Abstract
We investigated mechanisms of pancreatic cancer metastasis and defined the biological role of miR-29c in pancreatic cancer metastasis. After two rounds of cell selection in vivo, pancreatic cancer cells with various metastatic potentials derived from spontaneous liver metastases were used as a model of pancreatic cancer to determine the role of miR-29c in pancreatic cancer metastasis. Pancreatic cancer samples were analyzed for miRNA-29c expression, and these levels were associated with survival between groups. miR-29c suppresses cell migration and invasion by targeting the MMP2 3'UTR. Overexpression of miR-29c suppresses pancreatic cancer liver metastasis in a nude mouse orthotopic implantation model. miR-29c expression was associated with metastasis and pancreatic cancer patient survival. miR-29c plays an important role in mediating pancreatic cancer metastasis to the liver by targeting MMP2. Therefore, miR-29c may serve as a novel marker of pancreatic cancer metastasis and possibly as a therapeutic target to treat pancreatic cancer liver metastasis.
