Abstract
Recent studies have highlighted the potential role of several long non-coding RNAs (lncRNAs) in the pathogenesis of Behçet's disease (BD). This study investigated the expression profiles of lncRNA NEAT1 and lncRNA HOTAIR, and their target cytokine genes, IL-6 and TNF-α, in active and inactive BD patients. This cross-sectional study was conducted on peripheral blood mononuclear cells (PBMCs) obtained from 25 BD patients and 25 age-sex-matched healthy controls (HCs). BD activity was evaluated using the BDCAF (Behcet's Disease Current Activity Form) score. Correlation analysis assessed the relationship between BD activity and the expression levels of lncRNAs and their target cytokine genes. The diagnostic potential of the genes was evaluated using Receiver Operating Characteristic (ROC) curve analysis. The expression levels of NEAT1, HOTAIR, IL-6, and TNF-α were significantly higher in the BD group compared to the HCs. However, there was no significant correlation between the expression levels of these genes and BD activity or the involvement of various organs. A positive correlation was observed between HOTAIR gene expression and IL-6 (R = 0.594, P-value = 0.009) in the BD group. In contrast, no significant correlation was found between HOTAIR and TNF-α or between NEAT1 and TNF-α or IL-6. The ROC curve analysis indicated strong diagnostic potential for the lncRNAs, with area under the curve (AUC) values of 0.90 for NEAT1 and 0.86 for HOTAIR. The elevated expression levels of NEAT1 and HOTAIR in BD patients suggest their potential involvement in the disease's pathogenesis, indicating promising targets for future diagnostic and therapeutic strategies in BD.
