HIF1α downregulates PS expression in hypoxic HEPG2 cells. (A) Representative immunoblots showing relative PS and HIF1α protein levels in HEPG2 cells grown at different O2 concentrations. (B) Relative HIF1α mRNA levels in HEPG2 cells grown at different concentrations of O2. (C) Relative PS mRNA levels in HEPG2 cells grown at different concentrations of O2. ****P < .0001.
