The journal was informed that the p65 and myc (p65) blots in Fig. 1A,B are identical to those shown in fig. 3A,B of another paper by the same authors in BMC Genomics (2010) 11, 22 (doi:10.1186/1471-2164-11-22). The authors explained that the data in the two figures validate the specificity of antibodies generated against different acetylated lysines of p65 and originate from the same experiment, meaning that use of the same controls is justified. Although the BMC Genomics paper was referenced and discussed, the authors should have stated in the legend for Fig. 1 that these control blots were reproduced from their earlier paper. The corrected and original legends are shown below and the online full-text and PDF versions of the paper have been updated.
The authors apologise to readers for this omission, which does not impact the results or conclusions of the paper.
