Identification of DNA methylation abnormality in cancers and other disorders
It is known that various mutations and aberrant DNA methylation are accumulated in cancer cells. Recently, we revealed that aberrant DNA methylation of a specific gene can also be present in a large fraction of cells even in non-cancerous tissues, and that many genes are methylated in a single cancer cell.
In our laboratory, we revealed genes methylated in
- gastric cancers
- esophageal cancers
- colon cancers
- breast cancers
- prostate cancers
- malignant melanomas
In addition, we also revealed that specific genes are inactivated by aberrant DNA methylation in gastric glands with intestinal metaplasia , which is a disorder of cellular differentiation with a polyclonal origin.
