| Outline of Final Research Achievements |
Brown adipocytes dissipate caloric energy as heat, thereby being a potential therapeutic target in the battle against obesity and metabolic diseases. To clarify the mechanism of brown adipocyte differentiation, we investigated a number of candidate genes expected to be involved in the process and found a novel gene, cellular repressor of E1A-stimulated genes 1 (CREG1), coding a secreted glycoprotein. In adipocyte culture, Creg1 gene expression increased with the differentiation of brown adipocytes, which was also stimulated by addition of the purified protein. Administration of CREG1 protein stimulated brown adipocyte differentiation and improved fatty liver in mice. Our results suggest that CREG1 contributes to the regulation of whole body energy homeostasis as an endocrine molecule.
