Up-Regulation of ENO1 by HIF-1α in Retinal Pigment Epithelial Cells after Hypoxic Challenge Is Not Involved in the Regulation of VEGF Secretion. [PDF]

open access: yesPLoS ONE, 2016
Alpha-enolase (ENO1), a major glycolytic enzyme, is reported to be over-expressed in various cancer tissues. It has been demonstrated to be regulated by the Hypoxia-inducible factor 1-α (HIF-1α), a crucial transcriptional factor implicated in tumor ...

A bio-functional polymer that prevents retinal scarring through modulation of NRF2 signalling pathway

open access: yesNature Communications, 2022
One common cause of vision loss after retinal detachment surgery is retinal scarring. Here the authors demonstrate that a bio-functional polymer can prevent retinal scarring by suppression of epithelial-mesenchymal transition and hyper-proliferation of ...

Bisretinoids of the Retina: Photo-Oxidation, Iron-Catalyzed Oxidation, and Disease Consequences

open access: yesAntioxidants, 2021
The retina and, in particular, retinal pigment epithelial cells are unusual for being encumbered by exposure to visible light, while being oxygen-rich, and also amassing photoreactive molecules.

Matrix Metalloproteinase 13 Is Associated with Age-Related Choroidal Neovascularization

open access: yesAntioxidants, 2023
Age-related macular degeneration (AMD) is a leading cause of severe vision loss in older individuals in developed countries. Despite advances in our understanding of AMD, its pathophysiology remains poorly understood.

Ginsenoside protopanaxadiol protects adult retinal pigment epithelial-19 cells from chloroquine by modulating autophagy and apoptosis

open access: yesPLoS ONE, 2022
Chloroquine often causes serious eye and vision problems, which are mainly mediated by lysosomotropic alteration. In this study, we investigated whether the ginsenoside protopanaxadiol relieves chloroquine-induced retinopathy by restoring lysosomotropic ...

Infection of Human Retinal Pigment Epithelial Cells with Dengue Virus Strains Isolated during Outbreaks in Singapore

open access: yesMicroorganisms, 2022
Prevalence of dengue retinopathy varies across epidemics, with the disease linked to circulation of dengue virus serotype 1 (DENV-1). The retinal pigment epithelium has been implicated in the pathology.

Exocytosis by Retinal Pigment Epithelial Cells

open access: yesOphthalmic Research, 2009
We observed cultured retinal pigment epithelial cells as they responded to the introduction of latex particles. The cells showed phagocytosis of particles 1 h after administration of latex and were filled with particles after 24 h. After 7 days, exocytosis of latex from basal plasma membrane was documented.

Widespread subclinical cellular changes revealed across a neural-epithelial-vascular complex in choroideremia using adaptive optics

open access: yesCommunications Biology, 2022
The in vivo pathogenesis of the blinding retinal degeneration choroideremia is visualized, which reveals enlarged and area-disrupted retinal pigment epithelial cells, providing evidence for polymegathism in choroideremia.

Preclinical Evaluation of a Cell-Based Gene Therapy Using the Sleeping Beauty Transposon System in Choroidal Neovascularization

open access: yesMolecular Therapy: Methods & Clinical Development, 2019
Age-related macular degeneration (AMD) is a progressive retinal disorder characterized by imbalanced pro- and antiangiogenic signals. The aim of this study was to evaluate the effect of ex vivo cell-based gene therapy with stable expression of human ...

Generating retinal neurons by reprogramming retinal pigment epithelial cells [PDF]

open access: yesExpert Opinion on Biological Therapy, 2010
Retinal degenerations cause blindness. One potential therapy is cell replacement. Because the human retina lacks regeneration capacity, much attention has been directed towards searching for cells that can differentiate into retinal neurons.We discuss the possibility of using transcription factor genes to channel retinal pigment epithelial (RPE) cells'
