Actin-related protein 3 (Spot F26), actinin, alpha 4 isoform 12 (ACTN4, Spot F52), cytokeratin 19 (CK19, Spot L12), cytokeratin 8 (CK8, Spot F93), beta actin (ACTB, Spot F71), and microtubule-actin (Macf1, Spot L90), were down-regulated in the IUGR group, while T-complex protein 1 subunit (TCP1, Spot F9), tubulin, alpha, ubiquitous isoform 19 (TBLA, Spot F230), beta actin (ACTB, Spot L221), and gamma-actin (ACTG, Spot L220) were up-regulated in the IUGR group, as compared with NBW fetuses. The gene discussed is KRT19; the disease is fetal growth restriction.
