PURPOSE To test whether eliprodil (SL 82.0715), a unique antagonist for the N-methyl-D-aspartate (NMDA) receptor, is protective in the glutamate-induced cytotoxicity model in cultured rat retinal ganglion cells (RGCs). METHODS Two to four days after a fluorescent dye, Di-I, was injected near the superior colliculi, neonatal rats were killed, and retinal cells were dissociated and cultured. Su...
Effects of the kampo medicine yokukansan on gene expression of the cystine/glutamate antiporter system Xc-, which protects against glutamate-induced cytotoxicity, were examined in Pheochromocytoma cells (PC12 cells). Yokukansan inhibited glutamate-induced PC12 cell death. Similar cytoprotective effects were found in Uncaria hook. Experiments to clarify the active compounds revealed that geissos...
PURPOSE The purpose of the present study was to investigate the role of glutathione peroxidase 4 (GPx4) in glutamate-induced oxytosis in the retina. METHODS For in vitro studies, an immortalized rat retinal precursor cell line R28 was used. Cells were transfected with siRNA specifically silencing GPx4 or with scrambled control siRNA. Lipid peroxidation was evaluated by 4-hydroxy-2-nonenal (4-...
Oxidative stress has been implicated as an important factor in many neurological diseases. Oxidative toxicity in a number of these conditions is induced by excessive glutamate release and subsequent glutamatergic neuronal stimulation. This, in turn, causes increased generation of reactive oxygen species (ROS), oxidative stress, excitotoxicity, and neuronal damage. Recent studies indicate that t...
Glutamate toxicity is estimated to be the key cause of photoreceptor degeneration in the pathogenesis of retinal degenerative diseases. Oxidative stress and Ca(2+) influx induced by glutamate are responsible for the apoptosis process of photoreceptor degeneration. Puerarin, a primary component of Kudzu root, has been widely used in the clinical treatment of retinal degenerative diseases in Chin...
Objective(s): The present study was designed to evaluate of Metformin/Irinotecan-loaded poly-lactic-co-glycolic acid (PLGA) nanoparticles (NPs) effects on glutamate re-uptake time and receptor expression status in both glioblastoma multiforme (GBM) and cortex neuron cultures. The study was performed on glioblastoma cell line and primer cortex neuron.Materials and Methods: The re-uptake time and...
Lithium, besides mood stabilization, might be involved in neuroprotection. Previously we have found that the treatment with lithium increased the levels of p21(WAF/Cip1 and survivin in human glioblastoma A1235 cells. The aim of the present study was to examine the cytotoxic effect of glutamate on these cells, and to determine whether lithium can protect A1235 cells against toxic effects of glut...
