Outline of Research at the Start

神経芽腫は白血病、脳腫瘍、リンパ腫にならんで死亡率が高い小児がんであり、有効な治療法の開発が望まれている。悪性度の高い神経芽腫細胞ではプロモーター領域に存在するCpGアイランドのメチル化状態が乱れていることが報告されている。そこで本研究では、神経芽腫細胞株および神経芽腫自然発生モデルマウスを用いて神経芽腫の悪性化に関与するDNAメチル化酵素を同定し、その役割を解明することで、新規治療法の開発に繋げることを目的とする。

Outline of Final Research Achievements

Analysis of clinical specimens demonstrated that DNMT3B exhibits high expression in high-risk groups, and its expression level is closely associated with prognosis. Additionally, we observed that suppressing DNMT3B through siRNA or small molecule compounds effectively exerts an antitumor effect on neuroblastoma. Specifically, DNMT3B inhibition induced global demethylation and apoptosis in neuroblastoma cells. Furthermore, RNA-seq analysis indicated that DNMT3B inhibition enhances the expression of genes within the p53 pathway.

Academic Significance and Societal Importance of the Research Achievements

神経芽腫の予後不良群に対しては未だ有効な治療法が確立されていないことから、有効性が高く副作用の少ない治療法を開発することが待ち望まれている。本研究により、DNMT3Bが神経芽腫の進行に関与すること、DNMT3Bの阻害が神経芽腫に対して抗腫瘍効果を発揮することが示唆された。今後DNMT3Bに対してより詳細な検討 (in vivo実験など) を行うことで、新たな治療法の開発に繋がる可能性がある。
