Abstract
Following the publication of the above article, a pair of interested readers drew to the Editor's attention that certain of the western blotting data featured in Figs. 1A and 3A were strikingly similar to data that had appeared in a pair of articles published previously by the same research group. Subsequently, an independent investigation of the data in this paper on the part of the Editorial Office revealed that a pair of the panels showing the results of cell invasion assays in Fig. 4A on p. 405 for the MCF7‑WT cells appeared to contain overlapping sections, such that data which were intended to show results from entirely different microscopic fields had apparently been derived from partly the same original field of view. Upon investigating these matters with the authors, they were able to repeat the experiments concerned (in the case of Figs. 1 and 3). The revised versions of Figs. 1, 3 and 4, now featuring the replacement data for Figs. 1A and 3A and the two completely differentiated microscopic fields of view for Fig. 4, are shown on the next two pages. The authors regret that certain of the data featured in Figs. 1 and 3 of this article were erronoeusly re‑used from a pair of their previous publications, and thank the Editor of International Journal of Oncology for granting them the opportunity to publish this corrigendum. All the authors agree with the publication of this corrigendum; furthermore, they apologize to the readership of the journal for any inconvenience caused.
