摘要 目的 探讨蛋白酶体抑制剂MG132抑制晶状体上皮细胞系SRA01/04增殖的机制.方法 MTT比色法检测MG132对SRA01/04细胞增殖的影响,流式细胞术检测MG132对SRA01/04细胞凋亡的影响,荧光显微镜下Annexin V/FITC-PI双染法观察MG132对SRA01/04细胞的影响.结果 MG132随着浓度的增高对SRA01/04细胞增殖的抑制作用逐渐增强,作用36 h时半数有效抑制浓度IC50为2.48μmol/L.2.5、5.0μmol/L MG132分别与SRA01/04细胞作用24 h,早期细胞凋亡率分别为(5.75±0.24)%和(10.23±2.68)%,而对照组为(0.34±0.26)%,差异有统计学意义(P<0.05).结论 MG132诱导细胞凋亡来抑制SRA01/04细胞的增殖,可起到防治后发性白内障的作用.
