Outline of Final Research Achievements

Pancreatic cancer has been an aggressive malignancy. Recently, stroma in tumor is reported to be associated with cancer-cell proliferation, apoptosis, differentiation, and invasion in several cancers. Previously, CRMP4 staining was highly correlated with poor differentiation and liver metastasis. In mouse model, previous study revealed that caerulein-induced pancreatitis augments the expression of CRMP4. In current study, we investigated the role of CRMP4 in pancreatic cancer precursor lesions in gene engineered mouse model. Our results suggested that CRMP4 is significantly associated with initiation and progression of pancreatic cancer.

Academic Significance and Societal Importance of the Research Achievements

膵癌は早期から周囲臓器への浸潤や遠隔転移を認める特徴がある。浸潤、転移を抑制する治療法が確立されたならば、既存の治療法との相乗効果が見込まれ、治療成績の向上が期待できる。膵癌におけるCRMP4の制御機構を解明することは、膵癌の新規治療薬を開発していく上で極めて重要である。本研究によりCRMP4ノックアウトマウスと、LSL-KrasG12DマウスとPdx1-Creマウスを掛け合わせて膵癌モデルマウスを作成することに成功した。CRMP4ノックアウトマウスを用いた膵癌発癌モデルの報告はなく、世界的に例のない独自の研究である。膵前癌病変、膵癌におけるCRMP4の役割を検証することが可能となった。
