Outline of Final Research Achievements |
Multiple myeloma is a malignancy of terminally differentiated B cells (plasma cells). In this study, we showed that one of the histone demethylases KDM5A mediates myeloma cell growth. Mechanistically, KDM5A coexists with MYC across the genome, and KDM5A and MYC coordinately activate MYC target gene transcription. We also demonstrated that novel KDM5 inhibitor is effective in vitro and in vivo myeloma xenograft model.

Academic Significance and Societal Importance of the Research Achievements |
KDM5Aは転写活性化に関わるヒストン修飾であるH3K4me3の脱メチル化酵素であるため、転写抑制因子として働くと考えられているが、本研究はKDM5AがMYCの共役因子として転写を活性化するという新たな機能を提示した。また、新規KDM5阻害がin vivoで有効であるとともに、十分な忍容性があることを示し、KDM5阻害剤を用いた骨髄腫新規治療法の可能性を提示した。
