ERBB2 and breast cancer: In contrast, pathway models trained with CCLE data successfully identified a few top pathways involving both ERBB2 and EGFR, including “anti-apoptotic action of ErbB2 in breast cancer” (see Additional file 5), “ERBB family signaling”, “mitogenic action of ErbB2 in breast cancer” and “EGFR signalling via small GTPase”.
