To understand the underlying molecular pathogenesis of glioblastoma, The Cancer Genome Atlas (TCGA) studied 206 glioblastoma samples using microarray technology and the analyses identified three core signal pathways implicated in glioblastoma, including receptor tyrosine kinase (RTK) signaling, and the P53 and RB tumor suppressor pathways [4]. This evidence concerns the gene NTRK1 and glioblastoma.
