adipose tissue
adipose tissue phenotype ( J:156376 )
N
• unlike in white adipose tissue, no defects are detected in the brown adipose tissue
decreased subcutaneous adipose tissue amount ( J:156376 )
• decrease in the weight of subcutaneous WAT relative to total body weight compared to wild-type controls
decreased white adipose tissue amount ( J:156376 )
• decrease in WAT weight compared to wild-type controls
• decrease in the weight of visceral WAT relative to total body weight compared to wild-type controls

homeostasis/metabolism
improved glucose tolerance ( J:156376 )
• display less high fat diet induced hyperglycemia in an intraperitoneal glucose tolerance test
increased insulin sensitivity ( J:156376 )
• hypoglycemic response to insulin is increased compared to wild-type controls

cellular
abnormal cell differentiation ( J:156376 )
