Outline of Final Research Achievements

In this study, we newly identified a MIF signaling cascade, MIF-CHD7-TPT1-ZFHX4 in mouse NSPCs in vitro. In mouse embryonic brain, Zfhx4 was expressed in the ventricular zone of the cortex. Moreover, we generated a Zfhx4 knockout mouse using a Cas9 system. In Zfxh4 knockout fetal mouse, the number of Tbr2-positive cells in the cortex was decreased compared to wild type. In addition, ZFHX4 was highly expressed in glioma and regulated the cell proliferation of glioma cancer stem cells in vitro. Taken together, ZFHX4 may be a new candidate for a molecular targeting drug to treat glioma.

Academic Significance and Societal Importance of the Research Achievements

MIFがマウス神経幹細胞,ヒトES細胞由来神経幹細胞, グリオーマ幹細胞において、細胞増殖能を担うという発見を、その分子論的基盤を明らかにすることにより、より精緻なものとすることができた。とくに、MIF下流で新たに機能する因子として、ZFHX4を同定した。マウス胎児脳では、ヒト胎児脳同様に脳室周囲でのZFHX4の発現を見出した。ZFHX4が中間前駆細胞の発現制御を担うことが明らかとなったが、成体脳では海馬で発現することから、当該因子の高次脳機能における機能解明の重要性が明らかとなった。さらに、ZFHX4がグリオーマ幹細胞の細胞増殖に関わることから、治療薬開発に寄与する可能性が示された。
