N2 - Purpose: To determine the involvement of ZIC2 in oral squamous cell carcinoma (OSCC). Methods: ZIC2 mRNA and protein expression in primary OSCCs (n = 74), oral premalignant lesions (OPLs, n = 20) and five OSCC-derived cell lines (HSC-2, HSC-3, OK-92, H1, and Sa3) were analyzed by quantitative reverse transcriptase-polymerase chain reaction, Western blot and immunohistochemistry (IHC). In addition, we evaluated the correlation between ZIC2 IHC scores in OSCCs and the clinicopathologic status. Results: Significant up-regulation of ZIC2 was detected in OSCC-derived cell lines (P < 0.05), primary OSCCs (P < 0.05) and OPLs (P < 0.05) compared with normal counterparts. Among the clinical variables analyzed, ZIC2 expression was associated with the histopathologic types of OSCC. Furthermore, the survival rates differed significantly between ZIC2-positive cases and ZIC2-negative cases. Conclusions: These results suggested that ZIC2 expression is correlated with the differentiation type of OSCC and diagnosis and might be a potential prognostic indicator and therapeutic target for OSCCs.
