The Maze laboratory is focused on understanding the complex interplay between chromatin regulatory mechanisms in brain and neuronal plasticity. We combine a wide variety of biochemical, biophysical, molecular and behavioral approaches to assess the role of histone proteins, and their associated posttranslational modifications, turnover dynamics and remodeling activities, in the regulation of normal neurodevelopment, and the contribution of such processes, or aberrations thereof, to neurological and psychiatric disease. We place particular emphasis on psychiatric disorders associated with monoaminergic (e.g., serotonin, dopamine, etc.) dysfunction, such as major depressive disorder and drug addiction, as well as neurodevelopmental syndromes resulting in deficits in synaptic plasticity and intellectual disability (e.g., Down syndrome and autism). Being both ‘basic’ and translational in nature, our work – so-called “mechanistic neuroepigenetics” – employs state-of-the-art gene and chromatin arraying technologies, analytical chemistry (e.g., mass spectrometry and 14C bomb pulse labeling) and neurobiological phenotyping, in both rodents and humans (postmortem brain and iPSC derived neurons), to explore novel chromatin phenomena in the central nervous system. This includes the identification and characterization of neuronally enriched histone modifications, chromatin “readers,” “writers” and “erasers,” all of which play critical roles in neuronal plasticity and behavioral adaptation.

Histone serotonylation: a novel epigenetic mechanism mediating depressive-like phenotypes
The major goals of this young investigator award are to understand whether serotonergic dysfunction in
rodent models of human depression impact the expression of histone serotonylation in brain, as well as if
current antidepressants affect such expression.

Role of protein dopaminylation in drug addiction
The major goals of this project are to use novel chemical approaches to identify synaptic proteins that
are dopaminylated in the context of drug abuse (specifically cocaine and heroin) for future molecular
and behavioral characterizations.

Genome-wide chromatin accessibility profiling in major depressive disorder reveals astrocytic specific
signatures of reward processing deficits in the orbitofrontal cortex
The major goals of this training grant project are to investigate epigenetic mechanisms underlying human
major depressive disorder, with a specific emphasis on chromatin mediated glial dysfunction leading to
reward processing deficits in the frontal cortex.
