Research Abstract

The methylation level at IGF2 DMR0 is correlated with IGF2 LOI and is a suggested surrogate marker for IGF2 LOI.The IGF2 imprinting status was screened using ApaI polymorphism, and IGF2 protein expression was evaluated by immunohistochemistry with 30 esophageal squamous cell carcinoma tissue specimens. For survival analysis, IGF2 DMR0 methylation was measured using a bisulfite pyrosequencing assay with 216 ESCC tissue specimens. IGF2 LOI cases exhibited lower DMR0 methylation levels than IGF2 non-LOI cases. Among 202 patients eligible for survival analysis,IGF2 DMR0 hypomethylation was significantly associated with higher cancer-specific mortality. The IGF2 DMR0 methylation level in ESCC was associated with IGF2 LOI and IGF2 protein expression.In addition, IGF2 DMR0 hypomethylation was associated with a shorter survival time, suggesting its potential role as a prognostic biomarker.
