Ibrutinib enhanced the effect of paclitaxel on the growth of an ABCC10-overexpressing HEK293/ABCC10 cell xenograft model in athymic nude mice. A, Images of excised HEK293/ABCC10 tumors tissues from different mice are shown on the 18th day after treatment (n = 7). B, Changes in tumor volume with time in ABCC10-overexpressing xenograft model are shown. C, Mean weight (n= 7) of the excised HEK293/ABCC10 tumors from the mice treated with vehicle, ibrutinib, paclitaxel, or the combination of ibrutinib and paclitaxel. Error bars, SD. *, P < 0.05 versus vehicle group; #, P < 0.05 versus the paclitaxel group. D, The average body weight before and after treatments.
