MORE ABOUT PROFESSOR HAMZA
Personal Statement:
Heme is a biological paradox: an iron-containing hydrophobic cofactor essential for oxygen transport, energy metabolism, and signaling, yet dangerously cytotoxic when unshielded. For more than six decades, a central problem in cell biology has remained unresolved: how eukaryotic cells import heme, move it across membranes, traffic it between organelles, and deliver it with precision to hemoglobin and other hemoproteins.
The mission of my research program is to close these long-standing gaps by defining the genes and pathways that govern heme transport and intracellular trafficking. The Hamza Lab pioneered a multi-organismal strategy centered on the genetic model C. elegans, a microscopic transparent animal that cannot synthesize heme and must acquire it from its environment. This unique dependency provided a powerful entry point to uncover conserved heme-handling machinery.
Using this platform alongside zebrafish, mice, and human systems, we identified HRG-1 as the first eukaryotic heme importer, establishing a conserved gateway for heme entry from worms to humans. We subsequently defined systemic distribution mechanisms, including intestinal export via HRG-3 and ABCC5/MRP5, and uncovered inter-organ communication circuits that coordinate organismal heme homeostasis.
Beyond fundamental physiology, our work reveals shared vulnerabilities in medically important heme-auxotrophic pathogens such as hookworms, filarial worms, and Leishmania, which rely on host-derived heme for survival. By integrating genetics, cell biology, biochemistry, and physiology, our long-term goal is to build a molecular blueprint of heme trafficking that informs new approaches to anemia, hemoglobin disorders, and host-pathogen competition.
