  • Patent number: 10633654
    Abstract: The invention related 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 preferable 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 it/are modified by four 2?—O-mehtyl 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 enhance target specificity.
