We wish to retract the article titled “The Chemokine Receptor CXCR6 and Its Ligand CXCL16 Are Expressed in Carcinomas and Inhibit Proliferation”, which was published in the June 15, 2008 issue of Cancer Research (1).
After a thorough institutional investigation, it was recently concluded that key results contributed by the first author cannot be reproduced. These results include the detection of CXCR6 and CXCL16 on the cell surface by FACS analysis, the knockdown of these proteins, and the effects of this knockdown on proliferation rates in vivo and in vitro. Five of the 6 authors agreed to this Retraction. Attempts on the part of the journal office to contact the first author, Joost Meijer, to determine whether or not he agreed with the Retraction were unsuccessful.
