A study in humans demonstrated that the miR-191-3p was downregulated 6 hours post-burn in heat-shocked skin epidermal stem cells compared to controls [Siu et al. DOI:10.1111/wrr.13100]. A study in non-human primates (Macaca mulatta) demonstrated that plasma levels of the miR-191-3p above the median at day 15 post whole-thorax lung irradiation were significantly associated with reduced survival, validating its role as a predictive biomarker for late radiation injury [Rogers et al. DOI:10.1667/RADE-20-00031.1].
