As shown in Figures 3D, 3E, 3F and 3G, compared with the negative control, cell migration ability was obviously suppressed in bladder cancer cells transfected with tetracycline-inducible CCAT2 shRNA group (P<0.05 in T24 and P<0.01 in 5637). The gene discussed is CCAT2; the disease is urinary bladder cancer.
