Outline of Final Research Achievements |
We analyzed intrinsic properties of a clone established form dormant bone marrow-disseminated tumor cells (BM-DTC) using mouse xenograft model. Then, we found that the dormant BM-DTC clone had a gene expression signature distinct from lung metastasis- and inoculation site-derived clones. Furthermore, our DNA barcoding assay indicated that dormant BM-DTC consisted of specific populations, and we identified a clone which would preferentially occupy dormant BM-DTC.

Academic Significance and Societal Importance of the Research Achievements |
癌による死亡のほとんどは転移・再発を原因とする。様々な癌において、患者骨髄で増殖せずに潜伏している癌細胞が検出された場合、その後の転移・再発が多いことは疫学的に確立している。マウスモデルを用いた本研究によって、骨髄で潜伏している癌細胞が、特有の癌細胞集団によって占められていることが示唆された。さらに、その起源となりうる癌細胞クローンを一つ同定することができた。今後、同定したクローンを解析していくことで、癌細胞の播種過程や増殖再開メカニズムの理解が進み、新たな治療法の開発に寄与するものと期待される。
