Outline of Final Research Achievements

Among 15 polyphenols, which stimulate glucose uptake in muscle cells, glabridin, 4-hydroxyderricin, and xanthoangelol suppressed the dexamethasone-induced protein degradation. On the other hand, all compounds tested did not promote the protein synthesis. We focused on glabridin and investigated its underlying molecular mechanism. Glabridin inhibited protein degradation and muscle atrophy through suppressing p38/FOXO3a and glucocorticoid receptor pathways. Glabridin tended to suppress oxygen consumption during exercise. Moreover, we elucidated molecular mechanisms of GLUT4 translocation in muscle cells by EGCG andtheaflavin, which also stimulate glucose uptake in muscle cells. However, EGCG did not affect exercise capacity. On the other hand, a GLUT inhibitor phlorizin suppressed oxygen consumption and lipid metabolism, in addition to delaying hydrocarbon utilization.
