Retraction to: Cancer Gene Therapy https://doi.org/10.1038/s41417-021-00305-9, published online 26 February 2021

The Editor-in-Chief has retracted this article on request of the corresponding author. After publication, concerns were raised about partial overlap between Figure 7b NC Ki67 staining (SGC-7901 cell line) in this article, and Figure 6d Sh-NC c-myc staining in an article [1] published earlier by unrelated authors. The authors stated that the figures were obtained through a commercial lab hired to perform immunohistochemical tests and that some of the data were compromised making the conclusions of the article unreliable. The Editor-in-Chief has lost confidence in the data.

Author Huaxia Xie agrees to this retraction. The remaining authors have not responded to any correspondence from the editor or publisher about this retraction.
