Antitumor activity of CNSI-Fe to CT26.WT cells in vitro. a Cell proliferation. b Intracellular Fe contents. c Mitochondrial membrane potentials. d Hydroxyl radical generations. e GPX4 levels. f ACSL4 levels. g TEM image of control group. h TEM image of the cell exposed to CNSI-Fe. ASS means autolysosome, M means mitochondria, and the red arrows indicate the xenobiotic particles. * p < 0.05, ** p < 0.01, *** p < 0.001 comparing to the control group
