title: Atrial natriuretic peptide inhibits protein phosphorylation stimulated by angiotensin II in bovine adrenal glomerulosa cells.
abstract: Bovine adrenal glomerulosa cells were incubated with 32PO4 and either angiotensin II, atrial natriuretic peptide, or both. Solubilized cells were subjected to one-dimensional gel electrophoresis. Autoradiography and scintillation counting of gels showed that angiotensin increased labeling of one band, with an apparent molecular weight of 17,600. Atrial natriuretic peptide inhibited the angiotensin effect. Together with earlier results, this observation suggests that atrial natriuretic peptide affects aldosteronogenesis at the level of protein phosphorylation, but not by altering angiotensin receptors, calcium fluxes or phosphoinositide metabolism.
