Ras pathway activation in gliomas: a strategic target for intranasal administration of perillyl alcohol

Abstract
Introduction:  Targeted therapy directed at restricted molecular alterations is already creating a commove in the act of cancer patients.
Malignant gliomas commonly overexpress the oncogenes EGFR and PDGFR and allow mutations and deletions of the ontogeny sequence genes PTEN and TP53. Some of these alterations front to activation of the P13K/Akt and Ras/MAPK pathways, which […]
