Outline of Final Research Achievements

There are two similarities between lifestyle-related diseases and cancer. The first point is that they are in a chronic inflammatory state, and the second point is that abnormal activation of mTORC1 is observed. Based on these similarities, we hypothesized that the transcription factor FOXK1, which is activated downstream of mTORC1, promotes both of lifestyle-related diseases and cancer. We identified that FOXK1 deficient mice were improved fatty liver-related inflammation, fibrosis, and tumorigenesis.

Academic Significance and Societal Importance of the Research Achievements

生活習慣病、特に非アルコール性脂肪性肝炎の患者数は増加傾向にあり、アルコール性・ウイルス性肝炎が減少傾向にあることと対照的である。治療法の確立は急務であるが、現在は減量を基本とした治療法以外は存在しない。本研究では、非アルコール性脂肪性肝炎の新たな治療ターゲットとしてFOXK1を見出した。FOXK1を標的とした薬剤の開発は脂肪肝と関連する炎症、線維症、および腫瘍形成を抑制する可能性がある。
