1 To this end the renin system in male Sprague Dawley rats was stimulated by unilateral renal artery clipping (0.2 mm clip), by furosemide (60 mg/kg per diem) or isoproterenol (160 microg/kg per diem), and by ingestion of a low-salt diet (0.02%), or was suppressed by setting a contralateral renal artery clip (0.2-mm clip) or by ingestion of a high-salt diet (4%). Isoproterenol renin Rattus norvegicus
2 Renin gene expression was stimulated four- to fivefold by renal artery clipping and isoproterenol infusion, two- to three-fold by furosemide and a low-salt diet, and about four-fold by losartan. Isoproterenol renin Rattus norvegicus
3 Additional treatment with losartan potentiated the stimulatory effects of a low-salt diet, of furosemide and of isoproterenol infusion on renin gene expression, whilst there was no significant additional effect of losartan on renin gene expression in clipped kidneys. Isoproterenol renin Rattus norvegicus
