Outline of Research at the Start

口腔癌の治療においては、本邦で行われている動注化学併用療法は極めて高い局所制御率を誇るが、癌転移が予後を不良にしており、特に遠隔転移の防止は治療成績向上に向けての喫緊の課題である。一方、癌細胞のヒアルロン酸産生が遠隔転移に関連していることが確かめられている。従って、ヒアルロン酸合成阻害剤と放射線の効果の基礎的機能解析を行い、作用機序を解明し、ヒアルロン酸合成阻害薬併用による新たな放射線治療の確立を目指す。

Outline of Final Research Achievements

As an attempt to eradicate radioresistant cells generated during radiotherapy, we investigated the effect of 4-methylumbelliferone (4-MU), a hyaluronan synthesis inhibitor, in combination with radiation. As a result, 4-MU administration suppressed cell survival rate and cell migration, suppressed cancer stem cell-like phenotype, and enhanced oxidative stress. When HAS3, which was highly expressed in radioresistant cells, was targeted and knocked down by siRNA, suppression of cell viability and enhancement of radiosensitization effect were observed. These results suggest that HAS3 is an important factor in radiation resistance, and that direct inhibition of HAS3 or inhibition of hyaluronic acid synthesis may enhance the radiosensitizing effect.

Academic Significance and Societal Importance of the Research Achievements

放射線治療は、近年の高精度照射技術の発展によって治療適応が拡大し、癌治療において重要な位置を占めている。しかし標準的放射線治療では癌細胞集団の一部が放射線抵抗性を獲得し、再発や遠隔転移を引き起こすことが問題視されている。放射線抵抗性細胞に有効な薬剤や治療戦略は未だ確立されていないため、放射線治療の予後改善のためにこの課題解決は急務である。ヒアルロン酸合成阻害剤として知られている4-メチルウンベリフェロンは、様々な癌細胞で抗腫瘍/転移効果を示すことが報告されている。そこで本研究では、放射線抵抗性腫瘍細胞株を使用し、4-メチルウンベリフェロンと放射線との併用効果を研究した。
