Outline of Final Research Achievements

Despite advances in cancer therapeutics, more than 370,000 people die due to cancers per year in Japan. In other words, more than 370,000 people are forced to live with incurable cancers. Such incurable cancers adversely affect the host in various manners. For example, patients with incurable cancers show reduced appetite, weight loss, impaired therapeutic efficacy, and so on. These symptoms are clinically known as cancer cachexia. Yet, no effective therapeutics on cancer cachexia have been available to date. This study reveals a novel host factor that mediates abnormalities in the adipose tissues in cancer cachexia.

Academic Significance and Societal Importance of the Research Achievements

根治不能ながんの症例数に鑑みると、がんを根治できない場合にどのようにすべきかを考えることは重要であるように思われる。本研究の進展によって、がん悪液質の病態を制御できる方法の確立へと至れば、患者の生活の質や治療感受性を向上させる手法論の開発へとつながると期待できる。また、本研究で発見した因子に依らない症状・表現型を炙り出し、その責任因子を探る、というアプローチにより、がん悪液質という複雑な病態を宿主遺伝子の立場から整理できるようになる。以上、本研究は、がん悪液質という課題について、臨床・基礎の両面で進展をもたらすものであると考えている。
