Biological Activity

Endothelin 1 (human, porcine) is a potent endogenous peptide agonist at ETA and ETB receptors. Produces strong vasoconstriction and pressor responses. Competitive binding assay shows that Endothelin 1 reversibly binds to receptors (IC50 values are 0.12 nM and 0.15 nM at ETB and ETA receptors respectively). Potency is dependent on blood vessel type (EC50 ranges from 2.72 nM - 17.4 nM). Activates PLC (EC50 = 0.3 nM), increases production of PGE2 (EC50 = 12 nM) and induces intracellular calcium release in human ciliary muscle cells. Also upregulates leptin mRNA expression and secretion in adipocytes (EC50 = 8.8 nM).

Scientific Data

Multiplex Immunoassay cardiac hypertrophy assay View Larger

Pluripotent stem cell-derived cardiomyocytes secrete Pro-BNP in response to small molecule-induction of cardiac hypertrophy Cardiomyocytes were treated with the vasoconstrictor, ET-1 (Endothelin-1; Catalog # 1160), or one of two L-type calcium channel inhibitors, Doxorubicin (Catalog # 2252) or Verapamil (Catalog # 0654). Levels of the cardiac hypertrophy marker, Pro-Brain Natriuretic Peptide (Pro-BNP), were detected via Luminex® bead-based multiplex assay (Catalog # LXSAH). A substantial increase in Pro-BNP was detected in the medium of cardiomyocytes treated with ET-1, a known inducer of cardiac hypertrophy. Conversely, Doxorubicin and Verapamil decreased Pro-BNP secretion from cardiomyocytes.

ELISA ET1 differentiated cardiomyocytes concentration dependent effect on Pro-ANP View Larger

Differentiated cardiomyocytes respond physiologically to Endothelin-1 induced hypertrophy Cardiomyocytes differentiated from BG01V human embryonic stem cells were treated with Endothelin-1 (ET-1; Catalog # 1160) for 28 hours to induce cardiac hypertrophy. Levels of Pro-Atrial Natriuretic peptide (Pro-ANP) secretion, which is known to be elevated during cardiac hypertrophy, were assessed using ELISA (Catalog # DANP00). As expected, detection of Pro-ANP increased proportionally with the concentration of Endothelin-1 treatment.

Western Blot western blot and ELISA ANP expression in cardiomyocytes derived from iPSCs View Larger

Endothelin Induces Expression of Atrial Natriuretic Peptide in Cardiomyocytes Derived from iPSCs JOY6 human iPSCs were differentiated into beating cardiomyocytes. After 21 days of differentiation cardiomyocytes were treated with 5 nM of Endothelin-1 (ET-1; Catalog # 1160) for 25.5 hours to induce cardiac hypertrophy. The level of secreted Pro-Atrial Natriuretic peptide (Pro-ANP), which is known to be elevated during cardiac hypertrophy, was assessed using (A) Western Blot and (B) ELISA (Human NTProANP Quantikine® ELISA; Catalog # DANP00). As expected, detection of Pro-ANP was increased in Endothelin-1 treated cells.
