Branched RNA nanostructures for RNA interference

Chem Commun (Camb). 2011 Aug 7;47(29):8367-9. doi: 10.1039/c1cc11780g. Epub 2011 Jun 21.

Abstract

Branched RNAs with three- or four-way junctions were designed by assembling single-stranded RNA for RNA interference. Human Dicer transformed branched RNAs into about 20 base pairs of double-stranded RNA, which is a standard siRNA species. Our tetramer design provides a potent silencing effect over a period of 5 days.
