Signaling pathways disrupted in the OB across AD grading. Levels and residue-specific phosphorylation of MKK3/6 (a), p38 MAPK, ATF2, and HSP27 (b), PDK1, and PKC (c) 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 5 independent OB samples per group. *P < 0.05 vs control group; **P < 0.01 vs control group. Representative Western blot gels (n = 3/experimental group) are shown. Full-length blots/gels are presented in Supplementary information.
