Xenograft data on uptake of fluorocoxib A. Fluorocoxib A was administered by retro-orbital injection and the animals monitored for fluorescence 3.5 h later using a Xenogen camera. The head-and-neck cancer, 1483, expresses COX-2 whereas the colon cancer, HCT116, does not express COX-2. Reproduced with permission from ref (106). 2010. American Association for Cancer Research.
