As mentioned above, these miRNAs such as miR-203, miR-204, miR-205 and miR-217 negatively regulate RUNX2 expression, raising a possibility that miRNA-induced down-regulation of RUNX2 contributes to the suppression of malignant properties of pancreatic cancer cells such as drug resistance (Fig. 4). The gene discussed is RUNX2; the disease is pancreatic neoplasm.
