The disclosure relates to double stranded ribonucleic acid (dsRNAi) agents and compositions targeting an ATXN2 gene, as well as methods of inhibiting expression of an ATXN2 gene and methods of treating subjects having an ATXN2-associated neurodegenerative disease or disorder, e.g., SCAs and ALS, using such dsRNAi agents and compositions.

The present invention relates to new nucleic acid molecules of therapeutic interest, in particular for use in the treatment of cancer.

The present invention is related to a ribonucleic acid comprising a double stranded structure whereby the double-stranded structure comprises a first strand and a second strand, whereby the first strand comprises a first stretch of contiguous nucleotides and whereby said first stretch is at least partially complementary to a target nucleic acid, and the second strand comprises a second stretch of contiguous nucleotides whereby said second stretch is at least partially identical to a target nucleic acid, and whereby the double stranded structure is blunt ended.

This invention pertains to modified compositions for use in CRISPR systems, and their methods of use. In particular, length-modified and chemically-modified forms of crRNA are described for use as a reconstituted guide RNA for interaction with Cas9 of CRISPR systems. The resultant length-modified and chemically-modified forms of crRNA are economical to produce and can be tailored to have unique properties relevant to their biochemical and biological activity in the context of the CRIPSR Cas9 endonuclease system.

The present invention provides bivalent molecules comprising a first oligonucleotide linked to a second oligonucleotide. The first and the second oligonucleotide are preferably linked via a linking moiety. Preferably, both the first and/or the second oligonucleotide comprise an antisense sequence complementary to a cellular RNA such as mRNA or microRNA.

The present disclosure features useful compositions and methods to treat disorders for which deamination of an adenosine in an mRNA produces a therapeutic result, e.g., in a subject in need thereof.

The instant disclosure features single-stranded RNA molecules comprising one or more internal, non-nucleotide spacers. A non-nucleotide spacer covalently links nucleotide portions of the molecule. The single-stranded RNA molecules function as guide or antisense strands that are capable of inhibiting gene expression via an RNA interference mechanism and, thus, represent single-stranded RNAi agents. The single-stranded RNAi molecules can be used in methods for a variety of therapeutic, diagnostic, target validation, genomic discovery, genetic engineering, and pharmacogenomic applications.

The present invention relates to nucleic acids, compositions and methods for the treatment of facioscapulohumeral dystrophy.

The present invention is related to a ribonucleic acid comprising a double stranded structure whereby the double-stranded structure comprises a first strand and a second strand, whereby the first strand comprises a first stretch of contiguous nucleotides and whereby said first stretch is at least partially complementary to a target nucleic acid, and the second strand comprises a second stretch of contiguous nucleotides whereby said second stretch is at least partially identical to a target nucleic acid, and whereby the double stranded structure is blunt ended.
