The protein deacetylase Sirtuin-1 (Sirt1) is involved in the cardiac hypertrophic responses and cardiac embryo morphogenesis. However, the physiological function of Sirt1 deficiency in the postnatal development of the heart remains to be characterized. The aim of this study was to investigate the relevance of Sirt1 in the development and function of the myocardium by using complementary techniques, such as gene expression, immunoblotting, immunohistochemistry, histological and electron microscopy examinations, and in vivo cardiac magnetic resonance imaging (MRI).
