The present disclosure provides oligomeric compounds comprising at least one --constrained nucleic acid as provided herein. More particularly, the --constrained nucleic acid provided herein comprise an optionally modified nucleoside with a phosphorus containing constrained internucleoside linkage such as for example a cyclic phosphate internucleoside linkage. The --constrained nucleic acid provided herein are expected to be useful for enhancing one or more properties of oligomeric compounds they are incorporated into such as for example nuclease resistance. In certain embodiments, the oligomeric compounds provided herein hybridize to a portion of a target RNA resulting in loss of normal function of the target RNA.

Certain embodiments are directed to methods and compounds for inhibiting SMN-NAT, the natural antisense transcript of SMN. Such methods and compounds are useful for increasing expression of SMN in cells and animals.

Among other things, the present disclosure provides oligonucleotides, compositions, and methods thereof. Among other things, the present disclosure encompasses the recognition that structural elements of oligonucleotides, such as base sequence, chemical modifications (e.g., modifications of sugar, base, and/or internucleotidic linkages) or patterns thereof, conjugation with additional chemical moieties, and/or stereochemistry [e.g., stereochemistry of backbone chiral centers (chiral internucleotidic linkages)], and/or patterns thereof, can have significant impact on oligonucleotide properties and activities, e.g., knockdown ability, stability, delivery, etc. In some embodiments, the oligonucleotides decrease the expression, activity and/or level of a C9orf72 gene, including but not limited to, one comprising a repeat expansion, or a gene product thereof. In some embodiments, the present disclosure provides methods for treatment of diseases using provided oligonucleotide compositions, for example, in treatment of C9orf72-related disorders.

Provided herein are methods, compounds, and compositions for reducing expression of huntingtin mRNA and protein in an animal. Such methods, compounds, and compositions are useful to treat, prevent, delay, or ameliorate Huntington's disease, or a symptom thereof.

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

The present invention relates to RNAi agents, e.g., double stranded RNA (dsRNA) agents, targeting the HMGB 1 gene. The invention also relates to methods of using such RNAi agents to inhibit expression of a HMGB1 gene and to methods of N preventing and treating an HMGB1-associated disorder, e.g., metabolic disorder or non-alcholic fatty liver disease, e.g., non-alcoholic steatohepatitis (NASH).

Provided herein are methods, compounds, and compositions for reducing expression of huntingtin mRNA and protein in an animal. Such methods, compounds, and compositions are useful to treat, prevent, delay, or ameliorate Huntington's disease, or a symptom thereof.

The present embodiments provide compounds and methods for targeting cells expressing GLP-1 receptor.

Provided are compounds, methods, and pharmaceutical compositions for reducing the amount or activity of Tau mRNA in a cell or animal, and in certain instances reducing the amount of Tau protein in a cell or animal. Such compounds, methods, and pharmaceutical compositions are useful to ameliorate at least one symptom of a neurodegenerative disease. Such symptoms include loss of memory, loss of motor function, and increase in the number and/or volume of neurofibrillary inclusions. Such neurodegenerative diseases include tauopathies, Alzheimer's Disease, Fronto-temporal Dementia (FTD), FTDP-17, Progressive Supranuclear Palsy (PSP), Chronic Traumatic Encephalopathy (CTE), Corticobasal Ganglionic Degeneration (CBD), Epilepsy, and Dravet's Syndrome.

This invention relates to compounds, compositions, and methods useful for reducing AT3 target RNA and protein levels via use of dsRNAs, e.g., Dicer substrate siRNA (DsiRNA) agents.
