caged NF-κB DNA decoy

RNA Element·Research·Since 2011

Also known as: caged DNA decoy, NF-κB DNA decoy

Taxonomy: Mechanism Branch / Component. Workflows sit above the mechanism and technique branches rather than replacing them.

Summary

The caged NF-κB DNA decoy is a photoregulated oligonucleotide decoy in which photoremovable protecting groups are installed on nucleobases within an NF-κB decoy sequence. UV irradiation removes the caging groups, restores decoy hybridization and NF-κB binding activity, and enables light-controlled regulation of NF-κB-driven transcription in mammalian cells.

Usefulness & Problems

Why this is useful

This tool enables temporal optical control over NF-κB decoy function rather than constitutive transcription factor sequestration. It is useful for probing NF-κB-dependent transcriptional programs in mammalian cells with externally applied light as the activating input.

Problem solved

Conventional NF-κB DNA decoys lack precise on-demand activation once delivered to cells. This tool addresses that limitation by keeping the decoy inactive until UV exposure restores transcription factor binding and decoy-mediated inhibition of NF-κB-driven transcription.

Problem links

Need conditional recombination or state switching

Derived

The caged NF-κB DNA decoy is a photoregulated oligonucleotide decoy in which photoremovable protecting groups are installed on nucleobases within an NF-κB decoy sequence. UV irradiation removes the caging groups, restores decoy hybridization and NF-κB binding activity, and enables light-controlled regulation of NF-κB-driven transcription in mammalian cells.

Need precise spatiotemporal control with light input

Derived

The caged NF-κB DNA decoy is a photoregulated oligonucleotide decoy in which photoremovable protecting groups are installed on nucleobases within an NF-κB decoy sequence. UV irradiation removes the caging groups, restores decoy hybridization and NF-κB binding activity, and enables light-controlled regulation of NF-κB-driven transcription in mammalian cells.

Need tighter control over gene expression timing or amplitude

Derived

The caged NF-κB DNA decoy is a photoregulated oligonucleotide decoy in which photoremovable protecting groups are installed on nucleobases within an NF-κB decoy sequence. UV irradiation removes the caging groups, restores decoy hybridization and NF-κB binding activity, and enables light-controlled regulation of NF-κB-driven transcription in mammalian cells.

The construct is an NF-κB DNA decoy oligonucleotide bearing photoremovable protecting groups on nucleobases. Functional activation depends on UV irradiation to remove the caging groups, and the reported cellular validation was performed in mammalian cells using an NF-κB-driven secreted alkaline phosphatase reporter assay.

The available evidence is limited to a single cited study and a mammalian-cell reporter context. Activation requires UV irradiation, and the supplied evidence does not describe broader target validation, in vivo use, quantitative performance, or applications beyond NF-κB-driven transcription.

The reported design directly links photochemistry to restoration of both DNA:DNA hybridization and transcription factor binding. It was validated in mammalian cells by light-controlled regulation of an NF-κB-driven secreted alkaline phosphatase reporter, and the source describes it as the first caged DNA decoy for photochemical regulation of gene expression in mammalian cells.
