1 We investigated the regulation of the atrial natriuretic peptide and brain natriuretic peptide genes in a rat model of myocardial infarction induced by isoproterenol (IP rat) and in a rat model of cardiac hypertrophy induced by aorto-caval shunt (AC shunt rat). Isoproterenol natriuretic peptide B Rattus norvegicus
2 Brain natriuretic peptide (BNP) mRNA levels in atria were significantly higher in IP rats than in controls at 18 h after the administration of isoproterenol, but not significant increases were observed in atrial natriuretic peptide (ANP) mRNA expression levels at any time point examined. Isoproterenol natriuretic peptide B Rattus norvegicus
3 Brain natriuretic peptide (BNP) mRNA levels in atria were significantly higher in IP rats than in controls at 18 h after the administration of isoproterenol, but not significant increases were observed in atrial natriuretic peptide (ANP) mRNA expression levels at any time point examined. Isoproterenol natriuretic peptide B Rattus norvegicus
4 In the ventricles, the BNP mRNA levels peaked at 18 h after isoproterenol administration, whereas ANP mRNA levels gradually increased until 3 days after isoproterenol administration. Isoproterenol natriuretic peptide B Rattus norvegicus
