The tumor contains abundant new vessels, which are unevenly distributed, irregular, and branch-disordered. Angiopoietin (Ang) and tyrosine kinase receptor Tie mediate stable maturation of angiogenesis. Ang1 mainly plays a role in promoting vascular stabilization, and Ang2 is highly expressed in vessels, which makes the structure and function of vessels abnormal. Leaked vessels provide opportunities for invasion and metastasis of circulating tumor cells. Targeting the Ang/Tie axis to correct the abnormal state of vessels and promote its normalization, combined with chemotherapy drugs or immunotherapy, play a synergistic effect against tumors. This article summarizes the role of Ang/Tie axis in tumor angiogenesis and metastasis, and it aims to provide new ideas and strategies for clinical treatment of tumors.
