Nasopharyngeal carcinoma (NPC) is a unique tumour due to its aetiology, incidence pattern and its consistent association with Epstein-Barr virus (EBV). EBV encodes many viral proteins, which targets crucial cell cycle regulatory proteins. Cadherins are a family of transmembrane glycoproteins, which mediates Ca2+-dependent intercellular adhesion. Epithelial (E)-cadherin is an important member of this family, which is expressed predominantly on the surface of epithelial cells. E-cadherin acts as an invasion/metastasis-suppressor gene, hence knowledge of the molecular mechanism that controls its expression or function is of primary importance in understanding the process of tumor invasion.
