Wound healing showed that miR-106b-5p overexpression promoted RCC cells migration, but extra PDCD4 overexpression supplement in RCC cells transfected with miR-106b-5p mimic would inhibited cell migration compared with RCC cells transfected with miR-106b-5p mimic, as shown in Figure 3(g). The gene discussed is PDCD4; the disease is renal cell carcinoma.
