<p>Exp Ther Med 13:<related-article id="RA1" related-article-type="retracted-article" vol="13" page="235" ext-link-type="doi" xlink:href="10.3892/etm.2016.3937">235&#x2013;241</related-article>, 2017; DOI: 10.3892/etm.2016.3937</p>
<p>Following the publication of this paper, it was drawn to the Editor&#x2019;s attention by a concerned reader that certain of the western blotting data shown in Fig. 5 on p. 240 were strikingly similar to data appearing in different form in another article written by different authors at different research institutes that had already been published in the journal <italic>Molecular Cancer</italic> prior to the submission of this paper to <italic>Experimental and Therapeutic Medicine</italic>. In view of the fact that the abovementioned data had already apparently been published previously, the Editor of <italic>Experimental and Therapeutic Medicine</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>
