cardiovascular system
• medium expressing mice show greater pulmonary congestion measured by lung weight to tibia length compared to controls after 2 weeks of transverse aortic constriction
• 8-week old medium expressing transgenic mice show a 91% increase in heart weight normalized to tibia length compared to controls after 2 weeks of transverse aortic constriction
• medium expressing mice have enlarged hearts compared to controls after 2 weeks of transverse aortic constriction
• 8-week old medium expressing transgenic mice show a 91% increase in heart weight normalized to tibia length compared to controls after 2 weeks of transverse aortic constriction
• medium expressing mice show greater left ventricle dilation compared to controls after 2 weeks of transverse aortic constriction; mice show more dilation than wild-type and low expressing animals which display concentric hypertrophy
• medium expressing mice exhibit greater decompensation in ventricular performance compared to controls after 2 weeks of transverse aortic constriction
