Abstract: The gene encoding signal transducer and activator of transcription 4 (STAT4) has been documented to be associated with rheumatoid arthritis (RA) in several populations. The aim of this study was to determine the association of the STAT4 gene polymorphism (rs7574865) with RA in the Iranian population. Methods: This study included 612 Iranian RA patients and 389 healthy control subjects. For all samples, DNA was genotyped for STAT4 G>T (rs7574865) polymorphism using the MGB TaqMan Allelic Discrimination ... سال انتشار: 2016

Abstract: Prolonged activation of dermal fibroblasts is the main cause of progressive fibrosis in systemic sclerosis (SSc). It seems that inhibition of apoptosis in SSc fibroblasts deregulates fibrosis. MicroRNA-21 (miR-21) is a pro-fibrotic factor with high expression in lesional areas of SSc skin and fibroblasts. Methods The effects of miR-21 on expression of Bcl-2 and Bax, two apoptotic genes, in dermal fibroblasts of SSc patients were evaluated using real-time polymerase chain reaction and Western blot analysis. Apoptotic ... سال انتشار: 2016
 

Polymorphism of killer cell immunoglobulin-like receptors (KIR) and their HLA ligands in Graves’ disease

Authers: Romina Dastmalchi • Ali Farazmand • Sina Noshad • Mohamad Mozafari • Mahdi Mahmoudi • Alireza Esteghamati • Aliakbar Amirzargar

Abstract: Killer immunoglobulin-like receptors (KIR) play a pivotal role in commencement of both innate and adaptive immunity. Dysregulation of KIRs is associated with an increased risk of autoimmune disorders. This study was designed to assess whether polymorphisms in KIR gene family and their respective HLA class I ligands confer protection or susceptibly to Graves’ disease (GD). Eighty patients with confirmed GD (cases) and 176 healthy unrelated subjects (controls) were recruited. Using a polymerase chain reaction sequence-specific primer directed method (PCR-SSP), presence ... سال انتشار: 2014
