammary tumour volumes by 50%. Gene expression analyses of mammary glands by quantitative real-time polymerase chain reaction and immunofluorescence indicated that untreated PPAR-A KOs had significantly decreased BRCA1 expression in mammary stromal adipocytes. Compared with PPAR-WT mice, serum leptin levels in PPAR-A KOs were also significantly higher throughout the study. Together, these data are the first to suggest that in vivo PPAR expression in mammary stromal adipocytes attenuates breast tumorigenesis through BRCA1 upregulation and decreased leptin secretion. This study supports a protective effect of activating PPAR as a novel chemopreventive therapy for breast cancer.

Our objective is to describe the prevalence of CVD risk factors applying standard criteria and use of CVD risk factorlowering medications in contemporary KTRs. Methods The Folic Acid for Vascular Outcome Reduction in Transplantation study enrolled and collected medication data on 4107 KTRs with elevated homocysteine and stable graft function an average of five yr post-transplant. Results CVD risk factors were common (hypertension or use of blood pressure (BP) lowering medication in 92%, borderline or elevated low-density lipoprotein (LDL) or use of lipid-lowering agent in 66%, history of diabetes mellitus in 41%, and obesity in 38%); prevalent CVD was reported in 20% of study participants. National Kidney Foundation BP guidelines (BP <130/80 mmHg) were not met by 69% of participants. Uncontrolled hypertension (BP of 140/90 mmHg or higher) was present in 44% of those taking antihypertension medication; 18% of participants had borderline or elevated LDL, of which 60% were untreated, and 31% of the participants with prevalent CVD were not using an antiplatelet agent. Conclusion There is opportunity to improve treatment and control of traditional CVD risk factors in kidney transplant recipients.

Questioning the notion of a common factor as an as-yet-unobserved common cause of a behaviour domain's exemplars, the authors propose using graphical representations to inspire hypotheses of more complex causal structures. I do not find the case for the de-emphasis of the common factor model to be compelling for those behaviour domains (cognitive abilities) with which I am most familiar.

The growing armamentarium of scientifically proven interventions-including the use of antiretroviral medications to treat and prevent HIV infection, voluntary medical male circumcision, education and counseling about HIV risk and behavior change, condom use, drug and alcohol treatment, and needle exchange programs for injection drug users-offers an unprecedented opportunity to make major gains in the fight against HIV/AIDS. Combining and implementing these interventions as effectively as possible has the potential to dramatically change the trajectory of the HIV/AIDS pandemic. Substantive challenges remain, especially obtaining sufficient funding for HIV-related interventions and developing the operational capacity to deliver them cost-effectively to all in need. If these challenges can be met, the world will have a clear path toward an "AIDS-free generation" in which new HIV infections, as well as illness and death due to AIDS, are increasingly rare.

We developed a rapid single-well PCR assay to identify RRDR mutations. The assay uses sloppy molecular beacons to probe an asymmetric PCR of the M. tuberculosis RRDR by melting temperature (T-m) analysis. A three-point T-m code is generated which distinguishes wild-type from mutant RRDR DNA sequences in approximately 2 h. The assay was validated on synthetic oligonucleotide targets containing the 44 most common RRDR mutations. It was then tested on a panel of DNA extracted from 589 geographically diverse clinical M. tuberculosis cultures, including isolates with wild-type RRDR sequences and 25 different RRDR mutations. The assay detected 236/236 RRDR mutant sequences as mutant (sensitivity, 100%; 95% confidence interval [CI], 98 to 100%) and 353/353 RRDR wild-type sequences as wild type (specificity, 100%; 95% CI, 98.7 to 100%). The assay identified 222/225 rifampin-resistant isolates as rifampin resistant (sensitivity, 98.7%; 95% CI, 95.8 to 99.6%) and 335/336 rifampin-susceptible isolates as rifampin susceptible (specificity, 99.7%; 95% CI, 95.8 to 99.6%). All mutations were either individually identified or clustered into small mutation groups using the triple T-m code. The assay accurately identified mixed (heteroresistant) samples and was shown analytically to detect RRDR mutations when present in at least 40% of the total M. tuberculosis DNA. This was at least as accurate as Sanger DNA sequencing. The assay was easy to use and well suited for high-throughput applications. This new sloppy molecular beacon assay should greatly simplify rifampin resistance testing in clinical laboratories.

Here we show in mice that the transcription factor PAX6, well-known for its retina-promoting activity, also plays a crucial role in early pigment epithelium development. This role is seen, however, only in a background genetically sensitized by mutations in the pigment cell transcription factor MITF. In fact, a reduction in Pax6 gene dose exacerbates the RPE-to-retina transdifferentiation seen in embryos homozygous for an Mitf null allele, and it induces such a transdifferentiation in embryos that are either heterozygous for the Mitf null allele or homozygous for an RPE-specific hypomorphic Mitf allele generated by targeted mutation. Conversely, an increase in Pax6 gene dose interferes with transdifferentiation even in homozygous Mitf null embryos. Gene expression analyses show that, together with MITF or its paralog TFEC, PAX6 suppresses the expression of Fgf15 and Dkk3. Explant culture experiments indicate that a combination of FGF and DKK3 promote retina formation by inhibiting canonical WNT signaling and stimulating the expression of retinogenic genes, including Six6 and Vsx2. Our results demonstrate that in conjunction with Mitf/Tfec Pax6 acts as an anti-retinogenic factor, whereas in conjunction with retinogenic genes it acts as a pro-retinogenic factor. The results suggest that careful manipulation of the Pax6 regulatory circuit may facilitate the generation of retinal and pigment epithelium cells from embryonic or induced pluripotent stem cells.

TI The Three Faces of Riboviral Spontaneous Mutation: Spectrum, Mode of Genome Replication, and Mutation Rate SO PLOS GENETICS LA English DT Article ID BACTERIOPHAGE-Q-BETA; COLIPHAGE-Q-BETA; SECONDARY STRUCTURE MODEL; CIS-ACTING ELEMENTS; PLANT RNA VIRUS; PHAGE-Q-BETA; ESCHERICHIA-COLI; RIBONUCLEIC ACID; INFECTION CYCLE; QBETA-REPLICASE AB Riboviruses (RNA viruses without DNA replication intermediates) are the most abundant pathogens infecting animals and plants. Only a few riboviral infections can be controlled with antiviral drugs, mainly because of the rapid appearance of resistance mutations. Little reliable information is available concerning i) kinds and relative frequencies of mutations (the mutational spectrum), ii) mode of genome replication and mutation accumulation, and iii) rates of spontaneous mutation. To illuminate these issues, we developed a model in vivo system based on phage Q beta infecting its natural host, Escherichia coli. The Q beta RT gene encoding the Read-Through protein was used as a mutation reporter. To reduce uncertainties in mutation frequencies due to selection, the experimental Q beta populations were established after a single cycle of infection and selection against RT-mutants during phage growth was ameliorated by plasmid-based RT complementation in trans. The dynamics of Q beta genome replication were confirmed to reflect the linear process of iterative copying (the stamping-machine mode). A total of 32 RT mutants were detected among 7,517 Q beta isolates. Sequencing analysis of 45 RT mutations revealed a spectrum dominated by 39 transitions, plus 4 transversions and 2 indels. A clear template.primer mismatch bias was observed: A.C>C.A>U.G>G.U> transversion mismatches. The average mutation rate per base replication was approximate to 9.1x10(-6) for base substitutions and approximate to 2.3x10(-7) for indels. The estimated mutation rate per genome replication, mu(g), was approximate to 0.04 (or, per phage generation, approximate to 0.08), although secondary RT mutations arose during the growth of some RT mutants at a rate about 7-fold higher, signaling the possible impact of transitory bouts of hypermutation. These results are contrasted with those previously reported for other riboviruses to depict the current state of the art in riboviral mutagenesis.

TI Brain-Specific Rescue of Clock Reveals System-Driven Transcriptional Rhythms in Peripheral Tissue SO PLOS GENETICS LA English DT Article ID CIRCADIAN GENE-EXPRESSION; MAMMALIAN-CELLS; MOUSE-LIVER; SUPRACHIASMATIC NUCLEUS; MICROARRAY ANALYSIS; MESSENGER-RNAS; KEY PATHWAYS; MUTANT MICE; DROSOPHILA; ACTIVATION AB The circadian regulatory network is organized in a hierarchical fashion, with a central oscillator in the suprachiasmatic nuclei (SCN) orchestrating circadian oscillations in peripheral tissues. The nature of the relationship between central and peripheral oscillators, however, is poorly understood. We used the tetOFF expression system to specifically restore Clock function in the brains of Clock(Delta 19) mice, which have compromised circadian clocks. Rescued mice showed normal locomotor rhythms in constant darkness, with activity period lengths approximating wildtype controls. We used microarray analysis to assess whether brain-specific rescue of circadian rhythmicity was sufficient to restore circadian transcriptional output in the liver. Compared to Clock mutants, Clock-rescue mice showed significantly larger numbers of cycling transcripts with appropriate phase and period lengths, including many components of the core circadian oscillator. This indicates that the SCN oscillator overcomes local circadian defects and signals directly to the molecular clock. Interestingly, the vast majority of core clock genes in liver were responsive to Clock expression in the SCN, suggesting that core clock genes in peripheral tissues are intrinsically sensitive to SCN cues. Nevertheless, most circadian output in the liver was absent or severely low-amplitude in Clock-rescue animals, demonstrating that the majority of peripheral transcriptional rhythms depend on a fully functional local circadian oscillator. We identified several new system-driven rhythmic genes in the liver, including Alas1 and Mfsd2. Finally, we show that 12-hour transcriptional rhythms (i.e., circadian "harmonics'') are disrupted by Clock loss-of-function. Brain-specific rescue of Clock converted 12-hour rhythms into 24-hour rhythms, suggesting that signaling via the central circadian oscillator is required to generate one of the two daily peaks of expression. Based on these data, we conclude that 12-hour rhythms are driven by interactions between central and peripheral circadian oscillators.

TI FANCJ/BACH1 Acetylation at Lysine 1249 Regulates the DNA Damage Response SO PLOS GENETICS LA English DT Article ID CROSS-LINK REPAIR; FANCONI-ANEMIA; HELICASE BRIP1; BREAST-CANCER; END RESECTION; PROTEIN; BRCA1; BACH1; PROMOTES; RECOMBINATION AB BRCA1 promotes DNA repair through interactions with multiple proteins, including CtIP and FANCJ (also known as BRIP1/BACH1). While CtIP facilitates DNA end resection when de-acetylated, the function of FANCJ in repair processing is less well defined. Here, we report that FANCJ is also acetylated. Preventing FANCJ acetylation at lysine 1249 does not interfere with the ability of cells to survive DNA interstrand crosslinks (ICLs). However, resistance is achieved with reduced reliance on recombination. Mechanistically, FANCJ acetylation facilitates DNA end processing required for repair and checkpoint signaling. This conclusion was based on the finding that FANCJ and its acetylation were required for robust RPA foci formation, RPA phosphorylation, and Rad51 foci formation in response to camptothecin (CPT). Furthermore, both preventing and mimicking FANCJ acetylation at lysine 1249 disrupts FANCJ function in checkpoint maintenance. Thus, we propose that the dynamic regulation of FANCJ acetylation is critical for robust DNA damage response, recombination-based processing, and ultimately checkpoint maintenance.

We described recent data fish consumption and CHD mortality from publicly available data. We also measured CHD risk factors and serum levels of marine-derived n-3 and other fatty acids from population-based samples of 1324 men in Iceland, Japan, South Korea, and the US. CHD mortality in men in Iceland was almost 3 times as high as that in Japan and South Korea. Generally, a profile of CHD risk factors in Icelanders compared to Japanese was more favorable. Serum marine-derived n-3 fatty acids in Iceland were significantly lower than in Japan and South Korea but significantly higher than in the US. (C) 2012 Elsevier Ltd. All rights reserved.

Individuals with HIV infection are living longer, but as a group are at greater risk to develop age-related disorders, such as certain cancers, cardiovascular disease, type II diabetes, and cognitive impairment, at earlier ages than non-HIV-infected persons. This premature susceptibility to age-related morbidities reflects a syndrome referred to as accelerated aging, wherein deleterious features associated with aging emerge decades earlier in the setting of chronic HIV infection. A prominent immunological feature of accelerated aging in HIV infection is inflation of cytomegalovirus-specific memory T-cell responses to levels associated with an immune risk phenotype. In the absence of HIV infection, immune risk phenotypes develop in cytomegalovirus-infected octogenarians and signify some degree of immune senescence and an elevated risk for all-cause mortality. Chronic inflammation is a probable factor in health risks conveyed by the immune risk phenotype and in putative relationships between cytomegalovirus infection and the same set of age-related disordets arising in chronic HIV infection. Most HIV-infected individuals are cytomegalovirus-seropositive, both HIV and cytomegalovirus are associated with inflammation-related morbidities, and HIV infection accelerates the development of cytomegalovirus-dependent immunological abnormalities. Therefore, closer investigation of the relationship between cytomegalovirus and age-related morbidities emerging in chronic HIV infection appears warranted. This review summarizes evidence that cytomegalovirus could be an important cofactor in the development of age-related morbidities in HIV infection and discusses research to address underlying mechanisms.

Methods: We used an open-source, data-mining suite to process and classify biomedical citations that point to mostly nonrandomized studies from 2 systematic reviews. We built training and test sets for citation portions and compared classifier performance by considering the value of indexing, various feature sets, and optimization. We conducted our experiments in 2 phases. The design of phase I with no optimization was: 4 classifiers x 3 feature sets x 3 citation portions. Classifiers included k-nearest neighbor, naive Bayes, complement nave Bayes, and evolutionary support vector machine. Feature sets included bag of words, and 2- and 3-term n-grams. Citation portions included titles, titles and abstracts, and full citations with metadata. Phase II with optimization involved a subset of the classifiers, as well as features extracted from full citations, and full citations with overweighted titles. We optimized features and classifier parameters by manually setting information gain thresholds outside of a process for iterative grid optimization with 10-fold cross-validations. We independently tested models on data reserved for that purpose and statistically compared classifier performance on 2 types of feature sets. We estimated the number of citations needed to screen by reviewers during a second pass through a reduced set of citations. Results: In phase I, the evolutionary support vector machine returned the best recall for bag of words extracted from full citations; the best classifier with respect to overall performance was k-nearest neighbor. No classifier attained good enough recall for this task without optimization. In phase II, we boosted performance with optimization for evolutionary support vector machine and complement naive Bayes classifiers. Generalization performance was better for the latter in the independent tests. For evolutionary support vector machine and complement naive Bayes classifiers, the initial retrieval set was reduced by 46% and 35%, respectively. Conclusions: Machine learning classifiers can help identify nonrandomized studies eligible for full-text screening by systematic reviewers. Optimization can markedly improve performance of classifiers. However, generalizability varies with the classifier. The number of citations to screen during a second independent pass through the citations can be substantially reduced. (C) 2012 Elsevier B.V. All rights reserved.

TI Population pharmacokinetic analysis of 17-dimethylaminoethylamino-17-demethoxygeldanamycin (17-DMAG) in adult patients with solid tumors SO CANCER CHEMOTHERAPY AND PHARMACOLOGY LA English DT Article DE 17-dimethylaminoethylamino-17-demethoxygeldanamycin; (17-DMAG); 3-compartment model; Heat shock protein-90; Objective function values ID SHOCK-PROTEIN 90; HSP90; CHAPERONE; RATS AB Purpose To identify sources of exposure variability for the tumor growth inhibitor 17-dimethylaminoethylamino-17-demethoxygeldanamycin (17-DMAG) using a population pharmacokinetic analysis. Methods A total 67 solid tumor patients at 2 centers were given 1 h infusions of 17-DMAG either as a single dose, daily for 3 days, or daily for 5 days. Blood samples were extensively collected and 17-DMAG plasma concentrations were measured by liquid chromatography/mass spectrometry. Population pharmacokinetic analysis of the 17-DMAG plasma concentration with time was performed using nonlinear mixed effect modeling to evaluate the effects of covariates, inter-individual variability, and between-occasion variability on model parameters using a stepwise forward addition then backward elimination modeling approach. The inter-individual exposure variability and the effects of between-occasion variability on exposure were assessed by simulating the 95 % prediction interval of the AUC per dose, AUC(0-24) h, using the final model and a model with no between-occasion variability, respectively, subject to the five day 17-DMAG infusion protocol with administrations of the median observed dose. Results A 3-compartment model with first order elimination (ADVAN11, TRANS4) and a proportional residual error, exponentiated inter-individual variability and between occasion variability on Q2 and V1 best described the 17-DMAG concentration data. No covariates were statistically significant. The simulated 95% prediction interval of the AUC(0-24) h for the median dose of 36 mg/m(2) was 1,059-9,007 mg/L h and the simulated 95 % prediction interval of the AUC(0-24) h considering the impact of between-occasion variability alone was 2,910-4,077 mg/L h. Conclusions Population pharmacokinetic analysis of 17-DMAG found no significant covariate effects and considerable inter-individual variability; this implies a wide range of exposures in the population and which may affect treatment outcome. Patients treated with 17-DMAG may require therapeutic drug monitoring which could help achieve more uniform exposure leading to safer and more effective therapy.

