Effect of 8-Br-cAMP and KT5720 on ICl(swell)
A, representative trace illustrating the inhibitory effect of 100 μm 8-Br-cAMP on ICl(swell). B, leak-subtracted current-voltage relationship of ICl(swell) evoked by 75 mm NaCl (•) and in the same hypotonic solution containing 100 μm 8- Br-cAMP (○). Each point is the mean ±s.e.m. of 6 cells. C, representative trace illustrating the increase of ICl(swell) induced by 1 μm KT5720. D, leak-subtracted current-voltage relationship of ICl(swell) evoked by 75 mm NaCl (•) and in the same hypotonic solution containing 1 μm KT5720 (○). Each point is the mean ±s.e.m. of 5 cells.
