Retraction to: Cell Death and Differentiation https://doi.org/10.1038/sj.cdd.4401420, published online 26 March 2004

The Editors have retracted this article. Concerns have been raised regarding a number of figures, specifically:

  • Figure 1a: there appear to be irregularities in all four bands.

  • Figure 2: there appear to be duplications in the / and -/+ sections of the PARP and Cleaved casp 3 bands.

  • Figure 6: there appears to be a duplication in the wt band for P-Erk 1-2.

The editors, therefore, no longer have confidence in the results and conclusions of this article. The authors have not responded to correspondence regarding this retraction notice.
