Regulation of endothelin-1 and mediator release from endothelial cells in culture and a characterisation of the receptor pathways involved

Cel



Endothelin-1 (ET-1), which is synthesised by endothelial cells is the most potent vasoconstrictor and pressor peptide yet described. Increases in the production of ET-1 are associated with a growing list of cardiovascular dysfunctions. Thus, an understanding of the biology of ET-1 may well help in the understanding of many cardiovascular disease processes. Although the effects of exogenous ET-1 on different vascular systems have been partially characterised, the mechanisms involved in the synthesis, release and metabolism of the endogenous ET-1 are poorly understood. This is largely due to the lack of simple to use models in which responses to endogenously produced ET-1 may be investigated. Within the course of the proposed project a multi-disciplined approach will be used to understand how ET-1 is regulated. Thus, isolated cells and vascular preparations in vitro will be used to understand how ET 1 is released and acts, and whole animal experiments will be used to show how individual vascular beds respond to both exogenous and endogenous ET-1. In addition, biochemical assays will be used to measure mediator release and molecular biology to investigate changes at the enzyme level. The information gained from this proposed project will further our understanding on how ET-1 interacts with other endothelial-derived mediators and may well provide the impetus for new approaches in the use of ET-1 receptor antagonists and synthesis inhibitors.
