This article has been withdrawn by the authors. The corresponding author contacted the editorial office to report a concern raised about some figures in this article. An investigation by the Journal determined the following. Lanes 1 and 2 of the NF-κB EMSA shown in Fig. 1E are duplicates. The TAK1 KA panel in Fig. 1G has duplicated areas in which no signal was detected. The Bay11 + Dox and KU + Dox panels in Fig. 2A have overlapping regions. The KU + Dox panel in Fig. 2C was reused in Fig. 3F as Control. Because the original phosphorimager data for Fig. 1 (E and G) could not be found, the authors state that they do not have a definitive means of verifying the data in question in these two panels. The authors state that the issues in Figs. 2A and 3F were due to errors during figure preparation, and the correct cell images for Figs. 2A and 3F were found and submitted to the Journal. Given these errors, the authors state that the responsible course of action is to withdraw the article to maintain the high standards and rigor of the scientific literature from the authors and the Journal. However, the withdrawing authors assert that these errors do not change the underlying scientific findings of the article and that the results of this article are valid.
