Outline Activities

Animals exhibit biological rhythms, e.g., daily rhythms and seasonal rhythms, in behaviors and physiological functions. Our lab focuses on several topics in the biological rhythms using rodents and domestic animals.
1. Adaptive stress response to environmental changes is important to maintain homeostasis. We are trying to clarify the molecular and physiological mechanisms underlying eustress with cyclic environment.
2. Seasonal changes in photoperiod influence animal behaviors and physiological functions. In humans, photoperiod is related to seasonal affective disorder (SAD, winter depression). Birth seasons also affect life-time risks of psychiatric/neurological diseases. We are elucidating epigenetic mechanisms underlying the programming effect of early-life photoperiod.
3. Disruption of the circadian clock by irregular light-dark cycles is a serious problem in the world. The circadian disruption increases risk of many diseases such as cancer. We are trying to identify functional nutrients that can ameliorate the circadian disruption.

Message

We aim to clarify mechanisms underlying biological rhythms and stress responses in animals to contribute to health science and animal production.
