Oxidative stress contributes to the degeneration of retinal pigment epithelial (RPE) cells and photoreceptors that lead to the dry form of age-related macular degeneration. Activation of N-Methyl-D-aspartate (NMDA) receptors contributes to the increase of free radicals that induce oxidative stress-induced changes. Our study investigates if Dextromethorphan, an NMDA receptor antagonist, reverses oxidative stress-induced changes in RPE. We used Paraquat and H2O2 as oxidative stress-inducing agents to induce oxidative damage in human ARPE-19 cells. To illustrate the change in cell viability and measure the apoptosis of ARPE-19 cells from oxidative damage, we performed MTT assay and Annexin V-DAPI flow cytometry analysis. …
