liver/biliary system
• mice fasted for 24 hours show accumulation of diacylglyceride, triglyceride, and phosphocholine in the liver compared fasted wild-type mice
• however, mice fasted for 24 hours show normal liver index, body weight loss, serum ALT and AST levels, serum total cholesterol and triglyceride levels, and serum non-esterified fatty acid levels
• treatment with a PPARalpha agonist, WY14643, to induce pharmacological stress results in the same level of hepatomegaly and decreased triglyceride and cholesterol levels in the liver as in wild-type treated mice
|
• mice fasted for 24 hours show elevated hepatic levels of cholesterol
|
• mice fasted for 24 hours show elevated hepatic levels of non-esterified fatty acids
|
• mice fasted for 24 hours show elevated hepatic triglyceride levels
|
• mice fasted for 24 hours show more widespread liver lipid droplet accumulation than fasting wild-type mice
|
homeostasis/metabolism
• mice fasted for 24 hours show elevated hepatic levels of cholesterol
|
• mice fasted for 24 hours show elevated hepatic levels of non-esterified fatty acids
|
• mice fasted for 24 hours show elevated hepatic triglyceride levels
