| Outline of Final Research Achievements |
The molecular mechanisms of progression and metastasis must be elucidated to cure metastatic colorectal cancers (CRCs). In this study, we established a new culture condition of colorectal cancer cell lines to generate elevated microsatellite alterations at selected tetra-nucleotide (EMAST). EMAST is a type of genomic instability and frequently detected in poor prognosis CRCs. Therefore, the in vitro EMAST generating condition is thought to reflect in vivo tumor microenvironment for malignant progression. Under this condition, we identified several genes with no apparent relevance to CRC by a comprehensive analysis of genes expression. Caveolin-1 (CAV1) was a candidate for novel malignant CRC-relating protein, because it was also detected in clinical CRC samples. Although precise roles of identified genes, including CAV1, were not reveled, our established EMAST-gerating culture condition was shown to be useful for a screening of malignant CRC-relating factors.
