The effect of MG infection and/or baicalin on transcription factor Nrf2 and its downstream genes (HO-1, NQO1, GSTA2). Panel (A) shows the protein expression levels of Nrf2, NQO1 and HO-1 and panel (B) shows the mRNA expression level of Nrf2, NQO1, HO-1, and GSTA2. Whereas, experimental groups consist of (A) Control group (B) Model group (C) Baicalin alone treated group (450 mg/kg) and (D) Model group treated with baicalin (450 mg/kg). Statistical significance were represented as ∗P < 0.05 vs. control group, ∗∗P < 0.05 vs. model group. All the bar graphs shows mean results ± SD (n = 3).
