In summary, we have seen that endothelins are potent cardiovascular and renal regulatory peptides. Cardiovascular regulation by endothelin requires complex spatial and temporal regulation of endothelin gene expression and the coordinated interplay of numerous signaling pathways. Although the precise physiologic role for endothelin peptides in the cardiovascular and renal systems remains uncertain, two general models can be proposed, as follows. (1) Endothelin appears to act as an autocrine or paracrine hormone involved in long-term (hours to days) regulation of cardiovascular and renal function in normal physiology. Similar regulation occurs in response to other cardiovascular hormones such as angiotensin II, atrial natriuretic peptides, and catecholamines. In this respect it is noteworthy that endothelin also interacts with other hormonal systems that affect cardiovascular status, such as renin-aldosterone and atrial natriuretic peptide (see references 9, 161, 162, and 213-217). (2) Endothelin might also function as a proinflammatory peptide, being locally produced at sites of vascular damage and injury. The fact that endothelin secretion is stimulated by cytokines, growth factors, and transforming growth factor beta is consistent with this role. In addition, the mitogenic actions of endothelin could contribute to vascular remodeling in the inflammatory response. A similar, defensive role has been proposed for other regulatory peptides. Endothelin has also been implicated in the pathogenesis of numerous disorders such as hypertension (see references 28, 56, 168, 184, and 224 through 226), cerebral and myocardial vasospasm (see references 180, 223, and 227 through 233), acute renal failure, and cyclosporine nephrotoxicity. It is clear that the development of specific ECE inhibitors and endothelin receptor antagonists will enable definitive experiments addressing the role of endothelin in normal physiology and the putative role of endothelin in the development of hypertension and other cardiovascular disorders. Further identification and biochemical analysis of signaling networks evoked by endothelin, in conjunction with physiologic studies, should provide a detailed understanding of the complex biologic events regulated by endothelin peptides.
