Proteomic Analysis of Tendon Extracellular Matrix Reveals Disease Stage- specific Fragmentation and Differential Cleavage of COMP ( Cartilage Oligomeric Matrix Protein)*
Background: Tendon disease is characterized by extensive remodeling of the extracellular matrix. Results: Novel COMP cleavage fragments were identified in both an in vitro inflammatory model and natural disease. Conclusion: Inflammatory mediators drive distinct COMP fragmentation at different stages of tendon disease. Significance: Novel COMP neo-terminal fragments provide opportunities for develo
