Outline of Research at the Start

極めて予後不良な脳幹腫瘍DIPGの原因遺伝子としてH3F3A遺伝子のK27M変異が分かってきており、精力的に研究が行われ、さまざまな遺伝子異常、エピゲノム異常が報告されている。我々が樹立したK27M異常を有する幹細胞株では、既存の治療法では全く歯が立たず治療抵抗性であった。この腫瘍に対して、近年ドーパミンD2受容体(DRD2)拮抗薬であるONC201が注目を集めており我々も解析を行っている。本研究ではこのような幹細胞株に対して、その耐性のメカニズムを解析するとともに、H3K27M変異に関連する作用機序の異なるいくつかの分子標的薬を併用し、これまでにない新しい有効な治療法の開発を試みる。

Outline of Final Research Achievements

Midline glioma, such as Diffuse Intrinsic Pontine glioma (DIPG), is unresectable and shows treatment resistance. Causative gene of DIPG was reported to be K27Mutation of H3F3A gene. Therefore, we isolated and established Saga 027 stem cells, which harbors the histone H3.3 Lys 27-to-methionine (K27M) mutation and can support research and drug development efforts targeting DIPG. Recently, it is reported that DRD2 is a G protein-coupled receptor that promotes tumor growth and has emerged as a therapeutic target for gliomas and other tumors that overexpress this receptor. ONC201 is a selective antagonist of dopamine receptor D2/3 (DRD2/3) that crosses the blood-brain barrier. We examined the effect of ONC201 for Saga 027 cells. However, these cells showed resistant against ONC201. Next, we examined various methylation inhibitors, and found effective usage of some drugs.

Academic Significance and Societal Importance of the Research Achievements

本研究ではこれらH3K27を標的とする薬剤を用いた治療効果を検討するとともに、ONC201を中心とした薬剤耐性のメカニズムを解析し、分子標的薬を併用することでより効果的な治療法の開発を試みた。 しかし、我々が確立した細胞株Saga027では、十分な効果が得られなかった。そこで、ある種のメチル化阻害剤の中で、有効な可能性があるコンパウンドを見出したことは今後の研究の発展が期待できるものと考えられた。
