Retraction Note to: Cell Death and Disease 10.1038/s41419-021-04158-w, published online 23 September 2021
The Editors-in-Chief have retracted this article at the author’s request. After the publication of the article, the authors realized that errors were made during the storage, naming, selection, and uploading of images for Figs. 3J, 3F, 7E, and 8H. Further investigation by the Publisher found that the following image overlaps. Therefore, the Editors-in-Chief have no longer confidence in the data presented in the article.
- Partial image overlap between Figs. 3H (MKN-45, shRNA2) and 3J (MKN-45, shRNA1)
- Partial image overlap between Figs. 7E (MKN-45, OE-NC) and 7G (MKN-45, OE-PPM1E+mimics-NC)
- Partial image overlap between Figs. 7E (MKN-45, OE-PPM1E) and 7E (MKN-45, OE-PPM1E+mimics-NC)
- Image overlap between Figs. 8H (MKN-45, shNC+OE-NC) and 8H (MKN-45, shRNA2+OE-PPM1E)
Yinhao Chen, Chen Qian, Shaoqing Ju, Xinliang Gu, and Shou Ma agree to this retraction. Authors, Lei Shen and Shaoqing Ju have not responded to any correspondence from the editor/publisher about this retraction.
