A study in humans demonstrated that the mir-4644 increased 3.23-fold in serum following recreational alcohol consumption, with this change being part of a broader significant increase in 265 microRNAs [Ten Berg et al. DOI:10.1080/1354750X.2018.1499128]. In forensic body fluid identification research, the mir-4644 was identified as a microRNA with potential for alcohol exposure detection, though its specific performance in differentiating body fluids was not detailed in the examined validation framework for venous blood, saliva, semen, vaginal secretion, and menstrual blood [Sauer et al. DOI:10.1016/j.fsigen.2016.01.018].
