Women who developed eclampsia/pre-eclampsia with severe renal and neurological complications or had neonatal deaths/still births were more likely to have the high-producer allele T in codon 10 of the transforming growth factor-beta 1 gene than healthy controls.
While the TLR-2 +2258 (G>A) and MMP-9 -1562 (C>T) SNPs failed to present any significant association with pre-eclampsia, there was a marked trend for an association between the IL-4 -590 (C>T) SNP and pre-eclampsia (chi(2)= 5.87, P = 0.055), with a prevalence of TT homozygous women in this group (OR 4.455, 95% CI 1.286-15.350).

Western blotting was used to study transcription factor activated protein 1 (AP-1) (JunB and FosB subunits) and nuclear factor (NF)-κB p65 in the HTR-8/SVneo cells and placentas from patients with pre-eclampsia.

We used RT-PCR, immuno-histochemistry and Western blotting to characterize DUSP9 gene expression and protein levels across human gestation and in pregnancies complicated by severe IUGR and/or severe pre-eclampsia.
We suppose the low expression of CD24 may cause the enhanced immune reaction and could play a role in the abnormal development of placenta in pre-eclampsia.
We speculate that if oxygen tension fails to increase, or trophoblasts do not detect this increase, HIF-1alpha and TGFbeta3 expression remain high, resulting in shallow trophoblast invasion and predisposing the pregnancy to pre-eclampsia.
We review the literature on the possible role of hypoxia in the etiology of IH, in particular, (1) the role of hypoxia inducible factor-1α (HIF-1α) and its downstream targets including GLUT-1 and VEGF; (2) the pathophysiological link between IH and retinopathy of prematurity; (3) hypoxic events in the early life including placental insufficiency, pre-eclampsia and low birthweight that have the potential to promote hypoxic stress; and (4) the evidence supporting the development of IH independent of HIF-1α.

We genotyped a total of 171 cases with preeclampsia or eclampsia and 185 normotensive control subjects for the methylenetetrahydrofolate reductase (MTHFR) 677 C --> T genotype.
We evaluated the association of the mutated genotypes Met235Thr-AGT, Thr174Met-AGT, I/D-ACE, A2350G-ACE, A1166C-AT2R1, C3123A-AT2R2, (83)A/G-REN with the risk and outcome of pre-eclampsia; we also investigated whether genes in newborns increase maternal risk of pre-eclampsia.
We determined whether polymorphisms in the promoter region of the tumour necrosis factor alpha (TNF-alpha) gene contributes to differences in susceptibility to develop pre-eclampsia.
We conclude that the thioredoxin and glutaredoxin reducing systems are affected in placenta from pregnancies with pre-eclampsia and/or growth restriction of fetuses, and that the decrease correlates to the severity of the condition.
