The Editor and Publisher of OncoTargets and Therapy wish to retract the published article. Concerns were raised regarding the alleged duplication of images in Figure 3C. Specifically,

• Figure 3C, DMSO appears to have been duplicated with the same image for Figure 3C, ACNU.

The authors responded to our queries and explained that the image duplication in Figure 3 was due to image misplacement during preparation of the figure. The authors were asked to provide original data that would adequately verify the reported findings, however the authors explained that some of the original data had been lost and the remaining data was not satisfactory. The Editor determined that the reported findings were unreliable and requested to retract the article. The authors agreed with this decision.

We have been informed in our decision-making by our policy on publishing ethics and integrity and the COPE guidelines on retractions.

The retracted article will remain online to maintain the scholarly record, but it will be digitally watermarked on each page as “Retracted”.
