چکیده
Background: Circular RNA-HIPK۳ (CircHIPK۳) has been shown to be aberrantly expressed in a variety of diseases, contributing to disease initiation and progression. The aim of the present study is to investigate the role of the circHIPK۳ RNA/microRNA-۱۲۴a interaction in the pathogenesis of rheumatoid arthritis (RA). Methods: This study included ۷۹ RA patients and ۳۰ control individuals. The patients involved were classified according to the disease activity score (DAS۲۸) into mild (۲۴ patients), moderate (۲۴ patients), and severe (۳۱ patients). Serum samples were collected to estimate the relative gene expression of circHIPK۳ RNA and its target gene microRNA-۱۲۴a by quantitative real time-PCR. Moreover, ELISA was used to detect the serum levels of monocyte chemoattractant protein-۱ (MCP-۱). Routine laboratory estimation of erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and rheumatoid factor (RF) was also done. Results: In all grades of RA groups, there was a significantly substantial elevation of circHIPK۳ RNA gene expression, with subsequent downregulation of miRNA-۱۲۴a when compared to the control group. CircHIPK۳ and microRNA-۱۲۴a expression have been established to be inversely linked. Also, estimation of serum levels of MCP-۱, ESR, CRP, and RF exhibited a significant increase in all grades of RA as compared to the control group. Conclusions: CircHIPK۳ and microRNA-۱۲۴a might be regarded as key players in the pathogenesis of RA. The cross-talk between them appears to be responsible for inducing joint inflammation by increasing MCP-۱ production. Targeting circHIPK۳ and microRNA-۱۲۴a, and their downstream adaptor molecules, poses a new challenge for RA therapy.کلیدواژه ها

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
