Phosphorylation of c-Jun in wildtype (WT) and IKKβ-deficient MC3T3–E1 cells. (A,B) Representative data of phospho-c-Jun (A) at 60 min after β-GP and AA stimulation, and mean fluorescence intensity (MFI) of phospho-c-Jun (B) at 0, 60, and 120 min after β-GP and AA treatment, compared between WT and IKKβ-deficient cells (n = 5). Statistics by one-way ANOVA. (C) Western blot analysis for phospho-c-Jun proteins in WT and IKKβ-deficient MC3T3–E1 cells after the treatment described in B. Images were representatives of three independent experiments. (D) Representative immunofluorescence images of phospho-c-Jun in WT and IKKβ-deficient MC3T3–E1 cells after 0, 60 min treatment with β-GP and AA. Scale bars: 50 μm. Error bars represent ± SEM. ***P < 0.001, ns = not significant.
