Following the publication of the above article, an interested reader drew to the authors' attention that the 'NB‑4' and 'NB‑2' panels for the invasion and migration assays shown in Fig. 3B and C on p. 113 appeared to contain overlapping data, such that the data may have been derived from the same original source, even though the panels were intending to have shown results obtained under different experimental conditions. The authors have re‑examined their raw data and realized that these data were inadvertently mixed up when Fig. 3B and C were assembled. A corrected version of Fig. 3, showing the data as they should have appeared for the 'NB‑4' and 'NB‑2' invasion and migration assay experiments in Fig. 3B and C, is shown on the next page. The authors sincerely apologize for the errors that were introduced into Fig. 3 of the published article, and thank the Editor of Oncology Reports for allowing them the opportunity to publish a Corrigendum. All the authors agree to the publication of the authors, and they apologize to the readership for any inconvenience caused. [Oncology Reports 29: 109‑116, 2013; DOI: 10.3892/or.2012.2069].
