  • endothelin/sarafotoxin family
  • CATEGORY signaling hormone growth factor
    basic FUNCTION
  • endothelin 1, vaso-constrictor/pressor peptide
  • phospholipase C activator, playing a role in airways, including bronchoconstriction, airway mucus secretion, cell proliferation, and inflammation
  • playing a role on epithelial ion transport in airways
  • playing a direct role in HDL metabolism
  • endothelial cell-derived vasoconstrictor and growth factor
  • potent vasoactive peptide that is synthesized and released by the vascular endothelium and is a marker of endothelial function
  • induces cortical neurite elongation through the endothelin A receptor
  • may exert its vasoconstrictive effects in part by targeting KCNK3
  • induces mRNA and protein secretion of CCL2 and IL6, forming an autocrine signaling pathway that stimulates collagen accumulation in the extracellular matrix
  • increases collagen deposition in the extracellular matrix by inducing an autocrine signaling loop involving secretion of CCL2 and IL6
  • increases CCL2 and IL6 mRNAs and peptide secretion in mesangial cells
  • role of EDN1 in linking TLR7 inflammatory signaling to subsequent fibrosis
  • TGFbeta-induced EDN1 expression in dermal fibroblasts and showed that the TGFB1-induced expression of profibrotic genes was dependent on EDN1
  • in part because it induces the unfolded protein response in pulmonary artery smooth muscle cells, triggers proinflammatory processes that likely contribute to vascular remodeling in pulmonary hypertension
  • BMPs act upstream and in parallel to EDN1 to promote ventral fates in the arches during early dorsal-ventral patterning
  • would act in a cooperative manner with EDN2, giving to the villus the straight enough to withstand mechanical stress
  • potent vasoconstrictor, the production of which is mainly catalyzed by endothelin-converting enzymes (
  • is a potent lymphangiogenic factor that relies on the interplay with hypoxic microenvironment and with VEGFA, VEGFC, and FIGF
  • induces positive inotropy (enhanced contractility) in cardiac muscle
  • EDN1 affects systolic Ca2+, and myofilament Ca2+ sensitivity and PRKCE is the upstream kinase involved in all of these intracellular regulatory processes
  • integral role for ectoderm-derived EDN1 in early arch morphogenesis, particularly in the intermediate domain (
  • essential role of endothelin 1 (EDN1) signaling through the endothelin receptor type A (EDNRA) in patterning the mandibular portion of the first pharyngeal arch
  • RETN and EDN1 have been reported to inhibit adipogenesis and regulate adipocyte insulin resistance, respectively
  • EDN1 activation of EDNRA signalled through ARF6, which is crucial for lipolysis
  • CELLULAR PROCESS cell life, proliferation/growth
    cell communication
    signaling signal transduction
    a component
  • components of the endothelin system, are EDN1, EDNRB and ECE1
    small molecule
  • interacting with CHGA (variation in expression of the CHGA gene influences endothelial EDN1 secretion, explained by a CHGA stimulus/EDN1 secretion coupling in endothelial cells)
  • EDNRB is involved in the regulation of the growth of and in the formation of functional vessels upon activation by EDN1
  • interacting with ZNF260 (ZNF260 is an obligatory effector of EDN1 signaling in cardiomyocytes)
  • interacting with IL6, and CCL2 (an autocrine signaling loop involving CCL2 and IL6 contributes to EDN1-induced collagen accumulation)
  • link between EDN1 and EDNRA and myelination during oligodendrocyte differentiation
  • decreases ABCG1 possibly due to the enhancement of the proteosome/calpain pathway-dependent degradation of ABCG1
  • PRKCA, PRKCB, stimulates collecting duct EDN1 synthesis via transcriptional activation of the EDN1 promoter (
  • GDF2 induced EDN1 release is involved in both inhibition of endothelial cell migration and promotion of tubule formation
  • mediates the autocrine effect of endothelin-1 (EDN1) on endothelial cell survival
  • CDC42 plays an important role in trophoblast migration and is obligatory for EDN1 action
  • ARRB1 is a nuclear transcriptional regulator of EDN1-induced CTNNB1 signaling
  • EDN1 regulates neural crest deployment and fate to form great vessels through DLX5/DLX6-independent mechanisms
  • EDN1 stimulates RETN gene expression
  • ARF6 plays a role in EDN1 promoted endothelial cell migration, and acts upstream of ERK in EDN1-induced lipolysis
  • NR4A1 is a novel negative regulator of EDN1 expression in vascular ECs through an inhibitory interaction with the JUN pathway
  • sarcolemmal and nuclear membrane CACNA1E in vascular smooth muscle cells are involved in EDN1 modulation of vascular tone in physiology and pathology
