Activation effect of quercetin on chloride channel activities in mouse ileum and colon. (A) Activation of CFTR and CaCC-mediated Cl− current in freshly isolated mouse ileum by different concentrations of quercetin. (B) Activation of CFTR and CaCC-mediated Cl− current in colonic epithelia by different concentrations of quercetin. The corresponding histogram of each trace compares the Isc obtained from different concentrations of quercetin. (C) Inhibition of CFTR-mediated Cl− current by indicated CaCCinh-A01 in mouse ileum. (D) Inhibition of CFTR chloride channel activity by CFTRinh-172 (100 μM).
