摘要 目的探讨紫檀芪(PTE)对人乳腺癌MDA-MB-231细胞系增殖及凋亡的影响。方法细胞分为正常对照组、PTE组(10、20、40、80μmol/L),各组细胞分别处理24、48、72 h。MTT法检测各组细胞存活率;黏附实验测定各组细胞黏附率;TUNEL法测定各组细胞凋亡率;Caspase-Glo3/7定量试剂盒测定细胞Caspase3/7的表达情况。结果MTT结果显示PTE对MDA-MB-231细胞增殖有抑制作用(P<0.01),呈药物浓度时间依赖效应,其中80μmol/L处理72 h组抑制效果最明显。黏附实验(48 h)结果显示PTE可以减弱MDA-MB-231细胞黏附能力(P<0.01),并呈浓度依赖效应。TUNEL检测(48 h)结果显示PTE可以增加MDA-MB-231细胞的凋亡率(P<0.01)。Caspase3/7检测结果显示PTE可以使Caspase3/7活性升高(P<0.01)。结论 PTE可抑制乳腺癌MDA-MB-231细胞增殖,促进其凋亡。
