Fig 6. IFN-α is upregulated under hypoxic conditions in Kl^−/− mice.

(A) Western blot analysis demonstrating IFN-α expression in WT and Kl^−/− mice. Protein levels were normalized to β-actin levels (n = 5 in each group). (B) Representative immunohistochemical staining images showing IFN-α expression in WT and Kl^−/− mice. Values are mean ± SD. *P < 0.05, **P < 0.01. Bar = 100 μm.
