US Patent 11274300 Oligonucleotide complexes for use in RNA editing

The invention relates to double stranded oligonucleotide complexes comprising an antisense oligonucleotide (AON) and a complementary sense oligonucleotide (SON), for use in the deamination of a target adenosine in a sense target RNA sequence in a cell by an ADAR enzyme, wherein at least the nucleotide in the AON that is directly opposite the target adenosine in the target RNA sequence does not have a 2′-O-alkyl modification and the SON comprises nucleotides that are at least complementary to all nucleotides in the AON that do not have a 2′-O-alkyl modification. The invention further relates to methods of RNA editing using the AON/SON complexes of the invention.
