Figure 4. Western blot analysis of lung tissue homogenates showing increase of Socs3, Atf3 and Gadd45a protein synthesis in response to 6₂S.

(A) Representative Western blots for Socs3, Atf3, Gadd45a and β-Tubulin, and (B) corresponding densitometric analysis. All samples were normalized to β-tubulin and expressed as fold induction. Data represent mean ±SEM for n = 5/group. Analysis of variance (Student–Newman–Keuls post hoc test), *P<0.05 vs. control.
