Efforts have been made to characterize the high-altitude adaption in Tibetan pigs and identified vast of genes or genomic regions undergone natural selection. Nonetheless, information concerning gene expression and DNA methylation changes response to low-altitude acclimation in Tibetan pigs is long overdue. To explore the exceptional mechanisms of gene expression and DNA methylation that are induced...
Accumulating evidence has indicated that microRNAs (miRNAs) and endoplasmic reticulum (ER) stress play critical roles in myoblast differentiation. However, the regulation roles of miRNAs and ER stress in myogenic differentiation have not been fully revealed and need to be further studied. Here, we discovered that the expression levels of miR-181a-5p were strongly upregulated during C2C12 cell differentiation...
Domestication and subsequent selective pressures have produced a large variety of pig coat colors in different regions and breeds. The melanocortin 1 receptor (MC1R) gene plays a crucial role in determining coat color of mammals. Here, we investigated genetic diversity and selection at the coding region of the porcine melanocortin receptor 1 (MC1R) in Tibetan pigs and Landrace pigs. By contrast, genetic...
Domestic goats are distributed in a wide range of habitats and have acclimated to their local environmental conditions. To investigate the gene expression changes of goats that are induced by high altitude stress, we performed RNA-seq on 27 samples from the three hypoxia-sensitive tissues (heart, lung, and skeletal muscle) in three indigenous populations from distinct altitudes (600m, 2000m, and 3000m)...
Polymorphisms in the endothelial nitric oxide synthase (eNOS) gene may influence the risk of ischemic stroke (IS), but the results are still debatable. A meta-analysis was performed to investigate the association between the eNOS gene polymorphisms in IS risk. Case–control studies on the association between the G894T, T-786C, and 4b/a polymorphisms and IS were searched up to July 2012, and the genotype...
