Abstract Background: Epstein-Barr virus (EBV) presumably plays an important role in the pathogenesis of nasopharyngeal carcinoma (NPC), but the molecular mechanism of EBV-dependent neoplastic transformation is not well understood. The combination of bioinformatics with evidences from biological experiments paved a new way to gain more insights into the molecular mechanism of cancer. Results: We profiled gene expression using a meta-analysis approach. Two sets of meta-genes were obtained. Meta-A genes were identified by finding those commonly activated/deactivated upon EBV infection/reactivation. -

Unveiling Genomic Regions That Underlie Differences Between Afec-Assaf Sheep and Its Parental Awassi Breed
Seroussi et al. Genet Sel Evol (2017) 49:19 DOI 10.1186/s12711-017-0296-3 Genetics Selection Evolution RESEARCH Open Access Unveiling genomic regions that underlie differences between Afec‑Assaf sheep and its parental Awassi breed Eyal Seroussi, Alexander Rosov, Andrey Shirak, Alon Lam and Elisha Gootwine* Abstract Background: Sheep production in Israel has improved by crossing the fat-tailed local Awassi breed with the East Friesian and later, with the Booroola Merino breed, which led to the formation of the highly prolific Afec-Assaf strain. This strain differs from its parental Awassi breed in morphological traits such as tail and horn size, coat pigmentation and wool characteristics, as well as in production, reproductive and health traits. To identify major genes associated with the formation of the Afec-Assaf strain, we genotyped 41 Awassi and 141 Afec-Assaf sheep using the Illumina Ovine SNP50 BeadChip array, and analyzed the results with PLINK and EMMAX software. The detected variable genomic regions that differed between Awassi and Afec-Assaf sheep (variable genomic regions; VGR) were compared to selection signatures that were reported in 48 published genome-wide association studies in sheep. Because the Afec-Assaf strain, but not the Awassi breed, carries the Booroola mutation, association analysis of BMPR1B used as the test gene was performed to evaluate the ability of this study to identify a VGR that includes such a major gene. Results: Of the 20 detected VGR, 12 were novel to this study. A ~7-Mb VGR was identified on Ovies aries chromo- some OAR6 where the Booroola mutation is located. -

Here, we present in detail the current structural knowledge surrounding the individual components of the complex, binding sites, and dynamics during the activation process. A novel kinase triggering mechanism, the ‘bow-arrow model’, is proposed based on current knowledge and computational simulations of this system, in which insulin, after its initial interaction with binding site 1, engages with site 2 between the fibronectin type III (FnIII)- 1 and -2 domains, which changes the conformation of FnIII-3 and eventually translates into structural changes across the membrane. This model provides a new perspective on the process of insulin binding to its receptor and, thus, could lead to future novel drug discovery efforts. Introduction upon insulin binding [8].

They are found at telomeres, centrosomes, nuclear pores and the Golgi- apparatus, and participate in telomere length regulation and resolution of sister chromatid association. Their other function(s) are unknown and it has been difficult to envision a common role at such diverse cellular locations. We isolated the chicken tankyrase homologs and examined their interaction partners, subcellular location and domain functions to learn more about their mode of action. Cross-species sequence comparison indicated that tankyrase domain structure is highly conserved and supports division of the ankyrin domain into five subdomains, each separated by a highly conserved LLEAAR/K motif. GST-pull down experiments demonstrated that the ankyrin domains of both proteins interact with chicken TRF1. Analysis of total cellular and nuclear proteins showed that cells contain approximately twice as much tankyrase 1 as tankyrase 2. -
