- DNA_methylation abstract "DNA methylation is a biochemical process whereby a methyl group is added to the cytosine or adenine DNA nucleotides. The rate of cytosine DNA methylation differs strongly between species, e.g. absolute quantification by mass spectrometry revealed 14% of cytosines methylated in Arabidopsis thaliana, 8% in Mus musculus, 2.3% in Escherichia coli, 0.03% in Drosophila, and virtually none (< 0,0002%) in yeast species.DNA methylation may stably alter the expression of genes in cells when 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 becoming a different cell type. DNA methylation is typically removed during zygote formation and re-established through successive cell divisions during development. Some methylation modifications that regulate gene expression are heritable and cause genomic imprinting, and hydroxylation of methyl groups occurs rather than complete removal of methyl groups in zygote.DNA methylation suppresses the expression of endogenous retroviral genes and other harmful stretches of DNA that have entered the host genome. 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.".
