Data Sheet

Background: Endothelin is a hormone produced predominantly by endothelial cells that have been recognized to play a significant role in the development of several cardiovascular disease states. ETB is mainly expressed in vascular endothelial and and epithelial tissues as well as by smooth muscle cells. ETB activation of smooth muscle cells results in vasoconstriction, whereas ETB activation on vascular endothelium causes vasodilation through the release of nitric oxide. ETB has also been found to lower blood pressure through natriuresis and diuresis, and to release prostaglandins. In the kidney, ETB also serves to clear endothelins from circulation by receptor-mediated endocytosis and subsequent lysosomal degradation. Mutations in the ETB gene have been linked to Waardenburg syndrome, as well as Hirschsprung disease type 2.
