摘要 目的观察特异性mTOR抑制剂依维莫斯联合顺铂对喉癌细胞Hep-2的作用,并探讨其内在的分子机制。方法 Hep-2细胞经依维莫斯和顺铂处理后,以MTT法检测细胞的增殖情况,金正均法计算q值判断两药的相互作用。以流式细胞仪检测细胞凋亡,Western blot检测Bcl-2的表达。结果依维莫斯联合顺铂可抑制Hep-2细胞增殖,与单独用药组相比差异有统计学意义(P<0.05),金正均法显示q值>1.15,显示二者有协同作用。依维莫斯和顺铂均可使Hep-2细胞发生凋亡,并且但在两者联用时凋亡率达到最高。经依维莫斯和顺铂作用后的Hep-2细胞表达Bcl-2较处理前明显下降。结论体外依维莫斯和顺铂均可抑制Hep-2细胞增殖,诱导其发生凋亡,并可使Bcl-2的表达下调,且两者联合应用时可显著增加其抑制作用,具有协同作用。
