Abstract

The aim of this study was to investigate the potential mechanisms of long noncoding (lnc) RNA Just proximal to X‑inactive specific transcript (JPX) in interleukin (IL)‑1β‑stimulated chondrocytes. Human C28/I2 chondrocytes were treated with IL‑1β to simulate osteoarthritic (OA) injury. The expression levels of JPX, microRNA (miRNA/miR)‑25‑3p, and peptidylprolyl isomerase D (PPID) were measured using reverse transcription‑quantitative PCR or western blotting. The IL‑1β‑stimulated injury was assessed using a Cell Counting Kit‑8 assay, flow cytometry, and western blot analysis. The targeted relationship between miR‑25‑3p, JPX, and PPID was verified using a dual‑luciferase reporter and RNA immunoprecipitation (RIP) assays. The results showed that JPX expression was upregulated in OA patients and IL‑1β‑stimulated chondrocytes. JPX knockdown enhanced cell viability and suppressed apoptosis of IL‑1β‑stimulated chondrocytes. miR‑25‑3p inhibition rescued the inhibitory effect of JPX knockdown on IL‑1β‑stimulated injury. PPID overexpression eliminated the effects of JPX knockdown on IL‑1β‑stimulated chondrocytes. In conclusion, JPX knockdown increased cell viability and reduced apoptosis in IL‑1β‑stimulated chondrocytes, and this involved modulation of a miR‑25‑3p/PPID axis.
