A review of human studies identified 197 miRNAs associated with wound healing, burn wound healing, and scarring, with specific miRNAs showing altered expression in human skin tissue samples post-burn, during healing, and in hypertrophic scar tissue [Siu et al. DOI:10.1111/wrr.13100]. A review of literature indicates that the miR-4262 is altered in the heart by alcohol exposure in experimental models [Mandal et al. DOI:10.1002/Jat.3504].
