| Outline of Final Research Achievements |
In this study, we found that adiponectin receptor agonist AdipoRon induces cell death in pancreatic cancer cells and clarified the molecular mechanism. In pancreatic cancer cells, AdipoRon activates ERK1/2 via adiponectin receptor AdipoR1, followed by accumulation of calcium and increased production of superoxide in mitochondria, to induce necroptosis by inducing mitochondrial dysfunction. In addition, AdipoRon suppressed tumor growth without serious side effects by oral administration to pancreatic cancer-bearing mice, and showed a cell killing effect on cancer cells derived from patients with pancreatic cancer.

| Academic Significance and Societal Importance of the Research Achievements |
本研究では、AdipoRonがヒト膵がん細胞の細胞死を誘導する分子機序を明らかにするとともに、動物実験や膵がんの臨床検体を用いたアッセイでもAdipoRonが膵がんに対する抗腫瘍効果を示すことを明らかにした。AdipoRonは抗糖尿病薬としての臨床応用が期待されているが、これまでがん治療への応用は試みられていない。本研究により得られた新たな知見は、アディポネクチン受容体アゴニストを膵がん治療に応用するための科学的な根拠となりうる。
