Article Title: Distinct TP53 Mutation Types Exhibit Increased Sensitivity to Ferroptosis Independently of Changes in Iron Regulatory Protein Activity
doi: 10.3390/ijms21186751
Figure Lengend Snippet: Erastin treatment differentially affects TFRC and ferritin heavy chain 1 (FTH1) protein expression in cells expressing distinct TP53 mutation types. Representative images and quantification of Western blots examining the expression of ( A , B ) transferrin receptor 1 (TFRC) and ( C , D ) ferritin heavy chain 1 (FTH1) in TP53 null H1299 cells (H1299) or H1299 cells transfected with wild-type (WT) TP53, or the indicated TP53 mutant following treatment with DMSO (control) or 10 µM erastin for 24 h ( n = 3–4 per cell type and treatment). Relative expression was normalized using glyceraldehyde 3-phosphate dehydrogenase (GAPDH) as a loading control. * Denotes statistical differences from respective control, p < 0.05. Error bars indicate SEM.
