Advances in Epigenetics suggested that DNA methylation profiling, plays an important role in various biological process such as silencing, maintaining or expression of genomic stability. DNA methylation is the most comprehensively studied epigenetic mark, and it involves the addition of a methyl group to the 5′ cytosine of CG dinucleotide, referred to as CpGs. DNA methylation is related to gene regulation and cell differentiation by affecting transcription factor binding sites, insulator components, and chromosome morphology. Recent advances suggested that DNA methylation markers not only can provide information about tissue of origin of evidence sample, but also can rely information about the age and lifestyle or environmental exposure of an individual, for an unknown suspect. In this review, we will be discussing age-associated DNA methylation in various tissues, blood and semen and the applicability of the DNA methylation-based age prediction method to the forensic investigations.
