OBJECTIVE To identify the susceptibility genes of type 2 diabetes in Chinese Han population. METHODS Single nucleotide polymorphism (SNP) discovery, genotyping and haplotype construction were performed in 30 candidate genes. Case-control study were carried out in a population-based sample and confirmed by the transmission disequilibrium test (TDT)(More)
Artesunate (ART), a semi-synthetic derivative of artemisinin isolated from the traditional Chinese herb Artemisia annua, is an effective novel antimalarial drug. The present study investigated the apoptotic activity of artesunate in cultured human umbilical vein endothelial cell (HUVEC) by means of nuclear staining, DNA agarose gel electrophoresis, and flow(More)
Artesunate (ART) is a semi-synthetic derivative of artemisinin extracted from the plant Artemisia annua is a safe and effective antimalarial drug. In the present investigation, ART was found also to inhibit angiogenesis in vivo and in vitro. The anti-angiogenic effect in vivo was evaluated in nude mice by means of human ovarian cancer HO-8910 implantation(More)
Dihydroartemisinin, a more water-soluble metabolite of artemisinin derivatives, is a safe and most effective antimalarial analog of artemisinin. In the present study, we investigated the antiangiogenic activity of dihydroartemisinin in vitro and in vivo, and investigated dihydroartemisinin-induced apoptosis in human umbilical vein endothelial cells (HUVEC).(More)
Artesunate (ART), a semi-synthetic derivative of artemisinin extracted from the Chinese herb Artemisia annua, is a safe and effective antimalarial drug. In the present investigation, we analyzed the inhibitory effects of ART on angiogenesis and on VEGF production in chronic myeloid leukemia (CML) K562 cells in vitro and in vivo. In order to analyze the(More)
OBJECTIVE To probe the candidate susceptibility gene (s) of type 2 diabetes in the formal mapping region, 1p36.33-p36.23, in Han people of Northern China using single nucleotide polymorphisms (SNPs). METHODS 23 SNPs located in 10 candidate genes in the mapping region were chosen from public SNP domain by bioinformatic methods and single base extension(More)
AIM To identify the susceptible gene (s) for type 2 diabetes in the previously mapped region, 1p36.33-p36.23, in Han population of North China using single nucleotide polymorphisms (SNPs) and to analyze the haplotypes of the gene (s) related to type 2 diabetes. METHODS Twenty three SNPs located in 10 candidate genes in the mapped region were chosen from(More)
OBJECTIVE To search for the susceptibility variant (s) of type 2 diabetes in the susceptible regions on chr.1 (1p36.23-36.33, 1q24.3-25.1, and 1q42.12-42.13) by genotyping SNP markers in case-control DNA samples and identifying the haplotype associated with type 2 diabetes. METHODS Totally 124 SNPs in 33 candidate genes in the mapped regions were chosen(More)
OBJECTIVE To study the function of 5 single nucleotide polymorphisms (SNPs) of the PRKCZ gene, a susceptibility gene for type 2 diabetes in Han population of North China, in the pathogenesis of the disease. METHODS Bioinformatic methods and reporter gene activity determination were used to analyze the function of the 5 SNPs. RESULTS The reporter gene(More)
