Retraction: Demethylation-Linked Activation of Urokinase Plasminogen Activator Is Involved in Progression of Prostate Cancer

This article (1) is being retracted at the request of the Cancer Research editors. The University of Illinois at Chicago notified the AACR that following an institutional review, it was determined that numerous panels in Fig. 6B had been falsified. An internal investigation by the editors determined that the same lung tissues were used in different panels with apparent differences in the fluorescence signal, thus inaccurately depicting different lung tissues. Specifically, the same lung tissue was used in the following panels: panels #18, #16, and #25; panels #14 and #26; panels #35, #06, and #03; panels #20 and #30. To ensure that the research record is correct, the Cancer Research editors have decided to retract the article.

A copy of this retraction notice was sent to the last known email addresses for all four authors. One author (J.S. Rao) did not agree to the retraction; the three remaining authors (S.M.K. Pulukuri, N. Estes, and J. Patel) did not respond.
