BA accelerated ferritinophagy in A549 and A549/DDP cells. A ROS levels were assessed by flow cytometry; B Changes in lipid peroxidation were detected; C The activity of Fe²⁺ was examined; D qRT-PCR was used to measure the relative mRNA levels of SLC7A11, and GPX4 in cells; E The relative abundances of SLC7A11, GPX4, SLC40A1, and transferrin were determined by western blot; F GSH and GSSH levels were calculated. *P < 0.05 vs Control; #P < 0.05 vs DDP
