OBJECTIVES
In this study, we aimed to examine the efficacy of micro ribonucleic acid (miRNA)-23a-5p in gouty arthritis and to investigate its possible mechanism.
MATERIALS AND METHODS
Gouty arthritis in rat was established by intraarticular injection of 0.2 mL monosodium urate crystal (20 mg/mL) inside knee joint cavity. THP-1 cell was induced using lipopolysaccharides (LPS) for model.
RESULTS
Serum miRNA-23a-5p expression levels were increased in rats of gouty arthritis. However, overexpression of miRNA-23a-5p promoted inflammation and induced myeloid differential protein-88 (MyD88)/nuclear factor-kappa B (NF-κB) pathway by induction toll-like receptor-2 (TLR2) . The inhibition of TLR2 attenuated the pro-inflammation effects of miRNA-23a-5p in inflammation in model of gouty arthritis.
CONCLUSION
Our findings demonstrate that miRNA-23a-5p is a biomarker for gouty arthritis and promotes inflammation in rats of gouty arthritis via MyD88/NF-κB pathway by targeting TLR2.
目的
在本研究中，我们旨在检测微小核糖核酸（miRNA）-23a-5p在痛风性关节炎中的作用，并探究其可能的机制。
材料与方法
通过在大鼠膝关节腔内注射0.2 mL尿酸钠晶体（20 mg/mL）建立痛风性关节炎大鼠模型。使用脂多糖（LPS）诱导THP-1细胞作为模型。
结果
痛风性关节炎大鼠血清miRNA-23a-5p表达水平升高。然而，miRNA-23a-5p的过表达通过诱导Toll样受体2（TLR2）促进炎症反应并激活髓样分化蛋白88（MyD88）/核因子κB（NF-κB）信号通路。在痛风性关节炎模型中，抑制TLR2可减弱miRNA-23a-5p的促炎作用。
结论
我们的研究结果表明，miRNA-23a-5p是痛风性关节炎的生物标志物，并且通过靶向TLR2，经MyD88/NF-κB信号通路促进痛风性关节炎大鼠的炎症反应。
