Outline of Final Research Achievements

In this study, we conducted comprehensive methylation analysis using surgical specimens from sporadic colorectal cancer or ulcerative colitis-associated CRC, and successfully identified cancer-specific hypermethylated CpG site. Furthermore, we validated this CpG site using pyrosequencing, and showed that quantification of methylation levels using non-neoplastic rectal mucosa could identify high-risk UC patients for CRC.

Academic Significance and Societal Importance of the Research Achievements

今回、潰瘍性大腸炎における様々な部位の大腸粘膜におけるメチル化の程度を明らかにし、さらに内視鏡検査にて簡便に評価可能かつ肛門鏡で生検可能な直腸粘膜を用い、そのメチル化のField effect/cancerizationを用いた大腸全体の癌化の状況を判別する概念を確立することはこれまでにない新しいアプローチとなる。
