In one aspect, described herein is a recognition element for splicing modifier (REMS) that can be recognized by a compound provided herein. In another aspect, described herein are methods for modulating the amount of a product of a gene, wherein a precursor RNA transcript transcribed from the gene contains a REMS, and the methods utilizing a compound described herein. More particularly, described herein are methods for modulating the amount of an RNA transcript or protein product encoded by a gene, wherein a precursor RNA transcript transcribed from the gene comprises a REMS, and the methods utilizing a compound described herein. In another aspect, provided herein are artificial gene constructs comprising a REMS, and uses of those artificial gene constructs to modulate functional protein production. In another aspect, provided herein are methods for altering endogenous genes to comprise a REMS, and the use of a compound described herein to modulate the functional protein produced from such altered endogenous genes.

Provided herein are compositions and methods for treating succinic semialdehyde dehydrogenase deficiency (SSADHD). Compositions may include a gene encoding a functional succinic semialdehyde dehydrogenase (SSADH) enzyme, such as ALDH5A1, operably linked to a targeting vector. The functional SSADII enzyme is envisioned to lower the levels of circulating gamma-hydroxybutyric acid (GHB) and γ-aminobutyric acid (GABA). In some embodiments, combination therapies are envisioned, comprising administering to the subject therapeutically effective amounts of a combination of a composition comprising a gene encoding a functional SSADII enzyme operably linked to a targeting vector; one or more mTOR inhibitors; and a GABA-T inhibitor. Suitable mTOR inhibitors include rapamycin, while suitable GABA-T inhibitors include vigabatrin.

The present invention relates to a gene delivery complex comprising: a biocompatible polymer backbone; and pegylated lactoferrin connected to the biocompatible polymer backbone by means of a covalent bond. The gene delivery complex is orally administered into an individual, can be absorbed in vivo by means of a lactoferrin receptor, and enables the in vivo delivery of a target gene and the expression thereof.

The present invention relates to a nucleic acid expression cassette, in particular for the expression of a human liver-specific and/or liver-expressed protein and/or preferably physiologically active domains and/or fragments thereof in a patient suffering from a monogenetic disorder caused by a mutation in the gene coding for the liver-specific and/or liver-expressed protein.

Provided herein are methods, systems, and related vectors and compositions allowing for noninvasive control of neural circuits. In particular, the methods and systems herein described utilize acoustically targeted chemogenetics to achieve a noninvasive neuromodulation in specifically selected cell-types among spatially selected brain regions.

Provided herein are compositions and methods of using base editors comprising a polynucleotide programmable nucleotide binding domain and a nucleobase editing domain in conjunction with a guide polynucleotide. Also provided herein are base editor systems for editing nucleobases of target nucleotide sequences.
