cardiovascular system
• in response to thoracic aortic banding (TAB), mutant animals show almost no cardiomyocyte hypertrophy or fibrosis
• left ventricular diameter increases during systole
• in mice >6 months of age, cardiac function declines
• in response to TAB, null animals display a blunted hypertrophic response
• slight reduction in contractility compared to wild-type at 2 months of age
• in response to thoracic aortic banding (TAB), contractility is reduced
