A review of human studies identified 197 miRNAs associated with wound healing, burn wound healing, and scarring, with specific expression patterns in human skin tissue and cells post-burn and in hypertrophic scar tissue [Siu et al. DOI:10.1111/wrr.13100]. A study in humans demonstrated that the miR-553 is involved in drug response, with its expression increased by chronic intermittent alcohol exposure in the brain [Zhao et al. DOI:10.1007/s11411-016-9671-z].