TI The "survivin suppressants" NSC 80467 and YM155 induce a DNA damage response SO CANCER CHEMOTHERAPY AND PHARMACOLOGY LA English DT Article DE YM155; NSC 80467; Survivin; DNA damage; cH2AX; pKAP1 ID CELL-LINES; CANCER; DRUGS AB Purpose To establish whether NSC80467, a novel fused naphthquinone imidazolium, has a similar spectrum of activity to the well-characterized "survivin suppressant" YM155 and to extend mechanistic studies for this structural class of agent. Methods NSC80467 and YM155 were analyzed in parallel using assays measuring viability, survivin suppression, inhibition of DNA/RNA/protein synthesis and the cellular response to DNA damage. Results GI(50) values generated for both compounds in the NCI-60 screen yielded a correlation coefficient of 0.748, suggesting significant concordance. Both agents were also shown to inhibit protein expression of survivin [BIRC5]. COMPARE analysis identified DNA damaging agents chromomycin A3 and bisantrene HCl and one DNA-directed inhibitor of transcription, actinomycin D, as correlating with the activity of NSC80467 and YM155. Furthermore, both agents were shown to preferentially inhibit DNA, over RNA and protein synthesis. Thus, the ability of NSC80467 and YM155 to induce a DNA damage response was examined further. Treatment of PC3 cells with either agent resulted in dose-dependent induction of gamma H2AX and pKAP1, two markers of DNA damage. The concentrations of agent required to stimulate gamma H2AX were considerably lower than those required to inhibit survivin, implicating DNA damage as an initiating event. The DNA damage response was then confirmed in a panel of cell lines treated with NSC80467 or YM155, suggesting that gamma H2AX and pKAP1 have potential as response biomarkers. Conclusions These data provide the first evidence that NSC80467 and YM155 are DNA damaging agents where suppression of survivin is a secondary event, likely a consequence of transcriptional repression.

TI A Human Papillomavirus (HPV) In Vitro Neutralization Assay That Recapitulates the In Vitro Process of Infection Provides a Sensitive Measure of HPV L2 Infection-Inhibiting Antibodies SO CLINICAL AND VACCINE IMMUNOLOGY LA English DT Article ID MINOR CAPSID PROTEIN; VIRUS-LIKE PARTICLES; HEPARAN-SULFATE; N-TERMINUS; FURIN; CELLS; MECHANISMS; VACCINES; BINDING; IMMUNIZATION AB Papillomavirus L2-based vaccines have generally induced low-level or undetectable neutralizing antibodies in standard in vitro assays yet typically protect well against in vivo experimental challenge in animal models. Herein we document that mice vaccinated with an L2 vaccine comprising a fusion protein of the L2 amino acids 11 to 88 of human papillomavirus type 16 (HPV16), HPV18, HPV1, HPV5, and HPV6 were uniformly protected from cervicovaginal challenge with HPV16 pseudovirus, but neutralizing antibodies against HPV16, -31, -33, -45, or -58 were rarely detected in their sera using a standard in vitro neutralization assay. To address this discrepancy, we developed a neutralization assay based on an in vitro infectivity mechanism that more closely mimics the in vivo infectious process, specifically by spaciotemporally separating primary and secondary receptor engagement and correspondingly by altering the timing of exposure of the dominant L2 cross-neutralizing epitopes to the antibodies. With the new assay, titers in the 100 to 10,000 range were measured for most sera, whereas undetectable neutralizing activities were observed with the standard assay. In vitro neutralizing titers measured in the serum of mice after passive transfer of rabbit L2 immune serum correlated with protection from cervicovaginal challenge of the mice. This "L2-based" in vitro neutralization assay should prove useful in critically evaluating the immunogenicity of L2 vaccine candidates in preclinical studies and future clinical trials.

While much insight has been gained into the function of the Werner (WRN) and Bloom syndrome proteins (BLM), little is known about RECQL5. We have analyzed the recruitment and retention dynamics of RECQL5 at laser-induced DNA double strand breaks (DSBs) relative to other human RecQ helicases. RECQL5-depleted cells accumulate persistent 53BP1 foci followed by gamma-irradiation, indicating a potential role of RECQL5 in the processing of DSBs. Real time imaging of live cells using confocal laser microscopy shows that RECQL5 is recruited early to laser-induced DSBs and remains for a shorter duration than BLM and WRN, but persist longer than RECQL4. These studies illustrate the differential involvement of RecQ helicases in the DSB repair process. Mapping of domains within RECQL5 that are necessary for recruitment to DSBs revealed that both the helicase and KIX domains are required for DNA damage recognition and stable association of RECQL5 to the DSB sites. Previous studies have shown that MRE11 is essential for the recruitment of RECQL5 to the DSB sites. Here we show that the recruitment of RECQL5 does not depend on the exonuclease activity of MRE11 or on active transcription by RNA polymerase II, one of the prominent interacting partners of RECQL5. Also, the recruitment of RECQL5 to laser-induced damage sites is independent of the presence of other DNA damage signaling and repair proteins BLM, WRN and ATM. Published by Elsevier B.V.

We show that systematic errors in such measurements can be far larger than the statistical error derived from either the observed signal-to-noise ratio, or from the reproducibility of the measurement. Unless special precautions are taken, the problem of systematic errors is shown to be particularly acute in perdeuterated systems, and even more so when TROSY instead of HSQC elements are used to read out the N-15 magnetization through the NMR-sensitive H-1 nucleus. A discussion of the most common sources of systematic errors is presented, as well as TROSY-based pulse schemes that appear free of systematic errors to the level of < 1 %. Application to the small perdeuterated protein GB3, which yields exceptionally high S/N and therefore is an ideal test molecule for detection of systematic errors, yields relaxation rates that show considerably less residue by residue variation than previous measurements. Measured R-2'/R-1' ratios fit an axially symmetric diffusion tensor with a Pearson's correlation coefficient of 0.97, comparable to fits obtained for backbone amide RDCs to the Saupe matrix.

Our goal was to develop a decision support system (DSS) for detecting and localizing peripheral zone prostate cancers by using machine learning approach to calculate a cancer probability map from multiparametric MR images (MP-MRI). Methods: This IRB approved Health Insurance Portability and Accountability Act compliant retrospective study consisted of 31 patients (mean age and serum prostate specific antigen of 60.4 and 6.62 ng/ml, respectively) who had MP-MRI at 3 T followed by radical prostatectomy. Seven patients were excluded due to technical issues with their MP-MRI (e.g., motion artifact, failure to perform all sequences). Cancer and normal regions were identified in the peripheral zone by correlating them to whole mount histology slides of the excised prostatectomy specimens. To facilitate the correlation, tissue blocks matching the MR slices were obtained using a MR-based patient-specific mold. Segmented regions on the MP-MRI were correlated to histopathology and used as training sets for the learning system that generated the cancer probability maps. Leave-one-patient-out cross-validation on the cancer and normal regions was performed to determine the learning system's efficacy, an evolutionary strategies approach (also known as a genetic algorithm) was used to find the optimal values for a set of parameters, and finally a cancer probability map was generated. Results: For the 24 patients that were used in the study, 225 cancer and 264 noncancerous regions were identified from the region maps. The efficacy of DSS was first determined without optimizing support vector machines (SVM) parameters, where a region having a cancer probability greater than or equal to 50% was considered as a correct classification. The nonoptimized system had an f-measure of 85% and the Kappa coefficient of 71% (Rater's agreement, where raters are DSS and ground truth histology). The efficacy of the DSS after optimizing SVM parameters using a genetic algorithm had an f-measure of 89% and a Kappa coefficient of 80%. Thus, after optimization of the DSS there was a 4% increase in the f-measure and a 9% increase in the Kappa coefficient. Conclusions: This DSS provides a cancer probability map for peripheral zone prostate tumors based on endorectal MP-MRI. These cancer probability maps can potentially aid radiologists in accurately localizing peripheral zone prostate cancers for planning targeted biopsies, focal therapy, and follow up for active surveillance.

While IVA inhibits I-f, this effect has been reported at essentially unphysiological voltages, i.e., those more negative than the spontaneous diastolic depolarization (DD) between action potentials (APs). We tested the relative potency of IVA to block I-f over a wide range of membrane potentials, including those that encompass DD governing to the SANC spontaneous firing rate. A clinically relevant IVA concentration of 3 mu M to single, isolated rabbit SANC slowed the spontaneous AP firing rate by 15%. During voltage clamp the maximal I-f was 18 +/- 3 pA/pF (at -120 mV) and the maximal I-f reduction by IVA was 60 +/- 8% observed at -92 +/- 4 mV. At the maximal diastolic depolarization (similar to-60 mV) I-f amplitude was only -2.9 +/- 0.4 pA/pF, and was reduced by only 41 +/- 6% by IVA. Thus, I-f amplitude and its inhibition by IVA at physiologically relevant membrane potentials are substantially less than that at unphysiological (hyperpolarized) membrane potentials. This novel finding more accurately describes how IVA affects SANC function and is of direct relevance to numerical modeling of SANC automaticity.

TI The Evolutionary Consequences of Blood-Stage Vaccination on the Rodent Malaria Plasmodium chabaudi SO PLOS BIOLOGY LA English DT Article ID APICAL MEMBRANE ANTIGEN-1; PAPUA-NEW-GUINEA; BORDETELLA-PERTUSSIS STRAINS; MAREKS-DISEASE VACCINES; WITHIN-HOST COMPETITION; IMMUNOGENICITY TRIAL; POPULATION-STRUCTURE; VIRULENCE EVOLUTION; PROTECTIVE IMMUNITY; TEMPORAL TRENDS AB Malaria vaccine developers are concerned that antigenic escape will erode vaccine efficacy. Evolutionary theorists have raised the possibility that some types of vaccine could also create conditions favoring the evolution of more virulent pathogens. Such evolution would put unvaccinated people at greater risk of severe disease. Here we test the impact of vaccination with a single highly purified antigen on the malaria parasite Plasmodium chabaudi evolving in laboratory mice. The antigen we used, AMA-1, is a component of several candidate malaria vaccines currently in various stages of trials in humans. We first found that a more virulent clone was less readily controlled by AMA-1-induced immunity than its less virulent progenitor. Replicated parasites were then serially passaged through control or AMA-1 vaccinated mice and evaluated after 10 and 21 rounds of selection. We found no evidence of evolution at the ama-1 locus. Instead, virulence evolved; AMA-1-selected parasites induced greater anemia in naive mice than both control and ancestral parasites. Our data suggest that recombinant blood stage malaria vaccines can drive the evolution of more virulent malaria parasites. C1 [Barclay, Victoria C.; Sim, Derek; Chan, Brian H.

TI Heme Uptake by Leishmania amazonensis Is Mediated by the Transmembrane Protein LHR1 SO PLOS PATHOGENS LA English DT Article ID VISCERAL LEISHMANIASIS; MEXICANA-AMAZONENSIS; GENE-EXPRESSION; BIOSYNTHESIS; BINDING; CELLS; IDENTIFICATION; HEMOGLOBIN; TRANSPORT; YEAST AB Trypanosomatid protozoan parasites lack a functional heme biosynthetic pathway, so must acquire heme from the environment to survive. However, the molecular pathway responsible for heme acquisition by these organisms is unknown. Here we show that L. amazonensis LHR1, a homolog of the C. elegans plasma membrane heme transporter HRG-4, functions in heme transport. Tagged LHR1 localized to the plasma membrane and to endocytic compartments, in both L. amazonensis and mammalian cells. Heme deprivation in L. amazonensis increased LHR1 transcript levels, promoted uptake of the fluorescent heme analog ZnMP, and increased the total intracellular heme content of promastigotes. Conversely, deletion of one LHR1 allele reduced ZnMP uptake and the intracellular heme pool by approximately 50%, indicating that LHR1 is a major heme importer in L. amazonensis. Viable parasites with correct replacement of both LHR1 alleles could not be obtained despite extensive attempts, suggesting that this gene is essential for the survival of promastigotes. Notably, LHR1 expression allowed Saccharomyces cerevisiae to import heme from the environment, and rescued growth of a strain deficient in heme biosynthesis. Syntenic genes with high sequence identity to LHR1 are present in the genomes of several species of Leishmania and also Trypanosoma cruzi and Trypanosoma brucei, indicating that therapeutic agents targeting this transporter could be effective against a broad group of trypanosomatid parasites that cause serious human disease.

Recently, it was shown that NK cell-mediated immune pressure can result in the selection of HIV-1 escape mutations. A potential mechanism for this NK cell escape is the selection of HLA class I-presented HIV-1 epitopes that allow for the engagement of inhibitory killer cell immunoglobulin-like receptors (KIRs), notably KIR2DL2. We therefore investigated the consequences of sequence variations within HLA-Cw*0102-restricted epitopes on the interaction of HLA-Cw* 0102 with KIR2DL2 using a large panel of overlapping HIV-1 p24 Gag peptides. 217 decameric peptides spanning the HIV-1 p24 Gag consensus sequence were screened for HLA-Cw* 0102 stabilization by co-incubation with Cw*0102(+)/TAP-deficient T2 cells using a flow cytometry-based assay. KIR2DL2 binding was assessed using a KIR2DL2-IgG fusion construct. Function of KIR2DL2(+) NK cells was flow cytometrically analyzed by measuring degranulation of primary NK cells after co-incubation with peptide-pulsed T2 cells. We identified 11 peptides stabilizing HLA-Cw* 0102 on the surface of T2 cells. However, only one peptide (p24 Gag(209-218) AAEWDRLHPV) allowed for binding of KIR2DL2. Notably, functional analysis showed a significant inhibition of KIR2DL2(+) NK cells in the presence of p24 Gag(209-21)8-pulsed T2 cells, while degranulation of KIR2DL2(2) NK cells was not affected. Moreover, we demonstrated that sequence variations in position 7 of this epitope observed frequently in naturally occurring HIV-1 sequences can modulate binding to KIR2DL2. Our results show that the majority of HIV-1 p24 Gag peptides stabilizing HLA-Cw* 0102 do not allow for binding of KIR2DL2, but identified one HLA-Cw* 0102-presented peptide (p24 Gag(209-218)) that was recognized by the inhibitory NK cell receptor KIR2DL2 leading to functional inhibition of KIR2DL2-expressing NK cells. Engagement of KIR2DL2 might protect virus-infected cells from NK cell-mediated lysis and selections of sequence polymorphisms that increase avidity to KIR2DL2 might provide a mechanism for HIV-1 to escape NK cell-mediated immune pressure.

Conflicting reports suggest that cellular glycans containing sialic acid (Neu5Ac) may play a role in MCPyV infectious entry. To address this question, we solved X-ray structures of the MCPyV major capsid protein VP1 both alone and in complex with several sialylated oligosaccharides. A shallow binding site on the apical surface of the VP1 capsomer recognizes the disaccharide Neu5Ac-alpha 2,3-Gal through a complex network of interactions. MCPyV engages Neu5Ac in an orientation and with contacts that differ markedly from those observed in other polyomavirus complexes with sialylated receptors. Mutations in the Neu5Ac binding site abolish MCPyV infection, highlighting the relevance of the Neu5Ac interaction for MCPyV entry. Our study thus provides a powerful platform for the development of MCPyV-specific vaccines and antivirals. Interestingly, engagement of sialic acid does not interfere with initial attachment of MCPyV to cells, consistent with a previous proposal that attachment is mediated by a class of non-sialylated carbohydrates called glycosaminoglycans. Our results therefore suggest a model in which sialylated glycans serve as secondary, post-attachment co-receptors during MCPyV infectious entry. Since cell-surface glycans typically serve as primary attachment receptors for many viruses, we identify here a new role for glycans in mediating, and perhaps even modulating, post-attachment entry processes.

