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.
In all, 17 studies (including 1446 cases and 3829 controls) published in English between 1993 and October 2006 on the association of angiotensinogen gene M235T polymorphism with preeclampsia/eclampsia were selected.
The aim of the present study was to investigate the relationship between IL-lβ (C+3954T) and TNF-α (G-308A) gene polymorphisms with pre-eclampsia in north east of Iran (Khorasan province).This study included 54 diagnosed patients with pre-eclampsia and 50 normal pregnant women as control group.
Recent findings regarding aspects of HLA-G polymorphism, the possible significance of this polymorphism in respect to HLA-G function and certain complications of pregnancy (such as pre-eclampsia and recurrent spontaneous abortions (RSA)) are discussed together with possible importance to IVF.
Based on genotyping and full gene sequencing of HLA-G in a large number of cases and controls (n > 900), the present study, which to our knowledge is the largest and most comprehensive performed, investigated the association between the HLA-G 14-bp ins/del (rs66554220) and HLA-E polymorphisms in mother and newborn dyads from pregnancies complicated by severe preeclampsia/eclampsia and from uncomplicated pregnancies.
In order to evaluate whether lipid abnormalities may contribute to endothelial dysfunction in pre-eclampsia, the present study examined the in vitro effects of very-low-density lipoprotein (VLDL), low-density lipoprotein (LDL) and high-density lipoprotein (HDL), isolated from women with pre-eclampsia and matched controls, on the endothelial synthesis of 6-oxo-prostaglandin F(1alpha) (6-oxo-PGF(1alpha); a metabolite of prostacyclin) and endothelin 1, and on the expression of nitric oxide synthase 3 (NOS3) mRNA.
The frequency of HLA-G polymorphism in these samples was not significantly different from those of normal controls, indicating that maternal HLA-G polymorphism is not associated with the risk for pre-eclampsia in this Chinese Han population.
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.
This meta-analysis suggests that the MTHFR 677T allele might be associated with increased pre-eclampsia risk in Asian and white ethnicity and the subgroup of severe pre-eclampsia, while no association is observed between the MTHFRA1298C polymorphism and pre-eclampsia.
The aim of this study was to investigate whether the two common polymorphisms of the leptin (LEP) and adiponectin (APM1) genes are associated with the development of pre-eclampsia and its related traits (gestational hypertension, proteinuria and various measures of reduced fetal growth ) in the Czech pre-eclamptic population.
No statistically significant differences were observed in genotype or allele frequencies between the pre-eclampsia and normal control for the C677T polymorphism of MTHFR gene (<i>p</i> > .05).
The angiotensin-converting enzyme (ACE) intron 16 insertion/deletion (I/D) polymorphism is associated with ACE activity and has been discussed as a risk factor for pre-eclampsia.
Maternal/newborn genotype contribution of the renin-angiotensin system (Met235Thr, Thr174Met, I/D-ACE, A2350G-ACE, A1166C-AT2R1, C3123A- AT2R2, 83A/G-REN) to the risk of pre-eclampsia: a Romanian study.
Synergism of angiotensin-converting enzyme I/D and other polymorphisms of renin-angiotensin system components and nitric oxide synthase may be a risk factor for pre-eclampsia.
Here we studied whether two single nucleotide sequence variants, c.1744 C>T that changes residue 582 of HIF-1alpha from proline to serine (P582S) and c.1762 G>A that changes residue 588 of HIF-1alpha from alanine to threonine (A588T) in the exon 12 of the HIF1A gene, are associated with pre-eclampsia.
