In the research of bladder carcinoma, Zhong discovered that circTCF25 was highly expressed in bladder carcinoma, further mechanism studies demonstrated that circTCF25 could promote bladder carcinoma cell line proliferation and migration through suppressing miR-103a-3p and miR-107 expression, and increasing CDK6 expression [41]. Here, CDK6 is linked to urinary bladder carcinoma.
