Outline of Research at the Start

ヒトの腸内には数千種、100兆個もの腸内細菌が生息し、他の種類の腸内細菌との間で数のバランスを保ちながらひとつの生態系を形成している。腸内細菌はヒトの健康維持に欠かせない役割を持つ一方、菌組成のバランスが崩れた場合には大腸がんを含む様々な疾患の要因にもなる。本研究代表者らが大腸がん患者の糞便を用いて行った研究では、大腸がんの初期段階であるポリープや粘膜内がんを有する患者の糞便中に硫黄細菌やアミノ酸腐敗菌が多く検出された。本研究では、これらの細菌が発がんの要因であることを定量的に明らかにするため、大腸がん患者の粘膜生検(腫瘍部位と正常部位)を用いたメタゲノム・メタトランスクリプトーム解析を行う。

Outline of Final Research Achievements

In this pilot study, we aimed to establish a methodology for metagenomic analysis using colorectal endoscopic biopsy samples to quantitatively analyze the functional characteristics of gut microbiota localized in small lesions, such as polyps and intramucosal carcinoma, which are considered precancerous lesions of colorectal cancer. As a result, we successfully extracted bacterial DNA from colorectal mucus and performed metagenomic analysis.

Academic Significance and Societal Importance of the Research Achievements

本研究の学術的意義は、大腸がんの初期段階における腸内細菌の役割をゲノムの視点から解明するための大規模データ解析の基盤を創出するところにある。特に、大腸がん患者由来の粘膜生検試料のメタゲノム解析は世界的に高いインパクトがある。以上の研究は腸内細菌の基礎的な理解を深めるだけでなく、将来的には、発がんの原因となる菌を標的とした新たな治療薬の開発や、原因菌の除去などのがん予防策の開発が期待できる。
