A review of human studies identified 197 miRNAs associated with wound healing, burn wound healing, and scarring, with specific expression patterns validated in human skin tissue samples and cell lines using qRT-PCR, microarrays, and next-generation sequencing [Siu et al. DOI:10.1111/wrr.13100]. A study in mice demonstrated that the miR-337-5p is upregulated in serum at 3 hours post-mild traumatic brain injury across injury severities [Martinez & Peplow DOI:10.4103/1673-5374.219025]. Separate research in mice showed that the miR-337-5p is also upregulated in liver tissue 14 days after whole-body ionizing radiation exposure [Lu et al. DOI:10.1002/cbin.10627].
