摘要 目的研究BI2536对肺癌细胞株A549体外生长的影响,探讨BI2536抑制肺癌细胞的机制。方法体外培养肺癌A549细胞,不同浓度BI2536作用下,MTI"检测肺癌细胞增殖抑制,倒置显微镜观察肺癌细胞生长,westerllblot检测肺癌细胞中Plkl蛋白表达,流式细胞仪检测肺癌细胞的周期分布和凋亡情况。结果不同浓度(5-60μg/L)的BI2536作用48h,细胞增殖抑制率最高可达(46.0±1.9)%。光镜下可见细胞形态改变,生长受抑,有丝分裂受阻。药物浓度达到40μg/L时,Plkl蛋白表达受到完全抑制,G2/M期细胞达到55.6%,凋亡率达23.26%。结论BI2536通过抑制肺癌细胞株A549中Plkl蛋白表达,使肺癌细胞发生G2/M期阻滞,引起细胞凋亡,起到抑制肺癌细胞增殖的作用。
