Outline of Final Research Achievements

It has been reported that the interaction between stromal cells and cancer cells plays an important role for metastasis in colorectal cancer. However,their molecular mechanisms are largely unknown. In this study, the purpose is to clarify the role of stromal cells in colorectal cancer metastasis. We tried to establish a colorectal cancer metastasis model using zebrafish and an insertion mutation transduction system using transposon, and to identify and perform functional analysis of the genes for colorectal cancer metastasis promoting or suppressing in stromal cells. However, we have not identified the genes yet.

Academic Significance and Societal Importance of the Research Achievements

大腸がん患者の死因の多くは、遠隔転移に起因する割合が最も高く、大腸がんの死因の約1/3を占めるが、現段階では、遠隔転移の早期診断法や有効な治療法もない。その理由の一つは、大腸がん転移メカニズムが解明されていないためである。つまり、転移メカニズムの解明は、転移の早期診断法や有効な治療法を開発するための有益な情報となる。
