DNA methylation is a biological process by which methyl groups are added to the DNA molecule. Methylation can change the activity of a DNA segment without...

guanine in the DNA sequence). In mammals, DNA methylation is common in body cells, and methylation of CpG sites seems to be the default. Human DNA has about...

such changes are DNA methylation and histone modification, each of which alters how genes are expressed without altering the underlying DNA sequence. Further...

the use of bisulfite treatment of DNA before routine sequencing to determine the pattern of methylation. DNA methylation was the first discovered epigenetic...

biochemistry, the DNA methyltransferase (DNA MTase, DNMT) family of enzymes catalyze the transfer of a methyl group to DNA. DNA methylation serves a wide...

changes to the function of the genome. The human epigenome, including DNA methylation and histone modification, is maintained through cell division (both...

DNA methylation in cancer plays a variety of roles, helping to change the healthy cells by regulation of gene expression to a cancer cells or a diseased...

methylation patterns in the DNA. Physical exercise is one such factor that also has been shown to affect methylation and chromatin modifications. DNA...

reprogramming refers to erasure and remodeling of epigenetic marks, such as DNA methylation, during mammalian development or in cell culture. Such control is also...

enhancers. The binding of EGR1 to its target DNA binding site is insensitive to cytosine methylation in the DNA. While only small amounts of EGR1 transcription...

process called DNA methylation. The enzyme is encoded in humans by the DNMT3A gene. This enzyme is responsible for de novo DNA methylation. Such function...

One current hypothesis for how DNA methylation contributes to the storage of memories is that dynamic DNA methylation changes occur temporally to activate...
