Resistance to doxorubicin (DOX) is mainly due to the effect of P-glycoprotein encoded by the multidrug resistance (MDR) gene. Cepharanthine (CEP) has been shown to circumvent multidrug resistance in P-glycoprotein-expressing cell lines. In the present study, we investigated the augmentation of DOX sensitivity by CEP using an MTT assay, and assessed the correlation between DOX sensitivity and P-glycoprotein expression by flow cytometry, in highly purified fresh human tumor cells obtained from 73 cancer patients. DOX sensitivity was decreased in proportion to P-glycoprotein expression. The cytotoxicity of DOX was increased by CEP in tumor cells possessing low DOX P-glycoprotein sensitivity. Moreover, there was a significant correlation between the effect of Doxorubicin CEP on cytotoxicity and P-glycoprotein expression. Thus, CEP might be able Cepharanthine to circumvent DOX resistance in cancer patients.