Understanding how these ligands influence the structure of Env is of fundamental interest for HIV vaccine development. Using cryo-electron microscopy, we describe the contrasting structural outcomes of trimeric Env binding to soluble CD4, to the broadly neutralizing, CD4-binding site antibodies VRC01, VRC03 and b12, or to the monoclonal antibody 17b, a co-receptor mimic. Binding of trimeric HIV-1 BaL Env to either soluble CD4 or 17b alone, is sufficient to trigger formation of the open quaternary conformation of Env. In contrast, VRC01 locks Env in the closed state, while b12 binding requires a partial opening in the quaternary structure of trimeric Env. Our results show that, despite general similarities in regions of the HIV-1 gp120 polypeptide that contact CD4, VRC01, VRC03 and b12, there are important differences in quaternary structures of the complexes these ligands form on native trimeric Env, and potentially explain differences in the neutralizing breadth and potency of antibodies with similar specificities. From cryo-electron microscopic analysis at similar to 9 angstrom resolution of a cleaved, soluble version of trimeric Env, we show that a structural signature of the open Env conformation is a three-helix motif composed of alpha-helical segments derived from highly conserved, non-glycosylated N-terminal regions of the gp41 trimer. The three N-terminal gp41 helices in this novel, activated Env conformation are held apart by their interactions with the rest of Env, and are less compactly packed than in the post-fusion, six-helix bundle state. These findings suggest a new structural template for designing immunogens that can elicit antibodies targeting HIV at a vulnerable, pre-entry stage. C1 [Tran, Erin E.

TI Development of a database of organ doses for paediatric and young adult CT scans in the United Kingdom SO RADIATION PROTECTION DOSIMETRY LA English DT Article ID MONTE-CARLO SIMULATIONS; HELICAL CT; CANCER; BODY; DOSIMETRY; PROGRAM; MODELS; RISKS AB Despite great potential benefits, there are concerns about the possible harm from medical imaging including the risk of radiation-related cancer. There are particular concerns about computed tomography (CT) scans in children because both radiation dose and sensitivity to radiation for children are typically higher than for adults undergoing equivalent procedures. As direct empirical data on the cancer risks from CT scans are lacking, the authors are conducting a retrospective cohort study of over 240 000 children in the UK who underwent CT scans. The main objective of the study is to quantify the magnitude of the cancer risk in relation to the radiation dose from CT scans. In this paper, the methods used to estimate typical organ-specific doses delivered by CT scans to children are described. An organ dose database from Monte Carlo radiation transport-based computer simulations using a series of computational human phantoms from newborn to adults for both male and female was established. Organ doses vary with patient size and sex, examination types and CT technical settings. Therefore, information on patient age, sex and examination type from electronic radiology information systems and technical settings obtained from two national surveys in the UK were used to estimate radiation dose. Absorbed doses to the brain, thyroid, breast and red bone marrow were calculated for reference male and female individuals with the ages of newborns, 1, 5, 10, 15 and 20 y for a total of 17 different scan types in the pre- and post-2001 time periods. In general, estimated organ doses were slightly higher for females than males which might be attributed to the smaller body size of the females. The younger children received higher doses in pre-2001 period when adult CT settings were typically used for children. Paediatric-specific adjustments were assumed to be used more frequently after 2001, since then radiation doses to children have often been smaller than those to adults. The database here is the first detailed organ-specific paediatric CT scan database for the UK. As well as forming the basis for the UK study, the results and description of the methods will also serve as a key resource for paediatric CT scan studies currently underway in other countries.

TI A High-Throughput Screen To Identify Inhibitors of ATP Homeostasis in Non-replicating Mycobacterium tuberculosis SO ACS CHEMICAL BIOLOGY LA English DT Article ID HYPOXIC RESPONSE; BOVIS BCG; GENE; PERSISTENCE; SYNTHASE; PYRAZINAMIDE; ADAPTATION; METABOLISM; RESISTANCE; DORMANCY AB Growing evidence suggests that the presence of a subpopulation of hypoxic non-replicating, phenotypically drug-tolerant mycobacteria is responsible for the prolonged duration of tuberculosis treatment. The discovery of new antitubercular agents active against this subpopulation may help in developing new strategies to shorten the time of tuberculosis therapy. Recently, the maintenance of a low level of bacterial respiration was shown to be a point of metabolic vulnerability in Mycobacterium tuberculosis. Here, we describe the development of a hypoxic model to identify compounds targeting mycobacterial respiratory functions and ATP homeostasis in whole mycobacteria. The model was adapted to 1,536-well plate format and successfully used to screen over 600,000 compounds. Approximately 800 compounds were confirmed to reduce intracellular ATP levels in a dose-dependent manner in Mycobacterium bovis BCG. One hundred and forty non-cytotoxic compounds with activity against hypoxic non-replicating M. tuberculosis were further validated. The resulting collection of compounds that disrupt ATP homeostasis in M. tuberculosis represents a valuable resource to decipher the biology of persistent mycobacteria. C1 [Rao, Srinivasa P.

Consequently, excess PMP22 resulting from its genetic duplication and overexpression has been directly associated with the peripheral neuropathy called Charcot-Marie-Tooth disease type 1A (CMT1A), the most prevalent type of CMT. Here, in an attempt to identify transcriptional inhibitors with therapeutic value toward CMT1A, we developed a cross-validating pair of orthogonal reporter assays, firefly luciferase (FLuc) and beta-lactamase (beta Lac), capable of recapitulating PMP22 expression, utilizing the intronic regulatory element of the human PMP22 gene. Each compound from a collection of approximately 3,000 approved drugs was tested at multiple titration points to achieve a pharmacological end point in a 1536-well plate quantitative high-throughput screen (qHTS) format. In conjunction with an independent counter-screen for cytotoxicity, the design of our orthogonal screen platform effectively contributed to selection and prioritization of active compounds, among which three drugs (fenretinide, olvanil, and bortezomib) exhibited marked reduction of endogenous Pmp22 mRNA and protein. Overall, the findings of this study provide a strategic approach to assay development for gene-dosage diseases such as CMT1A.

TI Ceramide mediates nanovesicle shedding and cell death in response to phosphatidylinositol ether lipid analogs and perifosine SO CELL DEATH & DISEASE LA English DT Article DE Akt; nanovesicle; sphingomyelinase; ceramide; perifosine ID SYNERGISTICALLY INDUCES APOPTOSIS; TUMOR-DERIVED EXOSOMES; CANCER-CELLS; MULTIVESICULAR ENDOSOMES; ACID SPHINGOMYELINASE; LEUKEMIA-CELLS; AKT INHIBITOR; MICROVESICLES; EXPRESSION; VESICLES AB Anticancer phospholipids that inhibit Akt such as the alkylphospholipid perifosine (Per) and phosphatidylinositol ether lipid analogs (PIAs) promote cellular detachment and apoptosis and have a similar cytotoxicity profile against cancer cell lines in the NCI60 panel. While investigating the mechanism of Akt inhibition, we found that short-term incubation with these compounds induced rapid shedding of cellular nanovesicles containing EGFR, IGFR and p-Akt that occurred in vitro and in vivo, while prolonged incubation led to cell detachment and death that depended on sphingomyelinase-mediated generation of ceramide. Pretreatment with sphingomyelinase inhibitors blocked ceramide generation, decreases in phospho-Akt, nanovesicle release and cell detachment in response to alkylphospholipids and PIAs in non-small cell lung cancer cell lines. Similarly, exogenous ceramide also decreased active Akt and induced nanovesicle release. Knockdown of neutral sphingomyelinase decreased, whereas overexpression of neutral or acid sphingomyelinase increased cell detachment and death in response to the compounds. When transferred in vitro, PIA or Per-induced nanovesicles increased ceramide levels and death in recipient cells. These results indicate ceramide generation underlies the Akt inhibition and cytotoxicity of this group of agents, and suggests nanovesicle shedding and uptake might potentially propagate their cytotoxicity in vivo.

Nelfinavir (NFV) is an HIV protease inhibitor that induces endoplasmic reticulum (ER) stress in cancer cells. Under conditions of ER stress, misfolded proteins are transported from the ER back to the cytosol for subsequent degradation by the ubiquitin-proteasome system. Bortezomib (BZ) is a proteasome inhibitor and interferes with degradation of misfolded proteins. Here, we show that NFV and BZ enhance proteotoxicity in non-small cell lung cancer (NSCLC) and multiple myeloma (MM) cells. The combination synergistically inhibited cell proliferation and induced cell death. Activating transcription factor (ATF)3 and CCAAT-enhancer binding protein homologous protein (CHOP), markers of ER stress, were rapidly increased, and their siRNA-mediated knockdown inhibited cell death. Knockdown of double-stranded RNA activated protein kinase-like ER kinase, a signal transducer in ER stress, significantly decreased apoptosis. Pretreatment with the protein synthesis inhibitor, cycloheximide, decreased levels of ubiquitinated proteins, ATF3, CHOP, and the overall total cell death, suggesting that inhibition of protein synthesis increases cell survival by relieving proteotoxic stress. The NFV/BZ combination inhibited the growth of NSCLC xenografts, which correlated with the induction of markers of ER stress and apoptosis. Collectively, these data show that NFV and BZ enhance proteotoxicity in NSCLC and MM cells, and suggest that this combination could tip the precarious balance of protein homeostasis in cancer cells for therapeutic gain.

GISTIC algorithm revealed the presence of 126 significant peaks of CN aberration, which included 13 cancer-related genes. Among these peaks, CN gain of BCL2 and CN loss of CDKN2A/B were the only genes in the respective regions of CN aberration and were associated with poor outcome. TET cell lines were sensitive to siRNA knockdown of the anti-apoptotic molecules BCL2 and MCL1. Gx15-070, a pan-BCL2 inhibitor, induced autophagy-dependent necroptosis in TET cells via a mechanism involving mTOR pathways, and inhibited TET xenograft growth. ABT263, an inhibitor of BCL2/BCL-XL/BCL-W, reduced proliferation in TET cells when administered in combination with sorafenib, a tyrosine kinase inhibitor able to downregulate MCL1. Immunohistochemistry on 132 TETs demonstrated that CN loss of CDKN2A correlated with lack of expression of its related protein p16 INK4 and identified tumors with poor prognosis. The molecular markers BCL2 and CDKN2A may be of potential value in diagnosis and prognosis of TETs. Our study provides the first preclinical evidence that deregulated anti-apoptotic BCL2 family proteins may represent suitable targets for TET treatment.

To identify molecular pathways that might be associated with these disorders, we evaluated 38 HIV-infected and 35 uninfected subjects over 18-months for intracellular cytokine levels, sleep patterns and duration of sleep, and neurodevelopmental abilities. HIV infection was significantly associated with alterations of intracellular pro-inflammatory cytokines (TNF-alpha, IFN-gamma, IL-12), sleep factors (total time asleep and daytime sleep patterns), and neurocognitive factors (parent and patient reported problems with socio-emotional, behavioral, and executive functions; working memory-mental fatigue; verbal memory; and sustained concentration and vigilance. By better defining the relationships between HIV infection, sleep disturbances, and poor psychosocial behavior and neurocognition, it may be possible to provide targeted pharmacologic and procedural interventions to improve these debilitating conditions.

Studies of Stn have indicated both positive and negative effects on Salmonella virulence. In this study, we attempted to evaluate Stn function and its effects on Salmonella virulence. To investigate Stn function, we first performed in vitro and in vivo analysis using mammalian cells and a murine ileal loop model. In these systems, we did not observe differences in virulence phenotypes between wild-type Salmonella and an stn gene-deleted mutant. We next characterized the phenotypes and molecular properties of the mutant strain under various in vitro conditions. The proteomic profiles of the total cell membrane protein fraction differed between wild type and mutant in that there was an absence of a protein in the mutant strain, which was identified as OnnpA. By far-western blotting, OmpA was found to interact directly with Stn. To verify this result, the morphology of Salmonella was examined by transmission electron microscopy, with OmpA localization being analyzed by immunogold labeling. Compared with wild-type Salmonella, the mutant strain had a different pole structure and a thin periplasmic space; OmpA was not seen in the mutant. These results indicate that Stn, via regulation of OmpA membrane localization, functions in the maintenance of membrane composition and integrity.

Of patients presenting with HF, 3055 have a preserved ejection fraction (HFPEF) rather than a reduced ejection fraction (HFREF). Our objective was to examine discriminating clinical features in new-onset HFPEF vs. HFREF. Of 712 participants in the Framingham Heart Study (FHS) hospitalized for new-onset HF between 1981 and 2008 (median age 81 years, 53 female), 46 had HFPEF (EF 45) and 54 had HFREF (EF 45). In multivariable logistic regression, coronary heart disease (CHD), higher heart rate, higher potassium, left bundle branch block, and ischaemic electrocardiographic changes increased the odds of HFREF; female sex and atrial fibrillation increased the odds of HFPEF. In aggregate, these clinical features predicted HF subtype with good discrimination (c-statistic 0.78). Predictors were examined in the Enhanced Feedback for Effective Cardiac Treatment (EFFECT) study. Of 4436 HF patients (median age 75 years, 47 female), 32 had HFPEF and 68 had HFREF. Distinguishing clinical features were consistent between FHS and EFFECT, with comparable discrimination in EFFECT (c-statistic 0.75). In exploratory analyses examining the traits of the intermediate EF group (EF 3555), CHD predisposed to a decrease in EF, whereas other clinical traits showed an overlapping spectrum between HFPEF and HFREF. Multiple clinical characteristics at the time of initial HF presentation differed in participants with HFPEF vs. HFREF. While CHD was clearly associated with a lower EF, overlapping characteristics were observed in the middle of the left ventricular EF range spectrum.

Objective: The objective of this study was to investigate the cross-reactivity between a major glutathione-S transferase allergen of cockroach (Bla g 5) and the glutathione-S transferase of Wuchereria bancrofti (WbGST), a major lymphatic filarial pathogen of humans. Methods: We compared the molecular and structural similarities between Bla g 5 and WbGST by in silico analysis and by linear epitope mapping. The levels of IgE, IgG, and IgG(4) antibodies were measured in filarial-infected and filarial-uninfected patients. Mice were infected with Heligmosomoides bakeri, and their skin was tested for cross-reactive allergic responses. Results: These 2 proteins are 30% identical at the amino acid level with remarkable similarity in the N-terminal region and overall structural conservation based on predicted 3-dimensional models. Filarial infection was associated with IgE, IgG, and IgG(4) anti-Bla g 5 antibody production, with a significant correlation between antibodies (irrespective of isotype) to Bla g 5 and WbGST (P < .0003). Preincubation of sera from cockroach-allergic subjects with WbGST partially depleted (by 50%-70%) anti-Bla g 5 IgE, IgG, and IgG(4) antibodies. IgE epitope mapping of Bla g 5 revealed that 2 linear N-terminal epitopes are highly conserved in WbGST corresponding to Bla g 5 peptides partially involved in the inhibition of WbGST binding. Finally, mice infected with H bakeri developed anti-HbGST IgE and showed immediate-type skin test reactivity to Bla g 5. Conclusion: These data demonstrate that helminth glutathione-S transferase and the aeroallergen Bla g 5 share epitopes that can induce allergic cross-sensitization.

To evaluate the PLD induction potential, 4,161 nonredundant drug-like molecules from the National Institutes of Health Chemical Genomics Center (NCGC) Pharmaceutical Collection (NPC), the Library of Pharmacologically Active Compounds (LOPAC), and the Tocris Biosciences collection were screened in a quantitative high-throughput screening (qHTS) format. The potential of drug-lipid complex formation can be linked directly to the structures of drug molecules, and many PLD inducing drugs were found to share common structural features. Support vector machine (SVM) models were constructed by using customized atom types or Molecular Operating Environment (MOE) 2D descriptors as structural descriptors. Either the compounds from LOPAC or randomly selected from the entire data set were used as the training set. The impact of training data with biased structural features and the impact of molecule descriptors emphasizing whole-molecule properties or detailed functional groups at the atom level on model performance were analyzed and discussed. Rebalancing strategies were applied to improve the predictive power of the SVM models. Using the undersampling method, the consensus model using one-third of the compounds randomly selected from the data set as the training set achieved high accuracy of 0.90 in predicting the remaining two-thirds of the compounds constituting the test set, as measured by the area under the receiver operator characteristic curve (AUC-ROC).

