Celecoxib, indomethacin and ibuprofen prevent 6-hydroxydopamine-induced PC12 cell death through the inhibition of NFκB and SAPK/JNK pathways

Abstract

Objective(s): The possible action of nonsteroidal anti-inflammatory drugs (NSAIDs) in the reduction of reactive oxygen species (ROS) and also as anti-apoptotic agents may suggest them as putative agents for the treatment of neurodegenerative diseases. This study was designed to explore some pathways alterations induced by NSAIDs following 6-hydroxydopamine (6-OHDA)-induced cell death in PC12 cells as an in vitro model of Parkinson's disease (PD) and to compare the effects of celecoxib, indomethacin and ibuprofen.Materials and Methods: The cell viability, ROS content, glutathione (GSH) level, and apoptosis were measured using resazurin, dichlorofluorescein diacetate (DCFH-DA), 5,5′-dithiobis-2-nitrobenzoic acid (DTNB), propidium iodide (PI) and flowcytometry, real-time PCR and western blot.Results: Based on the results, pretreatment with celecoxib, indomethacin and ibuprofen for 24 hr significantly induced concentration and time-dependent protection against 6-OHDA-induced PC12 cell death.
