The discovery of genetic variants associated with OUD is constrained by limited genomic data, making it crucial to identify these variants and their genetic factors. The identification of variants from RNA-seq (RNA-sequencing) data can become the representative of the SNP analysis that is generally preferred from the whole genome or exome sequencing data. This study aimed to identify variants from gene expression data downloaded from NCBI GEO with accession PRJNA492904 in postmortem ventral midbrain specimens of chronic opioid users.

Circular RNAs (circRNAs) contribute significantly to tumor progression, functioning as microRNA (miRNA) sponges and interacting with RNA-binding proteins (RBPs). While circRNA-miRNA-mRNA regulatory networks have been studied in cervical cancer, the lack of intermediate neoplastic samples has limited the understanding of circRNA-driven progression from HPV-positive (HPV <sup>+</sup>) or HPV-negative (HPV <sup>-</sup>) normal cervical epithelium (NCE) to cervical squamous cell carcinoma (CSCC). This study addressed that gap by identifying differentially expressed (DE) circRNAs across four comparisons: high-grade squamous intraepithelial lesions (HSIL) vs. HPV <sup>+</sup> NCE, HSIL vs. HPV <sup>- </sup>NCE, CSCC vs. HPV <sup>+ </sup>NCE, and CSCC vs. HPV <sup>-</sup> NCE, using the limma R package.
