This study reveals that Naloxone (NLX) has a protective effect against oxidative stress induced by hydrogen peroxide (H2O2) in PC12 cells. NLX reduces intracellular reactive oxygen species (ROS) production, apoptosis levels, and prevents G2/M phase cell cycle distribution and cellular damage. Electrochemical experiments further confirm the antioxidant properties of NLX.
Background: Experimental evidence indicates that Naloxone (NLX) holds antioxidant properties. The present study aims at verifying the hypothesis that NLX could prevent oxidative stress induced by hydrogen peroxide (H2O2) in PC12 cells.Methods: To investigate the antioxidant effect of NLX, initially, we performed electrochemical experiments by means of platinum-based sensors in a cell-free system. Subsequently, NLX was tested in PC12 cells on H2O2induced overproduction of intracellular levels of reactive-oxygen-species (ROS), apoptosis, modification of cells' cycle distribution and damage of cells' plasma membrane.Results: This study reveals that NLX counteracts intracellular ROS production, reduces H2O2-induced apoptosis levels, and prevents the oxidative damage-dependent increases of the percentage of cells in G2/M phase. Likewise, NLX protects PC12 cells from H2O2- induced oxidative damage, by preventing the lactate dehydrogenase (LDH) release. Moreover, electrochemical experiments confirmed the antioxidant properties of NLX.Conclusion: Overall, these findings provide a starting point for studying further the protective effects of NLX on oxidative stress.
