Activated BRAF induces gliomas in mice when combined with Ink4a/Arf loss or Akt activation
Mutations in receptor tyrosine kinase (RTK) growth factor receptors ( epidermal growth factor receptor , platelet-derived growth factor receptor , MET and ERBB2) , which result in downstream activation of the RAS/RAF/MEK/ERK mitogen-activated protein kinase (MAPK) pathway and PI(3)K/Akt pathway, are...

In addition, BRAF is mutated in the majority of low-grade gliomas and its expression and activity is significantly increased in the majority of high-grade gliomas.
