Retraction Notice to: hsa_circ_001653 Implicates in the Development of Pancreatic Ductal Adenocarcinoma by Regulating MicroRNA-377-MediatedHOXC6 Axis (Molecular Therapy - Nucleic Acids (2020) 20 (252–264), (S2162253120300081), (10.1016/j.omtn.2019.12.028))

Main text(Molecular Therapy: Nucleic Acids 20, 252–264; June, 2020) This article has been retracted at the request of the Editor-in-Chief. A reader contacted the Editor-in-Chief to report similarities between images in this article and an article previously published by unrelated authors in Cancer Cell International (Jiang et al., 2019, Cancer Cell Int. 19, 271, https://doi.org/10.1186/s12935-019-0977-9). These concerns were initially reported in a Pubpeer thread (https://pubpeer.com/publications/5F5842C32AABBFD0ED3E8C2814DD58). Image analysis performed by the editorial office confirmed the findings of image duplication in Figures 3G and 6E of the Molecular Therapy - Nucleic Acids article. This re use (and in part misrepresentation) of data without appropriate attribution represents a severe abuse of the scientific publishing system.
