Various receptor tyrosine kinases (RTK’s) are expressed in medulloblastoma, including vascular endothelial growth factor receptor-2 (VEGFR-2), platelet-derived growth factor receptor α (PDGFRα), hepatocyte growth factor receptor (MET) and epidermal growth factor receptor 2 (ErbB2)[8]. Here, ERBB2 is linked to medulloblastoma.
