Retraction to: Oncogene https://doi.org/10.1038/onc.2015.223, published online 15 June 2015
The Editor-in-Chief has retracted this article. After publication, concerns were raised regarding potential repetitive elements in the following figures:
Fig. 3B between the ZEB1-AS1 Huh7 and SMMC7721 images;
Fig. 4D within various images;
Fig. 4F between the SMMC7721 Control and ZEB1-AS1 images;
Fig. 5A within the ZEB1-AS1 image;
Fig. 5E within the Control image;
Fig. 6G between the siZEB1-AS1 Huh7 and SMMC7721 images.
The authors were unable to provide the original images used for the figures to address these concerns. Additionally, the study used the SMMC-7721 and L02 cell lines, which are known to be contaminated with HeLa. The Editor-in-Chief therefore no longer has confidence in the presented data.
