Background and purpose: Brucellosis is a major bacterial zoonosis of global importance. Effective host defence against brucella depends on immunoglobulin G-mediated phagocytosis of the bacteria and it has been shown that the FC RIIA polymorphism (FCγ RIIA-R131 vs FCγ RIIA –H131) determines the capacity of immunoglobulin G-mediated phagocytosis via this receptor. The aim of this study was to e...
Osteoporosis is a metabolic bone disease affecting mostly elderly women. As metabolizing enzymes, the roles of few cytochromes have been studied in osteoporosis development. The aim of this study was to assess for the first time the association of CYP2E1 and CYP1A1 polymorphisms and osteoporosis in postmenopausal women. 112 postmenopausal women presenting osteoporosis and 93 age and sex matched...
PURPOSE The chemokine CXCL12 and its receptor CXCR4 have been found to be associated with cancer metastasis. A single nucleotide polymorphism of CXCL12 G801A has been described and is regarded as a target for cis-acting factor that has the ability to up-regulate CXCL12 expression. Currently, there are no reports investigating the role of CXCL12 G801A polymorphism in prostate cancer (PC). EXPE...
Background: Beta thalassemia is one of the autosomal recessive diseases that related to synthesis disorder of beta globin chain. It is caused by any of the more than 200 mutations in the β-globin gene. DNA sequencing and genotyping of numerous mutations at beta globin gene is timely and expensive. Therefore, the best method for screening is linkage using polymorph markers at beta globin region ...
In this study, we investigated the association between ACTN3 R577X polymorphism and non-acute ankle sprain by measuring the allele frequency and genotype distribution of ACTN3 in a Chinese Han population. We recruited 100 patients with non-acute ankle sprain and 100 healthy controls with no history of ankle injuries. Mass spectrometric analysis of single nucleotide polymorphism was used to anal...
In this study, we examined the frequency of polymorphisms in the interleukin (IL) genes IL-1β-511 and IL-6-174 in patients with epilepsy as well as a control group in Kars, Turkey. A total of 100 patients diagnosed with epilepsy and 100 nonepileptic subjects as a control group were examined. Peripheral blood samples were acquired from patients and control subjects for DNA extraction. The target...
Background: High level of perceived stress in nurses is due to a genetic predisposition and environmental stressors. The aim of NURSE (Nursing Unacquainted Related Stress Etiologies) study was to investigate the association of C677T MTHFR gene polymorphism and stress perception among nurses. Methods: In this comprehensive study, 216 female nurses were recruited. Perceived stress w...
Background and Objective: Prostate cancer is among the five common cancers in males. It is second cancer in terms of the age-standardized rate (ASR) (ASR=16.6) in Iran. The rs2735839 G/A, an intergenic polymorphism is located on chromosome 19q13.33 at 600 base pairs of the KLK3 gene untranslatable region. This gene which codes prostate-specific antigen (PSA) is used in the screening and diagnos...
frequency distributions from varying genotyping error rates and patterns” Christopher S. Carlson, Michael A. Eberle, Mark J. Reider, Leonid Kruglyak and Deborah A. Nickerson Department of Genome Sciences, University of Washington, 1705 NE Pacific, Seattle, Washington 98109. Division of Human Biology, Fred Hutchinson Cancer Research Center, 1100 Fairview Avenue N, Seattle, Washington 98109. Howa...
background and objective: host genetic factors such as cytokine gene polymorphisms as well as helicobacter pylori (h. pylori) infection have been found to be associated with gastric cancer risk . interleukin 1 is a pro-inflammatory cytokine involved in h. pylori-induced gastric inflammation. therefore, we analyzed the association between il-1β and il-1-rn polymorphisms and gastric cancer in per...
