摘要: 目的:观察薯蓣皂苷元(diosgenin, Dio)对人低分化胃腺癌细胞株(MGC-803)的细胞分裂和集落形成的影响,初步探讨其杀伤肿瘤细胞的机制。 方法:采用四唑蓝(MTT)比色法、平板集落形成实验以及[3H]-TdR掺入实验。结果:MTT法检测Dio作用24、48、72 h的半数抑制浓度(IC50)为56.290、27.837、17.723 mg•L-1;平板集落形成实验显示Dio半数集落形成抑制浓度为5.486 mg•L-1;Dio在较低浓度(3.750和7.500 mg•L-1)下,可直接抑制MGC-803细胞DNA的合成。结论:Dio能够明显抑制MGC-803的细胞分裂和集落形成。

Abstract: Objective To study the effect of diosgenin on the cell diversion and colony forming of human poorly differentiated gastric adenocarcinoma cell line MGC-803,and investigate the mechanism of cell death induced by diosgenin. Methods MTT assay,colony forming experiment and [3H]-TdR incorporation into DNA were used. Results After incubated with diosgenin for 24, 48, and 72 hours, the IC50 were 56.290, 27.837, and 17.723 mg•L-1,respectively, detected by MTT. The concentration which inhibited half colony forming was 5.486 mg•L-1. It directly inhibited the synthesis of DNA of MGC-803 in lower concentrations (3.750 and 7.500 mg•L-1). Conclusion Diosgenin has an obvious inhibitory effect on the cell diversion and colony forming of MGC-803.
