摘要 目的:观察Caveolin-1蛋白在胃癌细胞系BGC823中的表达情况,并探讨胃癌细胞BGC823经他莫昔芬(TAM)处理后,Caveolin-1蛋白表达的变化。方法:使用5×10-6M和1×10-5M TAM处理胃癌细胞系BGC823 24h后,通过免疫荧光细胞化学的方法及细胞计数,检测细胞的凋亡情况以及Caveolin-1蛋白的表达变化。结果:Caveolin-1在胃癌BGC-823中高表达,经不同浓度的TAM处理24h后Caveolin-1的表达均下降(P<0.05),同时均出现明显凋亡(P<0.05)。Caveolin-1的表达下降与细胞凋亡数呈正相关关系(P<0.05)。结论:Caveolin-1在胃癌细胞BGC823中发挥生物学作用且与TAM介导的BGC823细胞的凋亡相关。
