Effects of insulin and IGF-I on basal, NPPB-sensitive, and benzamil-sensitive Isc. Histogram illustrating the basal Isc and the absolute decrease in Isc after apical addition of 5 μM benzamil and subsequent apical addition of 100 μM NPPB to the cell monolayers. Cells were grown in standard media (SM, n = 12, N = 4) for 1 wk and replaced with serum-free media (SFM, n = 9, N = 4) in the absence or presence of 850 nM insulin (n = 23, N = 9) or 1.3 nM IGF-I (n = 7, N = 4) for 4 d.
