خلاصه: Methylation of DNA is one of the important regulatory mechanisms of gene transcription. B-cell chronic lymphocytic leukemia/ lymphoma 11B (BCL11B) plays a key role in the development, proliferation, differentiation, and survival of T cells. The aim of this study was to evaluate promoter methylation of BCL11B gene and its mRNA level in peripheral blood mononuclear cells (PBMCs) of ankylosing spondylitis (AS) patients in relation to healthy controls and evaluate their correlation with diseases ... سال انتشار: 2017
 

Anti-Cyclic Citrullinated Peptide Antibody and Rheumatoid Factor Isotypes in Iranian Patients with Rheumatoid Arthritis: Evaluation of Clinical Value and Association with Disease Activity

Abstract: In this study we determined the frequency, sensitivity and specificity of anti cyclic citrullinated peptides (anti-CCP) IgG antibody, total rheumatoid factor (RF-T), and RF isotypes in Iranian patients with rheumatoid arthritis (RA) and their association with age, clinical and serological parameters. Anti-CCP and RF-T and RF isotypes level were measured in 418 patients and 399 healthy controls by enzyme-linked immunosurbant assay (ELISA). Additionally, serum C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), ... سال انتشار: 2014
 

Association between Endoplasmic Reticulum Aminopeptidase-1 (ERAP-1) and Susceptibility to Ankylosing Spondylitis in Iran

Authers: Mahdi Mahmoudi1, 2, 3, Ahmad Reza Jamshidi2, Ali Akbar Amirzargar1, 3, Elham Farhadi1, Keramat Nourijelyani4, Sasan Fallahi2, 5, Mona Oraei3, Sahar Noori4, and Mohammad Hossein Nicknam1, 3

Abstract: Ankylosing Spondylitis (AS) is an inflammatory arthritis, which affects mainly spine and sacroiliac joints. According to recent studies, ERAP1 is the second most common candidate gene for AS susceptibility after HLA-B27. The aim of this study was to determine the association of ERAP1 gene polymorphisms with AS in Iranian population. The study group comprised 387 Iranian AS patients and 316 healthy controls from Iran. Using Real Time PCR allelic discrimination method, we genotyped four SNPs ... سال انتشار: 2012
 

HLA-B27 subtypes and tumor necrosis factor α promoter region polymorphism in Iranian patients with ankylosing spondylitis

Authers: Mohammad Hossein Nicknam, Mahdi Mahmoudi, Ali Akbar Amirzargar1, Ahmad Reza Jamshidi, Nima Rezaei, Behrouz Nikbin

Abstract: Background. HLA-B27 is an MHC class I molecule that is strongly associated with ankylosing spondylitis (AS). TNF-α, as an important cytokine in inflammatory joint disease, might have a role in the process of AS. This study was performed to determine HLA-B27 subtypes among Iranian patients with AS, and to investigate TNF-α gene polymorphisms in the patient groups. Methods. Ninety seven AS patients (74 HLAB27- positive and 23 HLA-B27-negative) and 137 healthy normal subjects (2 ... سال انتشار: 2009
