mortality/aging
|
• mice show a more rapid mortality beginning at 10 weeks of age, with a median survival of 40 weeks
• mice die of sudden cardiac death without signs of prior illness
|
cardiovascular system
|
• loss of cardiac muscle in the right ventricular wall
|
|
• accumulation of fat droplets is only seen at sites of fibrosis in all hearts
|
|
• E16.5 and E18.5 hearts show severe disruption of the myocardial structure, with a variegated pattern of muscle damage
• loss of myocardial integrity that includes the interventricular septum is seen by E18.5
|
|
• interaction between the desmin-containing intermediate filaments is disrupted in desmosomes
|
|
• intercalated discs of cardiomyocytes show abnormal distribution of proteins
• 12 week old mice show irregularly shaped intercalated discs with widened gaps between the two-electron dense desmosomal plates
|
|
• myocardial disarray and increased intercellular spaces between myocytes in myocardial regions
|
|
• E16.5 and E18.5 hearts show erosion and thinning of the right ventricular wall
|
|
• both the left and right ventricles are dilated in 12 week old mice
|
|
• right ventricular dilation in E16.5 hearts
|
|
• increase in end-systolic volumes and decrease in ventricular ejection fraction at 12 weeks of age
• contraction of the ventricles is minimal as indicated by minimal change in the cross-sectional area between end-diastolic and end-systolic frames at midpapillary level
|
|
• increase in end-systolic volumes and decrease in stroke volume, ventricular ejection fraction, and cardiac output at 12 weeks of age
|
|
• young adult mice show frequent spontaneous runs of nonsustained ventricular tachycardia
|
|
• young adult mice show frequent multifocal ventricular ectopy
|
|
• heart exhibit features of human arrhythmogenic right ventricular cardiomyopathy
