Historical Background

Matrix metalloproteinase-2 (MMP-2), previously named 72 kDa type IV collagenase or gelatinase A, belongs to the MMP family of calcium and zinc-dependent endopeptidases. MMPs were originally considered to be secreted proteases which play a major role in degrading extracellular matrix (ECM) proteins. In addition to its canonical role in ECM remodelling, MMP-2 has many nonmatrix extracellular and intracellular substrates (Schulz 2007; Spinale 2007). The list of identified MMP-2 substrates continues to grow and includes sarcomeric proteins, membrane receptors, cytokines, and growth factors. Consequently, MMP-2 regulates a vast range of physiological processes, from angiogenesis to wound healing and tissue remodeling. However, aberrant activation of MMP-2 contributes to many pathophysiological conditions, including inflammation, cancer metastasis, and cardiovascular diseases, making it a target of interest for therapeutic...
