Glutathione S-transferases (GSTs) are major intracellular antioxidants, which, impaired in their function, are involved in the progress of schizophrenia (SCZ). The aim of this case-control study was to investigate the association between the polymorphism of glutathione S-transferases M1 (GSTM1), T1 (GSTT1), the glutathione S-transferase P1 gene (GSTP1) and SCZ. We isolated genomic DNA from peripheral blood of 93 individuals with SCZ and 99 healthy control subjects' genotypes analyzing them for GSTM1, GSTT1 and GSTP1 using polymerase chain reaction. The analysis of the gene–gene interaction between GSTs indicated that the magnitude of the association was greater for the combined AG/GSTT1 & GSTM1 genotypes (OR = 2.51; 95% CI: 1.13–5.63, P = 0.02). The AG and combined AG + GG genotypes of GSTP1 increased the risk of SCZ (OR = 1.83; 95% CI: 0.94–3.75 and OR = 1.71; 95% CI: 0.92–3.19, respectively). The genotypes of GSTT/NULL, NULL/GSTM and NULL/NULL increased the risk of SCZ (OR = 2.05; 95% CI: 0.9–4.74; OR = 2.0; 95% CI: 1.68–2.31; and OR = 1.8; 95% CI: 0.57–2.46, respectively). The present study supports previous data that suggest that impairment in the function of GSTs genes may increase the risk of SCZ.

Glutathione S-transferases (GSTs) have been associated with outcome in human cancers treated with cytotoxic chemotherapy. In a case-control study, we investigated the association between polymorphisms within theGSTM1, GSTT1, and GSTP1 genes and risk of relapse in childhood acute lymphoblastic leukemia (ALL). Cases were relapsed patients. Controls were successfully treated patients with a minimum follow-up of 5 years. The null genotype (absence of both alleles) for GSTM1 or GSTT1 conferred a 2-fold (OR = 0.5, 95% CI = 0.23-1.07, P = .078) and 2.8-fold (OR = 0.36, 95% CI = 0.13-0.99, P = .048) reduction in risk of relapse, respectively, relative to the presence of the GSTM1 or GSTT1 gene. The GSTP1Val105/Val105 genotype showed a 3-fold decrease in risk of relapse (OR = 0.33, 95% CI = 0.09-1.23,P = .099) in comparison to the combined category of Ile105/Val105 and Ile105/Ile105 genotypes. No particular associations with relapse were observed for the GSTP1polymorphism at codon 114. The risk of relapse when having 1 of the low-risk genotypes (GSTM1 null, GSTT1 null,GSTP1 Val105/Val105) decreased 1.9-fold (OR = 0.53, 95% CI = 0.24-1.19, P = .123), and the risk when having 2 or 3 low-risk genotypes 3.5-fold (OR = 0.29, 95% CI = 0.06-1.37, P = .118), compared with individuals having no low-risk genotype (P for trend = .005). Our results suggest that polymorphisms within genes of the GST superfamily may be associated with risk of relapse in childhood ALL.

AbstractCruciferous vegetables contain high levels of glucosinolates (GSL) and isothiocyanates (ITC). ITC are known to induce glutathione S-transferases (GST) and thus exert their anticarcinogenic effects. This study explored the combined effects of cruciferous vegetable, GSL and ITC intake and GST polymorphisms on breast cancer risk. A total of 737 breast cancer cases and 756 controls were recruited into this case–control study. OR and 95 % CI were assessed by multivariable logistic regression. Higher cruciferous vegetable, GSL and ITC intakes were inversely associated with breast cancer risk, with adjusted OR of 0·48 (95 % CI 0·35, 0·65), 0·54 (95 % CI 0·40, 0·74) and 0·62 (95 % CI 0·45, 0·84), respectively. Compared with women carrying the GSTP1 rs1695 wild AA genotype and high cruciferous vegetable, GSL or ITC intake, carriers of the AA genotype with low cruciferous vegetable, GSL and ITC intake had greater risk of breast cancer, with adjusted OR of 1·43 (95 % CI 1·01, 1·87), 1·34 (95 % CI 1·02, 1·75) and 1·37 (95 % CI 1·05, 1·80), respectively. Persons with the GSTM1-null genotype and lower intake of cruciferous vegetables, GSL and ITC had higher risk of breast cancer than those with the GSTM1-present genotype and higher intake, with OR of 1·42 (95 % CI 1·04, 1·95), 1·43 (95 % CI 1·05, 1·96) and 1·45 (95 % CI 1·06, 1·98), respectively. Among women possessing the GSTT1-present genotype, low intake of cruciferous vegetables, GSL or ITC was associated with higher risk of breast cancer. But these interactions were non-significant. This study indicated that there were no significant interactions between cruciferous vegetable, GSL or ITC intake and GST polymorphisms on breast cancer risk.
