| Outline of Final Research Achievements |
Hair graying is an ordinary disorder for hair pigmentation and a symbol for aging. At present, mechanism of hair graying remains largely unknown, whereas reports for genetically modified mice with changing levels of hair pigmentation are increasing in international scientific journals, according to the recent progression of molecular biology. However, there is very limited report showing model mouse lines for hair graying with aging. We developed original mouse lines for hair graying with aging. In this study, we clarify pathogenesis and molecular mechanism of hair graying in the mice. We also provide the evidence that the mice could be appropriate model mice for hair graying with aging. Moreover, we challenge to develop molecular target therapy for anti-hair graying.
