Effects of tempol on IL-1β-induced inflammatory cytokines gene expression. qRT-PCR performed with IL-1β (B), IL-6 (C) and TNF-α (A) on IL-1β-stimulated CC and treated with tempol (0.5 and 1.0 mM) for 24, 72 and 168 h. GAPDH was used as endogenous controls. CTR, untreated CC; IL-1β, IL-1β-stimulated CC; IL-1β+tempol, IL-1β-stimulated CC and treated with tempol 0.5 and 1.0 mM. Data are representative of at least three independent experiments. One-way ANOVA test. ° compare the LPS-tempol group 72 h to IL1 beta group; ***
