Insulin In Combination With N-Acetylcysteine Protects Hypoxia-Induced Toxicity In 661w Cells, Lili M. Guerra, Laura Valdez, Benxu Cheng, Andrew Tsin

Research Colloquium

Background: Proliferative diabetic retinopathy (PDR) is the leading cause of blindness among working-age adults. Photoreceptors are the most numerous and metabolically demanding cells in the retina thus oxygen is essential for retinal function. It has been reported that photoreceptors found in rat retina are specifically vulnerable to hypoxia. Hypoxia-induced metabolic stress leads to photoreceptor atrophy and retinopathy. Furthermore, photoreceptor cell death is known to occur mainly through apoptosis. However, the protection of hypoxia-induced-cytotoxicity in cone photoreceptor cells has not been investigated extensively. The aim of this study was to determine whether co-treatment of insulin and the N-Acetyl-L-Cysteine (NAC) (a free …
