Reporter genes integrated into the genome are a powerful tool to reveal effects of regulatory elements and local chromatin context on gene expression. However, so far such reporter assays have been of low throughput. Here, we describe a multiplexing approach for the parallel monitoring of transcriptional activity of thousands of randomly integrated reporters. More than 27,000 distinct reporter ...

Magnetic resonance imaging (MRI) is one of the most important imaging technologies used in clinical diagnosis. Reporter genes for MRI can be applied to accurately track the delivery of cell in cell therapy, evaluate the therapy effect of gene delivery, and monitor tissue/cell-specific microenvironments. Commonly used reporter genes for MRI usually include genes encoding the enzyme (e.g., tyrosi...

a stable agrobacterium-mediated transformation system was established using bialaphos as the selective agent in soybeans [glycine max (l.) merr.]. the cotyledonary node explants of the soybean cultivar ‘ny-1001’ were inoculated with the agrobacterium tumefaciens strain eha105, harboring the vector pcambia3301 containing the gus gene as the reporter gene and the bar gene conferring bialaphos res...

Targeting a gene expression reporter, usually the green fluorescent protein (GFP), to the nucleus via a translationally fused nuclear localization signal (NLS) greatly facilitates recognition and identification of the reporter-expressing cells in Caenorhabditis elegans. Presently circulating nematode transcriptional gene expression vectors use the viral NLS from simian virus 40 (SV40) large T a...

In our recent paper, we reported an aminoglycoside-sensing RNA in the leader RNA of the aminoglycoside acetyl transferase (AAC) and aminoglycoside adenyl transferase (AAD), enzymes that confer resistance to aminoglycoside antibiotics through modification of the drugs. Our study explains a well-known phenomenon: the induction of expression levels of the AAC/AAD proteins on addition of aminoglyco...

The hormone combination of insulin, dexamethasone and prolactin induced accumulation of preproepidermal growth factor (EGF) mRNA in HC11 mouse mammary epithelial cells 16-24 h after the hormones were added to the cultures. Individual hormones or combinations of two of the hormones had no effect on EGF mRNA concentrations. The same hormone combination was capable of inducing expression of a repo...
