Provided are compounds, methods, and pharmaceutical compositions for reducing the amount or activity of PRNP RNA in a cell or animal, and in certain instances reducing the amount of PrP 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 spongiform changes in the brain, development of abnormal protein aggregates, neuronal loss, markers of neuronal loss, rapidly progressing dementia, and death. Such neurodegenerative diseases include prion diseases, Creutzfeldt-Jakob disease (CJD), variant Creutzfeldt-Jakob Disease (vCJD), familial Creutzfeldt-Jakob Disease (fCJD), Gerstmann-Straussler-Scheinker syndrome, fatal familial insomnia, kuru, Alzheimer's disease, or Parkinson's disease.

Disclosed herein are methods for treating hereditary transthyretin-mediated amyloidosis (hATTR amyloidosis) in a human patient in need thereof by administering an effective amount of a transthyretin (TTR)-inhibiting composition.

The invention relates to iRNA, e.g., double stranded ribonucleic acid (dsRNA), compositions targeting the Serpinc1 gene, and methods of using such iRNA, e.g., dsRNA, compositions to inhibit expression of Serpinc1 and to treat subjects having a Serpinc1-associated disease, e.g., a bleeding disorder, such as a hemophilia.

This invention provides a variety of novel adeno-associated vims (AAV) vectors for gene therapy applications in the treatment of glycogen storage disease type 1a (GSD-Ia). Disclosed herein are a number of recombinant nucleic acid molecules, vectors and recombinant AAV that incorporate a modified G6PC promoter/enhancer sequence. Utilization of the modified G6PC promoter/enhancer sequence results in enhanced AAV yield and quality when expressed from various host cell platforms. Also provided herein are compositions comprising the novel AAV of the invention and methods of treating GSD-Ia using the same.

Disclosed herein is a system to recruit ADARs to catalyze therapeutic editing of point mutations via the use of engineered RNA scaffolds, engineered DNA scaffolds or DNA-RNA hybrid scaffolds. The system comprises an engineered ADAR2 guide RNA (adRNA) that bears a 20-100 bp complementarity with the target RNA and ADAR2 recruiting domain from the GluR2 mRNA at either or both the 5′ end or the 3′ end.

This invention provides compositions for use in distributing active agents for treating a malignant tumor in a subject. The compositions contain RNAi molecules targeted to a human GST-π, along with RNAi molecules targeted to a human p21, and a pharmaceutically acceptable carrier. The carrier can include nanoparticles composed of an ionizable lipid, a structural lipid, one or more stabilizer lipids, and a lipid for reducing immunogenicity of the nanoparticles. This invention further provides methods for preventing or treating a malignant tumor by administering a therapeutically effective amount of an RNAi composition.

The invention relates to double-stranded ribonucleic acid (dsRNA) compositions targeting the LECT2 gene, and methods of using such dsRNA compositions to alter (e.g., inhibit) expression of LECT2.

Methods for treating subjects who have autoimmune diseases including multiple sclerosis. The methods include administering, e.g., orally, one or more micro RNAs, e.g., miR-30d, miR-7706, and miR-1246, or mimics thereof.

Methods of treating a human subject having a disease associated with Interferon Regulatory Factor 5 (IRF5) comprise administering to the subject an antisense oligomer to an IRF 5 nucleic acid.

The present disclosure relates to methods for treating cancer in patients having low expression of MHC Class I genes, and in patients having increased serum levels of PD-L2 by administration of a TLR9 agonist.
