A study in humans identified the miR-3064-5p as upregulated in hypertrophic scar tissue from burn injuries and in heat-shocked skin epidermal stem cells six hours post-burn [Siu et al. DOI:10.1111/wrr.13100], while a separate study in rats predicted the miR-3064-5p as a target binding three heroin-associated circular RNAs in the orbitofrontal cortex following heroin self-administration [Floris et al. DOI:10.3390/ijms23031453].
