In the article entitled, “Cellular Prion Protein Mediates Pancreatic Cancer Cell Survival and Invasion through Association with and Enhanced Signaling of Notch1” (Volume 186, pages 2945–2956 of the November 2016 issue of The American Journal of Pathology; http://dx.doi.org/10.1016/j.ajpath.2016.07.010), Figure 1B and Figure 6B contained errors regarding unintentional duplication of mislabeled blots. These duplications were brought to the attention of the Editorial office by a concerned reader, and the authors have provided the original blots from which the figures were intended to be generated. This error was found to be accidental and the corrected figure panels appear below (Figure 1B on the left, Figure 6B on the right). The original legends to the figures were not affected.
