| Research Abstract |
Molecular mechanisms of methylation induction and its inducing factors are still unclear. We showed that the increased methylation of scattered CpG sites could lead to dense methylation of an entire CGI, and could methylate even genes with high expression. We also showed that specific genes were methylated in gastric mucosae with Helicobacter pylori (H.pylori) infection, and that low gene transcription is an important factor to determine the specificity. Using the Mongolian gerbil model, we showed that the types of inflammations are important for induction of aberrant DNA methylation.
