<p>Oncol Rep 44: <related-article xmlns:xlink="http://www.w3.org/1999/xlink" related-article-type="retracted-article" vol="44" page="1064" id="RA1" xlink:href="10.3892/or.2020.7684" ext-link-type="doi">1064&#x2013;1074</related-article>, 2020; DOI: 10.3892/or.2020.7684</p>
<p>Following the publication of the above paper, it was drawn to the Editor&#x0027;s attention by a concerned reader that the immunohistochemical images shown in Fig. 7E were strikingly similar to data that had already been published in different form in a previous article in the journal <italic>PLoS One</italic> written by different authors at different research institutes.</p>
<p>Owing to the fact that the abovementioned data had already apparently been published previously, the Editor of <italic>Oncology Reports</italic> has decided that this paper should be retracted from the Journal. 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>
