Abstract
Following the publication of the above article, the authors subsequently realized that, during the process of collating the raw data, Fig. 1 [the immunohistochemical (IHC) results for stage IV colorectal cancer (CRC)], Fig. 2A (the control β‑actin blots) and Fig. 5C and D (both the images selected for the clone formation assays, and the histograms showing the quantification of the data) were inadvertently assembled incorrectly. These errors arose as a consequence of the affected files having been named similarly to those of the correct panels. The revised versions of Figs. 1, 2 and 5, now featuring the correct IHC data for stage IV CRC in Fig. 1, the correct control western blots in Fig. 2 and the correct colony formation assay data (and quantification thereof) in Fig. 5, are shown on the next three pages. Note that the correction of these figures does not affect the key findings of the study (either the existing published results or the conclusions reached from the results). The authors thank the Editor of International Journal of Oncology for granting them the opportunity to publish this corrigendum. All the authors agree with the publication of this corrigendum; furthermore, they apologize to the readership of the journal for any inconvenience caused.
