Endothelin 1
Lua error in Module:Infobox_gene at line 33: attempt to index field 'wikibase' (a nil value). Endothelin 1 (ET-1), also known as preproendothelin-1 (PPET1), is a protein that in humans is encoded by the EDN1 gene. The protein encoded by this gene is proteolytically processed to release a secreted peptide termed endothelin 1. This peptide is a potent vasoconstrictor and is produced by vascular endothelial cells. Endothelin 1 is one of three isoforms of human endothelin.
Preproendothelin is precursor of the peptide ET-1. Endothelial cells convert preproendothelin to proendothelin and subsequently to mature endothelin, which the cells release.[1]
Endothelin-1 receptor antagonists (Bosentan) are used in the treatment of pulmonary hypertension. Inhibition of these receptors prevents pulmonary vasculature constriction and thus decreases pulmonary vascular resistance.
