In addition, Liu et al. provided evidence that the interplay between the signals of mechanistic target of rapamycin kinase (mTOR) and GPX4 modulates autophagy‐dependent ferroptosis in human pancreatic cancer cells, and the downregulated expression of GPX4 enhances the anti-cancer activity of rapamycin in vitro or in vivo by promoting ferroptosis and suppressing autophagy 38. This evidence concerns the gene GPX4 and cancer.
