Outline of Final Research Achievements

In Drosophila, it was elucidated that the transcription and translation feedback loop of the clock gene causes a circadian rhythm with a period of about 24 hours, and it won the 2017 Nobel Prize in Medicine and Physiology. We cloned mammalian Per gene in 1997, and clarified that the circadian oscillation was not generated simply clock genes by themselves, but needs intercellular neurotransmission among clock oscillating cells. In this research project, we identified GPR176-cAMP system as a key system to generate the rhythm, mathematical model of jet lag, alternative splicing of Ck1d gene for determining period length, mammalian calcitonin receptor in temperature regulation during nap, and role of Per for the formation of polyploidization.
