ACSL4 and breast cancer: Some previous studies have shown that some ferroptosis-related genes may be promising therapeutic targets for BC, such as ACSL4 (Acyl-CoA synthetase long chain family member 4, Gene ID: 2182), GPX4 (glutathione peroxidase-4, Gene ID: 2879), SLC7A11 (solute carrier family 7 member 11, Gene ID: 23,657), and SLC3A2 (solute carrier family 3 member 2, Gene ID: 6520)22,23.
