Abstract

Official abstract text for this publication.

The invention provides compositions and methods for reducing expression of a target gene in a cell, involving contacting a cell with an isolated double stranded nucleic acid (dsNA) in an amount effective to reduce expression of a target gene in a cell. The dsNAs of the invention possess a single stranded extension (in most embodiments, the single stranded extension comprises at least one modified nucleotide and/or phosphate back bone modification). Such single stranded extended Dicer-substrate siRNAs (DsiRNAs) were demonstrated to be effective RNA inhibitory agents compared to corresponding double stranded DsiRNAs.

First claim

Opening claim text (preview).

The invention claimed is: 1. An isolated double stranded nucleic acid comprising a first oligonucleotide strand having a 5′ terminus and a 3′ terminus and a second oligonucleotide strand having a 5′ terminus and a 3′ terminus, wherein each said 5′ terminus comprises a 5′ terminal nucleotide and each said 3′ terminus comprises a 3′ terminal nucleotide, wherein: said first strand is 25-30 nucleotide residues in length, wherein starting from the 5′ terminal nucleotide (position 1) po…
