Abstract: The present disclosure describes improved adeno-associated virus (AAV) vectors for gene therapy applications in the treatment of glycogen storage disease, particularly glycogen storage disease type Ia (GSD-Ia). Described are recombinant nucleic acid molecules, vectors and recombinant AAV that include a G6PC promoter/enhancer, a synthetic intron, a G6PC coding sequence (such as a wild-type or codon-optimized G6PC coding sequence), and stuffer nucleic acid sequence situated between the G6PC promoter/enhancer and the intron, as well as between the intron and the G6PC coding sequence. The recombinant AAVs disclosed herein exhibit highly efficient liver transduction and are capable of correcting metabolic abnormalities in an animal model of GSD-Ia.

Abstract: The use of recombinant adeno-associated virus (AAV) virions for delivery of DNA molecules to muscle cells and tissue in the treatment of anemia is disclosed. The invention allows for the direct, in vivo injection of recombinant AAV virions into muscle tissue, e.g., by intramuscular injection, as well as for the in vitro transduction of muscle cells which can subsequently be introduced into a subject for treatment. The invention provides for sustained, high-level expression of a delivered nucleotide sequence encoding erythropoietin, and for in vivo secretion thereof from transduced muscle cells such that systemic delivery is achieved.

Abstract: The subject invention concerns materials and methods for gene therapy. One aspect of the invention pertains to vectors which can be used to effect genetic therapy in animals or humans having genetic disorders where expression of high levels of a protein of interest are required to treat or correct the disorder. The subject invention also pertains to methods for treating animals or humans in need of gene therapy to treat or correct a genetic disorder. The materials and methods of the invention can be used to provide therapeutically effective levels of a protein that is non-functional, or that is absent or deficient in the animal or human to be treated. In one embodiment, the materials and methods can be used to treat alpha-1-antitrypsin deficiency.

Abstract: Disclosed are water-soluble gel-based compositions for the delivery of recombinant adeno-associated virus (rAAV) vectors that express nucleic acid segments encoding therapeutic constructs including peptides, polypeptides, ribozymes, and catalytic RNA molecules, to selected cells and tissues of vertebrate animals. Also disclosed are gel-based rAAV compositions are useful in the treatment of mammalian, and in particular, human diseases, including for example, cardiac disease or dysfunction, and musculoskeletal disorders and congenital myopathies, including, for example, muscular dystrophy, acid maltase deficiency (Pompe's disease), and the like. In illustrative embodiments, the invention provides rAAV vectors comprised within a biocompatible gel composition for enhanced viral delivery/transfection to mammalian tissues, and in particular to vertebrate muscle tissues such as a human heart or diaphragm tissue.

Abstract: Vectors that encode Adeno-Associated Virus (AAV) Rep and Cap proteins of different serotypes and Adenovirus transcription products that provide helper functions were used to produce pseudotyped recombinant AAV (rAAV) virions. Purification methods generated pseudotyped rAAV virion stocks that were 99% pure with titers of 1×1012–1×1013 vector genomes/ml.

Abstract: Serotype 1 recombinant adeno-associated virus (rAAV) vectors were used to deliver functional acid alpha-glucosidase genes in vitro and in vivo to muscle cells deficient in acid alpha-glucosidase. The vector-treated cells overexpressed acid alpha-glucosidase. Vector-treated animals displayed restored enzymatic activity and muscle function. Serotype 1 rAAV vectors induced significantly greater acid alpha-glucosidase expression compared to serotype 2 rAAV vectors.
