Figure 2From: Zosuquidar restores drug sensitivity in P-glycoprotein expressing acute myeloid leukemia (AML) P-gp activity in K562, HL60 and their variant resistant cell lines. P-gp activity was measured by the uptake of DiOC2(3) and rhodamine in either presence or absence of either zosuquidar (grey) or CsA (black). Two examples histograms K562 versus K562/Dox and HL60 versus HL60/DNR are presented in this figure.Back to article page
