FIGURE 2.

Expression analysis of the abnormally expressed proteins identified in the depression-susceptible (Dep-Sus), anxiety-susceptible (Anx-Sus), and insusceptible (Insus) groups. (A) Venn diagrams displaying the number of abnormally expressed proteins. (B) PCA of the abnormally expressed proteins based on their fold changes in the three stressed groups relative to the control (Ctrl) group. (C) Hierarchical clustering of the abnormally abundant proteins representing log2 of their fold changes in the three stressed groups in relative to the Ctrl group. Red represents upregulation, and blue represents downregulation with darker shades indicating greater changes in expression. The eight isobaric tags used are shown.
