The Sirtuin family of proteins (SIRT) encode a group of evolutionarily conserved, NAD-dependent histone deacetylases, involved in many biological pathways. SIRT1, the human homologue of the yeast Silent Information Regulator 2 (Sir2) gene, deacetylates histones, p300, p53, and the androgen receptor. Autophagy is required for the degradation of damaged(More)
OBJECTIVE Shear stress may be the most crucial local factor affecting atherogenesis. The present study investigated the effect of exposure to increased shear stress promoted by enhanced external counterpulsation (EECP) on the progression of atherosclerosis and the underlying inflammation-related molecular mechanisms in a porcine model of(More)
High altitude environments are of particular interest in the studies of local adaptation as well as their implications in physiology and clinical medicine in human. Some Chinese pig breeds, such as Tibetan pig (TBP) that is well adapted to the high altitude and Dahe pig (DHP) that dwells at the moderate altitude, provide ideal materials to study local(More)
The Tibetan cashmere goat (Capra hircus), one of the most ancient breeds in China, has historically been a critical source of meat and cashmere production for local farmers. To adapt to the high-altitude area, extremely harsh climate, and hypoxic environment that the Tibetan cashmere goat lives in, this goat has developed distinct phenotypic traits compared(More)
Dermis-derived mesenchymal stem/progenitor cells (DMS/PCs) were a multipotential stem cell population, which has potential applications in the tissue damage repair and skin transplant. Although a large number of studies deal with the human DMS/PCs self-renewal and regulation, however, the study of livestock-derived DMS/PCs has rarely been reported. Here,(More)
North Carolina design III (NCIII) is one of the most powerful and widely used mating designs for understanding the genetic basis of heterosis. However, the quantitative trait mapping (QTL) conducted in previous studies with this design was mainly based on analysis of variance (ANOVA), composite interval or multiple interval mapping methods. These(More)
As an indispensable component of the eukaryotic ribosome, ribosomal protein L23a plays an important role in protein synthesis, folding and sorting. In this study, the cDNA fragment of ribosomal protein L23a with 471 bp in size was screened from the Small Tail Han sheep ear marginal tissue cDNA expression library, it has 157 amino acids and a molecular(More)
The development of intelligent building and the network technology involved were introduced. The scheme of remote monitoring and control system of intelligent building based on LonWorks and Web was presented. The framework and working principle were analyzed. The key technology involved was studied. A prototype system was established according to the above(More)
The SIRT1 protein deacetylase is reported to have a remarkably wide spectrum of biological functions affecting such varied processes as aging, cancer, metabolism, neurodegeneration and immunity. However, the SIRT1 literature is also full of contradictions. To help establish the role(s) of SIRT1 in these and other biological processes, we set out to create a(More)
Salt tolerance in soybean [Glycine max (L.) Merr.] at the seed germination stage is a critical determinant of stable stand establishment in saline soil. This study examined one population of 184 recombinant inbred lines (RILs, F7:11) derived from a cross between Kefeng1 and Nannong1138-2 and one natural population consisting of 196 soybean landraces.
