In the original version of this article (1), there are errors in Figs. 2C and 4E and Supplementary Fig. S3. The authors inadvertently used the same image for p70S6K in SCC47 and SCC90 cells in Fig. 2C. The image of p-AKT-T308 in 93-VU-147T cells in Fig. 3A was duplicated in Supplementary Fig. S3A for p-AKT-T308 in 93-VU-147T cells. The same image was also used for E6 in the PDX-1 and PDX-3 models in Fig. 4E. In addition, a duplicated image was provided for p-AKT-S473 and p-AKT-T308 in SCC90 cells in Supplementary Fig. S3A. The correct original images have been provided, and the errors have been corrected in the latest online HTML and PDF versions of the article. The authors regret this error. Additional duplications were detected in Fig. 1D, 1F, and Fig. 3D, but the authors were unable to furnish the original data pertaining to those panels, which remain unchanged in the current versions. The editors have therefore addressed those issues in a separate Editor's Note (2).
