    GlossaryMatrix Metalloproteinase-9

    enzyme that breaks down extracellular matrix proteins

    Matrix Metalloproteinase-9 (MMP-9), also known as gelatinase B, is an enzyme that breaks down the extracellular matrix, which is the network of proteins and molecules surrounding cells. This process is crucial for tissue remodeling, wound healing, and the progression of certain diseases, including cancer and inflammatory conditions. Elevated levels of MMP-9 are often associated with pathological conditions such as chronic inflammation and tumor metastasis.
