Outline of Final Research Achievements |
In this study, we utilized state-of-the-art splicing analysis techniques across various cancers to identify multi-layered abnormalities in the genome, gene expression, and splicing through Omics analysis. Additionally, we developed hireCLIP-seq, which allows high-precision and high-reproducibility profiling of RNA-binding proteins (RBPs), and elucidated various splicing regulatory mechanisms of SR proteins. Furthermore, through screening focused on RBPs, we identified an essential RBP for the survival of Ewing sarcoma and developed a novel treatment for Ewing sarcoma by creating an ASO that inhibits the binding of this RBP to driver genes.

Academic Significance and Societal Importance of the Research Achievements |
本研究では、がん細胞から得られた様々な種類のデータの解析を組み合わせることによって、新たな治療標的や、臨床で薬剤の効果を予測するようなバイオマーカーを同定することに成功した。特に、コロナワクチンで有名になった核酸医薬をがん治療に用いるべく、複数のがん種に対して核酸医薬を開発した。今後は核酸医薬の腫瘍細胞への安定したデリバリーを可能にするシステムを最適化することにより、臨床応用への可能性を模索する。これらの研究が成功すれば、がん全体の3%以上の患者に適応可能な複数の治療法が得られることとなる。
