Provided are compounds, methods, and pharmaceutical compositions for reducing the amount or activity of APP RNA in a cell or animal, and in certain instances reducing the amount of APP protein in a cell or animal. Such compounds, methods, and pharmaceutical compositions are useful to ameliorate at least one symptom or hallmark of a neurodegenerative disease or disorder. Such symptoms and hallmarks include cognitive impairment, including a decline in memory and language skills, behavioral and psychological symptoms such as apathy and lack of motivation, gait disturbances and seizures, progressive dementia, and abnormal amyloid deposits.

The present invention aims at establishing a novel therapy for facioscapulohumeral muscular dystrophy.

An oligonucleotide or a pharmaceutically acceptable salt thereof, wherein the oligonucleotide comprises an oligonucleotide of 15-30 bases consisting of a nucleotide sequence complementary to the region of nucleotide Nos. 502-556 or 578-612 of DUX4-fl mRNA consisting of the nucleotide sequence as shown in SEQ ID NO: 1; the 5′ and/or 3′ end of the oligonucleotide may be chemically modified; and the oligonucleotide is capable of switching the splice form of the DUX4 gene from DUX4-fl to DUX4-s. A pharmaceutical drug comprising the above oligonucleotide or a pharmaceutically acceptable salt thereof (e.g. therapeutic for facioscapulohumeral muscular dystrophy).

Provided are compounds, methods, and pharmaceutical compositions for reducing the amount or activity of ATXN3 mRNA in a cell or animal, and in certain instances reducing the amount of Ataxin-3 protein in a cell or animal. Such compounds, methods, and pharmaceutical compositions are useful to prevent or ameliorate at least one symptom or hallmark of a neurodegenerative disease. Such symptoms and hallmarks include ataxia, neuropathy, and aggregate formation. Such neurodegenerative diseases include SCA3.

The present embodiments provide methods, compounds, and compositions useful for inhibiting DGAT2 expression, which may be useful for treating, preventing, or ameliorating a disease associated with DGAT2.

Disclosed are methods for modulating splicing of Ataxin 3 mRNA in an animal with modified oligonucleotides. Such compounds and methods are useful to treat, prevent, or ameliorate spinocerebellar ataxia type 3 (SCA3) in an individual in need thereof.

The present disclosure provides antisense oligonucleotides that bind to a splice modulatory element target region in an SLC6A1 RNA transcript. The present disclosure provides antisense oligonucleotides that increase the expression of a functional protein encoded by the SLC6A1 RNA transcript in a cell (i.e., GABA Transporter 1, GAT-1). The present disclosure also provides methods of treating a disease or disorder associated with non-productive SLC6A1 RNA transcripts.

In certain embodiments, the present disclosure provides methods comprising contacting a cell with a compound comprising a modified oligonucleotide complementary to a nucleic acid transcript. In certain such embodiments, the modified oligonucleotide does not interact or interacts poorly with a mRNP complex or granule. In certain such embodiments the modifications and/or motifs of the modified oligonucleotide do not promote interaction with a mRNP complex or granule. In certain embodiments, the present disclosure provides methods comprising contacting a cell with a compound comprising a modified oligonucleotide thereby reducing the size or amount of protein aggregation in the cell. In certain such embodiments, the protein aggregate is a mRNP granule. In certain such embodiments, the modifications and/or motifs of the modified oligonucleotide promote interaction with a protein aggregate, such as a mRNP granule, that results in disruption of the protein aggregate.

Disclosed is a method of treating a subject who has a neurological disease. The neurological disease may be associated with altered C9ORF72 protein activity. In one aspect, the method includes a step of administering an effective dose of a PIKFYVE antisense or inhibitory nucleic acid to a subject in need thereof, thereby rescuing the defects associated with altered C9ORF72 protein activity and/or inhibiting the expression of PIKFYVE gene.

Disclosed herein are antisense compounds and methods for decreasing PKK mRNA and protein expression. Such methods, compounds, and compositions are useful to treat, prevent, or ameliorate PKK-associated diseases, disorders, and conditions.

Described herein are aptamers capable of binding to human complement component 3 (C3) protein; compositions comprising a C3 binding aptamer with a C3-Protein; and methods of making and using the same.
