DEZ decreased the inflammation and oxidative stress in IL-1β induced HNPCs. (a) The expression of IL-6 and TNF-α was assessed by RT-qPCR after treatment with various concentrations of DEZ in HNPCs treated with IL-1β. (b) ELISA was adopted to evaluate the contents of IL-6 and TNF-α. (c) The protein levels of p-NF-κB p65, p65 expression in nucleus, p65 expression in cytoplasm and cox-2 were examined with Western blot analysis. (d) The ROS content was tested by means of the 2ʹ, 7ʹ-dichlorodihydrofluorescein diacetate (DCFH-DA) staining method. The levels of (e) MDA and (f) GSH were measured using commercial kits. (g) Western blot assay was utilized to determine the protein levels of SOD1 and SOD2. ***P < 0.001 vs. untreated group; #P < 0.05, ##P < 0.01, ###P < 0.001 vs. IL-1β group.
