Abstract | BACKGROUND: We recently reported that aldosterone-induced cellular senescence via an increase in p21, a cyclin-dependent kinase (CDK) inhibitor, in rat kidney and cultured human proximal tubular cells. In the present study, we investigated the contribution of aldosterone to the renal p21 expression and senescence during the development of angiotensin II (AngII)-induced hypertension. METHODS: Mice received 1% salt in drinking water and vehicle or AngII, and were divided into five groups: 1, vehicle; 2, AngII; 3, AngII+olmesartan; 4, AngII+eplerenone; and 5, AngII+hydralazine. RESULTS: CONCLUSION: These results suggest that aldosterone does not predominantly contribute to renal p21 expression and senescence during the development of AngII- salt hypertension, and that the increase in p21 in the kidney is not likely involved in the development of hypertension and albuminuria.
