Leber's congenital amaurosis (LCA) is a group of inherited blinding diseases with onset during childhood. One form of the disease, LCA2, is caused by mutations in the retinal pigment epithelium-specific 65-kDa protein gene (RPE65). We investigated the safety of subretinal delivery of a recombinant adeno-associated virus (AAV) carrying RPE65 complementary(More)
The safety and efficacy of gene therapy for inherited retinal diseases is being tested in humans affected with Leber's congenital amaurosis (LCA), an autosomal recessive blinding disease. Three independent studies have provided evidence that the subretinal administration of adeno-associated viral (AAV) vectors encoding RPE65 in patients affected with LCA2(More)
The short- and long-term effects of gene therapy using AAV-mediated RPE65 transfer to canine retinal pigment epithelium were investigated in dogs affected with disease caused by RPE65 deficiency. Results with AAV 2/2, 2/1, and 2/5 vector pseudotypes, human or canine RPE65 cDNA, and constitutive or tissue-specific promoters were similar. Subretinally(More)
We evaluated the safety and efficacy of an optimized adeno-associated virus (AAV; AAV2.RPE65) in animal models of the RPE65 form of Leber congenital amaurosis (LCA). Protein expression was optimized by addition of a modified Kozak sequence at the translational start site of hRPE65. Modifications in AAV production and delivery included use of a long stuffer(More)
Alveolar rhabdomyosarcomas are pediatric solid tumors with a hallmark cytogenetic abnormality: translocation of chromosomes 2 and 13 [t(2;13) (q35;q14)]. The genes on each chromosome involved in this translocation have been identified as the transcription factor-encoding genes PAX3 and FKHR. The NH2-terminal paired box and homeodomain DNA-binding domains of(More)
The t(2;13) and t(1;13) translocations of alveolar rhabdomyosarcoma (ARMS) result in chimeric PAX3-FKHR or PAX7-FKHR transcription factors, respectively. In each chimera, a PAX DNA-binding domain is fused to the C-terminal FKHR transactivation domain. Previously we demonstrated that PAX3-FKHR is more potent than PAX3 because the FKHR transactivation domain(More)
BACKGROUND Gene therapy has the potential to reverse disease or prevent further deterioration of vision in patients with incurable inherited retinal degeneration. We therefore did a phase 1 trial to assess the effect of gene therapy on retinal and visual function in children and adults with Leber's congenital amaurosis. METHODS We assessed the retinal and(More)
Normal melanocytes and melanocytes of normal nevi, primary melanoma in the radial (RGP) and vertical (VGP) growth phases, and metastatic melanoma exhibited and maintained phenotypic differences when grown in tissue culture or in experimental animals. Only metastatic and VGP primary melanoma cells were tumorigenic in athymic nude mice and had nonrandom(More)
Three primary and 16 metastatic melanoma cell lines were established from primary and metastatic lesions of 4 patients with malignant melanoma. Comparison of metastatic melanoma cells with cells of the vertical growth phase (VGP) or late primary melanoma from the same individual revealed, generally, a shorter population-doubling time, growth to a higher(More)
PAX3 and PAX7 are closely related paired box family members expressed during early neural and myogenic development. Assay of PAX3 and PAX7 mRNA expression in embryonal rhabdomyosarcoma, neuroblastoma, Ewing's sarcoma, and melanoma cell lines revealed tumor-specific expression patterns similar to the corresponding embryonic lineages. Although the mammalian(More)
