The aim of the present study was to determine the relationship between the hypotensive effect of the atrial natriuretic peptide (ANP) and the nitric oxide (NO) pathway. N(G)-nitro-L-arginine methyl ester bolus (L-NAME, 1 mg/kg) reverted the decrease in mean arterial pressure induced by ANP administration (5 microg/kg bolus and 0.2 microg x kg(-1) x min(-1) infusion), and the injection of L-NAME...

Ventricular hypertrophy is characterized by augmentation of synthesis, storage, and release of atrial natriuretic peptide (ANP) from ventricular tissue, but the physiological stimulus for ANP release from ventricles is not known. We determined the effect of graded, passive myocardial stretch on ANP release in isolated, arrested, perfused heart preparations after removal of the atria in 13-20-mo...

Protein kinase-dependent and Ca2 -independent cAMP inhibition of ANP release in beating rabbit atria. Am J Physiol Regulatory Integrative Comp Physiol 282: R1477–R1489, 2002; 10.1152/ajpregu.00316.2001.—Regulation of atrial release of atrial natriuretic peptide (ANP) is coupled to changes i...

AVP and atrial natriuretic peptide (ANP) have opposite effects in the kidney. AVP induces antidiuresis by insertion of aquaporin-2 (AQP2) water channels into the plasma membrane of collecting duct principal cells. ANP acts as a diuretic factor. An ANP- and nitric oxide (NO)/soluble guanylate cyclase (sGC)-induced insertion of AQP2 into the plasma membrane is reported from different models. Howe...

Introduction To elucidate the expression of the atrial natriuretic polypeptide (ANP) gene in the ventricle of the human failing heart, we have measured ANP and ANP messenger RNA (ANPmRNA) levels in left ventricular aneurysm obtained at operation, biopsy specimens of left ventricles from dilated cardiomyopathy (DCM) and autopsy samples of old myocardial infarction (OMI) and DCM hearts, and compa...

A combined two established techniques, namely the Quality Function Deployment (QFD) and the Analytic Network Process (ANP) use in product development process. In this paper shows the how to use ANP decision making tool in QFD matrix. Combine the QFD and ANP method to determine the overall priorities of ECs. The ANP is a multi criteria decision-making method used to derive relative priority from...

Atrial natriuretic peptide (ANP)-C receptor activation has been shown to inhibit adenylyl cyclase (AC) activity as well as to stimulate phospholipase C (PLC) signaling pathways. The present studies were undertaken to investigate whether ANP-C receptor-mediated decreased cAMP levels contribute to the activation of PLC signaling. C-ANP(4-23) [des(Gln(18),Ser(19), Glu(20),Leu(21),Gly(22))ANP(4-23)...

Elevated plasma natriuretic peptide levels after AMI (acute myocardial infarction) are associated with adverse outcome. The aim of the present study was to examine the relationship of plasma N-ANP (N-terminal pro-atrial natriuretic peptide) and N-BNP (N-terminal pro-B-type natriuretic peptide) with mortality and heart failure following AMI. We studied 403 patients with AMI. Blood was sampled fo...

The atrial natriuretic peptide (ANP) is suggested to regulate inflammatory response by alteration of macrophage functions. The aim of this study was to investigate whether ANP influences production of TNF-alpha. TNF-alpha production in murine bone marrow-derived macrophages was induced by LPS, and TNF-alpha secretion (+/-ANP) was determined by L929 bioassay. ANP dose dependently (10-8-10-6 M) i...

Nephrotic syndrome is associated with resistance to the renal actions of atrial natriuretic peptide (ANP). We performed experiments in anesthetized, acutely nephrectomized rats 21-28 days after injection of adriamycin (7-8 mg/kg iv) or 9-14 days after injection of anti-Fx1A antiserum (5 ml/kg ip) (passive Heymann nephritis; PHN) to test whether extrarenal resistance also occurred. Proteinuria w...
