The Molecular Cancer Research editors are publishing this note to alert readers to a concern about this article (1). An internal journal investigation determined that the same β-actin immunoblots were used to represent loading controls in Fig. 5B and C. In addition, an institutional investigation determined that the same microscopy image was used to represent untreated cells in different experimental conditions in Fig. 6B1 and B2. Original research records related to this concern were not available during the institutional investigation. Therefore, the institution was not able to determine the relation of the images to the experiments described.
