The Brody Lab

The University of Michigan

The Brody lab is broadly focused on the molecular signals that underlie cardiac disease onset and progression. We have a specific interest in understanding how intracellular signaling is compartmentalized and regionally controlled by lipid modifications that modulate the function of signaling molecules in various cell types of the heart to control cardiac physiology and pathogenesis. Our laboratory utilizes a combination of mouse genetics, biochemistry, and molecular and chemical biology techniques to gain insight into pathophysiological signaling mechanisms that contribute to human cardiovascular disease.

Research

One area the Brody lab is actively investigating is how the DHHC family of S-acyl transferase enzymes control signaling through lipid modifications. Our work has shown that DHHC3 transferase activity at the cardiomyocyte Golgi apparatus is a nodal point for reactive signaling in the heart including functioning as a key regulator of signaling by the Rho family of small GTPases with profound effects on cardiac remodeling and failure. We have a broad interest in signaling mediated by G-protein-coupled receptors and small GTPases in the context of cardiac disease. We are using transgenic and gene-targeted mouse models and cellular, molecular, and biochemical studies to elucidate how DHHC enzymes regulate signaling molecules in the heart and determine how specific lipid modifications alter protein function to control cardiac physiology and disease.
