Retraction: Celastrol inhibit the proliferation, invasion and migration of human cervical HeLa cancer cells through down-regulation of MMP-2 and MMP-9.

Abstract

Zhang J, Wang R, Cheng L, Xu H. Celastrol inhibit the proliferation, invasion and migration of human cervical HeLa cancer cells through down-regulation of MMP-2 and MMP-9. J Cell Mol Med. 2021;25:5335-5338. doi: 10.1111/jcmm.16488 The above article, published online on 4 May 2021 in Wiley Online Library (wileyonlinelibrary.com), has been retracted by agreement between the journal Editor-in-Chief, Stefan N. Constantinescu, and the Foundation for Cellular and Molecular Medicine/John Wiley & Sons Ltd. Following publication, concerns were raised by third parties that portions of Figure1 are identical to Figure1 presented in another article (1) from a different author group and covering a different research topic. Further investigation confirmed these concerns and revealed additional duplication in Figures1 and 2, overlapping with Figures1 and 3 in (1). The authors of both articles were approached for an explanation but the authors of this article did not respond. The authors of (1) were unable to provide any underlying data. The retraction has been agreed because of concerns regarding the integrity of the research presented given that the figures were duplicated. (1) Shi X, Luo X, Chen T, etal.
