in this study, an efficient agrobacterium-mediated transformation method was developed forpomegranate (punica granatum l.), a difficult-to-transform plant. in vitro shoot segments wereinoculated with agrobacterium tumefaciens strain lba4404 harboring the binary vectorpbi121 carrying the neomycin phosphotransferase (nptii) gene as a selectable marker and β-glucuronidase (gus) gene as a reporter....

While high-throughput genome-wide approaches are useful to identify important regulatory regions, traditional reporter gene methodologies still represent the ultimate steps in fine structure analysis of transcriptional control elements. However, there are still several inherent limitations in the currently available transient and stable transfection systems often leading to aberrant function of...

UNLABELLED A reporter gene can provide important information regarding the specificity and efficacy of gene or cell therapies. Although reporter genes are increasingly used in experimental and clinical studies, a highly specific yet nonimmunogenic reporter that can track genes and cells in vivo by multiple imaging technologies still awaits development. In this study, we constructed a versatile ...

Noninvasive reporter gene imaging is a component of molecular imaging. Reporter imaging can provide noninvasive assessments of endogenous biologic processes in living subjects and can be performed using different imaging modalities. This review will focus on radionuclide-based reporter gene imaging as developed and applied in preclinical and clinical studies. Examples of different reporter syst...

The molecular mechanisms regulating the activity of the TCRα gene are required for the production of the circulating T cell repertoire. Elements of the mouse TCRα locus control region (LCR) play a role in these processes. We previously reported that TCRα LCR DNA supports a gene expression pattern that mimics proper thymus-stage, TCRα gene-like developmental regulation. It also produces transcri...

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 (...

Noninvasive molecular imaging using reporter genes is a relatively recent field in biomedical imaging that holds great promises for disease diagnosis and therapy. As modern medicine is moving towards personalized medicine, targeted biomolecule based therapies is gaining popularity that requires careful and systematic validation. Reporter genes have emerged as important generalizable tools to ov...

This study evaluated the transcriptional regulation of four reporter genes in Saccharomyces cerevisiae by the human tumor suppressor protein p53. The S. cerevisiae ADE2, HIS3 and URA3 genes were used with nutritional selections and the E. coli LacZ gene was used to quantitate reporter gene activation. DNA elements containing binding sites for p53 were introduced upstream of several 5' truncated...
