摘要:
One aspect of the present invention relates to double-stranded RNA (dsRNA) agent capable of inhibiting the expression of a target gene. The sense strand of the dsRNA agent comprises at least one thermally destabilizing nucleotide, and at least one said thermally destabilizing nucleotide occurring at a site opposite to the seed region (positions 2-8) of the antisense strand; and the antisense strand of the dsRNA agent comprises at least two modified nucleotides that provide the nucleotide a steric bulk that is less than or equal to the steric bulk of a 2'-OMe modification, wherein said modified nucleotides are separated by 11 nucleotides in length. Other aspects of the invention relates to pharmaceutical compositions comprising these dsRNA agents suitable for therapeutic use, and methods of inhibiting the expression of a target gene by administering these dsRNA agents, e.g. , for the treatment of various disease conditions.

摘要:
Recombinant nucleic acid molecules are provided that form hair pin structures and can be used to down-regulate gene expression. For example, a nucleic acid molecule can comprise a flanking and lower stem loop sequence from a mir-16 gene; an antisense target sequence; a mir-30 loop sequence; a complement of the anti-sense target sequence; and a lower stem loop complementary to the mir-16 sequence. Methods for down regulating gene expression in a cell using such recombinant nucleic acid molecules are also provided.
摘要:
The present invention includes multivalent nucleic acid complexes of nucleic acid molecules having two or more target-specific regions, in which the target-specific regions are complementary to a single target gene at more than one distinct nucleotide site, and/or in which the target regions are complementary to more than one target gene or target sequence. One oligonucleotide strand of the complex is nicked and thereby inactivated. Also included are methods of using the complexes for treatment of a variety of diseases and infections.

摘要:
This disclosure provides formulations and compounds for use in treating disease by gene silencing and, more specifically, to formulations and compositions having multiple double- stranded nucleic acid complexes, each double- stranded nucleic acid complex comprising an antisense strand and a continuous passenger strand or a discontinuous passenger strand, where the composition decreases expression of one or more mRNA, and to uses of such formulations and compositions to treat or prevent diseases or conditions associated with inappropriate gene expression.
摘要:
The present invention relates to a novel siRNA structure and to the use thereof, and more particularly, to a siRNA molecule and to a target gene silencing method using same, wherein the siRNA molecule is a double-stranded siRNA molecule comprising an antisense strand and a sense strand, and at least one or more single nucleotide bulges induced by the introduction of single nucleotides are present on the antisense strand of the siRNA, specifically at the second position of the 5' end. The present invention provides a siRNA molecule having a novel structure, which exhibits superior efficiency of target gene silencing, minimizes off-target effects caused by antisense strands, and thus has improved target selectivity. Therefore, the siRNA molecule of the present invention can be widely used in siRNA-based gene silencing technologies such as a gene therapy or the like in lieu of conventional siRNA molecules.
