PRKAA1 and fetal growth restriction: EGF supplementation significantly increased Na+/K+-ATPase activity (p < 0.05), AKP activity (p < 0.01), SGLT1 (p < 0.01), GLUT2 (p < 0.01), and AMPK-α1 (p < 0.01) mRNA expression in the jejunum of IUGR piglets compared with IUGR piglets without EGF supplementation.