Juvenile zebrafish (n = 20; 5.06 +/- 0.69 mg) were stocked into each of 24 tanks (volume, 2 L); 3 tanks were assigned to each of 8 feeding combinations for a period of 60 d. At the end of 60 d, 2 male and 2 female fish from each tank were pooled by dietary treatment (n = 6) and used to evaluate the effects of feeding combinations on early reproductive performance. Zebrafish fed dietary treatments 3 and 7 had significantly greater weight gain than zebrafish fed diet 5. Mean spawning success was significantly greater in zebrafish fed the control diet (Artemia only) than in those fed diet 1. Mean hatch rates were greater in zebrafish fed the control feed and diets 1, 2, 3, 5, and 6 than zebrafish fed diet 4. Additional results suggest that female zebrafish are sexually mature after 90 d post fertilization and that fertilization rates are the limiting factor in early reproduction.

We examined whether cognitive training was associated with reduced rate of incident dementia. Participants were from the Advanced Cognitive Training for Independent and Vital Elderly (ACTIVE) study (n = 2,802). Incident dementia was defined using a combination of interview- and performance-based methods. Survival analysis was used to determine if ACTIVE treatment affected the rate of incident dementia during 5 years of follow-up. A total of 189 participants met criteria for incident dementia. Baseline factors predictive of incident dementia were older age, male gender, African American race, fewer years of education, relationship other than married, no alcohol use, worse MMSE, worse SF-36 physical functioning, higher depressive symptomatology, diabetes, and stroke (all p < .05). A multivariable model with significant predictors of incident dementia and training group revealed that cognitive training was not associated with a lower rate of incident dementia. Cognitive training did not affect rates of incident dementia after 5 years of follow-up. Longer follow-up or enhanced training may be needed to fully explore the preventive capacity of cognitive training in forestalling onset of dementia.

Presenting Test Results in Electronic Medical Records SO MEDICAL DECISION MAKING LA English DT Article DE electronic personal health record; medical test results; format; usability ID HEALTH-CARE PROVIDERS; QUANTITATIVE INFORMATION; TREATMENT DECISIONS; RISK; FORMATS; PERCEPTION; INTERNET; IMPACT AB Background. Electronic personal health records offer a promising way to communicate medical test results to patients. We compared the usability of tables and horizontal bar graphs for presenting medical test results electronically. Methods. We conducted experiments with a convenience sample of 106 community-dwelling adults. In the first experiment, participants viewed either table or bar graph formats (between subjects) that presented medical test results with normal and abnormal findings. In a second experiment, participants viewed table and bar graph formats (within subjects) that presented test results with normal, borderline, and abnormal findings. Results. Participants required less viewing time when using bar graphs rather than tables. This overall difference was due to superior performance of bar graphs in vignettes with many test results. Bar graphs and tables performed equally well with regard to recall accuracy and understanding. In terms of ease of use, participants did not prefer bar graphs to tables when they viewed only one format. When participants viewed both formats, those with experience with bar graphs preferred bar graphs, and those with experience with tables found bar graphs equally easy to use. Preference for bar graphs was strongest when viewing tests with borderline results. Conclusions. Compared to horizontal bar graphs, tables required more time and experience to achieve the same results, suggesting that tables can be a more burdensome format to use. The current practice of presenting medical test results in a tabular format merits reconsideration.

To assess the Mnemonic effects of selective blockade in perirhinal cortex of muscarinic receptor subtypes, we locally infused either the m1-selective antagonist pirenzepine or the m2-selective antagonist methoctramine in animals performing one-trial visual recognition, and compared these scores with those following infusions of equivalent volumes of saline. Compared to these control infusions, injections of pirenzepine, but not of methoctramine, significantly impaired recognition accuracy. Further, similar doses of scopolamine and pirenzepine yielded similar deficits, suggesting that the deficits obtained earlier with scopolamine were due mainly, if not exclusively, to blockade of m1 receptors. The present findings indicate that m1 and m2 receptors have functionally dissociable roles, and that the formation of new visual memories is critically dependent on the cholinergic activation of m1 receptors located on perirhinal cells.

Methods: We performed genome-wide homozygosity mapping, and sequenced all known genes in the one region of extended homozygosity. Quantitative and allele-specific reverse transcriptase PCR (RT-PCR) were performed on a candidate gene to determine the RNA expression level in affected siblings and controls and the relative abundance of the wild-type and mutant alleles in a heterozygote. Results: A region of shared homozygosity at chromosome 13q13.3-13q14.11 was found in 4 affected siblings and 1 unaffected sibling. A homozygous single nucleotide variant was found in the 3'-untranslated region of the ecto-NADH oxidase 1 gene (ENOX1). No other variants likely to be pathogenic were found in genes in this region or elsewhere. The ENOX1 sequence variant was not found in 764 controls. Quantitative RT-PCR showed that expression of ENOX1 decreased to about 20% of normal levels in lymphoblastoid cells from individuals homozygous for the variant and to about 50% in 2 unaffected heterozygotes. Allele-specific RT-PCR showed a 55%-60% reduction in the level of the variant transcript in heterozygous cells due to reduced mRNA stability. Conclusion: These results indicate that this sequence variant in ENOX1 may contribute to the familial autoimmune myasthenia in these patients.

These sites, generally termed specificity determining sites (SDS), might play a crucial role in binding to a specific substrate or proteins. Identification of SDS through experimental techniques is a slow, difficult and tedious job. Hence, it is very important to develop efficient computational methods that can more expediently identify SDS. Herein, we present Specificity prediction using amino acids' Properties, Entropy and Evolution Rate (SPEER)-SERVER, a web server that predicts SDS by analyzing quantitative measures of the conservation patterns of protein sites based on their physico-chemical properties and the heterogeneity of evolutionary changes between and within the protein subfamilies. This web server provides an improved representation of results, adds useful input and output options and integrates a wide range of analysis and data visualization tools when compared with the original standalone version of the SPEER algorithm. Extensive benchmarking finds that SPEER-SERVER exhibits sensitivity and precision performance that, on average, meets or exceeds that of other currently available methods.

Design: Ordinal logistic regression modelling was used to interpret risk. Proportional odds modelling assessed four divisions of ranked CHD risk (4, high; 3, increased; 2, slight; 1, minimal), separately by sex. Setting: Baltimore, MD, USA. Subjects: African-American and white participants (n 1823) from baseline of the Healthy Aging in Neighborhoods of Diversity across the Life Span (HANDLS) study, aged 30-64 years. Results: For men, there was a 0.5% increase in risk for every 10-unit rise in serum ferritin (pmol/l). Other significant predictors included increased BMI, white race, unemployment and C-reactive protein >= 9.5 mg/l. For women, there was a 5.1% increase in risk per 10-unit rise in serum ferritin (pmol/l). Other significant predictors included increased BMI, lower education, unemployment and C-reactive protein mg/l. Conclusions: Serum ferritin is a significant predictor of 10-year hard CHD risk for HANDLS study participants, a low-income, urban population. Serum ferritin, independent of elevated C-reactive protein, was associated with increased 10-year CHD risk for HANDLS participants. To our knowledge, these data provide the first evidence of the role of serum ferritin as a risk factor for hard CHD in African-American and white postmenopausal women in the USA. Future research on cardiovascular events from this prospective study may confirm the association.

Most patients were asymptomatic and diagnosed with gallbladder metastasis on imaging performed for surveillance or staging. The median time to gallbladder metastasis following nephrectomy was 4 years. Metastasis to the gallbladder occurred both synchronously (33%) and metachronously (67%). Of the patients with available histology, all had clear cell RCC (n = 28). Of all patients, 13 (39%) had metastasis only to the gallbladder, while 20 (61%) had additional sites of metastasis. The most common sites of additional metastasis were contralateral kidney (30%), pancreas (21%), lung (18%), adrenal (18%), and lymph nodes (9%). All patients underwent cholecystectomy. At a median follow up time of 1.5 years after cholecystectomy, 54% of patients had no evidence of disease, 14% were alive with metastasis, 23% had died from metastatic RCC, and 9% died from causes unrelated to their cancer. Conclusion: Gallbladder metastasis from RCC is a rare event that may occur synchronously or metachronously with most patients being asymptomatic. Clear cell carcinoma appears to be the primary pathology associated with gallbladder metastasis. High rates of bilateral RCC and pancreatic metastasis suggest novel associations in patients with RCC and gallbladder metastasis. Published by Elsevier Inc.

While significant advances have been made in the diagnosis and treatment of localized disease, androgen deprivation therapy remains the treatment of choice for advanced and metastatic disease. However, once a man progresses on androgen deprivation, therapies targeting castration-resistant CaP have been extremely limited until quite recently. Urologic oncologists who wish to play an active role in the treatment of men with CaP from diagnosis through end-of-life care should be familiar with administration of and toxicities associated with chemotherapeutic agents. This review is directed at urologists and urologic oncologists and will discuss many of the FDA-approved intravenous agents currently available for castration-resistant CaP with a specific focus on the side-effects associated with these regimens.

We previously demonstrated that oviducts of genistein-treated mice are "posteriorized" as compared to control mouse oviducts because they express numerous genes normally restricted to posterior regions of the female reproductive tract (FRT), the cervix and vagina. We report here that neonatal genistein treatment resulted in substantial changes in oviduct expression of genes important for the FRT mucosal immune response, including immunoglobulins, antimicrobials, and chemokines. Some of the altered immune response genes were chronically altered beginning at the time of neonatal genistein treatment, indicating that these alterations were a result of the posteriorization phenotype. Other alterations in oviduct gene expression were observed only in early pregnancy, immediately after the FRT was exposed to inflammatory or antigenic stimuli from ovulation and mating. The oviduct changes affected development of the surviving embryos by increasing the rate of cleavage and decreasing the trophectoderm-to-inner cell mass cell ratio at the blastocyst stage. We conclude that both altered immune responses to pregnancy and deficits in oviduct support for preimplantation embryo development in the neonatal genistein model are likely to contribute to infertility phenotype.

Primary outcomes were vertebral fracture in the osteoporotic population and invasive breast cancer in all study participants. Here, we report the detailed breast cancer findings from the trial. Breast cancers were detected by annual mammograms and clinical examination. After 48 months follow-up, breast cancer incidence was compared between treatment groups by estrogen receptor (ER) and progesterone receptor (PR) status and baseline risk factors. Baseline breast cancer risk factors, including age, estimated Gail risk, and bone mineral density, were well balanced between treatment groups. A total of 75 breast cancers occurred 53 in the placebo group and 22 in the arzoxifene group (HR 0.41, 95 % CI 0.25-0.68, P < 0.001). There were 62 invasive breast cancers, 39 identified as invasive ER-positive (placebo 30, arzoxifene 9; HR 0.30, 95 % CI 0.14-0.63, P = 0.001) and 30 identified as invasive PR-positive (placebo 23, arzoxifene 7; HR 0.30, 95 % CI 0.13-0.71, P = 0.003). Breast cancer risk reduction with arzoxifene was similar between Gail risk groups (P interaction = 0.31) and between low bone mass and osteoporosis groups (P interaction = 0.35). Although generally well tolerated, there was a significant increase in venous thromboembolism, vasomotor symptoms, muscle cramps, and some gynecological events with arzoxifene. These findings demonstrate that in this study arzoxifene reduced the risk of ER-positive breast cancer in this population of postmenopausal women with low bone mass or osteoporosis, an effect similar to that seen with other SERMs. C1 [Powles, Trevor J.] Canc Ctr London Parkside, Breast Unit, London, England.

TI Predictors of functional shoulder recovery at 1 and 12 months after breast cancer surgery SO BREAST CANCER RESEARCH AND TREATMENT LA English DT Article DE Breast cancer; Physical impairment; Arm morbidity; Activities of daily living ID LYMPH-NODE DISSECTION; QUALITY-OF-LIFE; PREOPERATIVE ASSESSMENT ENABLES; AXILLARY WEB SYNDROME; PHYSICAL-ACTIVITY; ARM MORBIDITY; EARLY-DIAGNOSIS; BIOPSY; HEALTH; PHYSIOTHERAPY AB The objective of this study are (1) to determine if upper extremity function, as represented by shoulder ROM, self-reported symptoms and upper extremity functional limitations in activities of daily living could be predictively related to demographic and cancer characteristics post-surgery for breast cancer. And (2) to examine if variables related to early onset impairment contribute to late onset impairments in women after breast cancer surgery. Subjects were assessed preoperatively and 1, 3, 6, 9, and 12+ months post breast cancer surgery for impairments and symptoms and at 12+ months for shoulder functional limitations using a physical therapy surveillance model. Body weight, shoulder ROM, manual muscle testing, and upper limb volume were recorded. At 12+ months, the Harvard Alumni Health Study Physical Activity Questionnaire, and an Upper Limb Disability Questionnaire were administered. Symptoms and ROM impairments were compared by functional limitations. Characteristics significantly associated with early ROM impairment (but not later impairment) were axillary lymph node dissection, removal of a parts per thousand yen15 nodes, mastectomy surgery and stage II breast cancer. Positive nodes, older age, and BMI a parts per thousand yen 25 were significantly associated with reduced shoulder ROM at 12+ months. At 12+ months, only 10 % of the patients experienced ROM impairments while rates of self-reported symptoms in the affected upper extremity at 12+ months were as follows: pain-49 %, weakness-47.1 %, numbness-55.9 %, feeling tired-42.5 %. The majority of patients used the affected upper extremity for reaching without limitation, but a parts per thousand yen35 % reported limitation with household chores, carrying and lifting. Difficulty carrying and lifting could be predicted by BMI a parts per thousand yen 25 and use of the dominant affected upper limb. Different factors are associated with early versus later ROM loss. Symptoms reported by breast cancer survivors are frequently associated with functional limitations in upper extremity tasks and warrant intervention. Physical therapy using a prospective surveillance model of care may reduce severity of ROM loss, symptoms and functional upper extremity limitations 1 year after breast cancer surgery.

TI Alterations in in vivo knee joint kinematics following a femoral nerve branch block of the vastus medialis: Implications for patellofemoral pain syndrome SO CLINICAL BIOMECHANICS LA English DT Article DE MRI; Patella; Tibia; Femur; Correlation; Muscle; Function; Dynamic; Quadriceps ID LATERALIS MUSCLES; ELECTROMYOGRAPHIC ACTIVITY; TIBIOFEMORAL KINEMATICS; FUNCTIONAL-ACTIVITIES; COMPUTED-TOMOGRAPHY; PATELLAR TRACKING; WEIGHT-BEARING; ALIGNMENT; OBLIQUUS; MOTION AB Background: A potential source of patellofemoral pain, one of the most common problems of the knee, is believed to be altered patellofemoral kinematics due to a force imbalance around the knee. Although no definitive etiology for this imbalance has been found, a weak vastus medialis is considered a primary factor. Therefore, this study's purpose was to determine how the loss of vastus medialis obliquus force alters three-dimensional in vivo knee joint kinematics during a volitional extension task. Methods: Eighteen asymptomatic female subjects with no history of knee pain or pathology participated in this IRE approved study. Patellofemoral and tibiofemoral kinematics were derived from velocity data acquired using dynamic cine-phase contrast MRI. The same kinematics were then acquired immediately after administering a motor branch block to the vastus medialis obliquus using 3-5 ml of 1% lidocaine. A repeated measures analysis of variance was used to test the null hypothesis that the post- and pre-injection kinematics were no different. Findings: The null hypothesis was rejected for patellofemoral lateral shift (P=0.003, max change = 1.8 mm, standard deviation = 1.7 mm), tibiofemoral lateral shift (P<0.001, max change = 2.1 mm, standard deviation = 2.9 mm), and tibiofemoral external rotation (P<0.001, max change = 3.7 degrees, standard deviation = 4.4 degrees). Interpretation: The loss of vastus medialis obliquus function produced kinematic changes that mirrored the axial plane kinematics seen in individuals with patellofemoral pain, but could not account for the full extent of these changes. Thus, vastus medialis weakness is likely a major factor in, but not the sole source of, altered patellofemoral kinematics in such individuals. Published by Elsevier Ltd.

Using these artificial stimulation conditions, both naive as well as memory CD4+ T cells can be converted into induced Treg (iTreg) cells, but the cellular origin of such iTreg cells in vivo or in response to more physiologic stimulation with pathogen-derived antigens is less clear. Here, we demonstrate that a freeze/thaw lysate of Plasmodium falciparum schizont extract (PfSE) can induce functionally competent Treg cells from peripheral lymphocytes in a time- and dose-dependent manner without the addition of exogenous costimulatory factors. The PfSE-mediated induction of Treg cells required the presence of nTreg cells in the starting culture. Further experiments mixing either memory or naive T cells with antigen presenting cells and CFSE-labeled Treg cells identified CD4+CD45RO+CD25- memory T cells rather than Treg cells as the primary source of PfSE-induced Treg cells. Taken together, these data suggest that in the presence of nTreg cells, PfSE induces memory T cells to convert into iTreg cells that subsequently expand alongside PfSE-induced effector T cells.

