Disease relevance of Nppb

 

High impact information on Nppb

  • These animals showed 10- to 100-fold increase in plasma BNP concentration accompanied by elevated plasma cyclic GMP concentration, and had significantly lower blood pressure than their nontransgenic littermates [4].
  • The mouse BNP gene was organized into three exons and two introns [4].
  • In transgenic (Tg) mice that overexpress BNP in response to hindlimb ischemia, neovascularization with appropriate mural cell coating was accelerated without edema or bleeding, and impaired angiogenesis by the suppression of nitric oxide production was effectively rescued [5].
  • In response to ventricular pressure overload, focal fibrotic lesions are increased in size and number in Nppb(-/-) mice, whereas no focal fibrotic changes are found in wild-type littermates (Nppb(+/+) mice) [1].
  • The half life of [125I]ANP in the circulation of homozygotes lacking NPRC is two-thirds longer than in the wild type, although plasma levels of ANP and BNP in heterozygotes and homozygotes are close to the wild type [6].
 

Chemical compound and disease context of Nppb

  • These haemodynamic effects probably contribute to the side-effects of BNP in patients with acute CHF with a 27% incidence of hypotension and possibly to 22% worsening of renal function, defined as an increase in serum creatinine of 0.5 mg/dL, associated with a worse prognosis [7].
  • We therefore compared angiotensin (Ang) II-induced cardiac hypertrophy and fibrosis in BNP-transgenic (Tg) mice, in which circulating BNP levels were elevated by increased secretion from the liver, and their non-Tg littermates [8].
  • Left ventricular hypertrophy was observed on echocardiography (1.25+/-0.05 mm vs. 0.86+/-0.02 mm in cTnI-wt, P<0.01), associated with a significant 4-fold increase in RNA markers of hypertrophy, ANF and BNP [9].
  • Myocyte cross-sectional area, a measure of hypertrophy, was decreased by 30% in the NS-398 versus vehicle group, but there was no effect on BNP mRNA [10].
 

Biological context of Nppb

  • Studies using an in vitro organ culture of embryonic mouse tibias revealed that BNP increases the height of cartilaginous primordium directly, thereby stimulating the total longitudinal bone growth [2].
  • The ANP and BNP gene expressions are markedly augmented in ventricles of patients with a wide variety of cardiovascular diseases [11].
  • Such an autoregulatory pathway may represent an important physiological homeostatic mechanism and link the paracrine activity of NO and CNP with the endocrine functions of ANP and BNP in the regulation of vascular tone and blood pressure [12].
  • It has been demonstrated that the ANP and BNP genes are tightly linked on mouse chromosome 4 and on the distal short arm of human chromosome 1 [11].
  • By polymerase chain reaction, we isolated an approximately 11-kb human genomic DNA fragment containing the third exon of the BNP gene and the first and second exons of the ANP gene [11].

Other interactions of Nppb

  • Natriuretic peptides organize a family of three structurally related peptides: atrial natriuretic peptide, brain natriuretic peptide (BNP), and C-type natriuretic peptide [2].
  • The family of rGCs is rapidly expanding, and it is plausible that there might be additional, as yet undiscovered, rGCs whose function is to provide alternative signalling pathways for one or both of these peptides, particularly given the low affinity of NPRA for BNP [13].
  • In response to acute cardiac pressure overload induced by aortic constriction, massive fibrotic lesions were found in all the BNP-/- mice examined, accompanied by further increase of mRNA expression of TGF-beta3 and Col alpha1(I) [3].
  • CONCLUSIONS: Increased BNP-mRNA levels in hypertensive ANG-overexpressing mice and decreased BNP in hypotensive AT1-deficient animals suggest that this mRNA expression is blood pressure-dependent [24].
  • However, the observed alterations of fibrosis and the unchanged BNP in hypotensive ANG knockouts and impaired BNP-mRNA expression in normotensive AT2-deficient mice demonstrate a direct interaction of the RAS and NPS that is fibrosis- rather than blood pressure-dependent [24].
