    Abstract:
    OBJECTIVE: To dissect the functioning mode of miR-30c on giant cell tumor of bone cell metastasis and growth and provide therapeutic targets for giant cell tumor of bone. PATIENTS AND METHODS: By quantitative Real-time polymerase chain reaction (qRT-PCR), miR-30c expression level in 62 pairs of giant cell tumor of bone cells tissue samples and five breast cancer-derived cell lines. Using miR-30c mimics and inhibitors, we analyzed the effects of miR-30c over-expression and knockdown on cell proliferation, invasion, and migration. Dual-luciferase activity assay was recruited to examine the potential target gene HOXA1, which predicted by several databases. Protein level was studied using Western blot. RESULTS: MiR-30c expressed significantly lower in giant cell tumor of bone tissue samples and cell lines. Over-expression miR-30c in giant cell tumor of bone cells decreased the cell proliferation, invasion, and migration abilities while down-regulation miR-30c in giant cell tumor of bone cells increased these abilities oppositely. Dual-luciferase and Western blot confirmed HOXA1 as a target gene of miR-30c. Furthermore, up-regulation of HOXA1 reserved the suppressive effect of miR-30c over-expression on cell growth and progression. CONCLUSIONS: miR-30c could suppress giant cell tumor of bone cell proliferation and progression via HOXA1, which might provide a new target for giant cell tumor of bone diagnosis and therapy.