TI Invariant natural killer T cells are not affected by lysosomal storage in patients with Niemann-Pick disease type C SO EUROPEAN JOURNAL OF IMMUNOLOGY LA English DT Article DE Antigen processing; presentation; CD1 molecules; NKT cell; Niemann-Pick type C disease ID NKT CELLS; ANTIGEN PRESENTATION; CD1D MOLECULES; TRAFFICKING; MICE; METABOLISM; MODULATION AB Invariant natural killer T (iNKT) cells are a specialised subset of T cells that are restricted to the MHC class I like molecule, CD1d. The ligands for iNKT cells are lipids, with the canonical superagonist being a-galactosylceramide, a non-mammalian glycosphingolipid. Trafficking of CD1d through the lysosome is required for the development of murine iNKT cells. Niemann-Pick type C (NPC) disease is a lysosomal storage disorder caused by dysfunction in either of two lysosomal proteins, NPC1 or NPC2, resulting in the storage of multiple lipids, including glycosphingolipids. In the NPC1 mouse model, iNKT cells are virtually undetectable, which is likely due to the inability of CD1d to be loaded with the selecting ligand due to defective lysosomal function and/or CD1d trafficking. However, in this study we have found that in NPC1 patients iNKT cells are present at normal frequencies, with no phenotypic or functional differences. In addi-tion, antigen-presenting cells derived from NPC1 patients are functionally competent to present several different CD1d/iNKT-cell ligands. This further supports the hypothesis that there are different trafficking requirements for the development of murine and human iNKT cells, and a functional lysosomal/late-endosomal compartment is not required for human iNKT-cell development.

TI Unique contribution of IRF-5-Ikaros axis to the B-cell IgG2a response SO GENES AND IMMUNITY LA English DT Article DE IRF-5; Ikaros; B cells; IgG isotype switching ID INTERFERON REGULATORY FACTOR; SYSTEMIC-LUPUS-ERYTHEMATOSUS; CLASS-SWITCH RECOMBINATION; DNA-BINDING PROTEINS; AUTOANTIBODY PRODUCTION; TRANSCRIPTION FACTORS; GENE INDUCTION; IRF FAMILY; T-CELLS; ACTIVATION AB IRF-5 is a transcription factor activated by toll like receptor (TLR)7 and TLR9 during innate immune responses. IRF-5 activates not only Type I IFN, but also inflammatory cytokines. Most importantly, a genetic variation in the IRF-5 gene shows a strong association with autoimmune diseases such as Lupus. Here, we report that IRF5-deficient mice have attenuated IgG2a/c responses to T-cell-dependent and -independent antigens and to polyoma virus infection. This defect is due to the intrinsic deletion of IRF-5 in B cells, as SCID mice reconstituted with Irf5 -/- B cells show a decrease in IgG2a/c expression after viral infection compared with mice that received wild-type B cells. Irf5 -/- B cells in vitro have diminished TLR and cytokine-induced class switching to IgG2a/c. Addressing the molecular mechanism, we show that IRF-5 regulates IgG2a/c expression by decreasing Ikaros expression; reconstitution of IRF-5 in Irf5 -/- B cells downregulates Ikaros levels and increases switching to IgG2a/c. The IRF site in ikzf1 promoter binds IRF-5, IRF-4 and IRF-8. We show that IRF-8 but not IRF-4 activates the ikzf1 promoter, and IRF-5 inhibits the transcriptional activity of IRF-8. Collectively, these results identify the IRF-5-Ikaros axis as a critical modulator of IgG2a/c class switching. C1 [Fang, C-M; Roy, S.; Nielsen, E.; Paul, M.; Pitha, P.

The aim of this study is to determine the relative expression of IL-21 in gingival tissues of chronic periodontitis patients and correlate/associate this expression with proinflammatory cytokines and clinical parameters of disease. Methods: Samples of gingival biopsies were collected from chronic periodontitis patients (n = 10) and controls (n = 8). The mRNA expressions of IL-21, IL-1 beta, IL-6, IL-17, IL-23, IL-10, and transforming growth factor-beta 1 (TGF-beta 1) were quantified using real-time reverse transcription-polymerase chain reaction. IL-21 levels were compared between chronic periodontitis and healthy gingival tissues and correlated with cytokine and clinical parameters of tissue destruction. Results: A significant overexpression of IL-21, IL-1 beta, IL-6, IL-17, and IL-23p19 was detected in periodontal disease affected tissues compared to healthy gingival tissues. IL-10 and TGF-beta 1 were, however, downregulated in periodontal lesions. IL-21 yielded significant positive correlations with probing depth, clinical attachment level, IL-18, and IL-6. In addition, IL-21 was negatively correlated with IL-10 and TGF-beta 1. Conclusions: IL-21 was overexpressed in chronic periodontitis gingival tissues and correlated with clinical parameters of periodontal destruction and with proinflammatory cytokines. Therefore, IL-21 might play a role in the tissue destruction that characterizes chronic periodontal disease. J Periodontol 2012;83:948-954.

Letord, Catherine Jaulent, Marie-Christine Griffon, Nicolas Thirion, Benoit Neveol, Aurelie TI Improving information retrieval using Medical Subject Headings Concepts: a test case on rare and chronic diseases SO JOURNAL OF THE MEDICAL LIBRARY ASSOCIATION LA English DT Article ID MESH AB Background: As more scientific work is published, it is important to improve access to the biomedical literature. Since 2000, when Medical Subject Headings (MeSH) Concepts were introduced, the MeSH Thesaurus has been concept based. Nevertheless, information retrieval is still performed at the MeSH Descriptor or Supplementary Concept level. Objective: The study assesses the benefit of using MeSH Concepts for indexing and information retrieval. Methods: Three sets of queries were built for thirty-two rare diseases and twenty-two chronic diseases: (1) using PubMed Automatic Term Mapping (ATM), (2) using Catalog and Index of French-language Health Internet (CISMeF) ATM, and (3) extrapolating the MEDLINE citations that should be indexed with a MeSH Concept. Results: Type 3 queries retrieve significantly fewer results than type 1 or type 2 queries (about 18,000 citations versus 200,000 for rare diseases; about 300,000 citations versus 2,000,000 for chronic diseases). CISMeF ATM also provides better precision than PubMed ATM for both disease categories. Discussion: Using MeSH Concept indexing instead of ATM is theoretically possible to improve retrieval performance with the current indexing policy. However, using MeSH Concept information retrieval and indexing rules would be a fundamentally better approach. These modifications have already been implemented in the CISMeF search engine.

Based on the modality used for imaging, the largest category of probes described in MICAD are those used for PET (41.6%), followed by agents used for single-photon emission computed tomography (30.3%), optical imaging (12.0%), MRI (9.3%), multimodality imaging (3.4%), ultrasound (2.4%) and x-ray/computed tomography (1.0%). This article is intended to be a guideline for new investigators and students who wish to characterize an optical imaging probe that will be used to perform in vivo molecular imaging studies. It is necessary, however, to ensure that these agents meet certain quality control parameters before they are used in various in vitro and in vivo applications.

TI Social after-effects of fur rubbing in tufted capuchin monkeys (Cebus apella): increased antagonism and reduced affiliation SO PRIMATES LA English DT Article DE Capuchin monkey; Fur rubbing; Group cohesion; Aggression; Affiliation; Olfactory communication ID CAPUCINUS; HYPOTHESES; BEHAVIOR; PLANTS AB Fur rubbing is widely believed to have a social bonding function in capuchin monkeys, yet a recent study of tufted capuchins revealed increased levels of aggression and reduced levels of affiliation after fur-rubbing bouts. This observed decrease in group cohesion may be attributable to increased intragroup competition for fur-rub material rather than being a direct effect of fur rubbing itself. To test this hypothesis, we separated individual tufted monkeys (Cebus apella) from their social group and provided them with fur-rub material or control material, thereby avoiding intragroup competition. After engagement with materials, we released subjects back into their social group and observed their subsequent interactions with group members. We found that subjects were more likely to encounter aggression and less likely to receive affiliation from others in the fur-rub condition than in the control condition. These results support the idea that fur rubbing carries social after-effects for capuchin monkeys. The precise mechanisms of the observed effects remain to be clarified in future studies.

The aim of this study was to investigate the role of extracellular FPP in platelet aggregation. Human platelets were studied with light transmission aggregometry, flow cytometry and [S-35]GTP gamma S binding assays. As shown previously, FPP could potentiate LPA-stimulated shape change. Surprisingly, FPP also acted as a selective insurmountable antagonist to ADP-induced platelet aggregation. FPP inhibited ADP-induced expression of P-selectin and the activated glycoprotein (Gp)IIb/IIIa receptor. FPP blocked ADP-induced inhibition of cAMP accumulation and [S-35)GTP gamma S binding in platelets. In Chinese hamster ovary cells expressing the P2Y(12) receptor, FPP caused a right-ward shift of the [S-35]GTP gamma S binding curve. In Sf9 insect cells expressing the human P2Y12 receptor, FPP showed a concentration-dependent, although incomplete inhibition of [H-3]PSB-0413 binding. Docking of FPP in a P2Y12 receptor model revealed molecular similarities with ADP and a good fit into the binding pocket for ADP. In conclusion, FPP is an insurmountable antagonist of ADP-induced platelet aggregation mediated by the P2Y12 receptor. It could be an endogenous antithrombotic factor modulating the strong platelet aggregatory effects of ADP in a manner similar to the use of clopidogrel, prasugrel or ticagrelor in the treatment of ischaemic heart disease.

They use PI4K to generate membranes enriched in phosphatidylinositide 4-phosphate (PtdIns4P or PI4P) lipids, which can be used as replication platforms. Viral replication machinery is assembled on these platforms as a supramolecular complex and PtdIns4P lipids regulate viral RNA synthesis. This article highlights these recent studies on the regulation of viral RNA synthesis by PtdIns4P lipids. It explores the potential mechanisms by which PtdIns4P lipids can contribute to viral replication and discusses the therapeutic potential of developing antiviral molecules that target host PI4Ks as a form of panviral therapy.

The ability to measure simultaneously multiple genes in the same cell is necessary to resolve the great diversity of cell subsets, as well as to define their function in the host. Fluorescence-based flow cytometry is the benchmark for this; with it, we can quantify 18 proteins per cell, at >10 000 cells/s. Mass cytometry is a new technology that promises to extend these capabilities significantly. Immunophenotyping by mass spectrometry provides the ability to measure >36 proteins at a rate of 1000 cells/s. We review these cytometric technologies, capable of high-content, high-throughput single-cell assays.

The goal of this study was to compare correlates of recovery based on a 3-year prospective design with those based on cross-sectional analyses of data from the same source. Methods Data from the 2001 to 2002 Wave 1 and 2004 to 2005 Wave 2 National Epidemiologic Survey on Alcohol and Related Conditions (NESARC) were used to examine baseline characteristics associated with Wave 2 recovery from alcohol dependence, among those who classified with past-year DSM-IV alcohol dependence at Wave 1 (n = 1,172). Results Abstinent recovery was significantly associated with Black/Asian/Hispanic race/ethnicity, children <1 year of age in the household at baseline, attending religious services greater than or equal to weekly at follow-up, and having initiated help-seeking that comprised/included 12-step participation within <3 years prior to baseline. Nonabstinent recovery was positively associated with being never married at baseline, having job problems or being unemployed in the year preceding baseline, attending religious services less than weekly at follow-up, baseline smoking and volume of ethanol intake, and having terminated a first marriage within <3 years prior to baseline. Findings, including others of marginal significance (0.05 < p < 0.10), generally supported results from prior pseudo-prospective survival analyses with time-dependent covariates but differed in many ways from cross-sectional analyses of Wave 1 NESARC data. Conclusions Various aspects of study design must be considered when interpreting correlates of recovery. Cross-sectional analyses of lifetime correlates of recovery are highly subject to misinterpretation, but pseudo-prospective survival analyses with time-dependent covariates may yield results as valid as those from prospective studies.

As public and private funding agencies around the world enhance and expand their support of Alzheimer's disease research, there is an urgent need to coordinate funding strategies and leverage resources to maximize the impact on public health and avoid duplication of effort and inefficiency. Such coordination requires a comprehensive assessment of the current landscape of Alzheimer's disease research in the United States and internationally. To this end, the National Institute on Aging at the National Institutes of Health and the Alzheimer's Association developed the Common Alzheimer's Disease Research Ontology (CADRO) as a dynamic portfolio analysis tool that can be used by funding agencies worldwide for strategic planning and coordination.

Hydrogen-1 MR spectroscopy (H-1-MRS) is gaining acceptance as a non-invasive technique for assessment of hepatic steatosis, and the findings have been found to correlate closely with histopathologic grade. The aims of this study were to validate H-1-MRS performed with a 3-T MRI system for quantifying hepatic steatosis and to determine threshold values of H-1-MRS proton density fat fraction corresponding to standard histopathologic grade in patients undergoing diagnostic liver biopsy. SUBJECTS AND METHODS. We conducted a prospective cross-sectional liver MRS study with 52 subjects undergoing diagnostic liver biopsy. The diagnostic accuracy of H-1-MRS was evaluated with receiver operating characteristic curves. RESULTS. The diagnostic accuracy of H-1-MRS for hepatic steatosis was high with an area under the receiver operating characteristic curve of 0.94 (95% CI, 0.88-1.0). Results were similar for three H-1-MRS measurements obtained at different locations in the liver, for two independent pathologists, and whether fibrosis was present or absent. One third of participants had elevated transaminase concentrations of unknown cause, and H-1-MRS estimates of steatosis had perfect agreement with histopathologic grade in this group. Calculated H-1-MRS proton density fat fraction thresholds for histologic grades were less than 17% for grade 0 or trace steatosis, 17-38.6% for grade 1, and greater than 38.6% for grade 2 or higher. CONCLUSION. Hydrogen-1 MR spectroscopy is an effective, noninvasive technique that can be used to diagnose and quantify hepatic steatosis. Hydrogen-1 MR spectroscopy thresholds corresponded with histopathologic grades and may be useful in the workup of patients with elevated transaminase concentrations.

The purpose of this article is to determine whether there is an association between visceral adiposity measured on CT colonography (CTC) and colorectal polyps. MATERIALS AND METHODS. Patients who underwent CTC and same-day optical colonoscopy (n = 1186) were analyzed. Visceral adipose tissue volumes and volume percentages relative to total internal body volume were measured on slices in the L2-L3 regions on supine CTC scans with validated fully automated software. Student t test, odds ratio, logistic regression, and receiver operating characteristic analyses were performed. RESULTS. For subjects with (n = 345) and without (n = 841) adenomatous polyps, the mean (+/- SD) volume percentages were 31.2% +/- 10.8% and 28.2% +/- 11.3%, respectively (p < 0.0001). For subjects with (n = 244) and without (n = 942) hyperplastic polyps, the volume percentages were 31.8% +/- 10.7% and 28.3% +/- 11.2%, respectively (p < 0.0001). Comparing the lowest and highest quintiles of volume percentage, the odds ratios for having at least one adenomatous polyp or hyperplastic polyp versus no polyp were 2.06 (95% CI, 1.36-3.13) and 1.71 (95% CI, 1.08-2.71), and the prevalence of having adenomatous polyps or hyperplastic polyps increased by 14% and 8%, respectively. CONCLUSION. Subjects with higher visceral adiposity measurements on CTC have a greater risk for the presence of colonic polyps.

Methods: Thirty-seven patients from 31 families were enrolled who met the clinical criteria for BBS and for whom a BBS mutation had been identified. Seventeen patients harbored mutations in BBS1, 10 in BBS10, and 10 in other genes (BBS2, BBS3, BBS5, BBS7, and BBS12). All the patients underwent ocular examination; 36 patients had computerized full-field electroretinograms (ERGs). Results: Visual acuity was significantly better in BBS1 patients than in patients with other BBS mutations (P=.01), and a larger proportion of BBS1 patients had good (>= 20/50) visual acuity (P=.01). The ERG amplitudes were significantly higher in BBS1 patients than in patients with other BBS mutations in response to 0.5-Hz and 30-Hz flashes (P <.001 for both). All the BBS1 patients harbored at least 1 missense mutation compared with only 45% of patients with mutations in other BBS genes (P <.001); the rest harbored only null alleles. However, multivariate analysis demonstrated that visual acuity or ERG amplitude did not depend on the type of mutation present (missense or null) when controlling for BBS gene. Prevalences of bone spicule pigmentation and cataract were comparable in BBS subtypes. Conclusions: Patients with BBS1 mutations had a milder phenotype than did patients with mutations in other BBS genes. Clinically, this manifested as significantly better visual acuity and larger ERG amplitudes.

