In one study, miR‐4441 was identified among several candidate microRNAs due to its strong association with RA‐target genes. Notably, the expression of miR‐4441 was found to be significantly reduced in the plasma of RA patients (fold change = 1.7) compared to healthy individuals, suggesting that diminished levels of this microRNA may play a role in the disease’s pathogenesis."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": ""}]}, {"type": "t", "text": "\n\n"}, {"type": "p", "children": [{"type": "t", "text": "\nFurther analyses demonstrated that miR‐4441 expression levels correlate with key metabolic and inflammatory markers—including liver enzymes, cholesterol, phosphorus, and vitamin D3—indicating that this microRNA may serve as an important molecular bridge between metabolic dysregulation and inflammatory processes in rheumatoid arthritis.
