More than 500 studies have examined the association of the glutathione S-transferase M1 (GSTM1) genotype with various malignancies yielding inconsistent results. The genotyping was based on a PCR assay that identified the GSTM1 null (-/-) genotype but did not distinguish homozygous wild-type (+/+) and heterozygous (+/-) individuals. We developed an assay that allowed the definition of +/+, +/-,...

PURPOSE The glutathione S-transferases (GSTs) catalyze the glutathione conjugation of reactive electrophiles, including carcinogens and many antineoplastic drugs. GSTT1 and GSTM1 are polymorphically deleted, but the full range of genetic variation in these two genes has not yet been explored. We set out to systematically identify common polymorphisms in GSTT1 and GSTM1, followed by functional g...

The gene for glutathione-S-transferase (GST) M1 (GSTM1), a member of the GST-superfamily, is widely studied in cancer risk with regard to the homozygous deletion of the gene (GSTM1 null), leading to a lack of corresponding enzymatic activity. Many of these studies have reported inconsistent findings regarding its association with cancer risk. Therefore, we employed in silico, in vitro, and in v...

objective(s):to the best of our knowledge, this is the first report on the contributions of gst genetic variants to the risk of diabetic retinopathy in an iranian population. therefore, the objective of this study was to determine whether sequence variation in glutathione s-transferase gene (gstm1 and gstt1) is associated with development of diabetic retinopathy in type 2 diabetes mellitus (t2d...

background: acute myeloid leukemia, as most cancers, results from exposure to carcinogens and an impaired inherited individual capacity to eliminate xenobiotics. the present case-control study measures the relationship between glutathione s-transferase (gst) t1 and m1 null genotypes and the risk of acute myeloid leukemia. methods: we identified the gstt1 andgstm1 genotypes by multiplex polymera...
