Retraction to: Cell Death and Disease (2012) 3, e383; doi:10.1038/cddis.2012.126; published online 30 August 2012

The Editorial Board of Cell Death and Disease is retracting the above article (PMID 22932725).

A reader contacted the Editors about apparent duplications in Figures 1b and 2c, and possible splicing of an image in Figure 3c. Concerns were subsequently raised about the similarity of the tubulin loading controls in Figure 1b to those that appeared in Figure 1c of Cell Death and Differentiation 2006; 13: 1554–63 (PMID 16341121), a paper that was retracted by the authors on 6 December 2013.

Because the Authors were unable to provide the original source files that were used to generate the figures in question, the Editorial Board is retracting this publication.
