【摘要】 目的:观察依地福新对人宫颈癌Hela细胞的体外生长抑制作用,并进一步探讨其作用机制。方法:细胞中分别加入不同浓度的依地福新(0.5、1.0、5.0、10.0μmol.L-1)处理96h,并设立未加依地福新的对照组。应用MTT法检测细胞增殖活性;流式细胞仪检测细胞周期分布;染色法检测细胞凋亡率。结果:与对照组比较,不同浓度依地福新处理Hela细胞24～96h后,细胞增殖显著受到抑制,并呈浓度及时间依赖性;1.0、5.0、10.0μmol.L-1浓度依地福新处理72h后,Hela细胞G0/G1期细胞数量显著增加,S期细胞数量显著降低(P<0.01);各浓度组细胞凋亡率均显著增加(P<0.01)。结论:依地福新对Hela细胞具有生长抑制作用,其机制可能与阻滞细胞周期及诱导凋亡有关。更多还原

【Abstract】 OBJECTIVE:To investigate the effect of edelfosine on the proliferation of Hela cells and its mechanism.METHODS:Hela cells were treated with edelfosine at doses of 0(control),0.5,1.0,5.0,10.0 μmol·L-1 for 96 h.MTT assay,flow cytometry,and staining were performed to determine the cell proliferation activity,cell cycle,and apoptotic rate.RESULTS:As compared with control,the cell proliferation activity of Hela cells was inhibited in a dose-and time-dependent manner after being treated by edelfosine for 24～96 h.After being treated by edelfosine(1.0,5.0,10.0 μmol·L-1) for 72 h,the number of Hela cells significantly increased in G0/G1 phase but decreased in S phase(P<0.01);and the apoptotic rate of Hela cells in different concentrations of edelfosine increased significantly(P<0.01).CONCLUSION:Edelfosine could inhibit the growth of Hela cells by blocking cell cycle and inducing apoptosis.更多还原
