N |
• mice show normal blood pressure and no apparent differences in heart morphology or function at baseline
|
• mice show attenuation of isoproterenol (a beta-adrenoreceptor agonist)-induced cardiac hypertrophy, with mice showing lower diastolic interventricular septal thickness, systolic interventricular septal thickness, diastolic and systolic left ventricular posterior wall, ratios of heart weight/body weight and heart weight/tibia length, attenuated hypertrophic myocardial area and cardiomyocyte area, greatly decreased interstitial and perivascular fibrosis, and reduced expression of cardiac hypertrophy-related genes than in wild-type mice
• mice show attenuation of pressure overload-induced cardiac hypertrophy, with mice subjected to transverse aortic constriction showing reduced left ventricular wall thickness, heart weight/body weight ratio, heart weight/tibia length ratio, cardiomyocyte size, and perivascular and interstitial fibrosis and alleviation of the ejection fraction and fractional shortening seen in wild-type mice
• however, mice with ISO-induced or pressure overload-induced cardiac hypertrophy show no difference from wild-type mice in the increase in capillary and arteriolar density
