Research Interest: Epigenetics & Chromatin Biology

Pruitt lab research involves 3 broad areas. Interest in the first area (cancer epigenetics) stemmed from discoveries made during postdoctoral training assessing how tumor progression disrupts epigenetic mechanisms of control. The second area (Wnt pathway regulation) was the result of early screens as an Assistant Professor at LSU Health Sciences Center. We uncovered novel regulators of oncogenic Wnt signaling and published the first observation that epigenetic enzymes regulate a critical mediator of Wnt signaling (Dishevelled). The third project involves elucidating mechanisms of aromatase regulation which emerged from the obsession of early trainees in the lab with understanding mechanisms cancer-associated estrogen biosynthesis. Within the context of these three projects, I have mentored and guided multiple trainees at every level over the course of 17 years.

My research interests involve investigation of proinflammatory neuroimmune and epigenetic mechanisms in animal models of developmental neurobiology and neurodegeneration, including (1) alcohol pharmacology, (2) alcohol responsivity and tolerance, (3) adolescent neurodevelopment, (4) cholinergic system and neurocircuitry, (5) microglial function, and (6) Alzheimer’s disease. A major focus of the laboratory is elucidation of neuroimmune and epigenetic mechanisms underlying adolescent binge alcohol-induced disruption of basal forebrain cholinergic neurocircuitry in adulthood. A second major focus of the laboratory is investigation of lasting adolescent binge drinking-induced neuroimmune priming as a novel etiological factor contributing to the onset and progression of basal forebrain neuropathology in Alzheimer’s disease. Our laboratory combines ex vivo and in vivo rodent models of alcohol abuse and Alzheimer’s disease with innovative molecular techniques.
