mortality/aging
• about 50 to 60% of embryos die before implantation or early postimplantation

cardiovascular system
• homozygotes undergoing transverse aortic banding to induce concentric cardiac hypertrophy show a smaller increase in cardiac fibrosis and reduced expression of a variety of extracellular matrix proteins and fibrogenic cytokines at 3 weeks after banding than wild-type, however hypertrophic responses are not impaired and cardiac dimension and contractile function are preserved
• exhibit about a 20% increase in heart rate after induction of pressure overload
