British Journal of Pharmacology, volume 165(6): 1773-1788, published in March 2012; DOI 10.1111/j.1476-5381.2011.01673.x.

The above article, published by the British Journal of Pharmacology in March 2012 (http://onlinelibrary.wiley.com/doi/10.1111/j.1476-5381.2011.01673.x/full), has been retracted by agreement between the authors, the Journal Editor in Chief and John Wiley & Sons Ltd. The authors wish to state that in preparation of the original manuscript errors occurred resulting in duplication. This issue relates specifically to Figures 2A and 2B, lanes 3-5 of the pJNK1/2 in Figure 3B and lanes 1-3 of the pJNK1/2 blot from Figure 3C. In addition, duplication has occurred in lanes 1-9 of the total MEK1/2 blot (left) and lanes 1-9 of the tubulin blot from Figure 6G JBC 280 (right). The authors apologize for the mistake. Unfortunately, the authors are not able to provide the original data for these figures.
