Regulation of C-type natriuretic peptide expression.

C-type natriuretic peptide (CNP) is a member of the small family of natriuretic peptides that also includes atrial natriuretic peptide (ANP) and brain, or B-type natriuretic peptide (BNP). Unlike them, it performs its major functions in an autocrine or paracrine manner. Those functions, mediated through binding to the membrane guanylyl cyclase natriuretic peptide receptor B (NPR-B), or by signa...

C-type natriuretic peptide and vascular remodeling.

N-terminal pro-C-type natriuretic peptide, but not C-type natriuretic peptide, is greatly elevated in the fetal circulation.

We have identified recently a new peptide, NT-proCNP(1-50) (N-terminal pro-C-type natriuretic peptide), in the circulation of humans and sheep. A previous report of an elevated fetal-maternal gradient in immunoreactive CNP raised the possibility that processing and metabolism of proCNP may differ in maternal and fetal tissues. We therefore collected matching peripheral maternal and umbilical co...

C-type natriuretic peptide upregulates vascular endothelin type B receptors.

Cultured rat vascular smooth muscle cells (VSMCs) possess receptors for potent vasoconstrictor endothelin-1 (ET-1) as well as potent vasodilator natriuretic peptides (atrial, brain, and C-type natriuretic peptides [ANP, BNP, and CNP, respectively]). However, little is known about molecular interactions between endothelin receptors and natriuretic peptides in VSMCs. To elucidate whether natriure...
