Abstract:

Background: Osteoarthritis (OA), a chronic degenerative joint disease, is short of definitive therapeutic methods until now. More and more studies showed that long non-coding RNAs (lncRNAs) performed essential roles in OA. This study is aimed at investigating the effect of lncRNA SNHG1 on IL-1β-stimulated chondrocytes inflammatory injury in mice. Materials and Method: As the latest studies indicated, the mouse chondrocytes, stimulated by IL-1β, were used for constructing a model of inflammatory injury. The functions of SNHG1 overexpression or inhibition in regulating apoptosis, inflammation and Extracellular Matrix (ECM) in IL-1β injured chondrocytes were evaluated. Then, bioinformatics methods were used to screen possible targets of SNHG1, and the relationships among SNHG1, miRNA-143-3p, and Kruppel Like Factor 2 (KLF2) were verified by qRT-PCR and luciferase reporter gene assays. Furthermore, the functional mechanism of SNHG1 was explored through miR-143-3p overexpressed or the knockdown of KLF2 as recovery experiments. Results: SNHG1 was reduced in mouse chondrocytes stimulated by IL-1β. Moreover, overexpression of SNHG1 reduced apoptosis inhibited the inflammatory response and the degradation of ECM. Mechanistically, SNHG1, which functions as a sponger, directly bound to miRNA-143-3p. Additionally, transfection of miRNA-143-3p mimics reversed the inhibition of apoptosis and ECM degradation exerted by SNHG1 overexpression. SNHG1 exerted its function by indirectly regulating KLF2, a downstream target of miRNA-143-3p. Conclusion: Our study demonstrated that lncRNA SNHG1 protected chondrocytes against IL-1β- stimulated inflammatory injury by targeting miRNA-143-3p/KLF2 axis. It is suggested that SNHG1 might be a potential therapeutic target in OA.
