Abstract
Caged morpholino oligonucleotides (cMOs) are synthetic tools that allow light-inducible gene silencing in live organisms. Previously reported cMOs have utilized hairpin, duplex, and cyclic structures, as well as caged nucleobases. While these antisense technologies enable efficient optical control of RNA splicing and translation, they can have limited dynamic range. A new caging strategy was developed where the two MO termini are conjugated to an internal position through a self-immolative trifunctional linker, thereby generating a bicyclic cMO that is conformationally resistant to RNA binding. The efficacy of this alternative cMO design has been demonstrated in zebrafish embryos and compared to linear MOs and monocyclic constructs.
