Melatonin enhances antioxidative enzyme gene expression (CAT, GPx, SOD), prevents their UVR‐induced depletion, and protects against the formation of DNA damage (8‐hydroxy‐2'‐deoxyguanosine) in ex vivo human skin

Abstract excerpt

UV radiation (UVR) induces serious structural and functional alterations in human skin leading to skin aging and carcinogenesis. Reactive oxygen species are key players in UVR-mediated photodamage and induce the DNA-base-oxidized, intermediate 8-hydroxy-2'-deoxyguanosine (8-OHdG). Herein, we report the protective action of melatonin against UVR-induced 8-OHdG formation and depletion of antioxidative enzymes using...
