摘要 目的探讨索拉非尼联合紫杉醇(PTX)对肝癌细胞huh-7的杀伤作用。方法用MTT法检测索拉非尼、紫杉醇单药及其联合对huh-7细胞的增殖抑制,同时采用流式细胞仪检测细胞周期及凋亡情况。结果索拉非尼单药及PTX单药对huh-7均有明显抑制作用,两药联合具有协同作用(P<0.05),其中索拉非尼4μmol/L+PTX0.04μmol/L为最佳浓度组合。索拉非尼主要使细胞阻滞于G1期,PTX则使细胞阻滞于G2期和M期。两药联用后同时阻滞于G1及G2/M期。联合组凋亡率明显高于单药组,差异有统计学意义(P<0.05)。结论索拉非尼和PTX对肝癌huh-7细胞有增殖抑制及促凋亡作用,两药联合表现为协同或相加作用。
