mortality/aging
• in female and male mice

growth/size/body
• whether fed normal chow or a high-fat diet, mice exhibit reduced lean mass gain beginning at 8 weeks
• at 30 weeks when fed normal chow
• exaggerated when mice are fed a high-fat diet
• at 14 weeks in male mice fed normal chow
• in mice fed a high-fat diet
• in female mice

homeostasis/metabolism
N
• whether fed normal chow or a high-fat diet, mice exhibit normal serum IGF1 and IGFBP3 levels
• in mice fed a high-fat diet
• when fed normal chow, cold-exposed mice exhibit lesser decrease in body temperature compared with wild-type mice
• fed or fasting at 4 weeks of age
• at 4 weeks of age in mice fed normal chow
• in mice fed a high-fat diet
• in mice when fed a high-fat diet
• whether fed normal chow or a high-fat diet
• whether fed normal chow or a high-fat diet
• whether fed normal chow or a high-fat diet
• however, respiratory exchange ratio and absolute energy expenditure are normal
• at 12 to 14 weeks of age in wild-type mice when fed a high-fat diet
• at 14 weeks of age in wild-type mice when fed a high-fat diet
• mice fed a high-fat diet fail to exhibit an increase in liver triglyceride levels compared with wild-type mice

adipose tissue
• visceral white adipose tissue in female mice
• when fed normal chow (beginning at 12 weeks) and more so when fed a high-fat diet (beginning at 8 weeks) due to fewer adult adipocytes
• paler than in wild-type mice when fed a high-fat diet after 8 weeks
• however, interscapular brown adipose tissue is normal in mice fed normal chow
• 2-fold greater uncoupled oxygen consumption in vitro compared with wild-type cells

liver/biliary system
• in female mice
• mice fed a high-fat diet fail to exhibit an increase in liver triglyceride levels compared with wild-type mice

neoplasm
• at necropsy (in mice between 845 and 850 days age) no malignancies are detected in 6 mice compared to 4 out of 6 wild-type mice

behavior/neurological
N
• whether fed normal chow or a high-fat diet, mice exhibit normal food intake and physical activity
