Endothelin-1 (human, porcine)

The Uses of Endothelin-1 (human, porcine)

Endothelin 1 has been used for coating wells in polystyrene ELISA plates. Potent agonist for ETA and ETB endothelia receptors. Induces the production of hypoxia-inducible factor 1α, and, thus, the production of VEGF.

What are the applications of Application

Endothelin-1 (human, porcine) has been used:
to study its effects on the production of erythropoietin under normoxia and carbon monoxide-induced hypoxia in rat models.
as a protein kinase C (PKC) agonist to study its effects on the phosphorylation of myofilament proteins in rat myocytes.
to induce a hypertrophic-like state to study its effects on contraction pressure in normal and mutated human induced pluripotent stem cells (hiPSC)-derived cardiomyocytes.
in vitro hydrolysis products of macroendothelin-1, a precursor of endothelin-1, and their pharmacodynamic properties in rabbits.
as a receptor for endothelin-1 and its role in G protein-mediated signal transduction Research.

Biological Functions

Endothelins are a family of vasoactive peptides secreted by endothelial cells. The three major endothelin peptides are all composed of 21 amino acids. Endothelins are the most potent vasoconstrictors known. Contraction of vascular smooth muscle in response to endothelin is associated with an increase in intracellular calcium. Increases in endothelin levels have been reported in patients with vasospastic, hypoxic, and ischemic diseases.The two identified isoforms of endothelin receptors have differing affinity for the three endothelin peptides. Selective and nonselective endothelin receptor antagonists are in development for potential use in the treatment of hypertension and other disorders associated with increased vascular resistance.

Biological Activity

Endothelin 1 (human, porcine) is an endogenous potent vasoconstrictor peptide that is an agonist at ETA and ETB receptors. Modulates vascular tone. Endothelin-1 (ET-1) is a potent vasoconstrictor peptide isolated from porcine endothelial cells. ET-1 is widely present at binding sites in blood vessels, heart, kidneys, adrenal glands, lungs, and brain, and its distribution is similar to endothelial cells.

Biochem/physiol Actions

Potent agonist for ETA and ETB endothelin receptors. Induces the production of hypoxia-inducible factor 1α, and, thus, the production of VEGF.
