Mechanistically, FGF2 triggers the activation of the FGFR pathway, turns on the activation of VEGFR signaling via the overproduction of VEGF-A, induces the interaction between FGFR1/2 and VEGFR1, and thereby renders cancer cells highly sensitive to the dual inhibition of the aforementioned RTKs. This evidence concerns the gene FGF2 and cancer.
