In view of the fact that the abovementioned data had already apparently been published prior to its submission to , the Editor has decided that this paper should be retracted from the Journal. The authors were asked for an explanation to account for these concerns, but the Editorial Office did not receive a satisfactory reply. The Editor apologizes to the readership for any inconvenience caused. [International Journal of Molecular Medicine 43: 1149‑1156, 2019; DOI: 10.3892/ijmm.2018.4044].
