Fig. 2From: Anti-cancer effects of Rhizoma Curcumae against doxorubicin-resistant breast cancer cellsEstablishment and characterization of the doxorubicin (DOX)-resistant MCF-7 breast cancer cell line. Doxorubicin-resistant MCF-7 breast cancer cell line (MCF-7/DOXR) was established by a stepwise exposure of MCF-7 cells to increasing concentrations of doxorubicin (DOX). Cells were treated with DOX for 48 h. a Cell viability was tested using MTT assay, represented by percentage of control. b Protein expression was evaluated using western blotting assay. c The expression alterations of P-gp were confirmed by FITC-P-gp antibody staining using flow cytometryBack to article page
