Imaging of gene expression in living cells and tissues.
It is possible to observe gene expression within single cells using a tetracycline inducible promoter for activation. Transcription can be observed by using a fluorescent fusion protein to bind nascent RNA. Ultimately, it is desirable to activate a reporter gene within a single cell with only photons. This is achieved by preparing a chemically altered transcription factor that is functionally u...
متن کاملImaging real-time gene expression in living yeast.
INTRODUCTIONThis protocol describes the application of the MS2 system to the yeast Saccharomyces cerevisiae. ASH1 mRNA tagged with six MS2 repeats (6MBSs) is used to follow the localization of the ASH1 mRNA particles to the bud tip of a haploid yeast cell. W303 yeast cells transformed with pG14-MS2-GFP and pGAL-lacZ-MS2-ASH1 are grown on select medium lacking tryptophan and leucine. RNA express...
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 کاملImaging 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 (...
