Garcinol regulates EMT and Wnt signaling pathways in vitro and in vivo, leading to anticancer activity against breast cancer cells.

Anticancer properties of Garcinia indica-derived garcinol are just beginning to be elucidated. We have earlier reported its cancer cell-specific induction of apoptosis in breast cancer cells, which was mediated through the downregulation of NF-κB signaling pathway. To gain further mechanistic insight, here, we show for the first time that garcinol effectively reverses epithelial-to-mesenchymal transition (EMT), that is, it induces mesenchymal-to-epithelial transition (MET) in aggressive triple-negative MDA-MB-231 and BT-549 breast cancer cells.
