Outline of Final Research Achievements |
Genetic analysis using a 3D culture system of pancreatic cancer cells identified MUC1 as a factor that exhibits a similar molecular expression pattern to PSCA, which is involved in pancreatic cancer metastasis. The expression of MUC1 was also shown to be regulated by PSCA, and it was also found to be a poor prognostic factor for pancreatic cancer patients, just like PSCA. Furthermore, we constructed a vector set necessary for the construction of a exosomal quantitative evaluation system targeting for surface markers, and a exosomal qualitative evaluation system targeting for exosome-containing EPS8 in pancreatic cancer cells. We established a luminescence gene knock-in cells to the end of CD63 coding sequences in pancreatic cancer cells, which is able to evaluate the production of exosome quantitatively.

Academic Significance and Societal Importance of the Research Achievements |
膵臓がんは未だ予後不良のがんであり、その治療も限られている。新たな治療法の開発が必要であり、その標的因子の探索は重要な研究テーマである。本研究では、近年、臨床を比較的に反映していると評価されている3D培養を用いて、新たな視点から膵臓がんの転移・悪性化制御因子の同定を行なった。また、膵臓がん転移に重要なエクソソームについて、質的・量的な活性評価を3D培養細胞で行うことが可能な技術開発を行なった。また、活性評価系に適した漢方薬のライブラリー作製も行なった。本成果により、新たな観点に基づいた漢方薬による膵臓がん治療の可能性について、評価可能となったものと考えられる。
