Retraction: Combining PARP-1 Inhibition and Radiation in Ewing Sarcoma Results in Lethal DNA Damage

This article (1) has been retracted at the request of the editors. In Fig. 4B, a portion of the immunofluorescence image for SK-N-MC cells, treated with DMSO, appears identical to HT1080 cells treated with Olaparib. An internal review of western blot analysis in Fig. 1B also revealed a duplication in which the same image was used to represent SK-LMS-1 cells at 24 hours and SK-N-MC cells at 0 hour. The western blot duplication was noted after applying adaptive histogram equalization to the figure using image analysis software.
