General description

Research area: Cell Signaling

Endothelin 1 (ET-1) is a peptide hormone located in the endothelial cells and belongs to the endothelin family. It is a derivative of pre-pro-ET-1 which is later converted to mature ET-1 by a group of ET-converting enzymes (ECEs), endopeptidases, chymases, and non-ECE metalloproteinases. The EDN1 gene is mapped to the human chromosome at 6p24.1.

Application

Endothelin 1, Human and Porcine - CAS 117399-94-7 – Calbiochem 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

Biochem/physiol Actions

Endothelin 1 (ET-1) acts as a mediator of paracrine and autocrine functions. The production of ET-1 is upregulated under pathophysiological conditions and is produced in several types of cells such as cardiac myocytes, vascular smooth muscle cells, and inflammatory cells like leukocytes and macrophages. ET-1 is a potent vasoconstrictor peptide that is stimulated by risk factors in several types of cells for cardiovascular diseases. It is involved in many biological effects such as pro-inflammatory actions, platelet activation, stimulation of free radicals, and mitogenic and proliferative effects. ET-1 plays a role in pulmonary physiology, neurological function, autoimmune disorders, transportation of electrolytes and fluids, and cancer. It is an essential component for the development of embryonic neural crest-derived tissues. ET-1 is involved in osteogenesis by promoting osteoblast proliferation by activating Wnt signaling pathway.
