Tumor blood vessels are a key target for cancer therapeutic management. Tumor cells secrete high levels of pro-angiogenic factors which contribute to the creation of an abnormal vascular network characterized by disorganized, immature and permeable blood vessels, resulting in poorly perfused tumors. The hypoxic microenvironment created by impaired tumor perfusion can promote the selection of more...
Both neuronal and vascular development require guidance to establish a precise branching pattern of these systems in the vertebrate body. Several molecules implicated in axon navigation have also been shown to regulate vessel sprouting. Among these guidance cues, Netrins constitute a family of diffusible molecules with a bifuncional role in axon pathfinding. Recent findings implicate Netrins in other...
