ABCC9-repressed ferroptosis of BC cells is reversed by ZON. A, B The MDA-MB-231/Dox and MDA-MB-468/Dox cells were treated with ZON. A The mRNA expression of ABCC9 was detected by qPCR. B The protein expression of ABCC9 was analyzed by Western blot analysis. C The MDA-MB-231/Dox and MDA-MB-468/Dox cells were treated with ZON and ABCC9 overexpressing vectors. The cell viability was determined by CCK-8 assays. D–G The MDA-MB-231/Dox and MDA-MB-468/Dox cells were treated with erastin, ABCC9 overexpressing vectors, and ZON. The levels of GSH (D), MDA (E), lipid ROS (F), and iron (G) were detected. **P < 0.01
