Allgemeine Beschreibung
Big endothelin-1 is a 39 amino acid peptide, which is synthesized and secreted by vascular smooth muscle and endothelium cells. It is produced as an inactive enzyme, and is cleaved and activated by serine and aspartic proteases and metalloproteinases. Activated form is called ET-1, which is a potent vasoconstrictor. ET-1 is also produced by the action of endothelin converting enzyme (ECE) on big-ET-1. In guinea pigs, big-ET-1 causes the release of prostanoids and thromboxanes.
Anwendung
Big Endothelin 39 rat has been used for charting of a standard curve in the study of the role of ET-1 in ventricular dilatation.
Biochem./physiol. Wirkung
Precursor of Endothelin-1; vasoconstrictor activity appears to be due to its conversion to endothelin 1 by endothelin converting enzyme in the tissue.

Immunocytochemical localization of big endothelin-1 (big ET-1), ET-1, and ET receptor A and B (ET(A) and ET(B)), and gene expression of prepro ET-1 mRNA were examined on the rat liver vasculature. Immunoreactivities for big ET-1 and ET-1 were preferentially seen

Matrix metalloproteinase-2 (MMP-2, gelatinase A) and its tissue inhibitor (TIMP-2) are mainly known for their roles in the (patho)physiological remodeling of the vasculature, angiogenesis, tissue repair, tumor invasion, inflammation, and atherosclerotic plaque rupture. A mechanism of action of MMP-2 is

1. Changes in vascular permeability following intravenous injections of human big-endothelin-1 (big-ET-1) and endothelin-1 (ET-1) were measured by extravasation of Evans blue dye (EB, 20 mg kg-1) in selected tissues. 2. A low dose of big-ET-1 (40 pmol kg-1) failed

Left ventricular dilatation after myocardial infarction is associated with impaired ventricular function and heart failure and has important implications for survival. The purpose of this study was to investigate the role of endothelin-1 (ET-1) in ventricular dilatation and the effects

In porcine aortic endothelial cells, the 21-amino acid peptide endothelin-1 (ET-1) is formed from a 39-amino acid intermediate called "big endothelin-1" (big ET-1) by a putative ET-converting enzyme (ECE) that cleaves the 39-mer at the bond between Trp-21 and Val-22.
