Forensic Context

A study in humans demonstrated that the mir-126 exhibits higher expression in blood samples (peripheral and menstrual) compared to other body fluids and was successfully used for body fluid identification within a probabilistic model achieving high prediction accuracy [Li et al. DOI:10.1007/s00414-021-02678-w]. Another study in humans found the mir-126 was down-regulated in denatured dermis from burn patients compared to normal skin, with real-time RT-PCR validation showing a decrease to 0.46-fold [Liang et al. DOI:10.1016/j.burns.2011.10.014]. A study in human skin wound biopsies and HaCaT keratinocytes demonstrated that the mir-126 is upregulated during wound healing and promotes keratinocyte proliferation and migration by directly targeting PLK2 and activating the PI3K/AKT signaling pathway [Chang et al. DOI:10.1002/cbin.11088]. In a separate human study of acute myocardial infarction, plasma levels of the mir-126 were negatively correlated with disease severity markers (Gensini score, BNP, LDL-C, cTnI), and specific gene polymorphisms (rs4636297 and rs1140713) were associated with AMI risk and circulating mir-126 levels [Haiqiang Hu et al. DOI:10.1089/gtmb.2018.0282].
