adipose tissue
• adipocytes are smaller in size while the weight of adipose tissue remains the same

homeostasis/metabolism
• mice fed a high-fat diet for three weeks have almost half the serum levels of leptin compared to wild-type mice
• free fatty acid levels in mice fed a high fat diet for 4 weeks are significantly lower than controls fed the same diet
• triglyceride levels in mice fed a high fat diet for 4 weeks are significantly lower than controls fed the same diet
• mice have higher tolerance to glucose challenge after being fed a high-fat diet for 8 weeks compared to wild-type mice fed the same diet
• mice have a third higher glucose uptake on a per gram bodyweight basis than in controls
• mice fed a high fat diet for 11 weeks have higher drops in blood sugar upon insulin challenge compared to wild-type mice fed the same diet
• mice have a lower score than controls on the homeostasis model assessment measure of insulin sensitivity
• mice fed a high-fat diet for 19 weeks have higher serum levels of adiponectin and increased expression of the adiponectin gene in their white adipose tissue

• the characteristic resistance of Dok1tm1Yyam homozygotes to a high fat diet in terms of weight gain, adipose tissue growth, and rises in serum levels of leptin and insulin are normalized when mice are on a Ppargtm1Laz homozygote background
• size of adipocytes is smaller compared to wild-type controls when a high-fat diet