The long treatment duration has led to increased patient noncompliance with therapy. This, in turn, drives the development of additional drug resistance In a spiral that has resulted in some forms of TB being currently untreatable by existing drugs. New antitubercular drugs in development, particularly those with mechanisms of action that are different from existing first- and second-line TB drugs, are anticipated to be effective against both drug-sensitive and drug-resistant TB. SQ109 is a new TB drug candidate with a novel mechanism of action that was safe and well tolerated in Phase I and early Phase II clinical trials.

The literature consists mainly of isolated case reports. Patients: We studied 12 cases (eight males and four females) diagnosed between 1986 and 2010 with CS and thymic NET who underwent surgical resection. Main Outcome Measures: We measured time from onset of CS to diagnosis of thymic NET, tumor size, histological grade, time to recurrence, and survival and performed a meta-analysis of other published cases of CS associated with thymic NET. Results: Eleven of 12 patients presented with classic features of CS at a median age of 21 yr (range, 7-51). Four were children. The 24-h urine free cortisol was greater than 16-fold of normal, and biochemical testing was consistent with ectopic ACTH production in all 11. Another patient presenting with pulmonary embolus had a thymic mass and was later diagnosed with CS. All patients underwent thymectomy, and nine of 10 tumors exhibited positive ACTH immunochemistry. Median tumor diameter was 5 cm (range, 1-11.5). Six patients recurred 20-28 months after surgery with metastases to mediastinal lymph nodes (n = 5), bone (n = 5), liver (n = 1), parotid gland (n = 1), and breast (n = 1). Four of five patients treated with radiation therapy also received chemotherapy. All recurrent patients received ketoconazole; four later underwent bilateral adrenalectomy. Six recurrent patients died 22-90 months(median, 57) after thymectomy. At last review, six patients were alive 14-90 months (median, 49) after thymectomy. These data are similar to those from the meta-analysis. Conclusions: Thymic ACTH-producing NET is an aggressive disease that should be considered in CS with ectopic ACTH secretion, particularly in younger patients.

TI Somatic GNAS Mutation Causes Widespread and Diffuse Pituitary Disease in Acromegalic Patients with McCune-Albright Syndrome SO JOURNAL OF CLINICAL ENDOCRINOLOGY & METABOLISM LA English DT Article ID GROWTH-HORMONE EXCESS; STIMULATORY G-PROTEIN; FIBROUS DYSPLASIA; PRECOCIOUS PUBERTY; ALPHA-SUBUNIT; GENE; PIGMENTATION; HYPERPLASIA; GIGANTISM; TUMORS AB Context: McCune-Albright syndrome (MAS) is caused by sporadic mutations of the GNAS. Patients exhibit features of acromegaly. In most patients, GH-secreting pituitary adenomas have been held responsible for this presentation. However, surgical adenomectomy rarely eliminates excess GH production. Objective: The aim of this study was to elucidate pituitary pathology in patients with MAS and to explain the basis of failure of adenomectomy to eliminate GH hypersecretion. Design and Setting: We conducted a case series at the National Institutes of Health. Intervention(s): Interventions included medical therapy and transsphenoidal surgery. Patients and Main Outcome Measures: We studied clinical and imaging features and the histology and molecular features of the pituitary of four acromegalic MAS patients. Results: We identified widespread and diffuse pituitary gland disease. The primary pathological changes were characterized by hyperplastic and neoplastic change, associated with overrepresentation of somatotroph cells in structurally intact tissue areas. Genetic analysis of multiple microdissected samples of any type of histological area consistently revealed identical GNAS mutations in individual patients. The only patient with remission after surgery received complete hypophysectomy in addition to removal of multiple GH-secreting tumors. Conclusions: These findings indicate developmental effects of GNAS mutation on the entire anterior pituitary gland. The pituitary of individual cases contains a spectrum of changes with regions of normal appearing gland, hyperplasia, and areas of fully developed adenoma formation, as well as transitional stages between these entities. The primary change underlying acromegaly in MAS patients is somatotroph hyperplasia involving the entire pituitary gland, with or without development of somatotroph adenoma. Thus, successful clinical management, whether it is medical, surgical, or via irradiation, must target the entire pituitary, not just the adenomas evident on imaging.

TI Metabolic Slowing with Massive Weight Loss despite Preservation of Fat-Free Mass SO JOURNAL OF CLINICAL ENDOCRINOLOGY & METABOLISM LA English DT Article ID RESTING ENERGY-EXPENDITURE; LONG-TERM PERSISTENCE; BODY-WEIGHT; ADAPTIVE THERMOGENESIS; EXERCISE; RESISTANCE; OBESITY; HUMANS; RESTRICTION; INDIVIDUALS AB Context: An important goal during weight loss is to maximize fat loss while preserving metabolically active fat-free mass (FFM). Massive weight loss typically results in substantial loss of FFM potentially slowing metabolic rate. Objective: Our objective was to determine whether a weight loss program consisting of diet restriction and vigorous exercise helped to preserve FFM and maintain resting metabolic rate (RMR). Participants and Intervention: We measured body composition by dual-energy x-ray absorptiometry, RMR by indirect calorimetry, and total energy expenditure by doubly labeled water at baseline (n = 16), wk 6 (n = 11), and wk 30 (n = 16). Results: At baseline, participants were severely obese (X +/- D; body mass index 49.4 +/- 9.4 kg/m(2)) with 49 +/- 5% body fat. At wk 30, more than one third of initial body weight was lost (-38 +/- 9%) and consisted of 17 +/- 8% from FFM and 83 +/- 8% from fat. RMR declined out of proportion to the decrease in body mass, demonstrating a substantial metabolic adaptation (-244 +/- 231 and -504 +/- 171 kcal/d at wk 6 and 30, respectively, P < 0.01). Energy expenditure attributed to physical activity increased by 10.2 +/- 5.1 kcal/kg.d at wk 6 and 6.0 +/- 4.1 kcal/kg.d at wk 30 (P < 0.001 vs. zero). Conclusions: Despite relative preservation of FFM, exercise did not prevent dramatic slowing of resting metabolism out of proportion to weight loss. This metabolic adaptation may persist during weight maintenance and predispose to weight regain unless high levels of physical activity or caloric restriction are maintained.

TI First-Degree Relatives of Type 2 Diabetic Patients Have Reduced Expression of Genes Involved in Fatty Acid Metabolism in Skeletal Muscle SO JOURNAL OF CLINICAL ENDOCRINOLOGY & METABOLISM LA English DT Article ID INSULIN-RESISTANCE; MELLITUS; GLUCOSE; OXIDATION; PHOSPHORYLATION; PANCREAS; HUMANS AB Context: First-degree relatives of patients with type 2 diabetes (FH+) have been shown to have decreased energy expenditure and decreased expression of mitochondrial genes in skeletal muscle. In previous studies, it has been difficult to distinguish whether mitochondrial dysfunction and differential regulation of genes are primary (genetic) or due to reduced physical activity, obesity, or other correlated factors. Objective: The aim of this study was to investigate whether mitochondrial dysfunction is a primary defect or results from an altered metabolic state. Design: We compared gene expression in skeletal muscle from 24 male subjects with FH and 26 without FH matched for age, glucose tolerance, VO2peak (peak oxygen uptake), and body mass index using microarrays. Additionally, type fiber composition, mitochondrial DNA content, and citrate synthase activity were measured. The results were followed up in an additional cohort with measurements of in vivo metabolism. Results: FH+ vs. FH- subjects showed reduced expression of mitochondrial genes (P = 2.75 x 10(-6)), particularly genes involved in fatty acid metabolism (P = 4.08 x 10(-7)), despite similar mitochondrial DNA content. Strikingly, a 70% reduced expression of the monoamine oxidase A(MAOA) gene was found in FH+ vs. FH- individuals (P = 0.0009). Down-regulation of the genes involved in fat metabolism was associated with decreased in vivo fat oxidation and increased glucose oxidation examined in an additional cohort of elderly men. Conclusions: These results suggest that genetically altered fatty acid metabolism predisposes to type 2 diabetes and propose a role for catecholamine-metabolizing enzymes like MAOA in the regulation of energy metabolism.

In renal failure, secondary hyperparathyroidism (sHPT) occurs with multiple tumor development as a result of calcium and vitamin D regulatory disturbance. Objective: The aim of the study was to investigate whether HIC1 may act as a tumor suppressor in the parathyroid glands and whether deregulated expression involves epigenetic mechanisms. Patients and Methods: Parathyroid tumors from patients with pHPT included single adenomas, multiple tumors from the same patient, and cancer. Hyperplastic parathyroid glands from patients with sHPT and hypercalcemia and normal parathyroid tissue specimens were included in the study. Quantitative RT-PCR, bisulfite pyrosequencing, colony formation assay, chromatin immunoprecipitation, and RNA interference was used. Results: HIC1 was generally underexpressed regardless of the hyperparathyroid disease state including multiple parathyroid tumors from the same patient, and overexpression of HIC1 led to a decrease in clonogenic survival of parathyroid tumor cells. Only the carcinomas showed a high methylation level and reduced HIC1 expression. Cell culture experiments, including use of primary parathyroid tumor cells prepared directly after operation, the general histone methyltransferase inhibitor 3-deazaneplanocin A, chromatin immunoprecipitation, and RNA interference of DNA methyltransferases and EZH2 (enhancer of zeste homolog 2), supported a role of repressive histone H3 modifications (H3K27me2/3) rather than DNA methylation in repression of HIC1. Conclusions: The results strongly support a growth-regulatory role of HIC1 in the parathyroid glands and suggest that perturbed expression of HIC1 may represent an early event during tumor development. Repressive histone modification H3K27me2/3 is involved in repression of HIC1 expression in hyperparathyroid tumors.

The matrix-assisted laser desorption/ionization-TOF/TOF-MS/MS analyses of the tryptic digests of the glycoconjugates having a hapten:BSA ratio of 4.3:1, 6.6:1 and 13.2:1 revealed only three glycation sites, on the following lysine residues: Lys 235, Lys 437 and Lys 455. Digestion of the neoglycoconjugates with the proteases trypsin and GluC V8 gave complementary structural information and was shown to maximize the number of recognized glycation sites. Here, we report identification of 20, 27 and 33 glycation sites using LC-ESI-QqTOF-MS/MS analysis of a series of synthetic neoglycoconjugates with a hapten:BSA ratio of, respectively, 4.3:1, 6.6:1 and 13.2:1. We also tentatively propose that all the glycated lysine residues are located mainly near the outer surface of the protein. Copyright (C) 2012 John Wiley & Sons, Ltd.

TI Cross-Correlation Map Analyses Show Weather Variation Influences on Mosquito Abundance Patterns in Saginaw County, Michigan, 1989-2005 SO JOURNAL OF MEDICAL ENTOMOLOGY LA English DT Article DE West Nile virus; Aedes vexans; Culex pipiens; Culex restuans; cross-correlation map ID WEST-NILE-VIRUS; CULEX-RESTUANS DIPTERA; AEDES-VEXANS DIPTERA; VECTOR COMPETENCE; PIPIENS DIPTERA; CLIMATE-CHANGE; CULICIDAE; IMPACT; SURVEILLANCE; CONNECTICUT AB Weather is important determinant of mosquito abundance that, in turn, influences vectorborne disease dynamics. In temperate regions, transmission generally is seasonal as mosquito abundance and behavior varies with temperature, precipitation, and other meteorological factors. We investigated how such factors affected species-specific mosquito abundance patterns in Saginaw County, MI, during a 17-yr period. Systematic sampling was undertaken at 22 trapping sites from May to September, during 1989-2005, for 19,228 trap-nights and 300,770 mosquitoes in total. Aedes vexans (Meigen), Culex pipiens L. and Culex restuans Theobald, the most abundant species, were analyzed. Weather data included local daily maximum temperature, minimum temperature, total precipitation, and average relative humidity. In addition to standard statistical methods, cross-correlation mapping was used to evaluate temporal associations with various lag periods between weather variables and species-specific mosquito abundances. Overall, the average number of mosquitoes was 4.90 per trap-night for Ae. vexans, 2.12 for Cx. pipiens, and 1.23 for Cx. restuans. Statistical analysis of the considerable temporal variability in species-specific abundances indicated that precipitation and relative humidity 1 wk prior were significantly positively associated with Ae. vexans, whereas elevated maximum temperature had a negative effect during summer. Cx. pipiens abundance was positively influenced by the preceding minimum temperature in the early season but negatively associated with precipitation during summer and with maximum temperature in July and August. Cx. restuans showed the least weather association, with only relative humidity 2-24 d prior being linked positively during late spring-early summer. The recently developed analytical method applied in this study could enhance our understanding of the influences of weather variability on mosquito population dynamics.

TI A founder mutation in Vps37A causes autosomal recessive complex hereditary spastic paraparesis SO JOURNAL OF MEDICAL GENETICS LA English DT Article ID ESCRT-I; PROTEIN SPARTIN; TROYER-SYNDROME; PARAPLEGIA; MEMBRANE; GENE; ATLASTIN; CYTOKINESIS; TRAFFICKING; ZEBRAFISH AB Background Members of two seemingly unrelated kindreds of Arab Moslem origin presented with pronounced early onset spastic paraparesis of upper and lower limbs, mild intellectual disability, kyphosis, pectus carinatum and hypertrichosis. Methods The authors performed neurological and developmental examinations on the affected individuals. The authors conducted whole genome linkage and haplotype analyses, followed by sequencing of candidate genes; RNA and protein expression studies; and finally proof of principle investigations on knockdown morpholino oligonucleotide injected zebrafish. Results The authors characterise a novel form of autosomal recessive complex hereditary spastic paraparesis (CHSP). MRI studies of brain and spinal cord were normal. Within a single significantly linked locus the authors ultimately identified a homozygous missense mutation c.1146A>T (p.K382N) in the vacuolar protein sorting 37A (Vps37A) gene, fully penetrant and segregating with the disease in both families. Mobility was significantly reduced in Vps37A knockdown morpholino oligonucleotide injected zebrafish, supporting the causal relationship between mutations in this gene and the phenotype described in the patients of this study. Conclusions The authors provide evidence for the involvement of Vps37A, a member of the endosomal sorting complex required for transport (ESCRT) system, in upper motor neuron disease. The ESCRT system has been shown to play a central role in intracellular trafficking, in the maturation of multivesicular bodies and the sorting of ubiquitinated membrane proteins into internal luminal vesicles.

Roessler, Erich Muenke, Maximilian TI Genotypic and phenotypic analysis of 396 individuals with mutations in Sonic Hedgehog SO JOURNAL OF MEDICAL GENETICS LA English DT Article ID HOLOPROSENCEPHALY-LIKE PHENOTYPE; GENE; ZIC2; FREQUENCY; SPECTRUM; FAMILY; SIX3; SHH AB Background Holoprosencephaly (HPE), the most common malformation of the human forebrain, may result from mutations in over 12 genes. Sonic Hedgehog (SHH) was the first such gene discovered; mutations in SHH remain the most common cause of nonchromosomal HPE. The severity spectrum is wide, ranging from incompatibility with extrauterine life to isolated midline facial differences. Objective To characterise genetic and clinical findings in individuals with SHH mutations. Methods Through the National Institutes of Health and collaborating centres, DNA from approximately 2000 individuals with HPE spectrum disorders were analysed for SHH variations. Clinical details were examined and combined with published cases. Results This study describes 396 individuals, representing 157 unrelated kindreds, with SHH mutations; 141 (36%) have not been previously reported. SHH mutations more commonly resulted in non-HPE (64%) than frank HPE (36%), and non-HPE was significantly more common in patients with SHH than in those with mutations in the other common HPE related genes (p<0.0001 compared to ZIC2 or SIX3). Individuals with truncating mutations were significantly more likely to have frank HPE than those with non-truncating mutations (49% vs 35%, respectively; p=0.012). While mutations were significantly more common in the N-terminus than in the C-terminus (including accounting for the relative size of the coding regions, p=0.00010), no specific genotype. phenotype correlations could be established regarding mutation location. Conclusions SHH mutations overall result in milder disease than mutations in other common HPE related genes. HPE is more frequent in individuals with truncating mutations, but clinical predictions at the individual level remain elusive.

