A study in mice demonstrated that the miR-671-5p was identified as a biomarker for predicting the impact of radiation exposure [Jia et al. DOI:10.1016/j.toxlet.2024.07.911]. In human monozygotic twins, the miR-671-5p was identified as a differentially expressed microRNA shared across two pairs, indicating its potential role in distinguishing genetically identical individuals [Xiao et al. DOI:10.1016/j.fsigen.2019.05.003].
