The principal goal of this case-control study was to explore the potential of microRNA-146a (miRNA-146a) and tumor necrosis factor-alpha (TNF-\u03b1) as prognostic markers in RA patients. The study involved 50 RA patients taken from the Rheumatology unit at Marjan Hospital (Babylon) and 50 normal controls. Blood was collected from all patients and controls. Serum levels of TNF-\u03b1 were detected using an enzyme-linked immunosorbent assay (ELISA). Quantitative reverse transcription polymerase chain reaction (RT-qPCR) was performed to detect the miRNA-146a. The study found that women have a higher incidence of RA than men. The incidence was highest among patient\u2019s aged from15\u201360 years, with the greatest proportion being patients with disease duration of 1\u20133 years. Serum TNF-\u03b1 level in the RA patients were significantly higher than in the control group (p&lt;0.0001). Importantly, patients with stage IV rheumatoid arthritis showed a considerable high TNF-\u03b1 level (p&lt;0.0001). In conclusion, the results indicated that TNF-\u03b1 plays a central role in RA chronic inflammation and miRNA-146a has potential as an indicator of disease progression and a novel therapeutic target for treating cytokine-mediated inflammation in RA.<\/jats:p>","DOI":"10.55133\/eji.330203","type":"journal-article","created":{"date-parts":[[2026,4,14]],"date-time":"2026-04-14T11:02:54Z","timestamp":1776164574000},"page":"23-32","source":"Crossref","is-referenced-by-count":0,"title":["Investigating of correlation between microRNA-146a gene expression and TNF-\u03b1 Levels among rheumatoid arthritis patients in Babylon province"],"prefix":"10.55133","volume":"33","author":[{"given":"Zainab","family":"Nabat","sequence":"first","affiliation":[{"name":"Technical Institute of Babylon, Al-Furat Al-Awsat Technical University (ATU), Iraq."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"33636","published-online":{"date-parts":[[2026,4,1]]},"container-title":["The Egyptian journal of Immunology"],"original-title":[],"deposited":{"date-parts":[[2026,4,14]],"date-time":"2026-04-14T11:02:57Z","timestamp":1776164577000},"score":1,"resource":{"primary":{"URL":"https:\/\/ejimmunology.org\/vol-33-2-2026-03"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,4,1]]},"references-count":0,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2026,4,1]]},"published-print":{"date-parts":[[2026,4,1]]}},"URL":"https:\/\/doi.org\/10.55133\/eji.330203","relation":{},"ISSN":["1110-4902","2090-2506"],"issn-type":[{"value":"1110-4902","type":"print"},{"value":"2090-2506","type":"electronic"}],"subject":[],"published":{"date-parts":[[2026,4,1]]}}}
