mortality/aging
• 36% of mice die within a year after birth
|
cardiovascular system
• surviving mice gradually develop cardiac hypertrophy over duration of one year, with increased left ventricle mass/body weight ratio and left ventricular posterior wall end diastole
• however, no impairment in cardiac contractility is seen, indicating a compensatory stage of cardiac hypertrophy
• makers of cardiac disease are elevated
|
• mice exhibit a thickened left ventricle wall and smaller left ventricle cavity
|
• mice exhibit surviving mice gradually develop cardiac hypertrophy over duration of one year, with increased left ventricle mass/body weight ratio and left ventricular posterior wall end diastole
|
growth/size/body
• surviving mice gradually develop cardiac hypertrophy over duration of one year, with increased left ventricle mass/body weight ratio and left ventricular posterior wall end diastole
• however, no impairment in cardiac contractility is seen, indicating a compensatory stage of cardiac hypertrophy
