A The analysis of expression levels of 24 ferroptosis-associated genes from GEO datasets (GEO58137). B The expression of iron metabolism-related proteins was detected by Western blot (n = 3). C Intracellular Fe2+ was detected after the knockdown of NCOA4 by the FerroOrange probe (1 μM, 30 min) (n = 3). Scale bars, 25 μm. D The expression of SA-β-Gal staining positive cells were ameliorated after knockdown of NCOA4 (n = 3). Scale bars, 100 μm. E The expression of P21, p-H2AX and IL-6 were ameliorated after knockdown of NCOA4 (n = 3). F Immunofluorescence staining of p-H2AX and 8-OhdG. Scale bars, 25 μm. Data are shown as Mean ± SD. *p < 0.05 vs. control group. #p < 0.05 vs. TBH group.
