PhA efflux assay: concentration-dependent inhibition of ABCG2-mediated PhA efflux by telmisartan (A,B), candesartan cilexetil (C,D), losartan (E,F), and irbesartan (G,H) in HEK293-Tet-On cells transiently transfected with ABCG2 WT or ABCG2 variants (F489L and R482G), respectively. Data are shown as mean ± SD (n = 4–16). P < 0.05 vs. WT. Representative flow cytometric plots of genotype-specific telmisartan- (B), candesartan cilexetil- (D), losartan- (F), and irbesartan (H)-related inhibition of ABCG2-mediated PhA efflux.
