Matrix metallopeptidase 9 (MMP-9), also known as 92 kDa type IV collagenase, 92 kDa gelatinase or gelatinase B (GELB), is an enzyme that in humans is encoded by the MMP9 gene.[1]

Function[edit]

Proteases of the matrix metalloproteinase (MMP) family are involved in the breakdown of extracellular matrix in normal physiological processes, such as embryonic development, reproduction, angiogenesis, bone development, wound healing, cell migration, learning and memory, as well as in pathological processes, such as arthritis, intracerebral hemorrhage,[2] and metastasis.[3] Most MMPs are secreted as inactive proproteins which are activated when cleaved by extracellular proteinases. The enzyme encoded by this gene degrades type IV and V collagens and other extracellular matrix proteins.[4] Studies in rhesus monkeys suggest that the enzyme is involved in IL-8-induced mobilization of hematopoietic progenitor cells from bone marrow, and murine studies suggest a role in tumor-associated tissue remodeling.[1]

Thrombospondins, intervertebral disc proteins, regulate the effective levels of matrix metalloproteinases (MMPs) 2 and 9, which are key effectors of ECM remodeling.[5]

Neutrophil action[edit]

Gelatinase B, along with elastase, appears to be a regulatory factor in neutrophil migration across the basement membrane.[6]

Gelatinase B plays several important functions within neutrophil action, such as degrading extracellular matrix, activation of IL-1β, and cleavage of several chemokines.[7] In a mouse model, Gelatinase B deficiency resulted in resistance to endotoxin shock, suggesting that Gelatinase B is important in sepsis.[8]

Angiogenesis[edit]

Gelatinase B may play an important role in angiogenesis and neovascularization. For example, gelatinase B appears to be involved in the remodeling associated with malignant glioma neovascularization.[9] It is also a key regulator of growth plate formation- both growth plate angiogenesis and the generation of hypertrophic chondrocytes. Knock-out models of Gelatinase B result in delayed apoptosis, vascularization, and ossification of hypertrophic chondrocytes.[10] Lastly, there is significant evidence that Gelatinase B is required for the recruitment of endothelial stem cells, a critical component of angiogenesis [11]

Wound repair[edit]

Gelatinase B is greatly upregulated during human respiratory epithelial healing.[12] Using a gelatinase B deficient mouse model, it was seen that gelatinase B coordinated epithelial wound repair and deficient mice were unable to remove the fibrinogen matrix during wound healing.[13] When interacting with TGF-ß1, Gelatinase B also stimulates collagen contraction, aiding in wound closure.[14]

Clinical significance[edit]

Gelatinase B has been found to be associated with numerous pathological processes, including cancer, immunologic and cardiovascular diseases.

Arthritis[edit]

Elevated gelatinase B levels can be found in the cases of rheumatoid arthritis[15] and focal brain ischemia.[16]

Cancer[edit]

One of Gelatinase B most widely-associated pathologyis the relationship to cancer, due to its role in extracellular matrix remodeling and angiogenesis. For example, its increased expression was seen in a metastatic mammary cancer cell line.[17] Gelatinase B plays a central role in tumor progression, from angiogenesis, to stromal remodeling, and ultimately metastasis.[18] However, because of its physiologic function, it may be difficult to leverage Gelatinase B inhibition into cancer therapy modalities. However, Gelatinase B has been investigated in tumor metastasis diagnosis- Complexes of Gelatinase B/Tissue Inhibitors of Metalloproteinases are seen to be increased in gastrointestinal cancer and gynecologic malignancies [19]

MMPs such as MMP9 can be involved in the development of several human malignancies, as degradation of collagen IV in basement membrane and extracellular matrix facilitates tumor progression, including invasion, metastasis, growth and angiogenesis.[20]

Cardiovascular[edit]

MMP-9 levels increase with the progression of idiopathic atrial fibrillation.[21]

Gelatinase B has been found to be associated the development of aortic aneurysms,[22] and its disruption prevents the development of aortic aneurysms.[23] Doxycycline suppresses the growth of aortic aneurysms through its inhibition of matrix metalloproteinase 9.[24]
