Popis: Background Matrix metalloproteinase‐14 (MMP‐14) is known to be a key regulator of oncogenesis and tumor progression. The present study was designed to assess the relationship between the downregulation of MMP‐14 and the in vitro proliferative, migratory, and invasive activity of esophageal squamous cell carcinoma (ESCC) cells. Methods MMP‐14 expression in human ESCC and paracancerous normal esophageal tissue samples was evaluated via immunohistochemistry, and correlations between MMP‐14 staining and patient clinicopathological features were examined. In addition, siRNA was used to knockdown MMP‐14 in ESCC cells, and the proliferation and invasive activity of these cells were then evaluated via MTT and Transwell assays, respectively. Flow cytometry was additionally used to assess cell cycle progression, while Western blotting was employed to measure protein levels within these cells. Results ESCC samples were found to exhibit MMP‐14 overexpression relative to paracancerous tissue samples, and this overexpression was positively correlated with tumor T classification (T1‐2 vs. T3; P
