SLC7A5 and fetal growth restriction: Postnatal nutrient restriction decreased mRNA abundance of LACS, FATP1, cationic amino acid transporter 1 (CAT1; p < 0.05), glucose transporter 4 (GLUT4; p < 0.05), and L-type amino acid transporter 1 (LAT1; p < 0.05) in the PM muscle of IUGR piglets than the NBW piglets (Figure 2 and Figure 3).
