AIMS To investigate the possible interaction between occupational risk factors and genotype for glutathione S-transferases M1 and T1 (GSTM1 and GSTT1) in renal cell cancer (RCC). METHODS One hundred patients with RCC and 200 outpatient controls were enrolled at Parma University Hospital. The polymorphisms of glutathione S-transferase M1-1 (GSTM1) and T1-1 (GSTT1) were investigated by PCR; occ...

UNLABELLED Gene variability related to carcinogen activation and detoxification may interfere with susceptibility to head and neck cancer. AIM To investigate the relation between GSTT1 and GSTM1 null polymorphisms and the risk of head and neck squamous cell carcinoma in cigarette smokers. MATERIAL AND METHOD A case-control study conducted at the Sao Jose do Rio Preto Medical School, Brazil....

PURPOSE to investigate genetic polymorphisms in GSTM1, GSTT1 and CYP1A1 and the association with the risk of oral cancer in the Jakarta population. METHOD A total of 81 cases and 162 controls matched for age and sex were selected from 5 hospitals in Jakarta. Sociodemographic data using questionnaires were obtained and peripheral blood samples were collected with informed consent for PCR-RFLP ...

Associations of GSTT1, GSTM1 and CYP1A1 gene variants with risk of developing oral cancer were evaluated in this study. A case-control study was conducted in Pashtun population of Khyber Pakhtunkhwa province of Pakistan in which 200 hospital based oral cancer cases and 151 population based healthy controls exposed to similar environmental conditions were included. Sociodemographic data were obt...

BACKGROUND Mercury (Hg) is toxic to both the reproductive and nervous systems. In addition, glutathione S-transferases (GSTs), which conjugate glutathione to a variety of electrophilic compounds, are involved in the detoxification of Hg. OBJECTIVE In this study we examined the association between prenatal exposure to Hg and birth weight as well as the influence of GST polymorphisms. METHODS...

Chloroform accumulation in the body and increase its steady-state concentrations blood of exposed people have been established to be associated with polymorphisms enzyme genes a genotype involved metabolism water disinfection byproducts (A415G EPHX1 gene, C1091T CYP2E1 zero mutations GSTT1 GSTM1 genes) (р < 0.000001). These correlate higher chloroform levels consuming chlorinated drinking wa...

Glutathione S-transferase (GST) enzymes protect cells against xenobiotics and oxidative stress products through an electrophilic conjugation process. We investigated the theta (GSTT1) and mu (GSTM1) null genotypes in a group of leukopenic subjects and normal subjects from Northeast Brazil, evaluating their use as biomarkers of susceptibility for developing leukopenia. In a sample-based case-con...

One of the most frequently observed causes of blindness in infancy is the pathogenesis known as retinopathy of prematurity (ROP). Angiotensin-converting enzyme (ACE) is a vital enzyme in the renin-angiotensin-aldosterone system; it is involved in the development of cardiovascular system diseases linked to I/D polymorphism of the ACE gene. Glutathione-S-transferase enzyme (GST) is one of the mos...

OBJECTIVE Previous studies investigating the relationship between glutathione S-transferase T1 (GSTT1) gene deletion polymorphism and lung cancer risk among Chinese population produced inconsistent results. To obtain a precise conclusion, we performed this meta-analysis to evaluate the association between GSTT1 deletion polymorphism and lung cancer risk among Chinese population. METHODS The d...
