Imaging tri-fusion multimodality reporter gene expression in living subjects.
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, fluorescence and positron emission tomography (...
متن کاملConstruction and validation of improved triple fusion reporter gene vectors for molecular imaging of living subjects.
Multimodality imaging using several reporter genes and imaging technologies has become an increasingly important tool in determining the location(s), magnitude, and time variation of reporter gene expression in small animals. We have reported construction and validation of several triple fusion genes composed of a bioluminescent, a fluorescent, and a positron emission tomography (PET) reporter ...
متن کاملOptical imaging of cardiac reporter gene expression in living rats.
BACKGROUND Studies of cardiac gene transfer rely on postmortem analysis using histologic staining or enzyme assays. Noninvasive imaging of the temporal and spatial characteristics of cardiac gene expression in the same subject offers significant advantages. METHODS AND RESULTS Rats underwent direct myocardial injection via left thoracotomy with adenovirus-expressing firefly luciferase (Ad-CMV...
متن کاملVisualizing gene expression in living mammals using a bioluminescent reporter.
Control of gene expression often involves an interwoven set of regulatory processes. As information regarding regulatory pathways may be lost in ex vivo analyses, we used bioluminescence to monitor gene expression in living mammals. Viral promoters fused to firefly luciferase as transgenes in mice allowed external monitoring of gene expression both superficially and in deep tissues. In vivo bio...
متن کاملOptical imaging of Renilla luciferase reporter gene expression in living mice.
Imaging reporter gene expression in living subjects is a rapidly evolving area of molecular imaging research. Studies have validated the use of reporter genes with positron emission tomography (PET), single photon emission computed tomography (SPECT), MRI, fluorescence with wild-type and mutants of green fluorescent protein, as well as bioluminescence using Firefly luciferase enzyme/protein (FL...
