Effects of verapamil and BSO on the sensitivity of MRP1-expressing cells and their corresponding control cells to daunomycin. Effects of verapamil and BSO on the sensitivity of MRP1-expressing cells and their corresponding control cells to daunomycin. A and C. Cells were incubated with varying concentrations of daunomycin. B and D. Cells were incubated with varying concentrations of daunomycin in the presence of 10 µM buthionine sulfoximine (BSO) and 1 µM verapamil (VRP). Cell survival was determined by MTT assay according to the method described in Materials and Methods.
