Fig. 5. Selonsertib increased the intracellular [3H]-drug accumulation in cancer cells overexpressing ABCB1 and ABCG2.
(A) The effect of selonsertib on the accumulation of [3H]-paclitaxel in KB-3–1 and KB-C2 cell lines. (B) The effect of selonsertib on the accumulation of [3H]-paclitaxel in SW620 and SW620/Ad300 cell lines. (C) The effect of selonsertib on the accumulation of [3H]-mitoxantrone in NCI-H460 and NCI-H460/MX20 cell lines. (D) The effect of selonsertib on the accumulation of [3H]-mitoxantrone in S1 and S1-M1–80 cell lines. Verapamil (10 μM) and Ko 143 (10 μM) were used as positive controls for ABCB1 and ABCG2 overexpressing cells respectively. Data are mean, representative of three independent experiments. *p < 0.05, compared with control group. Selo, selonsertib; Vera, verapamil and Ko, Ko 143.
