    摘要: The present disclosure provides a non-naturally occurring miRNA having a stem-loop structure comprising a scaffold derived from a first endogenous miRNA (e.g., miR-196a-2 or miR-204), a mature strand derived from a second endogenous miRNA, and a star strand sequence that is at least partially complementary to the mature strand sequence. The present disclosure also provides a non-naturally occurring miRNA having a stem-loop structure comprising a scaffold derived from an endogenous miRNA (e.g., miR-196a-2 or miR-204), a mature strand designed t be at least partially complementary to a target RNA, and a star strand sequence that is at least partially complementary to the mature strand sequence. The methods and compositions of the disclosure may be used to mediate gene silencing via the RNAi pathway.

    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.
