Endothelin 1 (ET-1), also known as preproendothelin-1 (PPET1), is a potent vasoconstrictor peptide produced by vascular endothelial cells,^[5] as well as by cells in the heart (affecting contractility) and kidney (affecting sodium handling).^[6] The protein encoded by this gene – EDN1 – is proteolytically processed to release endothelin 1. Endothelin 1 is one of three isoforms of human endothelin.

Sources

Preproendothelin is precursor of the peptide ET-1. Endothelial cells convert preproendothelin to proendothelin and subsequently to mature endothelin, which the cells release.^[5]^[7]

Clinical significance

Patients with salt-sensitive hypertension have higher plasma ET-1.^[6] Endothelin-1 receptor antagonists (Bosentan) are used in the treatment of pulmonary hypertension.^[5] Use of these antagonists prevents pulmonary arterial constriction and thus inhibits pulmonary hypertension.^[5]

As of 2020, the role of endothelin-1 in affecting lipid metabolism and insulin resistance in obesity mechanisms was under clinical research.^[8]
