  •   Objective  To investigate the expression of Livin protein and epithelial-mesenchymal transformation (EMT)-related proteins Vimentin and E-cadherin in oral squamous cell carcinoma (OSCC) tissues, and to explore the correlation and clinical significance of the three protein expressions.  Methods  EliVision method of immunohistochemical was used to examine the expression of Livin, Vimentin and E-cadherin in 56 cases of OSCC and 56 cases of paracancerous tissues. The correlation between the expression of Livin, Vimentin and E-cadherin and the clinicopathological features of OSCC patients was analyzed. Furthermore, western blot was used to examine the expression of Livin, Vimentin and E-cadherin in 10 fresh OSCC tissues.  Results  The positive rate of Livin in OSCC tissues was 67.9%, which was significantly higher than that in paracancerous tissues (16.1%), and the expression of Livin was related to lymph node metastasis and TNM stage of OSCC. The positive rates of E-cadherin and Vimentin in OSCC tissues were 44.6% and 50%, respectively. Livin was negatively correlated with the expression of E-cadherin and positively correlated with the expression of Vimentin. The results of western blot showed that in the OSCC tissues with high expression of Livin, the expression of E-cadherin was low and Vimentin was high.  Conclusion  The expression of Livin can promote the invasion and metastasis of OSCC, which may be achieved by activating the occurrence of EMT by expressing Livin.
