WebJul 2, 2024 · DNA methylation is the common epigenetic aberration. The methylation of 5-position of cytosine bases at CpG dinucleotides such as 5-methylcytosine is well known [8, 9]. CpG islands in promoter regions are basically unmethylated, and expression of the gene is regulated by histone modification. WebIn the mammalian genome, DNA methylation is an epigenetic mechanism involving the transfer of a methyl group onto the C5 position of the cytosine to form 5-methylcytosine. …
