简介：目的：探讨线粒体膜电位（△ψm）、Caspase3在As2O3诱导ACC-2细胞凋亡中的作用。方法：进行ACC-2细胞培养,将As2O3建立不同药物浓度梯度（0,1.0,2.0,4.0,8.0μmol/L）分别作用于ACC-2细胞,用Rh123染色,流式细胞仪检测8.0μmol/LAs2O3作用前、后（24h）,ACC-2细胞的线粒体膜电位（△ψm）变化;用多功能酶标仪进行Caspase3活性检测。结果：空白对照组ACC-2细胞内Rh123荧光强度最强,8.0μmol/LAs2O3处理组ACC-2细胞内Rh123荧光强度减弱,其差异有显著性（P〈0.05）;随着As2O3药物浓度的增高（0,1,2,4,8μmol/L）,ACC-2细胞的Caspase3酶活力单位逐渐增加。结论：As2O3作用于ACC-2细胞,可通过降低线粒体膜电位从而引起细胞凋亡。随着As2O3药物浓度的增高,ACC-2细胞的Caspase3酶活力单位逐渐增加,Caspase3被激活,细胞可发生不可逆转的凋亡过程。
