ERBB2 and glioblastoma: Only EGFR, phosphorylated EGFRs and ERBB2 (all of them belonging to Erbb family of receptors), as well as catenin-alpha 1 (CTNNA1) were more abundant than SRC_PY416 in EGFR-altered GBM samples compared to unaltered ones, which highlights the link between EGFR and Src signaling pathways in GBM patients.
