Outline of Final Research Achievements |
By conducting a plasma metabolomic analysis of a rat model of fatigue, the fatigued rats showed distinctive changes in metabolites related to branched-chain amino acid metabolism, urea cycle, and proline metabolism. Further, the levels of ATP were significantly decreased in the liver and skeletal muscle of the fatigued rats, indicative of a deterioration in energy metabolism in these organs. We biochemically examined an influence of ornithine, one of metabolites in urea cycle, forward the urea cycle and energy metabolism. The ornithine administration has limited effectiveness on energy metabolism and urea cycle while a flow of ornithine to other pathways was observed.
