Advances in effect of Semaphorin family and their receptors on tumor angiogenesis

Semaphorin family plays an important role in the development of nervous system axonal guidance. Recently, many reports have shown that these molecules not only affect the rejection and attraction of neurons, but also regulate cell proliferation, adhesion and migration. More importantly, they also play an important role in tumor growth, migration, immune response and tumor angiogenesis which is of great importance in tumor occurrence, development and prognosis. Now, antiangiogenic therapy has become a new method for tumor treatment. However, it still has some limitations and shortcomings. Therefore, it is necessary to fully understand the regulation mechanism of tumor angiogenesis, thus we can provide theoretical basis and clinical evidence for antiangiogenic therapy. Following is a review of Semaphorin and their receptors acting as regulators in tumor angiogenesis.
