Ginsenoside Rg6 Improves Cisplatin Resistance in Epithelial Ovarian Cancer Cells via Suppressing Fucosylation and Inducing Autophagy

/M-cell cycle arrest was proven to result from the autophagy of cDDP-resistant EOC cells. In addition, we observed that G-Rg6 initiates autophagy in cDDP-resistant EOC cells by inhibiting the GRB2-ERK1/2-mTOR axis, and that high concentration of G-Rg6 treatment leads to cell apoptosis. G-Rg6 also enhances cDDP uptake in A2780CP cells by promoting CTR1 expression and suppressing its core fucosylation. Therapies combining cDDP and G-Rg6 display higher efficacy in inhibiting the cDDP-resistant EOC cells in comparison with the sole application of cDDP, exhibiting strong potential for clinical application. G-Rg6 derived from the American ginseng berry can improve cDDP resistance in EOC cells via suppressing fucosylation and inducing autophagy, suggesting its potential in the adjuvant chemotherapy of EOC patients.
