Role of ion channels and calcium on apical ATPe Isc. A Effect of chloride channel blockers NPPB (500 µM), glybenclamide (100 µM) and NFA (100 µM) and calcium activated potassium channel blocker TPeA (100 µM), on apical ATPe ISC responses. Values are mean ± SEM for at least 3 replicates. B Effect of thapsigargin on the apical ATPe ISC response in the presence and absence of amiloride. Values are mean ± SEM for at least 4 replicates
