Outline of Final Research Achievements |
The imbalance of commensal gut microbiota is known to be a risk factor for various diseases such as cancer, inflammatory bowel disease, allergies, and obesity. The purpose of this study is to elucidate the molecular mechanisms of gut microbiota-mediated host gene expression. We performed RNA-seq analysis with mice in a normal environment and germ-free mice lacking gut microbiota. We found that mice in a normal environment exhibited increased expression levels of interferon-stimulated genes compared to germ-free mice.

Academic Significance and Societal Importance of the Research Achievements |
腸内細菌叢と宿主は密接な共生関係にあり、腸内細菌が宿主の健康に様々な良い影響を与える一方で、その乱れは病気の発症と関連する。腸内細菌が引き起こす病気のメカニズムを理解するためには、腸内細菌が宿主に与える影響の分子基盤を解明する必要がある。本研究により明らかにされた、腸内細菌によって誘導される宿主の遺伝子発現変化は、腸内細菌が原因となる様々な病気の治療法の開発に役に立つ可能性があり、社会的意義が高いと言える。
