Retraction Statements. Paper by Gu and Ye [2010;19:105–116]

It is flattering to hear that the publishers, editors, and reviewers are in agreement that this paper, most of which derives from ideas and experiments from my lab, represents a significant contribution to the scientific literature. My long-standing policy, however, has been to publish my work and ideas under my own name and those of my collaborators when we collectively decide that this would be appropriate. Neither Dr. Gu, who was a postdoctoral fellow in my lab in 2005 at Concordia University, nor Dr. Ye, has ever asked me for strains or chemicals, nor have I sent them any, metK84 included, although all the strains mentioned in the paper are in my collection.
