Outline of Final Research Achievements

In the present study, metabolite analysis was performed by MALDI-MSI on pancreatic cancer tissues and pancreatic cancer microenvironment reproduction models. We tried to detect metabolites specific to cancer - stromal interaction and stromal remodeling. The three-dimensional co-culture system clarified the mechanism of pancreatic stellate cells remodeling the stroma by Endo 180. In addition, for performing MALDI-MSI on frozen sections, we developed pancreatic cancer organoid models reflecting the tumor microenvironment derived from human pancreatic cancer. From now on, we will perform metabolome mapping by MALDI-MSI using the model, and continue to search for metabolites characteristic of the stromal remodeling.

Academic Significance and Societal Importance of the Research Achievements

従来の質量分析法では、代謝物の抽出・濃縮が不可欠で組織内局在情報が失われてしまうが、マトリックス支援レーザー脱離イオン化質量分析イメージング(MALDI-MSI)を用いることで、メタボローム情報を組織上にマッピングすることが可能となった。本研究は、膵癌組織および3次元培養モデルに対するMALDI-MSIを用いた代謝物解析、間質リモデリングに特徴的な因子の同定を行った。膵癌組織に特徴的な代謝産物を同定し、そのメカニズムを明らかにすることによって早期診断・新規治療法確立の手がかりを探ることにつながると考えられる。
