BACKGROUND Recent genome-wide association studies (GWAS) have mapped several novel loci influencing blood lipid levels in Caucasians. We sought to explore whether the genetic variants at newly identified lipid-associated loci were associated with CHD susceptibility in a Chinese Han population. METHODOLOGY/PRINCIPAL FINDINGS We conducted a two-stage(More)
Recent publications have found an association between variants of exostosin 2 (EXT2) gene and the risk of type 2 diabetes in some population but not in others. In an attempt to address these inconsistencies, we investigated EXT2 variants in two independent cohorts, and conducted a literature-based meta-analysis. Through regression model, we assessed the(More)
BACKGROUND Genetic architecture of coronary artery disease (CAD) is still to be defined. Since low density lipoprotein receptor-related protein 6 (LRP6) gene play critical roles in Wnt signal transduction which are important for vascular development and endodermis specification, we therefore resequenced it to search for mutations in CAD patients. METHODS(More)
MicroRNAs (miRNAs) are small regulatory RNAs that bind directly to complementary sequences on target messenger RNA (mRNA) transcripts, resulting in translational repression and/or target mRNA degradation. MiRNAs have been proven to play critical roles on the development, differentiation, and function of immune cells. Regulatory T cells (Tregs) are of(More)
Mutations in the genes low-density lipoprotein (LDL) receptor-related protein-6 (LRP6) and myocyte enhancer factor 2A (MEF2A) were reported in families with coronary artery disease (CAD). We intend to determine the mutational spectrum of these genes among hyperlipidemic and normolipidemic CAD families. Forty probands with early-onset CAD were recruited from(More)
Interferon-γ (IFN-γ) is known to enhance the immunosuppressive properties of mesenchymal stem cells (MSCs). The aim of this study was to determine whether gene modification with IFN-γ-expression plasmids could boost the therapeutic effects of MSCs on DSS-induced colitis. We first reconstructed pcDNA3.1-IFNγ plasmids, transfected them to human umbilical cord(More)
