| Outline of Final Research Achievements |
Although BMP-3b is highly expressed in adipose tissues, its functions were yet to be clarified. We showed that BMP-3b inhibited adipogenesis in cultured adipocytes. We generated adipose tissue specific BMP-3b transgenic mice (Tg) to examine BMP-3b functions in vivo. Tg mice exibited anti-obesity effect and increased energy expenditure. We found that PPARγ and its target gene fatty acid translocase (FAT/CD36) were suppressed in Tg mice, indicating that suppression of translocation of fatty acid into adipocytes leaded to prevention of obesity. We also showed that enhanced BAT function and locomoter activity, which might cause increased energy expenditure.
