摘    要:目的观察甘氨脱氧胆酸盐(glycodeoxycholate,GCDC)诱导人正常肝细胞株HL.7702凋亡过程中caspase.3,8,9活性的变化,探讨其凋亡机制。方法体外培养HL-7702细胞,以GCDC为处理因素,用AnnexinV.F1TC/PI双染色法结合流式细胞技术仪检测细胞凋亡率,比色法测定caspase-3,8,9活性。结果100、150、200、250μmol/L的GCDC处理HL-7702细胞24h后以及250μmol/LGcDc处理细胞4、8、12、24h后,其细胞凋亡率、caspase-3,8,9活性明显升高,与对照组比较,差异有统计学意义(P〈O.05)。结论GCDC可通过活化caspase-8,9,进而激活caspase-3从而诱导肝细胞凋亡。

关 键 词:甘氨脱氧胆酸盐  细胞凋亡  caspase

Abstract:Objective To investigate the apoptosis and changes of caspase-3,8,9 activities in cultured normal human hepatocyte HL-7702 cells induced by glycodeoxycholate(GCDC)in vitro and to explore the possible mechanism of hepatocyte apoptosis.Methods HL-7702 cells were cultured with GCDC.The apoptosis ratio of HL-7702 cells was determined by Annexin V-FITC/PI double staining.Colorimetric method was used to measure caspase-3,8,9 activities.Results When hepatocytes were incubated with GCDC for 24h,the apoptotic ratio ...
