Abstract
Methylation of cytosine in DNA has long been known as an important mechanism of transcriptional regulation. While DNA methyltransferases have been well characterized, the existence of enzymes involved in cytosine demethylation has been questioned. However, in the past few years, through a convergence of biochemical and genetic studies, active DNA demethylation has been finally recognized as an important mechanism of epigenetic regulation. Here, we will review the biological processes that rely on active DNA demethylation, the relevant DNA demethylating activities, and the corresponding biochemical pathways. We will then describe the role of DNA demethylating factors in development and their alterations in human disease and cancer.
