Chrysanthemum zawadskii Herbich var. latilobum Kitamura (Compositae), colloquially known "Gujulcho" in Korea, has been used in traditional medicine for the treatment of various diseases, including cough, common cold, bladder-related disorders, gastroenteric disorders, hypertension, and inflammatory diseases, such as pneumonia, bronchitis, pharyngitis, and rheumatoid arthritis (RA) However, the effect of Chrysanthemum zawadskii var. latilobum on breast cancer invasion is unknown. In this study, we investigated the inhibitory effect of Chrysanthemum zawadskii var. latilobum extract (CZE) on 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced matrix metalloproteinase-9 (MMP-9) expression and cell invasion, as well as the molecular mechanisms involved in MCF-7 cells. CZE were not cytotoxic up to 100 ${\mu}g/ml$ concentration in the MCF-7 cell line. CZE decreased MMP-9 expression. TPA substantially increased NF-${\kappa}B$ DNA binding activity. Pre-treatment with CZE inhibited TPA-stimulated NF-${\kappa}B$ binding activity and NF-${\kappa}B$ related protein expression. To identify invasion ability of MCF-7 cells decreased by CZE, we used martrigel invasion assay. As a result, it is significantly decreased cell invasion. These results indicate that CZE-mediated inhibition of TPA-induced MMP-9 expression and cell invasion involves the suppression of the NF-${\kappa}B$ pathway in MCF-7 cells. Chrysanthemum zawadskii var. latilobum may have potential value in restricting breast cancer metastasis.
