Zhong et al. revealed that overexpression of circTCF25 downregulates miR-103a-3p and miR-107 and could regulate circTCF25-miR- 103a-3p/miR-107-CDK6 pathway in urinary bladder cancer, hence, promote proliferation and migration both in vivo and vitro [38]. This evidence concerns the gene CDK6 and urinary bladder cancer.
