A review of human studies identified the miR-212-3p as upregulated six hours post-burn in heat-shocked skin epidermal stem cells compared to controls [Siu et al. DOI:10.1111/wrr.13100]. A study in mice demonstrated that chronic methamphetamine exposure significantly alters microRNA expression in the nucleus accumbens, identifying 45 known METH-responsive miRNAs and two novel candidates [Zhu et al. DOI:10.002/jnr.23605].
