| Outline of Final Research Achievements |
Brown adipocytes play a specific role for heat production by dissipating caloric energy, contributing to body temperature and weight regulation; however, the mechanism of brown adipogenesis remains to be fully understood. We recently found that cellular repressor of E1A-stimulated genes 1 (Creg1) is a novel regulator of brown adipogenesis. In the present study, we investigated the action mechanism of Creg1 and its physiological role. As the results, we found that Creg1 binds to IGF2R and stimulated Ucp1 transcription in vitro. In addition, we created aP2-Creg1-Tg mice, in which brown/beige adipogenesis was prominent in adipose tissues compared to wild-type mice. These results suggested that Creg1 acts as a transcriptional regulator for brown adipogenesis through autocrine/paracrine mechanism.
