PURPOSE We evaluated adeno-associated virus (AAV)-mediated gene transfer of basic fibroblast growth factor (FGF-2) as a therapy for photoreceptor degeneration in a transgenic rat model of retinitis pigmentosa. METHODS Recombinant adeno-associated virus vector (rAAV) incorporating a constitutive cytomegalovirus (CMV) promoter was used to transfer the bovine FGF-2 gene to photoreceptors. AAV wa...
Gene therapy is an experimental treatment being investigated to correct defective genes that are responsible for disease development. To treat cancer and genetic illnesses, researchers looking into a variety of gene techniques. Finding proper vector transfer DNA tissues one the most difficult aspects therapy. Some vectors have issues with infecting both quiescent dividing cells, provoking immun...
Scalable and efficient production of high-quality recombinant adeno-associated virus (rAAV) for gene therapy remains a challenge despite recent clinical successes. We developed a new strategy for scalable and efficient rAAV production by sequestering the AAV helper genes and the rAAV vector DNA in two different subcellular compartments, made possible by using cytoplasmic vaccinia virus as a car...
Adeno-associated virus (AAV) has been widely used as a viral vector to deliver genes to animal and human tissues in gene therapy studies. Both AAV-2 and AAV-3 use cell surface heparan sulfate (HS), a highly sulfated polysaccharide, as a receptor to establish infections. In this study, we used atomic force microscopy (AFM) to investigate the interaction of HS and AAV. A silicon chip functionaliz...
Recombinant adeno-associated virus (AAV) type 2 has attracted attention because it appears to have the potential to serve as a vector for human gene therapy. An interesting feature of wild-type AAV is its site-specific integration into AAVS1, a defined locus on chromosome 19. This reaction requires the presence of two viral elements: inverted terminal repeats and Rep78/68. Accordingly, current ...
Muscle represents an attractive target tissue for adeno-associated virus (AAV) vector-mediated gene transfer for hemophilia B (HB). Experience with direct intramuscular (i.m.) administration of AAV vectors in humans showed that the approach is safe but fails to achieve therapeutic efficacy. Here, we present a careful evaluation of the safety profile (vector, transgene, and administration proced...
We examined the feasibility of using adeno-associated virus (AAV)mediated systemic delivery of endostatin in gene therapy to treat metastasis of pancreatic cancer. We established an animal model of orthotopic metastatic pancreatic cancer in which the pancreatic cancer cell line PGHAM-1 was inoculated into the pancreas of Syrian golden hamsters. Transplanted cells proliferated rapidly and metast...
It is challenging to genetically manipulate fat in adults. We demonstrate that intraperitoneal (i.p.) injection of an engineered adeno-associated virus (AAV) serotype Rec2 leads to high transduction of multiple visceral fat depots at a dose of 1 to 2 orders lower than commonly used doses for systemic gene delivery. To target adipose tissue, we develop a single AAV vector harboring two expressio...
Adeno-associated virus (AAV) is one of the most promising viral gene transfer vectors that has been shown to effect long-term gene expression and disease correction with low toxicity in animal models, and is well tolerated in human clinical trials. The surface of the AAV capsid is an essential component that is involved in cell binding, internalization, and trafficking within the targeted cell....
