DNA methylation
DNA methylation is a process by which methyl groups are added to DNA. Methylation modifies the function of the DNA, typically acting to suppress gene transcription. DNA methylation is essential for normal development and is associated with a number of key processes including genomic imprinting, X-chromosome inactivation, suppression of repetitive elements, and carcinogenesis.Two of DNA's four nucleotides, cytosine and adenine, can be methylated. Adenine methylation is restricted to prokaryotes.The rate of cytosine DNA methylation differs strongly between species: 14% of cytosines are methylated in Arabidopsis thaliana, 4% in Mus musculus, 2.3% in Escherichia coli, 0.03% in Drosophila, and virtually none (< 0.0002%) in yeast species.DNA methylation can stably alter the expression of genes in cells as cells divide and differentiate from embryonic stem cells into specific tissues. The resulting change is normally permanent and unidirectional, preventing a cell from reverting to a stem cell or converting into a different cell type. However, DNA methylation can be removed either passively, by dilution as cells divide, or by a faster, active, process. The latter process occurs via hydroxylation of the methyl groups that are to be removed, rather than by complete removal of methyl groups. DNA methylation is typically removed during zygote formation and re-established through successive cell divisions during development. Methylation modifications that regulate gene expression are usually heritable through mitotic cell division; some methylation is also heritable through the specialized meiotic cell division that creates egg and sperm cells, resulting in genomic imprinting. DNA methylation suppresses the expression of endogenous retroviral genes and other harmful stretches of DNA that have been incorporated into the host genome over time. DNA methylation also forms the basis of chromatin structure, which enables a single cell to grow into multiple organs or perform multiple functions. DNA methylation also plays a crucial role in the development of nearly all types of cancer.DNA methylation at the 5 position of cytosine has the specific effect of reducing gene expression and has been found in every vertebrate examined. In adult somatic cells (cells in the body, not used for reproduction), DNA methylation typically occurs in a CpG dinucleotide context; non-CpG methylation is prevalent in embryonic stem cells, and has also been indicated in neural development.
