Gelatinase B (EC 3.4.24.35, 92-kDa gelatinase, matrix metalloproteinase 9, type V collagenase, 92-kDa type IV collagenase, macrophage gelatinase, 95 kDa type IV collagenase/gelatinase, collagenase IV, collagenase type IV, gelatinase MMP 9, MMP 9, type IV collagen metalloproteinase) is an enzyme.[1][2][3] This enzyme catalyses the following chemical reaction
- Cleavage of gelatin types I and V and collagen types IV and V
This enzyme is similar to gelatinase A, but possesses a further domain. Regarding its structure, Gelatinase B has domains which can bind with gelatin, laminin, and collagens type I and IV- collagenases do not possess these binding domains.[4]

Function
Due to its role in cleaving collagen in the extracellular matrix, gelatinase B has multiple functional roles in normal physiology.
Neutrophil action
Gelatinase B, along with elastase, appears to be a regulatory factor in neutrophil migration across the basement membrane.[5] Gelatinase B plays several important functions within neutrophil action, such as degrading extracellular matrix, activation of IL-1β, and cleavage of several chemokines.[6] In a mouse model, Gelatinase B deficiency resulted in resistance to endotoxin shock, suggesting that Gelatinase B is important in sepsis.[7]
Angiogenesis
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.[8] 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.[9] Lastly, there is significant evidence that Gelatinase B is required for the recruitment of endothelial stem cells, a critical component of angiogenesis [10]
Wound repair
In in vitro experiments, it has been demonstrated that gelatinase B is greatly upregulated during human respiratory epithelial healing.[11] 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.[12] When interacting with TGF-ß1, Gelatinase B also stimulates collagen contraction, aiding in wound closure.[13]
Pathology
Gelatinase B has been found to be associated with numerous pathological processes, including immunologic and vascular diseases. For example, it has been implicated in the development of aortic aneurysms,[14] and its disruption prevents the development of aortic aneurysms.[15] Elevated gelatinase B levels can also be found in the cases of rheumatoid arthritis [16] and focal brain ischemia.[17]
However, one of its most widely studied associated pathology is the relationship between Gelatinase B and 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.[18] A.R. Farina and others have argued that Gelatinase B plays a central role in tumor progression, from angiogenesis, to stromal remodeling, and ultimately metastasis.[19] 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 [20]
