Extracellular matrix enzyme balance

Extracellular matrix (ECM) enzyme balance refers to the physiological equilibrium maintained between matrix-degrading enzymes, such as Matrix Metalloproteinases (MMPs) and ADAMTS, and their endogenous inhibitors, primarily Tissue Inhibitors of Metalloproteinases (TIMPs). This balance is essential for the regulated turnover of ECM components, which supports tissue structure, cell signaling, and repair. A shift in this balance toward excessive enzymatic activity is associated with tissue destruction in diseases like osteoarthritis, fibrosis, and cancer metastasis. Therapeutic strategies aim to restore this balance using small molecule inhibitors or biological agents, although achieving high selectivity remains a significant hurdle in drug development. Disrupting this delicate equilibrium can lead to unintended consequences, such as musculoskeletal toxicity, due to the diverse roles these enzymes play across different organ systems (Source: PubMed, PMID: 28414241; NIH, StatPearls: Matrix Metalloproteinases).
