Title | Chronic stress and antidepressant treatment alter purine metabolism and beta oxidation within mouse brain and serum |
Overall design | The aim of this study was to perform metabolomic, lipidomic, and proteomic profiling on serum plus several brain regions (ventral hippocampus, nucleus accumbens, and medial prefrontal cortex) of susceptible, resilient, and unstressed control mice. Chronic social defeat stress (CSDS) model of depression was established. To identify how commonly used tricyclic antidepressants impact the molecular composition in these tissues, stress-exposed mice were then treated with imipramine. C57BL/6 J mice were divided into the following 4 groups: (1) control group (no stress for 10 days), (2) CSDS group (social defeat stress for 10 days), (3) CSDS + vehicle group (social defeat stress for 10 days, and then treated with vehicle for 14 days after stress), and (4) CSDS + imipramine group (social defeat stress for 10 days, and then treated with imipramine for 14 days after stress, i.p. twice-daily at the dose of 10 mg/kg). Stressed mice were characterized as susceptible (social interaction ratio < 1) or resilient (social interaction ratio > 1). |
