Protective Role of Psoralea corylifolia L. Seed Extract against Hepatic Mitochondrial Dysfunction Induced by Oxidative Stress or Aging

Figure 3

Antioxidant mechanism of the PCS extract on hepatocytes. HepG2 cells were treated with (200 μg/mL) of the PCS extract for 24 h, and 1 mM H₂O₂ was added for the last 3 h. (a)–(d) The mRNA levels of antioxidation-related genes were analyzed by qRT-PCR. (e) Protein levels of antioxidation-related enzymes were analyzed using western blotting. (f) SOD activity. (g) GPX activity. *𝑃<0.05 versus (−)/H₂O₂. CON, treatment with nothing. Resveratrol (Res, 50 μM) was used as a positive control.
