Outline of Final Research Achievements

In adult humans, beige adipocytes, which are induced in adipose tissue through a phenomenon called browning, are a potential therapeutic target for preventing obesity and related metabolic diseases by consuming circulating blood glucose and fatty acids. In this study, we used ciBAs, a model of human brown adipocytes converted from primary dermal fibroblasts, and verified that ciBAs are functional brown adipocytes similar to those in vivo by analyzing the conversion mechanism. We newly evaluated small molecules and dietary compounds using ciBAs, and discovered multiple new factors that have the potential to promote browning in the body. In this study, their effects and mechanisms of action on browning were analyzed in detail.

Academic Significance and Societal Importance of the Research Achievements

本研究から、ヒト皮膚線維芽細胞から誘導される褐色脂肪細胞ciBAが、生体内に類似の前駆細胞から誘導されることが示唆され、誘導メカニズムの一端が明らかとなったことで、より信頼性の高い細胞モデルとなった。そして、このciBAを用いて代表的な食品成分や種々の低分子化合物を新たに評価したことで、褐色化を促進する可能性のある新規な化合物を複数発見し、その効果と作用機序について学術論文として報告した。これらの研究成果を通して、普段の食事やサプリメントから、体内の褐色脂肪細胞を増加させることによる、長期的かつ健康的な肥満および生活習慣病の予防へつながることが期待される。
