C4.4A as a biomarker of head and neck squamous cell carcinoma and correlated with epithelial mesenchymal transition.

ABSTRACT: C4.4A, a member of the Ly6/uPAR family of membrane proteins, has been identified as a metastasis-associated molecule, but little is known about its actual expression and possible function in head and neck squamous cell carcinoma (HNSCC). To explore diagnostic and prognostic roles of C4.4A in HNSCC, we investigated the expression of C4.4A in human HNSCC tissue array which contains 43 HNSCC, 6 epithelial dysplasia and 16 normal oral mucosa. Expression of C4.4A was significantly increased in epithelial dysplasia and HNSCC when compared with normal oral mucosa. Moreover, high C4.4A expression indicated a rather poor prognosis of HNSCC patients. To better understand the function of C4.4A in HNSCC progression, we investigated epithelial to mesenchymal transition (EMT) associated proteins includi
