The UT Southwestern scientists also discovered that Rasip1 and a protein binding partner are both required for blood vessels to form channels through which blood can flow, she said.
Most approaches to therapies aimed at blocking blood vessel formation have focused on growth factors that occur outside the cell rather than intrinsic cellular growth factors like Rasip1, Dr. Cleaver said.
"Although this is still a mouse study, we feel that future studies of Rasip1 and the molecular processes under its control hold great promise to provide tools and models for advancing clinical therapies aimed at blocking vessel formation in tumors," she said.
The researchers now plan to look for drugs that block Rasip1 in order to eventually develop strategies to stop the growth of functional blood vessels and starve cancerous tumors, she said.
