Figure Lengend Snippet: The results of the cellular validation experiments. (A,G) LCN2 expression levels in BEAS-2B cells after co-culture with nano-Fe 2 O 3 for 24 hours. (B,H,I) Expression profiles of GPX4 and FTH1 in BEAS-2B cells following co-culture with nano-Fe 2 O 3 for 24 hours. (E,K) Immunofluorescence validation of GPX4 expression in BEAS-2B cells after co-culture with nano-Fe 2 O 3 for 24 hours. (F,L) Immunofluorescence validation of FTH1 expression in BEAS-2B cells after co-culture with nano-Fe 2 O 3 for 24 hours. (C) Changes in ROS levels in BEAS-2B cells following co-culture with nano-Fe 2 O 3 for 24 hours. (D) Mitochondrial alterations in BEAS-2B cells observed via electron microscopy after co-culture with nano-Fe 2 O 3 for 24 hours. In the treated group, mitochondria (red arrows) exhibited discernible alterations such as a reduction in cristae and swelling (green arrows), compared to those in untreated cells. (J) Alterations in intracellular Fe 3+ levels in BEAS-2B cells following co-culture with nano- Fe 2 O 3 for 24 hours. *, P<0.05; **, P<0.01. BEAS-2B, bronchial epithelial cells, adenovirus 12-SV40 2B immortalized; DAPI, 4’,6-diamidino-2-phenylindole; ROS, reactive oxygen species.
