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 are interested in understanding how intracellular signaling is compartmentalized and regionally controlled by lipid modifications that modulate the function of signaling molecules to control cardiac physiology and pathogenesis. We utilize 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 we are actively investigating is how the zDHHC family of S-acyl transferase enzymes control signaling in cardiac cells. We found palmitoylation of signaling proteins catalyzed by some of these enzymes at the surface of the cardiomyocyte Golgi membrane functions as a critical mechanism governing cardiac stress adaptation and remodeling, including instrumental roles in regulation of exocytosis and natriuretic peptide release and cytokine receptor signaling. We have a broader interest in identifying and elucidating pharmacological strategies to inhibit intracellular signaling pathways that promote cardiac hypertrophy and failure or that promote adaptive signaling circuitry to aide in cardiac resiliency to chronic insult with the goal of reducing or preventing adverse cardiac remodeling that ultimately results in heart failure. .
