Fig. 1From: Interaction between AhR and HIF-1 signaling pathways mediated by ARNT/HIF-1βEstablishment of cell spent oxygen microenvironment and selection of BaP concentration. A Expression level of HIF-1α mRNA after 24 h of treatment with different concentrations of CoCl2. B Effects of 300 μM CoCl2 on expression level of HIF-1α mRNA at different times in A549 cells. C Effects of different concentrations BaP on cell viability at different times in A549 cells.
