BACKGROUND Pulmonary fibrosis has high rates of mortality and morbidity; however, no effective pharmacological therapy has been established. C-type natriuretic peptide (CNP), a member of the natriuretic peptide family, selectively binds to the transmembrane guanylyl cyclase (GC)-B receptor and exerts anti-inflammatory and anti-fibrotic effects in various organs through vascular endothelial cell...

BACKGROUND/AIMS C-type natriuretic peptide (CNP), the third member of the natriuretic peptide family, is considered to be involved in the regulation of vascular tone. Furthermore, the recent demonstration of CNP in human kidney and urine may indicate a role for CNP in fluid and electrolyte homeostasis. Therefore, the aim of the present study was to investigate the possible role of CNP in renal ...

The purpose of the present experiments was to define the role of C-type natriuretic peptide (CNP) in the regulation of atrial secretion of atrial natriuretic peptide (ANP) and atrial stroke volume. Experiments were performed in perfused beating and nonbeating quiescent atria, single atrial myocytes, and atrial membranes. CNP suppressed in a dose-related fashion the increase in atrial stroke vol...

We demonstrated endothelial production of C-type natriuretic peptide (CNP), the third member of the natriuretic peptide family, and its regulation by cytokines, including tumor necrosis factor-alpha (TNF alpha). We thus proposed that CNP can control vascular tone and growth as an endothelium-derived relaxing peptide. We also revealed the marked elevation of plasma CNP concentration in patients ...

Background: The use of C-type natriuretic peptide (CNP) combined with cysteamine during pre-in vitro maturation (IVM) can help establish an effective pre-IVM system. Aims: This study was designed to investigate the effects of CNP combined with cysteamine on meiotic maturation and developmental competence of bovine oocytes in vitro. Met...

Metal catalysts based on ligands containing proton-responsive sites have found widespread applications in the hydrogenation of polar unsaturated substrates. In this contribution, Ir complexes incorporating lutidine-derived CNP (C = N-heterocyclic carbene, NHC; P phosphine) pincer with two nonequivalent Brønsted acid/base been examined aldehydes. To end, Ir(CNP)H2Cl were synthesized steps from l...

Oligodendrocytes (OLs) extend arborized processes that are supported by microtubules (MTs) and microfilaments. Little is known about proteins that modulate and interact with the cytoskeleton during myelination. Several lines of evidence suggest a role for 2',3'-cyclic nucleotide 3'-phosphodiesterase (CNP) in mediating process formation in OLs. In this study, we report that tubulin is a major CN...

Changes in brain white matter are prominent features of the aging brain and include glial cell activation, disruption of myelin membranes with resultant reorganization of the molecular components of the node of Ranvier, and loss of myelinated fibers associated with inflammation and oxidative stress. In previous studies, overexpression of CNP, a key myelin protein, was implicated in age-related ...

OBJECTIVE Calcific aortic valve disease is associated with the differentiation of valvular interstitial cells (VICs) to myofibroblast and osteoblast-like cells, particularly in the fibrosa layer of the valve. Previous studies suggested that C-type natriuretic peptide (CNP) protects against calcific aortic valve disease to maintain homeostasis. We aimed to determine whether CNP inhibits VIC path...

The present study determined circulating concentrations of atrial natriuretic peptide (ANP) and C-type natriuretic peptide (CNP) in Wistar-Kyoto (WKY) rats and spontaneously hypertensive rats (SHR) and also investigated the vasorelaxing action of ANP and CNP on isolated contracted aorta. We also defined the vasorelaxing action of a novel and newly synthesized 27-amino acid chimera of ANP and CN...
