The mean migration rates of cancer cells transfected with pRNAT-shRNA-GPC5-1 were reduced compared with the controls in A549 (P<0.001) and H3255 (P=0.001), while the migration rate of SPC-A1 with GPC5 overexpression was higher than that of the control (P=0.001). The gene discussed is GPC5; the disease is cancer.
