The mission of the Cancer Biology Laboratory is to develop smart cancer therapeutics with increased potency and decreased side effects.
We use phage display screens to identify homing peptides that bind to specific targets in the vasculature. Corresponding synthetic peptides are explored for targeting drugs, biologicals, and nanoparticles into tumors to increase their therapeutic index. Our scope includes understanding the molecular interactions involved to drive specificity and activity, focusing on Tumor Penetrating Peptides (TPP) that trigger bulk extravascular transport in the tumor tissue.
