SOX2 and gastric cancer: To assess whether Ginsenoside Rg3 inhibited the expression of SOX2 and the PI3K/AKT/mTOR signaling axis in cisplatin-resistant GC cells, AGSR-CDDP cells were incubated with Ginsenoside Rg3 and the transcript levels of SOX2 and the PI3K/AKT/mTOR signaling axis were determined by RT-qPCR.
