Endothelin-1 functions as an endogenous chemical affecting vascular tone across the organs in the body. All three endothelins are classified as having vascular homeostasis functions. They are involved in cardiovascular function, electrolyte homeostasis, and many other mechanisms on a cellular level.


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 

Recent evidence from both human and animal models shows involvement of endothelin in diabetes, retinal circulation, and optic neuropathies. Increased Endothelin-1 (ET-1), a member of endothelin peptide family is released by many different tissues including uterine smooth muscle. ET-1 acts through ETA and ETB receptors and is implicated in a Se hela listan på de.wikipedia.org Endothelin-1 (ET-1), a vasoconstrictive and pro-inflammatory peptide, is associated with several cardiovascular risk factors and outcomes. We aimed to investigate the association of plasma ET-1 levels and renal function among young and healthy adults. Figure 1: Components of the endothelin system.

Endothelin-1 critically influences cardiac function via superoxide-MMP9 cascade Catherine K. Hathawaya, Ruriko Granta, John R. Hagamana, Sylvia Hillera, Feng Lia, Longquan Xua, Albert S. Changa, Endothelin is a potent vasoactive peptide occurring in three isotypes, ET-1, ET-2, and ET-3. Through its two main receptors, endothelin A and endothelin B, it is responsible for a variety of physiological functions, primarily blood flow control.

Mediates its action by association with G proteins that activate a phosphatidylinositol-calcium second messenger system. The rank order of binding affinities for ET-A is: ET1 > ET2 >> ET3. ET1 is released constitutively from endothelial cells and regulates vascular function.

The endothelin receptors, ET A and ET B, have differential tissue and functional distributions.

Diseases associated with EDN1 include Question Mark Ears, Isolated and Auriculocondylar Syndrome 3. Among its related pathways are Prostaglandin Synthesis and Regulation and Physiological and Pathological Hypertrophy of the Heart. Endothelin-1 (ET-1) is a potent vasoconstrictor peptide released by the endothelium that contributes to the regulation of vascular tone.

Se hela listan på cvphysiology.com Endothelin-1 has control over water and sodium excretion in the kidneys. The endothelin system in the brain provides regulation of both cardiorespiratory functions and hormone release. Endothelin-1 also has a strong influence on the development of hypertension and heart failure. Title: Endothelin-1: The Yin and Yang on Vascular Function VOLUME: 13 ISSUE: 14 Author(s):Flora L. Marasciulo, Monica Montagnani and Maria A. Potenza Affiliation:Department of Pharmacology and Human Physiology, Medical School, University of Bari, Policlinico - P.zza G. Cesare, 1, 70124 Bari - Italy. In patients with renal or cardiac failure, renal function may be endangered by elevated plasma concentrations of the vasoconstrictor endothelin-1 (ET-1). To mimic effects of pathologically increased plasma ET-1, we gave intravenous ET-1 in healthy subjects and examined whether simultaneous infusion of the ET A -receptor antagonist VML 588 would prevent the effects of ET-1 on the kidney. Calcium-regulated non-receptor proline-rich tyrosine kinase 2 (Pyk2) is a critical mediator of endothelin-1 (ET-1) signaling in human glomerular mesangial cells (GMC).
