Age-associated changes in electroretinography measures in companion dogs

Salzman, M. M., Merten, N., Panek, W. K., Fefer, G., Mondino, A., Westermeyer, H. D., … Mowat, F. M. (2023, June 11). DOCUMENTA OPHTHALMOLOGICA, Vol. 6.

author keywords: Translational model; Aging; Retina; ERG; Canine; Anxiolytic

author keywords: Leber congenital amaurosis; RPE65; Canine model; Briard; Gene therapy; Gene augmentation; AAV2; Immune response; Repeated injection; Subretinal injection
MeSH headings : Animals; Carrier Proteins / genetics; Clinical Trials, Phase I as Topic / methods; Clinical Trials, Phase II as Topic / methods; Disease Models, Animal; Dogs; Eye Proteins / genetics; Genetic Therapy / methods; Humans; Leber Congenital Amaurosis / genetics; Leber Congenital Amaurosis / immunology; Leber Congenital Amaurosis / therapy; cis-trans-Isomerases
TL;DR: Dogs with a spontaneous mutation in Rpe65 have been key in the testing of gene augmentation therapy using viral vectors to introduce a normal copy of the Rpe55 gene, leading to human clinical trials for treatment of Leber congenital amaurosis type II. (via Semantic Scholar)

RPE65 gene therapy slows cone loss in Rpe65-deficient dogs

Gene Therapy, 20(5), 545–555.

By: F. Mowat*, A. Breuwer*, J. Bartoe*, M. Annear*, Z. Zhang*, A. Smith*, J. Bainbridge*, S. Petersen-Jones*, R. Ali*

author keywords: rAAV2; leber congenital amaurosis; RPE65; canine model; cone photoreceptors
MeSH headings : Animals; Cell Survival / genetics; Disease Models, Animal; Dogs; Genetic Therapy; Leber Congenital Amaurosis / genetics; Leber Congenital Amaurosis / pathology; Leber Congenital Amaurosis / therapy; Retina / drug effects; Retina / pathology; Retinal Cone Photoreceptor Cells / drug effects; Retinal Cone Photoreceptor Cells / pathology; Retinal Rod Photoreceptor Cells / drug effects; Retinal Rod Photoreceptor Cells / pathology; cis-trans-Isomerases / administration & dosage; cis-trans-Isomerases / deficiency; cis-trans-Isomerases / genetics
TL;DR: The results suggest that gene therapy may be able to slow cone degeneration in patients if intervention is sufficiently early and also that it is probably important to treat the macula in order to preserve central function. (via Semantic Scholar)

Von Hippel-Lindau protein in the RPE is essential for normal ocular growth and vascular development

Development, 139(13), 2340–2350.

By: C. Lange*, U. Luhmann*, F. Mowat*, A. Georgiadis*, E. West*, S. Abrahams, H. Sayed*, M. Powner* ...

author keywords: Von Hippel-Lindau factor; Hypoxia-inducible factor 1; Microphthalmia; Angiogenesis; Mouse
MeSH headings : Animals; Aniridia / genetics; Aniridia / pathology; Apoptosis / genetics; Basic Helix-Loop-Helix Transcription Factors / analysis; Cell Proliferation; Electroretinography; Erythropoietin / metabolism; Eye / blood supply; Eye / cytology; Eye / growth & development; Gene Deletion; Hypoxia-Inducible Factor 1, alpha Subunit / physiology; Immunohistochemistry; Mice; Mice, Inbred C57BL; Mice, Transgenic; Microphthalmos / genetics; Microphthalmos / pathology; Retinal Pigment Epithelium / cytology; Retinal Pigment Epithelium / growth & development; Vascular Endothelial Growth Factor A / analysis; Von Hippel-Lindau Tumor Suppressor Protein / genetics; Von Hippel-Lindau Tumor Suppressor Protein / physiology
TL;DR: Vhl-dependent regulation of Hif1a in the RPE is essential for normal RPE and iris development, ocular growth and vascular development in the anterior chamber, whereas Vhl- dependent regulation of other downstream pathways is crucial for normal development and maintenance of the retinal vasculature.

HIF-1alpha and HIF-2alpha Are Differentially Activated in Distinct Cell Populations in Retinal Ischaemia

PLoS ONE, 5(6), e11103.

By: F. Mowat*, U. Luhmann*, A. Smith*, C. Lange*, Y. Duran*, S. Harten*, D. Shukla*, P. Maxwell*, R. Ali*, J. Bainbridge*

Ed(s): K. Koch

MeSH headings : Animals; Basic Helix-Loop-Helix Transcription Factors / metabolism; Blotting, Western; Enzyme-Linked Immunosorbent Assay; Erythropoietin / metabolism; Hypoxia-Inducible Factor 1, alpha Subunit / metabolism; Immunohistochemistry; Ischemia / metabolism; Mice; Retinal Vessels / metabolism; Vascular Endothelial Growth Factor A / metabolism
TL;DR: The findings suggest that HIF-2alpha activation plays a key role in regulating the response of Müller glia to hypoxia, consistent with differential roles in retinal ischaemia. (via Semantic Scholar)
