Abstract
Following the publication of the above article, an interested reader drew to the authors' attention that Figs. 3B and 4B contained western blot data (specifically, the MMP‑9 and Vimentin western blots in Figs. 3B and 4B, respectively) that were more similar than expected. Moreover, further strikingly similar data were also identified examining the western blot data within Fig. 4B and 4D, and also comparing the western blots in Figs. 1D, 3B, 4B and 4D with data featured in an article in the journal Oncotarget that was published subsequently to the above article, but which featured the first author (Pei Zhang) as an author in common. The authors were able to re‑examine their original data (which were also presented to the Editorial Office), and confirmed that the Vimentin data in Fig. 4B and the ZEB1 data in Fig. 4D were the same western bands as those featured for the MMP‑9 data in Fig. 3B and the Fibronectin data in Fig. 4B, respectively. These errors were made during the assembly of Fig. 4 (the data for MMP‑9 and Fibronectin were inadvertently duplicated in the figure). The corrected version of Fig. 4, now displaying the accurate experimental data for the Vimentin (Fig. 4B) and ZEB1 (Fig. 4D) blots in the CNE2Z and CNE2Z/DDP groups, is shown on the next page. Furthermore, regarding the issue of image duplication comparing between the above article published in 2014 and the one published in Oncotarget in 2015, the authors will contact the Oncotarget journal to handle the necessary corrections. The authors can confirm that the errors associated with this figure did not have any significant impact on either the results or the conclusions reported in this study, and all the authors agree with the publication of this Corrigendum. The authors are grateful to the Editor of International Journal of Molecular Medicine for allowing them the opportunity to publish this Corrigendum; furthermore, they apologize to the readership of the Journal for any inconvenience caused.
