BACKGROUND Plasma concentrations of the peptides midregional proadrenomedullin (MR-proADM), midregional proatrial natriuretic peptide (MR-proANP), and C-terminal endothelin-1 precursor fragment (CT-proET-1) are increased in various cardiovascular conditions. However, there is limited information about the association and comparative performance of these peptides in peripheral arterial disease (...

the aim of the study was to evaluate the clinical usefulness of n-terminal pro-brain natriuretic peptide (nt-pro bnp) and nitric oxide (no) with echocardiography (gold standard test) in diagnosis of canine cardiomyopathy. out of 374 cases, 82 cases showing cardiovascular abnormalities including 16 cases of cardiomyopathy were further selected for standardization of biomarkers. significant (p

The mechanism of proadrenomedullin N-terminal 20 peptide (PAMP)-induced inhibition of catecholamine release from adrenergic nerve was investigated in nerve growth factor-treated PC12 cells that have differentiated characteristics somewhat similar to noradrenergic neurons. The effect of PAMP on the excitability of these cells was investigated with the use of perforated whole-cell clamp. PAMP hyp...

The gene for adrenomedullin (AM), a multifunctional peptide hormone, is expressed in mammalian renal tissue and has been shown to stimulate renin release. The exact cell source of this peptide and its gene-related partner, proadrenomedullin N-terminal 20 peptide (PAMP), in kidney is still uncertain. In the present study we have identified PAMP-immunoreactive cells in the kidney of different mam...

Proadrenomedullin NH(2-)terminal 20 peptide (PAMP) and adrenomedullin (ADM) bind to teratocarcinoma cells. The effects of PAMP and ADM on teratocarcinoma cells were investigated. (125)I-PAMP bound to PA1 cells with moderate affinity (K(d) = 110 nM) to a single class of sites (B(max) = 110 000/cell). Specific (125)I-PAMP binding was inhibited by PAMP (IC(50) of 100 nM) but not ADM, calcitonin ge...

Adrenomedullin (ADM) and proadrenomedullin N-terminal 20 peptide (PAMP) are two vasoactive peptides, which are highly expressed in human adrenal gland. Autoradiography showed the presence of abundant [125I]ADM and [125I]PAMP binding sites in both the outer cortex and medulla of human adrenals. ADM, but not PAMP binding was completely displaced by the specific CGRP1 receptor antagonist CGRP(8-37...

OBJECTIVES The study aimed to investigate the effects of adrenomedullin (ADM) and proadrenomedullin N- terminal 20 peptide (PAMP) on angiotensin (AngII)-stimulated proliferation in vascular smooth muscle cells (VSMCs). MATERIALS AND METHODS Thoracic aorta was obtained from Wistar rats and VSMCs were isolated from aorta tissues and then cultured. In vitro cultured VSMCs were stimulated with An...
