Fat-1 transgenic cattle have high levels of ω-3 fatty acids, which regulate several genes in fatty acid metabolism. In the current study, fibroblasts derived from in vivo fertilized (Ferti) and fat-1 transgenic (TG) Luxi cattle (Bos taurus), a local breed in China, were cultured and their miRNA expression was characterized. Expression of 352 known miRNAs differed in cells from Ferti and TG cattle:...
To determine the frequency of the genotypes of single nucleotide polymorphisms (SNPs) in the gene encoding cholesteryl ester transfer protein (CETP) and their associations with age-related macular degeneration (AMD) in the Lithuanian population.A total of 1264 subjects were examined: 251 patients with early AMD, 206 patients with exudative AMD, and 807 healthy controls.The genotyping of CETP (rs5882,...
Epigenetic modifications regulate plant genes to cope with a variety of environmental stresses. Chorispora bungeana is an alpine subnival plant with strong tolerance to multiple abiotic stresses, especially cold stress. In this study, we characterized the alcohol dehydrogenase 1 gene from Chorispora bungeana, CbADH1, that is up-regulated in cold conditions. Overexpression of CbADH1 in Arabidopsis...
Genetic defect is a major cause of early miscarriage, but still in many cases the etiology are not fully understood. Recent studies have shown that dysregulation of genes in placenta tissue are participated in the pathogenesis of unexplained early miscarriage. The aim of our study is to explore mRNA expression profile in placental chorionic villi and to reveal the underlying mechanism of unexplained...
African ancestry and obesity are associated with higher risk of prostate cancer (PC). In a pilot study, we explored interactions between obesity (as measured by waist to hip ratio (WHR)) and inflammatory SNPs in relation to PC risk among Jamaican men. This study evaluated 87 chemokine and cytokine associated SNPs in obese and normal weight cases (N=109) and controls (N=102) using a stepwise penalized...
T cell-mediated anti-tumor immunity plays a pivotal role in cancer immune surveillance. Cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) is a protein receptor mainly expressed in activated T cells and regulatory T cells. CTLA-4 competes with CD28 for ligand binding and generates inhibitory signals to attenuate T cell activation. The blockade of CTLA-4 mediated immune inhibitory checkpoint has...
Tissue specific stem cells are indispensable contributors to adult tissue maintenance, repair, and regeneration. In skeletal muscle, satellite cells (SCs) are the resident muscle stem cell population and are required to maintain skeletal muscle homeostasis throughout life. Increasing evidence suggests that SCs are a heterogeneous cell population with substantial biochemical and functional diversity...
To investigate the molecular mechanism underlying differential lipid deposition between intramuscular (IM) and subcutaneous (SC) fat tissues of pigs, peroxisome proliferator-activated receptor gamma (PPARG) expression levels were compared in these two types of adipose tissues. The results showed that both mRNA and protein levels of PPARG were significantly higher in SC fat than in IM fat. Correspondingly,...
Permanently frozen (approx. 3.5Ma) alluvial Neogene sediments exposed in the Aldan river valley at the Mammoth Mountain (Eastern Siberia) are unique, ancient, and poorly studied permafrost environments. So far, the structure of the indigenous bacterial community has remained unknown. Use of 16S metagenomic analysis with total DNA isolation using DNA Spin Kit for Soil (MO-Bio) and QIAamp DNA Stool...
In this study, an α-carbonic anhydrase (α-CA), HcCA3, from Hyriopsis cumingii was characterized. The full-length cDNA of HcCA3 was 1628bp, including a CA domain and an ORF of 1053bp which encoded 350 amino acids. Its predicted molecular weight was 39.69kDa and the pI was 5.92. qRT-PCR was used to determine the expression of the gene in various tissues at 0h, 3h, 6h, 12h, 24h, 48h, 96h, 7d, 14d, 21d,...
The human cytokine precursor ECRG4 has been associated with multiple physiological, developmental and pathophysiological processes involving cell proliferation, cell migration, innate immunity, inflammation, cancer progression and metastases. Although down-regulation of ECRG4 gene expression has been largely attributed to hypermethylation of CpG islands in the 5’untranslated region of the ECRG4 promoter,...
Polymorphism in vitamin D binding protein gene may have an impact on serum vitamin D transport and thus may have relation with type 2 diabetes mellitus. In our study, we investigated the association of serum vitamin D level and vitamin D-binding protein gene polymorphism with the onset of type 2 diabetes mellitus.Blood samples were collected from 104 type 2 diabetic patients and 107 healthy volunteers...
MiRNAs have emerged as key regulators of skeletal muscle development, but the knowledge of miRNAs in the molecular network of muscle development remains poorly understood. In this study, we designed to examine the biological function of bovine-miR-101-1. The bovine miR-101-1 was detected in the skeletal muscle of fetal, calf and adult cattle. Its abundance was significantly higher in the skeletal...
Liver fibrosis, characterized with the excessive accumulation of extracellular matrix (ECM) proteins, represents the final common pathway of chronic liver inflammation. Ever-increasing evidence indicates microRNAs (miRNAs) dysregulation has important implications in the different stages of liver fibrosis. However, our knowledge of miRNA-gene regulation details pertaining to such disease remains unclear...
