Abstract
Following the publication of the above article, an interested reader drew to the authors' attention that, for the cell migration assay experiments shown in Fig. 5 on p. 731, the 'TNF‑α' data panels in Fig. 5A and C appeared to be matching, where experiments performed under different conditions were intended to have been displayed. After having re‑examined their original data, the authors have realized that the data files were mislabelled, although they were able to retrieve the correct data for Fig. 5C (where the error occurred). The revised version of Fig. 5, containing the correct data for the TNF‑α experiment shown in Fig. 5C, is shown on the next page. Note that the error made during the assembly of this figure did not affect the overall conclusions reported in the paper. All the authors agree with the publication of this corrigendum, and are grateful to the Editor of International Journal of Molecular Medicine for allowing them the opportunity to publish this. They also apologize to the readership for any inconvenience caused. [International Journal of Molecular Medicine 34: 725‑732, 2014; DOI: 10.3892/ijmm.2014.1844].
