Popis: Increasing evidence indicates that long non-coding RNAs (lncRNAs) play critical roles in osteoarthritis (OA). The present study aimed to investigate the underlying molecular mechanism of lncRNA musculin antisense RNA 1 (MSC-AS1) in OA. RT-qPCR was used to detect MSC-AS1 levels in cartilage tissues from patients with OA. The effects of MSC-AS1 knockdown on the viability and apoptosis in OA were evaluated via CCK-8 and TUNEL assays. The StarBase database was used to predict the binding sites between microRNA (miR)-369-3p and MSC-AS1 or JAK2, which were confirmed via the dual-luciferase reporter assay. The results demonstrated that MSC-AS1 expression was downregulated in OA. Functional analysis indicated that the addition of MSC-AS1 promoted viability and inhibited inflammation and the apoptosis of chondrocytes. In addition, MSC-AS1 regulated the survival of OA chondrocytes by sponging miR-369-3p. JAK2 was confirmed as a direct target of miR-369-3p, and MSC-AS1 regulated JAK2/STAT3 signaling via miR-369-3p in OA chondrocytes. Taken together, our results suggest that MSC-AS1 may regulate the miR-369-3p/JAK2/STAT3 signaling pathway to accelerate the viability, and inhibit inflammation and cell apoptosis in OA chondrocytes.
