摘要 目的探讨芦荟大黄素(AE)对人脑胶质瘤SHG44细胞增殖、凋亡的影响及其相关机制。方法将人脑胶质瘤SHG44细胞分为对照组(未经药物处理)及实验组(AE浓度分别为20、40、80和160μmol/L);采用CCK-8法检测AE对SHG44细胞增殖的影响;应用流式细胞仪检测AE不同浓度处理组胶质瘤细胞凋亡情况;通过比色法测定细胞内caspase-3的相对活性。结果 AE对SHG44细胞生长具有抑制作用,且呈浓度依赖性;随着AE浓度的增高,凋亡率逐渐增加,与对照组相比差异具有统计学意义(P<0.05);AE作用于SHG44细胞后,处理组的Caspase-3相对活性明显升高,并存在浓度依赖关系。结论 AE能够抑制胶质瘤SHG44细胞增殖,诱导肿瘤细胞凋亡,相关机制可能涉及Caspase-3活化。
