Abstract
Epigenetics deals with the changes in gene expression (no change in the genetic code) concerning certain epigenetic elements in response to the environment. Some of the most common epigenetic examples include DNA methylation, histone modifications, and non-coding RNAs. This field has been extensively applied in forensic studies, particularly to determine types of body fluids, distinguish them from mixed samples, uncovering the biological age of the forensic samples and drug-based studies. Considering recent findings, this review highlights the applications of epigenetics in forensic investigations.
