Effects of baicalin on key proteins in the Nrf2 signaling pathway in H₂O₂-stimulated IPEC-J2 cells. Immunofluorescence detection of nuclear Nrf2 protein import in IPEC-J2 cells (A). Western blotting was used to determine the expression of HO-1, Nrf2, β-actin, and lamin B (B). Cytoplasmic and nuclear Nrf2 protein expression (C). Data are presented as the mean ± SEM (n = 3 per treatment, *p < 0.05 compared with the model group). CON, control; L-Bai, low-concentration baicalin; M-Bai, middle-concentration baicalin; H-Bai, high-concentration baicalin.
