Background: The purpose of this study was to evaluate the association among serum organochlorine pesticide residues, glutathione S-transferase M1 genetic polymorphism and female breast cancer. Methods: A 1:1 matched case-control study of 140 newly diagnosed breast cancer patients and 140 non-cancer female patients who consulted the five largest hospitals in the Tangshan city from September 2006...

Objectives: Authors aimed to investigate the association between GSTT1 and GSTM1 genetic polymorphism and susceptibility to acute myeloid leukemia (AML). Materials and methods: Genotyping polymorphisms were studied in a total adult 178 individuals (88 newly diagnosed AML patients and 90 healthy controls) using multiplex polymerase chain reaction (PCR). Results: Significant difference was report...

There were some studies on the associations between Glutathione S-transferase M1 (GSTM1) and Glutathione S-transferase T1 (GSTT1) polymorphisms and cervical cancer (CC) risk, but the results were inconsistent. Thus, a meta-analysis was performed. The electronic databases PubMed, Science Direct, CBM, and CNKI were searched for possible studies. Finally, 16 studies (1,627 cases and 2,161 controls...

Glutathione S-transferase M1 (GSTM1) might be involved in inactivation of procarcinogens that contribute to the genesis and progression of cancers. GSTM1 null status has been extensively studied as a risk factor in bladder cancer susceptibility. The aim of this study is to evaluate the role of GSTM1 null genotype in bladder cancer risk. All available studies were considered in this meta-analysi...

BACKGROUND AND OBJECTIVES Studies investigating the association between glutathione S-transferase M1 (GSTM1) gene polymorphism and laryngeal cancer risk have reported conflicting results. The aim of the present study was to conduct a meta-analysis assessing the possible associations of GSTM1 gene polymorphism with laryngeal cancer risk. METHODS The relevant studies were identified through a s...
