A study in humans established a multi-class support vector machine classification model for forensic body fluid identification using TaqMan RT-qPCR, which achieved 98% accuracy on an independent test set and demonstrated utility for aged casework samples [Li et al. DOI:10.1016/j.fsigen.2024.103180]. A study in mice demonstrated that the miR-450a-5p was differentially expressed in blood 6 hours after γ-irradiation [Jia et al. DOI:10.3389/fcell.2022.861451]. In Sprague-Dawley rats, the miR-450a-5p was upregulated 1.99-fold in the corpus cavernosum of obese rats with erectile dysfunction [Bai et al. DOI:10.1016/j.esxm.2017.06.006].
