Research Abstract

We aimed to analyze epigenome alterations in gastrointestinal cancer cells,cancerstroma and background non-cancerous mucosa. By performing Methylated CpG Amplification (MCA)-microarray analysis and bisulfite-pyrosequencing analysis, we detected methylationof tumor-related genes, such as SFRP1 and miR-34b/c, in gastric cancer cells as well as cancer stroma. Moreover, we identified aberrant methylation of a candidate cancer-related gene, RASGRF1, in both gastric cancer cells and background non-cancerous mucosa. We also found that methylationof RASGRF1 could be a potential biomarker to assess gastric cancer risk.
