EGFR and PDGFRA co-expression and heterodimerization in glioblastoma tumor sphere lines
Abstract Concurrent amplifications of EGFR and PDGFRA have been reported in up to 5% of glioblastoma (GBM) and it remains unclear why such independent amplification events, and associated receptor overexpression, would be adaptive during glioma evolution.Here, we document that EGFR and PDGFRA protein co-expression occurs in 37% of GBM.There is wide
