| Outline of Final Research Achievements |
（１）In the invasion and metastasis model where mouse colon cancer cells are disseminated to the liver from spleen, we found two phase reaction of the host bone marrow-derived cells. In the early phase, neutrophils are recruited and in the late phase, fibrocytes. MMP9 and MMP2 are produced by these types of cells, respectively, which is critical for cancer invasion and metastasis.
（２）One of the genes induced by Notch signaling transcription in colon cancer cells is DAB1 of which product is tyrosine-phosphrylated by ABL kinase, which receiprocally activates ABL autophosphorylation. As a result, TRIO Y2681 is phosphorylated, which shows a strong correlation with poor prognosis as a novel diagnostic marker.
