Figure 1. A, Expression of hypoxia inducible factor-1α (HIF-1α) mRNA determined by RT-qPCR. Data are reported as fold of control. B, Expression of HIF-1α protein level determined by western blotting. Data (lower panel) are reported as the average absorbance of HIF-1α protein of three independent experiments. *P<0.05 (ANOVA).
