Figure 4.

Western blot analysis for the denoted proteins and their phosphorylation status after cultivation of the cell lines under standard cell culture conditions for 14 days (S), under hypoxia (1% O₂) for 14 days (H), and after cultivation under hypoxia for 14 days followed by reoxygenation (10% O₂) for 4 h (R). Three biological replicates were analyzed for each cell line.
