Implication
Review reveals disrupted metabolic balance drives progressive cartilage degradation in osteoarthritis, highlighting critical molecular targets for disease-modifying therapies.
Key Points
- To review the balance between anabolic building processes and catabolic breakdown activities in cartilage tissue, identifying potential molecular targets to treat osteoarthritis.
- Synthesized molecular evidence on extracellular matrix turnover and tissue repair mechanisms in healthy and osteoarthritic cartilage.
- Evaluated crosstalk among proanabolic, antianabolic, procatabolic, and anticatabolic signaling and metabolic pathways.
- Cartilage degradation outpaces repair capacity in osteoarthritis because elevated catabolic and antianabolic factors suppress matrix integrity.
- Anabolic signaling increases alongside tissue damage, but this compensatory repair response fails due to both quantitative and qualitative insufficiency of newly formed matrix.
