摘要
目的观察毛蕊异黄酮对顺铂抑制胃癌细胞增殖的增强作用。方法将BGC823细胞分为4组,分别用生理盐水、顺铂、毛蕊异黄酮和2种药物联合处理,检测不同时间点、不同处理因素下的细胞增殖情况。进一步检测影响细胞增殖的相关蛋白,确定毛蕊异黄酮联合顺铂抑制胃癌细胞增殖的方式。结果对细胞作用24 h后,20μg/m L顺铂,10μg/m L毛蕊异黄酮,以及2种药物联合处理组对BGC823细胞的增殖抑制率分别为56.44%±2.08%,9.52%±2.77%和74.44%±0.82%。药物联合使用后对细胞的抑制率明显高于单个药物处理组,各组数据间差异有统计学意义(P<0.05)。并且无论是在蛋白水平还是RNA水平上,毛蕊异黄酮均可以显著增强顺铂对Cyclin D1,CDK4和CDK6蛋白的抑制作用。结论毛蕊异黄酮可以显著提高顺铂对BGC823细胞增殖的抑制率,2种药物联合使用可以降低顺铂单独使用所导致的毒副作用。
