In this study, we find that expression of several key regulators for cell proliferation, including EIF5A2, EIF6, AspRs, and ZFP 420 [40, 41], were decreased in the IUGR placenta, and eEF1A-1, HNRNPK, and LAMN were decreased in the IUGR endometrium. The gene discussed is HNRNPK; the disease is fetal growth restriction.
