background: spontaneous abortion is considered as the most complex problem during pregnancy. thrombophilia is resumed as a cause of recurrent pregnancy loss (rpl). glycoprotein iiia (gpiiia) gene is involved in thrombosis and abortion. angiotensin converting enzyme (ace) converts angiotensin i to angiotensin ii and is involved in thrombosis. the most common polymorphism in this gene is the inse...

The total CYP3A5 mRNA level is significantly greater in carriers of the CYP3A5*1 allele than in CYP3A5*3 homozygotes. Most of the CYP3A5*3 mRNA includes an intronic sequence (exon 3B) containing premature termination codons (PTCs) between exons 3 and 4. Two models were used to investigate the degradation of CYP3A5 mRNA: a CYP3A5 minigene consisting of CYP3A5 exons and introns 3 to 6 transfected...

background: regulatory cd4+t (treg) cells are effective in maintaining immune tolerance. objective: to investigate single nucleotide polymorphisms (snps) of transforming growth factor β-1 (tgf-β1) and forkhead box protein 3 (foxp3) genes in iranian patients with allergic rhinitis (ar). methods: variations at codons 10 and 25 of tgf-β1 and foxp3 at positions -3279 a>c and -924 a>g were evaluated...

metabolic syndrome (mets) is characterized by a cluster of cardiovascular risk factors that include: abdominal obesity, dyslipidaemia, hypertension, insulin resistance and impaired glucose tolerance. recent genome wide association studies have identified several susceptibility regions involved in lipid metabolism that are also associated with mets. we have explored the association of 9 genetic ...

Background: Metformin is an insulin sensitizing drug, which is co-administered with Clominophene citrate or gonadotropins in most cases of polycystic ovary syndrome (PCOS), to improve ovulation. STK11 gene is necessary for action of metformin. Therefore the study of STK11 polymorphisms is important as pharmacogenetics aspects of metformin. The aim of our study was to investigate polymorphism of...

Introduction: Considering the effectiveness of polymorphisms in the occurrence of respiratory diseases, it seems that these genetic variations in viral and microbial receptors can be effective in the occurrence and progression of the disease. The present study aimed to  assess the relationship between the C-159T polymorphism in the CD14 gene promoter and the severity of the disease in  Covid-19...

Background: Pre-eclampsia (PE) is one of the most important and life-threatening pregnancy disorders that affect at least 3-5% of all pregnancies. Imbalance in helper T cell functions may play a role in predisposing to PE or severity of the disease. Elevated frequencies of Th17 cells in the peripheral blood of PE patients have been reported. Several single nucleotide polymorphisms (SNP) within ...

The treatment of cancer depends on the activity cytochrome P450 enzyme family, which is essentially carried out by CYP3A4 and CYP3A5 enzymes. aim our study was to investigate whether polymorphism could contribute protein their influence response cells treatment. variability cDNA profiles between cell lines parental HT-29 resistant HT-29-OxR adenocarcinoma detected using denaturing gradient gel ...
