homeostasis/metabolism
• following cold exposure or fasting, mice exhibit reduced body temperature compared with wild-type mice
|
• during the dark period
|
• during the dark period
|
• in cold-exposed mice
|
• to a great extend in cold-exposed mice than in similarly treated wild-type mice
|
• cold-exposed mice do not exhibit an increase in liver fatty acid content unlike in similarly treated wild-type mice
|
• in the heart and brown adipose tissue after cold exposure
|
• in the liver
|
• to a great extend in cold-exposed mice than in similarly treated wild-type mice
|
• cold-treated mice fail to exhibit an increase in heart, muscle, or liver triglyceride levels unlike similarly treated wild-type mice
|
• in the brown adipose tissue of cold-treated mice
|
• in the heart and brown adipose tissue
|
• to a great extend in cold-exposed mice than in similarly treated wild-type mice
|
adipose tissue
• brown adipose tissue exhibit a 2-fold increase in mitochondrial DNA content compared to in wild-type mice
|
• after 4 hours of cold exposure
|
• in response to fatty acid administration, brown adipose tissue at room temperature or 4 degree Celsius oxygen consumption is lower than in wild-type tissue
• brown adipose tissue and primary brown adipocytes exhibit impaired fatty acid oxidation compared with wild-type mice
|
liver/biliary system
• to a great extend in cold-exposed mice than in similarly treated wild-type mice
