| Outline of Final Research Achievements |
The circadian clock has an about 24 hour periods. Chronic desynchronization of circadian clock from the environmental rhythms is possibly thought to cause many diseases. The central circadian clock is located in the suprachiasmatic nucleus (SCN) of the hypothalamus, and controls many circadian rhythms. The circadian clock also reside throughout the body, and these peripheral clocks are entrained by the signals from the SCN. Desynchronization between SCN and peripheral clocks has been found to cause health problems. In this study, we aimed to search for odorants which effectively control the phase of the peripheral clocks. To address this, we induced jet lag in mice, and constructed apparatus to automatically give odor stimuli to them. We gave two odorants to mice, but could not observe any effects on the clock in liver.
