Expression of citrate synthase (Cs) and hydroxyacyl-CoA dehydrogenase (Hadh) was upregulated in IUGR rats at 5 dpp, compared to controls (P < 0.02), whereas at 40 dpp, lactate dehydrogenase-a, -b and -c (Ldh-a, Ldh-b and Ldh-c) were downregulated (P < 0.002, P < 0.02, P < 0.02, respectively) and solute carrier family 2 member 1 (Slc2a1) was upregulated (P < 0.01) in IUGR rats compared to controls. Here, LDHA is linked to fetal growth restriction.
