Olfactory SEK1/MKK4 and PKA are differentially activated across Braak stages in human AD. Levels and residue-specific phosphorylation of SEK1/MKK4 (A), and PKA (B) in the OB across AD phenotypes. Equal loading of the gels was assessed by Ponceau staining and hybridization with a GAPDH specific antibody. Right panels show histograms of band densities. Data are presented as mean ± SEM from five independent OB samples per group. *P < 0.05 vs. control group; ***P < 0.001 vs. control group. Representative Western blot gels are shown.
