Abstract
To determine the clinical significance of gene promoter methylation in esophageal squamous cell carcinoma (ESCC), we examined the promoter methylation status of genes showing elevated expression, as determined by DNA microarray-based transcriptomic analysis, in three ESCC cell lines (TE-1, TE-2, TE-10) after 5-aza-2'-deoxycytidine (DAC) treatment. We observed a high degree of DNA methylation within the promoter regions of three genes, namely cathepsin L2 (CTSL2), normal mucosa of esophagus specific 1 (NMES1), and fatty acid binding protein 5 (FABP5). Overexpression of NMES1 in ESCC cell lines increased cell motility. Down-regulation of NMES1 might play an important role in the cell motility of ESCC or be a potent marker of malignancy.Entities:
