<p>Oncol Rep 44: <related-article xmlns:xlink="http://www.w3.org/1999/xlink" related-article-type="retracted-article" vol="44" page="313" id="RA1" xlink:href="10.3892/or.2020.7597" ext-link-type="doi">313&#x2013;324</related-article>, 2020; DOI: 10.3892/or.2020.7597</p>
<p>Following the publication of the above article and a corrigendum (doi: 10.3892/or.2023.8593) that was published 3 years ago to resolve the issue of duplicated data that had been noted comparing Figs. 1B and C, and 3B and C, respectively, a concerned reader has contacted the Editorial Office to draw our attention to the fact that a series of potential duplications of western blot data had also been noted comparing Fig. 4 with Fig. 5B.</p>
<p>Given the discovery of these additional errors that were made in terms of the assembly of two other figures in the above paper, the Editor of <italic>Oncology Reports</italic> has decided that this article should now be retracted from the Journal on account of a lack of confidence in the originally presented data. The authors were asked for an explanation to account for these concerns, but the Editorial Office did not receive a reply. The Editor apologizes to the readership for any inconvenience caused.</p>
