However, the various types of ferroptotic cancer cells described above may activate or inhibit different immune cells; thus, the proportion of different ferroptosis-related molecules in cancer cells, such as glutathione peroxidase 4 (GPX4), long-chain family member 4 (ACSL4), and solute carrier family 7 member 11 (SLC7A11), is a double-edged sword 3, 5, 17. The gene discussed is SLC17A1; the disease is cancer.
