The editors became aware of several image duplications within the paper linked above, published in June of 2019. Duplications within Figure 2B and Figure 6C have been identified, which cast doubt upon the validity and reliability of the study’s findings. Specifically, in Figure 2B, sections within the oe-NC and sh-NC panels were duplicated. In Figure 6C, duplications were found within the 5-aza-dc and oe-PTEN panels.
Both the authors and their affiliated institution were contacted in an effort to obtain an explanation for these discrepancies. Despite multiple attempts, we have not received any response from either party.
In light of these unresolved concerns and in adherence to the Committee on Publication Ethics (COPE) guidelines, the editors have made the decision to retract the paper.
