OIP5 and hepatocellular carcinoma: Based on these findings, the ceRNA axes involving OIP5-AS1/hsa-miR-204-5p/BIRC5, DCP1A/hsa-miR-204-5p/BIRC5, and PPP1R9B/hsa-miR-204-5p/BIRC5 appear to play a crucial role in the progression of HCC, suggesting potential avenues for targeted therapeutic interventions in this type of cancer.
