A study in UChB rats demonstrated that chronic ethanol consumption increased cerebellar expression of several miRNAs, while caffeine co-administration reduced these levels, with plasma levels not reflecting cerebellar changes [Rossetto et al. DOI:10.1016/J.Lfs.2019.05.016]. In human peripheral blood mononuclear cells, the miR-3180-3p was identified as downregulated following a 1 Gy fractionated radiation exposure [Lee et al. DOI:10.1155/2014/456323].
