Following the publication of the above paper, the
authors requested that a corrigendum be published for Fig. 5 on
account of the fact that the gel bands selected for Nrf2 and GAPDH
(in Fig. 5A) had been wrongly used. Upon performing an independent
analysis of the data in this paper in the Editorial Office, it also
came to light that the protein band for PERK in Fig. 3A for the 5
μM salinomycin experiment with the PC-3 cell line was strikingly
similar to the band shown for the 0 μM salinomycin experiment for
the DU145 cell line. Furthermore, in Fig. 4A, the protein bands for
HO-1 for the 2 and 5 μM salinomycin experiments for the PC-3 and
DU145 cell lines also appeared to be broadly similar.
Upon asking the authors to provide an explanation for
these additional figures, they were able to show how Figs. 3 and 5
had been erroneously assembled, but were not able to retrieve the
complete uncropped exposure files for the data in Fig. 4A owing to
data archiving limitations at the time. Although alternative data
were offered for the corrigendum for Fig. 4, following this
internal enquiry the Editor of Experimental and Therapeutic
Medicine has decided that this paper should be retracted due to
an overall lack of confidence in the presentation of Fig. 4 as it
was originally shown. After contacting the authors, they accepted
the decision to retract the paper. The Editor apologizes to the
readership of the Journal for any inconvenience caused.
