These experiments were designed to elucidate which of two second messengers (cyclic 3', 5' adenosine monophosphate [c-AMP]; intracellular calcium [Cai]) was more closely related to the renin secretory process. The rat renal cortical slice preparation was used. Agents which previously were shown to inhibit basal renin secretion by increasing Cai(ouabain, vanadate, angiotensin II, antidiuretic hormone, and 60 mM K) antagonized and/or blocked isoproterenol-stimulated secretion, which is thought to be mediated by adenylate cyclase activation and increased levels of c-AMP. The stimulatory effect of dibutyryl c-AMP was antagonized and/or blocked by the same agents which antagonized and/or blocked isoproterenol-stimulated secretion. Thus, the inhibitory effects of these agents on isoproterenol-stimulated secretion cannot be explained by a Ca-induced decrease in c-AMP production. Secretory rate was stimulated by a potent phosphodiesterase inhibitor (3-isobutyl-l-methylxanthine). A combination of this and dibutyryl c-AMP produced even greater stimulation. Ouabain blocked the stimulatory effect of this combination. These results are not consistent with an invariant direct relationship between c-AMP and renin secretory rate, but are consistent with an inverse relationship between Caiand renin secretion. Further, they are consistent with the sypothesis that in isoproterenol-stimulated renin secretion, c-AMP is the second and Caithe third or the final messenger.
