Anne Spence, and Pamela Flodman Department of Pediatrics, University of California, Irvine, California In this review we will evaluate evidence that altered gene dosage and structure im- pacts neurodevelopment and neural connectivity through deleterious effects on synap- tic structure and function, and evidence that the latter are key contributors to the risk for autism. We will review information on alterations of structure of mitochondrial DNA and abnormal mitochondrial function in autism and indications that interactions of the nuclear and mitochondrial genomes may play a role in autism pathogenesis. In a final section we will present data derived using Affymetrixtm SNP 6.0 microar- ray analysis of DNA of a number of subjects and parents recruited to our autism spectrum disorders project. We include data on two sets of monozygotic twins. Col- lectively these data provide additional evidence of nuclear and mitochondrial genome imbalance in autism and evidence of specific candidate genes in autism. We present data on dosage changes in genes that map on the X chromosomes and the Y chro- mosome. -

13Type 2 Diabetes Genetics: Beyond GWAS
abetes & Di M f e o t a l b a o Sang and Blackett, J Diabetes Metab 2012, 3:5 n l r i s u m o DOI: 10.4172/2155-6156.1000198 J Journal of Diabetes and Metabolism ISSN: 2155-6156 Review Article Open Access Type 2 Diabetes Genetics: Beyond GWAS Dharambir K. Sanghera* and Piers R. Blackett University of Oklahoma Health Sciences Center, Oklahoma City, USA Abstract The global epidemic of type 2 diabetes mellitus (T2D) is one of the most challenging problems of the 21st century and the fifth leading cause of death worldwide. Substantial evidence suggests that T2D is a multifactorial disease with a strong genetic component. Recent genome-wide association studies (GWAS) have successfully identified and replicated nearly 75 susceptibility loci associated with T2D and related metabolic traits, mostly in Europeans, and some in African, and South Asian populations. The GWAS serve as a starting point for future genetic and functional studies since the mechanisms of action by which these associated loci influence disease is still unclear and it is difficult to predict potential implication of these findings in clinical settings. Despite extensive replication, no study has unequivocally demonstrated their clinical role in the disease management beyond progression to T2D from impaired glucose tolerance. However, these studies are revealing new molecular pathways underlying diabetes etiology, gene-environment interactions, epigenetic modifications, and gene function. This review highlights evolving progress made in the rapidly moving field of T2D genetics that is starting to unravel the pathophysiology of a complex phenotype and has potential to show clinical relevance in the near future. -

