Abstract
目的 研究小分子化合物蒽贝素(Embelin)是否能协同增强肿瘤坏死因子相关的凋亡诱导配体(tumor necrosis factor-related apoptosis-inducing ligand,TRAIL)诱导乳腺癌细胞MDA-MB-231的凋亡性死亡.方法 应用Embelin、TRAIL或者联合应用分别处理MDA-MB-231细胞.MTT法测定药物处理的细胞毒性,APOP-BRDU试剂盒及流式细胞仪测定细胞凋亡率,Western blot观察Caspase3,9和PARP的表达水平.半定量PCR和Western blot分别观察Embelin处理以后X连锁的凋亡抑制蛋白(X-linked inhibitor of apoptosis protein,XIAP) mRNA、蛋白表达水平的变化.结果 MDA-MB-231细胞呈TRAIL部分耐药,Embelin的细胞毒性在MDA-MB-231细胞呈浓度依赖性.亚毒性浓度的Embelin能显著增强TRAIL诱导的细胞毒性、凋亡率、Caspase 3,9的活化和PARP的切割.但是,亚毒性浓度的Embelin未直接改变XIAP的蛋白和mRNA表达水平.结论 Embelin能显著增强TRAIL诱导的乳腺癌细胞MDA-MB-231的凋亡性死亡.
