DNA demethylation and epigenetics

Research output: Chapter in Book/Report/Conference proceedingChapter


Epigenetic regulation is essential to gene expression programs necessary for normal embryonic development and maintaining cell functions throughout life. DNA methylation on cytosine nucleotides dictates those gene expression programs. However, the steady state levels and patterns of DNA methylation are maintained through the dynamic balance of DNA methylation and demethylation, and changing either side of the balance will certainly lead to the development of disease. In this chapter, we will briefly discuss recent advances on DNA demethylation and the implications in health and disease.
