LSINCT5 activates Wnt/β‐catenin signalling by interacting with NCYM to promote bladder cancer progression.12 While the functions and mechanisms of lncRNAs are still remain largely unknown, it of great significance to explore novel lncRNAs and identify their functions, which might provide potential therapeutic targets for clinical treatments of bladder cancer patients. Here, MYCNOS is linked to urinary bladder cancer.
