Abstract
Cancer remains one of the leading causes of death worldwide and poses a significant challenge to effective treatment due to its complexity. Angiogenesis, the formation of new blood vessels, is a critical process in tumor growth and metastasis. The VEGF/VEGFR pathway plays a crucial role in regulating angiogenesis. Many anti-angiogenesis agents, including monoclonal antibodies and tyrosine kinase inhibitors, have been investigated for the treatment of various cancers. However, they face significant limitations such as limited bioavailability and drug resistance. Nanoparticles have emerged as a promising tool for effective drug delivery while minimizing systemic side effects. This review explores the application of nanoparticles dedicated to angiogenesis-targeted cancer therapy, particularly targeting the VEGF/VEGFR pathway. We describe drug delivery systems based on inorganic, lipid, and polymeric nanoparticles. Moreover, special attention is given to functionalized nanoparticles, which can precisely target numerous proteins that are significantly overexpressed on the surfaces of endothelial cells, tumors, or other cells in the tumor microenvironment. We summarize a series of nanoparticles designed for selective targeting of tumor vasculature, emphasizing the challenges faced by anti-angiogenic cancer therapies.
