Glutathione and its metabolizing enzymes were studied in erythrocytes of cattle suffering from urinary bladder cancer and associated hematuria. The concentration of glutathione (GSH) and GSH peroxidase activity were subnormal in the affected animals, whereas activities of GSH reductase and GSH
Glutathione S-transferases (GSTs) contain a series of critical enzymes regulating proliferation or apoptosis in the tumor microenvironment. Data from publications about the correlation between Glutathione S-transferase Pi 1 (GSTP1) gene 313 A/G (rs1695) polymorphism and bladder caner Exposure to potential carcinogens is an etiologic factor for renal cell carcinoma (RCC) and transitional cell carcinoma (TCC) of the urinary bladder. Cytosolic glutathione S-transferases (GSTs) are a superfamily of enzymes that protect normal cells by catalyzing conjugation reactions of
A comparative study of reduced glutathione (GSH) concentrations and activities of GSH related-enzymes in urinary bladder transitional epithelium (UBTE), urinary bladder nontransitional tissue (UBNT), and liver of the rabbit, was carried out to investigate the reasons for the susceptibility of UBTE
Foreign compound-metabolizing enzymes may modify the risk of chemically induced cancer. We wanted to examine enzymes with putative relevance in urinary bladder cancer using molecular genetic analyses of heritably polymorphic enzymes. Arylamine N-acetyltransferase (NAT2); glutathione S-transferases
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. Using a multiplex polymerase chain reaction (PCR) based method, the frequency of the
Urinary bladder cancer (UBC) is a common disease worldwide with a higher incidence rate in developed countries. Organochlorine pesticides (OCPs), potent endocrine disrupters, are found to be associated with several cancers such as prostate, breast, bladder, etc. Glutathione S-transferase (GST) is a
This study sought to determine the role of copy number variants (CNV) combined with other genetic variants in the Glutathione S-transferases Mu class1 (GSTM1) promoter in the development of urinary bladder cancer. TaqMan real-time PCR and direct sequencing were used to determine genetic variants.
Chronic inhalation of quartz-containing dust produces reversible inflammatory changes in lungs resulting in irreversible fibrotic changes termed pneumoconiosis. Due to the inflammatory process in the lungs, highly reactive substances are released that may be detoxified by glutathione S-transferases.
OBJECTIVE
This study sought to reveal mechanisms for differential regulation of reactive oxygen species (ROS) in histone deacetylase inhibitor FK228-induced selective apoptosis of oncogenic H-Ras-expressing human cancer cells.
METHODS
Human urinary bladder cancer J82 and oncogenic H-Ras-expressing
Enzyme-linked immunoassays (ELISAs) based on the double-antibody sandwich technique have been developed for the quantitative analysis of the major human cytosolic class Pi, Mu and Alpha glutathione transferases (GSTs). The procedures were optimized with respect to antibody concentration for coating
Glutathione S-transferase M1 (GSTM1) is a foreign compound-metabolizing enzyme with a heritable complete lack of activity in about 50% of Caucasians. GSTM1 deficiency may predispose individuals to urinary bladder cancer. Thus, a hospital-based case-control study was performed with 296 patients with
This study was performed to investigate the frequency of bladder cancer in patients with an occupational history such as underground hard coal mining and/or painting after the structural change in the local industry. A total of 206 patients with bladder cancer and 207 controls were enlisted
The hGSTM1 null genotype has been associated with increased susceptibility to urinary bladder cancer. However, the extent to which the GSTM1 subunit actually contributes to GST activities in mammalian urinary bladders is not clear. For adult mice, urinary bladders exhibited GST activity which was
