A high therapeutic index is as important for gene-based therapies as it is for chemotherapy or radiotherapy. One approach has been transcriptional targeting through the use of tissue-specific regulatory elements. A more versatile approach would be to use a regulatory element that is controlled via a parameter common to a broad range of diseases. Ischemia is(More)
We evaluated the efficacy of equine infectious anaemia virus (EIAV)-based lentiviral vectors encoding endostatin (EIAV.endostatin) or angiostatin (EIAV.angiostatin) in inhibiting angiogenesis and vascular hyperpermeability in the laser-induced model of choroidal neovascularisation (CNV). Equine infectious anaemia virus.endostatin, EIAV.angiostatin or(More)
Autosomal recessive Stargardt disease (STGD1) is a macular dystrophy caused by mutations in the ABCA4 (ABCR) gene. The disease phenotype that is most recognized in STGD1 patients, and also in the Abca4-/- mouse (a disease model), is lipofuscin accumulation in retinal pigment epithelium. Here, we tested whether delivery of the normal (wt) human ABCA4 gene to(More)
Anemia is a common clinical problem, and there is much interest in its role in promoting left ventricular hypertrophy through increasing cardiac workload. Normally, red blood cell production is adjusted through the regulation of erythropoietin (Epo) production by the kidney. One important cause of anemia is relative deficiency of Epo, which occurs in most(More)
The use of activated macrophages in the treatment of cancer has been largely ineffectual. By 'arming' these cells with the ability to express a therapeutic gene we demonstrate significant advances in the efficacy of this approach. We have used a hypoxia-regulated adenoviral vector to transduce human macrophages with either a reporter or a therapeutic gene(More)
BACKGROUND We have developed minimal non-primate lentiviral vectors based on the equine infectious anaemia virus (EIAV). We evaluated the in vivo expression profiles of these vectors delivered regionally to ocular tissues to define their potential utility in ocular gene therapy. METHODS EIAV vectors pseudotyped with VSV-G or rabies-G envelope proteins(More)
Usher syndrome type 1B is a combined deaf-blindness condition caused by mutations in the MYO7A gene. Loss of functional myosin VIIa in the retinal pigment epithelia (RPE) and/or photoreceptors leads to blindness. We evaluated the impact of subretinally delivered UshStat, a recombinant EIAV-based lentiviral vector expressing human MYO7A, on photoreceptor(More)
PURPOSE StarGen is an equine infectious anemia virus (EIAV)-based lentiviral vector that expresses the photoreceptor-specific adenosine triphosphate (ATP)-binding cassette transporter (ABCA4) protein that is mutated in Stargardt disease (STGD1), a juvenile macular dystrophy. EIAV vectors are able to efficiently transduce rod and cone photoreceptors in(More)
Recombinant adenoviral vectors have a number of advantages for gene therapy, including transduction of a range of dividing and non-dividing cell types. However, this broad range may be a disadvantage if non-target cells are transduced and are adversely affected by expression of the transferred gene. Here we describe a novel adenoviral vector in which(More)
Hypoxia is a common physiological feature of tumours. It activates a signalling cascade that culminates in the stabilization of the HIF-1 transcription factor and activation of genes that possess a hypoxia response element (HRE). We have used an optimized hypoxia responsive promoter (OBHRE) to investigate hypoxia-targeted gene expression in vivo in the(More)
