<p>Mol Med Rep 17: <related-article xmlns:xlink="http://www.w3.org/1999/xlink" related-article-type="corrected-article" vol="17" page="7545" id="RA1" xlink:href="10.3892/mmr.2018.8828" ext-link-type="doi">7545&#x2013;7552</related-article>, 2018; DOI: 10.3892/mmr.2018.8828</p>
<p>Following the publication of the above article, a concerned author drew to the authors&#x2019; attention that, in <xref rid="f1-mmr-33-6-13890" ref-type="fig">Fig. 1B</xref> on p. 7548, the first two lanes for the lower set of &#x03B2;-actin western blots were unexpectedly similar to the data shown for the ATM protein blots in the third and fourth lanes in the same figure part. In addition, the upper set of &#x03B2;-actin western blots featured in <xref rid="f1-mmr-33-6-13890" ref-type="fig">Fig. 1B</xref> were also strikingly similar to the blots shown for the Bax protein in <xref rid="f2-mmr-33-6-13890" ref-type="fig">Fig. 2</xref> on p. 6549. Moreover, an independent analysis of the data in this paper undertaken by the Editorial Office also revealed that the TAp73 and GRAMD protein blots shown in <xref rid="f2-mmr-33-6-13890" ref-type="fig">Fig. 2</xref> were very similar.</p>
<p>After having re-assessed these figures, the authors have submitted corrected versions of <xref rid="f1-mmr-33-6-13890" ref-type="fig">Figs. 1</xref> and <xref rid="f2-mmr-33-6-13890" ref-type="fig">2</xref>, as shown on the next page, featuring revised data for the upper and lower sets of &#x03B2;-actin blots in <xref rid="f1-mmr-33-6-13890" ref-type="fig">Fig. 1</xref>, and the TAp73 blots and certain of the &#x03B2;-actin blots in <xref rid="f2-mmr-33-6-13890" ref-type="fig">Fig. 2</xref>. Note that these errors did not affect the results or the main conclusions reported in the study. All the authors approve of the publication of this corrigendum, and are grateful to the Editor of <italic>Molecular Medicine Reports</italic> for allowing them the opportunity to publish this. The authors regret their oversight in allowing these errors to be included in the paper, and apologize to the readership for any inconvenience caused.</p>