Instances of wasting or poor weight gain may precede linear growth retardation. We analyzed longitudinal anthropometric data for 1599 children from 8 cohort studies to determine the effect of wasting [weight-for-length Z-score (WLZ) < -2] and variability in WLZ in the first 17 moon length-for-age Z-score (LAZ) at 18-24 mo of age. In addition, we considered the effects of change in WLZ during the previous 6-mo period on length at 18 and 24 mo. Wasting at 6-11 or 12-17 mo was associated with decreased LAZ; however, children who experienced wasting only at 0-5 mo did not suffer any long-term growth deficits compared with children with no wasting during any period. Children with greater WLZ variability (>= 0.5 SD) in the first 17 mo of life were shorter [LAZ = -0.51 SD (95% Cl: -0.67, -0.36 SD)] at 18-24 mo of age than children with WLZ variability <0.5. Change in WLZ in the previous 6-rno period was directly associated with greater attained length at 18 mo [0.33 cm (95% Cl: 0.11, 0.54 cm)] and 24 mo [0.72 cm (95% Cl: 0.52, 0.92 cm)]. Children with wasting, highly variable WLZ, or negative changes in WLZ are at a higher risk For linear growth retardation, although instances of wasting may not be the primary cause of stunting in developing countries.

Adaptations to nutrient supply are executed through tuning of multiple protein networks that include transcription factors, histones, modifying enzymes, translation factors, membrane and nuclear receptors, and secreted proteins. However, the simultaneous quantitative and qualitative measurement of all proteins that regulate cancer processes is not practical using traditional protein methodologies. Proteomics offers an attractive opportunity to fill this knowledge gap and unravel the effects of dietary components on protein networks that impinge on cancer. The articles presented in this supplement are from talks proffered in the "Nutrition Proteomics and Cancer Prevention" session at the American Institute for Cancer Research Annual Research Conference on Food, Nutrition, Physical Activity and Cancer held in Washington, DC on October 21 and 22, 2010. Recent advances in MS technologies suggest that studies in nutrition and cancer prevention may benefit from the adoption of proteomic tools to elucidate the impact on biological processes that govern the transition from normal to malignant phenotype; to identify protein changes that determine both positive and negative responses to food components; to assess how protein networks mediate dose-, time-, and tissue-dependent responses to food components; and, finally, for predicting responders and nonresponders. However, both the limited accessibility to proteomic technologies and research funding appear to be hampering the routine adoption of proteomic tools in nutrition and cancer prevention research. J.

Studies have reported that ITC binding to intracellular proteins may be an important event for initiating apoptosis. Specific protein target(s) and molecular mechanisms for ITC have been investigated in human lung cancer A549 cells using proteomic tools. Cells were treated with various amounts (1-100 mu mol/L) of radiolabeled phenethyl-ITC (PEITC) and sulforaphane (SFN) and the extracted proteins resolved using 2-dimensional gel electrophoresis. The results of mass spectrometric analyses suggested that tubulin may be an in vivo binding target for ITC. The binding of ITC to tubulin was associated with growth arrest. The proliferation of A549 cells was significantly reduced by ITC, with benzyl-ITC (BITC) having a greater relative activity than PEITC or SFN. Mitotic arrest and apoptosis as well as disruption of microtubule polymerization were induced in the order: BITC > PEITC > SFN. An analysis of tubulins isolated from BITC-treated A549 cells showed that Cys(347), a conserved cysteine in all alpha-tubulin isoforms, was covalently modified by BITC. Taken together, these results suggest that tubulin is a binding target of ITC and that this interaction can lead to growth inhibition and apoptosis. J. Nutr. 142: 1377S-1381S, 2012.

We focused on six categories of applications in radiology: medical image segmentation, registration, computer aided detection and diagnosis, brain function or activity analysis and neurological disease diagnosis from fMR images, content-based image retrieval systems for CT or MRI images, and text analysis of radiology reports using natural language processing (NLP) and natural language understanding (NLU). This survey shows that machine learning plays a key role in many radiology applications. Machine learning identifies complex patterns automatically and helps radiologists make intelligent decisions on radiology data such as conventional radiographs, CT, MRI, and PET images and radiology reports. In many applications, the performance of machine learning-based automatic detection and diagnosis systems has shown to be comparable to that of a well-trained and experienced radiologist. Technology development in machine learning and radiology will benefit from each other in the long run. Key contributions and common characteristics of machine learning techniques in radiology are discussed. We also discuss the problem of translating machine learning applications to the radiology clinical setting, including advantages and potential barriers. (c) 2012 Published by Elsevier B.V.

TI Automatic motion compensation of free breathing acquired myocardial perfusion data by using independent component analysis SO MEDICAL IMAGE ANALYSIS LA English DT Article DE Perfusion; Heart; Registration; Independent component analysis; Motion compensation ID MR IMAGE SEQUENCES; NONRIGID REGISTRATION; MUTUAL INFORMATION; DEFORMATION AB Images acquired during free breathing using first-pass gadolinium-enhanced myocardial perfusion magnetic resonance imaging (MRI) exhibit a quasiperiodic motion pattern that needs to be compensated for if a further automatic analysis of the perfusion is to be executed. In this work, we present a method to compensate this movement by combining independent component analysis (ICA) and image registration: First, we use ICA and a time-frequency analysis to identify the motion and separate it from the intensity change induced by the contrast agent. Then, synthetic reference images are created by recombining all the independent components but the one related to the motion. Therefore, the resulting image series does not exhibit motion and its images have intensities similar to those of their original counterparts. Motion compensation is then achieved by using a multi-pass image registration procedure. We tested our method on 39 image series acquired from 13 patients, covering the basal, mid and apical areas of the left heart ventricle and consisting of 58 perfusion images each. We validated our method by comparing manually tracked intensity profiles of the myocardial sections to automatically generated ones before and after registration of 13 patient data sets (39 distinct slices). We compared linear, non-linear, and combined ICA based registration approaches and previously published motion compensation schemes. Considering run-time and accuracy, a two-step ICA based motion compensation scheme that first optimizes a translation and then for non-linear transformation performed best and achieves registration of the whole series in 32 +/- 12 s on a recent workstation. The proposed scheme improves the Pearsons correlation coefficient between manually and automatically obtained time-intensity curves from.84. +/- 19 before registration to.96 +/- .06 after registration.

It is an essential activator for glucocerebrosidase, the enzyme deficient in Gaucher disease. Gaucher disease is a rare autosomal recessive lysosomal storage disorder caused by mutations in the GBA gene that exhibits vast phenotypic heterogeneity, despite its designation as a "simple" Mendelian disorder. The observed phenotypic variability has led to a search for disease modifiers that can alter the Gaucher phenotype. The PSAP gene encoding saposin C is a prime candidate modifier for Gaucher disease. In humans, saposin C deficiency due to mutations in PSAP results in a Gaucher-like phenotype, despite normal in vitro glucocerebrosidase activity. Saposin C deficiency has also been shown to modify phenotype in one mouse model of Gaudier disease. The role of saposin C as an activator required for normal glucocerebrosidase function, and the consequences of saposin C deficiency are described, and are being explored as potential modifying factors in patients with Gaucher disease.

Here we utilize a single, yet multifunctional, hyaluronic acid-based biosurfactant to simultaneously disperse nanocarbons and target single-walled carbon nanotubes (SWCNTs) to CD44 receptor positive tumor cells with prompt uptake. Cellular uptake was monitored by intracellular enzyme-activated fluorescence, and localization of SWCNTs within cells was further confirmed by Raman mapping. In vivo photoacoustic, fluorescence, and positron emission tomography imaging of coated SWCNTs display high tumor targeting capability while providing long-term, fluorescence molecular imaging of targeted enzyme events. By utilizing a single biomaterial surfactant for SWCNT dispersion without additional bioconjugation, we designed a facile technique that brings nanocarbons closer to their biomedical potential.

Likewise, through serial transplantations, no loss of potency is detected when compared to similar transplantations of the youngest mammary tissue tested. This demonstrates that stem cell activity is maintained intact throughout the lifetime of the animal despite aging and the repeated expansion and depletion of the mammary epithelium through multiple rounds of pregnancy, lactation and involution. These facts support the contention that mammary stem cells reside in protected tissue locales (niches), where their reproductive potency remains essentially unchanged through life. Disruption of the tissue, to produce dispersed cells results in the desecration of the protection afforded by the "niche" and leads to a reduced capacity of dispersed epithelial cells (in terms of the number transplanted) to recapitulate complete functional mammary structures. Our studies demonstrate that during the reformation of mammary stem cell niches by dispersed epithelial cells in the context of the intact epithelium-free mammary stroma, non-mammary cells, including mouse and human cancer cells, may be sequestered and reprogrammed to perform mammary epithelial cell functions including those ascribed to mammary stem/progenitor cells.

Several striking new empirical results in this area are perplexing within the standard conceptual framework of biomedicine, and this highlights the need for new perspectives from ecology and from dynamical systems theory. Here, we discuss recent results concerning sources of individual variation, temporal variation within individuals, long-term changes after transient perturbations and individualized responses to perturbation within the human gut microbiome.

Here, we describe a series of aryl substituted alkynyl analogues of the prototypic mGluR5 NAM 2-methyl-6-(phenylethynyl)pyridine (MPEP, 1). Displacement of [H-3]1 binding in rat brain membranes showed that several of these novel compounds displayed high affinity binding (K-i < 10 nM) for mGluR5, with up to a 24 fold increase in affinity over 1. Replacements of the 2-position Me on the pyridyl ring of 1 along with various 3'-CN, 5'-substitutions were generally well tolerated All of the active analogues in this series had cLog P values in the 2-5 range and displayed inverse agonist characteristics in an ELISA-based assay of G(q)alpha-mediated IP3 production. Compounds 7i and 7j produced in vivo effects in mouse models of anxiety-like behaviors more potently than 1 or 3-3-((2-methyl-4-thiazolyl)ethynyl)pyridine (MTEP, 2), supporting their utility as in vivo tools.

Similar 4'-truncated C2-arylethynyl-(N)-methanocarba nucleosides containing alkyl or alkylaryl groups at the N-6 position were low-efficacy agonists or antagonists of the human A(3)AR with high selectivity. Higher hA(3)AR affinity was associated with N-6-methyl and ethyl (K-i = 3-6 nM) than with N-6-arylallcyl groups. However, combined C2-phenylethynyl and N-6-2-phenylethyl substitutions in selective antagonist 15 provided a K-i of 20 nM. Differences between 4'-truncated and nontruncated analogues of extended C2-p-biphenylethynyl substitution suggested a ligand reorientation in AR binding, dominated by bulky N-6 groups in analogues lacking a stabilizing S'-uronamide moiety. Thus, 4'-truncation of C2-arylethynyl-(N)-methanocarba adenosine derivatives is compatible with general preservation of A(3)AR selectivity, especially with small N-6 groups, but reduced efficacy in A(3)AR-induced inhibition of adenylate cyclase.

We analyzed data from 12 case-control studies within the International Pancreatic Cancer Case-Control Consortium (PanC4), including 6507 pancreatic cases and 12 890 controls. We estimated summary odds ratios (ORs) by pooling study-specific ORs using random-effects models. Compared with never smokers, the OR was 1.2 (95% confidence interval [CI] 1.0-1.3) for former smokers and 2.2 (95% CI 1.7-2.8) for current cigarette smokers, with a significant increasing trend in risk with increasing number of cigarettes among current smokers (OR = 3.4 for >= 35 cigarettes per day, P for trend < 0.0001). Risk increased in relation to duration of cigarette smoking up to 40 years of smoking (OR = 2.4). No trend in risk was observed for age at starting cigarette smoking, whereas risk decreased with increasing time since cigarette cessation, the OR being 0.98 after 20 years. This uniquely large pooled analysis confirms that current cigarette smoking is associated with a twofold increased risk of pancreatic cancer and that the risk increases with the number of cigarettes smoked and duration of smoking. Risk of pancreatic cancer reaches the level of never smokers similar to 20 years after quitting.

TI Body mass, tobacco smoking, alcohol drinking and risk of cancer of the small intestine-a pooled analysis of over 500 000 subjects in the Asia Cohort Consortium SO ANNALS OF ONCOLOGY LA English DT Article DE alcohol drinking; body mass index; prospective studies; small intestine cancer; tobacco smoking ID CIGARETTE-SMOKING; CROHNS-DISEASE; ADENOCARCINOMA; EPIDEMIOLOGY; POPULATION; METAANALYSIS; ASSOCIATION; OBESITY; INDEX AB The evidence for a role of tobacco smoking, alcohol drinking, and body mass index (BMI) in the etiology of small intestine cancer is based mainly on case-control studies from Europe and United States. We harmonized the data across 12 cohort studies from mainland China, Japan, Korea, Singapore, and Taiwan, comprising over 500 000 subjects followed for an average of 10.6 years. We calculated hazard ratios (HRs) for BMI and (only among men) tobacco smoking and alcohol drinking. A total of 134 incident cases were observed (49 adenocarcinoma, 11 carcinoid, 46 other histologic types, and 28 of unknown histology). There was a statistically non-significant trend toward increased HR in subjects with high BMI [HR for BMI > 27.5 kg/m(2), compared with 22.6-25.0, 1.50; 95% confidence interval (CI) 0.76-2.96]. No association was suggested for tobacco smoking; men drinking > 400 g of ethanol per week had an HR of 1.57 (95% CI 0.66-3.70), compared with abstainers. Our study supports the hypothesis that elevated BMI may be a risk factor for small intestine cancer. An etiologic role of alcohol drinking was suggested. Our results reinforce the existing evidence that the epidemiology of small intestine cancer resembles that of colorectal cancer.

Although the indication has historically been mostly palliative, response rates in skeletal-related events (SRE) remain low. Denosumab has been shown to be effective in prolonging time to first SRE in clinical settings, however, critical questions remain on its ability to affect bone metastases in mCRPC. The landscape for research progress in reducing SREs using novel pharmacotherapies is growing rapidly, with several agents in clinical trials. This focused review outlines the most promising investigational drugs for treating bone metastases in mCRPC. C1 [Figg, William D.] NCI, Med Oncol Branch, Ctr Canc Res, NIH, Bethesda, MD 20892 USA.

However, radiation-induced tumor cell death is limited by a number of factors, including the adverse response of the tumor microenvironment to radiation treatment and tumor-acquired mechanisms of evasive resistance. Recent attempts to enhance the therapeutic efficiency of ionizing radiation have produced promising results. In this review article, we discuss the development of novel therapeutic strategies for tumor sensitization to radiation therapy. These innovative approaches incorporate the involvement of the immune response and the role of cancer stem cells, as well as direct targeting of signal transduction pathways. Taken together, these concerted efforts demonstrate that the augmentation of radiotherapeutic efficacy results in significantly improved control not only of local disease, but also of metastatic spread and improved overall patient survival.

TI Coronary artery calcium is associated with degree of stenosis and surface irregularity of carotid artery SO ATHEROSCLEROSIS LA English DT Article DE Calcium; Coronary artery; Carotid arteries; Ischemic stroke ID ATHEROSCLEROSIS MESA; NORTHERN MANHATTAN; ISCHEMIC-STROKE; CALCIFICATION; PLAQUE; RISK; ROTTERDAM; CT; PREDICTION; RACE AB Objectives: Carotid stenosis and plaque stability are critical determinants of risk for ischemic stroke. The aim of this study is to elucidate the association of CAC with carotid stenosis and plaque characteristics. Methods: We examined data from the Multi-Ethnic Study of Atherosclerosis (MESA), a prospective cohort study of subclinical cardiovascular disease in multiethnic participants (N = 6814). The association between CAC measured by computed tomography and carotid ultrasonography of carotid plaque was examined using multiple logistic linear models adjusting for traditional vascular risk factors including ethnicity. We also developed ethnic specific models to compare the relationship between CAC and carotid disease across the four ethnicities. Results: Significant carotid stenosis was associated with the presence of CAC (OR 1.73; 95% CI, 1.20-2.49) and log-transformed Agatston score (OR per 1 point increase, 1.18; 95% CI 1.04-1.35). Overt carotid stenosis was also associated with the presence of CAC (OR, 2.34; 95% CI, 1.93-2.83) and log-transformed Agatston score (OR per 1 point increase, 1.53; 95% CI 1.38-1.69). Irregular plaque surface was associated with the presence of CAC (OR, 1.87; 95% CI 1.50-2.32) and the log-transformed Agatston score (OR per 1 point 1 increase, 1.31; 95% CI 1.16-1.48). Associations between CAC and stenosis/stability were not different across ethnicities. Conclusions: Both the presence of CAC and log-transferred Agatston score are independently associated with significant/overt carotid stenosis and carotid plaque surface irregularity regardless of ethnicity. The subjects with a positive or increased CAC score are more likely to have carotid disease potentially increasing their risk for future ischemic stroke. (C) 2012 Elsevier Ireland Ltd.

