The Molecular Cancer Research editors are publishing this note to alert readers to concerns about this article (1). An institutional investigation suggested that the images used in this article above the first and fourth bars in Fig. 5F to represent DU 145 cells appear to have been reused in a Molecular Cancer article (2) above the fifth and sixth bars, respectively, in Fig. 4D to represent PC-3 cells. Original research records related to these concerns were not available during the institutional investigation; therefore, the institution was not able to determine the relation of the images to the experiments described in this article (1). Moreover, an internal journal investigation could not dismiss the possibility that the images in question were reused as described.

Because a satisfactorily corrected figure could not be provided, the editors are publishing this note to alert readers to these concerns.
