摘要:

目的:探讨雷帕霉素(RAPA)与阿霉素(ADM)联合应用对肝癌细胞BEL-7402增殖和迁移的影响,阐明其作用机制。方法:选取处于对数生长期肝癌细胞株BEL7402随机分为空白对照组、乙醇溶媒组、RAPA组、ADM组以及联合用药组,采用MTT法检测各组细胞6 d内的增殖情况,采用RT-PCR方法检测cyclin D1和MMP-2 mRNA表达水平,采用Western blotting法检测cyclin D1蛋白表达水平。结果:细胞培养后第3天起,联合用药组细胞增殖速度显著低于RAPA组、ADM组、乙醇溶媒和对照组(P<0.01)。联合用药组cyclin D1 mRNA相对表达量(0.63)明显低于RAPA组(0.77)、ADM组(0.76)和对照组(1.02),联合用药组MMP-2 mRNA相对表达量(0.88)明显低于RAPA组(1.40)、ADM组(1.28)和对照组(1.98),联合用药组cyclin D1蛋白相对表达量(0.33)明显低于RAPA组(0.75)、ADM组(0.74)和对照组(0.92)。结论:RAPA与ADM联合应用可以增强肝癌细胞系BEL-7402对ADM的敏感性,其机制可能与抑制MMP-2和cyclinD1基因的转录及cyclinD1蛋白的表达有关。

Abstract:Objective
To investigate the combination effects of rapamycin(RAPA) and adriamycin  (ADM) on the proliferation and migration of hepatoma cell BEL-7402,and furthermore  analyze the possible mechanisms. Methods The  hepatoma cell BEL-7402 in logarithmic growth phase were  selected as the research object,and  were randomly divided into five groups:blank control group,vehicle group,RAPA group ,ADM group and combination group.The cell proliferation in 6 d in  five groups was detected by MTT,the cyclin D1 mRNA and MMP-2 mRNA expressions in various groups were detected by RT-PCR,and the cyclin D1 protein expression was detected by Western blotting. Results From the 3rd day to the 6th day of the cell culture,the cell proliferation rate in combination group was lower than those in control,vehicle,RAPA and ADM groups(P<0.01).The expression of cyclin D1 mRNA in combination group(0.63)was lower than those  in control(1.02),RAPA(0.77)and ADM(0.76) groups.The expression of MMP-2 mRNA in combination group(0.88)was lower than those in control(1.98),RAPA(1.40) and ADM (1.28) groups.The expression of cyclin D1 protein in combination group(0.33) was lower than those in control(0.92),RAPA(0.75)and ADM (0.74) groups. Conclusion The combination treatment of RAPA and ADM can improve the sensitivity of hepatoma cell BEL-7402 to ADM,the mechanism perhaps lies in the combination of the two drugs can inhibit the expressions of cyclin D1 mRNA,MMP-2 mRNA and cyclin D1 protein more significantly.
