BACKGROUND The atrial natriuretic peptide (ANP) family is a complex system consisting of at least three polypeptides and at least three types of receptor. Each peptide interacts with different types of receptor at varying degrees of affinity. To determine if natriuretic peptide levels influence natriuretic peptide receptor expression and regulation, we examined the expression of guanylyl cyclas...

Ventricular concentrations of atrial, brain (BNP) and C-type natriuretic peptide are enhanced in congestive heart failure (CHF). Natriuretic peptide receptors are present on ventricular myocytes and stimulate guanosine 3',5'-cyclic monophosphate (cGMP) production. cGMP has been demonstrated to affect myocyte function in vitro. Thus we hypothesized that the intracardiac natriuretic peptide syste...

BACKGROUND On trigeminal ganglion neurons, pain-sensing P2X3 receptors are constitutively inhibited by brain natriuretic peptide via its natriuretic peptide receptor-A. This inhibition is associated with increased P2X3 serine phosphorylation and receptor redistribution to non-lipid raft membrane compartments. The natriuretic peptide receptor-A antagonist anantin reverses these effects. We studi...

Natriuretic peptides are cyclized peptides produced by cardiovascular and neural tissues. These peptides inhibit various secretory responses such as the release of renin, aldosterone and autonomic neurotransmitters. This report tests the hypothesis that atrial natriuretic peptide reduces dopamine efflux from an adrenergic cell line, rat pheochromocytoma cells, by suppressing intracellular calci...

Background While it has long been know that phosphorylation of the kinase homology domain is a key regulatory mechanism of natriuretic peptide receptors, no biochemical proof for individual phosphorylation sites has been reported. Here, we describe biochemical verification of previously identified phosphorylation sites in both natriuretic peptide receptor A (NPR-A) and natriuretic peptide recep...

Natriuretic peptides (NPs), such as atrial natriuretic peptide (ANP), C-type natriuretic peptide (CNP), and adrenomedullin (ADM), are endogenous vasodilators acting via specific receptors. This study addressed the question of how pulmonary artery (PA) responses to these peptides and the gene expression of their receptors are modulated in pulmonary hypertension rat models exposed to chronic hypo...

acute dyspnea is a common cause of hospitalization in emergency departments (ed).distinguishing the cardiac causes of acute dyspnea from pulmonary ones is a major challenge for responsible physicians in eds. this study compares the characteristics of bedside ultrasonography with serum level of blood natriuretic peptide (bnp) in this regard. methods: this diagnostic accuracy study compares bedsi...

Metabolic Actions Could Confound Advantageous Effects of Combined Angiotensin II Receptor and Neprilysin Inhibition To the Editor: Dual angiotensin II receptor and neprilysin inhibition with LCZ696 provides additive blood pressure lowering in hypertensive patients, likely because of the well-characterized cardiovascular and renal natriuretic peptide actions.1 However, increased natriuretic pept...

PURPOSE The natriuretic peptide (NP) family includes atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP), and C-type natriuretic peptide (CNP). Natriuretic peptides are known to inhibit vascular cell growth and regulate vessel tone. There is also much evidence to suggest they modulate vascular permeability and angiogenesis, as well as regulating aqueous humor production in the eye...

The occurrence and development of gastric cancer are regulated by many factors result from the joint action factors. Studies have shown that ANP, NPRA, Cx43 play a vital role in proliferation migration cancer. This article reviews relationship between Atrial natriuretic peptide (ANP), receptor A (NPRA), Connexin43 (Cx43) with review aims to provide an effective reference value for scientific re...
