We have developed a robust microarray genotyping chip that will help advance studies in genetic epidemiology. In population-based genetic association studies of complex disease, there could be hidden genetic substructure in the study populations, resulting in false-positive associations. Such population stratification may confound efforts to identify true(More)
Oxidative stress has been implicated in all stages of atherosclerosis, but how inherited variations in oxidative stress genes influence the severity of cardiovascular disease is not known. We tested associations between polymorphisms in candidate oxidative stress genes, plasma oxidative stress biomarkers, and cardiovascular mortality in an angiography(More)
Protamine genes play important roles in DNA packaging within the sperm nucleus. In order to evaluate the association of PRM1, PRM2, KIT and KITLG variants with susceptibility to severely defective spermatogenesis, 309 male infertility patients (199 cases with non-obstructive azoospermia and 110 cases with severe oligozoospermia) and 377 controls were(More)
PURPOSE To investigate associations between genetic variants involved in microRNA networks (microRNA biogenesis, microRNA and microRNA binding sites) and risk of gastric cancer. METHODS We genotyped 19 SNPs of the microRNA-related genes in a case-control study of 311 gastric cancers and 425 cancer-free controls in a Chinese Han population. RESULTS We(More)
BACKGROUND Given the complex nature of the responses that can occur in host-pathogen interactions, dual transcriptomics offers a powerful method of elucidating these interactions during infection. The gene expression patterns of Aspergillus fumigatus conidia or host cells have been reported in a number of previous studies, but each focused on only one of(More)
BACKGROUND Arrayed primer extension (APEX) is a microarray-based rapid minisequencing methodology that may have utility in 'personalized medicine' applications that involve genetic diagnostics of single nucleotide polymorphisms (SNPs). However, to date there have been few reports that objectively evaluate the assay completion rate, call rate and accuracy of(More)
Scientific literature describing arrayed primer extension and other array-based minisequencing technologies consistently cite the requirement for four fluorescent dideoxynucleotides (with concomitant absence/inactivation of deoxynucleotides) to ensure single-base extension and thus sequence-specific intensity data that can be interpreted as a base call or(More)
OBJECTIVES To study the dental fluorosis and caries in the permanent teeth of 12 to 13-year-old children in fluorosis-endemic areas; to assess the relationship between fluorosis and the fluoride content of the drinking water and the relationship between caries and the fluoride content of the water; finally, to analyze the effect of fluoride intake and water(More)
Oxidative stress is believed to play an important role in the pathogenesis of smoking-induced chronic obstructive pulmonary disease. We hypothesized that polymorphisms of antioxidant genes glutathione S-transferase M1 (GSTM1), GSTT1, GSTP1, and heme oxygenase-1 (HMOX1) would be associated with susceptibility to accelerated decline of lung function in(More)
Abciximab, a derivative of the murine mAb 7E3, protects against ischemic complications of percutaneous coronary interventions by inhibiting ligand binding to the alphaIIbbeta3 receptor. In this study we identified regions on integrin beta3 that control 7E3 binding. Murine/human amino acid substitutions were created in two regions of the betaA domain that(More)
