In this ceRNA network, previous studies have confirmed that miR-3194-3p/AQP1 (43), miR-1246/AXIN2 (44), miR-326/E2F2 (45), miR-326/CDCA5 (46), and miR-17-3p/RGS2 (47), etc, interaction relations play important roles in the occurrence and development of various cancers. The gene discussed is CDCA5; the disease is cancer.
