The laboratory focuses on the mitochondrial pathway of apoptosis with particular interest in the BCL-2 family of proteins. The mitochondrial pathway of apoptosis is activated during metazoan development, and is utilized for maintenance of adult tissues following both physiological signaling and cellular stress scenarios. Importantly, the mitochondrial pathway of apoptosis is often engaged following chemotherapeutic treatment, yet malignant cells have devised clever mechanisms to block activation of this pathway to ensure survival. Our main goal is to understand the BCL-2 family in the context the cellular milieu with hopes to gain fundamental insights into the physiological and patho-physiological mechanisms of apoptosis. We utilize several model systems to explore BCL-2 family function, including ethanol-induced stress and cellular models of melanoma.

Our current research interests are divided into three areas, but adopt a unified theme to decipher the interplay between mitochondrial function and cell death pathways:
I. What are the biochemical, physiological, and structural consequences of protein·protein interactions within the BCL-2 family?
II. How does the mitochondrial environment influence BCL-2 family function and the core cell death machinery?
III. How do oncogenic and tumor suppressor signals intersect with the core cell death machinery and metabolic pathways to regulate tumorigenesis and chemosensitivity?
