Research Abstract |
In the current study, we have analyzed for aberrant DNA methylation which is associated with Helicobacter pylori (H.pylori) induced gastric carcinogenesis. We have shown evidences that both CpG island hypermethylation of cancer-related genes and global hypomethylation occurs in premalignant lesions of diffuse gastric cancer. In addition, through genome-wide screening, we have identified aberrant DNA methylation of novel gastric cancer-related genes and microRNAs. Functional analysis revealed that these are candidate gastric cancer suppressor genes, and DNA methylation analysis in clinical samples suggested that these could be useful risk markers of gastric cancer.
