Outline of Final Research Achievements

We focused on transcription factor Snail, which plays a central role in Epithelial-Mesenchymal transition (EMT). In Snail-depleted mouse ovarian cancer, the tumor growth was inhibited. Snail induced the expression of chemokines such as CXCL1 and CXCL2, and increased the infiltration of Myeloid-derived suppressor cells (MDSC) in tumor microenvironment. High concentration of CXCL1/2 was found in ovarian cancer patients' serum. CXCL1/2 was also associated with poor prognosis and high number of MDSCs in the tumor.

Academic Significance and Societal Importance of the Research Achievements

これまで上皮間葉転換(EMT)は癌の進展や転移に関連があることが知られていたが、免疫との関連はよくわかっていなかった。今回、EMTが起こっているときに、SnailによるCXCL1/2の発現を通して、免疫抑制性細胞のMDSCが腫瘍内に浸潤してくることを初めて示し、EMTが免疫抑制と関連していることを示した。また、担癌患者のCXCL1/2の血清中濃度を測定することで、腫瘍内のMDSC数といった免疫状態を推定することが可能であることが示唆され、CXCL1/2の腫瘍免疫バイオマーカーとしての価値も確認された。
