CYTOR and urinary bladder cancer: A study by Miao et al also showed that LINC00612 acted as a ceRNA for miR‐590 to promote bladder cancer cell proliferation and invasion.21 CYTOR could competitively inhibit several miRNAs in many cancers, such as miR‐139‐5p,22 miR‐153,7 and miR‐497,23 indicating that interacting with miRNAs might be the potential mechanism through which CYTOR drives NPC metastasis.
