Huntington’s disease (HD) is a fatal neurodegenerative disorder resulting from the expansion of a trinucleotide repeat within the HD gene. At the cellular level mutant HTT (mHTT) aggregates perturb cellular metabolism, intracellular trafficking and mitochondrial function, resulting in the increased production of reactive oxygen species (ROS) an event closely linked with nerve cell death. Nuclear factor erythroid 2-related factor 2 (NRF2) is a redox-sensitive transcription factor responsible for transcribing neuroprotective genes under the control of the antioxidant response element (ARE), which work to counteract high intracellular ROS levels. I have identified significant increases in cell viability, NRF2 nuclear localization, and …

Schizophrenia affects about 1% of the population. A hallmark of the disorder is increased dopamine D2 receptor sensitivity in the brain. Studies have shown that schizophrenics smoke cigarettes at approximately 4 times the rate of the general population. It has been suggested that nicotine use is a form of self-medication for symptoms in schizophrenia. Smoking behaviors typically begin in adolescence. We assessed effects of nicotine on behavior and brain plasticity in an adolescent rodent model of schizophrenia with the goal of identifying targets for smoking cessation. Methods: Rats were neonatally treated with quinpirole (a D2/D3 agonist) or saline and sensitized …
