    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: The present invention provides improved hairpin and fractured hairpin constructs for use in gene silencing through the RNA interference pathway. An exemplary short hairpin polynucleotide for use in gene silencing can include a polynucleotide having from about 42 nucleotides to about 106 nucleotides configured for being processed by Dicer. The polynucleotide can include a first region having from about 19 to about 35 nucleotides, a loop region coupled to the first region, the loop region having from about 4 to about 30 nucleotides, and a second region having from about 19 to about 35 nucleotides and having at least about 80% complementarity to the first region. Optionally, one of the first region or second region can have an overhang having less than about 6 nucleotides. Also, the short hairpin can be formed of a plurality of polynucleotides that cooperate to form a hairpin structure.

    摘要: The disclosure provides methods for inhibiting the activity of a miRNA cluster in a cell, and also for screening a cell for a phenotype(s) of interest resulting from inhibition of a miRNA cluster. The methods use a cluster pool which comprises at least one miRNA inhibitor specific for each miRNA in the miRNA cluster. MiRNA inhibitors are described that induce apoptosis in breast cancer cells and hence are useful in the treatment of breast cancer. The disclosure also provides pharmaceutical compositions which are useful for the treatment of breast cancer; methods for inducing the nuclear translocation of NF-κB in a breast cancer cell; methods for inducing the nuclear translocation of c-Jun in a breast cancer cell; method for inhibiting the nuclear translocation of NF-κB in a breast cancer cell; and methods for providing prognostic medical information relating to breast cancer progression.
