Outline of Final Research Achievements |
We previously reported that mRNA-binding protein-bound transcripts accumulate in membrane protrusions of pancreatic ductal adenocarcinoma (PDAC) cells, and the formation of additional membrane protrusions increased the invasive and metastatic properties of the PDAC cells. In the course of this investigation, we picked up the three mRNA-binding proteins; Var3, PODXL and CCDC88, and demonstrated that these candidate markers were accumulated in cell protrusions, contributed to the formation of membrane protrusions, and increased the migration and invasiveness of PDAC cells. In contrast, knockdown of each of them inhibited the motility and invasiveness of PDAC. Immunohistochemistry leveled that high expression of these proteins was an independent predictor of worse overall survival of pancreatic cancer patients. Our studies suggest that they can be a useful marker for predicting the outcome of patients with PDAC and thereby increased the motility and invasiveness of PDAC.
