1. Primary Research Focus: Phospholipid Metabolism in Saccharomyces cerevisiae

The main research focus in my laboratory involves events that occur within or near cellular membranes. I am interested in membrane lipid synthesis and degradation, and the fate of the resulting metabolites. These processes are complex, because as cells and organelles change size and shape with cell division, secretion, and membrane biogenesis, the various lipid classes must be broken down and resynthesized in a controlled manner. The regulation of this metabolism must take into account not only the concentrations and locations of individual lipids, but also the production of lipid-derived second messenger molecules, and the environmental conditions under which the cells are growing. Defects in lipid homeostasis can contribute to the development of several diseases, including obesity, diabetes, and cancer.

The production, transport, metabolism and function of a class of phospholipid metabolites called glycerophosphodiesters is an area of focus in my laboratory. We use the simple and genetically tractable eukaryotic organism, S. cerevisiae, for these studies. Glycerophosphodiesters, such as glycerophosphocholine and glycerophosphoinositol, are produced through phospholipase B-mediated cleavage of their precursor phospholipids. Once produced, the glycerophosphodiesters are transported across the cell membrane via specific transporters. My laboratory has characterized a number of genes involved in this metabolism in S. cerevisiae, including a permease (Git1), a glycerophosphodiesterase (Gde1), and an acyltransferase (Gpc1). The fundamental importance of this metabolism is illustrated by the fact that its basic components have been described in organisms and cell types spanning the biological spectrum. Although this metabolism is universal, many of its molecular details remain to be uncovered. A focus of the laboratory is to use biochemical and molecular genetic techniques to dissect the regulation and function of lipid turnover, metabolite recycling and membrane remodeling.

2. Secondary Research Focus: Phospholipid Metabolism in Candida albicans

Candida albicans is a pathogenic yeast of significant medical importance. The genome of C. albicans contains homologs of the genes involved in our metabolism of interest (see paragraph above). We are analyzing those genes and related processes for their roles in cellular physiology and virulence.

We acknowledge funding from NIH, PA Department of Health, and USDA for the above studies. Mass spectrometry instrumentation obtained through an NSF grant is utilized for these analyses.
