Outline of Research at the Start

腫瘍浸潤、がん幹細胞性と糖代謝改変(Warburg効果)はがん治療耐性獲得の主要因であるが、これまでは個別の悪性形質として研究されてきた。本研究は抗がん剤耐性を獲得した膵がん細胞とマウス同所移植腫瘍を対象に、これらの悪性形質に共通して作用する細胞のしくみ(分子経路)を究明する。これにより、膵がん治療が直面している抗がん剤耐性獲得という難題を解明し、その効果的な治療法開発の基盤となる知見を得ることを目的とする。

Outline of Final Research Achievements

Refractory pancreatic cancer is typified by high invasiveness and resistance to therapy, with both attributes related to tumor cell stemness and glycolytic metabolic reprogramming (aerobic glycolysis). We previously identified glycogen synthase kinase (GSK)3β as a distinct tumor-promoting kinase. This study found the central role of GSK3β as a molecular hub that mechanistically integrates tumor cell invasion, stemness and aerobic glycolysis in pancreatic cancer acquiring chemoresistance. Overall, GSK3β has characteristics of a promising therapeutic target against chemoresistance in pancreatic cancer.

Academic Significance and Societal Importance of the Research Achievements

腫瘍浸潤、がん幹細胞性と糖代謝異常はがん治療耐性の主要因であるが、これまでは個別の悪性形質として研究されてきた。本研究は、GSK3βがこれらの悪性形質を結びつけて膵がんの抗がん剤耐性化に作用することを究明した。このようなGSK3βによる膵がん悪性形質を促進する仕組みは、本酵素を標的とするがん治療法開発の基盤を強化する。
