Compared with NBW fetuses, expression of thioredoxin (TXN, Spot F10), peroxiredoxin 6 (PRDX6, Spot F218, F79), glucose-regulated protein (GRP94, Spot L144) and alpha-crystallin B chain (CRYAB, Spot L135) was higher, while expression of latexin (LXN, Spot F265), complement component 3 (C3, Spot F215), immunoglobulin gamma (IgG, Spot L323), and guanine nucleotide binding protein (GAQ, Spot F76) was lower in the IUGR endometrium, as compared with the NBW group. This evidence concerns the gene LXN and fetal growth restriction.
