Electrical estimulation of retinal pigment epithelial cells

Experimental Eye Research, 2010
We investigated and characterized the effect of externally applied electric fields (EF) on retinal pigment epithelial (RPE) cells by exposing primary cultures of human RPE cells (hRPE) and those from the ARPE19 immortalized cell line to various strengths of EF (EF-treated cells) or to no EF (control cells) under different conditions including presence ...

Early stages of retinal development depend on Sec13 function [PDF]

, 2013
ER-to-Golgi transport of proteins destined for the extracellular space or intracellular compartments depends on the COPII vesicle coat and is constitutive in all translationally active cells.

Retinal Pigment Epithelial Cells Produce Fibronectin

Ophthalmic Research, 2009
Antichick fibronectin antiserum, noncross-reactive to bovine fibronectin, was prepared to determine the production of fibronectin by cultured chick retinal pigment epithelial cells which were grown in the presence of fetal bovine serum. The typical fibrillary net pattern of fibronectin was observed by an indirect immunofluorescent technique when this ...

Hydrogen peroxide enhances transforming growth factor beta-2 induced epithelial–mesenchymal transition of ARPE-19 cells

Beni-Suef University Journal of Basic and Applied Sciences, 2023
Background In the pathophysiology of the retina, the epithelial–mesenchymal transition and oxidative stress play key roles. To find a relationship between oxidative stress and diabetic retinopathy or proliferative retinopathy, we used an in-silico ...

Ocular immune privilege and retinal pigment epithelial cells

Journal of Leukocyte Biology, 2023
AbstractThe ocular tissue microenvironment is immune-privileged and uses multiple immunosuppressive mechanisms to prevent the induction of inflammation. The retinal pigment epithelium plays an essential role in ocular immune privilege. In addition to serving as a blood barrier separating the fenestrated choriocapillaris from the retina, the retinal ...

Cross-talk between microRNA-let7c and transforming growth factor-β2 during epithelial-to-mesenchymal transition of retinal pigment epithelial cells [PDF]

International Journal of Ophthalmology, 2020
AIM: To explore the roles of microRNA-let7c (miR-let7c) and transforming growth factor-β2 (TGF-β2) and cellular signaling during epithelial-to-mesenchymal transition (EMT) of retinal pigment epithelial cells. METHODS: Retinal pigment epithelial (ARPE-19)

Biochemical adaptations of the retina and retinal pigment epithelium support a metabolic ecosystem in the vertebrate eye

eLife, 2017
Here we report multiple lines of evidence for a comprehensive model of energy metabolism in the vertebrate eye. Metabolic flux, locations of key enzymes, and our finding that glucose enters mouse and zebrafish retinas mostly through photoreceptors ...

Retinal Pigment Epithelial Cells Release Inhibitors of Neovascularization

Ophthalmology, 1987
Human retinal pigment epithelial (RPE) cells in culture were found to release a substance (or substances) that causes the regression of new blood vessels on the chick embryonic yolk sac and inhibits proliferation of fetal bovine aortic endothelial cells and human retinal microvessel endothelial cells in vitro.

Osteopontin and fibronectin levels are decreased in vitreous of autoimmune uveitis and retinal expression of both proteins indicates ECM re-modeling. [PDF]

, 2011
Autoimmune uveitis is an intraocular inflammation that arises through autoreactive T-cells attacking the inner eye, eventually leading to blindness. However, the contributing molecular pathomechanisms within the affected tissues remain as yet elusive ...

Effects of the Calix[4]arene Derivative Compound OTX008 on High Glucose-Stimulated ARPE-19 Cells: Focus on Galectin-1/TGF-β/EMT Pathway

Molecules, 2022
Diabetic retinopathy (DR) is a neurovascular disease characterized by the reduction of retina integrity and functionality, as a consequence of retinal pigment epithelial cell fibrosis.
