Therapeutic Potential of Traditional Chinese Medicine Against Osteoarthritis: Targeting the Wnt Signaling Pathway.

Abstract

Osteoarthritis (OA) is a chronic degenerative articular disease that leads to physical disability and reduced quality of life. The key pathological events in OA are cartilage degradation and synovial inflammation. Conventional therapies often lead to adverse effects that some patients are unwilling to endure. Traditional Chinese Medicines (TCMs) have long been known for their efficacy in treating OA with minimal side effects. The wingless-type (Wnt) signaling pathway is believed to play a role in OA progression, but there is still a lack of comprehensive understanding on how TCM may treat OA via the Wnt signaling pathway. This study aims to fill this gap by reviewing relevant research on the association between the Wnt signaling pathway and cartilage degradation and synovial inflammation in OA. Meanwhile, we also summarized and categorized TCMs and their active components, such as alkaloids, polysaccharides, flavonoids, sesquiterpene lactones, etc., which have shown varying efficacy in treating OA through modulation of the Wnt/[Formula: see text]-catenin signaling pathway. This work underscores the pivotal role of the Wnt signaling pathway in OA pathogenesis and progression, suggesting that targeting this pathway holds promise as a prospective therapeutic strategy for OA management in the future. TCMs and their active components have the potential to alleviate OA by modulating the Wnt signaling cascade. Harnessing TCMs and their active components to regulate the Wnt signaling pathway presents an encouraging avenue for delivering substantial therapeutic benefits to individuals with OA.
