mortality/aging
• mean and maximum life span is reduced by 59% and 55%, respectively, compared to in wild-type mice
• mice develop kyphosis and loss of subcutaneous fat earlier in life than wild-type mice

cardiovascular system
• mice exhibit an increase in cardiac myocyte cross-sectional area and increased variability in cross-sectional areas compared to in wild-type mice
• at 7 to 11 months, mice exhibit increased heart weight to body weight compared to wild-type mice that becomes more pronounced with age

• at 9 months of age

immune system

• in the myocardium at 2 months of age

cellular
