- Abstract
Objective 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. Methods The cytotoxic properties, 50% inhibition concentration (IC 50 ) 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. Results Single treatment of hesperidin showed cytotoxic activity on MCF-7/Dox cells with IC 50 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. Conclusions Hesperidin has cytotoxic effect on MCF-7/Dox cells with IC 50 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.
