Von Hippel-Lindau (VHL) Protein Antagonist VH298 Improves Wound Healing in Streptozotocin-Induced Hyperglycaemic Rats by Activating Hypoxia-Inducible Factor- (HIF-) 1 Signalling

Figure 6

Immunohistochemical analysis reflecting the activation of the HIF signalling pathway following VH298 treatment. (a1–c1) VH298 treatment significantly enlarged HIF-1α-, hydroxy-HIF-1α-, and VEGF-A-positive areas (brown) compared to PBS treatment. (a2–c2) Values expressed as the positive percentage of each group. Graphs represent (VH298-treated vs. PBS-treated) (). and . n.s.: not significant.
