Paeoniflorin Attenuated Oxidative Stress in Rat COPD Model Induced by Cigarette Smoke

Figure 5

Estimate of protein expressions throughout Western blot. GAPDH was used as the loading control. The optical density for target protein is shown as a proportion of GAPDH optical density. Here we detected the total amount of protein expressions of ATF-4 (a), Nrf2 (b), HO-1 (c), SOD (d), and γ-GCS (e) in the lung tissue. , , compared with the Normal Control group. , , compared with the COPD group. , , compared with Budesonide group.
