Effect of ovariectomy and angiotensin II (AII)-induced hypertension on the expression of myosin heavy chain (MHC) isoforms in rat ventricular muscle. Top representative electrophoresis analysis of cardiac MHC (upper: α-MHC, lower: β-MHC) from left ventricular homogenate. Bottom percentage of α-MHC per total MHC of the heart from SHAM and OVX rats, with/without AII. Data are mean ± SE from 5 to 7 hearts of each group. *^,†Significantly different (P < 0.05) from SHAM and SHAM + AII group, respectively, using Student–Newman–Keuls test after ANOVA
