Abstract
We investigated the effects of25Mg-Porphyrin-Fullerene nanoparticles, (25MgPMC16) smart ferroporphyrin nanoparticles, on PC12 cells exposed to oxygen-glucose deprivation/reperfusion. In order to explore its effect on cells under oxygen-glucose deprivation conditions, the cultures were pretreated with25MgPMC16 24 hours prior to oxygen-glucose deprivation/reperfusion. To initiate the oxygen-glucose deprivation/reperfusion, the cell culture medium was replaced with a glucose-free medium and the cells were transferred to a humidified incubation chamber in a mixture of 95 N2 and 5 CO2 at 37° C for 30, 60 and 120 min. Cell viability was assessed by MTT assay. Exposure of PC12 cells to 30, 60 and 120 min oxygen-glucose deprivation significantly decreased the cell viability. Pretreatment of the cultures with25MgPMC16 significantly increased cell viability in a concentration-dependent manner. Pretreatment, the cultures with MK-801 (10 µM), a non-competitive NMDA antagonist, has attenuated the cell death after 30 min oxygen-glucose deprivation. We concluded that25MgPMC16 could protect PC12 cells against oxygen-glucose deprivation/reperfusion-induced cell injury in a concentration-dependent manner. That could be due to the effect of25MgPMC16 on ATP synthesis and the antioxidant effects of its components. © 2016 Tehran University of Medical Sciences. All rights reserved
