Therefore, VEGF is a candidate to be blocked and controlled and to prevent the activation of the androgen receptor (AR)/phosphatidylinositol 4-phosphate 5-kinase type-1 alpha (PIP5K1α)/AKT/MMP-9/VEGF signaling axis required for cell survival and invasion of metastatic tumors (198). Here, AR is linked to metastatic neoplasm.
