Analytical approach overview. RNA-sequencing was carried out in brain tissue collected postmortem from individuals with opioid use disorder (OUD) and controls. smallRNA-seq was carried out in both brain and blood tissue from a subset of the same individuals. Dysregulated miRNA–RNA networks were inferred, and miRNA target genes were further investigated using pathway enrichment, repurposable drug identification, and correlation-based network analysis.
