Main text (Molecular Therapy: Oncolytics 11 , 14–19; December 2018) Molecular Therapy Oncology is retracting this article at the request of the editor-in-chief. An editor from another journal communicated concerns to the editorial office. Their investigation drew attention to similarities between the figures in this article and in a retracted article by unrelated authors in FEBS Letters (Xu et al., 2013, 3166–74, https://doi.org/10.1016/j.febslet.2013.05.069 ). Image analysis performed by the editorial office revealed evidence of image duplication involving Figures 3C, 4A, and 6B of this Molecular Therapy Oncology article. This reuse of data without appropriate attribution represents a severe abuse of the scientific publishing system. The authors did not respond to the original notice of retraction.
