Abstract
ETHNOPHARMACOLOGICAL RELEVANCE: The roots of Cudrania tricuspidata is a deciduous tree found in Korea, China, and Japan. C. tricuspidata contains an abundance of various minerals, B vitamins, and flavonoids to help prevent diverse cancers. Cudratricusxanthone A (CTXA), a compound isolated from the roots of C. tricuspidata, has potent anti-proliferative, antioxidative, and monoamine oxidase inhibitory effects. AIM OF THE STUDY: In the present study, cudratricusxanthone A (CTXA) is a xanthone isolated from the bioassay-guided fractionation of the EtOH extract of C. tricuspidata with strong anti-cancer activity in breast cancer cells. The effect of CTXA on cell migration and apoptosis were evaluated in the MCF-7 and MDA-MB-231 human breast carcinoma cell lines. MATERIALS AND METHODS: Effects of CTXA on phorbol 12-myristate 13-acetate (PMA)-induced MCF-7 and MDA-MB-231 cells. Flow cytometric measurements of CTXA-induced apoptosis in breast cancer cells. RESULTS: The results show that CTXA gradually reduced viability of the two breast cancer cell lines and induced apoptosis in a concentration-dependent manner. Moreover, CTXA effectively blocked breast cancer cell migration and invasion. CTXA decreased the expression of matrix metalloproteinase-9, extracellular regulated kinases 1 and 2 and phosphorylation of the inhibitor IκBα in the MCF-7 and MDA-MB-231 cell lines. CONCLUSIONS: Collectively, these results indicate that CTXA possesses anti-cancer activities and provide a basis for developing effective therapeutic agents to inhibit growth and metastasis of breast cancer.
