Arginine vasopressin stimulation of chloride secretion in Madin-Darby canine renal epithelial layers.
Arginine vasopressin (AVP) at a concentration of 0.1 microM stimulates an inward short-circuit current (SCC) in voltage-clamped Madin-Darby canine kidney epithelial layers with a mean peak of 3.1 +/- 0.8 microA cm-2 (n = 6). The response to AVP is markedly attenuated when inward SCC is stimulated with forskolin or prostaglandin E1, in Cl(-)-free media and by the Cl(-)-transport inhibitors, bumetanide and 5-nitro-2-(3-phenylpropylamino)-benzoic acid, consistent with an AVP-stimulated basal to apical Cl- secretion. Endogenous release of prostaglandins may contribute to AVP stimulation of Cl- secretion.
