mortality/aging
• despite normal atherogenic lesions and lipid serum levels, mice fed a high-fat, high-cholesterol diet exhibit increased mortality compared with similarly treated wild-type mice
• mice are less likely than wild-type mice to survive up to 55 weeks
• mortality between birth and weaning is increased compared to in wild-type mice
• fewer than expected mice are present from E11.5 to E16.5

neoplasm
• 9 of 20 mice develop internal neoplasms or tumors unlike wild-type mice
• some mice develop sarcomas including hemangiosarcoma and osteosarcoma unlike wild-type mice

cardiovascular system
• aortic smooth muscle cells exhibit delayed senescence in culture compared with wild-type cells
• aortic smooth muscle cells a 2-fold increase in proliferation compared with wild-type cells

cellular
• aortic smooth muscle cells a 2-fold increase in proliferation compared with wild-type cells
• embryonic fibroblasts exhibit a 3-fold increase in proliferation compared with wild-type cells
• aortic smooth muscle cells and embryonic fibroblasts exhibit delayed senescence compared with wild-type cells

growth/size/body
• when fed a standard diet, body weight is increase 17% by 30 weeks compared with wild-type mice

reproductive system
• one mouse develops metritis unlike wild-type mice

immune system

liver/biliary system

homeostasis/metabolism
N
• mice exhibit normal atherogenic lesions and lipid serum levels in response to a high-fat, high-cholesterol diet

hematopoietic system

muscle
• aortic smooth muscle cells exhibit delayed senescence in culture compared with wild-type cells
• aortic smooth muscle cells a 2-fold increase in proliferation compared with wild-type cells
