Epigenetic mechanisms underlying the aberrant catabolic and anabolic activities of osteoarthritic chondrocytes

The development of disease-modifying pharmacologic therapy for osteoarthritis currently faces major obstacles largely because the pathogenetic mechanisms for the development of osteoarthritis remain unclear. Previous studies suggest that the alterations in expression of catabolic and anabolic genes in articular chondrocytes may be involved in the pathogenesis of osteoarthritis. However, the regulatory mechanisms for gene expression in...
