| dc.description.abstract | Mice naturally form social hierarchies and their experiences as subordinate or dominant mice inform future behavioural strategies. To better understand the neural bases of social dominance, we investigated hippocampal gene and protein expression of histone deacetylase 2 (HDAC2), an epigenetic regulator that decreases expression of synaptic plasticity genes and reduces excitatory synaptic function. Hdac2 in hippocampus was associated with social status. The gene for a closely related histone deacetylase (Hdac1), and HDAC2 protein expression, were not associated with social rank in hippocampus. These findings suggest that Hdac2 expression in hippocampus is distinctly linked with social status. | en_US |
