In order to further evaluate the relationship between the variations of CAPN1 gene and meat tenderness, the CAPN1 genomic sequences were cloned and sequenced, its CDS was analyzed with PCR-SSCP, and the genotype analyses covered 109 individuals from Wild boar, Min pig and Yorkshire. Fifteen of total 21 introns were cloned. Five pairs polymorphic primers for(More)
Subgroup A, B, and J ALVs are the most prevalent avian leukosis virus (ALV). Our study attempted to develop two SYBR Green I-based real-time PCR (RT-PCR) assays for specific detection of ALV subgroup J (ALV-J) and multiplex detection of ALV subgroups A and B (ALV-A/B), respectively. The two assays showed high specificity for ALV-J and ALV-A/B and the(More)
The Toll-like receptor 5 (TLR5) recognizes flagellin of Gram-positive and -negative bacteria and plays an important role in the host defense system. Here, we surveyed single nucleotide polymorphisms (SNPs) in the coding sequence of the porcine TLR5 gene in 83 individuals from five pig breeds, these including Chinese local populations and Western commercial(More)
A proteomics approach was used to reveal the up-regulated proteins involved in the targeted mitogen-activated protein kinase (MAPK) signal transduction pathway in DF-1 cells after ALV subgroup J (ALV-J) infection. Next, we found that ALV-J CHN06 strain infection of DF-1 cells correlated with extracellular signal-regulated kinase 2 (ERK2) activation, which(More)
BACKGROUND Porcine oocytes were sensitive to cooling because of the presence of excessive lipids. OBJECTIVE To evaluate the effect of lipid removal on the mitochondrial distribution, the formation of reactive oxygen species (ROS) and the viability of porcine oocytes after vitrification. MATERIALS AND METHODS Porcine oocytes were cultured in vitro, and(More)
UNLABELLED The integration of retroviruses into the host genome following nonrandom genome-wide patterns may lead to the deregulation of gene expression and oncogene activation near the integration sites. Slow-transforming retroviruses have been widely used to perform genetic screens for the identification of genes involved in cancer. To investigate the(More)
PCR-RFLP was applied to analyze the polymorphism of MSTN gene UTR in 345 sheep that comprised of eleven sheep breeds, namely Texel sheep, Charolais sheep, Small-tailed Han sheep, Monggolian sheep, Ujumqin sheep, Altay Fat-rumped sheep, Hulunbeir sheep, Tashikurgan sheep, Duolang sheep, Hu sheep, and Gangba sheep. A 271 bp and a 1 003 bp long PCR products(More)
Subgroup J avian leukosis virus (ALV-J) is an oncogenic retrovirus that causes immunosuppression and enhances susceptibility to secondary infection. The innate immune system is the first line of defense in preventing bacterial and viral infections, and dendritic cells (DCs) play important roles in innate immunity. Because bone marrow is an organ that is(More)
The in vitro maturation (IVM) efficiency of porcine embryos is still low because of poor oocyte quality. Although brilliant cresyl blue positive (BCB+) oocytes with low glucose-6-phosphate dehydrogenase (G6PDH) activity have shown superior quality than BCB negative (-) oocytes with high G6PDH activity, the use of a BCB staining test before IVM is still(More)
Previous research on Corynebacterium glutamicum revealed that 3-deoxy-d-arabino-heptulosonate 7-phosphate synthase (DSCg, formerly DS2098) interacts with chorismate mutase (CMCg, formerly CM0819). In this study, we investigated the interaction by means of structure-guided mutation and enzymatic assays. Our results show that the interaction imparted a new(More)
