In the BC group, NMP22 (p = 0.005) concentration, GST-π (p = 0.003) in urine and GST (p = 0.009) activity in blood were statistically significantly higher than in the healthy controls.
We aimed to investigate bladder cancer risk with reference to polymorphic variants of cytochrome p450 (CYP) 1A1, CYP1B1, glutathione S-transferase (GST) M1, and GSTT1 genes in a case control study.
Although polymorphisms in glutathione S-transferase (GST) have been associated with the risk of bladder cancer (BC) development, few reports provide information about the prognosis of BC.
The lower most GST enzyme concentration was reported in patients with bilharzial bladder cancer (26 +/- 4.4 ng/ml) with significant difference between it and that of the second group (36.8 +/- 4.1 ng/ml, P < 0.05) and that of the controls (40.4 +/- 4 ng/ml, P < 0.005).
Although polymorphisms in glutathione S-transferase (GST) have been associated with the risk of bladder cancer (BC), few reports provide information about the development of BC.
To explore the association of polymorphisms in N-acetyltransferase 2 (NAT2), glutathione S-transferase (GST), cytochrome P450 (CYP) 2A6, and CYP 2A13 genes with susceptibility and clinicopathologic characteristics of bladder cancer in a Chinese population.
The associations between the genotypes of glutathione S-transferase (GST) M1, GSTP1, GSTT1 and N-acetyltransferase (NAT) 1 and the phenotypes of NAT2 and cytochrome P450 (CYP) 1A2 and bladder cancer risk were examined in a case-control study involving 731 bladder cancer patients and 740 control subjects in Los Angeles County, California.
We investigated the role of glutathione S-transferase (GST) enzymes (M1, T1), methylenetetrahydrofolate (MTHFR) 677 and 1298, and the NAD(P)H:quinone oxidoreductase (NQO1) polymorphisms in a population-based bladder cancer case-control study in Argentina.
Bladder cancer is associated with smoking, occupational exposures, and glutathione S-transferase (GST) M1 and N-acetyltransferase (NAT) 2 polymorphisms that may influence carcinogen metabolism, but somatic p53mutations are often CpG dinucleotide G:C-A:T transitions that can occur spontaneously.
To study whether specific or bulk hypermethylation predicts intrabladder recurrence, we determined the frequency of aberrant promoter hypermethylation of seven genes, hMLH1, O(6)-methylguanine-DNA-methyltransferase (MGMT), p16, Von Hippel-Lindau (VHL), death-associated protein kinase (DAP-kinase), glutathione S-transferase P1 (GST-P1) and E-cadherin in 55 superficial bladder cancers and 5 normal urothelial epithelia by methylation-specific PCR (MSP).
A combined analysis of two polymorphic enzymes, glutathione S-transferase mu (GST M1) and q (GST T1) and their implication as cancer risk factors was performed in a case-control study of lung and bladder cancers.
Defective glutathione S-transferase (GST) and N-acetyltransferase (NAT) enzymes have been associated with an increased risk of developing lung and bladder cancer.
