SKIP Downregulation Increases TGF-β1-Induced Matrix Metalloproteinase-9 Production in Transformed Keratinocytes

Figure 3

SKIP depletion enhances TGF-β1-induced MMP-9 promoter transactivation. Transactivation of MMP-9 promoter in PDV/M and AS-S cells transfected with empty vector (EV) or plasmid containing HA-SKIP. MMP-9 promoter activity was assayed in cells stimulated and not with TGF-β1 for 48 h by using luciferase inducible activity. β-Gal was used as internal control of transfection. Insert, western blot showing the correct expression of ectopic SKIP. Alpha Tubulin (α-Tub) was used a loading control protein.
