| Outline of Final Research Achievements |
Specific miRNAs to be methylated and DMRs in rectal mucosal in patients with UC could be used to identify patients with UC at greatest risk for developing UC-CRC. Fusobacterium infection was detected in CRC tissues. Furthermore, Fusobacterium infection was significantly associated with MSI-H compared to non-MSI-H. Unfortunately, it is difficult to detect the oral microbiota and we could not process comprehensive analysis of oral microbiota.

| Academic Significance and Societal Importance of the Research Achievements |
本研究結果を用いることで、潰瘍性大腸炎患者における潰瘍性大腸炎関連大腸癌の発癌予測マーカーとなり得るほか、MSI－H大腸癌における発癌機序に腸内細菌が関与している新たな可能性が示唆された。
