Applying a set of bioinformatic tools, we constructed a network of circRNA–miRNA and genes interactions, identifying two of the differentially expressed circRNAs, hsa_circRNA_404337 and hsa_circRNA_051799, that interact with genes known to associate with molecular pathways involved in the pathogenesis of sporadic PAs, such as CDKN1B and CDK1 [4,19], respectively. Here, CDKN1B is linked to gonorrhea.
