RESUMO
Following the publication of the above article, an interested reader drew to the authors' attention that the Transwell cell migration assay data shown in Fig. 4A appeared to be partly overlapping with data presented for experiments performed under different experimental conditions in Figs. 4D and E. The authors independently examined the figure and realized that inadvertent errors had been made during the assembly of Fig. 4; furthermore, owing to the time that has elapsed since this paper was published, the authors no longer had access to the original data. Accordingly, to further verify the conclusions reported in the study, the authors repeated these experiments, and the results obtained were found to be consistent with the original findings. The new version of Fig. 4 is shown below. The authors are grateful to the Editor of International Journal of Molecular Medicine for allowing them the opportunity to publish this Corrigendum, and apologize to the readership for any inconvenience caused.
