摘要: 目的: 探讨黄芪皂苷Ⅱ(AstragalosideⅡ, ASⅡ)对肝癌多药耐药性的逆转作用。方法: MTT法检测人肝癌多药耐药细胞BEL-7402/FU对化疗药物的敏感性和逆转耐药倍数,RT-PCR法检测多药耐药蛋白-1(MDR1)基因表达,免疫细胞化学法检测P-糖蛋白(P-gp)蛋白表达水平,流式细胞仪检测ASⅡ对细胞内Rhodamine123的蓄积影响。结果: BEL-7402/FU细胞对5-氟尿嘧啶(5-FU)、阿霉素、丝裂霉素的耐药倍数分别为 19.64、1.98、1.92。0.04、0.08 mg/mL 的ASⅡ能增强5-FU对BEL-7402/FU的细胞毒作用,逆转耐药倍数分别为 1.49,1.81。0.08、0.16 mg/mL 的ASⅡ作用BEL-7402/FU细胞24 h后,能下调MDR1 mRNA和P-gp蛋白表达水平,提高细胞内Rhodamine123的荧光表达率。结论: ASⅡ能部分逆转肝癌多药耐药性,其机制可能与下调MDR1 mRNA表达及抑制P-gp的功能与表达有关。

Abstract: AIM: To investigate the effect of AstragalosideⅡ on the reversal of multidrug resistance in human hepatic cancer cells.METHODS: Susceptibility of chemotherapy drugs and relative reversal fold was evaluated by MTT. The mRNA level of MDR1 gene was detected by RT-PCR and the P-glycoprotein expression was detected by immunocytochemistry method. Intracellular Rhodamine123 accumulation was determined by flowcytometry.RESULTS: BEL-7402/FU cells showed resistance to three chemotherapy drugs 5-fluorouracil, Adriamycin and Mitomycin, their resistance index were 19.64, 1.98, 1.92. Astragaloside Ⅱ(0.04, 0.08 mg/mL) relative reversal fold were 1.49, 1.81 to 5-fluorouracil. Astragaloside Ⅱ(0.08 mg/mL, 0.16 mg/mL) could downregulate the expression of MDR1 mRNA and P-glycoprotein, increase the intracellular Rhodamine123 fluorescence.CONCLUSION: Astragaloside Ⅱ could reverse the drug resistance of Bel-7402/FU cells via regulating down the expression of MDR1 mRNA, inhibit the expression and function of P-glycoprotein.
