In Figure 6 in the paper titled “NADPH Oxidase-Induced NALP3 Inflammasome Activation Is Driven by Thioredoxin-Interacting Protein Which Contributes to Podocyte Injury in Hyperglycemia” [1], Figures 6(a) and 6(c) are completely the same pictures. This correction does not have any influence on the results and discussions of the study, which are correctly described in the text. In the published version of Gao et al., 2015, Figure 6(a) should be the representative Western blot graph of the expression of gp91phox in HG-exposed podocytes without or with TXNIP shRNA transfection. Below is the correct version of Figure 6.
