title: Influence of salt loading on the cardiac and renal preproendothelin-1 mRNA expression in stroke-prone spontaneously hypertensive rats.
abstract: Endothelin-1 is a potent vasoactive peptide which may play a role in the regulation of vascular resistance through its autocrine/paracrine effects. We have investigated the influence of salt loading on the renal and cardiac production of endothelin-1 in stroke prone spontaneously hypertensive rats, a classical model of hypertension. The results show that the dietary salt intake did not change systolic blood pressure nor the renal expression of the preproendothelin-1 mRNA but increased cardiac expression of the endothelin-1 gene transcript and a concomitant ventricular hypertrophy.
