SLC7A11 and cancer: We found that different cell death inhibitors, including the apoptosis inhibitor Z-VAD-FMK, the ferroptosis inhibitor ferrostatin-1, and the necroptosis inhibitor necrostatin-1s, showed no rescuing effect on H2O2-induced cell death in SLC7A11-high cancer cells, including 786-O cells with high overexpression of SLC7A11 and T98G cells (Supplementary Fig. 1d–h).
