Title:
IMPROVED INHIBITOR NUCLEIC ACIDS
Document Type and Number:
WIPO Patent Application WO2006001810
Kind Code:
A3
Abstract:
The present invention provides methods and compositions for attenuating expression of a target gene in vivo. In general, the method includes administering RNAi constructs (such as small-interfering RNAs (i.e., siRNAs) that are targeted to particular mRNA sequences, or nucleic acid material that can produce siRNAs in a cell), in an amount sufficient to attenuate expression of a target gene by an RNA interference mechanism. In particular, the RANi constructs include one or more modifications to improve serum stability and cellular uptake and to avoid non-specific effect.
