- Abstract
Introduction: Glutathione S-transferases have been implicated in the development of bladder cancer (BC). We investigated the genotype and expression of glutathione S-transferase-mu (GSTM1) and glutathione S-transferase-theta (GSTT1) in BC tissue specimens. Materials and Methods: Tumor samples and matched normal mucosae were obtained from 34 patients. Genomic DNA was used to analyze GSTM1 and GSTT1 genotypes using multiplex polymerase chain reaction. GSTM1 and GSTT1 mRNA levels were measured using real-time reverse transcriptase polymerase chain reaction. Results:GSTM1 mRNA expression was lower in tumor tissues than in matched normal bladder mucosae, whereas GSTT1 mRNA expression was significantly higher. GSTT1 mRNA expression was higher in muscle-invasive BC and high-grade cancers than in non-muscle-invasive BC and lower-grade tumors. Conclusions:GSTT1 is correlated with characteristics of aggressive BC. GSTT1 may play an important role in tumorigenesis and disease progression in patients with BC. Copyright © 2010 S.
