The authors wish to retract the article entitled “Functional Characterization of the Bladder Cancer Marker, BLCA-4,” which was published in the February 15, 2004, issue of Clinical Cancer Research (1).

The studies described in the article used a cDNA sequence that, at the time of publication, the authors believed to encode BLCA-4. Although this is still likely the case, there currently exists some uncertainty about whether the cDNA sequence indeed encoded this protein. The work described in the article is fully supported, but the conclusions reached may differ based on this potential. The authors apologize for any inconvenience.
