Abstract:: |
Objective To investigate radiation-protective effect of resveratrol and its molecular mechanism. Methods Kunming mice were ig administered with resveratrol before 60Coγ-irradiation.Thirty-day survival rate and the average life span of dead mice post-irradiation were observed.The apoptosis of spleen from irradiatied mice was detected by FACS and in situ termianl labeling method.The effect of resveratrol on the activities of Caspase-3 and Caspase-8,and the expression levels of Bcl-2 and Fas were examined. Results Administration with resveratrol resulted in increases of 30-day survival rate and prolongation of average life span of the dead mice.Aoptotic rate of spleen cells decreased,expression level of bcl-2 increased,the expression of Fas did not change,and the activities of Caspase-3 and Caspase-8 increased in spleen cells of irradiation groups. Conclusion The results indicate that resveratrol has radiation-protective effect and its mechanism might be related with its suppression of apoptosis of radiation-sensitive cells. |
