phenotype observed in males
N normal phenotype
growth/size/body
N
• when fed a Western diet for 18 weeks, mice show no differences in total increase in body weight and composition relative to controls
• at 1 year, but not at 3 months, of age, percentage of lean mass is significantly higher than in control mice
• at 1 year, but not at 3 months, of age, body weight is significantly lower than that in control mice

adipose tissue
N
• at 1 year of age, inguinal and visceral adipose tissues show no differences in WAT droplet size relative to control mice; lipid accumulation phenotype is unchanged in Western diet-fed mice
• at 1 year of age, intracapsular brown adipose tissue (iBAT) shows significantly less fat accumulation (pixels of fat droplets/area) than in control mice
• at 1 year, but not at 3 months, of age, percentage of fat mass is significantly lower than in control mice

homeostasis/metabolism
N
• at 3 months of age, mice exhibit normal glucose tolerance relative to control mice
• when fed a Western diet for 18 weeks, mice show normal glucose tolerance and no differences in calorimetry relative to controls
• at 1 year of age, mice exhibit increased heat production over time and a significant increase in heat production per body weight

liver/biliary system
N
• mice show no fat accumulation in the liver at 1 year of age

behavior/neurological
• at 1 year of age, total food intake is not significantly altered, either under basal or refeed-challenged conditions; refeed responses are also unchanged in Western diet-fed mice
• at 3 months of age, mice do not exhibit altered anxiety-related behavioral phenotypes
• at 3 months and at 1 year of age, mice exhibit increased dark-phase locomotion, as indicated by the light beam breaks count
