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 rats demonstrated that the mir-325 was identified as a biomarker of acute myocardial ischemia (AMI) via LASSO regression, with the panel of key miRNAs achieving an area under the curve (AUC) of 75% in ROC analysis [Zhao et al. DOI: 10.3390/cimb47110889]. In a separate investigation in rats, the mir-325 was found to be downregulated in the infralimbic prefrontal cortex after a 4-week abstinence from escalated cocaine intake [Kumaresan et al. DOI: 10.3390/Biomedicines11051368].
