<p>Oncol Lett 21: Article no. <related-article xmlns:xlink="http://www.w3.org/1999/xlink" related-article-type="corrected-article" vol="21" page="213" id="RA1" xlink:href="10.3892/ol.2021.12474" ext-link-type="doi">213</related-article>, 2021; DOI: 10.3892/ol.2021.12474</p>
<p>Subsequently to the publication of the above article, the authors have realized that, in <xref rid="f1-ol-0-0-12741" ref-type="fig">Fig. 1</xref>, the chemical structure of 4&#x2019;-hydroxychalcone was presented without one of its requisite double bonds.</p>
<p>A corrected version of <xref rid="f1-ol-0-0-12741" ref-type="fig">Fig. 1</xref>, including the correct chemical structure of 4&#x2019;-hydroxychalcone, is shown below. The authors are grateful to the Editor of <italic>Oncology Letters</italic> for granting them the opportunity to publish this corrigendum, and regret any inconvenience caused to the readership of the Journal.</p>

<caption><p>Experimental design and general <italic>in vivo</italic> observations. (A) The chemical structure of 4-HC. (B) Experimental design for the evaluation of the chemopreventive effect of 4-HC in male ApcMin mice. Mice were randomly allocated into groups for oral administration with 10 mg/kg/day 4-HC (n=12) or Veh control (n=11) from 8 to 20 weeks of age. Changes in (C) body weight over time and (D) HBG levels at 20 weeks for ApcMin mice orally treated with 4-HC (n=12) or Veh (n=11). Data are presented as the mean &#x00B1; SEM. &#x002A;P&#x003C;0.05, &#x002A;&#x002A;P&#x003C;0.01 vs. Veh. 4-HC, 4&#x2019;-hydroxychalcone; ApcMin, adenomatous polyposis coli multiple intestinal neoplasia mouse model; HGB, hemoglobin; Veh, vehicle.</p></caption>
