Atrial natriuretic peptide (ANP) inhibits its own secretion via ANP(A) receptors: altered effect in experimental hypertension.
Three atrial natriuretic peptide (ANP) receptors, ANP(A), ANP(B), and ANP(C), have been identified in the heart, suggesting that natriuretic peptides may have direct effects on cardiac function. To characterize the possible role of atrial natriuretic peptide (ANP) in the regulation of its own secretion, we studied here the effects of ANP (greater affinity for ANP(A) than for ANP(B) receptors) a...
متن کاملA splice variant of the guanylyl cyclase-A receptor interferes with atrial natriuretic peptide (ANP) signaling
Background Activation of the homodimeric transmembrane guanylyl cyclase-A (GC-A) receptor upon binding of its extracellular ligands, atrial (ANP) and B-type (BNP) natriuretic peptides, leads to cyclic GMP formation in many types of cells. This NP/GC-A pathway has a critical role in the endocrine regulation of arterial blood pressure and volume and in the local counter-regulation of cardiac hype...
متن کاملGuanylyl cyclase receptors mediate cardiopulmonary vagal reflex actions of ANP.
Atrial natriuretic peptide (ANP) potentiates vagal cardiopulmonary reflexes due to chemosensory (Bezold-Jarisch [B-J] reflex) or mechanosensory (ramp baroreflex) activation. The ANP receptor mediating these actions is unknown. We examined the role of particulate guanylyl-cyclase (pGC) receptors in ANP-induced enhancement of cardiopulmonary vagal reflexes. Cardiopulmonary baroreceptor reflex fun...
متن کاملAllotopic antagonism of the non-peptide atrial natriuretic peptide (ANP) antagonist HS-142-1 on natriuretic peptide receptor NPR-A.
The microbial polysaccharide HS-142-1 has been documented as an antagonist of natriuretic peptides. It inhibits activation and peptide binding to both guanylate receptors natriuretic peptide receptor (NPR)-A and NPR-B, but has no effect on the non-cyclase receptor NPR-C. At first sight the effect of HS-142-1 on peptide binding appears to be surmountable, suggesting that it might be competitive ...
متن کاملCharacterization of atrial-natriuretic-factor-receptor-coupled membrane guanylate cyclase from rat and mouse testes.
Studies with isolated adrenal cells and mouse testicular cells have supported a mediatory role of cyclic GMP in ANF (atrial natriuretic factor)-dependent steroidogenic signal transduction. This concept has been strengthened by the purification and biochemical characterization of a 180 kDa protein, which appears to contain both ANF receptor and guanylate cyclase activities, from rat adrenocortic...
