Retraction notice

The authors would like to retract the article "MyoD-dependent regulation of NF-κB activity couples cell-cycle withdrawal to myogenic differentiation" [1]. After the article was published, the first author revealed that the tubulin blots in Figures 1A, 3E, and 4A are from unrelated samples. The lead author and co-authors apologise to the readers, reviewers and editors for publishing this erroneous data.
