Netrin proteins and their receptors regulate cell and axon migration, and are implicated in tissue morphogenesis, tumorigenesis and angiogenesis. Deregulation of mechanisms that control cell motility plays a key role in tumor progression by promoting tumor cell dissemination. Unwanted neovascularization also contributes to tumor progression and metastasis and to ocular diseases which are a leading cause of blindness. Here, we describe novel netrin-derived polypeptides and fragments or derivatives thereof that selectively inhibit cell growth, migration or branching. Methods and compositions for the treatment and prevention of conditions involving cell migration or neovascularization, such as cancer and ocular disease, are also provided.
