Endometriosis is a gynecologic pathology with a high prevalence and unknown etiology. Therefore, an increasing number of studies has been undertaken to search for associations between endometriosis and alterations or polymorphisms in candidate genes, including glutathione S-transferase mu 1 (GSTM1) and glutathione S-transferase theta 1 (GSTT1). We analyzed the frequency of present/absent polymo...

glutathione s-transferases (gsts; ec: 2.5.1.18) are ubiquitous multifunctional enzymes, which play a key role in cellular detoxification. functional genetic polymorphisms in genes encoding gstm1 (a member of gst class mu; omim: 138350), and gstt1 (a member of gst class theta; omim: 600436) have been well defined. the functional null alleles of gstm1 and gstt1 represent deletions of gstm1 and gs...

Amaç: Çalışmamızın amacı, KOAH hastalığının oluşumunda GSTM1 ve GSTT1 gen bölgesindeki “null” allellerinin rolü olup olmadığını araştırmaktır.

Exposure to benzene has been associated with haematological diseases such as neutropenia (NEB) and acute myeloid leukaemia (AML). We tested whether the null genotypes of the GSTM1 and GSTT1 genes, involved in benzene inactivation, altered the risk for NEB in southeastern Brazil. Genomic DNA from 55 NEB patients and 330 controls was analysed by multiplex-polymerase chain reaction. The frequency ...

Endometriosis is one of the most frequent benign gynecological disorders. Numerous studies have shown an association between GSTM1 and/or GSTT1 polymorphisms and endometriosis susceptibility. However, these associations remain inconclusive. To derive a more precise estimation, we conducted a comprehensive search to identify all existing studies and then performed a meta-analysis. Electronic lit...

Polymorphisms of glutathione S-transferase (GST) proteins are correlated with elevated risk of many cancers including hematologic malignancies. Particularly concerning acute promyelocytic leukemia (APL), the studies on association between GSTM1, GSTT1 and GSTP1 and the disease predisposition are scarce and contradictory. The aim of this study was to examine whether polymorphic variations in GST...

Oxidative stress is associated with osteoporosis. The glutathione S-transferases form the major detoxifying group of enzymes responsible for eliminating products of oxidative stress. We have therefore proposed GSTM1 and GSTT1 genes as candidates for studying the genetics of osteoporosis. The aim of the present study was to examine possible association of GSTM1 and GSTT1 gene deletion polymorphi...

BACKGROUND Due to the possible involvement of Glutathione S-transferase Mu-1 (GSTM1) and Glutathione S-transferase theta-1 (GSTT1) in the detoxification of environmental carcinogens, environmental toxins, and oxidative stress products, genetic polymorphisms of these two genes may play important roles in the susceptibility of human being to hepatocellular carcinoma. However, the existing researc...
