A study in humans identified hsa-miR-145 as a saliva-specific microRNA marker for forensic body fluid identification, demonstrating its high overexpression in saliva compared to other fluids with an area under the ROC curve of 0.97, indicating high diagnostic accuracy [Park et al. DOI:10.1002/elps.201400075]. A study in humans demonstrated that plasma extracellular vesicles containing the mir-145 were significantly upregulated in patients with acute coronary syndrome who experienced sudden cardiac death compared to healthy controls, and its levels were positively correlated with myoglobin, showing a predictive area under the curve of 0.7778 [Huang et al. DOI:10.1039/D2MO00257D].
