Western blotting data indicated PXR (A), CAR (B), and PPARα (C) in the APT Group compared to the Control Group using the iBright imaging system. Molecular weights are 50 kDa (PXR), 40 kDa (CAR), and 52 kDa (PPARα), respectively. The near-term (144d GA) liver tissue was used as a positive control for PXR, CAR and PPARα antibodies. For normalization, each NR intensity was quantified relative to the total protein intensity using No-stain Protein Labeling Reagent.APT, artificial placenta therapy; CTR, Control; PXR, pregnane X receptor; CAR, constitutive androstane receptor; PPAR, peroxisome proliferator-activated receptor; MRP, multidrug resistance-associated protein
