In a new study by Masanobu Komatsu, Ph.D., associate professor in the Cardiovascular Pathobiology Program and Tumor Microenvironment and Metastasis Programs, a cellular protein called R-Ras was found to suppress the effects of vascular endothelial growth factor (VEGF), a signaling molecule that helps create new blood vessels and is overexpressed in many tumors. The findings create a new route to treat cancer as well as certain causes of blindness and ischemic diseases.
