Exposure to an obesogenic diet and chronic psychosocial stress influence corticosterone levels and hippocampal Fkbp5 gene expression. (A) Fecal corticosterone metabolite (FCM) levels were significantly decreased by the WD (p = 0.0018). (B) We observed significant effects of WD (p = 0.0052), PSS (p = 0.0008), and their interaction (p = 0.039) following the first day after predatory exposure. PSS significantly increased FCM levels in the WD rats (p = 0.0012). (C) FCM remained significantly elevated in PSS rats 24 h after the second predatory exposure (p = 0.0250). (D) Hippocampal Fkbp5 mRNA levels were significantly decreased by the WD (p = 0.0016) and PSS (p = 0.020). RT-PCR: 3 rats/group.
