The present study investigated whether Sal attenuates myocardial I/R injury by modulating ubiquitin‑specific protease 11 (USP11)‑mediated deubiquitination and stabilization of peroxiredoxin 2 (PRDX2). An <i>in vitro</i> H9c2 anoxia/reoxygenation (A/R) model and an <i>in vivo</i> rat I/R model were established. Sal significantly improved the viability of A/R‑injured H9c2 cells and reduced reactive oxygen species accumulation, ferrous iron overload and lipid peroxidation. Mechanistically, Sal upregulated the expression levels of USP11, glutathione peroxidase 4 and PRDX2 while suppressing prostaglandin‑endoperoxide synthase 2; notably, these effects were attenuated by USP11 silencing. Molecular docking and cellular thermal shift assay analyses suggested that USP11 may represent a potential molecular target involved in Sal‑mediated cardioprotection, thereby increasing its thermal stability and strengthening the USP11‑PRDX2 interaction. This may facilitate the USP11‑mediated stabilization of PRDX2, prolonging its half‑life and preserving cellular redox homeostasis. <i>In vivo</i> experiments further demonstrated that Sal pretreatment markedly reduced myocardial infarct size and improved cardiac contractile function, which was associated with the concurrent upregulation of the USP11‑PRDX2 axis.

First, in the Materials and methods section, the single‑cell RNA sequencing (RNA‑seq) source did not appear to match the presented groups for the scRNA‑seq data that were obtained from the GSE116222 dataset, specifically using 'three human UC samples', where three distinct groups, namely the 'Normal', 'Non‑inflamed' and 'Inflamed' groups, were shown in various of the figures (for example, Fig. 1D and Fig. 6K). Secondly, the description of the Weighted Gene Co‑expression Network Analysis (WGCNA) in the Materials and methods section did not tally with the findings reported in the Results section. It was stated in the '<i>Construction of co‑expression network</i>' subsection of the Methods that WGCNA was performed 'based on the GSE116222 dataset, specifically exploring the association between FXR and CD133 in intestinal cells'; however, all the WGCNA results shown (in Figs. 4D and 5A) were based on the bulk transcriptome dataset GSE87466, not on single‑cell data; no WGCNA output from GSE116222 was presented in the paper. Thirdly, some confusion between human and mouse data appeared in the reporting of the experiments in Fig. 1E. The figure part showed macroscopic photographs of whole large intestines and spleens labeled 'Control' and 'UC groups', and these images must have been derived from the DSS‑treated mouse model. The figure legend did not specify that these are mouse data, and the labeling of the 'UC group' was misleading. Finally, a typographical error in the reporting of the human control group sex distribution was contained in the '<i>Human sample collection and processing</i>' subsection: 'the control group consisted of 8 men and 2 men' was presumably intended to have read as '8 men and 2 women'. The authors have considered these points, and acknowledge that clarifications of all of them are necessary in the published paper; therefore, the following changes and edits to the text are required (all highlighted in <b>bold</b>). First, in the 'Materials and methods' section, in the '<i>Single‑cell RNA sequencing (scRNA‑seq)</i>' subsection, the text which read as 'scRNA‑seq data from three human UC samples were downloaded from the Gene Expression Omnibus (GEO) database...' has now been changed to 'scRNA‑seq data from <b>9 samples (3 healthy, 3 non‑inflamed, and 3 UC)</b> were downloaded from the Gene Expression Omnibus (GEO) database...'

In addition, the reader also observed that one of the antibodies the authors had used in their study was apparently selected inappropriately: The antibody (cat. no. ab51243) that the authors reported to have used is specific for the protein known as p16‑ARC (or ARPC5), not the apoptosis‑associated protein p16‑INK4a, as was intended. After re‑examining their original data, the authors have realized that the data in Fig. 1B were assembled incorrectly. A revised version of Fig. 1 is shown on the next page, now featuring data for all the panels in Fig. 1B from one of the repeated sets of experiments. Concerning the potential selection of an inappropriate antibody to probe for p16 protein, the authors expressed their regret that they had not retained their original receipt for the purchase of this antibody, and were not in a position to prove whether or not the antibody had been chosen legitimately for the affected experiments; however, an increased abundance of p16‑INK4a was used as an indicator of cellular senescence in combination with the abundance of p21 and the fraction of cells that contained a SA‑β‑gal signal. In view of this, the authors considered that removing the p16 data from the paper would not compromise the conclusions drawn in this study. After considering this appeal, the Editor has approved the authors' request that the p16 data be omitted from this study. Therefore, all references to 'p16' in this study (as were featured in the Abstract, and the Materials and methods, Results and Discussion sections) should be considered to be eliminated from this paper; the revised version of Fig. 1 that has been provided to take account of the new data in Fig. 1B also no longer includes the p16 data, and a new version of Fig. 3 has also been provided (on the third page of this corrigendum), again with the p16 data excluded.
