Enhanced expression of endothelin-1 gene in resistance arteries in severe human essential hypertension

Abstract excerpt

BACKGROUND: Endothelins are potent vasoconstrictors, and may also act as mitogens and hypertrophic agents. Expression of a member of this family of peptides, endothelin-1, is enhanced in the endothelium of blood vessels of rats with severe forms of hypertension, even in the absence of elevated plasma endothelin levels. In some of these hypertensive models enhanced endothelin-1 gene expression may contribute to...
