Corrections to: Oncogene (2003) 22, 8961–8982. doi:10.1038/sj.onc.1207230

Owing to a production error, the beginning of the first sentence on p. 8962 was omitted. The correct sentence should read: ‘Several reports revealed that casein kinase II can also phosphorylate IκBα to promote its degradation (Schwarz et al., 1996; Miyamoto et al., 1998; Romieu-Mourez et al., 2001; Shen et al., 2001; Kato et al., 2003).’ The phenotype of relA-deficient mice was also listed incorrectly as RelA+ at three places in the last paragraph of p. 8965. The correct description is relA−/−.
