A study in human myocardial autopsy specimens demonstrated that the miR-98-5p was up-regulated in septic hearts compared to non-septic controls [Pasi Lehto et al. DOI:10.1038/s41598-024-81114-6]. A study in humans demonstrated that the miR-98-5p is up-regulated in myocardial tissue from deceased septic patients compared to non-septic controls [Lehto et al. DOI:10.1038/s41598-024-81114-6], while a separate investigation in humans found it to be differentially expressed in blood samples between individuals within monozygotic twin pairs, suggesting a potential role for distinguishing genetically identical individuals in forensic identification [Xiao et al. DOI:10.1016/j.fsigen.2019.05.003].
