A study in humans demonstrated that the mir-195 was selected from literature as a potential biomarker for mild traumatic brain injury (mTBI) [Polito et al. DOI:10.1007/s11033-020-05386-7]. A study in mice demonstrated that the mir-195 starts to degrade significantly 24 hours after death in brain, liver, heart muscle, and skeletal muscle, and it was selected as a reference marker for lung tissue in postmortem interval (PMI) estimation [Song et al. DOI:10.1007/s00414-023-03091-1].
