  • Publication number: 20240132890
    Abstract: The invention relates to nucleic acid molecules for pseudouridylation of a target uridine in a target RNA in a mammalian cell, wherein the nucleic acid molecule comprises a guide region capable of forming a partially double stranded nucleic acid complex with the target RNA comprising the target uridine, wherein the partially double stranded nucleic acid complex is capable of engaging a mammalian pseudouridylation enzyme, wherein the guide region assists in positioning the target uridine in the partially double stranded nucleic acid complex for it to be converted to a pseudouridine by the mammalian pseudouridylation enzyme.
    Type: Application
    Filed: September 27, 2023

  • Patent number: 11851656
    Abstract: The invention relates to antisense oligonucleotides that are capable of bringing about specific editing of a target nucleotide (adenosine) in a target RNA sequence in a eukaryotic cell, wherein said oligonucleotide does not, in itself, form an intramolecular hairpin or stem-loop structure, and wherein said oligonucleotide comprises a non-complementary nucleotide in a position opposite to the nucleotide to be edited in the target RNA sequence.
    Type: Grant

  • Publication number: 20220127609
    Abstract: The invention relates to editing oligonucleotides (EONs) for binding to a target nucleic acid and recruiting an enzyme with nucleotide deamination activity to edit the target nucleic acid. The EONs carry phosphonoacetate internucleotide linkage modifications and/or unlocked nucleic acid (UNA) ribose modifications at specified positions and do not carry such modifications on positions that would lower nucleic acid editing efficiency. The selection of positions that should or should not carry a modification is based on computational modelling that revealed incompatibilities of the modifications with the enzyme with nucleotide deamination activity.

  • Publication number: 20210230590
    Abstract: The invention relates to editing oligonucleotides (EONs) that carry stereospecific phosphorothioate internucleotide linkage modifications at specified positions and that do not carry such modifications on positions that would lower RNA editing efficiency. The selection of positions that should or should not carry a phosphorothioate Rp and/or Sp configuration modification is based on computational modelling that revealed incompatibilities of the stereospecific linkages with the intermolecular oxygen-mediated hydrogen bond network.

  • Publication number: 20210079393
    Abstract: The invention relates to editing oligonucleotides (EONs) that carry 2?-0-methoxyethyl (2?-MOE) ribose modifications at specified positions and that do not carry such modifications on positions that would lower RNA editing efficiency. The selection of positions that should or should not carry a 2?-MOE modification is based on computational modelling that revealed steric clashes between the 2?-MOE modification and mammalian ADAR enzymes.
