Subsequently to the publication of the above article, an interested reader drew to the authors' attention that, for the cell migration assay data shown in Fig. 4B, the data panels representing the 'miR‑NC inhibitor' and 'hypoxia' experiments appeared to contain overlapping sections, such that they may have been derived from the same original source. The authors have re‑examined their original data, and realize that Fig. 4B was assembled incorrectly. A corrected version of Fig. 4, showing in Fig. 4B the data from one of the repeated cell migration assay experiments, is shown on the next page. The authors confirm that these data continue to support the main conclusions presented in their paper, and are grateful to the Editor of Oncology Reports for allowing them this opportunity to publish this Corrigendum. They also apologize to the readership for any inconvenience caused. [Oncology Reports 34: 1943‑1952, 2015; DOI: 10.3892/or.2015.4195].
