Following the publication of the above article, the authors have realized that certain intended corrections were not carried over to the published version of the article. First, the description of the results of Figs. 5 and 6 did not match the figures; Edu and Transwell invasion assays were intended to have been excluded from the manuscript during the proofreading stage, although these data were presented in the description of the results for Figs. 5 and 6. Consequently, the text for the "circRNA_001275 promotes cell proliferation" subsection of the Results section towards the end of p. 153 should have read as follows: "MTT assay was used to detect the effects of circRNA_001275 on cell proliferation. The results showed that cell viability was significantly increased in the circRNA_001275 OE group, and significantly decreased in the si circRNA_001275 group (both P<0.05, Fig. 5A and B), compared with the corresponding control groups." Furthermore, the text in the subsequent subsection ("circRNA_001275 inhibits cell apoptosis") should have read as follows: "Hoechst 33258 staining was used to detect the effects of circRNA_001275 on apoptosis. The apoptosis rate was significantly decreased in the circRNA_001275 OE group, and significantly increased in the si circRNA_001275 group (both P<0.05; Fig. 6), compared with the corresponding control group.

Figure 5 circRNA_001275 promotes cell proliferation (n=3). *P<0.05, **P<0.01 vs. pcDNA3.1 or si-NC. circRNA, circular RNA; DDP, cisplatin; NC, negative control; OD, optical density; OE, overexpression vector; si, small interfering RNA.

Figure 6 circRNA_001275 inhibits cell apoptosis (n=3). (A) Hoechst 33258 staining assay. (B) Numbers of positive cells (n=3). *P<0.05, **P<0.01 vs. pcDNA3.1 or si-NC. circRNA, circular RNA; DDP, cisplatin; NC, negative control; OE, overexpression vector; si, small interfering RNA.

Secondly, Fig. 5B was omitted from Fig. 5 in the published article; and thirdly, a higher-resolution version of Fig. 6 was submitted during the revision stages, although the version of this figure that was deemed to have been too low in quality was the one that appeared in the final proofs. The corrected / updated versions of Figs. 5 and 6 are shown opposite.

The Editor of International Journal of Oncology regrets that certain of these errors were introduced into the article during the production stages, and apologizes both to the authors and to the readership.
