    摘要： Double-stranded nucleic acid molecules (100, 200, 300, 400, 500 and 600) are provided comprising a sense strand (110, 210, 310, 410, 510 and 610) and an antisense strand (120, 220, 320, 420, 520 and 620). The sense strand has a 3′-overhang (115, 215, 315, 415, 515 and 615) of from four to eight nucleotides. The double-stranded nucleic acid molecules include double-stranded RNA (dsRNA), double-stranded DNA (dsDNA), double-stranded DNA-RNA (sense-antisense) hybrid and double-stranded RNA-DNA (sense-antisense) hybrid. The double-stranded nucleic acid molecules have beneficial properties in terms of unaided cellular delivery (e.g. in the absence of a cationic agent), cellular delivery and release of the antisense strand in a cell as a single-stranded molecule and the delivery of the antisense strand into the nucleus of a cell as a single-stranded molecule. Related compositions, cells, uses and methods are also provided.

    摘要： The invention is directed to compositions and methods for selectively reducing the expression of a gene product from a desired target gene in a cell, as well as for treating diseases caused by the expression of the gene. More particularly, the invention is directed to compositions that contain double stranded RNA ("dsRNA"), and methods for preparing them, that are capable of reducing the expression of target genes in eukaryotic cells. The dsRNA has a first oligonucleotide sequence that is between 25 and about 30 nucleotides in length and a second oligonucleotide sequence that anneals to the first sequence under biological conditions. In addition, a region of one of the sequences of the dsRNA having a sequence length of at least 19 nucleotides is sufficiently complementary to a nucleotide sequence of the RNA produced from the target gene to trigger the destruction of the target RNA by the RNAi machinery.
