Endothelins as autocrine regulators of tumor cell growth

Anna Bagnato, Kevin J. Catt

Research output: Contribution to journalArticlepeer-review


Endothelin 1 (ET-1) is produced by several types of human cancer cells and has been proposed to participate in tumor development or progression by exerting autocrine or paracrine actions on neoplastic cells and their surrounding stromal cells. Recently, an ET-1-mediated autocrine loop has been implicated in the growth of ovarian tumor cells. The co-expression of ET-1 and ET(A) receptors, with consequent activation of growth signaling pathways in human ovarian carcinoma cells, constitutes a mechanism for the autocrine regulation of tumor cell growth. Such findings also provide a basis for further investigation of the role of tyrosine phosphorylation in ET-1- regulated growth responses in ovarian tumor cells. The overexpression of ET- 1 and its receptor in cancer cells may serve as a tumor marker, and could provide potential targets for therapy.
