Outline of Final Research Achievements |
Using the proteome data obtained from mass spectrometry, we performed protein co-expression analysis and succeeded in identifying important molecular profiles, co-expression networks linked to prognosis, and analyzing upstream regulators. In addition to aerobic glycolysis, it was revealed that the non-canonical Hedgehog pathway controlled by GLI1, cap-independent translation by IRES, IRE1a/XBP1 pathway, inactivation of the UPR pathway, activation of SOX2, and mutations in PALB2 are involved in the biological malignancy of pancreatic cancer.

Academic Significance and Societal Importance of the Research Achievements |
膵癌において同様の進行度であっても、生物学的悪性度が異なり、治療反応性、転移進展経路、予後も異なる。これまでにも様々な研究が進められてきたが、さらなる病態の解明には改めて網羅的俯瞰的な解析も重要である。今回我々は新規のタンパク質共発現解析により、予後に結び付いた共発現ネットワークの同定、上流制御因子を解析することに成功した。膵癌に対する新たな治療戦略開発の第1歩となると思われた。
