Background Natriuretic peptide receptors A (NPR-A) and B (NPR-B) are transmembrane guanylyl cyclases that regulate blood pressure, heart size and long bone growth. Unlike most cell surface receptors that are desensitized by direct phosphorylation, phosphorylation of natriuretic peptide receptors is essential for activation, and dephosphorylation causes their desensitization. While there are six...
We tested both relaxation and cGMP generation by atrial (ANP), brain (BNP), and C-type natriuretic peptide (CNP) in oxytocin-stimulated myometrium from near-term pregnant guinea pigs to investigate the ability and mechanism of natriuretic peptides to inhibit myometrial contractility. Myometrial strips were contracted by 10(-8) M oxytocin, and relaxation to the cumulative addition (10(-9)-10(-6)...
Of the four endogenous members of the natriuretic peptide family, only atrial natriuretic peptide has been demonstrated to have neuromodulatory effects. This study compares the neuromodulatory effects of atrial natriuretic peptide and a recently identified natriuretic peptide, C-type natriuretic peptide, in the rabbit isolated vas deferens. The ability of these peptides to alter cyclic nucleoti...
Correspondence to: Professor Paulo M Bettencourt, Unidade Cuidados Intermédios Medicina, Hospital S Joaõ, Alameda Hernani Monteiro, 4200 Porto, Portugal; pbettfer@ esoterica.pt _________________________ T he identification of natriuretic peptides led to an explosion of basic and clinical investigations to clarify their physiology, pathophysiologic role in heart failure, and clinical usefulness....
C-type natriuretic peptide (CNP) plays a critical role in endochondral ossification through guanylyl cyclase-B (GC-B), a natriuretic peptide receptor subtype. Cartilage-specific overexpression of CNP enhances skeletal growth and rescues the dwarfism in a transgenic achondroplasia model with constitutive active mutation of fibroblast growth factor receptor-3. For future clinical application, the...
OBJECTIVES Our aim was to design, synthesize and test in vivo and in vitro a new chimeric peptide that would combine the beneficial properties of 2 distinct natriuretic peptides with a biological profile that goes beyond native peptides. BACKGROUND Studies have established the beneficial vascular and antiproliferative properties of C-type natriuretic peptide (CNP). While lacking renal actions...
We tested the hypothesis that natriuretic peptide receptors (NPRs) that are coupled to cGMP production act in a similar way to nitric oxide (NO) by enhancing acetylcholine release and vagal-induced bradycardia. The effects of enzyme inhibitors and channel blockers on the action of atrial natriuretic peptide (ANP), brain-derived natriuretic peptide (BNP), and C-type natriuretic peptide (CNP) wer...
In the rat, activation of alpha2-adrenergic receptors in the anterior hypothalamic nucleus inhibits sympathetic nervous system activity. Furthermore, local release of atrial natriuretic peptide inhibits norepinephrine release in this nucleus, blocking local activation of alpha2-adrenergic receptors, and thereby contributes to NaCl-sensitive hypertension in spontaneously hypertensive rats. To fu...
