In oral squamous cell carcinoma, overexpression of carcinoembryonic antigen-related cell adhesion molecule 6 (CEACAM6) also potentiates the EGF-induced EGFR phosphorylation, activation of the MAPK and Akt signaling pathways, and cell migration [93]. The gene discussed is CEACAM6; the disease is oral cavity squamous cell carcinoma.
