Outline of Research at the Start

神経芽腫は小児固形腫瘍であり、がん遺伝子MYCNが増幅し過剰発現する。MYCN増幅を伴う神経芽腫は高頻度で遠隔転移を起こし、その長期生存率は50%程度である。MYCNを交感神経節に特異的に過剰発現するMYCN Tgマウスは神経芽腫を自然発症するが、遠隔転移は稀でありヒトの病態を反映しない。研究代表者らはMYCN/NCYM Tgマウスを作製し、転移能を示す神経芽腫を発症することを示した。この転移能は分裂期の細胞死抑制に起因するが、その分子機構が明らかではない。本研究ではNCYMによる分裂期制御機構を明らかにすることで神経芽腫転移を抑制する薬剤の標的分子を同定する。

Outline of Final Research Achievements

NCYM, an antisense gene of MYCN, contributes to tumor progression by promoting distant metastasis in neuroblastoma. The contribution of NCYM to tumor progression involves inhibition of cell death during mitosis, but the detailed molecular mechanism has not been elucidated. In this study, we found that the 52nd asparagine residue is important for the production of Myc-nick, which is important for mitotic regulation by NCYM. Transcriptome analysis showed that NCYM globally promote the translational efficiency of mitosis-related genes, and holographic microscopy with the treatment of NCYM inhibitors revealed that NCYM regulates an unknown type of mitotic cell death.

Academic Significance and Societal Importance of the Research Achievements

NCYMの分裂期制御機構の一端が明らかにされたことで、NCYMがなぜ神経芽腫のがん進展を促進できるのかについての理解が深まった。またNCYM阻害剤が同定されたことで、この阻害剤が神経芽腫における新規薬剤候補となる可能性が浮上した。今後、本研究で同定された未知の細胞死様式が解明されることで、これまでのがん治療薬とは全く作用機序が異なる治療法が開発できる可能性がある。
