Outline of Final Research Achievements

We searched the molecular mechanisms of gastric adenocarcinoma caused by EBV infection. After EBV infection, cellular senescence was not observed, but accumulation of specific subclones was observed by clone tracing with DNA barcodes. From single cell RNA-sequencing, the original cell population was found to consist of three sub clusters and one of which contained the subclones accumulated during EBV infection. We also determined marker genes which characterized this sub-population.

Academic Significance and Societal Importance of the Research Achievements

本研究から、均質に見える胃正常細胞においても不均一性が存在し、EBウイルスの感染・維持に有利な細胞集団の存在が示唆された。どの細胞がEBウイルスに感染するのかについてはこれまで不明であったが、そのマーカーとなりうる遺伝子を抽出できたことは発癌機構を明らかにする上で有益である。90%以上の成人がEBウイルスに感染しているとされるが、今後、易感染性細胞の性質を明らかにすることで、胃癌発症のリスクを抑える予防法の開発が進むと期待される。
