Targeting VEGF signaling for tumor microenvironment remodeling and metastasis inhibition: Therapeutic strategies and insights

The tumor microenvironment (TME) plays a pivotal role in cancer progression and metastasis, with vascular endothelial growth factor (VEGF) signaling serving as a key regulator of tumor angiogenesis and immune evasion. VEGF induces abnormal blood vessel formation, promoting tumor growth, immune suppression, and metastasis through epithelialmesenchymal transition (EMT). As a result, VEGF signaling has become a critical therapeutic target in cancer treatment. This review examines the molecular mechanisms driving VEGF-mediated tumor growth and angiogenesis, with a focus on the interaction between tumor and endothelial cells and the dual role of VEGF in fostering vascularization and immune suppression.
