Description of Research Expertise

Research Interests
Tumor angiogenesis, tumor physiology, antiangiogenesis tumor therapy, noninvasive tumor imaging.

Key words: cancer, angiogenesis, experimental therapy.

Description of Research
The requirement during tumor growth for blood perfusion and a vasculature that supports it has led us to study vascular development in tumors, antiangiogenic approaches to cancer therapy, and the tumor metabolic and physiologic consequences of this therapy. Our studies have identified an ordered series of tumor vessel developmental and maturation events not unlike that described during physiologic angiogenesis. Tumor vessel maturation affects the response to antiangiogenic agents inasmuch as more mature vessels, characterized by pericyte coverage of the vascular endothelial cells, are relatively resistant to these agents while less mature vessels are relatively susceptible. The loss of vessels with therapy results in or worsens tumor ischemia and ischemic cell death, which is the mechanism underlying tumor growth control. These findings have led us to develop autochthonous murine tumor models that more closely recapitulate the vasculature in human cancers, which have a more mature vascular profile and may be more resistant to antiangiogenic therapy than commonly used transplanted mouse tumors. We are identifying signal transduction pathways activated in vascular endothelial cells in tumors that correlate with angiogenesis, vessel maturation and regression during therapy, so that we can assign molecular signatures to these vascular events. Finally, we are seeking noninvasive ways to evaluate events and outcomes of antivascular therapy. These efforts are in collaboration with laboratories using ultrasound, magnetic resonance, radionuclide and optical techniques to image hemodynamic, cellular and physiological events in tumors and have clinical implications and applications.
