ABSTRACT
[Objective] To investigate the far-upstream element (FUSE) binding protein 1 (FUBP1) expression in tongue squamous cell carcinoma (TSCC) and its adjacent normal tissues,to explore the role of FUBP1 in the initiation and development of TSCC and its clinical significance.[Methods] FUBP1 expression in TSCC tissues and its adjacent normal tissues was detected by immunohistochemistry,qRT-PCR and Western blot respectively.Statistical analysis was used to analyze the relationship between FUBP1 expression and clinical pathological parameters and prognosis.[Results] FUBP1 expression in TSCC tissues was higher than that in the corresponding adjacent normal tissues (P＜0.05);FUBP1 expression in TSCC tissues was higher in patients of advanced stage and with cervical lymph node metastasis (P＜0.001);The 5-year survival rate of FUBP1 over expression group was lower than that of FUBP1 low expression group (P=0.035);FUBP1 may be an independent predictor in patients with TSCC.[Conclusion] The high expression of FUBP1 in TSCC tissues is associated with poor prognosis in patients with TSCC,therefore,high expression of FUBP1 may promote the formation and development of TSCC,and become a index for prognosis in TSCC patients.
