N normal phenotype
adipose tissue
• mice accumulate a greater amount of retroperitoneal fat

cellular
• liver mitochondria shows clustered and occasionally fused organelles at 50 weeks
• succinate-linked state 3 respiration is decreased by 44% and pyruvate-linked respiration is decreased by 35%
• the activity of the linked complex II-III is reduced by 60% in liver mitochondria
• content of total coenzyme Q is lower in livers
• hepatocytes produce a 1.5-fold higher level of reactive oxygen species

endocrine/exocrine glands
• insulin secretion is lower after a 16 hour fast followed by a glucose load

growth/size/body
• mice weigh 26% more than wild-type mice at 20 weeks of age
• liver weights are slightly higher at 10 and 20 weeks of age

homeostasis/metabolism
• insulin secretion is lower after a 16 hour fast followed by a glucose load
• 2 hours after the insulin tolerance test, glucagon levels are lower
• 2 hours after the insulin tolerance test, corticosterone levels are higher
• corticosterone plasma levels are higher in fed mice and increase further after fasting
• non-fasting interprandial insulin concentrations are increased 2-fold at 20 and 30 weeks of age
• plasma leptin is higher at 20 weeks of age
• total cholesterol is slightly higher at 10 and 20 weeks of age
• plasma triglyceride concentrations are lower only at 30 weeks of age
• albumin concentrations are increased slightly at 30 weeks of age
• mutants show a significant lowering of body temperature in response to fasting, suggesting a reduction in basal metabolic energy
• noradrenaline levels are lower 2 hours after the insulin tolerance test
• glucose tolerance test showed higher glucose levels
• however, random interprandial blood glucose and fasting blood glucose are normal
• in the insulin tolerance test, mutants remain hypoglycemic at 90 minutes after similar initial fall in blood glucose as in wild-type mice instead of becoming euglycemic
• mice are more vulnerable to repeated challenges of insulin-inducing hypoglycemia
• plasma adiponectin levels are slightly higher at 10, 20 and 30 weeks of age
• increase in liver triglycerides at 30 weeks
• glutamate dehydrogenase activity is decreased by 60% in livers

liver/biliary system
• liver mitochondria appears clustered and occasionally fused at 50 weeks
• liver mitochondria shows clustered and occasionally fused organelles at 50 weeks
• liver weights are slightly higher at 10 and 20 weeks of age
• increase in liver triglycerides at 30 weeks
• large lipid droplets occur frequently in livers at 20 and 30 weeks of age
• hepatocytes produce a 1.5-fold higher level of reactive oxygen species
