Outline of Final Research Achievements |
We evaluated the circadian phenotypes of patients with delayed sleep-wake phase disorder (DSWPD) and non-24-hour sleep-wake rhythm disorder (N24SWD), two different circadian rhythm sleep-wake disorders (CRSWDs) by measuring Bmal1-luciferase (Bmal1-luc) rhythms in fibroblast cells derived from individual patients (in vitro rhythms). The period length of the Bmal1-luc rhythm (in vitro period) varied among individuals.The N24SWD group showed a significantly longer in vitro period than did the control or DSWPD group. Furthermore, in vitro period was associated with response to chronotherapy in the N24SWD group. Longer in vitro periods were observed in the non-responders compared to the responders in the N24SWD group. In vitro rhythm assays could be useful for predicting circadian phenotypes and clinical prognosis in patients with CRSWDs.
