目的:探讨FTY720对卵巢癌细胞系OVCAR-3增殖的影响及其诱导凋亡的作用机制。方法应用不同浓度的FTY720作用于卵巢癌细胞系OVCAR-3,MTT法检测细胞生长抑制率,应用Annexin V-FITC/PI细胞凋亡双染试剂盒检测细胞凋亡率及分析细胞周期的变化,Western-blot法分析凋亡相关蛋白的变化。结果 FTY720对OVCAR-3卵巢癌细胞系增殖的抑制作用具有时间、剂量依赖性。随着FTY720作用时间的延长,OVCAR-3细胞凋亡数量增多,且G1期细胞比例逐渐上升。 Western-blot结果显示Caspase3和Caspase9都受到了激活。结论 FTY720可以诱导人卵巢癌细胞系OVCAR-3发生凋亡,并且激活内源性Caspase途径和诱导细胞发生G1期阻滞,这可能是FTY720抑制卵巢癌细胞生长的作用机制之一。

Objective To investigate the effect of FTY720 on the proliferation of OVCAR-3 ovarian cancer cells and its mechanism of apoptosis-inducing in vitro.Methods OVCAR-3 cells under different concentration of FTY720 were collected.The inhibition rates of cells were determined by MTT assay to evaluate the effect of FTY720.The percentage of apoptosis and cell cycle progression were detected by Annexin V-FITC/PI.Apoptosis related proteins were determined by western-blot.Results Growth inhibition and apoptosis induction were evoked by different concentrations of FTY720 in OVCAR-3 cells in time and concentration dependent manner.FTY720 greatly inhibited human ovarian cancer cell OVCAR-3 proliferation.This effect was associated with G1 phase cell cycle arrest and apoptosis.Wester-blot showed that caspase3 and caspase9 were activated.Conclusion FTY720 can inhibit the proliferation and induce OVCAR-3 cells apoptosis.Apoptosis induced by FTY720 may be regulated through G1 phase cell cycle arrest and the activation of endogenous caspase pathway.
