miR-210 is closely related to the occurrence of pancreatic cancer. In addition, Runx3 is a tumor suppressor gene and inhibits tumorigenesis. However, miR-210's effect on Runx3 level is unclear. Therefore, Our study explored miR-210's effect on the proliferation and migration of pancreatic cancer cells. PANC-1 cell line was transfected with miR-210 Mimics or miR-210 Mimic + pFBD-Runx3 plasmids followed by analysis of miR-210 and Runx3 level by qRT-PCR, targeting relationship by the dual fluorescein reporter assay, Runx3 and Tubulin protein expression by Western blot, cell proliferation by MTT assay and cell migration by Transwell assay. Compared with normal tissue, miR-210 was significantly upregulated in pancreatic cancer tissue (P < 0.01), while Runx3 mRNA was significantly downregulated (P < 0.01). Runx3 was a target protein of miR-210. miR-210 Mimics transfection significantly reduced Runx3 level and increased cell proliferation, which was significantly reduced in the miR-210 Mimic + pFBD-Runx3 group. miR-210 Mimics significantly promote cell migration and the addition of Runx3 prevented miR-210 Mimics-induced cell migration. miR-210 binds to the 3'-UTR region of Runx3 mRNA, reduces Runx3 expression, and promotes cell proliferation and migration. Increased Runx3 can inhibit miR-210's effect on pancreatic cancer cells.
