It has an extremely streamlined structure comprising only a signal peptide, pro-domain, and catalytic domain, lacking the hinge region and hemopexin-like domain commonly found in other MMPs. The HEXXHXXGXXH motif in its catalytic domain exerts proteolytic activity by chelating zinc ions, enabling it to degrade basement membrane components such as laminin, fibronectin, and type IV collagen, as well as activate inflammatory factors like pro-TNF-α and cleave E-cadherin to promote epithelial-mesenchymal transition. Under physiological conditions, it participates in tissue remodeling, wound healing, and gland development, whereas under pathological conditions, MMP-7 is highly expressed in various malignancies including gastric, colorectal, pancreatic, and renal cell carcinomas, closely correlating with poor prognosis through promoting tumor invasion, angiogenesis, and lymph node metastasis. Plasma MMP-7 level detection has demonstrated favorable diagnostic value (AUC 0.80-0.91) and independent prognostic predictive capability, and can assess pathological response to neoadjuvant therapy in pancreatic cancer patients, making it a highly promising tumor biomarker and therapeutic target.\u003c\/span\u003e\u003c\/p\u003e\u003c\/div\u003e\u003ch4\u003eProtocol\u003c\/h4\u003e\u003cdiv\u003e\n\u003cp style=\"text-align:left;\"\u003e\u003cstrong\u003eAssay protocol\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePrinciple:\u003c\/strong\u003e\u003cspan\u003e Measured by its ability to cleave a peptide substrate, Mca-PLGL-Dpa-AR-NH2.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMaterials\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"margin-right:8px;\"\u003e1.\u003c\/span\u003e\u003cspan\u003eAssay Buffer: 50 mM Tris, 10 mM CaCl2, 150 mM NaCl, 0.05% (w\/v) Brij 35, pH 7.5 (TCNB)\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"margin-right:8px;\"\u003e2.\u003c\/span\u003e\u003cspan\u003eMMP-7\/PUMP1 His Tag Protein, Human (active enzyme)\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"margin-right:8px;\"\u003e3.\u003c\/span\u003e\u003cspan\u003ep-aminophenylmercuric acetate (APMA) (Aladdin, Catalog # P649286)\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"margin-right:8px;\"\u003e4.\u003c\/span\u003e\u003cspan\u003eFluorogenic Peptide Substrate: MCA-Pro-Leu-Gly-Leu-DPA-Ala-Arg-NH2 (R\u0026amp;D, ES001)\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"margin-right:8px;\"\u003e5.\u003c\/span\u003e\u003cspan\u003eCalibration standard: MCA-Pro-Leu-OH (Shyuanye, T77046)\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"margin-right:8px;\"\u003e6.\u003c\/span\u003e\u003cspan\u003e96 ELISA Removable Plate, Black, High binding (GENEVER, Catalog # GMO2-96H)\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"margin-right:8px;\"\u003e7.\u003c\/span\u003e\u003cspan\u003ePlate Reader (PerkinElmer, excitation 320 nm, and emission 405 nm)\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eProduce\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan style=\"margin-right:8px;\"\u003e1.\u003c\/span\u003e\u003cspan\u003eActivate MMP-7 at 100 μg\/mL with 1 mM APMA in Assay Buffer.
