S1 mice display behavior-dependent aberrant ChRF protein expression in the vHC. (A) CHD1 showed aberrant up-regulation (S6: n = 5; S1 and S1 ZnR: n = 6), (B) CHD3 failed to become down-regulated (S6: n = 5; S1 and S1 ZnR: n = 6), and (C) CHD5 was down-regulated (S6: n = 5; S1: n = 4 and S1 ZnR: n = 3) following prologed CS exposure in the vHC of extinction-deficient S1 mice. Different brain areas were dissected from S6, S1 and S1 ZnR mice 2 h after contextual fear expression or extinction training, nuclear proteins were extracted and subjected to western blot analysis with antibodies against different ChRFs. Western blot signals were quantified, normalized to TBP and expressed relative to values of the respective fear expression group (left panels). Mean values ± SEM are shown. Statistical significance of protein level differences was determined by Two-way ANOVA with Bonferroni's post-hoc test (*P < 0.05; ***P < 0.005). Right panels, representative western blots of significantly altered proteins are shown.
