Assessment of the antioxidant/prooxidant status of murine skin following topical treatment with 12-O-tetradecanoylphorbol-13-acetate and throughout the ontogeny of skin cancer. Part I: Quantitation of superoxide dismutase, catalase, glutathione peroxidase and xanthine oxidase.

Abstract excerpt

The activities of several enzymes involved in reactive oxygen production and detoxification were quantified in murine skin during the ontogeny of chemically induced skin cancer. Relative to solvent-treated controls, the specific activities of epidermal superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPX) were reduced approximately 45, approximately 60 and approximately 24% respectively, 24...
