A review of human studies identified 197 miRNAs associated with wound healing, burn wound healing, and scarring, with the miR-1298-5p being downregulated in venous ulcers compared to normal skin and acute wounds [Siu et al. DOI:10.1111/wrr.13100]. In a separate forensic investigation, exosomal miRNA expression profiling in postmortem human serum from acute myocardial infarction (AMI) cadavers demonstrated that the miR-1298-5p was significantly downregulated (3.29-fold) compared to control cases [Kanno et al. DOI:10.1007/S00414-022-02913-Y].
