Objective The objective of this paper was to study the expression of related protein and Twist transcription factor of epithelial-mesenchymal transition in oral squamous cell carcinoma (OSCC) tissue and the correlations of OSCC and oral squamous cell carcinometastasis. The paper also investigated the clinical significance of expression on OSCC.Methods The labels of epithelium materialization (E-cadherin and cytokeratin), stromal labels (N-cadherin), transcription factor Twist protein, and mRNA expression in 30 OSCC tissues were investigated via immunohistochemistry and in situ hybridization. The paper also conducted contrast analysis with clinicopathology.Results Immunization result showed that the expressions of Twist and N-cadherin in the OSCC group were more significant than those of the normal group (PConclusion Epithelium materialization exists in OSCC tissue. Twist can enhance the invasiveness of tumor cell and promote the infiltration and metastasis of OSCC. The combined detection of Twist, E-cadherin, and N-cadherin expressions can effectively predict and estimate OSCC metastasis.
