Background: Some genetic factors are involved in the etiology of Hashimoto thyroiditis and Graves’ disease as autoimmune thyroid diseases (AITDs). Effects of vitamin D receptor gene polymorphisms in AITDs development have already been investigated in some previous studies. However, no study has been done on the association between VDR FokI and ApaI polymorphisms and AITDs in an Iranian po...
Status of FAS and FAS Ligand Gene Polymorphisms in Patients wi th Breast Cancer in Northeastern IRAN
Background: The First apoptosis signal (FAS) and First apoptosis signal ligand (FASL) genes initiate the apoptosis pathway, playing a central role in the tumor growth and metastasis. Gene polymorphisms including -1377 G/A in the promoter region of FAS and -844 C/T in the promoter region of FASL have shown to change the transcription activities of these genes. Methods: In this study we evalua...
B. Pourgheysari[1][2], A. Hasheminia[3], H. Rouhi-Boroujeni3 Received: 20/02/2014 Sent for Revision: 22/01/2014 Received Revised Manuscript: 09/10/2012 Accepted: 28/07/2012 Background and Objective: Venous thromboembolism (VTE) is one of the main causes of mortality in different human communities. Factor V Leiden, MTHFR C677T polymorphism and PLA2 polymorphism of platele...
Background: Pro-inflammatory and anti-inflammatory cytokines and polymorphisms of their genes have been described to be involved in the pathogenesis of recurrent miscarriage (RM). Objective: To investigate the association between RM and five polymorphisms of cytokine genes, interleukin 10 (IL-10), (-592 A/C, -819 C/T, -1082 A/G), IL-6 (-174 C/G) and IL-17 (-197 G/A) in Iranian women. Method: Po...
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...
asthma as a chronic inflammatory airway disease is considered to be the most common chronic disease that is involving genetic and environmental factors. toll like receptors (tlrs) and other inflammatory mediators are important in modulation of inflammation. in this study, we evaluated the role of tlr2 arg753gln and tlr4 asp299gly polymorphisms in the asthma susceptibility, progress, control lev...
objective: plasmodium falciparum chloroquine resistance is a major problem in malaria endemic areas. single nucleotide polymorphisms in pfcrt and pfmdr1 genes are known to be associated with chloroquine resistance in some parts of the world. the major goal of the present study was to detect the five single nucleotide polymorphisms in pfmdr1 gene and one single nucleotide polymorphisms in pfcrt ...
A case of Kikuchi–Fujimoto Disease in a SLE patient; potential importance OR8U8 gene polymorphisms
Background: Coronary artery stenosis is one of the atherosclerotic complications which can lead to decreased oxygen supply in heart tissue and heart attack. rs1050450 Polymorphism is one of polymorphisms in GPx1 gene that may change its antioxidant activity. Furthermore, two polymorphisms of NADPH Oxidase, rs4673 and rs13306294, are suggested to have a role in the function of this enzyme. In th...
Abstract Background: Sporadic colorectal cancer is the fourth most common cancer in Iran. The DNA repair protein O6-methylguanine-DNA methyltransferase (MGMT) is involved in the cellular defense against alkylating agents. Genetic alterations in the MGMT gene may impair the protein’s ability to remove alkyl groups from the O6-position of guanine, thereby raising the mutation rate and increasi...
