SLC7A11 and gastric cancer: Cystine/glutamate reverse transporter SLC7A11 is a membrane channel transporter protein that can increase the synthesis of L-glutathione (GSH) in GC cells, help cancer cells resist ferroptosis-induced reactive oxygen species(ROS)and iron accumulation, enable GC cells to survive under hypoxic conditions, and promote peritoneal metastasis (PM) of GC (58, 59) (Figure 2).
