  • Publication number: 20160201058
    Abstract: Efficient sequence specific gene silencing is possible through the use of siRNA technology. By selecting particular siRNAs by rational design, one can maximize the generation of an effective gene silencing reagent, as well as methods for silencing genes. Methods, compositions, and kits generated through rational design of siRNAs are disclosed including those directed to nucleotide sequences for TTR.

  • Patent number: 9353368
    Abstract: 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.

  • Patent number: 9334495
    Abstract: Compositions and methods for inhibiting the actions of non-coding RNAs such as miRNAs and piRNAs are provided. The compositions comprise single or double stranded oligonucleotides conjugated with Minor Groove Binders (“MGBs”). The oligonucleotides can vary in length, can contain nucleotides having one or more modifications, and have regions that are substantially complementary to one or more mature miRNAs or piRNAs.

  • Publication number: 20160115484
    Abstract: RNAi constructs directed to MAP4K4 that demonstrate unexpectedly high gene silencing activities, and uses thereof are disclosed. The blunt-ended constructs have a double-stranded region of 19-49 nucleotides. The constructs have selective minimal modifications to confer an optimal balance of biological activity, toxicity, stability, and target gene specificity. For example, the strands may be modified (e.g., one or both ends of the sense strand is modified by 2?-O-methyl groups), such that the construct is not cleaved by Dicer or other RNAse III, the antisense strand may also be modified by a 2?-O-methyl group at the penultimate 5?-end nucleotide to greatly reduce off-target silencing.
