Background: Transient receptor potential vanilloid 2 (TRPV2) was recently shown to be involved in migrant potentials. The present study aimed to investigate its role in esophageal squamous cell carcinoma (ESCC). Methods: Knockdown experiments were conducted using TRPV2 siRNA in human ESCC cell lines, and anti-tumor effects were analyzed. The gene expression profiles of cells were analyzed using a microarray method. An immunohistochemical staining was performed on 62 primary tumor samples. Results: TRPV2 overexpression was observed in TE15 and KYSE170 cells. TRPV2 depletion suppressed proliferation, cell cycle progression, and invasion/migration ability, and induced apoptosis. A pathway analysis of microarray data showed that TRPV2 depletion down-regulated WNT/beta-catenin signaling-related genes and basal cell carcinoma signaling-related genes. The suppression of tumor functions, such as proliferation, invasion, and angiogenesis, was predicted in the ontology analysis. Immunohistochemical analysis revealed a correlation between strong TRPV2 expression and a poor prognosis in ESCC patients. Conclusion: The present results suggest that TRPV2 regulates cancer progression by affecting WNT/beta-catenin or basal cell carcinoma signaling, and that TRPV2 strong expression is associated with a worse prognosis in ESCC patients. These results provide an insight into the role of TRPV2 as a novel therapeutic target or biomarker for ESCC.
