Erratum: Downregulation of p53-inducible microRNAs 192, 194, and 215 Impairs the p53/MDM2 Autoregulatory Loop in Multiple Myeloma Development (Cancer Cell (2010) 18(4) (367–381) (S1535610810003429) (10.1016/j.ccr.2010.09.005))

(Cancer Cell 18, 367–381; October 19, 2010) During figure preparation for the original article, the image of the western blot showing MDM2 protein expression upon miR-194, 192, 215, and scrambled sequence (Scr) treatments in the MM1s cell line was mistakenly replaced in Figure 4A with the image of the western blot showing MDM2 in NCI-H929 cells in the same figure panel. The correct corresponding image of the western blot showing MDM2 protein expression in MM1s is shown below in the corrected Figure 4A. In addition, because multiple normalizations of the same set of samples were performed due to the use of phospho-antibodies, the authors inadvertently duplicated the Gadph image of MM1s in the total Akt image of NCI-H929 in the same panel. The results were not affected by this duplication. The corresponding total Akt and Gapdh images used for pAkt normalization for both RPMI-8226 and MM1s are now included in the corrected Figure 7A, shown below. The authors apologize for these errors and any confusion that they may have caused.
