Coniferaldehyde prevents articular cartilage destruction in a murine model via Nrf2/HO‑1 pathway
Osteoarthritis (OA) is the most prevalent joint disorder characterized by progressive cartilage damage, resulting in gradual disability among the elderly. We previously provided in vivo evidence that nuclear factor erythroid 2‑related factor 2 (Nrf2) deficiency is associated with the development of OA. It has been reported that coniferaldehyde (CFA) acts as a potential Nrf2 activator. The aim of the present study was to investigate the protective effects of CFA against osteoarthritis. A murine model of surgical‑induced OA was used in the present study and CFA was administered by peritoneal injection every day, and the knee joints were assessed by histological analysis. The results demonstrated that CFA activated the Nrf2 signaling pathway in primary chondrocytes and articular cartilage from the knee joints. Cartilage damage in mice subjected to the destabilization of the medial meniscus was evidently alleviated by CFA treatment. CFA also robustly suppressed apoptosis induced by H2O2 in murine chondrocytes and reduced the expression of matrix metalloproteinase (MMP)1, MMP3, interleukin (IL)‑1 and IL‑6 in vivo. On the whole, the findings suggested that CFA exerts a therapeutic effect against OA, and the activation of the Nrf2/heme oxygenase‑1 pathway may play a crucial role in CFA‑mediated cartilage protection.
