Objective: To investigate the effect of Tinospora crispa (T. crispa) extract on matrix metalloproteinase-13 (MMP-13) expression and cell migration. Methods: The cytotoxicity of T. crispa extract was examined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay on head and neck squamous cell carcinoma (HNSCC) cell lines. The effect on expression of MMP-13 was analysed by RT-PCR and ELISA. The migration was assessed by wound healing assay. Results: MMP-13 mRNA was highly expressed in the metastatic human HNSCC cell lines, HN22 and HSC-3. T. crispa extract at a concentration of 100.0 μg/mL caused about 50% reduction of cell survival. T. crispa extract at a non-toxic concentration of 12.5, 25.0 and 50.0 μg/mL significantly suppressed MMP-13 mRNA expression and secreted MMP-13 in both HN22 and HSC-3. The expression of tissue inhibitors of metalloproteinase-2 (TIMP-2) by HSC-3 cells was attenuated by 25.0 and 50.0 μg/mL of T. crispa extract. Addition of the extract to cells in a wound healing assay showed inhibition of cell migration by HN22 cells. Conclusions: These data suggest that T. crispa could be considered as a potential therapeutic drug to prevent metastasis of HNSCC.
