Objective To investigate the effects of acute oxidative stress induced by H_2O_2 on expression of senescence marker protein30(SMP30) and morphology,survival rate of human lens epithelial cells(HLECs).Methods HLECs were treated with H_2O_2(0 μmol·L~(-1),100μmol·L~(-1),200 μmol·L~(-1),300 μmol·L~(-1)) for 24 hours,the acute oxidative stress models were established,the changes of cell morphology was observed,and MTT was used to analyze the cells state,the expressions of SMP30 were measured by Western blot.Resu...

衰老标记蛋白30(senescence marker protein 30,SMP30)不仅具有稳定钙离子浓度、抗凋亡、抗氧化应激的作用[1-2],还能抑制细胞增殖,参与调控DNA、RNA与多种酶的表达[3]。SMP30作为新型
的抗衰老因子是近年来研究热点。早期研究发现SMP30在人多种组织器官中均有表达并发挥作用?
