RETRACTION: Exosomes Derived from miR-143-Overexpressing MSCs Inhibit Cell Migration and Invasion in Human Prostate Cancer by Downregulating TFF3 (Retraction of Vol 18, Pg 232, 2019)

Concerns regarding data integrity, which were based on a PubPeer thread showing similarities among western blots and an illustration in this article and articles published by unrelated authors, were raised by the National Science Library of the Chinese Academy of Sciences (https:// pubpeer.com/publications/2725A85FAC4C3C4037896AAC7C21E7). The authors provided original data in response to the editorial office???s investigation request. The original western blot images provided by the authors confirmed editing of the blots. The text and figures of the article show signs of template use, with marked similarities between this article and articles by unrelated authors, such as ???The Potential Therapeutic Role of Exosomal MicroRNA-520b Derived from Normal Fibroblasts in Pancreatic Cancer??? (Shi et al., 2020, Mol. Ther. Nucleic Acids 20, 373-384, https://doi.org/10.1016/j.omtn.2019.12.029) and ???Bone Marrow Mesenchymal Stem Cell-Derived Exosomal MicroRNA-126-3p Inhibits Pancreatic Cancer Development by Targeting ADAM9??? (Wu et al., 2019, Mol. Ther. Nucleic Acids 16, 229-245, https://doi.org/10.1016/j. omtn.2019.02.022). Given these issues, the editors believe that the findings of the manuscript cannot be relied upon. The authors disagree with the retraction.
