Effect of an antisense oligodeoxynucleotide to endothelin-converting enzyme-1c (ECE-1c) on ECE-1c mRNA, ECE-1 protein and endothelin-1 synthesis in bovine pulmonary artery smooth muscle cells.
Endothelin-1 (ET-1) is secreted from endothelial and vascular smooth muscle cells (VSMC) after intracellular hydrolysis of big ET-1 by endothelin converting enzyme (ECE). The metallopeptidase called ECE-1 is widely thought to be the physiological ECE, but unequivocal evidence of this role has yet to be provided. Endothelial cells express four isoforms of ECE-1 (ECE-1a, ECE-1b, ECE-1c, and ECE-1...
متن کاملDisruption of ECE-1 and ECE-2 reveals a role for endothelin-converting enzyme-2 in murine cardiac development.
Endothelin-converting enzyme-1 and -2 (ECE-1 and -2) are membrane-bound metalloproteases that can cleave biologically the inactive endothelin-1 (ET-1) precursor to form active ET-1 in vitro. We previously reported developmental defects in specific subsets of neural crest-derived tissues, including branchial arch-derived craniofacial structures, aortic arch arteries, and the cardiac outflow trac...
متن کاملEvidence for intracellular endothelin-converting enzyme-2 expression in cultured human vascular endothelial cells.
We have previously reported the intracellular localization of the endothelin-converting enzyme-1 (ECE-1) in human umbilical vein endothelial cells. In the present study, we provide the first immunocytochemical and biochemical evidence for the presence of ECE-2 in human cells. ECE activity was determined by conversion of exogenously added big endothelin-1 (big ET-1) to ET-1 in subcellular fracti...
متن کاملPalmitoylation of the three isoforms of human endothelin-converting enzyme-1.
Endothelin-converting enzyme-1 (ECE-1) is a membrane-bound metalloprotease that catalyses the conversion of inactive big endothelins into active endothelins. Here we have examined whether the three isoforms of human ECE-1 (ECE-1a, ECE-1b and ECE-1c) are modified by the covalent attachment of the fatty acid palmitate and have evaluated a potential functional role of this modification. To do this...
متن کاملRegulated expression of endothelin converting enzymes in glomerular endothelial cells.
Endothelin converting enzyme (ECE) constitutes a potential regulatory site for the production of active mature endothelins. Two cDNAs (ECE-1 and -2) encoding ECE have recently been cloned, but the regulation of the expression of these ECE has not been clarified. In the study presented here, an attempt was made to determine whether or not glomerular endothelial cells (GEN) express ECE-1 and -2, ...
