There was a mistake in Figure 2 as published. The image for the DFO group in Figure 2C was mistakenly replaced with the control group’s image, resulting in partial overlap between Figure 1C and Figure 2C. Additionally, to prevent misinterpretation of the ALI (25 μM) groups in Figures 1C and Figure 2C, we have used new images for the ALI group in Figure 2C. Finally, the housekeeping protein β-actin in Figure 2E was inadvertently duplicated from Figure 5C, and we have corrected this error. The corrected Figure 2 appears below.
FIGURE 2.
ALI-induced cytotoxicity could be alleviated by iron chelator DFO. (A) Cell viability of HK-2 cells was detected using CCK-8 assay. (B) Intracellular Fe2+ levels in HK-2 cells treated by ALI and DFO. (C,D) Intracellular GSH content in HK-2 (X200). (E,F) The protein levels of 4-HNE were measured by Western blot. * p < 0.05, ** p < 0.01, *** p < 0.001, **** p < 0.0001 vs. the control group; # p < 0.05, ## p < 0.01, ### p < 0.001, #### p < 0.0001 vs. the ALI group.
