A review of RNA markers for forensic body fluid/tissue identification in human samples notes that the mir-5010 is mentioned as a specific marker for venous blood [Liu et al. DOI:10.1007/s00414-025-03656-2]. In a separate human study on myocardial ischemia, the mir-5010 was found to be upregulated (1.86 fold) in postischemic left ventricular samples [Saddic et al. DOI:10.1152/physiolgenomics.00049.2015].
