Role of PPAR-gamma ligands in neuroprotection against glutamate-induced cytotoxicity in retinal ganglion cells.
PURPOSE The peroxisome proliferator-activated receptor-gamma (PPAR-gamma) is the target of the insulin sensitizing thiazolidinediones (TZDs), a class of drugs used in the treatment of type 2 diabetes mellitus. Glaucoma and other retinal disorders are some of the major complications in diabetes. In the present study, the role that PPAR-gamma ligands play in protecting retinal ganglion cells (RGC...
متن کاملChloride channel protein 2 prevents glutamate-induced apoptosis in retinal ganglion cells
Objective(s): The purpose of this study was to investigate the role of chloride channel protein 2 (ClC-2) in glutamate-induced apoptosis in the retinal ganglion cell line (RGC-5). Materials and Methods: RGC-5 cells were treated with 1 mM glutamate for 24 hr. The expression of ClC-2, Bax, and Bcl-2 was detected by western blot analysis. Cell survival and apoptosis were measured by 3-(4,5-dimeth...
متن کاملMolecular basis of glutamate toxicity in retinal ganglion cells
Loss of retinal ganglion cells (RGCs) is a hallmark of many ophthalmic diseases including glaucoma, retinal ischemia due to central artery occlusion, anterior ischemic optic neuropathy and may be significant in optic neuritis, optic nerve trauma, and AIDS. Recent research indicates that neurotoxicity is caused by excessive stimulation of receptors for excitatory amino acids (EAAs). In particula...
متن کاملParkin overexpression protects retinal ganglion cells against glutamate excitotoxicity
PURPOSE To investigate the role of parkin in regulating mitochondrial homeostasis of retinal ganglion cells (RGCs) under glutamate excitotoxicity. METHODS Rat RGCs were purified from dissociated retinal tissue with a modified two-step panning protocol. Cultured RGCs were transfected with parkin using an adenovirus system. The distribution and morphology of mitochondria in the RGCs were assess...
متن کاملNeuroprotection of retinal ganglion cells by brimonidine in rats with laser-induced chronic ocular hypertension.
PURPOSE To examine the neuroprotective effect of the alpha(2)-adrenergic agonist brimonidine in a chronic ocular hypertension model. METHODS Intraocular pressure (IOP) was elevated by laser photocoagulation of episcleral and limbal veins. Retinal ganglion cell loss was evaluated in wholemounted retinas. Brimonidine or timolol was administered, either at the time of or 10 days after IOP elevat...
