A review of human studies identified 197 miRNAs associated with wound healing, burn wound healing, and scarring, with specific dysregulation patterns observed in human skin tissue and cell lines post-burn and in hypertrophic scar tissue [Siu et al. DOI:10.1111/wrr.13100]. A study in Wistar rats demonstrated that heroin exposure significantly upregulated the miR-32-3p in the ventral tegmental area by 1.50-fold [Pence et al. DOI:10.1007/S00221-024-06972-Y].
