2′-Deoxy-2′-flouro-5-methyl-1-β-d-arabinofuranosyluracil (FMAU) has been evaluated in HT-29 cells as a potential positron emission tomography (PET) radiotracer for imagingHSV-tkgene expression in vivo. In vitro experiments demonstrate that the accumulation of [14C]-FMAU inHSV-tk-expressing cells is 2.4-fold (p< .02), 4.0-fold (p< .001), and 5.3-fold (p< .001) higher than the wild-type cells at 1, 3, and 5 hr, respectively. In vivo studies revealed that the tumor uptake inHSV-tk-expressing cells was 2.3-fold (p< .001), 3.0-fold (p< .001), and 5.5-fold (p< .001) higher than the control cells at 1, 2, and 5 hr, respectively. FMAU was found to be more sensitive compared to our earlier studies using 9-[(3-18F-fluoro-1-hydroxy-2-propoxy)methyl]-guanine ([18F]-FHPG) and 9-(4-[18F]-fluoro-3-hydroxy-methylbutyl)guanine ([18F]-FHBG) in the same cell lines, although, the specificity was less than FHBG. These results suggest that while FMAU labeled with PET isotopes may be useful for imagingHSV-tk-expressing tumors in vivo, multitracer studies across additional tumor models are necessary in order to identify an optimal PET radiotracer.
