cardiovascular system
|
• ubiquitin puncta are present in about 2.4% of cardiomyocytes
• cardiomyocytes exhibit deposition of protein aggregates that disrupt myofibrillar structure and these protein aggregates occur in prefibrotic hearts
• large vacuoles and a reduction in fiber diameter are often seen in ubiquitin aggregate-containing cardiomyocytes
• mitochondria and sarcoplasmic reticulum are abnormal in cardiomyocytes
|
|
• abnormal mitochondria in cardiomyocytes
|
|
• myofiber disarray in the ventricular myocardium of hearts
|
|
• heart is smaller than in single homozygous Aarssti mice
|
|
• hearts exhibit a slight, but significant, reduction in the thickness of the left ventricular posterior wall
|
|
• extensive cardiac fibrosis is seen at 4 and 10 months of age
• interstitial and perivascular fibrosis in the left and right ventricular walls and in the interventricular septum
|
|
• in the left and right ventricular walls and in the interventricular septum
|
|
• less systolic thickening of the left ventricle, indicating myocardial dysfunction
|
|
• ventricular output, as measured by the ejection fraction and fractional shortening of the left ventricle, are reduced
|
|
• ejection fraction and fractional shortening of the left ventricle are reduced
• however, ventricular arrhythmias are not seen
|
|
• cardiomyocytes exhibit multilamellar bodies indicative of impaired lysosomal degradation
|
cellular
|
• abnormal mitochondria in cardiomyocytes
|
|
• in the left and right ventricular walls and in the interventricular septum
|
growth/size/body
|
• decreased body weight at P21 but not P14
