| Abstract: | Superoxide dismutase (SOD) is an antioxidant enzyme with multiple metal cofactors that can specifically clear reactive oxygen species (ROS), which plays an important role in a variety of ultraviolet-induced lesions. Therefore, SOD has the anti-ultraviolet radiation effect. The objective of this study was to compare the differences in the anti-ultraviolet radiation effect of SOD with distinct metal cofactors: Cu/Zn-SOD and Mn-SOD. SOD was first purified using hydrophobic interaction chromatography and ion-exchange chromatography. Second, the Methylthiazolyldiphenyl-tetrazolium bromide method and cell senescence kits were used to study the protective effect of SOD on ultraviolet-induced cell damage. Finally, the protective effect of SOD on ultraviolet -induced skin damage was histopathologically evaluated, and the expression levels of malondialdehyde (MDA) and matrix metalloproteinases (MMPs) in tissues were detected. The results showed that Cu/Zn-SOD was superior to Mn-SOD in promoting cell proliferation, alleviating cell damage, protecting skin structure, and regulating the expression levels of MDA and MMPs, and it has no side effects. In conclusion, Cu/Zn-SOD had a better anti-ultraviolet radiation effect than Mn-SOD, and it can be used in anti-aging and anti-ultraviolet skin-care products. |
