Cytosine to 5-hydroxymethylcytosine
Web5-Methylcytosine (5mC) is the most abundant modified nucleotide in eukaryotes, accounting for up to 5% of cytosines in vertebrates. Detecting cytosine DNA methylation remained a challenge until the development of the bisulfite conversion technique in 1970 by Hayatsu (2008) and Hayatsu et al. (1970). 5-Hydroxymethylcytosine (5hmC) is a DNA pyrimidine nitrogen base derived from cytosine. It is potentially important in epigenetics, because the hydroxymethyl group on the cytosine can possibly switch a gene on and off. It was first seen in bacteriophages in 1952. However, in 2009 it was found to be … See more Every mammalian cell seems to contain 5-Hydroxymethylcytosine, but the levels vary significantly depending on the cell type. The highest levels are found in neuronal cells of the central nervous system. The amount of … See more The exact function of this nitrogen base is still not fully elucidated, but it is thought that it may regulate gene expression or prompt DNA demethylation.
