    The role of endothelin-1 in the development or the maintenance of salt hypertension induced in young (4-week-old) or adult (12-week-old) Dahl rats was compared. Acute ET(A) receptor blockade lowered BP in both age groups of salt hypertensive Dahl rats more than in rats fed a low-salt diet (but without any age-dependent difference). Chronic ET(A) receptor blockade strongly attenuated the development of salt hypertension and cardiac hypertrophy in adult rats, but it had no significant effects on salt hypertension in young animals. Pronounced BP reduction induced in adult salt hypertensive rats by chronic ambrisentan treatment was attributed to attenuated sympathetic BP component, without changes in nitric oxide (NO)-dependent BP regulation. Thus ET(A) receptor-mediated ET-1 effects play an important role in salt hypertension of adult but not young Dahl rats
