This article (1) has been retracted at the request of the editors. Following a joint institutional investigation by the Birmingham VA Medical Center and the University of Alabama at Birmingham, the primary affiliations for several of the authors, it was determined that the same histologic image was used to represent results from different animals and treatment conditions in Fig. 4A. The original research records related to the figures were not available during the review. Therefore, the institutions were not able to determine which of the published images were correct and recommended retraction; upon internal review, the editors agreed with this recommendation.
A copy of this Retraction Notice was sent to the last known e-mail addresses for all four authors. Two authors (S.M. Meeran and S.K. Katiyar) did not agree to the retraction; the two remaining authors (S.K. Mantena and C.A. Elmets) did not respond.
