BACKGROUND Individual variability in arsenic metabolism may underlie individual susceptibility toward arsenic-induced skin lesions and skin cancer. Metabolism of arsenic proceeds through sequential reduction and oxidative methylation being mediated by the following genes: purine nucleoside phosphorylase (PNP), arsenic (+3) methyltransferase (As3MT), glutathione S-transferase omega 1 (GSTO1), an...
رد حاد پیوند کلیه یک خطر جدی برای ماندگاری بافت پیوندی در مدت بعد از عمل پیوند است که می تواند علاوه بر تاثیر در اختلال عملکرد بافت? در از دست دادن بافت نیز موثر می باشد. خانواده گلوتاتیون s ترانسفرازها یکی از آنزیم های مهم برای سم زدایی مواد زنوبیوتیک همچون داروهای مهارکننده سیستم ایمنی می باشد. کلاس جدید این خانواده? کلاس امگا با دو ژنgsto1 و gsto2است که ویژگی های منحصر به فرد از جمله وجود اس...
cyclosporine a (csa), a cyclic polypeptide metabolite extracted from the fungus, is used clinically to combat organ graft rejection in transplant subjects. previous studies have shown that csa exposure enhances the production of reactive oxygen species (ros) and lipid peroxidation, which are directly involved in csa toxicity. to protect cells and organs against ros, the human body has evolved a...
Over the last two decades, significant data has been accumulated linking Glutatione S-Transferases (GSTs) with the development of several diseases. Contemporary studies have demonstrated the impact of ethnicity on GST allele frequencies. The aim is to verify if the variability of GST genes reflects population demographic history or rather selective pressures. GST genes (GSTM1, GSTO1 GSTO2, GSTT...
We previously reported genetic linkage of loci controlling age-at-onset in Alzheimer disease (AD) and Parkinson's disease (PD) to a 15 cM region on chromosome 10q. Given the large number of genes in this initial starting region, we applied the process of 'genomic convergence' to prioritize and reduce the number of candidate genes for further analysis. As our second convergence factor we perform...
We previously reported a linkage region on chromosome 10q for age-at-onset (AAO) of Alzheimer (AD) and Parkinson (PD) diseases. Glutathione S-transferase, omega-1 (GSTO1) and the adjacent gene GSTO2, located in this linkage region, were then reported to associate with AAO of AD and PD. To examine whether GSTO1 and GSTO2 (hereafter referred to as GSTO1h) are responsible for the linkage evidence,...
Cyclosporine A (CsA), a cyclic polypeptide metabolite extracted from the fungus, is used clinically to combat organ graft rejection in transplant subjects. Previous studies have shown that CsA exposure enhances the production of reactive oxygen species (ROS) and lipid peroxidation, which are directly involved in CsA toxicity. To protect cells and organs against ROS, the human body has evolved a...
Chronic obstructive pulmonary disease (COPD) is a strong risk factor for lung cancer. Published studies about variations of genes encoding glutathione metabolism, DNA repair, and inflammatory response pathways in susceptibility to COPD were inconclusive. We evaluated 470 single-nucleotide polymorphisms (SNP) from 56 genes of these three pathways in 620 cases and 893 controls to identify suscept...
Arsenic is associated with bladder cancer risk even at low exposure levels. Genetic variation in enzymes involved in xenobiotic and arsenic metabolism may modulate individual susceptibility to arsenic-related bladder cancer. Through a population-based case-control study in NH (832 cases and 1191 controls), we investigated gene-environment interactions between arsenic metabolic gene polymorphism...
PURPOSE To examine the differences in urinary arsenic metabolism patterns in men affected by occupational exposure, we performed a study on 149 participants—workers of a copper mill and 52 healthy controls without occupational exposure. To elucidate the role of genetic factors in arsenic (As) metabolism, we studied the associations of six polymorphisms: As3MT Met287Thr (T>C) in exon 9; As3MT A>...
