The role of DNA methylation
The covalent addition of a methyl-group at the 5-carbon of cytosine in DNA, resulting in 5-methylcytosine (5-mC), is an epigenetic mark that influences gene expression, cell differentiation and embryonic development. DNA methyltransferase (DNMT) enzymes catalyze the process. The global methylation pattern in mammals is rather homogenous. However, the CpG islands, which are the main sites for methylation, tend to be near transcription start sites. Furthermore, the methylation level can differ significantly within one organism based on tissue type and between normal and cancerous cell in the same tissue.
While 5-mC is the most common and widely studied DNA-methylation cytosine methylation and demethylation processes give rise to various other forms. In particular 5-hydroxymethylcytosine (5-hmC) has garnered interest since it has been found to be elevated in certain mammalian tissues, such as human and mouse brain, as well as in embryonic stem cells. It is thought to determine developmental fates and, when present in aberrant patterns, contributes to disease. A complete understanding of the potential function 5-hmC requires an accurate, scalable sequencing method.
Assays to study DNA methylation
Traditionally, 5-mC sites are identified by bisulfite sequencing or methylated CpG island recovery assay (MIRA). These techniques however cannot distinguish between 5-mC and 5-hmC. TAB-seq (Tet-assisted bisulfite sequencing of 5-hydroxymethylcytosine) is a modification of the standard bisulfite sequencing method through which 5-hydroxymethylcytosine (5-hmC) can be specifically identified. In conjunction with the traditional methods TAB-seq allows mapping of both methylation variants at single-base resolution either on a genomic scale or for a particular locus. TAB-seq was first introduced in 2012. Until now it has been used to study the role of 5-hmC in brain functions, cancers and several cognitive disorders.
Methylated DNA immunoprecipitation (MeDIP) and hydroxylmethylated DNA immunoprecipitation (hMeDIP) on the other hand are two methods that take advantage of 5-mC- and 5-hmC-specific antibodies respectively to enrich DNA fragments bearing these modifications.
