The Department of Radiation Oncology is in the new Perelman Center. Occupying approximately 80,000 square feet on the Concourse Level, the new treatment facilities includes the most advanced proton and conventional radiation treatment modalities available as well as public spaces designed for the highest levels of patient comfort.

macrophage transition, metabolic dysfunction, translational control, brain tumor, and lung
cancer.

Description of Research
Tumors have been recognized as organ-like tissues of extreme complexity. Stromal cells,
extracellular matrix, and soluble factors constitute the microenvironment that fuels tumor
progression and fosters therapeutic resistance. Overgrown, topologically and structurally
abnormal blood vessels characterize the microenvironment of most highly malignant solid
tumors including brain tumor and lung cancer. The newly formed vasculature creates an
aberrant “vascular niche” that regulates the proliferation, apoptosis, differentiation, and
migration of tumor cells, cancer stem cells, and immune cells. Our studies focus on the
interaction of vascular endothelial cells with cancer stem cells and immune cells, which
promotes tumor progression, induces therapeutic resistance, and protects tumor from host
immunity. We employ various approaches and methods of biochemistry and biophysics,
molecular and cellular biology, and genetics of vertebrate models including zebrafish and
mouse, to dissect the convergent and divergent regulatory pathways. The long-term objective
of our laboratory is to identify the key mechanisms that control vascular niche-mediated
cancer development, as well as to develop new vasculotherapies for the treatment of brain
tumor and lung cancer.
Main research area includes (1) Vascular abnormity mediated by endothelial-mesenchymal
transition, (2) Vascular niche for the maintenance of stemness in cancer stem cells, (3)
Translational control in cancer stem cells, and (4) Metabolic dysfunction in tumor-associated
endothelial cells.
