mortality/aging

premature death ( J:298603 )

• mice begin to die at 17 months of age, with a survival rate of about 70% at this time

cardiovascular system

abnormal myocardial fiber morphology ( J:298603 )

• decrease in average cross-sectional area of left ventricle myocytes

• shorter maximum diameter of cardiomyocytes

increased heart left ventricle size ( J:298603 )

• the left ventricle chamber is large

increased heart right ventricle size ( J:298603 )

• the right ventricle chamber is large

thin ventricular wall ( J:298603 )

• the left ventricle and right ventricle free walls are thinner

cardiac interstitial fibrosis ( J:298603 )

• mice show an increase in fibrosis in hearts, with hearts showing higher levels of type I and type II collagens

dilated cardiomyopathy ( J:298603 )

• heart weight to body weight ratio is increased and heart mass is increased in 18-month, but not 12-month, old mice
