DNA methylation was the first discovered epigenetic mark and is the most widely studied topic in epigenetics. In vivo, DNA is methylated following DNA replication and is involved in a number of biological processes including the regulation of imprinted genes, X chromosome inactivation. and tumor suppressor gene silencing in cancer cells. Methylation often occurs in cytosine-guanine rich regions of DNA (CpG islands), which are commonly upstream of promoter regions.

    5-methylcytosine (5-mC) has been known for a long time as the only modification of DNA for epigenetic regulation. In 2009, however, Kriaucionis discovered a second methylated cytosine, 5-hydroxymethylcytosine (5-hmC). The so-called 6th base, is generated by enzymatic conversion of 5-methylcytosine (5-mC) into 5-hydroxymethylcytosine by the TET family of oxygenases. Early reports suggested that 5-hmC may represent an intermediate of active demethylation in a new pathway which demethylates DNA, converting 5-mC to cytosine. Recent evidence fuel this hypothesis suggesting that further oxidation of the hydroxymethyl group leads to a formyl or carboxyl group followed by either deformylation or decarboxylation. The formyl and carboxyl groups of 5-formylcytosine (5-fC) and 5-carboxylcytosine (5-caC) could be enzymatically removed without excision of the base.


Main DNA methylation technologies

Overview of the three main approaches for studying DNA methylation.

  1. Chemical modification with bisulfite – Bisulfite conversion
  2. Enrichment of methylated DNA (including MeDIP and MBD)
  3. Treatment with methylation-sensitive or dependent restriction enzymes

 

Description Features
Bisulfite conversion Chemical conversion of unmethylated cytosine to uracil. Methylated cytosines are protected from this conversion allowing to determine DNA methylation at single nucleotide resolution.
  • Single nucleotide resolution
  • Quantitative analysis - methylation rate (%)
  • Gold standard and well studied
  • Compatible with automation
Methylated DNA enrichment (Hydroxy-)Methylated DNA is enriched by using specific antibodies (hMeDIP or MeDIP) or proteins (MBD) that specifically bind methylated CpG sites in fragmented genomic DNA.
  • Resolution depends on the fragment size of the enriched methylated DNA (300 bp)
  • Qualitative analysis
  • Compatible with automation
Restriction enzyme-based digestion Use of (hydroxy)methylation-sensitive or (hydroxy)methylation-dependent restriction enzymes for DNA methylation analysis at specific sites.
  • Determination of methylation status is limited by the enzyme recognition site
  • Easy to use
