AGTR2 blocking peptide

Purpose: Preeclampsia, specific to human pregnancies, is a serious disorder, which occurs approximately in 6-10% of all pregnancies. It is a complex disorder, in which immune and genetic factors also take part. The aim of the current study was toinvestigate whether there is an association between AGTR2 A1675G and IL4 -590 (C>T) polymorphisms and preeclampsia. Material and Methods: Genomic DNA was extracted from the peripheral venous blood of 131 preeclamptic and 86 normotensive pregnant women. The AGTR2 and IL-4 polymorphisms were genotyped by using a polymerase chain reaction assay. Results: As for AGTR2 gene 1675 polymorphism, there was not any significant difference in terms of genotype frequencies but there was a significant difference in terms of allele frequencies. As for IL-4 gene -590 polymorphism, there was not any significant difference in terms of genotype and allele frequencies. Conclusions: AGTR2, GG genotype and IL-4, TT genotype were found significantly higher in preeclamptic women than normotensive pregnant women. These genotypes might be a susceptibility risk factor for preeclampsia but these findings need to be tested in a larger sample size.

The article presents the results of the study of the frequencies of occurrence of single nucleotide polymorphisms of the genes ADD1 alpha (1378 G> T), AGT (704 T> C and 521 C> T), AGTR1 (1166 A> C) and AGTR2 (1675 G> A) groups of residents of the Arctic zone of the RS (Ya), suffering from essential arterial hypertension. Subjects of the research were represented by the most widespread ethnic groups in the territory, including the Slavs, Yakuts, Evens and Evenks. To reveal the above mentioned polymorphisms, a real-time PCR method was used with detection of the melting temperature of duplexes. In the course of the study statistically significant differences between the study groups were identified by the points ADD1 alpha 1378 G> T; AGT 521 C> T and AGTR1 1166 A> C.
