The increase in EGFR, Src and AnxA2 levels upon Her-2 downregulation and inhibition led us to investigate the role of AnxA2 in EGFR signaling in TNBC subset of breast cancer, where EGFR plays a major role in survival, growth, migration and invasion of cancer cells [15], [16], [46], [47]. The gene discussed is ERBB2; the disease is breast carcinoma.
