Weaver gene plays an essential physiological role in the function of many organs, including brain, heart, kidney and endocrine cells, and also in the regulation of insulin secretion by glucose and/or neurotransmitters. Thus, weaver gene is an important potential candidate gene effecting on performance traits. The objective of this study was to detect the(More)
MicroRNAs (miRNAs) are a family of ~22 nucleotide small RNA molecules that regulate gene expression by fully or partially binding to their complementary sequences. Recently, a large number of miRNAs and their expression patterns have been identified in various species. However, to date no miRNAs have been reported to modulate muscle development in beef(More)
The F-box protein 32 (FBXO32), also known as Atrogin-1, is one of the four subunits of the ubiquitin protein ligase complex. FBXO32 has been previously shown to be involved in regulation of initiation and development of muscle mass. In the present study, we investigated the polymorphism of FBXO32 gene in 1313 cattle from seven bovine breeds using DNA(More)
The peroxisome proliferator-activated receptor gamma coactivator-1 alpha protein, encoded by the PPARGC1A gene, is a metabolic switch, which transcriptionally activates a complex pathway of mitochondrial biogenesis, lipid and glucose metabolism. Three SNPs (exon 3 c.396G>A, intron 9 c.1892 + 19C>T and exon 10 c.1971C>T) were found and identified in three(More)
Adiponectin modulates lipid and glucose metabolism in adipose tissues and is also related to bone metabolism. Polymorphisms in the ADIPOQ gene likely have an impact on growth traits in cattle. In this study, we examined the relationship between ADIPOQ polymorphisms and body measurement parameters in Chinese beef cattle. First, we sequenced ADIPOQ and 1.2 kb(More)
Monoacylglycerol acyltransferase 2 (MGAT2), as a candidate gene for quantitative traits, relates to dietary fat uptake, lipids synthesis and storage, which plays a major role in the absorption of dietary fat by catalyzing the resynthesis of triacylglycerol in enterocytes. In this study, based on DNA pool sequencing and PCR-RFLP methods, polymorphisms of the(More)
The aim of this study was to detect mutations of the nuclear factor I/X (Nfix) gene and examine the association of its polymorphisms with growth traits in cattle. Six sequence variants (SVs) including five single-nucleotide mutations and an indel with multiple alleles were detected, among which four polymorphisms within the Nfix gene were identified in 1159(More)
Forkhead box A2 (Foxa2) has been recognized as one of the most potent transcriptional activators that is implicated in the control of feeding behavior and energy homeostasis. However, similar researches about the effects of genetic variations of Foxa2 gene on growth traits are lacking. Therefore, this study detected Foxa2 gene polymorphisms by DNA pool(More)
