Association between HLA-E gene polymorphism and unexplained recurrent spontaneous abortion (RSA) in Iranian women
Journal Title: International Journal of Reproductive BioMedicine - Year 2016, Vol 14, Issue 7
Abstract
Background: Human leukocyte antigen-E (HLA-E)is a non-classical major histocompatibility complex (MHC) class I antigens which expressed on extra villous cytotrophoblast, which interacts with NKG2A, is an inhibitory receptor on natural killer (NK) cells and leading to down regulation of immune response in the maternal-fetal interface and provides maternal immune tolerance of the fetus. Objective: This study was designated to investigate the gene frequencies of E0101 and E0103 in HLA-E gene in Iranian women with recurrent spontaneous abortion (RSA). Materials and Methods: Amplification Refractory Mutation System (ARMS-PCR) technique was carried out to detect polymorphism in exon 3 of the HLA-E gene in women with RSA and controls (n=200). Differences between groups were analyzed by SPSS19 software using 2 test. Results: There was no significant difference in the allele frequencies of the HLA-E polymorphism between RSA and fertile controls but HLA-E 0101/0103 heterozygous genotype was found to be significantly higher in RSA group (p=0.006, OR=1.73), so this genotype might confer susceptibility to RSA. Conclusion: Our results suggest that HLA-E 0101/0103 heterozygous genotype leads to increase of RSA risk. It seems that by genotyping of HLA-E polymorphism, we can predict the risk of RSA in infertile women.

Effect of linoleic acid supplementation on in vitro maturation, embryo development and apoptotic related gene expression in ovine
Background: Linoleic acid (LA) is a polyunsaturated fatty acid present in high concentrations in follicular fluid, when added to maturation culture media, it affects oocyte competence. Objective: In the present study, we...
Final follicular maturation by administration of GnRH agonist plus HCG versus HCG in normal responders in ART cycles: An RCT
Background: Gonadotropin-releasing hormone agonists (GnRH-a) was increasingly used for triggering oocyte maturationfor the prevention of ovarian hyperstimulation syndrome. Studies suggest that GnRH-a might be used as a b...
