Fold induction relative to lane 1 was plotted as mean ± S.D. ∗P < 0.05 compared with the control. HASMCs (E) & HUVECs (F) were exposed to 1 µM PGE1 for the indicated times under 20% O2 & were harvested for immunoblot assay for HIF-1 alpha protein. Experiments were repeated twice. Representative immunoblots are shown. (H) HASMCs & HUVECs were exposed to 10 µM PGE1 for 4 h under 20% O2 & were harvested for immunoblot assay for HIF-2 alpha protein. Experiments were repeated twice. Representative immunoblots are shown. I. HASMCs were exposed to 1 µM PGE1, lipo-PGE1 & PGE1-alfadex under 20% O2 conditions for 4 h. After treatment, cells were harvested & whole-cell lysates were subjected to immunoblot assay for HIF-1 alpha .
