Abstract

Statement of Retraction We, the Editors and Publisher of the Cell Cycle journal, have retracted the following article: Shen, Zhengchao, Jian Wang, Kunbin Ke, Rong Chen, Aixue Zuo, Rongping Zhang, Weiping Wan, et al. Polyphyllin I, a Lethal Partner of Palbociclib, Suppresses Non-Small Cell Lung Cancer through Activation of P21/CDK2/Rb Pathway in Vitro and in Vivo. Cell Cycle. 2021;20(23):2494–2506. doi:10.1080/15384101.2021.1991121 Since publication, concerns have been raised about the integrity of the data in the article. The authors kindly provided their data as part of the investigation, however, we reviewed the data and confirmed that the concerns remained. As verifying the validity of published work is core to the integrity of the scholarly record, we are therefore retracting the article. The authors do not agree with the retraction. We have been informed in our decision-making by our editorial policies and the COPE guidelines. The retracted article will remain online to maintain the scholarly record, but it will be digitally watermarked on each page as ‘Retracted’.
