cellular
• high fat diet fed mice show distended and dilated endoplasmic reticulum
|
• livers of high fat diet fed mice exhibit continuous hepatocyte death and compensatory proliferation
• hepatocytes treated with PA show more extensive lipotoxic cell death than wild-type hepatocytes
• PA treated hepatocytes treated with the chemical chaperons 4-phenylbutyrate (4-PBA) and tauro-ursodeoxycholic acid (TUDCA), which reduce ER stress, show a more pronounced attenuation of cell death than wild-type hepatocytes
|
homeostasis/metabolism
• mice fed a high fat diet starting at 6 weeks of age maintain high serum alanine aminotransferase (ALT) levels throughout the observation period
• high fat diet fed mice treated with TUDCA at 16 weeks of age exhibit reduced serum ALT levels
|
• mice fed a high fat diet exhibit elevated liver cholesterol levels
• high fat diet fed mice treated with TUDCA at 16 weeks of age exhibit reduced hepatic cholesterol levels
|
• mice fed a standard chow diet show an increase in C16:0 palmitic acid and longer chain fatty acid in the liver compared to wild-type mice, which is further enhanced by high fat diet feeding
|
• mice fed a high fat diet exhibit elevated liver triglycerides
• high fat diet fed mice treated with TUDCA at 16 weeks of age exhibit hepatic triglyceride levels
|
immune system
• high fat diet fed mice show increased levels of IL-1beta in the liver at 24 weeks of age
|
• high fat diet fed mice show increased levels of TNF in the liver at 24 weeks of age
• TUDCA treatment of high fat diet fed mice inhibits the TNF increase seen in the liver
|
• mice fed a high fat diet exhibit extensive immune infiltration into the liver and numerous ballooning hepatocytes, indicating non-alcoholic steatohepatitis
• mice fed a high fat diet show an increase in the number of F4/80-positive macrophages in the liver
• TUDCA treatment of high fat diet fed mice inhibits the increase in macrophage infiltration in the liver
|
liver/biliary system
• livers of high fat diet fed mice exhibit continuous hepatocyte death and compensatory proliferation
• hepatocytes treated with PA show more extensive lipotoxic cell death than wild-type hepatocytes
• PA treated hepatocytes treated with the chemical chaperons 4-phenylbutyrate (4-PBA) and tauro-ursodeoxycholic acid (TUDCA), which reduce ER stress, show a more pronounced attenuation of cell death than wild-type hepatocytes
|
• 30% of normal chow fed mice display a few tiny nodules in the liver at 40 weeks of age, indicating hyperplasia
|
• mice fed a high fat diet exhibit elevated liver cholesterol levels
• high fat diet fed mice treated with TUDCA at 16 weeks of age exhibit reduced hepatic cholesterol levels
|
• mice fed a standard chow diet show an increase in C16:0 palmitic acid and longer chain fatty acid in the liver compared to wild-type mice, which is further enhanced by high fat diet feeding

• mice fed a high fat diet show an increase in the number of F4/80-positive macrophages in the liver
• TUDCA treatment of high fat diet fed mice inhibits the increase in macrophage infiltration in the liver
|
• mice fed normal chow exhibit hepatocyte damage at 5 weeks of age but this disappears at 24 weeks, except for mild inflammation and spotty necrosis
• mice fed a high fat diet exhibit numerous ballooning hepatocytes
• high fat diet fed mice treated with TUDCA at 16 weeks of age exhibit attenuation of hepatocyte ballooning
|
• livers of high fat diet fed mice show increased apoptotic and necrotic cell death
|
• mice fed a standard chow diet exhibit mild spontaneous lipid accumulation in the liver at 5 weeks of age that is diminished by 16 weeks of age
• mice fed a high fat diet show extensive lipid accumulation in the liver
• high fat diet fed mice treated with TUDCA at 16 weeks of age exhibit attenuation of hepatosteatosis
|
• high fat diet fed mice develop small tumors on the liver surface by 32 weeks of age and large tumors at 40 weeks
|
• 30% of tumors larger than 2 mm are hepatocellular carcinomas, similar to human steatohepatitic hepatocellular carcinomas, although some show a classical thick trabecular pattern
• hepatocellular carcinoma progenitor cell-transplanted mutants develop multiple hepatocellular carcinoma nodules after 5 months
|
• 70% of tumors are either typical or steatohepatic adenomas
