| Outline of Final Research Achievements |
In this study, we studied the mechanism of anti-melanogenic and anti-tumorgrowth effects of EPA and DHA. We revealed that 1) EPA decreased Tyrosinase and Tyrosinase related protein 1 that located on membrane, 2) DHA delayed the cell cycle of melanoma that involved G2/M phase cell increase. To reveal these mechanism, we examined the protein expression and localization of small GDP-binding proteins. However, we could not observe any difference whether EPA or DHA treated. Therefore, we analyzed cytoskeleton protein, and observed fiber actin was decreased by EPA treated. Our results suggested that a new mechanism of anti-melanogenic and anti-tumorgrowth effects of EPA and DHA via decreasing of F-actin was exist.
