Intracellular Build-up RNAi with Single-Strand Circular RNAs as siRNA Precursors
Abstract
We herein report a new approach for RNA interference, so-called “build-up RNAi” approach, where single-strand circular RNAs with a photocleavable unit or disulfide moiety were used as siRNA precursors. The advantages of using these circular RNA formats for RNAi were presented in terms of immunogenicity and cellular uptake.
