OTUD4 and obstructive sleep apnea syndrome: Finally, we proposed twelve ceRNA regulatory pathways in OSA, including four ZNF117-mediated (ZNF117-hsa-miR-455-3p-XIST, ZNF117-hsa-miR-455-3p-KCNQ1OT1, ZNF117- hsa-miR-455-5p-OIP5-AS1, and ZNF117-hsa-miR-455-5p-KCNQ1OT1), four RRN3-mediated (RRN3-hsa-miR-3609-KCNQ1OT1, RRN3-hsa-miR-32-5p-XIST, RRN3-hsa-miR-32-5p-OIP5-AS1, and RRN3-hsa-miR-32-5p-KCNQ1OT1), and four OTUD4-mediated (OTUD4-hsa-miR-455-3p-XIST, OTUD4-hsa-miR-455-3p-KCNQ1OT1, OTUD4-hsa-miR-31-5p-XIST, and OTUD4-hsa-miR-31-5p-KCNQ1OT1) ceRNA networks, respectively (Figure 8E).
