In malignant tumors such as lung cancer, the relationship between the Notch pathway and vascular endothelial growth factor (VEGF) is particularly close.Jagged1, as a ligand of the Notch pathway, can significantly upregulate the expression of VEGF and promote tumor neovascularization upon binding to Notch1, which in turn promotes tumor proliferation and metastasis (60). This evidence concerns the gene VEGFA and lung carcinoma.
