DNA Methylation as a Biomarker for Body Fluid. 51 days Journal of Forensic Sciences Read Simultaneous Quantitative Determination of Amphetamines, Opiates, Ketamine, Cocaine and Metabolites in Human Hair: Application to Forensic Cases of Drug Abuse, Age estimation using DNA methylation levels has been widely investigated in recent years because of its potential application in forensic genetics. The main aim of this study was to develop an age predictor model (APM) for blood samples of deceased individuals based in five age‐correlated genes..

Therefore, DNA methylation, which occurs at the 5′-position of cytosine in CpG dinucleotides , has a great potential application for the forensic identification of individuals in an MZ twin pair because individual DNA is uniquely hypo- or hypermethylated (even among MZ twins) based on several factors such environment or disease , . For example DNA hypomethylation, the decrease in global DNA methylation, is likely caused by methyl-deficiency due to a variety of environmental influences and has been proposed as a molecular marker in multiple biological processes such as cancer. The quantification of 5-mC content or global methylation in diseased or environmentally impacted

The bisulfite modified DNA was then amplified via nested PCR using a primer set of which one primer was biotin labeled. Biotinylated PCR products were in turn analyzed and the methylation level at each CpG site was quantitated by pyrosequencing. The percent methylation values at each CpG site were determined and averaged for each tissue type. Epigenetics in forensic science is the application of epigenetics to solving crimes.. Forensic science has been using DNA as evidence since 1984, however this does not give information about any changes in the individual since birth and will not be useful in distinguishing identical siblings. The focus of epigenetics in the forensic field is on non-heritable changes such as aging and diseases.
