ABSTRACT
Osteoarthritis (OA) is a chronic degenerative disease that commonly affects the elderly. Current drug therapies for treating OA may cause adverse side effects, and so there remains a need to develop alternative treatments. Bergapten (BG) is a coumarin phytohormone that is widely found in fruits and has antioxidative and anti-inflammatory effects. Here, we tested the hypothesis that BG may restrict the progression of OA by examining its effect on OA chondrocytes. We observed that BG significantly ameliorated interleukin (IL)-1ß-induced expression of inflammatory cytokines and mediators, including interleukin 1 (Il-1), interleukin 6 (Il-6), tumor necrosis factor α (Tnf-α), cyclooxygenase 2 (Cox-2) and matrix metalloproteinase 13 (Mmp-13), maintained chondrocyte phenotype, and promoted the secretion of cartilage-specific extracellular matrix. We provide evidence that BG exerts its anti-inflammatory effect by activating the ANP32A/ATM signaling pathway, which was recently verified to be associated with OA. In conclusion, these findings indicate that BG may be a potential candidate for treatment of OA.
