Outline of Final Research Achievements

Please see the attached files. We extracted RNA from tumor tissues of colorectal cancer (CRC) patients. We ordered miRNA microarray, and we identified 11 high budding grade specific dysregulated miRNAs. Then, we investigated the association between the relative expression of each miRNAs and tumor budding grade by using qRT-PCR in testing and validation CRC cohort. As we expected, all of the expression of 11 miRNA were significantly low high-budding grade CRC patients in each clinical cohort.

Academic Significance and Societal Importance of the Research Achievements

Tumor budding gradeは非常に有用な指標でありながら、内視鏡治療手術標本に基づいて評価されており、大腸癌患者の治療前の戦略に大きく影響していないのが現状であり、high tumor budding gradeを予測しうる分子生物学的バイオマーカーの開発・発展が望まれる現状である。
