ACE and PLA2G7genes expression in children with a history of food anaphylaxis

Abstract

Background. The aim of this study was to evaluate transcriptional activity of PLA2G7 (platelet-activating factor acetylhydrolase) and ACE (аngiotensin-сonverting enzyme) genes in patients with a history of anaphylaxis. Methods. 97 children were enrolled in the study: 27 children with a history of food anaphylaxis; 35 children with atopic dermatitis; 35 children without allergic diseases: 26 children were IgE-negative, 9 children were IgE-positive («Phadia 100»; «Phadia AB», Sweden). RNA was extracted from blood samples with Trizol RNA Prep kits («Isogen», Russia). cDNA production was performed with MMLV RT kit («Evrogen», Russia). Real-time PCR was held with CFX-96 device («Bio-Rad», USA) and qPCRmix-HS PCR mix («Evrogen», Russia). Oligonucleotide primers and probes were synthesized at «DNK-Sintez» (Russia). Results. In children with a history of food anaphylaxis decrease in PLA2G7 gene expression was detected comparing to control groups (p
