Figure 9. Skp2 downregulation enhances miR-506-induced upregulation of FOXO1 and p57. (A) Immunoblotting was done to evaluate the protein level of Skp2 and its targets in osteosarcoma cells after miR-506 mimic transfection and Skp2 downregulation. (B) Quantitative results of (A). *p < 0.05 vs control, #p < 0.05 vs miR-506 mimics or Skp2 siRNA transfection.
