Following the publication of the above article, an interested reader drew to the authors' attention that the RT‑PCR data panels shown in Fig. 3C, showing the effects of PBIT and PBI‑Se treatment on endogenous IL‑8 mRNA expression levels in CaCo₂ cells, contained issues. Specifically, on p. 956, a pair of the β‑actin bands in the bottom panel of Fig. 3C were strikingly similar to those featured in the upper panel. Upon examining their original data, the authors realized that the bottom β‑actin panel in Fig. 3C had inadvertently been assembled incorrectly. Moreover, a typo was also identified in the Fig. 3C legend. The revised version of Fig. 3, showing the correct data for the β‑actin bands in the bottom panel in Fig. 3C, and now accurately displaying the correct images for the IL‑8 mRNA and β‑actin expression experiments, is shown on the next page. Additionally, the typo in the Fig. 3C legend has been corrected to read as follows: ‘PBI‑Se (1‑4 µM) and PBIT (30‑60 µM) treatment reduced endogenous IL‑8 mRNA expression in CaCo₂ cells’. Note that the revisions made to this figure do not affect the overall results or the conclusions reported in the paper. The authors are grateful to the Editor of Oncology Reports for granting them the opportunity to publish this corrigendum, and all the authors agree with its publication; furthermore, they apologize to the readership of the journal for any inconvenience caused.
