Outline of Final Research Achievements

Although isocitrate dehydrogenase (IDH)-wild-type diffuse astrocytic glioma (DAG) shows a more aggressive phenotype than IDH-mutant type, lack of knowledge regarding relevant molecular drivers for this type of tumor has hindered the development of therapeutic agents. Here, we generated a glioma mouse model, which concurrently lacks p53 and NF1 and develops tumors highly comparable with human IDH-wild-type DAG without characteristic molecular features of glioblastoma. During tumor formation, Ezh2 was upregulated and histone H3K27me3 was increased on target genes. Inhibition of Ezh2 activity effectively repressed tumor growth in vivo. Our study clarifies a pathogenic molecular pathway of IDH-wild-type DAG that depends on Ezh2 activity, and that targeting Ezh2 might be a promising treatment option for this type of glioma.

Academic Significance and Societal Importance of the Research Achievements

悪性脳腫瘍のゲノム解析により細分類されている。従来の抗がん剤治療が有効なものもあるが、未だ予後不良なものがある。予後不良な脳腫瘍はゲノム異常が十分解明されていないため、有効な治療法が見出せないでいることが原因のひとつである。我々は、抗がん剤の無効な脳腫瘍のゲノム異常から惹起されるエピゲノム異常を明らかにした。その中でヒストン修飾をするEZH2の異常を発見し、EZH2に対する阻害剤が有効であることを解明した。
