Aberrant histone H3 serotonylation dynamics in dorsal raphe nucleus contribute to maladaptive stress-induced gene expression programs and behavior [ChIP-seq]

Project description:Major depressive disorder (MDD) is a debilitating illness that affects millions of individuals worldwide. While chronic stress increases incidence levels of MDD, stress-mediated disruptions in brain function that precipitate the disorder remain elusive. Serotonin-associated antidepressants (ADs) remain the first line of therapy for many with MDD, yet low remission rates and delays between treatment and symptomatic alleviation have prompted skepticism regarding precise roles for serotonin in the precipitation of MDD. Our group recently demonstrated that serotonin epigenetically modifies histone proteins (H3K4me3Q5ser) to regulate transcriptional permissiveness in brain. However, this phenomenon has not yet been explored following stress and/or AD exposures. Here, we employed a combination of genome-wide (ChIP-seq, RNA-seq) and western blotting analyses in dorsal raphe nucleus (DRN) of male and female mice exposed to chronic social defeat stress to examine the impact of stress exposures on H3K4me3Q5ser dynamics in DRN, as well as associations between the mark and stress-induced gene expression. Stress-induced regulation of H3K4me3Q5ser levels were also assessed in the context of AD exposures, and viralmediated gene therapy was employed to manipulate H3K4me3Q5ser levels to examine the impact of reducing the mark in DRN on stress-associated gene expression and behavior. We found that H3K4me3Q5ser plays important roles in stress-mediated transcriptional plasticity in DRN. Mice exposed to chronic stress displayed dysregulated dynamics of These findings establish a neurotransmission-independent role for serotonin in stress-associated transcriptional and behavioral plasticity in DRN.

Project description:A small block of the midbrain containing the dorsal raphe nucleus was obtained from ovariectomized monkeys treated with placebo, estrogen, progesterone or estrogen plus progesterone for one month. The RNA was extracted and hybridized to the Rhesus Affymetrix chip. The results were analyzed with GCOS 1.0 Each chip represents one monkey. N=3 monkeys per treatment.
