摘要 目的比较甘精胰岛素、地特胰岛素对人乳腺癌MCF-7细胞增殖的影响。方法体外培养人乳腺癌MCF-7细胞。甘精胰岛素或地特胰岛素以不同浓度、时间或联合丝裂原活化蛋白激酶激酶1(MAPKK1)、磷脂酰肌醇-3-激酶(PI3K)抑制剂作用MCF-7细胞,噻唑蓝(MTT)法测细胞数目,Western blotting法测细胞外信号调节蛋白激酶1/2(Erk1/2)和蛋白激酶B(Akt)磷酸化程度,流式细胞仪测细胞周期。结果甘精胰岛素10、100、1 000 U/L作用48 h或1 U/L作用48、72、96 h均引起MCF-7细胞增殖(P均<0.05),地特胰岛素增殖作用不明显,两组差异有统计意义(P均<0.05)。甘精胰岛素、地特胰岛素10 U/L作用MCF-7细胞24 h,均出现S+G2/M期细胞增多和Erk1/2、Akt磷酸化程度升高,甘精胰岛素组与对照组比较差异有统计意义(P均<0.05)。使用抑制剂后,甘精胰岛素对MCF-7细胞的增殖作用被抑制(P<0.05),甘精胰岛素联合PD98059后抑制更明显(P<0.05)。结论甘精胰岛素对MCF-7细胞增殖作用明显,呈浓度、时间依赖关系,其中MAPK和PI3K/Akt通路均被激活,但MAPK通路更重要。地特胰岛素对MCF-7细胞增殖作用不明显。
