Gene expression is initiated by the binding of transcription factors to cis-regulatory modules such as enhancer elements binding to the Serine/Arginine proteins. Recently, we noticed an increased ability to identify the location as well as the motifs of enhancers using genome-wide information on spliceosomal factor occupancy, cofactor recruitment and chromatin modifications. In this study, we have...
In the present study, we characterized the transcriptional regulatory region (KF038144) controlling the expression of a constitutive FAD2 in Brassica napus. There are multiple FAD2 gene copies in B. napus genome. The FAD2 gene characterized and analyzed in the study is located on chromosome A5 and was designated as BnFAD2A5-1. BnFAD2A5-1 harbors an intron (1192bp) within its 5′-untranslated region...
The RUNX1/AML1 gene is among the most frequently mutated genes in human leukaemia. However, its association with T-cell acute lymphoblastic leukaemia (T-ALL) remains poorly understood. In order to examine RUNX1 point mutations in T-ALL, we conducted an amplicon-based deep sequencing in 65 Southeast Asian childhood patients and 20 T-ALL cell lines, and detected RUNX1 mutations in 6 patients (9.2%)...
Recent studies suggested that resting heart rate (RHR) might be an independent predictor of cardiovascular mortality and morbidity. Nonetheless, the interrelation between RHR and cardiovascular diseases is not clear. In order to resolve this puzzle, the importance of genetic determinants of RHR has been recently suggested, but it needs to be further investigated.The aim of this study was to estimate...
Vitamin-D has pleiotropic effects on calcium and bone metabolism, cellular growth control, cell differentiation and modulation of both innate and acquired immune response. Previous studies revealed the association of vitamin-D receptor gene (VDR) polymorphism with infection diseases including HIV-1 infection. To assess for association between polymorphisms of vitamin-D pathway genes CYP27B1, vitamin-D...
Germ cells of diverse animal species have a unique membrane-less organelle called germ plasm (GP). GP is usually associated with mitochondria and contains RNA binding proteins and mRNAs of germ genes such as vasa. GP has been described as the mitochondrial cloud (MC), intermitochondrial cement (IC) and chromatoid body (CB). The mechanism underlying varying GP structures has remained incompletely understood...
Yeast Rpb4, a subunit of RNA pol II is not essential for viability but is involved in multiple cellular phenotypes such as temperature sensitivity, enhanced pseudohyphal morphology, and decreased sporulation. Both in vivo and in vitro studies strongly support involvement of Rpb4 in transcription initiation, while its role in transcription elongation is not entirely consistent. Here we show that Rpb4...
Homocystinuria is a neurometabolic disease caused by severe deficiency of cystathionine beta-synthase activity, resulting in severe hyperhomocysteinemia. Affected patients present several symptoms including a variable degree of motor dysfunction, being that the pathomechanism is not fully understood. In the present study we investigated the effect of chronic hyperhomocysteinemia on some parameters...
Shaker-like potassium (K + ) channels in plants play an important role in K + absorption and transport. In this study, we characterized a Shaker-like K + channel gene GhAKT1 from the roots of Gossypium hirsutum cv. Liaomian17. Phylogenetic analysis showed that the GhAKT1 belongs to the AKT1-subfamily in the Shaker-like K + channel family. Confocal imaging of a GhAKT1-green...
The Cd247 gene encodes for a transmembrane protein important for the expression and assembly of TCR/CD3 complex on the surface of T lymphocytes. Down-regulation of CD247 has functional consequences in systemic autoimmunity and has been shown to be associated with Type 1 Diabetes in NOD mouse. In this study, we have utilized the wealth of high-throughput sequencing data produced during the Encyclopedia...
Lactose intolerance in northern Europeans is strongly associated with a single-nucleotide polymorphism (SNP) located 14kb upstream of the human lactase gene: −13,910*C/T. We examined whether SNPs in the 5′ flanking region of the pig lactase gene are similar to those in the human gene and whether these polymorphisms play a functional role in regulating pig lactase gene expression. The 5′ flanking region...
In order to discover the variation of microRNAs and genes associated with NF-κB signaling pathway between the healthy and the mastitis Chinese Holstein cows, Illumina Deep Sequencing and qRT-PCR are applied to detect 25 kinds of miRNAs (miR-16, miR-125b, miR-15, miR-29a, miR-23b, miR-146, miR-301a, miR-181b, let-7, miR-30b, miR-21, miR-223, miR-27b, miR-10a, miR-143, etc.) expression levels in blood...
In peroxisome, acyl-coenzyme A oxidase 1 (ACOX1) is the first rate-limiting enzyme of the fatty acid beta-oxidation pathway, which catalyzes the desaturation of acyl-CoAs to 2-trans-enoyl-CoAs. Two isoforms of acyl-coenzyme A oxidase 1 were firstly identified in Nile tilapia (Oreochromis niloticus) in this study. ACOX1 isoform1 (ACOX1i1) and ACOX1 isoform2 (ACOX1i2) were encoded by the single gene...
Mitochondrial genome (mitogenome) can provide information for genomic structure as well as for phylogenetic analysis and evolutionary biology. In this study, we present the complete mitogenome of the atlas moth, Attacus atlas (Lepidoptera: Saturniidae), a well-known silk-producing and ornamental insect with the largest wing surface area of all moths. The mitogenome of A. atlas is a circular molecule...
In this study, we investigated the effects and mechanism of quercetin preconditioning on anti-myocardial ischemia reperfusion (IR) injuries in vivo. Meanwhile, their potential anti-oxidative stress and anti-inflammation effect were assessed. SD rats were orally given quercetin 250mg/kg. Myocardium apoptosis was determined with TUNEL staining. The biomarkers related to myocardial ischemia injury were...
A variety of studies have evaluated the association between the −786T>C polymorphism in the promoter region of endothelial nitric oxide synthase (eNOS) and risk of coronary artery disease (CAD). However, the results remain conflicting. To better understand the role of eNOS −786T>C polymorphism in CAD risk, we conducted a comprehensive systematic review and meta-analysis.Case–control, cohort...
This study is to investigate the role of glucose-regulated protein 78 (GRP78) in the pulmonary microvascular remodeling during hepatopulmonary syndrome (HPS) development.The rat models with liver cirrhosis and HPS were induced by multiple pathogenic factors for 4 to 8wk. The concentrations of alanine transferase (ALT) and endotoxin in plasma were detected in the models, followed by the detection of...
Rumen microbiome represents rich source of enzymes degrading complex plant polysaccharides. We describe here analysis of Carbohydrate Active Enzymes (CAZymes) from 3.5gigabase sequences of metagenomic data from rumen samples of Mehsani buffaloes fed on different proportions of green or dry roughages to concentrate ration. A total of 2597 contigs encoding putative CAZymes were identified by CAZyme...
Mitogen-activated protein kinase (MAPK) cascades are universal signal transduction modules that play essential roles in plant growth, development and stress response. MAPK kinases (MAPKKs), which link MAPKs and MAPKK kinases (MAPKKKs), are integral in mediating various stress responses in plants. However, to date few data about the roles of poplar MAPKKs in stress signal transduction are available...
