A study in rats demonstrated that the circLMTK2 was identified as a putative heroin-associated biomarker in a microarray analysis of orbitofrontal cortex tissue following heroin self-administration, though its amplification was undetectable in subsequent validation qPCR [Floris et al. DOI:10.3390/ijms23031453]. CircRNAs, as a class, exhibit stability in postmortem tissues and body fluids, supporting their potential for forensic applications such as postmortem interval estimation and body fluid identification [Tian et al. DOI:10.3390/molecules26041155].
