Quantitative real-time reverse-transcriptase polymerase chain reaction (RT-PCR) was conducted and expression was measured of myocardial atrial natriuretic peptide (ANP; A), brain natriuretic peptide (BNP; B), collagen I (C), and matrix metalloproteinase-9 (MMP-9; D), respectively (mRNA corrected for 36B4 mRNA level). The relative corrected values are shown for each group. Data are presented as means ± SEM. N = 8-10 for all groups.*P < 0.05 vs. sham group.
