Faculty Research Labs

Hurley Lab

The major focus of Dr. Hurley’s research lab is to understand, at the molecular level, the processes involved in the recognition and binding of molecules that are directed to the active sites of enzymes. The main approaches utilized in our laboratory are X-ray crystallography, inhibitor screening, detailed enzyme kinetics and mass spectrometry.

Active Research

Model of aldehyde dehydrogenases Aldehyde Dehydrogenases

A major focus is to correlate the structural and functional characteristics of aldehyde dehydrogenases as they impact cellular function.  The goal of our project is to understand the catalytic function of this important enzyme family and how manipulation of its activity through the design of small molecule modulators of its activity can affect disease outcomes. In particular, our laboratory has become interested in the roles of aldehyde dehydrogenases from family 1A (ALDH1A; isozyme 1A1, 1A2 & 1A3) in chemoresistance in certain forms of cancer and as biomarkers for cancer stem cells, also known as cancer initiating cells. Toward this end we have pursue the discovery and development of small molecule inhibitors that demonstrate selectivity toward the different enzyme that we can use as chemical tools to probe the way these enzymes impact cancer cell survival. 


Model of glycogen synthesis Glycogen Synthesis

Our second major research direction is in collaboration with Dr. Anna Depaoli-Roach, where we are interested in the structural and functional properties of the major enzyme that controls glycogen synthesis; glycogen synthase. In particular, we are interested in how manipulation of glycogen synthase can impact the outcome of diseases associated with the over-accumulation of glycogen – so called glycogen storage diseases, such as Pompe, Cori and Lafora Disease. The goal of our collaboration is to discover and develop novel inhibitors that can block further accumulation of glycogen in cellular and mouse model systems of these diseases. To facilitate the discovery and development of the novel inhibitors our laboratory is using the structure and enzyme characteristics of glycogen synthase to inform both the medicinal chemistry and biological evaluation in cell and animal models from our collaborators.
