The elevation of egg production and the inhibition of incubation behavior are the aims of modern poultry production. Prolactin (PRL) gene is confirmed to be critical for the onset and maintenance of these reproductive behaviors in birds. Through PRL, dopamine D1 receptor (DRD1) was also involved in the regulation of chicken reproductive behavior. However,(More)
The genes that are part of the somatotropic axis play a crucial role in the regulation of growth and development of chickens. The identification of genetic polymorphisms in these genes will enable the scientist to evaluate the biological relevance of such polymorphisms and to gain a better understanding of quantitative traits like growth. In the present(More)
Osteoarthritis (OA) is a degenerative joint disease that affects both cartilage and bone. A better understanding of the early molecular changes in subchondral bone may help elucidate the pathogenesis of OA. We used microarray technology to investigate the time course of molecular changes in the subchondral bone in the early stages of experimental(More)
Graves' disease (GD) is a common autoimmune disease mainly caused by thyroid-stimulating antibodies (TSAbs). Interleukin 21 (IL-21) has recently been reported to play a vital role in the production of pathogenic autoantibodies in several autoimmune diseases, but less is known about GD. This study aimed to investigate the serum levels of IL-21 in GD patients(More)
The age at first egg (AFE), an important indicator for sexual maturation in female chickens, is controlled by polygenes. Based on our knowledge of reproductive physiology, 6 genes including gonadotrophin releasing hormone-I (GnRH-I), neuropeptide Y (NPY), dopamine D2 receptor (DRD2), vasoactive intestinal polypeptide (VIP), VIP receptor-1 (VIPR-1), and(More)
Linkage disequilibrium (LD) analyses play a fundamental role in gene mapping, both as a tool for fine mapping of complex trait gene and in genome-wide association studies. The use of LD analyses in practice depends crucially on the understanding of the patterns of LD in the genome. In the present study, a total of 36 SNP were selected initially in a region(More)
Osteoarthritis (OA) is a chronic degenerative joint disorder. Previous studies have shown abnormally increased apoptosis of chondrocytes in patients and animal models of OA. TNF-α and nitric oxide have been reported to induce chondrocyte ageing; however, the mechanism of chondrocyte apoptosis induced by IL-1β has remained unclear. The aim of this study is(More)
This is the first report of a novel protein from Clonorchis sinensis (C. sinensis), serine/threonine protein kinase 17A (CsSTK17A), which belongs to a member of the death-associated protein kinase (DAPK) family known to regulate diverse biological processes. The full-length sequence encoding CsSTK17A was isolated from C. sinensis adult cDNA plasmid library.(More)
BACKGROUND Abundant evidence indicates that chicken reproduction is strictly regulated by the hypothalamic-pituitary-gonad (HPG) axis, and the genes included in the HPG axis have been studied extensively. However, the question remains as to whether any other genes outside of the HPG system are involved in regulating chicken reproduction. The present study(More)
OBJECTIVE Visfatin is a newly identified proinflammatory adipocytokine whose plasma levels have been reported to be higher in subjects with type 2 diabetes mellitus. Recent studies have shown that visfatin increases the synthesis of profibrotic molecules in mesangial cells (MCs) and thus plays an important role in the pathogenesis of diabetic nephropathy.(More)
