(a) Uptake of vinblastine in KB3-1 expressing with wild-type human P-glycoprotein (KB3-His⁶¹, filled circles), mutant P-glycoprotein in which His⁶¹ was replaced with phenylalanine (KB3-Phe⁶¹, open squares) and serine (KB3-Ser⁶¹, filled squares), and transfected with transfection vector (KB3-Vec, open circles). (b) The ratios between the accumulations of vinblastine with and without cyclosporine A (CYA) and (c) PCB-126 (with/without CYA or PCB-126) in KB3-Vec (open columns), KB3-His⁶¹ (cross-hatched columns), KB3-Phe⁶¹ (hatched columns), and KB3-Ser⁶¹ (filled columns). $*$ , $P < .05$ compared to KB3-Vec. Means and SD of 4 experiments.
