[Corrigendum] S100A9 promotes the proliferation and invasion of HepG2 hepatocellular carcinoma cells via the activation of the MAPK signaling pathway.

Subsequently to the publication of the above article, an interested reader drew to the authors' attention that two pairs of data panels in Fig. 7D on p. 1008, showing the results from Transwell invasion assay experiments, contained overlapping sections such that these panels were likely to have been derived from the same original sources where they were intended to show the results from differently performed experiments. After having consulted their original data, the authors were able to identify that two of the data panels in Fig. 7D were inadvertently selected incorrectly; specifically, the 'GST+SB203580' and 'GST‑hS100A9+PD98059' panels in this figure. The revised version of Fig. 7, showing the correct data panels for the 'GST+SB203580' and 'GST‑hS100A9+PD98059' panels in Fig. 7D, is shown on the next page. The authors confirm that the errors made during the assembly of Fig. 7 did not grossly affect the major conclusions presented in this paper, and are grateful to the Editor of International Journal of Oncology for allowing them this opportunity to publish a Corrigendum. They also apologize to the readership for any inconvenience caused. [International Journal of Oncology 42: 1001-1010, 2013; DOI: 10.3892/ijo.2013.1796].
