GSTT1 and M1 polymorphisms in Hürthle thyroid cancer patients
چکیده انگلیسی

Glutathione S-transferases (GST) are an important part of cell defense against numerous genotoxic compounds and ROS. In order to test the possibility of association between the GSTT1 and M1 null allele variant, and the risk of TCO (thyroid carcinoma with cell oxyphilia), a case-control study was carried out. The rationale for our study was that according to the important roles of GST enzymes in cells and association of GST null genotypes with many types of tumors, inactivating polymorphisms may be genetic susceptibility factors in the etiology of oxyphilic thyroid tumors characterized by mitochondrial dysfunction, increased ROS production and resistance to chemio- and radio-therapy. We found the frequency of GSTT1 null genotype of 19.2% in cases and 15.7% in controls, with an adjusted odds ratio (OR) of 1.4 (95% confidence interval (CI), 0.70–2.81), and a frequency of GSTM1 null genotype of 59% in cases with oxyphilic tumors and of 55.6% in controls (OR 1.24; 95% CI, 0.62–2.48), indicating that the GSTT1 and M1 null genotypes do not increase the risk of development of oxyphilic tumors.
