The authors wish to retract the article titled “DNA Methylation Profiles of Lymphoid and Hematopoietic Malignancies,” which was published in the May 1, 2004, issue of Clinical Cancer Research (1).

After a thorough institutional investigation, it was concluded that there was incontrovertible evidence of improper manipulation of figures. It seems that the GAPDH loading controls of Fig. 1B—CDH13 and Fig. 1B—DcR1 (p. 2931) were created by manipulating (cropping of various lanes) Fig. 1A of the referenced article. Dr. Takao Takahashi has accepted the responsibility for Fig. 1B.
