摘要:
The presently disclosed subject matter provides compositions and methods for the expression of CRISPR guide RNAs using the H1 promoter. In particular, compositions and methods are provided for the use of the H1 promoter to express CRISPR guide RNA (gRNA) with altered specificity of the 5′ nucleotide, as well as use of the H1 promoter sequence as a bidirectional promoter to express Cas9 nuclease and the gRNA simultaneously. Compositions and methods are also provided for the expression and regulation of gRNA expression in vivo through the use of RNA ribozymes and regulatable aptazymes.
摘要:
Disclosed herein are methods and compositions for insertion of transgene sequences encoding proteins involved in clotting into the genome of a cell for treating conditions including hemophilias. In one aspect, described herein is a non-naturally occurring zinc-finger protein (ZFP) that binds to a target site in a region of interest (e.g., an albumin gene) in a genome, wherein the ZFP comprises one or more engineered zinc-finger binding domains. In certain embodiments, the zinc finger domain recognizes a target site in an albumin gene. In some embodiments, the zinc finger protein comprises five or six zinc finger domains designated and ordered F1 to F5 or F1 to F6, as shown in a single row of Table 1.

摘要:
The present invention provides AAV capsid proteins, virus capsids comprising said capsid proteins and virus vectors comprising said capsid proteins, wherein the AAV capsid proteins have one or more mutations, wherein the mutation(s) result in a phenotype of decreased liver transduction and/or reduced glycan binding affinity as compared to a control. The invention also provides methods of administering the virus vectors and virus capsids of the invention to a cell or to a subject.
