Abstract:
Objective To investigate the role of miR-429 in osteosarcoma stem cells.Methods We employed different approaches to test the expression of miR-429 in osteosarcoma stem cells.miR-429-high and miR-429-low cells were separated using molecular probes and their stem cell-like properties were compared.The effect of miR-429 on osteosarcoma stem cell-like properties was further tested through transfection assays.Furthermore,the miR-429 downstream target gene was confirmed by luciferase assay.Results The expression of miR-429 in osteosarcoma stem cells was much lower than that in control cells.miR-429-high cells displayed fewer stem celllike properties than did miR-429-low cells.These observations were confirmed by transfection assays.Additionally,our luciferase assays showed that miR-429 regulates Sox2 at the post-transcriptional level.Conclusion miR-429 negatively regulates osteosarcoma stem celllike properties by targeting Sox2.
