There are few published data on the association between transmembrane serine protease 6 (TMPRSS6) gene polymorphism and preeclampsia. Objective: To assess the association between TMPRSS6 gene polymorphism rs855791SNP in women with preeclampsia compared with healthy pregnant women. Method: A case-control study (60 women in each arm) was conducted at Saad Abuaela Maternity Hospital in Khartoum, Sudan. Sociodemographic and clinical data were gathered through a questionnaire. The participant was genotype for TMPRSS6 gene rs855791SNP using Polymerase Chain Reaction and Restriction Fragment Length Polymorphism (PCR-RFLP). The results were confirmed by DNA sequencing. Result: There was no significant difference in the median of age, parity, and body mass index. The distribution of the genotypes and alleles of TMPRSS6 rs855791 was consistent with the HWE. The overall TMPRSS6 rs855791 polymorphism was not significantly associated with preeclampsia. However, the proportion of heterozygotes (TC) was considerably higher in the women with preeclampsia (46.7%) than in the control group (23.3%) (p = 0.001;OR = 2.71;95% CI = 1.21 - 6.07). The proportion of homozygotes (TT) and T alleles was not significantly different between women with preeclampsia and the control group. Conclusion: The overall TMPRSS6 rs855791 polymorphism was not significantly associated with preeclampsia and healthy control.展开更多

Methods: The placentae of preeclamptic and normotensive subjects with pregnancy were used as models, and the eDNA Library was constructed and 20 differentially expressed fragments were cloned after a new version of PCR-based subtractive hybridization. The false positive clones were identified by reverse dot blot analysis. With one of the obtained gene taken as the probe, the placentas of 10 normal pregnant women and 10 preeclamptic patients were studied by using dot hybridization methods. Results: Six false positive clones were identified by reverse dot blot, and the rest 14 clones were identified as preeclampsia-related genes. These clones were sequenced, and analyzed with BLAST analysis system. Eleven of 14 clones were genes already known, among which one belongs to necdin family; the rest 3 were identified as novel genes. These 3 genes were acknowledged by GenBank, with the accession numbers AF2322 16, AF2322 17, AF233648. The results of dot hybridization using necdin gene as probe were as follows: (1) There was this mRNA in the placental tissues of normal pregnancy as well as in that of preeclampsia. (2) The intensity of transcription of this mRNA in the placental tissues of preeclampsia increased significantly compared with that of the normal pregnancy (P＜0.05). Conclusions: This study for the first time reported this group of genes, especially necdin-expressing gene, which are related to the etiopathology of preeclampsia. In addition, the overtranscription of necdin gene has been found in preeclampsia. it is helpful in further studies of the etiology of preeclampsia.展开更多

Peripheral blood was collected to determine PECAM-1 gene C373G polymorphism as well as the contents of endothelial injury molecules sEng, PAR-1, sFlt-1 and ET-1;placenta tissue was collected to determine the contents of pathological damage molecules Gadd45 , TIMP2, Fas, Apaf-1 and caspase-3.Results:PECAM-1 gene C373G locus GC and GG genotype constituent ratio and allele G constituent ratio in peripheral blood of PE group were significantly higher than those of control group while CC genotype constituent ratio and allele C constituent ratio were significantly lower than those of control group. sFlt-1, sEng, PAR-1 and ET-1 contents in serum as well as Gadd45 , TIMP2, Fas, Apaf-1 and caspase-3 contents in placenta of PE group were significantly higher than those of control group;sFlt-1, sEng, PAR-1 and ET-1 contents in serum as well as Gadd45 , TIMP2, Fas, Apaf-1 and caspase-3 contents in placenta of PE patients with PECAM-1 gene C373G locus GC and GG genotypes were higher than those of PE patients with CC genotype.Conclusion: Increased allele G in PECAM-1 gene C373G loci is closely correlated with endothelial injury and placental pathological damage in patients with preeclampsia.展开更多
