Most cashmere goats are found in northern China and Mongolia. They are regarded as precious resources for their production of high quality natural fibre for the textile industry. It was the first time that the genetic diversity and population structure of nine Chinese cashmere populations has been assessed using 14 ISAG/FAO microsatellite markers. In(More)
Available abundant genomic data allows us to study the evolution of the yeast genome at a fine scale. In this study, we examined the adaptive evolution of coding and promoter regions in three Saccharomyces cerevisiae strains. First, using a maximum-likelihood approach, we identified 76 positively selected genes (PSG) whose coding regions likely have(More)
Amniotic epithelial cells (AECs) express Oct4, Nanog and Sox-2, which are necessary for maintaining the undifferentiated state of pluripotent stem cells. AECs additionally express CK19, which is a specific marker of epithelial cells, both in vivo and in vitro. In this research, we investigated the biological characteristics and potential for cell therapy of(More)
A high-density cell culture method to produce human angiostatin has been successfully established by constitutive expression of the protein in Pichia pastoris. The fermentation was carried out in a 20 l bioreactor with a 10 l working volume, using a high-density cell culture method by continuously feeding with 50% glycerol-0.8% PTM4 to the growing culture(More)
We determined the genetic diversity and evolutionary relationships among 26 Chinese indigenous horse breeds and two introduced horse breeds by genotyping these animals for 27 microsatellite loci. The 26 Chinese horse breeds come from 12 different provinces. Two introduced horse breeds were the Mongolia B Horse from Mongolia and the Thoroughbred Horse from(More)
The genetic consequences of population differentiation and isolation have been the subject of conservation biology. In this study, we analysed the genetic diversity and structure of Mongolian sheep in China. These animals belong to a traditional local breed with high production, extensive adaption, early maturity and roughage resistance. For this purpose,(More)
The product of the OTUB1 gene is a member of the OTU superfamily of predicted cysteine proteases and inhibits cytokine gene transcription via its interaction with a ubiquitin protease and E3 ubiquitin ligase. To further understand the functions of the porcine OTUB1 gene, the subcellular localization of porcine OTUB1 protein was analyzed. We first cloned a(More)
It is generally believed that domestic sheep have two maternal lineages (haplotypes A and B), based on mitochondrial DNA analysis. In the present study, we provide evidence that a novel maternal lineage (haplotype C) is exhibited in Chinese native sheep. To verify this finding, 231 samples were collected from six Chinese local breeds, which cover the vast(More)
Mesenchymal stem cells (MSCs), with their capacity for self-renewal and differentiation into various cell types, are important seed cells for stem cell therapy. MSCs exhibit potent pathotropic migratory properties that make them attractive for use in tumor prevention and therapy. However, little is known about the underlying molecular mechanisms that link(More)
In March 2013, an influenza outbreak caused by the novel avian-origin H7N9 influenza A virus emerged in eastern China and had caused 43 fatalities by 31 July 2013, although the basis for disease pathogenesis still remains unclear. To assess the immunological and viral factors associated with disease severity, viral RNA and inflammatory cytokines were(More)
