Disclosed herein are methods and compositions for gene therapy, in particular, methods and compositions related to alterations in a capsid protein sequence for altering permissiveness of a promoter within a cell when the promoter and the capsid protein are present within the cell and the capsid protein and the promoter are in the context of a recombinant adeno-associated virus (AAV) particle.

Provided nucleic acid-based expression construct for the target cell-specific production of a therapeutic protein, such as a pro-apoptotic protein, within a target cell, including a target cell that is associated with aging, disease, or other condition, in particular a target cell that is a senescent cell or a cancer cell. Also provided are formulations and systems, including fusogenic lipid nanoparticle (LNP) formulations and systems, for the delivery of nucleic acid-based expression constructs as well as methods for making and using such nucleic acid-based expression constructs, formulations, and systems for reducing, preventing, and/or eliminating the growth and/or survival of a cell, such as a senescent cell and/or a cancer cell, which is associated with aging, disease, or other condition as well as methods for the treatment of aging, disease, or other conditions by the in vivo administration of a formulation, such as a fusogenic LPN formulation, comprising an expression construct for the target cell-specific production of a therapeutic protein, such as a pro-apoptotic protein, in a target cell that is associated with aging, disease, or other condition, in particular a target cell that is a senescent cell or a cancer cell.

A DNA plasmid useful for diagnostic and therapeutic gene therapy is disclosed. Improvements to gene therapy methods known in the art are provided to ensure cancer-targeting, high efficacy, and long durability of expression. The DNA plasmid is combined with compositions of polymeric nanoparticles for non-viral gene therapy to treat cancer, including hepatocellular carcinoma and prostate cancer.

The present invention provides a novel fusion polypeptide containing a catalytic domain of NPP1 fused to a targeting moiety, nucleic acids encoding the fusion polypeptide, a vector containing the nucleic acid integrated thereinto, a host cell transformed with the vector and pharmaceutical compositions comprising the fusion polypeptide.

The disclosure features compositions and methods for the treatment of sensorineural hearing loss and auditory neuropathy, particularly forms of the disease that are associated with mutations in otoferlin (OTOF), by way of OTOF gene therapy. The disclosure provides a variety of compositions that include a first nucleic acid vector that contains a polynucleotide encoding an N-terminal portion of an OTOF protein and a second nucleic acid vector that contains a polynucleotide encoding a C-terminal portion of an OTOF protein. These vectors can be used to increase the expression of OTOF in a subject, such as a human subject suffering from sensorineural hearing loss.

The disclosure relates to compositions and methods for rAAV-mediated delivery of a transgene to a subject. In some embodiments, the rAAV transduces the prostate tissue of a subject. In some embodiments, the methods are useful for treatment of prostate disease (e.g., prostatitis, BPH, prostate cancer).

Provided herein are compositions and methods for selective expression of a transgene. Compositions and methods for selective expression of a transgene comprise one or more human regulatory elements, which, when operably linked to a transgene, can facilitate selective expression of a transgene (for example, cell-type selective expression) in a target cell as compared to at least one or more non-target cells.

The present invention relates to compositions and methods for the preparation, manufacture and therapeutic use of polynucleotides comprising at least one terminal modification. Described herein are polynucleotides comprising at least one terminal modification, methods, processes, kits and devices using the polynucleotides comprising at least one terminal modification in one or more untranslate regions. Such untranslated regions may be a 5′ or 3′ untranslated region.

Synthetic regulation of gene expression is provided. In some embodiments, synthetic regulatory constructs are provided. In some embodiments, a synthetic regulatory construct expresses a heterologous gene in a selected cell type. In some embodiments, methods of expressing a heterologous gene in a selected cell type are provided.
