Endothelin-converting enzyme-1 (ECE-1) cleaves big endothelins, as well as bradykinin and beta-amyloid peptide. Several isoforms of ECE-1 (a-d) have been identified to date; they differ only in their NH(2) terminus but share the catalytic domain located in the COOH-terminal end. Using quantitative PCR, we found ECE-1d to be the most abundant type in several endothelial cells (EC) types. In addi...

Potassium (K) and sodium (Na) coexist on the soil exchange complex and soil solution. Both cations may exert antagonistic or synergistic effects on mutual absorption and translocation within plants, particularly under saline and saline-sodic field conditions. This study investigated the role of K in alleviating the adverse effects of Na on wheat [Triticum aestivum (L), Iquilab-91] grown at two ...

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, ...

Endothelin-1 (ET-1) is involved in the pathogenesis of a number of diseases, including wound healing. In cirrhosis, the wounding response of the liver, circulating ET-1 levels are elevated; moreover, ET-1 has potent effects on hepatic stellate cells, the key effectors of cirrhosis. In this study, we have examined the regulatory role of ECE-1, a critical enzyme involved in ET-1 synthesis, in the...

BACKGROUND The purpose of the present study was to retrospectively evaluate the effects of extracapsular extension (ECE) on the benefits of post-mastectomy radiation therapy (PMRT) for groups of patients with varying numbers of positive axillary nodes (1-3, 4-9 and ≥10 positive axillary nodes). METHODS A total of 1220 axillary node-positive patients who had received mastectomy were involved i...

BACKGROUND Recent studies have identified a polymorphism in the endothelin-converting enzyme (ECE)-1b promoter (-338C/A) that is strongly associated with hypertension in women. The polymorphism is located in a consensus binding sequence for the E2F family of transcription factors. E2F proteins are crucially involved in cell-cycle regulation, but their roles in cardiovascular function are poorly...

Endothelin-converting enzyme-1c (ECE-1c) is a membrane metalloprotease involved in endothelin-1 synthesis, which has been shown in vitro to have a role in breast, ovary and prostate cancer cell invasion. N-terminal end of ECE-1c displays three putative phosphorylation sites for the protein kinase CK2. We studied whether CK2 phosphorylates N-terminal end of ECE-1c as well as whether this has a r...

The vasoconstrictive peptide endothelin-1 (ET-1) is expressed in human epidermis at the gene and protein levels and plays an important role in stimulating pigmentation via its increased secretion by keratinocytes following ultraviolet B (UVB) irradiation. However, one or more biological mechanisms underlying the secretion of ET-1 by keratinocytes in human skin have never been evaluated. In mamm...
