• at 2 months, mice show complete rescue in hypertrophic growth seen in Tg(Myh6-Mapk14*)1Jmol animals
• rescue of the chamber enlargement and reduced fractional shortening is also observed
• interstitial cell fibrosis is significantly attenuated compare with Tg(Myh6-Mapk14*)1Jmol mice

mortality/aging
• most die by 8 months from lethal cardiomyopathy

cardiovascular system
• myocyte cross-sectional area is increased significantly by 4 months of age
• at 2 months, mice show significant increase in heart-to-body weight ratios that increase with age compared to controls
• before 2 months of age, mice exhibit concentric hypertrophic remodeling
• end-diastolic and end-systolic dimensions are significantly increased, with unchanged or decreased wall thicknesses suggesting cardiomyopathy
• end-diastolic and end-systolic dimensions are significantly increased, with unchanged or decreased wall thickness suggesting cardiomyopathy
• insterstitial cell fibrosis is observed by 4 months of age
• by 4 months, fractional shortening is significantly reduced
• diastolic dysfunction is reduced by 4 months of age
• left ventricular pressure gradient versus time (systolic function) is significantly reduced by 4 months of age
