Background: Osteosarcoma is one of the most malignant cancers in children. Naringenin exhibits several cellular functions. Objectives: In this study, we investigate the effects of naringenin on osteosarcoma. Materials and Methods: 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetra zolium bromide (MTT) assay was performed to detect the cell viability. Zymography assay and transwell assay were used to measure the matrix metalloproteinase (MMP) activity and migration ability. Western blot analysis was used to determine the expression of migration-related proteins. Results: No overt alternation of cytotoxicity in response to different concentrations of naringenin for 24 h was found by MTT assay. MMP-2 and MMP-9 activities and expression were significantly repressed by naringenin in a dose-dependent manner, as evidenced by zymography and Western blot analysis. Naringenin dose dependently reduced the expression of mesenchymal marker Snail. Conclusion: These results indicate that naringenin exhibited antimigration property through inhibition of MMP-2 and MMP-9 and downregulation of Snail expression. Thus, naringenin may be a potential inhibitor of metastasis of osteosarcoma.
