Smoking is considered as the major causal factor of chronic obstructive pulmonary disease (COPD). Nevertheless, a minority of chronic heavy cigarette smokers develops COPD. This suggests important contribution of other factors such as genetic predisposing. Our objective was to investigate combined role of EPHX1, GSTP1, M1 and T1 gene polymorphisms in COPD risk, its phenotypes and lung function ...

background: endometriosis influenced by both genetic and environmental factors. associations of glutathione s-transferases (gsts) genes polymorphisms in endometriosis have been investigated by various researchers; however, the results are not consistent.objective: we examined the associations of gstm1 and gstt1 null genotypes and gstp1 313 a/g polymorphisms with endometriosis in an iranian popu...

Objetivo: describir las frecuencias alélicas y genotípicas de variantes genéticas en los genes ABCB1, CDA, DCK, GSTT1 GSTM1, involucrados el metabolismo la citarabina antraciclinas población colombiana. Materiales Métodos: analizamos ABCB1 rs1045642 (3435C>T), rs1128503 (1236G>A), rs2032582 (2677G>T/A); CDA rs2072671 (79A>C), rs532545 (-451C>T); DCK rs3771182313 (72C>T), rs230...

Background Endometriosis is one of the most commonly encountered benign problems in gynaecology. It is frequently associated with chronic pelvic pain, dysmenorrhoea, menorrhagia and dyspareunia, which lead to infertility. We determined the possible association between CYP1A1 MspI and GSTM1 null polymorphism in the pathogenesis of endometriosis. MaterialsAndMethods Ninety seven cases of endometr...

BACKGROUND GST is a family of enzymes that are important in protection of the body against oxidative stress. OBJECTIVES Investigate the association between GSTT1 and GSTM1 polymorphism and hypertension. MATERIALS AND METHODS GSTT1 and GSTM1 genotypes were detected by PCR. The fragments were then analyzed by agarose gel electrophoresis. RESULTS There is no significant association between G...

To evaluate interactions between lifestyle factors and glutathione-S-transferases M1 (GSTM1) and GSTT1 genotypes with reference to development of esophageal and stomach cancers, we conducted a case-control study of 141 cases of esophageal cancer, 153 cases of stomach cancer and 223 population-based controls in Huaian City of Jiangsu Province, China. GSTM1 and GSTT1 genotypes were identified by ...

Background: Glutathione S-transferase M1 (GSTM1) is involved in the detoxification of carcinogenic agents. DNA copy number variants of GSTM1 may be associated with cancer progression and may result in reduced survival time of various cancers. Determination of DNA copy number variants was here used to assess the association between GSTM1 copy number variant and pathological status and survival t...

Glutathione S-transferases (GSTs) conjugate activated xenobiotics with glutathione; thus, GST induction may improve detoxification and excretion of potentially harmful compounds. Using a randomized cross-over design, we tested the hypothesis that, in humans, serum GST-alpha concentration (GST-alpha) and GST activity increase with vegetable consumption and that this effect is GSTM1 genotype depe...
