Coexpression of endothelin-converting enzyme-1 and endothelin-1 in different stages of human atherosclerosis.
BACKGROUND Endothelin-converting enzyme (ECE)-1 activates endothelin-1 (ET-1) and may thus contribute to the regulation of vascular tone and cell growth during atherosclerosis. METHODS AND RESULTS To evaluate ECE-1 immunoreactivity concerning big ET-1/ET-1, we performed qualitative and quantitative immunohistochemistry in normal internal mammary arteries (n=10), in coronary arteries with adap...
متن کاملGene expression of endothelin-1, endothelin-converting enzyme-1, and endothelin receptors in human epididymis.
We have previously reported the presence of endothelin-1 (ET-1) and its receptors in the human testis. In the present study we extended our investigations to human epididymis. The rationale of our study originated from the fact that sperm appear to be immotile during their transit through the epididymis. Hence, it is conceivable that specific factors, unknown to date, are present in this organ,...
متن کاملLocalization of endothelin-converting enzyme-1 in human kidney.
The distribution of endothelin-converting enzyme-1 (ECE-1) mRNA and protein was investigated in human kidney excised because of renal tumors. ECE-1 immunoreactivity was detected by immunohistochemistry throughout the different areas of the kidney in the vascular and tubular structures. In the cortex, ECE-1 immunostaining was present in the endothelial surface of arcuate and interlobular arterie...
متن کاملExpression of endothelin-1, endothelin-converting enzyme, and endothelin receptors in chronic heart failure.
BACKGROUND Elevated plasma levels of endothelin (ET)-1 have been reported in association with heart diseases, including heart failure. Furthermore, it has been suggested that ET-1 acts as a local autocrine/paracrine factor with biological activities such as vasoconstriction, mitogenesis, and inotropic effects on the heart. This study investigated alterations of ET-1, ET receptor, and endothelin...
متن کاملConstitutive phosphorylation of human endothelin-converting enzyme-1 isoforms.
To investigate the phosphorylation of human endothelin-converting enzyme-1 (hECE-1) and identify potential residues involved, both in vivo and in vitro phosphorylation labeling assays of hECE-1 isoforms were performed in combination with site-directed mutagenesis and mass spectrometric analyses. Initial studies found that endogenous hECE-1 was constitutively phosphorylated in a primary endothel...
