Retraction

The article entitled: “Aberrant methylation to heparan sulfate glucosamine 3-O-sulfotransferase 2 genes as a biomarker in colorectal cancer” by Tokuyama Y, Takahashi T, Okumura N, Nonaka K, Kawaguchi Y, Yamaguchi K, Osada S, Gazdar A and Yoshida K, published in Anticancer Research, 2010, 30(12): pp. 4811-4818 is retracted.

This action, requested by the authors, is based on the findings and recommendations of an Internal Review Committee at the University of Texas Southwestern, Dallas, TX, USA, as the GAPDH loading control in Figure 1A of the article (p.4813) appears to be a modified version of a figure previously published elsewhere.
