  • Publication number: 20110251258
    Abstract: The invention relates to improved double-stranded RNAi constructs (sometimes referred to as “solo-rxRNA”) and uses thereof. The construct comprises a structure formed in some aspects of the invention by two identical single-stranded polynucleotides, with the structure having two double-stranded stem regions (each having less than 21 base pairs) and a loop or bulge having about 4 to 11 nucleotides on each strand. The construct is resistant to cleavage by Dicer or other Dicer-like RNase III enzymes and is capable of being loaded into a RISC complex to effect RNA interference. In addition, the nucleotides of the present hairpin constructs may be modified to greatly enhance functionality, such as stability and specificity.

  • Publication number: 20110039914
    Abstract: The invention relates to improved RNAi constructs and uses thereof. The construct has a double stranded region of 19-49 nucleotides, preferably 25, 26, or 27 nucleotides, and preferably blunt-ended. The construct has selective minimal modifications to confer an optimal balance of biological activity, toxicity, stability, and target gene specificity. For example, the sense strand may be modified (e.g., one or both ends of the sense strand is/are modified by four 2?-O-methyl groups), such that the construct is not cleaved by Dicer or other RNAse III, and the entire length of the antisense strand is loaded into RISC. In addition, the antisense strand may also be modified by 2?-O-methyl group at the 2nd 5?-end nucleotide to greatly reduce off-target silencing. The constructs of the invention largely avoids the interferon response and sequence-independent apoptosis in mammalian cells, exhibits better serum stability, and enhanced target specificity.

  • Publication number: 20090170197
    Abstract: The present invention relates to nucleic acid molecules such as ribozymes, DNAzymes, short interfering RNA (siRNA), short interfering nucleic acid (siNA), and antisense which modulate the synthesis, expression and/or stability of an mRNA encoding one or more receptors of vascular endothelial growth factor, such as flt-1 (VEGFR1) and/or KDR (VEGFR2). Nucleic acid molecules and methods for the inhibition of angiogenesis and treatment of cancer and other conditions associated with VEGF-R are provided, optionally in conjunction with other therapeutic agents such as interferons.

  • Publication number: 20090131360
    Abstract: The present invention provides compositions and methods for inhibiting expression of a target gene in a cell. The process comprises introduction of double-stranded tripartite RNAi constructs into the cells and reducing the expression of the corresponding messenger RNA in the cells. The constructs, which may be packaged in or delivered as sequestered RNAi constructs, differ from the canonical siRNA in that they comprise a tripartite structure which follows the general formula of having (1) an RNAi core (either native or abbreviated), (2) one or more terminal moieties attached to the RNAi core and optionally (3) a linker between the RNAi core and the terminal moiety.
