    摘要: The present invention provides compositions and methods for inhibiting gene silencing by the RNAi pathway. The RNAi inhibitors of the invention have a reverse complement (RC) region to the target molecule of interest (e.g., miRNA) in association with at least one flanking region coupled to either at the 3′ or 5′ end of the RC region. The flanking regions can be single-stranded or can have one or more regions of double stranded nucleic acid with or without a hairpin loop. The RNAi inhibitors described herein can inhibit endogenous targets, including but not limited to microRNAs, or piRNAs, or can be used to inhibit the effects of exogenously introduced molecules, such as synthetic siRNAs, siRNAs expressed from vector constructs (e.g., viral expression systems), or siRNAs generated by enzymatic methods. Inhibition is specific, potent, prolonged, and can be performed on a single target or multiple targets simultaneously.

    摘要: Methods and compositions for performing RNA interference comprising a wide variety of stabilized siRNAs suitable for use in serum-containing media and for in vivo applications, such as therapeutic applications, are provided. These siRNAs permit effective and efficient applications of RNA interference to applications such as diagnostics and therapeutics through the use of one or more modifications including orthoesters, terminal conjugates, modified linkages and 2′ modified nucleotides. Uniquely modified siRNAs have been developed that reduces off-target effects incurred in gene-silencing. The modifications include phosphorylation of the first 5′ terminal antisense nucleotide; 2′ carbon modifications of the first and second or first, second, and third 5′ terminal antisense nucleotides; and optionally 2′ carbon modifications of the first and second or first, second, and third 5′ terminal sense nucleotide. Control and exaequo molecules are also provided. siRNA molecules and related control, trackability and exaequo agents with specific stability modifications were developed.
