Abstract
Following the publication of the above article, an interested reader drew to the authors' attention that the 'Control' and 'miR‑218 / BMI1' data panels for the Transwell invasion assay experiments shown in Figs. 4D and 5D on p. 100 and 101 respectively contained apparently overlapping data, albeit presented in different orientations, such that these data would have been derived from the same original source, even though they were intended to have shown the results from different experiments. On re‑examining their original data, the authors realized that they had inadvertently assembled the data from the Transwell assay experiments incorrectly in Figs. 2, 4 and 5. The authors elected to repeat these Transwell assay experiments in view of the errors made in assembling these figures, and the revised versions of Figs. 2, 4 and 5 (specificially, containing the replacement Transwell assay data in Figs. 2F, 4D and 5D) are shown on the next three pages. Note that the errors made in assembling these figures 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 granting them the opportunity to publish this. Furthermore, they apologize to the readership for any inconvenience caused. [International Journal of Molecular Medicine 36: 93‑102, 2015; DOI: 10.3892/ijmm.2015.2216].
