Lycium barbarum polysaccharides protected human retinal pigment epithelial cells against oxidative stress-induced apoptosis.
AIM To investigate the protective effect and its mechanism of lycium barbarum polysaccharides (LBP) against oxidative stress-induced apoptosis in human retinal pigment epithelial cells. METHODS ARPE-19 cells, a human retinal pigment epithelial cell lines, were exposed to different concentrations of H2O2 for 24h, then cell viability was measured by Cell Counting Kit-8 (CCK-8) assay to get the ...
متن کاملRetinal Pigment Epithelium Is Protected Against Apoptosis by B-Crystallin
PURPOSE. The degeneration of retinal pigment epithelial (RPE) cells is considered to be a crucial event in the pathophysiology of age-related macular degeneration (AMD). Cumulative oxidative damage has been implicated in the development of the changes seen in AMD. The present study was undertaken to evaluate the expression of the small heat shock protein Bcrystallin in the RPE in response to ox...
متن کاملBidirectional glutathione transport by cultured human retinal pigment epithelial cells.
PURPOSE To characterize glutathione (GSH) transport by cultured human retinal pigment epithelial (HRPE) cells. METHODS Cultured HRPE cells were pretreated with acivicin for GSH efflux and with buthionine sulfoximine for GSH uptake to prevent the breakdown and resynthesis of GSH. Efflux was measured by the linear rate of accumulation of GSH in the supernatant; uptake was measured using [35S] G...
متن کاملCD68 antigen expression by human retinal pigment epithelial cells.
Although a primary role of the retinal pigment epithelium (RPE) is the phagocytosis of aged outer segment membranes, the RPE may also phagocytize particulates via several specific receptors that are characteristically present on mononuclear phagocytes of bone marrow origin. In recent immunophenotypic studies, CD68 monoclonal antibodies (mAb) have been shown to react selectively with a specific ...
متن کاملUptake by Retinal Pigment Epithelial Cells
Uptake of Ca was studied in isolated frog retinal pigment epithelial cells. Ca accumulation was found to be a saturable, temperature-dependent event. Kinetic analysis of this accumulation revealed two transport systems with apparent km of 2.0 and 0.3 mM. We found the presence of a Na-Ca exchanger mechanism that releases Ca under depolarized conditions. Light induced an increase of Ca uptake due...
