title: [The expression and clinical significance of BATF2 in oral tongue squamous cell carcinoma].
abstract: OBJECTIVE
  To investigate the expression and clinical significance of BATF2 in the oral tongue squamous cell carcinoma (OTSCC).
  
  
  METHODS
  Expression of BATF2 mRNA and protein in 16 paired OTSCC tissues and adjacent non-tumor mucosa were examined using quantitative PCR, western blotting analysis and immunohistochemistry assays, and the relation between BATF2 expression and clinical pathologic factor and prognosis was analyzed.
  
  
  RESULTS
  In 16 paired tissues, expression of BATF2 mRNA in 13 OTSCC tissues and expression of BATF2 protein in 14 OTSCC tissues were significantly lower than that in adjacent non-tumor mucosa. In 202 paraffin-embedded OTSCC samples, BATF2 was not expressed in 20 cases (9.9%), low expressed in 104 cases (51.5%) and highly expressed in 78 (38.6%). BATF2 expression level was significantly correlated with histological differentiation (P = 0.002). Patients with low BATF2 expression had significantly poorer overall survival and disease-free survival than those with high BATF2 expression (P < 0.001).
  
  
  CONCLUSIONS
  BATF2 was low expressed in OTSCC and related to tumor differentiation and prognosis and may serve as a prognostic biomarker and potential therapeutic target for this disease.
