Introduction Genetic background has known to be associated with the outcome of human T cell lymphotropic virus (HTLV) type I infection. In The present study we investigate the association between GM-CSF gene polymorphisms with the outcome of HTLV-I infection. Materials and Methods We analyzed 3 single-nucleotide polymorphisms in the promter region of granulocyte macrophage colony stimulating...

objective(s): asthma results from the interaction between genetic and environmental factors. adam33 gene on chromosome 20p13 is associated with asthma and airway hyperresponsiveness. materials and methods: this is a case-control study, where four snps s1 (rs3918396), t1 (rs2280091), t2 (rs2280090), v4 (rs2787094) of adam33 gene have been assessed in patients with allergic asthma and normal cont...

Polymorphisms in the genes of drug-metabolizing enzymes have potential to contribute inter-individual differences drug pharmacokinetics and toxicity. A custom next-generation sequencing (NGS) panel was used 71 kidney transplanted patients study polymorphisms 11 relevant metabolism immunosuppressive drugs. Cyclosporine tacrolimus concentrations were determined by a validated liquid chromatograph...

Background: Drug-metabolizing enzymes play a role in chemical carcinogenesis through enzymatic activation of procarcinogens to biologically reactive metabolites. The role of gene polymorphisms of several cytochrome P450 enzymes in digestive cancer risk has been extensively investigated. However, the drug-metabolizing enzymes with the broader substrate specificity, CYP3A4 and CYP3A5, have not be...

background: recurrent pregnancy loss is (rpl) a heterogeneous condition. while the role of acquired thrombophilia has been accepted as an etiology for rpl, the contribution of specific inherited thrombophilic gene polymorphisms to the disorder has been remained controversial. methods: one hundred women with a history of two or more consecutive abortions and 100 women with at least two live birt...

INTRODUCTION Levonorgestrel a synthetic progestagen used for endometriosis, dysmenorrhea and emergency contraception, is quickly and completely absorbed in the digestive tract. levonorgestrel is predominantly metabolised through hepatic routes that utilise the CYP3A system (CYP3A4 and CYP3A5). OBJECTIVE This study aimed to evaluate the association between variant alleles of CYP3A4*1B and CYP3...

BACKGROUND Tacrolimus (Tac) is a potent immunosuppressant with considerable toxicity. Tac pharmacokinetics varies between individuals and thus complicates its use in preventing rejection after kidney transplantation. This variability might be caused by genetic polymorphisms in metabolizing enzymes. METHODS We used TaqMan analyses to evaluate the impact of a newly discovered CYP3A4 (cytochrome...

Clinical outcomes of vincristine therapy, both neurotoxicity and efficacy, are unpredictable, and the reported pharmacokinetics of vincristine have considerable interindividual variability. In vitro and in vivo data support a dominant role for CYP3A enzymes in the elimination of vincristine. Consequently, genetic polymorphisms in cytochrome P450 (P450) expression may contribute to the interindi...

tumor necrosis factor alpha-inducible protein 3 (tnfaip3) gene polymorphisms have been reported to be associated with the susceptibility to several immune-related diseases. here we investigated the effect of tnfaip3 gene polymorphisms on the risk of allergic rhinitis (ar) in a chinese han population. the case-control study included 540 ar patients and 524 healthy controls. genotyping for tnfaip...

To study mechanisms behind the interindividual variability in CYP3A expression and the relative contribution of the different CYP3A enzymes to the overall CYP3A activity, we have analyzed CYP3A4, CYP3A5, CYP3A43, and PXR mRNA and CYP3A4 and CYP3A5 protein expression, catalytic activity, and polymorphism in the CYP3A5 gene in a panel of 46 Caucasian human livers. Protein quantification was perfo...
