目的探讨青蒿琥酯(A RT)对肝癌细胞生长的抑制作用及其机制。方法以不同浓度青蒿琥酯作用肝癌SMMC-7721细胞24h,采用MTT法检测细胞生长抑制率(IC5 0)值。根据I C5 0值选取3个青蒿琥酯浓度(30、60、120μg/ml)进行后续实验。以不同浓度青蒿琥酯(0、30、60、120μg/ml)作用SM MC-7721细胞24h,0μg/ml青蒿琥酯以生理盐水代替青蒿琥酯作为对照组,分别命名为对照组、30μg/ml ART组、60μg/ml ART组、120μg/ml A RT组。倒置显微镜观察细胞形态;流式细胞术检测各组细胞周期、细胞凋亡、细胞线粒体膜电位及B c l-2和B a x蛋白表达水平。结果 MTT结果显示,青蒿琥酯对肝癌SMMC-7721细胞有生长抑制作用,且呈剂量依赖性,IC_(50)=60.27±1.51μg/ml。倒置显微镜下观察,青蒿琥酯作用24h后,SMMC-7721细胞中呈现不同程度的死亡细胞,且随着青蒿琥酯浓度增加,死亡破碎细胞也增加。30、60、120μg/ml ART组细胞凋亡率(分别为4.44%±0.32%、6.54%±0.84%、12.92%±1.22%)与对照...
【英文摘要】
Objective To investigate the inhibitor y effect of artesunate(ART) on hepatoma cells and its mechanism. Methods The growth inhibitory rate of SMMC-7721 cells was detected by MTT after the treatment of different concentrations of artesunate. IC_(50) value of artesunate on SMMC-7721 cell for 24 h was calculated. Three concentrations(30, 60, 120μg/ml) of artesunate were selected depending on the IC_(50) value. SMMC-7721 cells were divided into four groups: control group and 30, 60, 120μg/ml ART groups. Cell mo...
