PURPOSE To investigate the association of glutathione S-transferase (GST) GSTM1, GSTT1, and GSTP1 genes with the risk of primary open angle glaucoma (POAG) and clinical features of the disease. METHODS We conducted a case-control study that included 87 Brazilian patients with POAG and 85 healthy controls matched for age, ethnicity, and sex, whose blood samples were genotyped for polymorphisms...
PURPOSE The aim of this study was to evaluate any association of GSTM1 and GSTT1 null genotypes with the risk of lung cancer in a South Korean population. METHODS We conducted a large-scale, population-based case-control study including 3,933 lung cancer cases and 1,699 controls. Genotypes of GSTM1 and GSTT1 were determined using real-time polymerase chain reaction. RESULTS In logistic regr...
BACKGROUND AND PURPOSE Heterogeneity in patient' s response to chemotherapy is consistently observed across populations. Pharmacogenomics, the study of inherited differences in drug disposition and effects, is emerging as a tool to predict efficacy and toxicity of drugs. Glutathione S-transferases (GST) are involved in the metabolism and detoxification of environmental carcinogens and some clas...
Introduction Long-term differences in steroid hormone levels between women likely contribute to the interindividual variation in ovarian cancer risk, although the precise biological mechanisms are unclear (1). The P450c17a (CYP17) gene codes for 17ahydroxylase and 17,20 lyase which catalyze the rate-limiting step in androgen biosynthesis, cleaving the C21 steroids to the C19 steroids, androsten...
The aryl hydrocarbon receptor (encoded by the Ahr locus) is a ligand-activated transcription factor that mediates the toxicology and teratology of 2,3,7,8-tetrachlorodibenzo-p-dioxin (dioxin). In an effort to understand the role of the maternal compartment in dioxin teratology, we designed a breeding strategy that allowed us to compare the teratogenic response in embryos from Ahr(-/-) (null) an...
