Outline of Final Research Achievements

In this study, we found flavonoid, morin in brown algae. Next, we examined the effect of dietary marine flavonoid containing morin, on the wasting of muscle. The wet weight and myofiber size of skeletal muscle in tumor-bearing mice, which is known to muscle atrophy model, significantly decreased, compared with that of vehicle-injected control mice. In contrast, the wet weight and myofiber size of skeletal muscle in tumor-bearing mice fed the marine flavonoid diet were nearly the same as those in vehicle-injected control mice. Moreover, treatment of marine flavonoid in C2C12 myotube inhibited myotube atrophy induced by tumor. These results suggest that dietary marine flavonoid suppresses muscle wasting in tumor-bearing mice. Thus, marine flavonoid may be efficacious in a therapeutic approach against the wasting of muscle.
