Methods for reversing one or more mutations in the telomerase (TERT) promoter are provided and may be used to treat a cancer. In some embodiments, programmable base editing (PBE) is used to correct a mutated TERT promoter (e.g., −124 C>T, −228C>T, or −250C>T to −124 C, −228C, or −250C, respectively) by using a single guide (sg) RNA-guided and deactivated Campylobacter jejuni Cas9-fused adenine base editor (CjABE). These methods can be used to treat a cancer, such as for example glioblastoma multiforme (GBM), in a mammalian subject in vivo.

The present disclosure provides enzyme replacement therapy using gene therapy vectors, such as adeno-associated virus (AAV) vectors expressing human Cystathionine Beta-Synthase (CBS) to reduce the amount of serum homocysteine (Hcy) and increase the amount of downstream metabolites, such as cystathionine and cysteine (Cys), which can be used for treatment of diseases, such as homocystinuria and homocysteine remethylation disorders.

Provided herein are compounds comprising peptides that bind Bfl-1. Also provided are compositions containing these peptides and methods of using such peptides in the treatment of cancer that include administering to a subject one of the peptides.

Compositions and methods for anti-oxidant therapy are provided.

The present disclosure relates to compositions and methods for modulating gene expression and in particular to DNA binding proteins and their use for increasing expression of Klotho. In some examples, the present disclosure provides an isolated or recombinant DNA binding protein comprising or attached to a transcriptional activation domain wherein the DNA binding protein binds to a target sequence within or near a Klotho gene.

The present disclosure relates to a tyrosine hydroxylase (TH) variant lacking 60 to 120 amino acid residues at the N terminus, and a pharmaceutical composition comprising the TH variant lacking 60 to 120 amino acid residues at the N terminus and the aromatic L-amino acid decarboxylase (AADC). The present disclosure further relates to a nucleotide construct, a vector plasmid, a cell or a virus comprising the TH variant or the pharmaceutical composition, as well as use of the virus in the manufacture of a medicament for treating neurodegenerative diseases (e.g., Parkinson's Disease).

The present invention provides a non-naturally occurring composition comprising a CRISPR nuclease comprising a sequence having at least 95% identity to the amino acid sequence of SEQ ID NO: 3 or a nucleic acid molecule comprising a sequence encoding the CRISPR nuclease.

To allow control over injected genetically engineered cells, it is helpful that the genetically engineered cells express a marker that can be used to detect such cells among a pool of unmodified cells. Some embodiments relate to a marked protein comprising a TCR constant domain and an exogenous amino acid variation that comprises a sequence that is detectable and identifiable within the TCR constant domain. Other embodiments relate to an antibody epitope that is attached to a TCR chain. Both the marked proteins and the antibody epitopes can be used to track genetically engineered cells.

Disclosed are chimeric antigen receptor (CAR) polypeptides comprising a CD229 antigen binding domain, a transmembrane domain, and an intracellular signaling domain. Disclosed are nucleic acid sequences capable of encoding a CAR polypeptide comprising a CD229 antigen binding domain, a transmembrane domain, and an intracellular signaling domain. Also disclosed are vectors and cells comprising one or both of the CAR polypeptides and nucleic acid sequences capable of encoding CAR polypeptides. Also disclosed are methods of treating.

Provided herein are Clostridial Botulinum neurotoxin (BoNT) polypeptides of a novel serotype (BoNT/X) and methods of making and using the BoNT polypeptides, e.g., in therapeutic applications.
