To evaluate of hesperidin to overcome resistance of doxorubicin in MCF-7 resistant doxorubicin cells (MCF-7/Dox) in cytotoxicity apoptosis and P-glycoprotein (Pgp) expression in combination with doxorubicin.
The cytotoxic properties, 50% inhibition concentration (IC50) and its combination with doxorubicin in MCF-7 cell lines resistant to doxorubicin (MCF-7/Dox) cells were determined using MTT assay. Apoptosis induction was examined by double staining assay using ethidium bromide-acridine orange. Immunocytochemistry assay was performed to determine the level and localization of Pgp.
Single treatment of hesperidin showed cytotoxic activity on MCF-7/Dox cells with IC50 value of 11 µmol/L. Thus, combination treatment from hesperidin and doxorubicin showed addictive and antagonist effect (CI>1.0). Hesperidin did not increase the apoptotic induction, but decreased the Pgp expressions level when combined with doxorubicin in low concentration.
Hesperidin has cytotoxic effect on MCF-7/Dox cells with IC50 of 11 µmol/L. Hesperidin did not increased the apoptotic induction combined with doxorubicin. Co-chemotherapy application of doxorubicin and hesperidin on MCF-7/Dox cells showed synergism effect through inhibition of Pgp expression.
评估橙皮苷与阿霉素联合使用时,对阿霉素耐药的MCF-7细胞(MCF-7/Dox)克服阿霉素耐药性、细胞毒性、凋亡及P-糖蛋白(Pgp)表达的影响。
采用MTT法测定橙皮苷在阿霉素耐药的MCF-7细胞系(MCF-7/Dox)中的细胞毒性、50%抑制浓度(IC50)及其与阿霉素联合使用时的情况。通过溴化乙锭-吖啶橙双重染色法检测凋亡诱导情况。采用免疫细胞化学分析法测定Pgp的水平和定位。
橙皮苷单药处理对MCF-7/Dox细胞显示出细胞毒性活性,IC50值为11μmol/L。因此,橙皮苷与阿霉素联合处理显示出相加和拮抗作用(CI>1.0)。橙皮苷与低浓度阿霉素联合使用时,未增加凋亡诱导,但降低了Pgp表达水平。
橙皮苷对MCF-7/Dox细胞具有细胞毒性作用,IC50为11μmol/L。橙皮苷与阿霉素联合使用时未增加凋亡诱导。阿霉素和橙皮苷联合化疗应用于MCF-7/Dox细胞时,通过抑制Pgp表达显示出协同作用。
