Figure 9: Western blot analysis showing the effect of curcumin on HIF-1α expression in the lungs of rats exposed to hypoxia (a) HIF-1α and (b) VEGF. Rats treated with curcumin and exposed to hypoxia showed stabilized HIF-1 α expression and reduced levels of VEGF expression compared to control. The densitometry analyses were represented below their respective analyses. Values are mean ± SD (n=6). a P < 0.001 compared with Normoxia (0 h) group. b P < 0.05 compared with hypoxia (6 h) group. N=Normoxia, H=Hypoxia, Cur=curcumin.
