Inhibition of epithelial Na+ transport by atriopeptin, protein kinase c, and pertussis toxin.


We have recently shown the selective inhibition of an amiloride-sensitive, conductive pathway for Na+ by atrial natriuretic peptide and 8-bromoguanosine 3',5'-cyclic monophosphate (8-BrcGMP) in the renal epithelial cell line, LLC-PK1. Using 22Na+ fluxes, we further investigated the modulation of Na+ transport by atrial natriuretic peptide and by agents that… (More)
