Figure 6: ABC-G2 (BCRP) inhibitory effects of enriched fraction of Elephantopus scaber (ES-DCM) in human epithelial cancer cells. A549 (a) and MCF-7 (b) cells were incubated with mitoxantrone (MXR) in Dulbecco's modified eagle medium with 2% Fetal bovine serum for 30 min at 37°C (accumulation phase), after which excess dye was washed and cells were re-incubated with vehicle control (dimethyl sulfoxide), fumitremorgin C (FTC), and ES-DCM for 60 min at 37°C (efflux phase). The mean cellular MXR fluorescence in the efflux phase was analyzed by flow cytometry. Error bars represent ± standard error of the mean; n = 3, ***P < 0.001
