AbstractAim: To study the epigenetic alternations and biological functions of ZFP82 in esophageal squamous cell carcinoma. Materials & methods: Analysis of ZFP82 expression was carried out by quantitative real-time PCR. Cell function was tested by MTS cell proliferation assay, transwell assay and flow cytometry. Gene mechanisms were studied by Reverse Transcription-Polymerase Chain Reaction (RT-PCR), quantitative real-time PCR, luciferase reporter assay and Western blot.Results:ZFP82 promoter methylation was downregulated in esophageal squamous cell carcinoma. ZFP82 ectopic expression suppressed cell function and regulated NF-κB phosphorylation and genes involved in cell cycle arrest and apoptosis. Moreover, ZFP82 methylation was correlated with age, tumor stage and outcome. Conclusion:ZFP82 is a tumor suppressor and is disrupted by promoter CpG methylation during esophageal carcinogenesis.
