Outline of Final Research Achievements

We identified a Plastin3 (PLS3) that was only detectable in the metastasis by comprehensive genetic analysis using a sample of colon cancer cases. It was confirmed that cancer cells introduced PLS3 were promoting the epithelial-mesenchymal transition (EMT) and the cancer stem cells.
Cancer cell-killing effect of cytotoxic T cell was reduced. Because the binding of PD-L1 on cancer cell to PD-1 on lymphocyte transmits an inhibitory signal which reduces the proliferation of cytotoxic T cells. High expression of both HLA class I and PD-L1 had a high recurrence rate and poor prognosis.
