Outline of Research at the Start

がんの転移・浸潤・薬剤耐性などの悪性化には腫瘍微小環境が重要な役割を果たす。本研究では、グルタミン欠乏を基軸としたがん細胞のアミノ酸欠乏のアダプティブセンサーの探索から新規がんの治療法の開発につながる研究を目的とする。本研究は、がん研究のみならず、アミノ酸代謝疾患研究、mTOR研究やオートファジー研究などの学術体系の変革や転換にも繋がる可能性を有し、アミノ酸代謝疾患の制御にも応用可能な研究である。

Outline of Final Research Achievements

The tumor microenvironment plays an important role in malignant transformation such as growth, metastasis and drug resistance of cancer cells. The purpose of this study was to identify adaptive sensors to amino acid deficiency in cancer cells, inhibition of which can be utilized for the development of novel cancer treatments. We conducted researches on (1) exploration of adaptive sensors for amino acid deficiency and (2) elucidation of the adaptive mechanism of cancer to amino acid deficiency. We identified glutamine and other amino acid-specifically induced genes, histone modifications (H3K4me3, H3K27ac), promoters, enhancers, and possible upstream regulators. We identified candidate of sensors and regulators that are essential for amino acid deficiency, such as transcription factors and amino acid transporters.

Academic Significance and Societal Importance of the Research Achievements

近年、がん細胞はロイシンなどの必須アミノ酸をmTOR複合体を介したシグナル伝達系で感知することが知られている。一方、グルタミンなどのアミノ酸欠乏感知機構は未だ不明な点が多い。本研究は、独自の低栄養培養やアミノ酸培養系を作成し、各アミノ酸で特異的に発現誘導される遺伝子群やエピゲノム制御機構を同定、各アミノ酸における上流転写因子を同定など、がん細胞の新規アミノ酸欠乏アダプティブ機構が存在する可能性を見出した。本研究により、がん悪性化を促進する新しいアミノ酸欠乏の感知・適応システムやアミノ酸代謝異常に関わる代謝経路や遺伝子変動の解明が可能となり、今後、新規がん治療法への応用が期待できる。
