Li et al. [76] reported that KCNQ1OT1 modulated the malignant phenotypes of bladder cancer cells by specifically binding to miR-218–5p and increasing the expression level of heparan sulfate-glucosamine 3-sulfotransferase 3B1 (HS3ST3B1). This evidence concerns the gene HS3ST3B1 and urinary bladder carcinoma.
