Endothelin-1 (ET-1) is the most potent endogenous vasoconstrictor and is strongly implicated in the pathogenesis of hypertension and endothelial dysfunction. 3,85,86 ET-1 is produced by endothelial cells in response to stimuli, including VEGF, and its secretion is inhibited by NO, PGI 2, ANP, and epidermal growth factor (EGF). 85,87,88 ET-1

Endothelin-1 (ET-1) is a potent vasoconstrictor. Proendothelin-1 (pro-ET-1) and big-ET-1, which both can be cleaved into a small active 21-residue ET-1 by endothelial converting enzyme (ECZ), are both present within the arterial wall (Figure 13.1). Endothelin-1 (ET-1) is an extremely potent vasoconstrictor peptide originally isolated from endothelial cells. Its synthesis, mainly regulated at the gene transcription level, involves processing of a precursor by a furin-type proprotein convertase to an inactive intermediate, big ET-1. Endothelin-1 is the most powerful endogenous chemical affecting vascular tone across organ systems.

Quantitate human Endothelin 1 in plasma, serum, supernatant and urine. Sensitivity: 0.579 Endothelin 1 is an endothelium derived vasoconstrictive peptide produced in vascular endothelial cells. It is one of the three isoforms of endothelin, and a potent Endothelin 1, Human and Porcine, CAS 117399-94-7, is a 21-amino acid polypeptide with potent vasoconstrictive action. Activates phospholipase C in fibroblasts Endothelin. Endothelin-1 (ET1) is a 21–amino acid peptide secreted by vascular endothelial cells in response to stimuli, including pulsatile stretch, sheer Endothelin-receptor antagonists competitively bind to the endothelin-1 receptors EtA and EtB, causing reductions in pulmonary arterial pressure, pulmonary The endothelins comprise three structurally similar 21-amino acid peptides. Endothelin-1 and -2 activate two G-protein coupled receptors, ETA and ETB, with Endothelin-1, a potent endothelium-derived vasoconstrictor peptide, exerts a growth-promoting effect on vascular smooth muscle cells, implicating its pathogenic Endothelin 1 (ET-1) is a 21-amino-acid vasoactive peptide synthesized by many cell types.

The assay employs human serum-based standards to ensure the measurement of biologically reliable data. Big Endothelin-1 ELISA Assay Principle Endothelin is a potent vasoactive peptide occurring in three isotypes, ET-1, ET-2, and ET-3.

Endothelin-1 (ET-1) is a powerful vasoconstrictor peptide and regulator of blood flow that plays an important role in blood pressure (BP) elevation in some models of experimental hypertension such as DOCA-salt rat, DOCA-salt-treated spontaneously hypertensive rats (SHR), stroke-prone SHR, Dahl salt-sensitive rats, angiotensin II-infused rats, and one-kidney, one-clip Goldblatt rats Endothelin Biosynthesis. Endothelin (ET-1) is a 21 amino acid peptide that is produced by the vascular endothelium from a 39 amino acid precursor, big ET-1, through the actions of an endothelin converting enzyme (ECE) found on the endothelial cell membrane. Endothelins are endothelium-derived vasoconstrictor peptides (By similarity).

Endothelin-1 (ET-1), a peptide of 21 amino acid (aa) residues, is a pleiotropic molecule best known for its action as a potent vasoconstrictor (1). Originally isolated from porcine aortic endothelial cells, ET-1 is one of a family of three proteins encoded by distinct genes that also includes Endothelin-2 (ET-2) and Endothelin-3 (ET-3) (2, 3).
