Abstract

Recently, several advances have been made in the activation and deactivation of gene expression using light. These developments are based on the application of small molecule inducers of gene expression, antisense- or RNA interference-mediated gene silencing, and the photochemical control of proteins regulating gene function. The majority of the examples employ a classical ‘caging technology’, through the chemical installation of a light-removable protecting group on the biological molecule (small molecule, oligonucleotide, or protein) of interest and rendering it inactive. UV light irradiation then removes the caging group and activates the molecule, enabling control over gene activity with high spatial and temporal resolution.
