Loss of P16 in Esophageal Adenocarcinoma Detected by Fluorescence in situ Hybridization and Immunohistochemistry

Molecular biology of esophageal adenocarcinoma (EAC) is not fully elucidated. The aim of this study was to assess the expression of cycle regulator and tumor suppressor p16 in esophageal adenocarcinoma. The expression of p16 at protein and gene level was investigated using immunohistochemistry and f...
