Local modulation of the natriuretic peptide system in the rat remnant kidney.

modulation of the natriuretic peptide system in the rat remnant kidney

BACKGROUND: The natriuretic peptide (NP) system plays a central role in the renal adaptations to acute volume expansion. However, the modulation of the NP system in chronic renal insufficiency (CRI) remains to be elucidated. In the present study, we evaluated cardiac haemodynamics, plasma type-B natriuretic peptide (BNP) levels and the expression of natriuretic peptide receptor A (NPR-A) and NPR-C in the renal ...

Ventricular BNP gene expression in acute cardiac overload

INTRODUCTION: B-type natriuretic peptide (BNP) plasma levels have important diagnostic and prognostic implications in heart failure (HF). Recently, aside from its natriuretic effect, antiproliferative and antifibrotic actions of BNP on the cardiovascular system have been described. Under physiological conditions the atria are the main source of this peptide, while its ventricular expression is still controversi...
