[ 1 ] - Genetic polymorphisms of superoxide dismutase-1 A251G and catalase C-262T with the risk of colorectal cancer

Oxidative stress is significant in numerous types of disease including cancer. To protect cells and organs against reactive oxygen species (ROS), the body has evolved an antioxidant protection system that involved in the detoxification of ROS. Single nucleotide polymorphisms (SNP) of anti-oxidative enzymes may dramatically change the activity of the encoded proteins; therefore, certain alleles ...

[ 2 ] - The relationship between NQO1 C609T and CAT C-262T genetic polymorphisms and the risk of age-related cataracts

Cataract is multi-factorial eye disease identified by the disturbance of the transparent ocular lens. There is significant evidence suggesting oxidative damage as a major cause of initiation and progression of numerous diseases including cataracts. NAD(P)H:quinone oxidoreductase 1 (NQO1; OMIM: 125860) and catalase (CAT, OMIM: 115500) are antioxidant enzymes that prevent cells from oxidative str...

[ 3 ] - Association of CAT C-262T and SOD1 A251G single nucleotide polymorphisms susceptible to gastric cancer

Oxidative stress is known to be one of the major factors involved in the development and progression of cancer. Oxidative stress can occur due to an imbalance between concentrations of reactive oxygen species and antioxidant capacities. Catalase (CAT; OMIM 115500) and superoxide dismutase 1 (SOD1; OMIM 147450) play important roles in the primary defense against oxidative stress. In the present ...

[ 4 ] - Effect of Cyclosporine A on the expression of GSTO2 metabolizing enzyme in Jurkat cell line

Cyclosporine A (CsA), a cyclic polypeptide metabolite extracted from the fungus, is used clinically to combat organ graft rejection in transplant subjects. Previous studies have shown that CsA exposure enhances the production of reactive oxygen species (ROS) and lipid peroxidation, which are directly involved in CsA toxicity. To protect cells and organs against ROS, the human body has evolved a...
