Imaging reporter gene expression in living subjects with various imaging modalities is a rapidly accelerating area of research. Applications of these technologies to cancer research, gene therapy, and transgenic models are rapidly expanding. We report construction and testing of several triple fusion reporter genes compatible with bioluminescence,(More)
Earlier studies involving comparison of different reporter probes have shown conflicting results between pyrimidine nucleosides [e.g., 2'-fluoro-2'-deoxy-1-β-d-arabinofuranosyl-5-iodouracil (FIAU)] and acycloguanosine derivatives [e.g., penciclovir (PCV), 9-(4-fluoro-3-hydroxymethylbutyl)guanine (FHBG)]. We hypothesized that this reported discrepancy may be(More)
UNLABELLED Mitochondrial membrane potential (DeltaPsim)-dependent enhanced uptake of phosphonium salts, including (3)H-tetraphenylphosphonium ((3)H-TPP), in tumor cells, suggests the potential use of phosphonium salts as tracers for tumor imaging. In this study, we characterize the tumor accumulation of (3)H-TPP and compare it with (18)F-FDG in cell culture(More)
BACKGROUND We have previously validated the use of micro-positron emission tomography (microPET) for monitoring the expression of a single PET reporter gene in rat myocardium. We now report the use of a bicistronic adenoviral vector (Ad-CMV-D2R80a-IRES-HSV1-sr39tk) for linking the expression of 2 PET reporter genes, a mutant rat dopamine type 2 receptor(More)
