| Outline of Final Research Achievements |
To study the pathophysiology of fatty liver due to undernutrition, new LC-MS/MS methods were developed for metabolomics analysis of patients’ serum. By use of the methods, we analyzed serum from Crohn’s disease and citrin deficiency that are often accompanied by fatty liver due to undernutrition. Activation of LXR and deactivation of FXR were detected in Crohn’s disease while stimulation of fatty acid biosynthesis by oversupply of citrate was observed in citrin deficiency. Thus, serum metabolomics analysis is a useful method to explore the mechanism of fatty liver due to unknown origin.
