(A) Immunoblot of HIF-1α and HIF-1β (loading control) in PASMCnorm. Cells were treated for 4 hours in either hypoxic medium (Hyp) or normoxic medium (Norm) with or without DMOG at concentrations of 10 μM, 100 μM and 1 mM. Hypoxia and DMOG at the two higher concentrations stabilized HIF-1α and the DMOG dose of 100 μM was chosen as being closest to the physiological level of hypoxia. Both hypoxia and DMOG (100 μM) inhibited [3H]-Thymidine incorporation in PASMCnorm (B) and increased [3H]-Thymidine incorporation in PASMChyp (C). n=3; *P<0.05 vs. normoxia.
