Proadrenomedullin N-terminal 20 peptide (PAMP) immunoreactivity in vertebrate juxtaglomerular granular cells identified by both light and electron microscopy.
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...
متن کاملProadrenomedullin N-terminal 20 peptide inhibits aldosterone secretion of human adrenocortical and Conn's adenoma cells: comparison with adrenomedullin effect.
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...
متن کاملProadrenomedullin NH(2)-terminal 20 peptide (PAMP) and adrenomedullin bind to teratocarcinoma cells.
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...
متن کاملExpression of adrenomedullin and proadrenomedullin N-terminal 20 peptide in human and rat prostate.
Adrenomedullin (AM) and proadrenomedullin N-terminal 20 peptide (PAMP) are two recently discovered hypotensive peptides translated from the same message transcript (preproAM mRNA). In this article we report the presence of AM, PAMP, and their mRNA in human and rat prostate and of AM receptor mRNA in rat prostate. PreproAM mRNA was found in the epithelium of normal human and rat prostate glands ...
متن کاملThe effect of adrenomedullin and proadrenomedullin N- terminal 20 peptide on angiotensin II induced vascular smooth muscle cell proliferation
Objective(s): The study aimed to investigate the effects of adrenomedullin (ADM) and proadrenomedullin N- terminal 20 peptide (PAMP) on angiotensin II (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 w...
