Following the publication of this paper, it was drawn to the Editor's attention by a concerned reader that fluorescence microscopy data shown in Fig. 2C were strikingly similar to data appearing in different form in Fig. 3G in a previously published paper by different authors at different research institutes [Jieensinue S, Zhu H, Li G, Dong K, Liang M and Li Y: Tanshinone IIA reduces SW837 colorectal cancer cell viability via the promotion of mitochondrial fission by activating JNK‑Mff signaling pathways. BMC Cell Biology 19: 21, 2018]. Owing to the fact that the contentious data in the above article had already been published prior to its submission to International Journal of Molecular Medicine, the Editor has decided that this paper should be retracted from the Journal. After having been in contact with the authors, they accepted the decision to retract the paper. The Editor apologizes to the readership for any inconvenience caused. [International Journal of Molecular Medicine 45: 151‑161, 2020; DOI: 10.3892/ijmm.2019.4398].
