Erastin exerts cytotoxic, but not cytostatic, effects to cultured colorectal cancer cells. Colorectal cancer cells (HT-29, DLD-1 and Caco-2 lines) or NCM460 colon epithelial cells were treated with vehicle control (0.1% DMSO, “Ctrl”) or indicated concentrations of erastin for applied time, cell survival was tested by MTT assay (A and E) and colony formation assay (C); The percentage of trypan blue positive (“dead” cells) was recorded (B); Cell proliferation was tested by BrdU incorporation assay (D and F). For each assay, n = 5. The data presented were mean ± SD. Experiments were repeated three times with similar results obtained. * p < 0.05 vs. group of “Ctrl”.

Baicalein suppresses erastin-induced GPX4 degradation. (A) PANC1 and BxPc3 cells were treated with erastin (20 μM) in the absence or presence of baicalein (10 μM) for 24 h. The indicated protein levels were assayed using western blot. (B) In parallel, the relative intensity of the western blot band of GPX4 was quantified using ImageJ densitometry software (n = 3, *, p < 0.05).

FANCD2 suppresses erastin-induced ferroptosis in BMSCs. (A) FANCD2+/+ and FANCD2 −/− BMSCs were treated with erastin (0.625–2.5 μM) for 24 h and cell viability was assayed (n = 3, *P < 0.05). (B) Interference contrast images of FANCD2+/+ and FANCD2 −/− BMSCs with or without erastin (1.25 μM) treatment for 24 h (C) FANCD2+/+ and FANCD2 −/− BMSCs were treated with erastin (1.25 μM) in the absence or presence of ferroptosis inhibitor (ferrostatin-1, 500 nM; liprostatin-1, 200 nM; β-mercaptoethanol, 50 μM; N-acetylcysteine, 100 mM) or autophagy inhibitor (chloroquine, 10 μM; 3-methyladenine, 5 mM) for 24 h. Cell viability was assayed (n = 3, *P < 0.05 versus erastin treatment group). (D) Western blot analysis of LC3-I and LC3-II expression in FANCD2+/+ and FANCD2 −/− BMSCs following erastin (1.25 μM) treatment for 24 h. (E) In parallel, the LC3-II/I ratio quantified by densitometry analysis of bands.

Erastin选择性致死致癌的Ras突变体细胞系，并触发独特的fe依赖性的称为ferroptosis的非凋亡细胞死亡。[1] [2] Erastin直接结合VDAC2并且使得通过NADH-依赖方式产生ROS导致线粒体损害，在一些表达激活突变的肿瘤细胞中，通过RAS-RAF-MEK途径诱导细胞死亡。[3] 此外，erastin通过诱导ROS介导的CID（胱天蛋白酶非依赖性细胞死亡），强烈增强了野生型EGFR细胞的作用。[4] |
