Fig. 7. Hypoxia enhanced expressions of Cp, iNOS and COX-2 and decreased nitrite production in A549 cells.

Fig. 7

A549 cells were treated with or without LPS/cytokine mixture for 24 hrs under normoxic (21% O2) or hypoxic (1% O2) conditions with serum deprived DMEM medium. The expressions of Cp, iNOS and COX-2 were detected by Western blotting (A). The nitrite levels in conditioned media were measured by NOA (B). *ρ < 0.05 and **ρ < 0.01 compared to respective controls.
