homeostasis/metabolism

abnormal intestinal lipid absorption ( J:319817 )

• mice exhibit reduced triglyceride concentration after olive oil intragastric administration indicating intestinal fat malabsorption

• an increase in triglyceride and total cholesterol is seen in the gut following fat load

abnormal circulating non-HDL cholesterol level ( J:319817 )

• mice show an increase in non-HDL cholesterol

decreased circulating cholesterol level ( J:319817 )

decreased circulating HDL cholesterol level ( J:319817 )

decreased circulating triglyceride level ( J:319817 )

abnormal lipid metabolism ( J:319817 )

• protein and gene expression analysis shows altered intestinal, but not liver, lipid metabolism, with a plausible enhancement of fatty acid beta-oxidation in the intestine and decline in lipogenesis process

decreased lipogenesis ( J:319817 )

• chylomicron lipid content shows lower triglyceride and total cholesterol content, indicating depressed chylomicron output

digestive/alimentary system

abnormal intestinal lipid absorption ( J:319817 )

• mice exhibit reduced triglyceride concentration after olive oil intragastric administration indicating intestinal fat malabsorption

• an increase in triglyceride and total cholesterol is seen in the gut following fat load
