| Outline of Final Research Achievements |
Many physiological functions have diurnal variation that follows an approximately 24-hour cycle and is regulated by an endogenous circadian clock. Recently, individual differences in circadian period length have been shown to be associated with circadian disorders. For example, familial advanced sleep phase syndrome (FASPS) is an autosomal dominant disease characterized by a natural tendency to go to sleep and wake up at times considered earlier than normal. In this study, we established a novel circadian disorder model using pluripotent stem cells, first in vitro that recapitulated the period shortening seen in FASPS. Moreover, we found 2 chemical compoundss regulating circadian rhythm from Japanese herbal medicine. These systems would be applicable to real-time bioluminescence analysis using patient-derived iPS cells and may also contribute to Tailor-made screening of circadian drugs.
