The above article, published online on 09 March 2011 in Wiley Online Library (wileyonlinelibrary.com), has been retracted by agreement between the journal's Editor in Chief, Dr. Gregory Gores, and Wiley Periodicals LLC. The retraction has been agreed following a review by The Ohio State University which found evidence of figure mislabeling and manipulation in Figures 2D, 4C, and 6A. Similar manipulations were identified in 2017 during an Ohio State investigation in which the article's corresponding author, Dr. Ching-Shih Chen, was found to be responsible. None of the other authors were investigated as part of these concerns. As a result, the Editor-in-Chief no longer has confidence in the results and conclusions drawn.
