2、5、1、2mg/m1)与肝癌细胞共培养24h后,流式细胞仪检测肝癌细胞凋亡,线粒体膜电位试剂盒(Jc.1)检测线粒体膜电位变化;比色法测定1.0mg/mi丹参多酚酸盐作用后肝癌细胞内caspase-8、caspase-9及caspase-3的活性,流式细胞仪检测培养体系内加入easpase-9抑制剂(z.LEHD—fmk)或caspase-3抑制剂(z.DEVD.fmk)后细胞凋亡率的变化,Westernblotting检测肝癌细胞内线粒体凋亡途径相关蛋白Bax、Bel-2表达水平。结果:丹参多酚酸盐显著诱导肝癌细胞SMMC-7721凋亡(P<0.05),
3、同时线粒体膜电位随着药物浓度的升高而加剧下降(P<0.05)。1.0ms/ml丹参多酚酸盐处理肝癌细胞24h后caspase-9与caspase-3的活性明显升高(P0.05);当培养体系内加入c船p脑e-9或c鹅pase-3活性抑制剂后,丹参多酚酸盐诱导肿瘤细胞凋亡的作用明显降低(P4、赖的趋势,其机制与线粒体凋亡途径有关。[关键词】丹参多酚酸盐;肝癌细胞;凋亡;线粒体[中图分类号]R735.7;R730.5[文献标志码]A[文章编号]1(酊7-385X(2010)01-0062-05SalvianolateinducesapoptosisofhumanhepatomaSMMC-7721cellsthroughmitochondrialpathwaySONGShao—hua‘,GUOWen—yuan’,FUZhi·ren,LIUFang,WANGZheng-xin,DINGGuo·shan(OrganTransplanta-tionCen5、ter,ChangzhengHospital,SecondMilitaryMedicalUniversity,Shanghai200003,China)[Abstract]Objective:Toexploretheapoptosis—inducingeffectofsalvianolateonhepatomaSMMC-7721cellsandtheunderlyingmechanism.Methods:SMMC07721cellswereco—cultured讥vitrowithdifferentconcentrations(0.5,1,2ms/m1)o6、fsalvianolatefor24h.TheapoptoticSMMC一7721ceilswereexaminedbyflowc”ometry,andthechangesofmitochondrialtransmembranepotentialwereexaminedbymitochondrialtransmembranepotentialJC—lkit.Theactivitiesofcasp鹊e-8,caspase-9,andcasp鹅e.3weredetectedbyspectmphotometryinthehepatomaSMMC-7721cell7、safterCO-culturedwith1ms/nasalvianolate.ThechangesofapoptoticSMMC·7721cellsinducedbysalvianolateinthepresenceorabsenceofc鹊pase-9inhibitororcaspase-3inhibitorweremeasuredbyflowc”ometry.Theexpressionsofpro—apoptotieproteinBaxandanti—apoptoticproteinBcl-2weredetectedbyWesternblotting8、analysis.Results:Salvianolatesign
