Figure 2

Cardiomyocyte size and expression of fetal-type cardiac genes. (a) Hematoxylin–eosin staining of transverse sections of the LV myocardium of DS/lean and DS/obese rats at 15 weeks of age. Scale bars, 50 μm. (b) Cross-sectional area of cardiac myocytes determined from sections similar to those in (a). (c–e) Quantitative real-time (RT) PCR analysis of atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP), and β-myosin heavy chain (β-MHC) mRNAs in the left ventricle of DS/lean and DS/obese rats at 15 weeks of age, respectively. The amount of each mRNA was normalized by that of 18S rRNA and then expressed relative to the mean value for DS/lean rats. Data in (b) through (e) are means±s.e.m. for surviving animals (n=10 and 14 for DS/lean and DS/obese rats, respectively). *P<0.05 vs. DS/lean rats.
