The present invention relates to antisense oligonucleotides that are capable of modulating expression of PIAS4 in a target cell. The antisense oligonucleotides hybridize to PIAS4 pre-mRNA. The present invention further relates to conjugates of the oligonucleotide and pharmaceutical compositions and methods for treatment of cancers such as pancreatic cancer, breast cancer and liver fibrosis using the antisense oligonucleotide.

Provided herein are improved delivery systems for oligonucleotides, said delivery system comprising a liposome that comprises neutral phospholipids and a P-ethoxy oligonucleotide, which targets a BCL2-encoding polynucleotide. Methods of treating patients with said delivery systems are also provided.

Oligonucleotides comprising modifications at the 2 and/or 3′ positions(s) along with methods of making and use against Alzheimer disease and other tauopathies are disclosed.

Provided herein are improved delivery systems for oligonucleotides, said delivery system comprising a liposome that comprises neutral phospholipids and a P-ethoxy oligonucleotide, which targets an IGF-1R-encoding polynucleotide. Methods of treating patients with said delivery systems are also provided.

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 invention relates to polynucleotide agents targeting an hydroxyacid oxidase (HAO1) gene, and methods of using such polynucleotide agents to inhibit expression of HAO1 and to treat subjects having an HAO1-associated disease, e.g., hyperoxaluria.

Provided are compounds, methods, and pharmaceutical compositions for reducing the amount or activity of FXI RNA in a cell or subject, and in certain instances reducing the amount of FXI protein in a cell or subject. Such compounds, methods, and pharmaceutical compositions are useful to prevent, treat, or ameliorate at least one symptom of a thromboembolic condition without a significant increase in a bleeding risk. Such thromboembolic conditions include deep vein thrombosis, venous or arterial thrombosis, pulmonary embolism, myocardial infarction, stroke, thrombosis associated with chronic kidney disease or end-stage renal disease (ESRD), including thrombosis associated with dialysis, or other procoagulant condition. Such symptoms include decreased blood flow through an affected vessel, death of tissue, and death.

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 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.

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.
