title: Development of light-responsive BNA toward the spatiotemporal control of gene expression.
abstract: We designed and synthesized light-responsive BNA (bridged nucleic acid), which has a photolabile group at the bridged structure. Light-Responsive BNA can change its structure by a two stages process: photoirradiation followed by nucleophilic treatment. In oligonucleotides containing light-responsive BNA moieties, binding affinity with complementary single-stranded RNA was lost upon photoirradiation, but could be restored by nucleophilic treatment.(1)
