Clinical significance and research progress of DNA methylation in glioma

Ying⁃ying YAO, Lei⁃ming WANG, Liang⁃hong TENG

Abstract


Glioma has a specific CpG island methylator phenotype (G⁃CIMP), which is closely related to isocitrate dehydrogenase (IDH) mutation. A hypermutation is present at recurrence in temozolomide⁃treated gliomas, and O6⁃methylguanine⁃DNA methyltransferase (MGMT) promoter methylation levels can help predict the risk of hypermutation to inform clinical decision. Whole genome DNA methylation analysis has become an effective auxiliary method for the classification of central nervous system tumors. This article reviews the research progress of DNA methylation analysis in glioma and discusses its clinical significance.
