wavelength-selective photo-cage pair for mRNA

RNA Element·Research·Since 2020

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

Summary

This tool is a pair of wavelength-selective photo-cages conjugated to the 5′-UTR of mRNA to suppress translation until illumination. Selective photocleavage with different wavelengths enables sequential optical activation of two distinct mRNAs in the same mammalian cell with single-cell spatiotemporal resolution.

Usefulness & Problems

Why this is useful

The system provides optical control over mRNA translation with both spatial and temporal precision at the single-cell level. Its key utility is multiplexed regulation, because two different mRNAs can be activated sequentially by using photo-cages that respond to different wavelengths of light.

we synthesized a pair of ‘photo-cages’ which can be selectively cleaved from mRNA upon photo-irradiation with different wavelengths of light. Sequential photo-activation of two mRNAs enabled precise optical control of translation of two unique transcripts.

Source:

We demonstrate sequential optical activation of two types of mRNAs in the same mammalian cell through the sequential photocleavage of small molecule caging groups (‘photo-cages’) tethered to the 5′ untranslated region (5′-UTR) of an mRNA.

Problem solved

It addresses the problem of independently controlling translation of multiple mRNA species in the same mammalian cell using light. The approach specifically solves how to keep mRNAs translationally repressed until user-defined photo-irradiation and then release them in sequence.

The photo-cages are tethered to the 5′-UTR of mRNA, and translation is activated by photo-release after irradiation with different wavelengths of light. The available evidence supports use in mammalian cells, but it does not specify delivery format, expression workflow, or detailed conjugation chemistry beyond photo-cage attachment to mRNA.

The supplied evidence is limited to a single 2020 source and focuses on translation suppression and sequential activation in mammalian cells. Specific cage chemistries, exact activation wavelengths, quantitative dynamic range, and validation across broader cell types or in vivo settings are not provided here.
