Abstract
RETRACTION: Ma M., Zhao J., Wu Q., Xiao K., Li S., Zhu H., Liu C., Xie H., and Zuo C., “MiRNA‐545 Negatively Regulates the Oncogenic Activity of EMS1 in Gastric Cancer,” Cancer Medicine 7, no. 6 (2018): 2452–2462, 10.1002/cam4.1520.
The above article, published online on 07 May 2018 in Wiley Online Library (wileyonlinelibrary.com), has been retracted by agreement between the authors; the journal Editor‐in‐Chief, Stephen Tait; and John Wiley & Sons Ltd.
The retraction has been agreed due to the use of contaminated cell lines in this article. Both the cell lines used to demonstrate the regulatory role of miR‐545 in EMS1 expression (SGC‐7901 & BGC‐823) have been reported to be contaminated with HeLa [1, 2], as has cell line MGC‐803 [3, 4]. Thus, the editors consider the conclusions of this article to be invalid.
We did not find any evidence of misconduct by the authors.
