Glutathione S-transferases (GSTs) belong to a group of multigene detoxification enzymes, which defend cells against oxidative stress. Tannery workers are at risk of oxidative damage that is usually detoxified by GSTs. This study investigated the genotypic frequencies of GST Mu1 (GSTM1) and GST Theta1 (GSTT1) in Bangladeshi tannery workers and healthy controls followed by their status of oxidati...

The aim of this meta-analysis was to evaluate whether there was an association between glutathione S-transferase M1(GSTM1)gene polymorphism and Parkinson's disease (PD) susceptibility by pooling published data. We performed comprehensive electronic database search for articles published between February12,2015 and April30 2016. The published case-control or cohort studies related to GSTM1 gene ...

BACKGROUND Progression of systemic lupus erythematosus (SLE) could be due to oxidative stress especially through reactive oxygen species (ROS). Detoxification of ROS is largely performed by Glutathione S-transferases (GSTs), therefore polymorphisms of GSTM1, GSTT1 and GSTP1 genes which decrease enzymes activity could affect SLE susceptibility. The aim of this study was to determine the effects ...

Clinical studies have suggested that a defect in both glutathione S-transferase (GST) M1 and GSTT1 increases the risk of drug-induced hepatotoxicity. The present study developed the method that enables genotyping of GSTM1 and GSTT1 directly using a small aliquot of blood samples based on an isothermal Smart amplification process version 2 (SmartAmp-2). SmartAmp-2 reaction could complete the gen...

The genes glutathione S-transferase M1 (GSTM1) (chromosome 1p13.3) and glutathione S-transferase T1 (GSTT1) (22q11.2) code for cytosolic enzymes glutathione S-transferase (GST)-mu and GST-theta, respectively, which are involved in phase 2 metabolism. Both genes may be deleted. There is geographic and ethnic variation in genotype frequencies for both genes. In developed countries, colorectal can...

BACKGROUND Anti-tuberculosis drug induced hepatotoxicity (ATDH) is a major adverse drug reaction associated for anti-tuberculosis therapy. The glutathione S-transferases (GST) plays a crucial role in the detoxification of hepatotoxic metabolites of anti-tuberculosis drugs.An association between GSTM1/GSTT1 null mutations and increased risk of ATDH has been demonstrated in adults. Given the ethn...

BACKGROUND Published data on the association between GSTM1 and GSTT1 polymorphisms and risk of anti-tuberculosis drug-induced liver injury (ATDILI) are inconclusive. OBJECTIVE To derive a more precise estimation of the relationship, a meta-analysis on this topic was performed. DESIGN PubMed, Medline, EMBASE and Chinese national knowledge infrastructure were searched for studies on the asso...

BACKGROUND AND OBJECTIVES The GSTM1, GSTT1 and GSTP1 polymorphisms might be involved in inactivation of procarcinogens that contribute to the genesis and progression of cancers. However, studies investigating the association between GSTM1, GSTT1 or GSTP1 polymorphisms and prostate cancer (PCa) risk report conflicting results, therefore, we conducted a meta-analysis to re-examine the controversy...

GSTM1 and GSTT1 gene polymorphisms have been studied in many populations to evaluate their association with prostate cancer risk with contrasting results. The current study was aimed to find out the association of GSTM1 and GSTT1 gene polymorphisms with prostate cancer in Pakistani men. This case control study included pathologically confirmed prostate cancer patients and age matched male contr...

A major goal in molecular epidemiology is to identify preventable environmental risk factors and susceptible subpopulations. In a hospital-based molecular epidemiological case-control study of breast cancer, we investigated the relationship between DNA damage from exposure to polycyclic aromatic hydrocarbons (PAHs) and susceptibility attributable to inherited deletion of the xenobiotic detoxify...
