BACKGROUND Increased oxidative stress is a hallmark of end-stage renal disease (ESRD). Glutathione S-transferases (GST) are involved in the detoxification of xenobiotics and protection of oxidative damage. We hypothesized that genetic polymorphism in antioxidant enzymes GSTA1, GSTM1, GSTP1 and GSTT1 is more frequent in ESRD and modulates the degree of(More)
OBJECTIVE We investigated the role of the glutathione S-transferase A1, M1, P1 and T1 gene polymorphisms and potential effect modification by occupational exposure to different chemicals in Serbian bladder cancer male patients. PATIENTS AND METHODS A hospital-based case-control study of bladder cancer in men comprised 143 histologically confirmed cases(More)
PURPOSE To get more insight into molecular mechanisms underlying oxidative stress and its role in different types of seizure, in this study, oxidative byproducts of proteins, lipids and DNA, as well as, antioxidant enzyme activities were studied in adult patients with epilepsy. METHODS Study was performed in 60 patients with epilepsy and in 25 healthy(More)
BACKGROUND Although the majority of previous findings unequivocally confirmed the existence of systemic oxidative stress in chronic heart failure (CHF) patients, data on prognostic potential of biomarkers of oxidative lipid and protein damage are limited. We aimed to address the relation of oxidative stress markers to severity and prognosis in CHF secondary(More)
OBJECTIVES To examine the association between gene variants of the detoxifying and antioxidant enzymes glutathione transferase M1 (GSTM1) and glutathione transferase A1 (GSTA1) and the extent of oxidative damage in patients with transitional cell carcinoma (TCC) of the urinary bladder. METHODS GSTM1 deletion polymorphism was identified by polymerase chain(More)
OBJECTIVES Glutathione S-transferases (GSTs) are a family of enzymes involved in detoxification. Genes encoding for GSTA1, GSTM1, GSTP1, and GSTT1 proteins are polymorphic, which can result in complete or partial loss of enzyme activity. Previous studies have associated polymorphisms of GSTA1, GSTM1, and GSTP1 genes with a higher risk of bladder cancer, but(More)
BACKGROUND To assess the prognostic significance of four inflammatory markers (TNF-α, high sensitive C-reactive protein (hs-CRP), intercellular cell adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1)) in chronic heart failure (CHF) patients with respect to individual outcomes, especially disease exacerbation and mortality. METHODS(More)
OBJECTIVE Although C-reactive protein (CRP) is among the best cardiovascular disease risk predictors, data regarding the association of CRP and menopause are controversial. In this study, we measured CRP by a high-sensitivity method (hsCRP), cholesterol, lipoproteins, and triglycerides in normal and overweight postmenopausal women. METHODS Body weight,(More)
OBJECTIVE To examine the association of six glutathione transferase (GST) gene polymorphisms (GSTT1, GSTP1/rs1695, GSTO1/rs4925, GSTO2/rs156697, GSTM1, GSTA1/rs3957357) with the survival of patients with muscle invasive bladder cancer and the genotype modifying effect on chemotherapy. PATIENTS AND METHODS A total of 105 patients with muscle invasive(More)
PURPOSE To clarify the role of genetic polymorphisms of GSTO1 (rs4925) and GSTO2 (rs156697) in individual susceptibility to urinary bladder cancer. METHODS Case-control study consisting of 187 patients with histologically confirmed transitional cell carcinoma (TCC) of urinary bladder and 140 age- and gender-matched cancer-free controls was carried out.(More)
