| Research Abstract |
The aim of this study was to profile methylation changes and identify methylated genes and to clarify the role of genome-wide hypomethylation in esophageal squamous cell carcinoma(ESCC).The degree of genome-wide CpG islands methylation increased from the normal healthy epithelium,through the ESCC-background non-neoplastic epithelium,to the carcinoma tissues.CpG island hypermethylation of tumor-related genes,especially that of the LRFN5 gene,and genome-wide hypomethylation appear to play important roles in ESCC pathogenesis irrespective of drinking and/or smoking habits.
