Endothelin-1 (ET-1) is an endothelium-derived vasoconstrictor peptide that contributes to basal vascular tone. Impairment of the vasoconstrictor response to ET-1 could result in hyperperfusion and subsequent microvascular damage.
Abstract : Angiotensin II (Ang II) and endothelin-1 (ET-1) induce strong vasoconstriction via activation of receptors on vascular smooth muscle cells. In this thesis
Bolus administration of endothelin-1 elicits long-lasting renal afferent arteriolar vasoconstriction, in contrast to transient constriction induced by angiotensin II. Vasoconstriction is generally evoked by myosin regulatory light chain (LC 20) phosphorylation at Ser19 by myosin light chain kinase (MLCK), which is enhanced by Rho-associated kinase Upregulation of endothelin ETB receptor-mediated vasoconstriction in rat coronary artery after organ culture. / Eskesen, K; Edvinsson, Lars..

First, endothelin-dependent vasoconstriction is maximal at 34 μU/ml of insulin , but blocking endothelin receptors does not reveal insulin-induced dilatation at that concentration . Second, maximal NO-dependent vasodilatation occurs at a concentration of insulin of 3.4 mU/ml ( Fig. 2 ), but NOS inhibition does not reveal insulin-induced vasoconstriction at that concentration ( Fig. 3 ).
Vasoconstriction (A) and vascular smooth muscle (VSM) Ca 2+ responses (B and C) to 1 nM endothelin (ET)-1 in pressurized mesenteric arteries from sham and intermittently hypoxic (IH) rats. VSM Ca 2+ was measured with fura-2 AM. tions, endothelin produces a predominant vasodilata- tion, whereas at high concentrations, a vasoconstric- tor response is seen (2). Endothelin interacts with a specific receptor on smooth muscle cells and induces an influx of Ca2+, which leads to vasoconstriction (3). In view of this profile of biologic action, it Change in forearm blood flow as measured by area under the curve (AUC) in response to endothelin-1 in diabetic ( ) and control ( ) subjects (mean and SEM).

2017-09-01 · Vasoconstrictors, including endothelin-1 (ET-1), inhibit myocyte BK channels, leading to contraction, but mechanisms involved are unclear. Recent evidence indicates that BKα is primarily plasma membrane localized, whereas the cellular location of β1 can be rapidly altered by Rab11A-positive recycling endosomes.

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.

Endothelins are implicated in vascular diseases of several organ systems, including the heart, lungs, kidneys, and brain. Intralobar bolus injections of porcine endothelin (100-1000 ng) produced a mild vasoconstrictor response in the pulmonary vascular bed. The pulmonary vasoconstrictor response to endothelin was not altered when pulmonary vasomotor tone was increased by infusion of U46619.
