A study in humans identified 197 miRNAs associated with wound healing, burn wound healing, and scarring, with specific miRNAs showing altered expression in burned skin, hypertrophic scar tissue, and various wound types [Siu et al. DOI:10.1111/wrr.13100]. A study in humans demonstrated that the mir-4785 was identified as a high diagnostic performance circulating microRNA for acute myocardial infarction, exhibiting robust diagnostic performance in plasma [Wang et al. DOI:10.1186/s40364-024-00690-x].
