[Expression and clinical significance of BTG-1 in 78 patients with oral squamous cell carcinoma].

Purpose: To investigate the expression and clinical significance of B cell translocation gene 1 (BTG1) in oral squamous cell carcinoma(OSCC).

Methods: Immunohistochemical staining was used to detect the expression of BTG1 protein in 78 cases of OSCC tissues, 78 adjacent tissues, 20 normal oral mucosa tissues, and 80 cervical lymph nodes. Western blot and real-time quantitative PCR were used to detect BTG1 protein and mRNA expression levels in 78 OSCC tissues and adjacent tissues.
