摘要: 目的: 探讨槲皮素对白血病细胞多药耐药逆转的影响。方法: 以人白血病细胞系K562 及耐药细胞系K562 A02(耐阿霉素) 为实验对象, 采用MTT 法检测细胞毒性, 流式细胞仪检测P-gp 表达水平。结果: 10 μmol·L-1槲皮素对细胞毒性和P-gp 的表达无影响, 20、40 μmol·L-1槲皮素能明显增强化疗药物对细胞的毒性, 降低P-gp 表达的水平。结论: 槲皮素能逆转K562 A02 细胞耐药性。

Abstract: AIM: To explore the effect of quercetin on resistance reversal and its mechanism. METHODS: Human erythroleukemic cell line K562 and its doxorubicin- resistant counterpart K562 A02 were used in the study.Cytotoxicity was assessed by MTT assay.P-gp expression was measured with flow cytometry. RESULTS: Quercetin of 10μmol·L -1 had no effect on the multidrug resistance reversal and P-gp expression.However, quercetin of 20 μmol·L -1 could increase chemosensitivity of F562 A02 and decrease the P-gp expression. CONCLUSION: Quercetin can reverse drug-resistance of K562 A02 cell to Daunorubicin.
