To confirm whether USP18 could be a target gene of miR‐328‐3p, we transfected a luciferase reporter vector harbouring the USP18 3′‐UTR into bladder cancer cell lines (Figure S24A, Supporting Information), and relative luciferase activity was then detected after miR‐328‐3p mimic transfection. The gene discussed is USP18; the disease is urinary bladder cancer.
