  • Publication number: 20240336934
    Abstract: Described herein are methods for treating a retinal degeneration in a subject, such as Leber's congenital amaurosis (LCA), retinitis pigmentosa (RP), and glaucoma. Also provided herein are methods of altering expression of one or more gene products in a cell, such as a retinal ganglion cell. Such methods may comprise utilizing a modified nuclease system, such as Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) system comprising a bidirectional HI promoter and gRNAs directed to retinal degeneration related genes, packaged in a single, compact adeno-associated virus (AAV) particle.

  • Patent number: 11766488
    Abstract: The presently disclosed subject matter provides compositions and methods comprising improvements of a CRISPR system (e.g. CRISPR associated (Cas) 9 (CRISPR-Cas9, non-Cas9 CRISPR systems). Such compositions may comprise modifications to the H1 promoter region, addition of 5?UTR modifications, different orthologous sequences of the H1 promoter, novel compact bidirectional promoter sequences with both pol II and pol III activity, addition of Kozak consensus sequences, termination sequences, addition of conditional pol II/pol III bidirectional promoter expression, addition of a donor template sequence for correcting mutations, or combinations thereof. Other aspects of the invention relate to modifications to Cas9 through post-transcriptional cell-cycle regulation fusions, engineered partial target sites such that the nuclease can bind without DNA cleavage, auto-regulation sites, and N-terminal modifications to modulate half-life.

  • Patent number: 7718684
    Abstract: A modest (2-5 fold) increase in androgen receptor (AR) mRNA is the only expression change consistently associated with developing resistance to antiandrogen therapy. Increased levels of AR confer resistance to anti-androgens by amplifying signal output from low levels of residual ligand and altering the normal response to antagonists. This invention provides cell based assays for use in the examination of new therapeutic modalities and provides for the design of novel antiandrogen compounds.
