The Interaction between microRNAs and the Wnt/β-Catenin Signaling Pathway in Osteoarthritis

Osteoarthritis (OA) is a chronic disease affecting the whole joint, which still lacks a disease-modifying treatment. This suggests an incomplete understanding of underlying molecular mechanisms. The Wnt/beta-catenin pathway is involved in different pathophysiological processes of OA. Interestingly, both excessive stimulation and suppression of this pathway can contribute to the pathogenesis of OA. microRNAs have been shown to regulate different cellular processes in different diseases, including the metabolic activity of chondrocytes and osteocytes. To bridge these findings, here we attempt to give a conclusive overview of microRNA regulation of the Wnt/beta-catenin pathway in bone and cartilage, which may provide insights to advance the development of miRNA-based therapeutics for OA treatment.

Automated summary

Osteoarthritis is a chronic disease that lacks disease-modifying treatment, with the Wnt/beta-catenin pathway playing a key role in its pathophysiology. Both excessive stimulation and suppression of this pathway can contribute to the development of OA. MicroRNAs have been found to regulate various cellular processes in different diseases, offering potential insights for the development of miRNA-based therapeutics for OA.
