mortality/aging
• between 2 and 20 weeks, mortality is greater than in wild-type mice
• over 40% of mice are dead by 20 weeks of age whereas all wild-type mice remain alive
|
• between 2 and 20 weeks, mortality is greater than in wild-type mice
|
cardiovascular system
• at 20 weeks, mice exhibit advanced chronic hepatic congestion unlike in wild-type mice
• mice exhibit liver with areas of central venous congestion unlike in wild-type mice
|
• mice exhibit heterogeneity in myocyte size with some vacuolization unlike in wild-type mice
|
• left ventricular end systolic and end diastolic dimensions are increased 33% and 18%, respectively, compared to in wild-type mice
|
• mice exhibit biventricular enlargement without an increase in wall thickness or increase in ventricular weight
|
• as early as 4 weeks, mice exhibit dilated cardiomyopathy in all four chambers of the heart unlike wild-type mice
• by 8 weeks, all mice exhibit dilated cardiomyopathy without inflammatory cell infiltration
|
• treatment with isoproterenol induces less of an increase in fractional shortening compared to in similarly treated wild-type mice
|
• left ventricular shortening fraction is decreased 35% compared to in wild-type mice
|
