Suppression and over-expression of HIF-1α: graphical format. Densitometric analysis was performed on the western blot shown in figure 3 and displayed here in graphical format. $, P < 0.05 compared to control and HIF-1α siRNA; #, P < 0.05 compared to normoxic and hypoxic HIF-1α siRNA; *, P < 0.05 compared to hypoxic mock transfected and scrambled HIF-1α control siRNA transfection. siRNA: HIF-1α plasmid transfected, Mock: mock transfected, HIF: HIF-1α expression plasmid transfected.
