The endothelins comprise three structurally similar 21-amino acid peptides. Endothelin-1 and -2 activate two G-protein coupled receptors, ETA and ETB, with equal affinity, whereas endothelin-3 has a lower affinity for the ETA subtype. Genes encoding the peptides are present only among vertebrates. The ligand-receptor signaling pathway is a vertebrate innovation and may reflect the evolution of

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. Secretion of endothelin-1 from the vascular endothelium signals vasoconstriction and influences local cellular growth and survival. Endothelin-1 (ET-1) is synthesized and secreted by activated endothelial cells, and is a peptide with potent vasoconstrictor activity. It is a marker for activated or dysfunctional endothelial cells. This peptide is one of the three isopeptides belonging to the endothelin family.

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

Results: Fourteen membranes were included in the analysis, nine from eyes with proliferative diabetic retinopathy and five idiopathic membranes. Flatmount diabetic membranes showed co-localization of endothelin-1 with S100A4 and CD31. Endothelin-1 is not only the most potent vasoconstrictor yet identified, 7 but it has also been shown to stimulate the proliferation of smooth-muscle cells, 8-10 and in vivo it may act in concert Endothelin-1 (ET-1) is the most potent vasoconstrictive agent currently identified, and it was originally isolated and characterized from the culture media of aortic endothelial cells. Two other isoforms, named endothelin-2 (ET-2) and endothelin-3 (ET-3), were subsequently identified, along with structural homologues isolated from the venom of Actractapis engaddensis known as the sarafotoxins. Endothelin-1. More A 21-amino acid peptide produced in a variety of tissues including endothelial and vascular smooth-muscle cells, neurons and astrocytes in the central nervous system, and endometrial cells. It acts as a modulator of vasomotor tone, cell proliferation, and hormone production.
