RETRACTED ARTICLE: Long noncoding RNA LINC00657 enhances the malignancy of pancreatic ductal adenocarcinoma by acting as a competing endogenous RNA on microRNA-433 to increase PAK4 expression

Statement of Retraction

We, the Editors and Publisher of the journal Cell Cycle, have retracted the following article:

Shasha Bi, Yan Wang, Hu Feng & Qingchang Li (2020) Long noncoding RNA LINC00657 enhances the malignancy of pancreatic ductal adenocarcinoma by acting as a competing endogenous RNA on microRNA-433 to increase PAK4 expression, Cell Cycle, 19:7, 801-816, DOI: 10.1080/15384101.2020.1731645

Since publication, the authors informed us that ethical approval for the tumor xenograft experiments in mice reported in this article, had not been obtained from their institutional ethics committee. As this is a breach of research ethics requirements, the authors, Editor and Publisher have all agreed to retract the article to ensure the integrity of the scholarly record.

We have been informed in our decision-making by our policy on publishing ethics and integrity and the COPE guidelines on retractions.

The retracted article will remain online to maintain the scholarly record, but it will be digitally watermarked on each page as ‘Retracted’.
