Four natriuretic peptides (ANP, BNP, VNP and CNP) coexist in the sturgeon: identification of BNP in fish lineage.
The natriuretic peptide (NP) family is composed of three members: atrial, brain/ventricular and C-type NPs (ANP, BNP/VNP and CNP respectively) in tetrapods and teleostean fish, but only CNP in elasmobranch fish. In order to trace the process of divergence of the NP family in early vertebrate evolution, we attempted to detect NPs in the primitive ray-finned fish, the sturgeon (Acipenser transmon...
متن کاملDiversified cardiovascular actions of six homologous natriuretic peptides (ANP, BNP, VNP, CNP1, CNP3, and CNP4) in conscious eels.
The natriuretic peptide (NP) family consists of seven paralogs [atrial NP (ANP), brain NP (BNP), ventricular NP (VNP), and C-type NP 1-4 (CNP1-4)] in teleosts, but relative biological activity of the seven NPs has not been comprehensively examined using homologous peptides. In this study, we newly identified CNP3 and CNP4 in eels to use homologous peptides, but the CNP2 gene may have been silen...
متن کاملResponses of cardiac natriuretic peptides after paroxysmal supraventricular tachycardia: ANP surges faster than BNP and CNP.
Atrial natriuretic peptide (ANP) secretion increases after 30 min of paroxysmal supraventricular tachycardia (PSVT). Whether this phenomenon also applies to brain or C-type natriuretic peptides (BNP or CNP) remains unknown. Blood samples of 18 patients (41 ± 11 yr old; 4 men) with symptomatic PSVT and normal left ventricular systolic function (ejection fraction 65 ± 6%) were collected from the ...
متن کاملAtrial natriuretic peptide and C-type natriuretic peptide in spontaneously hypertensive rats and their vasorelaxing actions in vitro.
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...
متن کاملThe natriuretic peptide system in eels: a key endocrine system for euryhalinity?
The natriuretic peptide system of a euryhaline teleost, the Japanese eel (Anguilla japonica), consists of three types of hormones [atrial natriuretic peptide (ANP), ventricular natriuretic peptide (VNP), and C-type natriuretic peptide (CNP)] and four types of receptors [natriuretic peptide receptors (NPR)-A, -B, -C, and -D]. Although ANP is recognized as a volume-regulating hormone that extrude...
