The authors wish to retract the article titled “Mechanistic Analysis of the Role of BLCA-4 in Bladder Cancer Pathobiology,” which was published in the August 15, 2005 issue of Cancer Research (1).

The studies performed in the article used a cDNA sequence that at the time of publication the authors believed to encode BLCA-4. The authors feel that although this is still likely the case, there currently exists some uncertainty whether the cDNA sequence indeed encoded this protein. The authors believe that the work performed in the article is fully supported, but that the conclusions reached may differ based upon this potential; therefore, the authors felt that retraction of the article was warranted, and sincerely apologize for any inconvenience this might have caused.

Two of the three authors agreed to this Retraction. Attempts on the part of the authors to contact the second author, Thu-Suong Van Le, were unsuccessful.
