Forensic Context

A study in humans demonstrated that the mir-1290 was selected as a candidate from microarray and literature for saliva identification but showed no specific amplification in pooled samples, likely due to methodological differences [Sauer et al. DOI:10.1016/j.fsigen.2016.01.018]; a separate review of human skin biology found the mir-1290 was downregulated in burn hypertrophic scar and its derived fibroblasts compared to normal fibroblasts, though it was upregulated in hypertrophic scar tissue versus normal tissue in another study [Siu et al. DOI:10.1111/wrr.13100]. A study in humans demonstrated that the mir-1290 is differentially expressed within monozygotic twin pairs, as it was shared across five pairs of twins in a microarray analysis of blood samples from Han Chinese individuals, suggesting its potential role in distinguishing genetically identical individuals for forensic identification [Xiao et al. DOI:10.1016/j.fsigen.2019.05.003]. Furthermore, a review notes that the mir-1290 in cerebral spinal fluid can accurately distinguish patients with Medulloblastoma from healthy individuals, highlighting its broader utility as a diagnostic biomarker [Liu et al. DOI:10.1016/j.ccr.2025.216644].
