For example, Chen et al. (2020a) and Chen et al. (2020b) recently reported on the role of GDF15 in gastric cancer cell (MGC803) ferroptosis.GDF15 also plays an important role in erastin-induced ferroptosis by affecting the function of system Xc and regulating the expression of SLC7A11 (Chen et al., 2020a; Chen et al., 2020b). The gene discussed is GDF15; the disease is gastric cancer.
