PPARA and fetal growth restriction: Icariin (ICA) functions as an agonist of PPARα, effectively modulating the PPAR signaling pathway to exert a lipid‐lowering effect.[44] Male IUGR piglets were orally administered ICA (20 mg kg−1 BW) daily from 7d to 28d, and liver and serum samples were collected after euthanasia (Figure8a).
