Figure 6

(A) Sensitive CCRF-CEM and multidrug-resistant ABCB1 (MDR1)-overexpressing CEM/ADR5000 cells; (B) sensitive HL60 and multidrug-resistant ABCC1 (MRP1)-overexpressing HL60/AR cells; and (C) sensitive MDA-MB-231-pcDNA and multidrug-resistant ABCG2 (BCRP)-transduced MDA-MB-231-BCRP cells. Values represent the mean (± SEM) of three independent experiments.
