Research Intrest

Research in my laboratory addresses the molecular mechanisms by which cells become multidrug resistant. Such resistance to many different chemotherapeutic agents is a major problem in the treatment of cancer, malaria, and various fungal infections. Our work established that yeast cells (a model eukaryote) have several membrane proteins that modulate a basal level of drug resistance. Most of our effort has centered on understanding the regulation and function of the PDR5 gene product. The PDR5 locus encodes a large protein that is a member of the ABC (ATP-binding cassette) transport family. All of these proteins use the energy liberated from ATP hydrolysis to import or expel a variety of compounds depending upon the specificity of the particular transporter. Included in this family are the mammalian MDR1 multidrug-resistance efflux pump and the cystic fibrosis transmembrane regulator. PDR5 is a multidrug transporter that mediates resistance to many different compounds, including the well-known therapeutic agents fluconazole and adriamycin.