The Role of Type I Interferon in the Immunobiology of Chikungunya Virus
The role of type I interferon in the immunobiology of chikungunya virus Jane Amelia Clare Wilson B. App. Sc. (Human Biology), B. App. Sc. (Hons) A thesis submitted for the degree of Doctor of Philosophy at The University of Queensland in 2015 School of Medicine & QIMR Berghofer Medical Research Institute I Abstract Chikungunya virus (CHIKV) is a mosquito-transmitted alphavirus that can cause explosive outbreaks of a febrile, arthritic/arthralgic disease usually lasting weeks to months, and in rare cases, more than a year. In 2004, the largest ever CHIKV outbreak began in Kenya, spreading to islands of the Indian Ocean, India, South East Asia and major outbreaks have recently occurred in the South Pacific Islands and the Caribbean. The host type I interferon (IFN) response is crucial for effective control of CHIKV infection. Herein, the dynamics, source and responses generated by the type I IFNs following CHIKV infection were investigated. Interferon regulatory factors 3 (IRF3) and IRF7 are key transcription factors for the type I IFN response. While CHIKV infection of wild-type mice is non-lethal, infection of mice deficient in both IRF3 and IRF7 (IRF3/7-/-) resulted in mortality, illustrating that these factors are essential for protection. Using knockout mice for the adaptor molecules upstream of IRF3 and 7, IPS1 was found to be the most important for type I IFN production, with TRIF and MyD88 also contributing to the response. Mortality in IRF3/7-/- mice was also associated with type I IFN suppression of pathological levels of IFNγ and haemorrhagic shock. Heterozygous reporter mice, in which eGFP was expressed under the control of either the IFNβ or the IFNα6 promoter on one chromosome, were employed to try and identify the cellular source of type I IFN production following CHIVK infection. -
Defining Functional Interactions During Biogenesis of Epithelial Junctions
ARTICLE Received 11 Dec 2015 | Accepted 13 Oct 2016 | Published 6 Dec 2016 | Updated 5 Jan 2017 DOI: 10.1038/ncomms13542 OPEN Defining functional interactions during biogenesis of epithelial junctions J.C. Erasmus1,*, S. Bruche1,*,w, L. Pizarro1,2,*, N. Maimari1,3,*, T. Poggioli1,w, C. Tomlinson4,J.Lees5, I. Zalivina1,w, A. Wheeler1,w, A. Alberts6, A. Russo2 & V.M.M. Braga1 In spite of extensive recent progress, a comprehensive understanding of how actin cytoskeleton remodelling supports stable junctions remains to be established. Here we design a platform that integrates actin functions with optimized phenotypic clustering and identify new cytoskeletal proteins, their functional hierarchy and pathways that modulate E-cadherin adhesion. Depletion of EEF1A, an actin bundling protein, increases E-cadherin levels at junctions without a corresponding reinforcement of cell–cell contacts. This unexpected result reflects a more dynamic and mobile junctional actin in EEF1A-depleted cells. A partner for EEF1A in cadherin contact maintenance is the formin DIAPH2, which interacts with EEF1A. In contrast, depletion of either the endocytic regulator TRIP10 or the Rho GTPase activator VAV2 reduces E-cadherin levels at junctions. TRIP10 binds to and requires VAV2 function for its junctional localization. Overall, we present new conceptual insights on junction stabilization, which integrate known and novel pathways with impact for epithelial morphogenesis, homeostasis and diseases. 1 National Heart and Lung Institute, Faculty of Medicine, Imperial College London, London SW7 2AZ, UK. 2 Computing Department, Imperial College London, London SW7 2AZ, UK. 3 Bioengineering Department, Faculty of Engineering, Imperial College London, London SW7 2AZ, UK. 4 Department of Surgery & Cancer, Faculty of Medicine, Imperial College London, London SW7 2AZ, UK. -

Abstract: Members of the human Zyxin family are LIM domain-containing proteins that perform critical cellular functions and are indispensable for cellular integrity. Despite their importance, not much is known about their structure, functions, interactions and dynamics. To provide insights into these, we used a set of in-silico tools and databases and analyzed their amino acid sequence, phylogeny, post-translational modifications, structure-dynamics, molecular interactions, and func- tions. Our analysis revealed that zyxin members are ohnologs. Presence of a conserved nuclear export signal composed of LxxLxL/LxxxLxL consensus sequence, as well as a possible nuclear localization signal, suggesting that Zyxin family members may have nuclear and cytoplasmic roles. The molecular modeling and structural analysis indicated that Zyxin family LIM domains share Citation: Siddiqui, M.Q.; Badmalia, similarities with transcriptional regulators and have positively charged electrostatic patches, which M.D.; Patel, T.R. -

Its yearling weight and carcass traits (backfat thickness, carcass weight, eye muscle area, and marbling score) are economically important for the selection of young and proven bulls. In recent decades, the advent of high throughput genotyping technologies has made it possible to perform genome-wide association studies (GWAS) for the detection of genomic regions associated with traits of economic interest in different species. In this study, we conducted a weighted single-step genome-wide association study which combines all genotypes, phenotypes and pedigree data in one step (ssGBLUP). It allows for the use of all SNPs simultaneously along with all phenotypes from genotyped and ungenotyped animals. Our results revealed 33 relevant genomic regions related to the traits of interest. -

ABSTRACT Family with sequence similarity 46 member C (FAM46C) is a non-canonical poly(A) polymerase that is associated with tumorigenesis. However, its role in prostate cancer development is not fully understood. Herein, we determined expression pattern of FAM46C in prostate cancer and further identified its effect on the tumorigenesis and chemosensitivity. FAM46C expression was decreased in prostate cancer tissues and cell lines compared with corresponding controls.
