Outline of Final Research Achievements

Since miRNA overturns the classical concept that cell differentiation is determined by transcription factors, miR-195 was introduced into EBF1-deficient hematopoietic progenitor cells, which are essential for B cell differentiation, and we tried to induce differentiation. As a result, the B cell lineage cell surface marker CD19 could be reproducibly induced. In EBF1-deficient hematopoietic cells overexpressing miR-195, Atac-seq analysis revealed that the EBF1-binding genomic region was open. In miR-195-deficient mice, abnormal lymphocyte differentiation was observed, and the hypothesis was generally correct.

Academic Significance and Societal Importance of the Research Achievements

転写因子中心の細胞運命決定における従来の古典的概念を覆す、単一miRNAでの転写因子の補完が可能との研究成果の学術的意義は極めて高いと考える。事実、海外学会で高い評価が得られている。また、分化誘導療法はレチノイン酸を用いて、既に白血病治療で行われていることからも。本研究結果も同様の治療コンセプトで分化誘導療法に応用されるポテンシャルを有する。よって、既に癌治療において行われているmiRNAを用いた治療にもつながり、社会的意義も高いと考える。
