Project description:We investigated the transcriptomic response to territorial intrusion in four regions of the brain (telencephalon, diencephalon, cerebellum and brain stem) of a teleost fish, the threespined stickleback (Gasterosteus aculeatus). We tested the hypothesis that gene regulatory networks modulate the transcriptional response to territorial intrusion in the different brain regions and thereby aggressive behavior. Indeed, transcription regulatory network analysis identified cis-regulatory transcription factor motifs enriched in upregulated genes in one brain region and downregulated in the others. We further validated our findings by showing that many of the differentially expressed genes in the diencephalon were positively correlated with levels of aggression in individual males. 2 conditions: control fish and fish that experienced intrusion into their territory, Biological replicates 5.Four brain regions. Sample 4BS was excluded from the analysis during data preprocessing because it was an outlier.

Project description:Animals exhibit dramatic immediate behavioral plasticity in response to social interactions, and brief social interactions can shape the future social landscape. However, the molecular mechanisms contributing to behavioral plasticity are unclear. Here, we show that the genome dynamically responds to social interactions with multiple waves of transcription associated with distinct molecular functions in the brain of male threespined sticklebacks, a species famous for its behavioral repertoire and evolution. Some biological functions (e.g., hormone activity) peaked soon after a brief territorial challenge and then declined, while others (e.g., immune response) peaked hours afterwards. We identify transcription factors that are predicted to coordinate waves of transcription associated with different components of behavioral plasticity. Next, using H3K27Ac as a marker of chromatin accessibility, we show that a brief territorial intrusion was sufficient to cause rapid and dramatic changes in the epigenome. Finally, we integrate the time course brain gene expression data with a transcriptional regulatory network, and link gene expression to changes in chromatin accessibility. This study reveals rapid and dramatic epigenomic plasticity in response to a brief, highly consequential social interaction.
