Title:
METHODS AND COMPOSITIONS FOR ENHANCING THE EFFICACY AND SPECIFICITY OF RNA SILENCING
Document Type and Number:
WIPO Patent Application WO2006015389
Kind Code:
A3
Abstract:
The present invention provides methods of enhancing the efficacy and specificity of RNA silencing. The invention also provides compositions for mediating RNA silencing. In particular, the invention provides siRNAs, siRNA-like molecules, shRNAs, vectors and transgenes having improved specificity and efficacy in mediating silencing of a target gene. Therapeutic methods are also featured.
