The precise regulation of DNA methylation is essential for normal cognitive function. Indeed, when DNA methylation is altered as a result of developmental mutations or environmental risk factors, such as drug exposure and neural injury, mental impairment is a common side effect. The investigation ...
In the mammalian genome, DNA methylation is an epigenetic mechanism involving the transfer of a methyl group onto the C5 position of the cytosine to form 5-methylcytosine. DNA methylation regulates gene expression by recruiting proteins involved in gene
DNA methylation is a stable yet reversible epigenetic modification that regulates gene expression. New technologies have provided deep insights into the distribution and function of DNA methylation in humans, including the Human Roadmap Epigenome Project that defined genomewide methylation profiles across ...

Deoxyribonucleic acid (DNA) is a molecule made up of two polynucleotide chains that coil around each other to form a double helix and carry genetic instructions for all known organisms and viruses' development, function, growth, and reproduction.Nucleic acids include DNA and ribonucleic acid (RNA)...

An important function of DNA methylation is to protect the genomic integrity by silencing transposable elements and ensure genomic stability. Although DNA methylation patterns are transmitted from cell to cell during cell division, they are not permanent. DNA methylation patterns can change throughout ...
