VEGFB and cancer: To identify all VEGF/VEGFR subunits expression among human malignancies, we collected and analyzed three VEGF ligands (VEGFA, VEGFB, and VEGFC) and three VEGF receptors (VEGFR1/FLT1, VEGFR2/KDR, and VEGFR3/FLT4) gene expression profiles in 1024 human cancers caused by 24 tumor types in the Cancer Cell Line Encyclopedia (CCLE).
