ABSTRACT
Osteoarthritis (OA) is a chronic musculoskeletal degeneration disease, resulting in severe consequences such as chronic pain and functional disability. Owing to the complex pathology, there are currently available preventative clinical therapies for OA. Several studies have reported the potential anti-inflammatory effects of byakangelicin (BYA), a component of the Angelica dahurica root extract; however, the effects of BYA in OA remain unknown. In this study, we investigated the protective effects of BYA in interleukin (IL)-1ß-induced mouse chondrocytes in vitro and on surgical destabilization in a medial meniscus (DMM) mouse OA model in vivo. In vitro, BYA treatment inhibited IL-1ß-mediated inducible nitric oxide synthase, cyclooxygenase-2, tumor necrosis factor-alpha, and IL-6 expression. Moreover, BYA promoted the expression of type two collagen and aggrecan but inhibited the expression of thrombospondin motifs 5 and matrix metalloproteinases, leading to degradation of the extracellular matrix. In addition, BYA mechanistically suppressed nuclear factor-kappa B signaling in the IL-1ß-induced chondrocytes. The protective effects of BYA in OA development were also observed in vivo using the DMM model. In conclusion, our results highlight BYA as a candidate for OA treatment and prevention.