All DNA transactions (such as transcription, DNA replication and chromosomal segregation) are necessarily linked to strong changes in the topological state of the double helix known as torsional stress or supercoiling. As virtually all DNA transactions are in turn affected by the torsional state of DNA, these changes have the potential to serve as regulatory signals detected by protein partners. This two-way relationship indicates that DNA dynamics may contribute to the regulation of many events occurring during cell life. In this review we will focus on the role of DNA supercoiling in the cellular processes, with particular emphasis on transcription. Besides giving an overview on the multiplicity of factors involved in the generation and dissipation of DNA torsional stress, we will discuss recent studies which give new insight into the way cells use DNA dynamics to perform functions otherwise not achievable.

We define such a set of overlapping positions as a "position cluster", and the 5S RNA gene positioning sequence is presented as an example. The notable exception is the synthetic 601-sequence, which can position a nucleosome perfectly in vitro, though not in vivo. Many years ago, we demonstrated that nucleosome position clusters are present on the CUP1 and HIS3 genes in native yeast chromatin. Recently, using genome-wide paired-end sequencing of nucleosomes, we have shown that position clusters are the general rule in yeast chromatin, not the exception. We argue that, within a cell population, one of several alternative nucleosomal arrays is formed on each gene. We show how position clusters and alternative arrays can give rise to typical nucleosome occupancy profiles, and that position clusters are disrupted by transcriptional activation. The centromeric nucleosome is a rare example of perfect positioning in vivo. It is, however, a special case, since it contains the centromeric histone H3 variant instead of normal H3. Perfect positioning might be due to centromeric sequence-specific DNA binding proteins. Finally, we point out that the existence of position clusters implies that the putative nucleosome code is degenerate. We suggest that degeneracy might be a crucial point in the debate concerning the code. This article is part of a Special Issue entitled: Chromatin in time and space. Published by Elsevier B.V.

Barrier elements block the propagation of heterochromatic structures into adjacent euchromatin. Enhancer blocking elements interfere with interaction between an enhancer and promoter when placed between them. We have dissected a compound insulator element found at the 5' end of the chicken beta-globin locus, which possesses both activities. Barrier insulation is mediated by two kinds of DNA binding proteins: USF1/USF2, a heterodimer which recruits multiple enzyme complexes capable of marking histone on adjacent nucleosomes with 'activating' marks, and Vezf1, which protects against DNA methylation. We have found that the heterochromatic region upstream of the insulator element is maintained in its silent state by a dicer-dependent mechanism, suggesting a mechanism for Vezf1 function in the insulator. Enhancer blocking function in the p-globin insulator element is conferred by a binding site for CTCF. Consistent with this property, CTCF binding was found some years ago to be essential for imprinted expression at the lgf2/H19 locus. Work in many laboratories has since demonstrated that CTCF helps stabilize long-range interactions in the nucleus. We have recently shown that in the case of the human insulin locus such an interaction, over a distance of similar to 300 kb, can result in stimulation of a target gene which itself is important for insulin secretion.

The development of novel techniques to examine the dynamic behavior of transcription factors and the analysis of transcriptional activity at the single cell level with increased temporal resolution has revealed unexpected elements of stochasticity and dynamics of this process. Emerging research reveals a complex picture, wherein a wide range of time scales and temporal transcription patterns overlap to generate transcriptional programs. The challenge now is to develop a perspective that can guide us to common underlying mechanisms, and consolidate these findings. Here we review the recent literature on temporal dynamics and stochastic gene regulation patterns governed by intrinsic or extrinsic signals, utilizing the glucocorticoid receptor (GR)-mediated transcriptional model to illustrate commonality of these emerging concepts.

In vivo data suggests that elongating polymerases exhibit heterogeneity throughout the gene body, suggestive of changes in elongation rate and/or pausing. Here, we review evidence from a variety of different experimental approaches for understanding regulation of transcription elongation. We compare steady-state measurements of nascent RNA density and polymerase occupancy to time-resolved measurements and point out areas of disagreement.

The majority of introns in higher eukaryotes are excised prior to transcript release in a manner that is dependent on transcription through pot II. As a result of co-transcriptional splicing, variations in pol II elongation influence alternative splicing patterns, wherein a slower elongation rate is associated with increased inclusion of alternative exons within mature mRNA. Physiological barriers to pol II elongation, such as repressive chromatin structure, can thereby similarly impact splicing decisions. Surprisingly, pre-mRNA splicing can reciprocally influence pol II elongation and chromatin structure. Here, we highlight recent advances in co-transcriptional splicing that reveal an extensive network of coupling between splicing, transcription and chromatin remodeling complexes.

One interesting observation was the high frequency of bidirectional promoters characterized by two protein encoding genes whose promoters are arranged in a divergent or "head-to-head" configuration with less than 2000 base pairs of intervening sequence. Computational estimates published by various groups indicate that nearly 10% of the coding gene promoters are arranged in such a manner and the extent of this bias is a unique feature of mammalian genomes. Moreover, as a class, head-to-head promoters appear to be enriched in specific categories of gene function. Here we review the structure, composition, genomic properties and functional classifications of genes controlled by bidirectional promoters and explore the biological implication of these features.

Error-prone transcription has been proposed to contribute to cancer, aging, adaptive mutagenesis, and mutagenic evolution of retroviruses and retrotransposons. The mechanisms controlling transcription fidelity and the biological consequences of transcription errors are poorly understood. Because of the transient nature of mRNAs and the lack of reliable experimental systems, the identification and characterization of defects that increase transcription errors have been particularly challenging. In this review we describe novel genetic screens for the isolation of fidelity mutants in both Saccharomyces cerevisiae and Escherichia coli RNA polymerases. We obtained and characterized two distinct classes of mutants altering NTP misincorporation and transcription slippage both in vivo and in vitro. Our study not only validates the genetic schemes for the isolation of RNA polymerase mutants that alter fidelity, but also sheds light on the mechanism of transcription accuracy.

Packaging of promoter DNA into chromatin can greatly impact the ability of RNA polymerase II to access and transcribe a gene. Promoter chromatin environments thus play a central role in establishing transcriptional output appropriate for specific environmental conditions or developmental states. Recent genomic studies have illuminated general principles of chromatin organization and deepened our understanding of how promoter sequence and nucleosome architecture may impact gene expression. Concurrently, pausing of polymerase during early elongation has been recognized as an important event influencing transcription of genes within stimulus-responsive networks. Promoters regulated by pausing are now recognized to possess a distinct chromatin architecture that may facilitate the plasticity of gene expression in response to signaling events. Here we review advances in understanding chromatin and pausing, and explore how coupling Pol II pausing to distinct promoter architectures may help organisms achieve flexible yet precise transcriptional control.

Chromatin remodeling is an essential component of SR signaling, and defining the process of chromatin and nucleosome remodeling during signaling is critical to the continued development of related therapies. The glucocorticoid receptor (GR) is a key SR that activates numerous promoters including the well defined MMTV promoter. The activation of MMTV by GR provides an excellent model for teasing apart the sequence of events between hormone treatment and changes in gene expression. Comparing hormone-induced transcription from stably integrated promoters with defined nucleosomal structure to that from transiently expressed, unstructured promoters permits key distinctions between interactions that require remodeling and those that do not. The importance of co-activators and histone modifications prior to remodeling and the formation of the preinitiation complex that follows can also be clarified by defining key transition points in the propagation of hormonal signals. Combined with detailed mapping of proteins along the promoter, a temporal and spatial understanding of the signaling and remodeling processes begins to emerge. In this review, we examine SR signaling with a focus on GR activation of the MMTV promoter. We also discuss the ATP-dependent remodeling complex SWI/SNF, which provides the necessary remodeling activity during GR signaling and interacts with several SRs. BRG1, the central ATPase of SWI/SNF, also interacts with a set of BAF proteins that help determine the specialized function and fine-tuned regulation of BRG1 remodeling activity. BRG1 regulation comes from its own subdomains as well as its interactive partners. In particular, the HSA domain region of BRG1 and unique features of its ATPase homology appear to play key roles in regulating remodeling function. Details of the inter-workings of this chromatin remodeling protein continue to be revealed and promise to improve our understanding of the mechanism of chromatin remodeling during steroid hormone signaling.

Recent years have witnessed an explosive expansion of the list of remarkably site-specific histone methyltransferases and demethylases, which greatly facilitates the study on the biological functions of histone methylation in gene expression and cell differentiation in mammalian cells. Adipogenesis represents an excellent model system to understand transcriptional and epigenetic regulation of gene expression and cell differentiation. While transcriptional regulation of adipogenesis has been extensively studied, the roles of epigenetic mechanisms in particular histone methylation in regulation of adipogenesis have just begun to be understood. This review will summarize the recent progress on epigenetic regulation of adipogenesis by histone methylation, with a focus on histone H3K4 and H3K27. The available evidence suggests that site-specific histone methylations play critical roles in adipogenesis and control the expression of both positive and negative master regulators of adipogenesis.

While it is clear during lymphocyte development that H3K4me3 plays a critical role in targeting and stimulating RAG1/2 recombinase activity for V(D)J recombination, recent work suggests roles for this histone mark and different MU-like complexes in mature B cells during immunoglobulin class-switch recombination. In this review, we focus our discussion to advances on how MLL-like complexes and H3K4 methylation may function during the germ-line transcription and recombinase targeting steps of class-switch recombination.

This duality contrasts to genetic information, which is essentially static and identical in every cell in an organism with only a few exceptions such as immunoglobulin genes in lymphocytes. Epigenetics is traditionally perceived as a means to regulate gene expression without a change in DNA sequence. This, however, does not exclude a potential role for genetic variations in providing differential backgrounds on which epigenetic modulations and their regulatory consequences are achieved. An effective approach to investigating the interplay between genetic variations and epigenetic variations is through allele-specific analysis of epigenetics and gene expression. Such studies have generated many new insights into functions of genetic variations, mechanisms of gene expression regulation, and the role of mutations and epigenetic alterations in human cancer.

The efficient recognition and faithful repair of DNA damage, particularly double-strand damage, is essential for genomic stability and cellular homeostasis. Imperfect repair of DNA double-strand breaks (DSBs) can lead to oncogenesis. The efficient repair of DSBs relies in part on the rapid formation of foci of phosphorylated histone H2AX (gamma-H2AX) at each break site, and the subsequent recruitment of repair factors. These foci can be visualized with appropriate antibodies, enabling low levels of DSB damage to be measured in samples obtained from patients. Such measurements are proving useful to optimize treatments involving ionizing radiation, to assay in vivo the efficiency of various drugs to induce DNA damage, and to help diagnose patients with a variety of syndromes involving elevated levels of gamma-H2AX We will survey the state of the art of utilizing gamma-H2AX in clinical settings. We will also discuss possibilities with other histone post-translational modifications. The ability to measure in vivo the responses of individual patients to particular drugs and/or radiation may help optimize treatments and improve patient care.

In this way, DNA methylation controls gene expression and plays a role in ES cell regulation, tissue differentiation and the development of the organism. In abnormal circumstances methylation can also induce diseases and promote cancer progression. Chromatin remodeling proteins such as the SNF2 family member Lsh regulates genome-wide cytosine methylation patterns during mammalian development. Lsh promotes methylation by targeting and repressing repeat sequences that are imbedded in heterochromatin. Lsh also regulates cytosine methylation at unique loci. Alterations in histone modifications (such as H3K4me3, histone acetylation, H3K27me3 and H2Aub) can be associated with DNA methylation changes making Lsh-mediated cytosine methylation part of a larger epigenetic network defining gene expression and cellular differentiation during development.

In mammals it is essential for accurate regulation of gene expression and normal development. Mammalian genomes are depleted for the CG dinucleotide, a result of the chemical deamination of methyl-cytosine in CG resulting in TpG. Most CG dinucleotides are methylated, but similar to 15% are unmethylated. Five percent of CGs cluster into similar to 20,000 regions termed CG islands (CGI) which are generally unmethylated. About half of CGIs are associated with housekeeping genes. In contrast, the gene body, repeats and transposable elements in which CGs are generally methylated. Unraveling the epigenetic machinery operating in normal cells is important for understanding the epigenetic aberrations that are involved in human diseases including cancer. With the advent of high-throughput sequencing technologies, it is possible to identify the CG methylation status of all 30 million unique CGs in the human genome, and monitor differences in distinct cell types during differentiation and development. Here we summarize the present understanding of DNA methylation in normal cells and discuss recent observations that CG methylation can have an effect on tissue specific gene expression. We also discuss how aberrant CG methylation can lead to cancer. This article is part of a Special Issue entitled: Chromatin in time and space. Published by Elsevier B.V.

It prevents the recognition of natural chromosome ends as DNA breaks (the end capping function). It counteracts incomplete end replication by adding DNA to the ends of chromosomes (the end elongation function). In most organisms studied, telomerase fulfills the end elongation function. In Drosophila, however, telomere specific retrotransposons have been coerced into performing this essential function for the host. In this review, we focus our discussion on transposition mechanisms and transcriptional regulation of these transposable elements, and present provocative models for the purpose of spurring new interests in the field.

Recent advances in centromere research have led to identification of many kinetochore components, such as the centromeric-specific histone H3 variant, CenH3, and its interacting partner, Scm3. Both are essential for chromosome segregation and are evolutionarily conserved from yeast to humans. CenH3 is proposed to be the epigenetic mark that specifies centromeric identity. Molecular mechanisms that regulate the assembly of kinetochores at specific chromosomal sites to mediate chromosome segregation are not fully understood. In this review, we summarize the current literature and discuss results from our laboratory, which show that restricting the localization of budding yeast CenH3, Cse4, to centromeres and balanced stoichiometry between Scm3 and Cse4, contribute to faithful chromosome transmission. We highlight our findings that, similar to other eukaryotic centromeres, budding yeast centromeric histone H4 is hypoacetylated, and we discuss how altered histone acetylation affects chromosome segregation.

Such aneuploidies result in tumor specific genomic copy number alterations. The patterns of genomic imbalances are tumor specific, and to a certain extent specific for defined stages of tumor development. Genomic imbalances occur already in premalignant precursor lesions. i.e., before the transition to invasive disease, and their distribution is maintained in metastases, and in cell lines derived from primary tumors. These observations are consistent with the interpretation that tumor specific genomic imbalances are drivers of malignant transformation. Naturally, this precipitates the question of how such imbalances influence the expression of resident genes. A number of laboratories have systematically integrated copy number alterations with gene expression changes in primary tumors and metastases, cell lines, and experimental models of aneuploidy to address the question as to whether genomic imbalances deregulate the expression of one or few key genes, or rather affect the cancer transcriptome more globally. The majority of these studies showed that gene expression levels follow genomic copy number. Therefore, gross genomic copy number changes, including aneuploidies of entire chromosome arms and chromosomes, result in a massive deregulation of the transcriptome of cancer cells.

Mapping replication initiation sites can provide clues for the coordination of DNA replication and transcription on a whole-genome scale. Here we discuss recent insights obtained from genome-scale analyses of replication initiation sites and transcription in mammalian cells and ask how transcription and chromatin modifications affect the frequency of replication initiation events. We also discuss DNA sequences, such as insulators and replicators, which modulate replication and transcription of target genes, and use genome-wide maps of replication initiation sites to evaluate possible commonalities between replicators and chromatin insulators.

In the case of the FXDs, pathology results from expansion of CGG center dot CCG-repeat tract in the 5' UTR of the FMR1 gene, while pathology in FRDA results from expansion of a GAA center dot TTC-repeat in intron 1 of the FXN gene. Expansion occurs during gametogenesis or early embryogenesis by a mechanism that is not well understood. Associated Expansion then produces disease pathology in various ways that are not completely understood either. In the case of the FXDs, alleles with 55-200 repeats express higher than normal levels of a transcript that is thought to be toxic, while alleles with >200 repeats are silenced. In addition, alleles with >200 repeats are associated with a cytogenetic abnormality known as a fragile site, which is apparent as a constriction or gap in the chromatin that is seen when cells are grown in presence of inhibitors of thymidylate synthase. FRDA alleles show a deficit of the FXN transcript. This review will address the role of repeat-mediated chromatin changes in these aspects of FXD and FRDA disease pathology.
