homeostasis/metabolism
• males and females have more serum lipid than wild-type mice
|
• serum free fatty acid levels are increased by 90% relative to wild-type mice
|
• fasting triglyceride levels are increased relative to in wild-type mice
|
• in a euglycemic clamp assay, mice require a reduced rate of glucose infusion compared to wild-type mice to maintain euglycemia
|
• in mice fed ad libitum, serum glucose levels are increased
• fasting glucose levels during insulin and glucose tolerance tests is increased by 20% to 25%
• when dietary fat content is increased from 5% to 10% for 2 months, mice exhibit higher glucose levels than in wild-type mice at all time points and during fasting glucose tolerance testing
|
• in mice fed ad libitum, serum insulin levels are increased
|
• in mice fed ad libitum, glucose tolerance impairment is comparable to or more severe than in homozygotes
|
• in mice fed ad libitum, insulin tolerance is impairment is comparable to or more severe than in homozygotes
• in a euglycemic clamp assay, whole-body insulin resistance is accounted for by decreases in insulin-stimulated whole-body glucose uptake and muscle glucose uptake of 25% and 30%, respectively
|
cardiovascular system
muscle
• insulin-stimulated uptake of glucose and [3H]2-deoxyglucose in vastus laterallis, soleus and extensor digitorum longus, and heart muscles is reduced by 50% to 60% compared to in wild-type mice
|
liver/biliary system
• even on a low-fat diet, hepatostetosis occurs and is more pronounced in heterogyzotes than in homozygotes
|
adipose tissue
• insulin-stimulated glucose transport is impaired
|
growth/size/body
• body weight is increased relative to wild-type mice and homozygous mice
|
• mice develop an obesity/diabetes syndrome associated with increased food intake
|
behavior/neurological
• mice consume 20% more regular chow than wild-type mice
|
immune system
• mice develop an obesity/diabetes syndrome associated with increased food intake
|
endocrine/exocrine glands
cellular
• insulin-stimulated glucose transport is impaired
|
• insulin-stimulated uptake of glucose and [3H]2-deoxyglucose in vastus laterallis, soleus and extensor digitorum longus, and heart muscles is reduced by 50% to 60% compared to in wild-type mice
