The study demonstrates that platyphyllenone significantly inhibits the motility, migration, and invasion of oral cancer cells by modulating specific proteins and signaling pathways, indicating its potential as an anti-metastatic agent in oral cancer treatment.
Advanced-stage oral cancers with lymph node metastasis are associated with poor prognosis and a high mortality rate. Although recent advancement in cancer treatment has effectively improved the oral cancer prognosis, the majority of therapeutic interventions are highly expensive and are associated with severe sideeffects. In the present study, we studied the efficacy of a diarylheptanoid derivative, platyphyllenone, in modulating the metastatic potential of human oral cancer cells. Specifically, we treated the human oral cancer cells (FaDu, Ca9-22, and HSC3) with different concentrations of platyphyllenone and measured the cell proliferation, migration, and invasion. The study findings revealed that platyphyllenonesignificantly inhibited the motility, migration, and invasion of human oral cancer cells. Mechanistically, platyphyllenone reduced p38 phosphorylation, decreased beta-catenin and Slug, increased E-cadherin expression, and reduced cathepsin L expression, which collectively led to a reduction in cancer cell migration and invasion. Taken together, our study indicates that platyphyllenone exerts significant anti-metastatic effects on oral cancer cells by modulating cathepsin L expression, the MAPK signaling pathway, and the epithelial-mesenchymal transition process.
