Outline of Research at the Start

生後12ヶ月以内の乳児期に発症した白血病(乳児白血病)は、治療が難しく予後不良である。特にMLL遺伝子再構成陽性群、さらにその中でも転写因子IRX1が高発現する群は極めて予後不良であり、病態の解明と新しい治療法の開発が必要とされている。本研究では、申請者が開発した乳児白血病モデルを用いて、乳児白血病の起源となる細胞を同定する。さらに、同定した乳児白血病起源細胞の多能性を検証する。

Outline of Final Research Achievements

B-cell acute lymphoblastic leukemia with MLL-AF4 translocation is the most common childhood cancer. There are two types, HOXA9 type with high expression of HOXA9 and IRX1 type with high expression of IRX1; HOXA9 type is common in older children and adults, while IRX1 type is found only in infants. In this study, we transduced MLL-AF4 into human cord blood CD34+ cells and transplanted them into immunodeficient NSG mice to generate MLL-AF4 leukemia models with high expression of IRX1 or HOXA9. We also performed single-cell RNA-seq and found that the expression of stem cell-related genes was upregulated in the IRX1 type. These results provide a basis for the development of therapeutic strategies for MLL-AF4 translocated infant leukemia.

Academic Significance and Societal Importance of the Research Achievements

生後1年未満の乳児に発症する白血病を乳児白血病と言います。乳児白血病の多くでMLL遺伝子の異常が認められ、特に、MLL-AF4転座型乳児白血病は、頻度が高くかつ予後も悪いことから臨床上の大きな問題になっています。MLL-AF4転座型白血病は、HOXA9の発現が高いHOXA9型と、IRX1の発現が高いIRX1型の2タイプに分けられます。本研究では、ヒト臍帯血由来の造血幹細胞にMLL-AF4を導入してHOXA9型、IRX1型の2種類の乳児白血病モデルを作製し、さらに単一細胞RNAシークエンシングを行って両者の病態を明らかにしました。これは、乳児白血病に対する治療法開発の基盤となる成果です。
