Investigating the rate of glutathione S-transferase T1 and M1 genes deletion in patients with lung cancer
Introduction: Glutathione S-tarnsferases (GST) gene family is one of the enzymes which is responsible for detoxifying mutagens and Carcinogens chemicals. People with null genotype of GSTM1 and GSTT1 genes are at higher risk of developing cancer, especially those who are related to smoking. The goal of this study was investigating the rate of glutathione S-transferase T1 and M1 genes deletion an...
متن کاملGlutathione s-transferase M1 and T1 genetic polymorphisms in Iranian patients with glaucoma
Objective(s):Glaucoma is the second leading cause of blindness and it is related to oxidative stress based on numerous studies. Glutathione S-transferases (GSTs) are members of multigenic family, which have important role in cells as an antioxidant. In the present study, we examined the polymorphism of GSTT1 and GSTM1 deletion genotypes (T0M1, T1M0, and T0M0) in 100 Glaucoma patients (41with pr...
متن کاملGenetic Polymorphism of the Glutathione S-Transferase M1 and Development of Breast Cancer
Glutathione S-transferases (GSTs) are encoded by a superfamily of genes and play a role in the detoxification of potential carcinogens. The human GSTs are divided into four classes: alpha, mu, pi and theta. Previous studies indicated that the absence of the Glutathione S-Transferase M1 (GSTM1) protein correlated with an increased risk of developing some types of cancers. Association between spe...
متن کاملGlutathione S-transferase and N-acetyltransferase genotypes and asbestos-associated pulmonary disorders.
BACKGROUND Humans vary in their ability to metabolize endogenous and exogenous compounds. Glutathione S-transferases (GSTs) and N-acetyltransferases (NATs) are enzymes involved in the detoxification of hazardous agents. The GSTM1 and GSTT1 genes exhibit null (i.e., deletion) polymorphisms; in specific individuals, homozygous deletion (i.e., both copies lost) of these genes can be detected. Poly...
متن کاملLarynx cancer risk in relation to glutathione S-transferase M1 and T1 genotypes and tobacco smoking.
Glutathione S-transferase (GST) isoenzymes are involved in the detoxification of several tobacco smoke-derived carcinogens. It is thus conceivable that deficiency in GST activity due to homozygous deletion of the GSTM1 and GSTT1 genes (the null genotypes) may modulate susceptibility to smoking-induced cancers. The effects of the GSTM1 and GSTT1 null genotypes on laryngeal cancer risk were evalu...
