Biography
My research has focused primarily on the cellular and molecular regulation of gene expression within CNS dopamine (DA) neurons and their forebrain targets, including dysfunctional gene expression in brain disorders. In particular, we have used complementary approaches encompassing cell culture, animal models, and human postmortem brain to investigate the biological processes contributing to drug abuse and Parkinson's disease.
1. One of my initial lines of research led to the identification of important differences in the physiological characteristics, drug responsiveness, and susceptibility to disease among subgroups of midbrain DA neurons. Early work entailed rodent studies, but this was subsequently expanded to the analysis of human midbrain.

2. Given the physiological interactions between DA cells and certain tachykinin-producing neurons, we next conducted some seminal studies aimed at better understanding the cellular distribution, regulation of gene expression, RNA alternative splicing, and physiological effects of tachykinin neuropeptides and their related neurokinin receptors.

3. The DA transporter plays a critical role in regulating extracellular DA levels. It is also a primary site of action for cocaine and other stimulants, as well as for the accumulation of neurotoxins that induce parkinsonism. A primary focus of the lab for a number of years was to increase our understanding regarding the regulation of DA transporter gene expression, including the basis for its exquisite DA cell-specificity of expression.

4. Recently, as part of an international consortium, we have used this information to develop a novel strategy to rescue and enhance the functionality of surviving DA cells in animal models of Parkinson’s disease. The approach entails the regulated expression of trophic factors selectively within DA neurons, which we achieve by coupling receptor-mediated polyplex transfection of DA neurons with DA cell-specific transgene expression under the control of either the DA transporter gene promoter or a nurr1 response element we determined was critical for maintenance of DA phenotype.

5. Persistent cellular and behavioral adaptations seen in drug addiction are encoded by long-lasting alterations in CNS gene expression. For a number of years now, we have followed the less common path of investigating such changes in human postmortem brain from cocaine or opioid abusers. Some studies have focused in detail on specific candidate genes, while other investigations have been more unbiased and discovery-driven in nature. Illustrative of the power of discovery-driven studies, we identified robust (but completely unanticipated) changes in the expression of myelin-related genes that were specific to cocaine abusers and for which clinical correlates have been identified. Ongoing collaborative projects continue to identify key molecular changes in brain regions and networks involved in human drug abuse.
