The present invention relates to antisense oligonucleotides (oligomers) that are complementary to HTRA1, leading to modulation of the expression of HTRA1. Modulation of HTRA1 expression is beneficial for a range of medical disorders, such as macular degeneration, e.g. age-related macular degeneration.

Compounds, compositions and methods are provided for modulating the expression and function of small non-coding RNAs. The compositions comprise oligomeric compounds, targeted to small non-coding RNAs. Methods of using these compounds for modulation of small non-coding RNAs as well as downstream targets of these RNAs and for diagnosis and treatment of disease associated with small non-coding RNAs are also provided.

The present disclosure provides oligomeric compounds. The present disclosure provides metabolically stable linkers that do not rapidly degrade in vivo. In certain embodiments, the present disclosure provides metabolically stable linkers for use in attaching a conjugate group to an oligonucleotide.

In certain embodiments, the present disclosure provides compounds and methods of increasing the amount or activity of a target protein in a cell. In certain embodiments, the compounds comprise a translation suppression element inhibitor. In certain embodiments, the translation suppression element inhibitor is a uORF inhibitor. In certain embodiments, the uORF inhibitor is an antisense compound.

Compositions and methods are provided for genome modification of a target sequence in the genome of a plant or plant cell. The methods and compositions employ a guide RNA/Cas endonuclease system to provide an effective system for modifying or altering target sites within the genome of a plant, plant cell or seed. Also provided are compositions and methods employing a guide polynucleotide/Cas endonuclease system for genome modification of a nucleotide sequence in the genome of a cell or organism, for gene editing, and/or for inserting or deleting a polynucleotide of interest into or from the genome of a cell or organism. Once a genomic target site is identified, a variety of methods can be employed to further modify the target sites such that they contain a variety of polynucleotides of interest. Breeding methods and methods for selecting plants utilizing a two component RNA guide and Cas endonuclease system are also disclosed. Compositions and methods are also provided for editing a nucleotide sequence in the genome of a cell.

Provided are compounds, methods, and pharmaceutical compositions for reducing the amount or activity of ATXN3 RNA in a cell or animal, and in certain embodiments reducing the amount of ATXN3 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. Such symptoms and hallmarks include motor dysfunction, aggregation formation, and neuron death. Such neurodegenerative diseases include spinocerebellar ataxia type 3 (SCA3).

The present invention provides oligomeric compounds. Certain such oligomeric compounds are useful for hybridizing to a complementary nucleic acid, including but not limited, to nucleic acids in a cell. In certain embodiments, hybridization results in modulation of the amount, activity, or expression of the target nucleic acid in a cell. In certain embodiments, hybridization results in selective modulation of the amount, activity, or expression of a target Huntingtin gene or Huntingtin transcript in a cell.

Provided are compounds, methods, and pharmaceutical compositions for reducing the amount or activity of MSH3 RNA in a cell or subject, and in certain instances reducing the amount of MSH3 protein in a cell or subject. These compounds, methods, and pharmaceutical compositions are useful to ameliorate at least one symptom or hallmark of a repeat expansion disease. Such symptoms and hallmarks include brain atrophy, muscle atrophy, nerve degeneration, uncontrolled movement, seizure, tremors, muscle weakness, muscle cramping, difficulty swallowing, difficulty speaking, decreased memory, decreased cognition, anxiety, and depression. Non-limiting examples of repeat expansion diseases that benefit from these compounds, methods, and pharmaceutical compositions are myotonic dystrophy (DM1 and DM2), amyotrophic lateral sclerosis, frontotemporal dementia, Huntington's disease, various polyglutamine disorders, Friedrich's ataxia, Fragile X syndrome, or spinocerebellar ataxia (e.g., SCA1, SCA2, SCA3, SCA6, SCAT, SCA8, SCA10, or SCA17).

The present disclosure relates to extracellular vesicles, e.g., exosomes, comprising an antisense oligonucleotide (ASO), wherein the ASO comprises a contiguous nucleotide sequence of 10 to 30 nucleotides in length that is complementary to a nucleic acid sequence within a CEBP/transcript. Also provided herein are methods for producing the exosomes and methods for using the exosomes to treat and/or prevent diseases or disorders.

Disclosed herein are IL-34 inhibitors, including IL-34 antisense oligonucleotide sequences, and methods for treating inflammatory diseases, such as an inflammatory bowel disease, and/or fibrosis, associated with elevated activity or expression of IL-34. Also disclosed are pharmaceutical compositions containing an IL-34 inhibitor, for example, a IL-34 antisense oligonucleotide, useful for treating inflammatory diseases and/or fibrosis and manufacture of medicaments containing a disclosed IL-34 inhibitor to be used in treating inflammatory diseases and/or fibrosis.
