MicroRNAs (miRNAs) are known to be associated with certain cancers, including osteosarcoma. We examined osteosarcoma tissues and cell lines, and found that most expressed lower levels of miR-548d-3p than adjacent tissues and normal cell lines. KRAS was identified as a potential target gene of miR-548d-3p. In osteosarcoma cells, miR-548d-3p exerted tumor-suppressive effects by downregulating KRAS. Functional assays revealed that miR-548d-3p mimics dramatically reduced cell growth and migration in vitro. These results suggest that miR-548d-3p mimics could be applied for osteosarcoma treatment.
