There is a December 2013 correction that addresses some figure problems. The correction can be found here: https://journals.plos.org/plosone/article?id=10.1371/annotation/f56711b9-78f1-49ed-9116-872913e98867 The text of the correction reads:
However, the paper has several more problems, all of which have been reported to the journal in 2014, more than 5 years ago, but not yet addressed.
The cPLA2 panels shown in Figures 2A and 4A appear to look very similar to each other. Marked with blue boxes. Note that the panels are stretched differently, so this is not a simple duplication. Also note that the panels represent different experiments. This issue was not addressed in the 2013 correction, but has been reported to the journal in 2014.
Figures 4C, 6C, and 7A.

"Following the publication of this article [1] and correction [2], additional concerns were raised regarding results reported in multiple figures. Specifically, the following results appear similar despite representing different experimental conditions:
The corresponding author stated that multiple western blot experiments were performed and imaged at the same time. They acknowledged that errors occurred in the preparation of the figures and annotation of raw images, and apologized for these errors. The corresponding author accepted that the issues with the published figures cannot be fully resolved, and requested that the article be retracted.
In light of the concerns affecting multiple figure panels and the errors in the raw underlying data that question the reliability of these data, the PLOS ONE Editors retract this article.
ITL, CCL, LDH and CMY agreed with the retraction. SEC and YCH either did not respond directly or could not be reached."
