Figure 4.
PKA phosphorylation is decreased in the medial prefrontal cortex (mPFC), but not in the amygdala (amy), of PCP-treated rats. Effects of PCP on PKA expression (normalized to β-actin; center panel) and phosphorylation (pPKA; normalized to PKA; right panel) in the (a) amygdala (F1,10=11.01, p<0.01 and F1,11=2.04, NS for PKA and pPKA, respectively) and (c) mPFC (F1,11=4.19, p=0.065 and F1,10=16.63, p<0.01 for PKA and pPKA, respectively). Left panels show representative western blot data. Values are expressed as percentage of control (mean±SEM; n=6–7 per group). *p<0.05 compared with saline-treated rats. (b) Correlation analysis of PKA and AEA levels in the amygdala. (d) Correlation analysis of pPKA and AEA levels in the mPFC.
