Forensic Context

A study in humans demonstrated that the expression profiles of the piR-hsa-8031 collectively exhibited acceptable discriminating ability for most forensically relevant biological samples, including venous blood, menstrual blood, saliva, semen, vaginal secretions, and skin [Wang et al. DOI:10.1016/j.fsigen.2019.07.015]. A study in humans using massively parallel sequencing identified the piR-hsa-8031 as an absolute specific marker for semen, demonstrating high specificity in five out of five pairwise comparisons with other body fluids/tissues and moderate expression [Liu et al. DOI:10.3390/genes13091530].
