Furthermore, we revealed that CYP4Z1 and the pseudogene CYP4Z2P form a ceRNA network via competiting with several miRNAs, such as miR-211, miR-125a-3p, miR-197, miR-1226, and miR-204, here called ceRNET_CC, and both we and others have shown that these shared miRNAs exert tumor suppressive effects [8–12]. This evidence concerns the gene CYP4Z1 and neoplasm.
