Endothelin-3 caused transient forearm vasodilatation at this dose, whereas endothelin-1 showed only a nonsignificant trend toward causing early vasodilatation. 2011-01-26 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 mediates its effects through ET A R and ET B R, both of which are G … Endothelin is a newly described polypeptide derived from endothelial cells. The effects of porcine endothelin on the pulmonary vascular bed and systemic vascular bed were investigated in the anesth 1. The mechanism underlying the vasoconstriction induced by endothelin‐1 (ET‐1) was investigated by measuring the intracellular concentration of Ca2+ ([Ca2+]i), isometric force and phosphorylation of the myosin light chain (MLC) in endothelium‐denuded unskinned and beta‐escin‐treated skinned smooth muscle from resistance vessels of the rabbit mesentery.

105-114. 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 ).
