杏仁种皮黑色素对果蝇的紫外辐射保护作用
Anti-UV Irradiation Effect of Melanin Derived from Apricot Kernel Skin in Drosophila
摘要
Abstract
After UV irradiation treatment,two Drosophila strains,Xinong 12 and Drosophila Zhongnong e,were cultured in a medium supplemented with melanin derived from apricot kernel skin(AS-M).Fecundity,lifetime,SOD activity,MDA content,protein concentration,total antioxidant capacity(T-AOC) were measured to evaluate the anti-UV irradiation effect of AS-M.Compared with control group,UV irradiation substantially reduced fecundity,lifetime and T-AOC in both Drosophila strains,protein concentration and SOD activity tended to first increase and then decrease,and MDA content markedly increased.AS-M addition at concentrations varying from 0.02 to 0.2 mg/mL could distinctly improve the fecundity of the two Drosophila strains compared with 2 min UV irradiation group.The difference between 0.02 mg/mL and 0.2 mg/mL treatment groups did not reach a significant level.Compared with 5 min UV irradiation group,AS-M addition resulted in a significant increase in lifetime,protein concentration,T-AOC,SOD activity and a reduction in MDA content.These results demonstrated that AS-M has anti-UV irradiation effect in Drosophila.关键词
