Quantitative RT-PCR of myelin gene transcripts in (A) prefrontal cortex (PFC), (B) nucleus accumbens (NAc), (C) corpus callosum (CC) and (D) amygdala (AMG) in mice following 28 days of CVS. Bar graphs indicate average values in stressed mice after Gapdh normalization relative to average control levels (dashed line) (n=5–6 mice per group, * two-tailed unpaired t-test, FDR < 0.05). Note the decreased myelin gene transcripts in the PFC and NAc, while increased myelin gene transcripts in the corpus callosum (CC). Data represented as mean ± S.E.M.
