摘要 目的探讨姜黄素对人骨肉瘤U2OS细胞系增殖、凋亡及侵袭的影响。方法取处于对数生长期的人骨肉瘤U2OS细胞,随机分为4组,A、B、C、D组分别加入PBS缓冲液、姜黄素5、10、20μmol/L,采用MTT法测算各组细胞生长抑制率,流式细胞术检测各组细胞凋亡情况,Transwell细胞侵袭实验观察细胞侵袭能力变化。结果A、B、C、D组第48小时细胞生长抑制率分别为0、13.2±2.5、23.6±4.3、41.5±6.2,第72小时细胞生长抑制率分别为0、23.1±5.1、43.2±2.7、65.7±7.3,与同组48 h比较差异均有统计学意义(P均<0.05)。随着姜黄素浓度的升高,U2OS细胞的凋亡指数明显增高,呈浓度依赖性。U2OS细胞培养24 h后A、B、C、D组细胞凋亡指数分别为10.01%、18.76%、24.68%、42.81%。四组间两两比较,P均<0.05。U2OS细胞培养72 h后A、B、C、D组每高倍镜下穿膜细胞数目分别为96.8±8.2、82.4±7.1、76.3±6.5、53.4±3.3,C、D组与A组比较,P均<0.05。结论姜黄素对人骨肉瘤细胞系增殖有明显的抑制作用,且呈浓度及时间依赖性,能诱导细胞凋亡,降低细胞侵袭能力。
