During the preparation of the figures in the above article, the authors inadvertently selected images for the shCTL experiments portrayed in Fig. 5I and J (for the MGC803 and SGC7901 cell lines, respectively) that were generated from the same original data source. A corrected version of Fig. 5 is shown opposite, showing the correct data for the shCTL experiment performed in SGC7901 cells (Fig. 5J). This error did not affect the major conclusions reported in the paper. All the authors have agreed to this Corrigendum. The authors regret this error, and apologize for any confusion that it may have caused. [the original article was published in Oncol Rep 40: 2325‑2333, 2018; DOI: 10.3892/or.2018.6614].
