A review of human studies identified the mir-539 as being upregulated in burn hypertrophic scar tissue compared to normal skin [Siu et al. DOI:10.1111/wrr.13100]. A study in mice demonstrated that the mir-539 was down-regulated -2.02-fold in the hippocampus at 4 hours after traumatic brain injury under normal temperature conditions, but showed no significant change under low-temperature conditions [Wang et al. DOI:10.1258/ebm.2012.012123]. In a separate study in rats, the mir-539 was identified as one of several microRNAs upregulated 1 day after contusion spinal cord injury [Hu et al. DOI:10.1089/neu.2012.2748].
