Outline of Final Research Achievements |
The period of the circadian rhythm is kept relatively constant over a wide range of temperatures, which means “temperature compensation”. So far, it is impossible to change body temperature of warm-blooded mammals. NRDc deficient mice (KO) that we generated have a feature as so-called “cold-blooded mice”. To evaluate the correlation between environmental temperature and body temperature, we housed KO mice at high temperature (38℃) and low temperature (10℃). Body temperature of KO mice became 38℃ and 35℃, respectively. However, it is difficult to keep these body temperatures for a long period.
