Preliminary evaluation for Bit1 as a potential biomarker for squamous cell carcinoma and adenocarcinoma of esophagus

Mounting evidence has demonstrated that Bit1 has been investigated as an etiological factor for certain cancers, including esophageal squamous cell carcinoma reported in our previous study, but data regarding possible roles of Bit1 in esophageal squamous cell carcinoma and esophageal adenocarcinoma remain to be elucidated. The purpose of this study was to examine whether Bit1 can be a novel diagnostic marker for the patients with esophageal squamous cell carcinoma and esophageal adenocarcinoma. The results revealed that Bit1 level in esophageal squamous cell carcinoma was significantly higher than that in esophageal adenocarcinoma tissues (p 0.05). Bit1 expression patterns were completely in accordance with matrix metalloproteinase 2 and Bcl-2 in esophageal squamous cell carcinoma and esophageal adenocarcinoma. In addition, Bit1, Bcl-2, and matrix metalloproteinas...
