A study in mice demonstrated that cocaine self-administration induces differential expression of 90 striatal circular RNAs, with 18 up-regulated and 72 down-regulated [Bu et al. DOI:10.1038/S41398-019-0527-1]. A study in humans demonstrated that circular transcripts of SLC22A6 are specifically expressed in urine and serve as a urine-specific biomarker for body fluid identification, with its inclusion in detection assays not impairing specificity [Liu et al. DOI:10.1007/s00414-019-02027-y]. circSLC22A6 harbors a low expression level of circular transcripts but maintains a high level of expression with a tissue-specific pattern, validating its forensic application for distinguishing urine from other forensically relevant body fluids [Song et al. DOI:10.1007/s00414-023-03091-1].
