Background & Objective:
Esophageal squamous cell carcinoma (ESCC) is one of the world's deadliest cancer diseases. Deregulation of developmental signaling pathways such as Wnt/β-catenin is frequently implicated in a wide range of human cancers. The present study was designed to analyze the expression of the Pygopus2 (PYGO2) protein, the main co-activator of the Wnt/β-catenin signaling pathway, in ESCC tissues and evaluate its probable correlation with clinicopathological features of patients.
Methods:
In this study, PYGO2 protein expression was assessed in tumors and margin normal tissues from 50 ESCC patients using immunohistochemical analysis, and its clinicopathological relevance in the patients was evaluated.
Results:
A significant PYGO2 overexpression was observed in %32 of the tumor cells. Interestingly, PYGO2 expression was significantly correlated with the depth of tumor invasion (P= 0.021).
Conclusion:
PYGO2 protein may be highly expressed in ESCC in correlation with the invasiveness of the disease. Therefore, it may be used as a biomarker for diagnosis of invasive ESCC and a putative therapeutic target to inhibit ESCC invasiveness.
