ETHNOPHARMACOLOGICAL RELEVANCE: Antrodia camphorata (AC) is a well known traditional Chinese medicinal mushroom in Taiwan, has been used to treat various diseases including cancer.
MATERIALS AND METHODS: In this study, we investigated the anti-metastatic and anti-EMT properties of a fermented culture broth of AC in human colon SW480and metastatic SW620cancer cells in vitro.
RESULTS: AC down-regulates claudin-1 and inhibits the proliferation and colony-formation abilities of both SW620and SW480cells. In highly metastatic SW620cells, non-cytotoxic concentrations of AC significantly inhibited migration/invasion, accompanied by the down-regulation of MMP-2 and MMP-9 proteins. AC decreased nuclear translocation of Wnt/β-catenin through a GSK3β-dependent pathway. AC consistently inhibited EMT by up-regulating the epithelial and downregulating the mesenchymal marker proteins. In SW480cells, AC suppressed migration/invasion potentially through the inhibition of the PI3K/AKT/NFκB signaling pathways without altering the expression levels of β-catenin and GSK3β proteins.
CONCLUSION: Altogether, this study demonstrates the anti-metastatic and anti-EMT activities of AC, which may contribute to the development of a chemopreventive agent for colon cancer.
